What we know:

How to solve:

    By using our knowledge of ratios and substitution, we can solve these problems.

First problem

Set up ratio                                                             7.5:15

Find GCF                                                                (7.5:15)/7.5

Simplify                                                                   1:2

Solution:                                                                  2  

Second problem

Set up equation                                                     (x/10) = (6/7.5)

Rewrite                                                                   (x/10) = (60/75)

Simplify                                                                   (x/10) = (4/5)

Common denominator                                          (x/10) = (8/10)

Isolate variable                                                      [(x/10) = (8/10)]*10

Simplify                                                                    x = 8

Solution:                                                                  8

Third Question

where x represents the new width, y represents the new length, and A represents the new area.

Set up equation                                                    A = xy

Substitute                                                              A = (2*4)(2*6)

Simplify                                                                  A = (8)(12)

Simplify                                                                  A = 96

Solution:                                                                96 cm^2                                                      

Fourth Question

Where x represents the unknown length in miles

Set up equation                                                    (21:3) = (x:5)

Rewrite in fraction form                                        [(21/3)] /3 = (x/5)

Simplify                                                                   (7/1) = (x/5)

GCF                                                                        5(7/1) = (x/5)

Isolate variable                                                       [(35/5) = (x/5)]*5

Solution:                                                                  35 miles = x

Problem 1:

If the scale factor is 2, then the area of a square with the side measurement of 7.5 units should be (due to areas being squared) 1/2^2 of the square with the side measurement of 15 units. Let's solve this:

(1/2^2)(15*15) = (7.5*7.5)

(1/4)(15^2) = (7.5^2)

225/4 = 56.25

56.25 = 56.25

Therefore, a scale factor of 2 is correct.

Problem 2:

If x = 8, then 8/10 should equal 6/7.5. Let's solve this:

when x = 8:

8/10 = 6/7.5

0.8 = 0.8

Therefore, x = 8 is a correct solution.

Problem 3:

If a scale factor of 2 creates the new area of 96 cm^2, then the old area of (6*4) should be (due to areas being squared) 1/2^2 of the new area. Let's solve this:

(1/2^2)(96) = (6*4)

(96/4) = 24

24 = 24

Therefore, the new area is 96 cm^2.

Problem 4:

If the houses are 35 miles apart, then 3 in./21 mi. should be equal to 5 in./35 mi. Let's solve this:

(21/3) = (35/5)

7 = 7

Therefore, the houses are 35 miles apart.

Step-by-step explanation:

mode is the number that appears the most often.

Answer:

102

Step-by-step explanation:

The mode means the number that repeats the most in a set of numbers.

102, 56, 77, 102, 81, 72, 55

The number that repeats 2 times is 102.

Answer:

<

Step-by-step explanation:

The reason why this is your answer is that because the two numbers are in Negatives, the higher the number closer to 0, the larger than it is to a number farther to zero on the left side of the number line.

so hence, your answer is <

Step-by-step explanation:

-4 < -1

Note:

< → Less than

> → Greater than

= → Equal

Explain:

if you put -4 and -1 on a number line it on the left. But -4 is more on the left than -1. Thus, we can know that -4 is less than -1.

Answer:

Width = 6

Step-by-step explanation:

7*2 = 14

26-14=12

12/2= 6

The required width of the sandbox made by Dahlia is 6 meters.

Given that,
Dahlia wants to build a sandbox that has a perimeter of 26 meters and a length is 7 meters, what is the width of their sandbox is to be determined.

Perimeter is the measure of the figure on its circumference.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification

Here,
the perimeter of the box = 26
2 × length + 2×width = 26
2 × 7 + 2 × width = 26
14 + 2 × width = 26
2 × width = 26 - 14
width = 12 / 2
width = 6 meters,

Thus, the required width of the sandbox is 6 meters.

#SPJ2

Answer:

Part A: impossible

Part B: Either equal or blue

Part C: 9 green and 2 blue were added

Step-by-step explanation:

Part A:

The only colors included in this problem are red, blue, and green. There is no black colored pencil, therefore, it is impossible to get one from the box.

Part B:

I'm not sure what you're asking in this question, but I will give you the two choices. If it is before the additional 11 colored pencils are added to the box, the chance of drawing a red and the chance of drawing a blue will be equal, because both of them have 11 of each color. If it is after the additional 11 colored pencils are added to the box, then the chance of drawing a blue colored pencil will be greater than the chance of drawing a red colored pencil. After the 11 colored pencils are added, there are 13 blue and 11 red. The blue is greater.

Part C:

The least number of green colored pencils added has to be 9, because the chance of drawing a green pencil is now greater than the chance of drawing a red pencil. If we add 8 more green pencils, the likelihood would be the same. Therefore, the number of green colored pencils added has to be at least 9. If we have the last 2 colored pencils be blue, then there would be 11 red, 13 blue, and 12 green. This fits all the conditions, therefore, adding 9 green colored pencils and 2 blue colored pencils is the answer.

Step-by-step explanation:

we know that

surface area of the prism=2*area of the base+perimeter of the base*height

step 1

find the area of the base

area of the base=length* width

length=5 cm

width=4 cm

area of the base=5*4-----> 20 cm²

step 2

find the perimeter of the base

perimeter=2*[length+width]-----> 2*[5+4]----> 18 cm

step 3

height=7 cm

step 4

find the surface area

surface area of the prism=2*area of the base+perimeter of the base*height

surface area of the prism=2*20+18*7----> 166 cm²

The given inequality y < -4 is shown in the attached graph. The correct answer would be an option (B).

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Inequalities with "< or > "symbols are shown with a dashed line to indicate that the line is not inside the area. Inequalities involving symbols are depicted with a solid line to indicate that the line is included in the region.

We have been the given inequality y < -4

Rearrange the equation such that "y" is on the left and all other variables are on the right.

Plot the "y=" line (a solid line for y or y, and a dashed line for y or y>). The shade above the line for a "greater than" (y> or y), or below the line for a "less than" (y or y).

Hence, the given inequality y < -4 is have shown in the attached graph.

0.30

Answer:

9 laps or 3600 meters.

Step-by-step explanation:

First you want to find who has ran the furthest and the least distance.

So we have Rory ran the most with 14 laps or 5600 meters and Daniel who ran the least with 5 laps or 2000 meters.Next we subtract becuase when you say to "find the difference" it means to subtract.We subtract  if you want to find the laps we do 14-5 and if you want to find the number of meters we do 5600-2000.

In order to factor this expression, we should divide both terms of this binomial (a polynomial with 2 terms) by 4 (the greatest common factor)

Note:- We usually factor out the Greatest Common Factor, or the GCF.

Divide:-

m

8

Add the terms:-

m+8

Put parentheses around them:-

(m+8)

Put 4 outside the parentheses:-

4(m+8)

If you wonder whether or not you've factored correctly, you can use the distributive property & distribute :)

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25        WRONG

- 5x - 25 = 78

- 5x - 25 + 25 = 78 + 25

- 5x                  = 103

x = - 103/5

x = - 20,6

Answer:

Step-by-step explanation:

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25  <== this is where the error was made.

Step 2: −5x = 53

Step 3: = −5x/−5=53/−5

Step 4: x = −53/5

Right steps:

−5x − 25 = 78

Step 1: −5x − 25 + 25 = 78 + 25

Step 2: −5x = 103

Step 3: −5x/−5 = 103/−5

Step 4: x = 103

Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

Step-by-step explanation:

Was having trouble looking at the images and couldn't tell if it was a + or a division sign.

Step 1: Find the area of the rectangle

Area of a rectangle = base x height

Area of the rectangle = 4 x 10 = 40

Step 2: Find the area of the half-circle

Area of a circle = pi x r^2

---In this case, since we only have half of a circle, we will need to divide the area by 2 (or multiply by 1/2).

---We are also only given the diameter here. The radius of a circle is half of its diameter, therefore the radius of this half-circle is 5.

Area of the half-circle = (pi x 5^2) / 2 = (3.14 x 25) / 2 = (78.5) / 2 = 39.25

Rounded area of the half-circle = 39.3

Step 3: Find the area of the figure

Now that we know both parts of the figure, all that's left to do is add them together to find the total area.

40 + 39.3 = 79.3

Answer: 79.3

Soccer game lasts 2 hours and 15 minutes

The game starts at 11:00 A

The park closes at 6:30

The first thing we need to do is to find when Hamid's soccer game finishes

2 1/4 + 11:00 = 13 1/4 = 1:15

(uh so don't know if this is the correct formula for finding time but the answer is correct)

Guessing that each game lasts 2 hrs and 15 mins, we do the same thing

1.25 + 2.25 = 3.75 = 3 3/4 = 3:45

(i added decimals bc i find it the easiest way for me) 1 game

3.75 + 2.25 = 6 (another game)

The answer is 2 games including Hamid's soccer game.
