How do you get 60cm2 in question 1?

How Do You Get 60cm2 In Question 1?

Answers

Answer 1

Answer:

Step-by-step explanation:

4*2=8, thats one rectangle (side)

8*2 is 16, thats TWO rectangles (sides)

7*4=28, thats one rectangle (front)

28*2=56, thats TWO rectangles (front and back)

7*2=14, thats one rectangle (top)

14*2=28, thats TWO rectangles (top and bottom)

add all of these surface areas together

TWO rectangles + TWO rectangles + TWO rectangles

28+56+16=100

As you can see, the 60cm2 is incorrect. 100cm2 is the real surface area of the shape

Find the slope of the line that passes through the points (9, -2) and (-3. -2). Write the equation in
slope-intercept form.

Answers

Answer:

slope: zero/none

equation: y = -2

Step by Step:

1) find the slope - change in y / change in x

-2+2/9+3

0/12

0 <- zero slope = no slope

2) plug in and solve for y-intercept

( -3, -2 )

-2=(0*-3)+b

b=-2

because the slope was zero, we know that it's a horizontal line

therefore the only equation we can get from this is a y= equation

3) plug in values to get equation

y = -2

slope is zero

What is 11 1/20 as a decimal?

Answers

11,05

Step-by-step explanation:

11 1/20

= (11 × 20 + 1)/20

= (220 + 1)/20

= 221/20 → times 5

= 1105/100

= 11,05

Answer:

11.05

Step-by-step explanation:

To convert a fraction to a decimal, multiply the fraction by [tex]\frac{x}{x}[/tex], x being the number that will multiply with the denominator to equal 100.

In this case, the value of x would be 5 because 20 × 5 = 100.

Now, multiply [tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex]:

[tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{5}{100}[/tex]

5 hundredths is equal to 0.05, so 11[tex]\frac{1}{20}[/tex] = 11.05.

Answer:

m ∠ 2 = 19 * 3 = 57°

Step-by-step explanation:

m ∠ 1 = x

m ∠ 2 = 3x

m ∠ 1 + m ∠ 2 = 76°

3x + x = 76°

4x = 76°

Divide both sides by 4;

x = 19°

m ∠ 1 = 19°

m ∠ 2 = 19 * 3 = 57°

Q. Which of these represents stope-intercept form of a linear equation?
answer choices
A)Ax+By=c
B)y-yı = m-x)
C)y=kx
D)y=mx + b

Answers

Answer:

D

Step-by-step explanation:

this is so easy just plug the question in

Answer:

D.y= mx + b

Step-by-step explanation:

Slope-intercept is a specific form of linear equations. It has the following general structure

y= mx + b

Here, m can be any two real numbers. For example, these are linear equations in slope-intercept form:

y=2x+1

y=-3x+2.7y

y=10-100x

On the other hand, these linear equations are not in slope-intercept form:

2x+3y=5

y-3=2(x-1)y−3=2(x−1)

x=4y−7

Slope-intercept is the most prominent form of linear equations

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 400 nails. The contractor bought 2 more small boxes than large boxes, which altogether had 1950 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.

Answers

Answer:

The number of small and large boxes purchased are:

2 small boxes.

6 large boxes.

Step-by-step explanation:

To solve the unknowns, two equations must be established with the information provided:

150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)

Y = 3X (Large boxes are triple the small ones)

Then equation 2 is replaced in equation one and variable X is cleared:

150X + 400 (3X) = 2700

150X + 1200X = 2700

1350X = 2700

X = 2700/1350

X = 2

Finally, the value of X is replaced in equation 2 to find the number of large boxes:

Y = 3X

Y = 3 (2)

Y = 6

when you started your homework assignment, your friend already had 6 exercises done. You can do about 3 exercises per minute, whereas your friend can only do 2 exercises per minute. how many minutes will it take you to catch up to your friend.

Answers

Considering they're getting 2 more each wave, we can apply simple math to this.

6+2 and onwards,

0+3 and onwards until it surpasses the first value.

I calculated this, and it seems it takes around 6 minutes to catch up to the friend at 18 exercises.

It will take you 6 minutes to catch up to your friend.

Given that when you started your homework assignment, your friend already had 6 exercises done.

You can do about 3 exercises per minute, whereas your friend can only do 2 exercises per minute.

So, your friend is ahead by 6 exercises, and you can complete 3 exercises per minute while your friend can complete 2 exercises per minute.

This means you're gaining on your friend's lead at a rate of 3 - 2 = 1 exercise per minute.

To catch up to your friend's lead of 6 exercises, you'll need 6 minutes, because you'll be closing the gap by 1 exercise per minute.

So, it will take you 6 minutes to catch up to your friend.
