Step-by-step explanation:

Allison and Lindsey each measured their bedrooms for new carpeting. They found
that both rooms were square, with the length of Lindsey's room 3 feet longer than
Allison's. If Lindsey needed 225 square feet of carpeting, how many square feet of
carpeting did Allison need?

Answers

Answer:

Step-by-step explanation:

Let's assume that the length of a side of Allison's room as x

So, Lindsey's room = x + 3

If Lindsey's room needs 225 sq. feet of carpeting, then   x + 3 = [tex]\sqrt{225}[/tex]

So, x + 3 = 15

Therefore, x = 15 - 3 = 12 ( So, Allison's room has a side of length 12)

Therefore, the carpeting needed = 12 × 12 = 12² = 144 sq. feet

How do you get 60cm2 in question 1?

Answers

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

The 2nd option does not represent a function.

A function is a relation in which no two ordered pairs have the same first component and different second components.

We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)? 

In this case, the answer is no.  The input value of 1 goes with two output values, -1 and -5.   The same goes with the input value of 2, which also goes with two output values: -2 and -4.

It only takes one input value to associate with more than one output value to be invalid as a function.

I also did the Vertical Line Test to show why Option 2 is not a function. The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

However, the graph shows that the two vertical lines crossed the graphed twice (there are 2 points in each line). The graphed points failed the vertical line test. Therefore, Option 2 is NOT a function.

a square has a perimeter of 72 units. if its length measures 3y and its width measures 2x, what is the area of the square

Answers

Answer:

324

Step-by-step explanation:

square has 4 sides.

perimeter adds all sides to make 72

72/4=18 units each side

length * width =area of square

square has all sides equal, so 3y and 2x are tricks to confuse. All sides are 18.

18*18= 324

Richard and Teo have a combined age of 31. Richard is 13 years older than twice​ Teo's age. How old are Richard and​ Teo?

Answers

Answer:Teo is 6 and Richard is 25

Step-by-step explanation:  Let R and T stand for Richard and Teo's ages.  We are told:

R+T=31

R=2T+13

Substitute:  

R+T=31

2T+13+T=31

3T+13=31

3T=18

T=6  

Since R+T=31, R+6=31, and R = 25

Masha bought red, green, and yellow balloons for a party. She bought 40 red balloons. The number of green balloons Masha bought is 3/5 of the number of red balloons. The number of green balloons is also 2/3 of the number of yellow balloons. while being inflated, 1/20 of the red balloons, 1/12 of the green balloons, and 1/36 of the yellows balloons popped. The remaining balloons were used as decoration. What part of all the balloons Masha purchased to decorate the party?

Answers

Answer:

95 balloons

Step-by-step explanation:

red = 40

green- 40x(3/5) = 24

yellow- 24÷(2/3) =36

36× (1/36) = 1. 1 yellow balloon popped

24× (1×12) = 2. 2 green balloons popped

40×(1/20) =2. 2 red balloons popped

40+24+36= 100

2+2+1=5

100-5 = 95 balloons left for decorations

Can someone help me do this

Answers

Answer:

6

Step-by-step explanation:

Find the missing angle:

180⁰ - 82⁰ = 98⁰

Find the sum of the angles given without the missing angle:

180⁰ - 98⁰ = 82⁰

The sum of both the angles is 82⁰

Write an equation:

5x + 8 + 6x + 8 = 82⁰

Collect the like terms together

11x + 16⁰ = 82⁰

Subtract 16⁰ from both sides

11x = 66⁰

Divide by 11 on both sides

x = 6⁰

1.21 rounded to the nearest whole number​

Answers

1.2

1 is the whole number and to round you look one place over, in this case the number one over to the left if 2. If the number to the left is 5 or more you “raise the score” making the number your rounded go up one. If the number is 4 or less, you “let it rest” meaning the number stays the same. Once you round, you drop every number behind the number you used to round. So instead or 1.21 it’s 1.2
