Answer: 20

Step-by-step explanation:

40/2 = 20

140/7 = 20

also if you look at the middle of 0 and 2 and go up to where the line is, its between 40 and 0 so its 20.

Jocelyn was asked to draw a square with an area of 20 cm2. Which could be the side length of the square? I. 20 cm II. 5 cm III.

Paladinen [302]

Answer:

The correct option is III: 4.5 cm.

Step-by-step explanation:

The area of a square is the following:

$A = b^{2}$ (1)

Where:

A: is the area

b: is the side of the square

We have that the area is 20 cm², hence by solving equation (1) for <em>b</em> we can find the side:

$b = \sqrt{A} = \sqrt{20 cm^{2}} = 4.5 cm$

Therefore, the correct option is III: 4.5 cm.

I hope it helps you!

Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant o

maria [59]

Answer:

Part 1) The equation is $h=42y$

Part 2) The number of hats Paula can knit is 42 per yard of yarn

Part 3) see the procedure

Part 4) For 378 yards of yarn Paula can knit 9 hats

Step-by-step explanation:

Let

h -----> the number of hats

y ----> the amount of yarn in yards

k ---> constant of proportionality

Part 1) Write an equation to represent the relationship between the numbers of yards of yarn Paula has and the number of hats she can knit

we know that

A relationship between two variables, h, and y, represent a proportional variation if it can be expressed in the form $h/y=k$ or $h=ky$

we have

$k=42$

substitute

$h=42y$

Part 2) What does the constant if proportionality 42, represent in this problem?

The constant of proportionality represent the slope of the linear equation

The value of the slope is $42\ \frac{hats}{yd}$

That means that the number of hats Paula can knit is 42 per yard of yarn

Part 3) Complete the table showing the yards of yarn and the number of hats Paula can knit

we have

$h=42y$

Part a) For y=0 yd Find the value of h

substitute in the linear equation the value of y and solve for h

$h=42(0)=0\ hats$

Part b) For h=3 hats Find the value of y

substitute in the linear equation the value of h and solve for y

$3=42y$

$y=3/42\ yd$ ----> $y=1/14\ yd$

Part c) For y=210 yd Find the value of h

substitute in the linear equation the value of y and solve for h

$h=42(210)=8,820\ hats$

Part d) For y=378 yd Find the value of h

substitute in the linear equation the value of y and solve for h

$h=42(378)=15,876\ hats$

Part 3) For h=11 hats Find the value of y

substitute in the linear equation the value of h and solve for y

$11=42y$

$y=11/42\ yd$

Part 4) Interpret the meaning of the point (378,9)

we have that

y=378 yd

h=9 hats

That means -----> For 378 yards of yarn Paula can knit 9 hats

Plzzzzz help will Mark BRAINLYLIST!!!!!

Serga [27]

Answer:

104 units

Step-by-step explanation:

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.

$AB=\\BC=20\\CD=30\\AD=$

$A'B'=22\\B'C'=\\C'D'=\\A'D'=32$

Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:

$AB=22\\BC=20\\CD=30\\AD=32$

$A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32$

See? Notice how the values are the same! To find the perimeter ( $P$ ) of a quadrilateral, we have to add each side length:

$P=22+20+30+32$

Solve:

$P=104$
