The angle 53° is half the difference of the intercepted arcs, so is
53 = (180 - y)/2
106 = 180 - y
y = 180 - 106 = 74

The bells are adding a new room to their house. The room will be a cube with volume of 5,832 ft^3. They are going to put in hard

gtnhenbr [62]

1620 because 5832 is 18 to the 3rd power which means that because it is a cube 18 to the second power will be able to find the base which 324 ft^2, multiplying that by 5 dollar gets 1,620 dollars

Tammy figured her math exam would be difficult unless she put in at

Ludmilka [50]

Answer: No, she did not study for at least 15 hours.

=======================================================

Explanation:

Fractions are often a pain, so I find it easier to convert to decimal form whenever possible.

1/2 = 0.5

3/4 = 0.75

which lead to,

2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

-----------------------------

We can then rephrase the problem like so:

"She studied 2.5 hours on Monday, 3 hours on Tuesday, 4.75 hours on Wednesday, and 4.5 hours on Thursday"

Add up those decimal values to get:

2.5 + 3 + 4.75 + 4.5 = 14.75

In total, Tammy studied for 14.75 hours, which is equivalent to 14 & 3/4 hours.

This result is smaller than 15, so she did <u>not</u> study for at least 15 hours.

Note: "at least 15" is the same as saying "15 or more".

Find scale factor, solve for x, and solve for y.

snow_tiger [21]

Answer:

Part 1) The scale factor is 3

Part 2) The value of x is 36 in

Part 3) The value of y is 26 in

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Let

z-----> the scale factor

$z=(10+5)/5=3$

step 2

Find the value of x

To find the value of x, multiply the length of 12 by the scale factor

$x=(12)(3)=36\ in$

step 3

Find the value of y

we know that

$(13)(3)=13+y$

$y=39-13=26\ in$
