Answer:
[tex]\sqrt19[/tex]
Step-by-step explanation:
First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,
9^2 + b^2 = 10^2.
solve, 81 + b^2 = 100
then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].
Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.
4^2 + x^2 = 19.
Solve
16 + x^2 = 19
Subtract 16 from both sides
x^2 = 19
and finally, we take the square root of both sides
x = [tex]\sqrt19[/tex]

Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).
Which point lies on Line UV?
A. ( 7 , 12 )
B. ( 10 , 14 )
C. ( 16 , 22 )
D. ( 20 , 20 )
Answers
Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
[tex]y = mx + c[/tex]
[tex]8 = \frac{3}{4} (4) + c[/tex]
[tex] 8 = 3 + c[/tex]
c is 5
the equation for UV is
[tex]y = \frac{3}{4} x + 5[/tex]
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D

Answer:
y=x-32
Step-by-step explanation:
y=mx+b where m is the slope and b is the y-intercept.
slope=change in y/change in x
=5/5
y=5x+b --> choose a random point
(7,3) ---> 3=5(7)+b=35+b
b= -32
y=x-32

About 71% of Earth’s surface is covered in water.
Question 1
Part A
If Earth's surface area is about 196,900,000 square miles, about how many square miles are covered in water?
Enter the correct answer in the box.
Part B
About what percent of Earth’s surface is not covered in water? How many square miles is this?
Enter the correct answers in the boxes.
Answers
Answer:
A. 139,799,000 square miles
B. 57,101,000 square miles
Step-by-step explanation:
71% ÷ 100 = 0.71
0.71 x 196,900,000 = 139,799,000
100 - 71 = 29
29 ÷ 100 = 0.29
0.29 x 196,900,000 = 57,101,000
another way; knowledge of A
196,900,000 - 139,799,000
= 57,101,000
Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.
Answers
Kenzie can buy 48 Scrunchies
Step-by-step explanation:
You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.
Answer the following questions.
Answers
Answer:
kenzie can only buy 2 sets of scrunchies unless she can buy half then it would be 2.5.
Step-by-step explanation:
20 scrunchies = $3.00 meaning= $3.00+$3.00 = 6 dollars. Anymore would be over the limit of money she would be able to use for the scrunchies.

The Ramirez family has a circular garden with a diameter of 22 feet. They cover the garden with mulch. The cost of mulch is $1.25 per square foot. To the nearest dollar, how much will it cost to cover the garden with mulch. Show your work.
A.$380 B. $475
C. $1.520 D. 1.900
Answers
Answer:
b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has a radius of 11 feet
the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380
Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has
a radius of 11 feet
