Answer:
Lewis can paint 320 square yards.
Step-by-step explanation:
1 quart covers 80 square yards
8 x 10=80
4 quarts covers 320 square yards
80 x 4=320
Answer:
BC = 25
Step-by-step explanation:
To find the length of BC you need to use the pythagorean theorem.
![a^{2} +b^{2}=c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%3Dc%5E%7B2%7D)
There are two part to a triangle that need to be put into this equation. The hypotenuse(c) and the legs(a, b). The legs would be the side NEXT to the right angle. The hypotenuse is ACROSS from the right angle. In this equation we are looking for the hypotenuse. It doesn't matter which letter the legs replace just remember that the hypotenuse alway has to be C.
![20^{2} +15^{2} =c^{2}](https://tex.z-dn.net/?f=20%5E%7B2%7D%20%2B15%5E%7B2%7D%20%3Dc%5E%7B2%7D)
Now you have to square the numbers then add.
![400+225=c^{2}](https://tex.z-dn.net/?f=400%2B225%3Dc%5E%7B2%7D)
![625=c^{2}](https://tex.z-dn.net/?f=625%3Dc%5E%7B2%7D)
Now find the square root of 625 to get rid of the squared in the C.
c = 25

Answer:
x=10,-10
Step-by-step explanation:
Take the square root of both sides of the equation to eliminate the exponent on the left side
The complete solution is the result of both the positive and negative portions of the solution.
Simplify the right side of the equation
The complete solution is the result of both the positive and negative portions of the solution.
If 15 degrees in 2hrs then in 1hrs is 15(degrees)÷2(hrs) and that is 7.5 degrees
That makes 7.5 degrees per hour

Multiples of 4 are 4,8 and 12
Number of Multiples of 4=9
Therefore:
Probability that the sum of the numbers on the top of both cubes will be a multiple of 4 =9/36
=1/4.
