To find the answer you have to do 7-3 to find out how many hours there were for the temperature to change.
7-3=4
So it took four hours so you have to do 4 times 2 but since the temperature is dropping you have to do 4 times negative 2 so
4x-2=-8
So then you have to subtract 8 from your original number which is 4, so
4-8=-4
So the ANSWER IS D (-4 degrees F)

A square pyramid with a height of 7 inches has volume of 47.25 cubic inches. Find the side length of the square base

mixas84 [53]

Hello,
Volume of the square pyramid=
1/3×B×h where B represent Base and h represent height

Now, substitute the information that we had from this problem into the formula.
47.25=1/3×B×7
Times 3 from both side
141.75=7B
Divide B from both side
B=20.25 square inches
B=s^2
Square root it to get
s=4.5 inches. As a result, the side length of square base is 4.5 inches. Hope it help!

Find the radius and center of the circle<br> 17+x^2+y^2-8x-6y=0

liq [111]

Answer:

Centre: (4,3)

Radius: 2sqrt(2)

Step-by-step explanation:

h = -8/-2 = 4

k = -6/-2 = 3

4² + 3² - 17 = r²

r² = 8

r = sqrt(8) or 2sqrt(2)

sqrt: square root
