Suppose a slice of a 10-inch pizza has an area of 15 square inches. What is the angle of this slice?

1 answer:

8 0

Angleslice/360 times area=area of slice

area=pir^2
normally pizzas are given in terms of ther diameter
so 10=diameter
d/2=r, 10/2=5
r=5
area=pi5^2=25pi

angleslize/360 times 25pi=15
do math
times 360 both sides and divide by 25pi both sides
angle=68.7549 degrees or 1.2 radians

The question is actually a financial banking question if it is about his check and how much it was worth statistics would be a couple of other things into a group and ranked. Financial is money.

Answer:

$y=-\frac{3}{2}x+1$

Step-by-step explanation:

Slope-intercept form means

$y=mx+c$

where m is given its the slope which is $-\frac{3}{2}$ and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,

$y=mx+c$

$-5 = -\frac{3}{2}(4)+c$

$-5=-6+c$

$c=1$

now we know the value of slope which is given $-\frac{3}{2}$ and we found the value of which is 1 so we put these values into our original slope-intercept form equation

$y=mx+c\\\\y=-\frac{3}{2}x+1$
