First subtract the number that did, to find the number that didn't.
1300 - 520 = 780 customers did not order coffee.
Now divide the number who didn't order coffee by total number of customers:
780 / 1300 = 0.6
Multiply by 100 to get the percent:
0.6 x 100 = 60% did not order coffee.
Answer:
y = 10
Step-by-step explanation:
Given the 2 equations
y = - 2x + 4 → (1)
y = x² + 4x + 13 → (2)
Since both equations express y in terms of x we can equate them
x² + 4x + 3 = - 2x + 4 ( subtract - 2x + 4 from both sides )
x² + 6x + 9 = 0 ← in standard form
(x + 3)² = 0 ← in factored form
x + 3 = 0 ⇒ x = - 3 with multiplicity 2
Substitute x = - 3 into (1)
y = 6 + 4 = 10

Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
Answer:
4
Step-by-step explanation:
ratio of leg to hypotenuse in a 45-45-90° triangle is 1 :
we can use this proportion to solve the problem:
let 'x' = leg
x/8 = 1/
cross-multiply:
x = 8
x = 8 /
if you multiply top and bottom by you will get 4
