180 degrese or some thing flat
Answer:
the numbers are 4 and 12
Step-by-step explanation:
Given that
x + y = 16 ---------------- eq1
x^2 + y^2 = 160 -------- eq2
From eq1:
x = 16-y
Putting in eq2
(16 - y)^2 + y^2 -160 = 0
256 -32y + y^2 +y^2 - 160 = 0
96 -32y +2y^2 = 0
Taking 2 common:
48 - 16y + y^2 = 0
48 - 12y - 4y +y^2 = 0
12(4 - y) -y(4 - y)= 0
(12 -y) (4 - y) = 0
So weather:
y=4
OR
y = 12
Now put vaules of y in eq1
x + 4 = 16 =====> x = 12
x + 12 = 16=====> x = 4
So the numbers are 4 and 12

Answer:
$375.32
Step-by-step explanation:
100% - 40% = 80%
80/100 = 0.8 (multiplier)
521.28 x 0.8 = 417.024
417.024 to 417.02 (2 d.p.)
100 - 10 = (ans)/100 = 0.9
417.02 x 0.9 = 375.318
$375.32
Answer: {x,y}={-1,2}
step-by-step explanation:
// Solve equation [2] for the variable x
[2] 2x = 5y - 12
[2] x = 5y/2 - 6
// Plug this in for variable x in equation [1]
[1] 2•(5y/2-6) + 3y = 4
[1] 8y = 16
// Solve equation [1] for the variable y
[1] 8y = 16
[1] y = 2
// By now we know this much :
x = 5y/2-6
y = 2
// Use the y value to solve for x
x = (5/2)(2)-6 = -1
Solution :
{x,y} = {-1,2}
I saw the image that should have been included in this problem.
It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.
The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches
volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³ Choice B i believe.
