Answer:
Sarah
Step-by-step explanation:
For Sarah
Sarah paid $3.84 for 32 ounces of carrots.
32 ounces = $3.84
1 ounce = x
Cross Multiply
x = $3.84/32
x = $0.12
For Sue
Sue paid $5.20 for 40 ounces of carrots.
40 ounces = $5.20
1 ounce = x
Cross Multiply
x = $5.20/40
x = $0.13
Who paid less per ounce?
Sarah paid less per ounce

Answer:
A is correct
Step-by-step explanation:
In this question, we are concerned with. calculating the diameter of a bubble given the volume of the bubble.
Since we have assumed the bubble to be a perfect sphere, it’s volume V = 4/3 * pi * r^3
Plugging the value of V = 1000cm^3 , we have
1000 = 4/3 * pi * r^3
3000/4pi = r^3
r^3 = 238.732
r = cube foot of 238.732
r = 6.20cm
This is same as 6.2cm
Step-by-step explanation:
this is not an isoceles triangle.
anyway, we need to remember 2 things :
1. the sum of all angles in a triangle is always 180°.
2. the sum of all angles around a single point on a line is 360° (as this point wound be the center of an invisible circle). and as the line cuts this circle in half, the angles on one side of the line around this point is therefore 180°.
so, the internal angle Q is then
180 = 50 + 55 + Q
Q = 180 - 50 - 55 = 180 - 105 = 75°
the exterior angle x at Q is then
180 = Q + x = 75 + x
x = 180 - 75 = 105°
