Answer:
33.5
Step-by-step explanation:
let original temperature be T
If after 1 hr temperature drops by 11, then the rate of temperature drop is 11 per hr.
After 4 hours, temperature will drop to 4(T-11).
if temperature after 4 hrs is 90, then
4(T-11)=90
T-11=90/4
T=(90/4) + 11
T=33.5
A, The answer is provided: R=35x
b. R=C when you break even (i.e. your cost equal your revenue)
35x=15x+2000; 20x=2000; x=2000/20; x = 100 rides
They are both acute since they are small angles rather than having a bigger angle
The two similar triangles are triangle BXY and triangle BAC. Since line XY is parallel to segment AC, angle BXY is congruent to angle A, and angle BYX is congruent to angle C. Since two corresponding angles are congruent, we use one of our similarity conjectures, Angle-Angle, to show these triangles are congruent.

The correct representation of the inequality –3(2x – 5) < 5(2 – x) is -6x + 15 < 10 - 5x. It an open circle is at 5 and a bold line starts at 5 and is pointing to the right.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the inequality:
–3(2x – 5) < 5(2 – x)
= -6x + 15 < 10 - 5x
= -x < -5
= x > 5
The correct representation of the inequality –3(2x – 5) < 5(2 – x) is -6x + 15 < 10 - 5x. It an open circle is at 5 and a bold line starts at 5 and is pointing to the right.
