10/4= 2.5
5/2.5= 2
2 would be your first answer
32x2.5= 80
80 would be your second answer
Hope this helped
By this equation: d = 4(32), we know what d equals, which means we have the value of d.
d= 4*32
d = 128
Answer:
60 dogs
Step-by-step explanation:
40/8 = 5 dogs per hour
12 x 5 = 60 dogs in 12 hours
The curve is a linear equation.
<h3>
What type of curve is the given equation?</h3>
It is actually a linear equation, meaning that this is a straight line, not a an actual "curve".
To view the "shape" of the curve, you need to graph it.
You could use a program or do it by hand, to do it by hand, you need to evaluate a lot of points of the equation, and then graph them to see the general behavior of the equation.
In this case, I graphed it with a program, and in the image, you can see that this is a linear equation that decreases as the variable increases.

Answers:
- Problem 1) 40 degrees
- Problem 2) 84 degrees
- Problem 3) 110 degrees
===============================================
Explanation:
For these questions, we'll use the inscribed angle theorem. This says that the inscribed angle is half the measure of the arc it cuts off. An inscribed angle is one where the vertex of the angle lies on the circle, as problem 1 indicates.
For problem 1, the arc measure is 80 degrees, so half that is 40. This is the measure of the unknown inscribed angle.
Problem 2 will have us work in reverse to double the inscribed angle 42 to get 84.
-------------------
For problem 3, we need to determine angle DEP. But first, we'll need Thales Theorem which is a special case of the inscribed angle theorem. This theorem states that if you have a semicircle, then any inscribed angle will always be 90 degrees. This is a handy way to form 90 degree angles if all you have is a compass and straightedge.
This all means that angle DEF is a right angle and 90 degrees.
So,
(angle DEP) + (angle PEF) = angle DEF
(angle DEP) + (35) = 90
angle DEP = 90 - 35
angle DEP = 55
The inscribed angle DEP cuts off the arc we want to find. Using the inscribed angle theorem, we double 55 to get 110 which is the measure of minor arc FD.
