There is one shaded part out of four parts. This means that the shaded part takes up one-fourth of the overall box, or 1/4. To convert fractions to decimal, you need the denominator to be 100: therefore you multiply 25 to the numerator and denominator: 25/100. This is equal to 0.25 or 25%. The answer is B.
Answer:
B.
Step-by-step explanation:
¼ = 1÷4=0.25
0.25×100=25%

Use the graph that shows the number of laps completed over time. Find the slope of the line.
By using the given graph, we will see that the slope of the linear equation is:
a = 0.5 laps per minute.
How to find the slope of the line?
For a linear equation:
y = a*x + b
Where a is the slope and b is the y-intercept.
We know that if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁).
So we need to look at the graph and identify two points, we will use:
(10 min, 5) and (20 min, 10)
So the slope is:
a = (10 - 5)/(20 min - 10 min) = 0.5 laps per minute.

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 2 intermediate stops on the way to New York and 3 intermediate stops on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

A)
(-3)(-9)
B
(-6) (4)
-4-5
D)
-7-9
Answer:
[B] (-6)(4)
[C] -4 -5
[D] - 7 -9
Step-by-step explanation:
Note that: {Only with ()}
Negative + Negative = Positive
Negative + Positive = Negative
Positive + Positive = Positive
Hence,
[A] (-3)(-9) =27 Negative + Negative = Positive
[B] (-6)(4) = -24 Negative + Positive = Negative
[C] -4-5 = -9
[D] -7-9 = -16
Thus, the answer is
[B] (-6)(4)
[C] -4 -5
[D] - 7 -9

Consider the information about the number of customers that select various frame
colors at a frame store one day.
• 15 customers select white frames.
• 30 customers select black frames.
• 45 customers select gold frames.
Part A
If there are a total of 2.200 customers that order from the frame store one month, what
is the best approximation for how many customers that month select a black frame?
A. 367 customers
B. 733 customers
C. 1, 100 customers
D. 1. 167 customers
Answer:
B. 733 customers
Step-by-step explanation:
15+30+45=90
since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)
Find parametric equations for the sphere centered at the origin and with radius 3. Use the parameters s and t in your answer. x(s, t) = y(s, t) = , and z(s, t) = , where |
Answer:
Step-by-step explanation:
In general (x, y, z) = (p ·cos s ·sin t, p· sin s· sin t, p · cos t) where p is radius
x(s, t)= 3 ·cos s ·sin t
y(s, t)= 3· sin s· sin t
z(s, t) = 3· cos t
Where, radius is 3, s ∈ [0,2π), and t ∈ [0, π]
