Answer: C
Step-by-step explanation:
-8p = -3 1/4 The first think you want to do is convert the mixed fraction into an improper fraction.
-8p = -13/4 Now multiply both sides of the equation by 4.
-32p = -13 Divide both sides by -32
p = 13/32
Best answer gets brainiest. Ariel hiked to a famous point with a beautiful view. It took 2 hours and 20 minutes to hike to the viewpoint and 55 minutes to hike back. Ariel spent 1 hour and 40 minutes enjoying the view at the top. She finished the hike at 2:55 P.M. What time did Ariel start the hike to the viewpoint?
Include A.M. or P.M. in your answer.
Answer:
10: 00 AM
Step-by-step explanation:
2 hr 20 minutes +55 min= 3 hours 15 minutes

Find an equation of the line that passes through the point (23, 22) and is
parallel to 2x=3-5y
Answer:
The equation of the line is y= -2/5x+156/5
Step-by-step explanation:
y=mx+b
m= -2/5 ( 23,22)
y-y=m(x-x¹)
y-22=-2/5(x-23)
y-22=-2/5x+46/5
+22 +22
y= -2/5x+156/5

The equation y = 12x represents a proportional relationship. What is the
constant of proportionality? will give brainliest
Answer:
D
Step-by-step explanation:
Proportional relationships come in the form
[tex]y=kx[/tex]
and [tex]k[/tex] is the constant of proportionality. By comparing the general case [tex]y=kx[/tex] and your specific case [tex]y=12x[/tex], you can see that in your case [tex]k=12[/tex].
In the equation y = 12x the constant of proportionality is D. 12.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Let y = kx.
∴ k = y/x.
Given, y = 12x.
12 = y/x.
So, the constant of proportionality is 12.

Find the volume of a pyramid with a square base, where the side length of the base is
14.7 in and the height of the pyramid is 17.2 in. Round your answer to the nearest
tenth of a cubic inch.
Answer:
1238.9
Step-by-step explanation:
The volume of pyramid with square a square base is 1239 [tex]inch^{3}[/tex]
What is pyramid with square base?A three-dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called vertex) is called a square pyramid
We have
Side length of base(L) = 14.7 inch
Height of pyramid(H) = 17.2 inch
Given ,Base is a square then
length=width(w)=14.7 inch
We know the formula of volume of pyramid = 1/3(L×W×H)
= 1/3 (14.7 × 14.7 × 17.2)
= 1/3 × 3716.748
= 1238.916
= 1239 [tex]inch^{3}[/tex]
Hence, The volume of pyramid is 1239 [tex]inch^{3}[/tex]

Hayden plans to take a loan out to buy his Ultimate PC
Gaming Desktop. He will borrow $6,200 from the bank
at a rate of 3.5% annually. The length of the loan will be
5 years. How much interest will Hayden have to pay on
the loan? What is the total that Hayden will have to pay
the bank back?
Give step by step plz
Answer:
The rate of simple interest for loan was 8%
Step-by-step explanation:
Given
Principal amount = p = $6200
Time = t = 1 year
Amount after interest = $6696
We have to calculate the amount of interest first
So,
Interest amount =I= Amount after interest - principal amount
= 6696-6200
=$496

What is an equation parallel to y=3x-5
Answer:
ANY line that has a slope of 3, and any y intercept other than -5.
Step-by-step explanation:
Parallel lines have the same slopes, but different y intercepts.

determine the coordinates
Answer:
Thus, the rule of a point P(x, y) reflected over the line y = -x
P(x, y) → P'(-y, -x)
we conclude that:
A(3, 4) → A'(-4, -3)B(3, 2) → B'(-2, -3)C(-1, 2) → C'(-2, 3)Step-by-step explanation:
We know that If a point P(x, y) is reflected over the line y = -x, the x-coordinate and y-coordinate tend to change places and the signs are reverses.
Thus, the rule of a point P(x, y) reflected over the line y = -x
P(x, y) → P'(-y, -x)
Thus, we conclude that:
A(3, 4) → A'(-4, -3)B(3, 2) → B'(-2, -3)C(-1, 2) → C'(-2, 3)Assume that when adults with smartphones are randomly​ selected, 63​% use them in meetings or classes. If adult smartphone users are randomly​ selected, find the probability that exactly of them use their smartphones in meetings or classes.
Answer:
Solved using binomial, probability = 5.7%
Step-by-step explanation:
Number of people (N) = 7
Probability of success (using phone) = 63% = 0.63
So, probability of failure (not using phone) = 1 - 0.63 = 37
Number of success (r) = 2
N c r . P^r . Q^n-r
7 c 2 (0.63)^2 (0.37)^5
= 21 (0.3969) (0.0069)
= 0.057
