Y=3/8x describes a proportional relationship between x and y. What is the constant of proportionality?
Answer:
The constant of proportionality k is 3/8
Step-by-step explanation:
We are given [tex]y=\frac{3}{8}x[/tex] which describes a proportional relationship between x and y. We need to define constant of proportionality
If y ∝ x then
y=kx where k is constant of proportionality.
Comparing the given [tex]y=\frac{3}{8}x[/tex] with y=kx, we can find value of k i.e constant of proportionality.
So, k= 3/8
Hence, The constant of proportionality k is 3/8

Evaluate the algebraic expression for v= 1 and r = 7
6r - |-8+v|
Answer:
41
Step-by-step explanation:
The absolute value function always gives a positive result, that is
| - a | = | a | = a
Given
6r - | - 8 + v | ← substitute v = 1 and r = 7 into the expression
= 6(7) - | - 8 + 1 |
= 42 - | - 1 |
= 42 - 1
= 41

Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146. Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126.
Given :
Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146.
Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126.
To Find :
The price of each small box and large box.
Solution :
Let, price of small box is x and large box is y.
Mathematical expression of given equations :
11x + 10y = 146 ...1)
5x + 12y = 126 ...2)
Solving above equation, we get :
x = 6 and y = 8
Therefore, price of small and large box is $6 and $8 respectively.
Hence, this is the required solution.

Lisa and Molly are on a bridge and see a tree sticking out of the water. Use the diagram to determine how far away Lisa is from the tree in the water. Use appropriate units.
Answer:
26.5 ft
Step-by-step explanation:
Let the point of the tree sticking out water be represented as S.
Thus, we have ∆LMS.
How far Lisa is from the tree in the water = [tex] \overline{LS} [/tex]
Using Sine Rule, find [tex] \overline{LS} [/tex]
[tex] \frac{\overline{LS}}{sin(M)} = \frac{\overline{MS}}{sin(L)} [/tex]
[tex] \overline{LS} = x [/tex]
[tex] \overline{MS} = 22 ft [/tex]
[tex] \angle M = 103 [/tex]
[tex] \angle L = 54 [/tex]
Plug in the values into the equation
Thus:
[tex] \frac{x}{sin(103)} = \frac{22}{sin(54)} [/tex]
Multiply both sides by sin(103)
[tex] \frac{x}{sin(103)}*sin(103) = \frac{22}{sin(54)}*sin(103) [/tex]
[tex] x = \frac{22*sin(103)}{sin(54)} [/tex]
[tex] x = 26.5 ft [/tex] (nearest tenth)
✅Lisa is 26.5 ft far away from the tree in the water.

What is the volume of a square pyramid that is 60 m on each side of its base and has a height of 100 m round to the nearest 10th
Answer:
Volume of square pyramid=120,000 m³
Step-by-step explanation:
We are given: Base of square pyramid = 60 m
Height of square pyramid = 100 m
We need to find Volume of square pyramid.
The formula used is: [tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h[/tex]
Where a is base and h is height of square pyramid
Putting values in formula and finding volume of square pyramid
[tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h\\Volume \ of \ square \ pyramid=\frac{1}{3}(60)^2(100)\\Volume \ of \ square \ pyramid=\frac{1}{3}(3600)(100)\\Volume \ of \ square \ pyramid=120,000\ m ^3[/tex]
So, Volume of square pyramid=120,000 m³
Solve the following equation. |x| + 8 = 17 A. x = 9 or x = -9 B. x = 25 or x = -25 C. x = 25 or x = -9 D. x = -25 or x = -9
Answer:
a
Step-by-step explanation:
|x| means absolute value.
17-8=9. the absolute value of 9 is 9. (thats why all the negative answers are wrong)
Graph the function. I have provided a picture. First one to answer correctly will get Brainliest
Answer: Draw a straight line through (0, -4) and (2, -1)
Diagram is below
======================================================
Explanation:
The equation is in the form y = mx+b
m = 3/2 = 1.5 is the slope
b = -4 is the y intercept
The y intercept tells us where the graph crosses the y axis. In this case, it happens at (0,b) = (0,-4)
So (0,-4) is one point on the line.
The slope will tell us how to get to another point. Recall that
slope = rise/run
So we see that rise = 3 and run = 2 indicating we'll go up 3 and over to the right 2. Doing that will have you go from (0,-4) to (2,-1)
Therefore, the line will go through the two points (0,-4) and (2,-1) as shown in the diagram below. You can use more points, but two is the minimum number needed to graph a straight line.
---------------------
Another way to get points needed to graph this is to plug in various values of x. Let's say we plug in x = 0
y = (3/2)x - 4
y = (3/2)*0 - 4
y = 0 - 4
y = -4
We see that x = 0 leads to y = -4. So (x,y) = (0,-4) is one point on the line.
If we tried x = 2, then,
y = (3/2)x - 4
y = (3/2)*2 - 4
y = 3 - 4
y = -1
Showing (2,-1) is another point on the line. I didn't pick x = 1 since that would have led to a fractional value. It's easier to work with whole numbers in my opinion.
The football team has a total of jerseys. There are medium-sized jerseys. What percent of the jerseys are medium-sized jerseys? nothing% are medium-sized jerseys. (Type a whole number.)
Answer:
70% are medium-sized jerseys.
Step-by-step explanation:
The complete question is:
The football team has a total of 20 jerseys. There are 14 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys? nothing% are medium-sized jerseys.
Solution:
The information provided is:
The football team has a total of 20 jerseys. There are 14 medium-sized jerseys.Compute the percentage of medium-sized jerseys as follows:
[tex]\text{Medium-sized Jerseys}\%=\frac{n(\text{Medium-sized Jerseys})}{N}\times 100[/tex]
[tex]=\frac{14}{20}\times 100\\\\=70\%[/tex]
Thus, there are 70% medium-sized jerseys.
