Step-by-step explanation:
an average of $3 per student would mean
sum(all students $) / 45 = 3
sum(all students $) = 3×45 = 135
x students have $5.
therefore (45-x) students have $2.
5x + 2(45-x) = 135
5x + 90 - 2x = 135
3x = 45
x = 15
so, 15 students have $5, and 45-15 = 30 students have $2.

Measure of <2 = 37.3 because opposite sides of a line are congruent. To find < 1, you have to add that plus <2 ( 37.3 ) to equal 180. 180 -37.3 = 142.7
For <3, it is also gonna be 142.7 ( as said before, opposite sides are congruent. ) and for <4, it is gonna be 79.4. Hope this helps! If you have any other questions, let me know! :D
At the beach, nardia collected triple the number of seashells that pierre did. together, they collected 52 seashells. which equations represents p, the number of seashells that pierre collected. 3 p p = 52 3 p = 52 52 p = 3 p 52 p = 3
The equation that represents p, the number of seashells that Pierre collected is 3p + p = 52
Writing a system of equationFrom the question, we are to determine the equation which represents p
From the given information,
Nardia collected triple the number of seashells that Pierre did
If Pierre collected p number of seashells
Then,
Nardia collected 3p number of seashells
Also, from the given information,
They collected 52 seashells in total
That is,
3p + p = 52
Hence, the equation that represents p, the number of seashells that Pierre collected is 3p + p = 52.

The volume of an aquarium is 4,000 cubic feet and has a height of 10 ft. if a similar aquarium has a height of 1 foot, how many cubic feet would the smaller aquarium hold
The volume that the similar aquarium will hold is 400 cubic feet
Similar figuresSimilar figures are figures that have similar angles and sides.
Given the following parameters
volume of aquarium = 4000 cubic feetheight of aquarium = 10feetheight of similar aquarium = 1 feetRequiredVolume of similar aquarium
Substitute into the formula
V/H = v/h
4000/10 = v/1
400 = v
v = 400 cubic feet

What is the slope of the line that represents this relationship?
_______
Graph the line that represents this relationship.
ill attach the table and the graph
The Answer is 10/13 :)
Explanation: (13−0)
= 10/13
(10−0)
13,10
The slope of the line that represents this relationship is 10/13 .
What is the slope of the lineThe graph of the line representing the proportional relationship will be a straight line passing through these two points.
The x-axis represents the "x" values, and the y-axis represents the "y" values. The line should have a positive slope and go through the points (0, 0).
From the graph (13−0) = 10/13
From the graph one can see that (10−0) will lead to the points of 13,10 So, the slope of the line that represents this relationship is 10/13 .

Solve for x.
144°
18 degrees
30 degrees
48 degrees
120 degrees
Answer:
x = 18 °Step-by-step explanation:
you have a rotation angle of 360 °, take out the known values (360 ° -90 ° -144 ° = 126), 144 ° is part of a flat angle of 180 °, from 180 ° remove 144 and you have 36 °, they are opposite angles therefore the same. therefore 360 - 144 - 90 - 36 - 36 = 54.
54 is 3x, so x = 18 ° (54 : 3 = 18)

Answer:
7 1/15 ( mixed number )
Step-by-step explanation:
First, add...
4 + 2 = 6
Then as you can see you can't add when both denominators are not the same so multiply 5 and 3 and you get 15
Then do...
2/5 x 3/3 = 6/15
And...
2/3 x 5/5 = 10/15
Then add...
6/15 + 10/15 = 16/15
But this number is an improper fraction so the mixed number for it is...
1 1/15 + 6 = 7 1/15
So this gives us the final answer of 7 1/15 ( mixed number )

Three straight lines are shown in the diagram.
310°
a
C
38%
87%
Step-by-step explanation:
______________________The sum of angle at a point is 360° so...
310° + a = 360°
a = 360° - 310°
a = 50°
Now...
here b and 180° are supplementary angle so ....
b = 180° - 80°
b = 100°
Again...
The sum of all angle of triangle is 180° so...
100° + 50° + c = 180°
150° + c = 180°
c = 180° - 150°
c = 30°
______________________Hence...the value of a is 50° , b is 100° and c is 30°...

Answer:
A or 2
Step-by-step explanation:
Reason:
The 5's cancel out leaving the 2 behind as the final answer.
Another way to look at it is that the 5*2 up top multiplies to 10, then we divide that by the 5 in the denominator to end up with 10/5 = 2
If you are a visual learner, then draw a circle and divide it into 5 equal slices. Do this a total of five times. Each pizza having 2 slices, and 5 pizzas total, gives 2*5 = 10 slices overall. These ten slices can be rearranged into making 2 full pizzas.

Answer:
1.875
Step-by-step explanation:
the average rate of change of g(x) in the closed interval [ a, b ] is
[tex]\frac{g(b)-g(a)}{b-a}[/tex]
here [a, b ] = [- 1, 3 ] , then
g(b) = g(3) = 2³ + 1 = 8 + 1 = 9
g(a) = g(- 1) = [tex]2^{-1}[/tex] + 1 = [tex]\frac{1}{2}[/tex] + 1 = 1.5
then
average rate of change = [tex]\frac{9-1.5}{3-(-1)}[/tex] = [tex]\frac{7.5}{4}[/tex] = 1.875
solve 3y= x+1 and 2y= x
Answer:
(2, 1 )
Step-by-step explanation:
3y = x + 1 → (1)
2y = x → (2)
substitute 2y = x into (1)
3y = 2y + 1 ( subtract 2y from both sides )
y = 1
substitute y = 1 into either of the 2 equations and solve for x
substituting into (2)
2(1) = x
2 = x
solution is (2, 1 )
Answer:
{y,x} = {-1,-2}
Step-by-step explanation:
2y = - 2
[2] y = - 1
// Plug this in for variable y in equation [1]
[1] 3•(-1) - x = -1
[1] - x = 2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = -1
x = -2
{y,x} = {-1,-2}

The angle of elevation from her eyes to the roof ((point AA)) is 27^{\circ} ∘ , and the angle of elevation from her eyes to the top of the antenna ((point BB)) is 37^{\circ} ∘ . If her eyes are 1.54 meters from the ground, find the height of the antenna ((the distance from point AA to point BB)). Round your answer to the nearest tenth of a meter if necessary.
The answer is 5.1.
