Answer:
70
40 % of 70 is 28
Step-by-step explanation:
40 percentage of 70 will be 28
To find the number of which 28 is 40%, we can set up the following equation:
40% of x = 28
To solve for x, we divide both sides of the equation by 40% (or 0.40):
x = 28 / 0.40
Evaluating the division:
x = 70
Therefore, 28 is 40% of 70.

Rian is packing toys in boxes. Each box is 3 inches by 4 inches by 6 inches. Each toy takes up 65% of the volume of the box, and the rest of the volume of the box is filled with foam packing beads. What is the volume, in cubic inches, of the foam packing beads used to fill each box
9514 1404 393
Answer:
25.2 in³
Step-by-step explanation:
The volume of the box is ...
V = LWH
V = (3 in)(4 in)(6 in) = 72 in³
__
65% of the box is filled with a toy, so the remaining 100% -65% = 35% is filled with packing beads. The volume of packing beads required is ...
0.35 × 72 in³ = 25.2 in³
25.2 in³ of foam packing beads are used to fill each box.

A sequence is defined by the recursive rule a1 = -16, an = 1.5an-1. What is the fourth term in the sequence?
Answer:
a(4) = 1.5(-36) = -54
Step-by-step explanation:
a(1) = -16 is given.
a(n) = 1.5*a(n-1).
a(2) = 1.5(-16) = -24
a(3) = 1.5(-24) = - 36

a. The third side must be greater than 7 inches
b. The third side must be equal to or greater than 7 inches
c. The third side must be less than 7 inches
d. The third side must be less than or equal to 7 inches
Answer:
In a triangle the sum of any two sides must be greater than the third side. We have 3+4=7 which is less than 8. So this triangle is never true.

What are the solution(s) of -1/2X+4= X+ 1?
O-1 and 8
О 1 and 4
O 2
O 3
Answer:
X = 2
Step-by-step explanation:
-1/2X+4= X+ 1
Add 1/2X to each side
-1/2X+ 1/2 X+4= X+ 1 + 1/2 X
4 = 3/2 X +1
Subtract 1 from each side
4-1 = 3/2 X +1-1
3 = 3/2 X
Multiply each side by 2/3 to isolate x
3 * 2/3 = 3/2 X * 2/3
2 =X

Which of these lengths CANNOT represent the sides of a triangle? {28, 30, 58} {32, 34, 60} {13, 20, 27} {2, 4, 5}
Answer:
[tex]A.\ {28, 30, 58}[/tex]
Step-by-step explanation:
Required
Which of the lengths do not form a triangle
To do this, we make use of triangle inequality theorem which states that.
[tex]a + b > c[/tex]
[tex]b + c > a[/tex]
[tex]a + c > b[/tex]
Where [tex]a,\ b\ and\ c[/tex] are the sides of the triangle.
So, we have:
[tex]A.\ {28, 30, 58}[/tex]
[tex]28 + 30 > 58[/tex] --- False
[tex]58 + 30 > 28[/tex] --- True
[tex]28 + 58 > 30[/tex] --- True
[tex]B.\ {32, 34, 60}[/tex]
[tex]32 + 34 > 60[/tex] -- True
[tex]32 + 60 > 34[/tex] -- True
[tex]34 + 60 > 32[/tex] -- True
[tex]C.\ {13, 20, 27}[/tex]
[tex]13 + 20 > 27[/tex] -- True
[tex]13 + 27 > 20[/tex] -- True
[tex]20 + 27 > 13[/tex] --- True
[tex]D.\ {2, 4, 5}[/tex]
[tex]2 + 4 > 5[/tex] --- True
[tex]2 + 5 > 4[/tex] -- True
[tex]5 + 4 > 2[/tex] --- True

Step-by-step explanation:
When looking at the box plot, we see that the median is 6 (the horizontal line). So, B and D can be ruled out. Next, the values must range from 2 to 11 (the dots). So, C can be ruled out. Therefore, the only answer left is A! To check your work, you can calculate quartiles but it's not necessary.A car traveled 180 kilometers in 3 hours. Which statement best describes the distance traveled by the car per hour?
Answer:
speed= 60km/h
Step-by-step explanation:
Given data
Distance= 180kilometers
Time= 3 hours
We know that the expression for the speed is
Speed= distance/time
Speed= 180/3
Speed= 60 km/h
Hence the answer is speed= 60km/h
Joanna went school supply shopping. She spent $21.45 on notebooks and pencils. Notebooks cost $1.97 each and pencils cost $1.16 each. She bought a total of 15 notebooks and pencils. How many of each did she buy?
A.

B.
3 notebooks; 12 pencils
C.
8 notebooks; 7 pencils
D.
10 notebooks; 5 pencils
Answer:
A) 5 notebooks, 10 pencils
Step-by-step explanation:
n = notebook
p = pencil
1.97n + 1.16p = 21.45
A)✅
1.97(5) + 1.16(10) = 21.45
9.85 + 11.6 = 21.45
21.45 = 21.45
B) ❌
1.97(3) + 1.16(12) = 21.45
5.91 + 13.92 = 21.45

The number of 8-ounce glasses of water Shane drank each day for 12 days is represented in
this histogram.
Glasses of Water Drank
Number of Days
72 3-4 5-6 7-8
Number of 8-ounce Glasses
Based on this histogram, which statement must be true?
A On exactly 2 of these days, Shane drank 1 to 2 glasses of water.
BOn exactly 3 of these days, Shane drank 7 to 8 glasses of water,
C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.
Don exactly 60% of these days, Shane drank 5 to 6 glasses of water
The histogram representing the data is attcwhwd in the picture below.
Answer:
C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.
Step-by-step explanation:
The number of 8 - ounce glasses is represented on the x - axis and the number of days on the y - axis.
From the histogram ;
Shane drank 1 - 2 glasses on exactly 1 day
Shane drank 3 - 4 glasses on exactly 3 days
Shane drank 5 - 6 glasses on exactly 6 day
Total number of days = 12
60% of 12 = 7.2
On exactly 60% of the days, which is 7.2 days, number of glasses drunk isn't covered by the histogram
25% of 12 ; 0.25 * 12 = 3 days
From the histogram, number of glasses consumed is 3 - 4 glasses ; which is the only true statement about the histogram in the options given.
Decide whether the sequence 4,10,20,34,52 ....... is a linear model,
Quadratic model or cubic model.
Answer:
Lineal.
Step-by-step explanation:
To determine if the sequence 4,10,20,34,52 ....... is a linear model, a quadratic model or a cubic model, the following mathematical logical reasoning must be carried out:
4 to 10 = +6
10 to 20 = +10
20 to 34 = +14
34 to 52 = +18
Thus, we can see at a glance that the sequence increases 4 numbers in each digit, adding first 6, then 10, then 14 and so on, with which the next numbers in that sequence should be 74 (+22), 100 ( +26), 130 (+30), 164 (+34), and so on.
Therefore, since there is no quadratic or cubic relationship, the sequence is linear.

Graph the data. Then find and interpret the slope of the line through the points.
Answer:
4. The slope is 1.5 pages per minute
The interpretation is 1.5 pages takes 1 minute to complete
5. The slope is 135 Calorie per mile
The interpretation is 135 calories of energy is required or used in traveling a distance of 1 mile
Step-by-step explanation:
4. The given data are;
Minutes, x; 0, 1, 3, 5
Pages, y; 0, 1.5, 4.5, 7.5
The graph of the data created with MS Excel is included
From the graph, we have;
The slope is given by the rate of change of the y-values to the change in the x-values of the data
∴ Slope = Δy/Δx
[tex]The \ slope =\dfrac{\Delta y }{\Delta x} = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}} = \dfrac{7.5 - 1.5}{5 - 1} = 1.5[/tex]
The slope = 1.5 pages per minute
The interpretation of the slope is that the number of pages completed per minute is 1.5 pages
5. The given data are;
Miles, x; 0, 1, 2, 3
Calories, y; 0, 135, 270, 405
Please find attached the graph of the data created with MS Excel
From the graph, the slope = Δy/Δx = (270 - 135)/(2 - 1) = 135
The slope = 135 Calorie per mile
The interpretation of the slope is it takes 135 calories to complete 1 mile or vice versa.
