Answer: 7 1/30
Step-by-step explanation:
Tina loves to read. Before breakfast, she read 2 1/2 pages, at lunch she read 3 1/5 pages, and after dinner she read 1 1/3 pages. To find the total, we add all the pages together. This will be:
2 1/2 + 3 1/5 + 1 1/3
The LCM of 2, 5 and 3 is 30.
= 2 15/30 + 3 6/30 + 1 10/30
= 6 31/30
= 7 1/30.
4/7 - -3/5 step by step pls explain
Answer:
41/35
Step-by-step explanation:
Simplify the following:
4/7 + 3/5
Put 4/7 + 3/5 over the common denominator 35. 4/7 + 3/5 = (5×4)/35 + (7×3)/35:
(5×4)/35 + (7×3)/35
5×4 = 20:
20/35 + (7×3)/35
7×3 = 21:
20/35 + 21/35
20/35 + 21/35 = (20 + 21)/35:
(20 + 21)/35

When the large prism was reduced, the surface area changed by a factor of:
Answer: 16/25
Step-by-step explanation:
Answer:
The answer is 16/25
Step-by-step explanation:
Since the original scale factor was 4/5 then you would need to square four and five in order to get the new scale factor.
When you square 4 you get 16 and when you square 5 you get 25. Therefore the answer should be 16/25.

Omar is participating in a -day cross-country biking challenge. He biked for 67,60 ,69 ,68 , and 70 miles on the first five days. How many miles does he need to bike on the last day so that his average (mean) is 67 miles per day?
Answer:
68 miles
Step-by-step explanation:
Distance biked on the first five days =67,60 ,69 ,68 , and 70 miles
Let the distance biked on the sixth day=x miles
We want his average for the 6 days =67 miles per day
Therefore:
[tex]Average=\dfrac{67+60+69+68+70+x}{6} \\67=\dfrac{334+x}{6}\\$Cross multiply\\67*6=334+x\\402=334+x\\x=402-334\\x=68 miles[/tex]
He needs to bike 68 miles on the sixth day to get an average of 67 miles per day/

What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
From the box plot,
We can see that,
Median = 6

The restrooms for the former Estabrook Hall were known to each be 117 cubic feet in volume. We are tasked with creating a 1:4 scale model of one of the rooms. For the purposes of this analysis, we'll treat the facilities like simple rectangular boxes. What is the volume of the model in cubic inches? If the model has a floor area of 117 sq. Inches, what is the height of the real facility? (include units with answer)
Answer:
1) The volume of the model is 3159 in.³
2) The height of the real facility is 61.94 ft
Step-by-step explanation:
1) The parameters given are;
Volume of the Estabrook hall = 117 ft³
Scale of model = 1:4
For the scale factor of a volume, we have;
[tex]Volume \, scale \, factor =\left (\frac{a}{b} \right )^3 = \left (\frac{1}{4} \right )^3 = \frac{1}{64}[/tex]
That is the volume of the model is 1/64 times the volume of the actual Estabrook hall restrooms or
[tex]\frac{1}{64} \times 117 \, ft^3= 1\tfrac{53}{64} \, ft^3[/tex]
∴ The volume of the model = 1.83 ft.³
1 ft.³ = 1728 in.³
∴ 1.83 ft.³ = 1.83 ft.³ × 1728 in.³/ft.³ = 3159 in.³
2) Where the model of the floor has an area of 117 in.²
Therefore, since the volume of a rectangular prism shape = Floor area × Height, we have
The height, h = Volume/(floor area) = 3159/117 = 185.8 in.
From a scale of 1:4, we have that the height of the real facility = 4 × 185.8 in.
Hence, the height of the real facility = 743.3 in = 61.94 ft.
Tia types 66 words in 3 minutes. She wants to know how many words she can type in 5 and 10 minutes if she keeps the same rate.
Answer:
110 words in 5 min, 220 words in 10 min
Step-by-step explanation:
y = mx (there is no intercept because you can't type anything in 0 minutes)
66 = 3m
m = 22
y = 22x
5 minutes:
y = 22(5) = 110 words
10 minutes:
y = 22(10) = 220 words

Vanessa purchased a smart TV for
$1,500 on a payment plan. Four
months after purchasing the TV, her
balance was $1,200. Seven months
after purchasing the TV, her
balance was $975. Find an equation
that models the balance y after t
months. How many months will it
take her to pay off the TV loan?
Answer:
y = 1500 - 75t
It will take her 20 months to pay off her TV loan.
Step-by-step explanation:
Vanessa purchased a smart TV for $1500 on a payment plan. After 4 months of purchasing the TV her balance was $1200 . 7 month her balance was $975. The amount she pays every month can be calculated as follows. After 4 months she paid 1500 - 1200 = $300. Her balance is $1200. Divide 300 by 4 to get $75 per month as the amount she pays every month.
1500 - 975 = 525/7 = $75 per month.
The equation to model the balance y after t months can be expressed below.
y = 1500 - 75t
where
y = balance
t = number of months
Her balance should be $0 for her to be able to pay off the TV loan.
y = 0
-1500 = -75t
divide both sides by -75
t = -1500/-75
t = 20
It will take her 20 months to pay off her TV loan.

What is the correct equation for the line in slope-intercept form?
Answer:
y=-5x+35
Step-by-step explanation:
The equation for a line in slope intercept form is y=mx+b, where m is the slope of the line and b is the y intercept, or where the line meets the y axis.
First, we should calculate the slope of the line. The slope of any line is rise over run. We can select any two points- I will select (6,5) and (4, 15).
We see that the rise is 10 units, because 15-5=10, and the run is -2 units, because 4-6=-2. We have rise over run which is 10/-2, or -5.
So, we find that the m value is equal to -5.
The y intercept is easier to find, it is just where the line meets the y axis. The lines meets the y axis at the point (0,35) so the y intercept is 35.
Thus we have the equation of the line is y=-5x+35.
