Answer:
1 --- The cyclist's average speed was 18 miles per hour.
2 --- I would travel 280 miles far.
3 --- Your average speed was 52.5 miles per hour.
4 --- You should expect to arrive in Leeds at 11:50 AM.
5 --- The athlete will run 2000 m in 8 minutes and 20 seconds.
6A --- The average speed of the journey is 48 miles per hour.
6B --- It will take him 6 hours and 40 minutes.
Step-by-step explanation:
1) 90 / 5 = 18
2) 70 x 4 = 280
3) 315 / 6 = 52.5
4) 210 / 90 = 2.3333
0.333 = 0:20
9:30 + 2:20 = 11:50
5) 2000 / 4 = 500
500 / 60 = 8.3333
0.3333 = 0:20
8.3333 = 8:20
6A) 0:45 = 0.75
420 / 8.75 = 48
6B) 420 / 63 = 6.666
6.6666 = 6:40

Gechina Galvez shopped at a department store during the end-of-summer sale All luggage was marked down 35 percent. She purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8000, and a tote bag that regularly sells for $39.99. What is the total sale price?
Answer:
The total sale price that Gechina paid was $5,274.71.
Step-by-step explanation:
Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:
100 - 35 = 65
(8,000 + 74.95 + 39.99) x 0.65 = X
8,114.94 x 0.65 = X
5,274.71 = X
Therefore, the total sale price that Gechina paid was $5,274.71.

What single decimal multiplier would you use to increase by 7% followed by a 9% increase?
Answer:
[tex]Digit = 1.1663[/tex]
Step-by-step explanation:
Given
Increase by 7% followed by a 9% increase
Required
Represent by a single decimal
Represent 7% increment by x and 9% increment by y.
Increment by 7% is:
[tex]x = 1 + 7\%[/tex]
Express as decimal
[tex]x = 1 + 0.07[/tex]
[tex]x = 1.07[/tex]
Increment by 9% is:
[tex]y = 1 + 9\%[/tex]
Express as decimal
[tex]y = 1 + 0.09[/tex]
[tex]y = 1.09[/tex]
The single digit is:
[tex]Digit = x * y[/tex]
[tex]Digit = 1.07*1.09[/tex]
[tex]Digit = 1.1663[/tex]

What's the slope of -x+2y=5
Answer:
Slope = (1/2)
Step-by-step explanation:
Rearrange the equation into the y = mx + b format.
-x + 2y = 5
2y = x + 5
y = (1/2)x + (5/2)
m represents slope, which is (1/2) in this question.
Pete read 2/5 of his book on the first day and 1/4 of his book on the second day. What fraction of the book Pete has left to read after two days of reading
=========================================================
Work Shown:
2/5 = 8/20 .... multiply top and bottom by 4
1/4 = 5/20 ..... multiply top and bottom by 5
The fractions 2/5 and 1/4 are equivalent to 8/20 and 5/20 in that order.
These new equivalent fractions add to 8/20+5/20 = (8+5)/20 = 13/20
After two days, Pete has read 13/20 of the book.
This leaves 1 - (13/20) = 20/20 - 13/20 = (20-13)/20 = 7/20 of the book left to be read.
Note how 13/20 + 7/20 = (13+7)/20 = 20/20 = 1

Describe the relationship between base 4 and exponent 3
there are no choices I just need an answer
Answer:
To the power 3 means cube.
Whenever you cube an even number it is a multiple of 8.
Whenever an exponent is used on 4, the number is always a square.
The value of the give exponent is 64.
Given that, the base is 4 and exponent is 3.
What is the exponent?Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.
With the base 4 and exponent 3, we have
4³
= 4×4×4
= 64
Therefore, the value of the give exponent is 64.

The Rivertown city council is attempting to choose one of four sites (A, B, C, or D) as the location for its new emergency facility. After the new emergency facility becomes available for service, the current emergency facility will be shut down. The project manager has estimated the following response times in minutes from each of the proposed sites to the four areas that must be served by the emergency facility.
proposed-site Area-Served
1 2 3 4
A 5.2 4.4 3.6 6.5
B 6.0 7.4 3.4 4.0
C 5.8 5.9 5.9 5.8
D 4.3 4.8 6.5 5.1
The number of emergency runs from the current emergency facility to each of the four areas over the past year is as follows:
Area 1 2 3 4
Number-runs 150 65 175 92
Compute the weighted mean response time from the proposed locations and determine which proposed site should be selected for the new emergency facility.
a. site A
b. site B
c. site C
d. site D
Answer:
SITE A
Step-by-step explanation:
Given :
proposed-site Area-Served
1 2 3 4
A 5.2 4.4 3.6 6.5
B 6.0 7.4 3.4 4.0
C 5.8 5.9 5.9 5.8
D 4.3 4.8 6.5 5.1
Area 1 2 3 4
Number-runs 150 65 175 92
Computing the weighted average for the 4 sites :
Site A:
((150*5.2) + (65*4.4) + (175*3.6) + (92*6.5)) / (150 + 65 + 175 + 92)
= 2294 / 482
= 4.7593
Site B:
((150*6.0) + (65*7.4) + (175*3.4) + (92*4.0)) / (150 + 65 + 175 + 92)
= 2344/ 482
= 4.863
Site C:
((150*5.8) + (65*5.9) + (175*5.9) + (92*5.8)) / (150 + 65 + 175 + 92)
= 2819.6/ 482
= 5.850
Site D:
((150*4.3) + (65*4.8) + (175*6.5) + (92*5.1)) / (150 + 65 + 175 + 92)
= 2563.7/ 482
= 5.319
From the weighted average response time computed for the different sites ;
The best location for the emergency facility would be one with the least average response time; which is SITE A.

Area of a triangle = 1/2 x length x height.
80 = 1/2 x (x+1) (2x-2)
Multiply both sides by 2:
160 = (x+1)(2x-2)
Expand the right side:
160 = 2x^2 -2
Add 2 to both sides:
162 = 2x^2
Divide both sides by 2:
81 = x^2
Take the square root of both sides:
x = 9
Now find the length of the s1des:
(x+1) = 9+1 = 10
2x-2 = 2(9) -2 = 18-2 =16
The shorter side is 10

Mick paid $3.84 in sales tax on an item that cost $64.00 before tax. At that rate, how much would he pay in
sales tax for an item that costs $53.00 before tax? Explain STEP-BY-STEP
Tax rate = tax amount / item cost
Tax rate = 3.84 / 64.00
Tax rate = 0.06 (6%)
Tax amount = item cost x tax rate
Tax amount = 53.00 x 0.06 = $3.18

What is 0.36¯¯¯¯ expressed as a fraction in simplest form
Answer:
I think this is probably late, but the answer is 4/11.
Step-by-step explanation:
0.36363636363 is the first repeating fraction and 36.36363636 is the second repeating fraction, because you multiply it by 100.
When 0.3636363636363 is multiplied by 100, the decimal moves from in front of the number 36 and moves behind it. So the answer is now 36.36363636
You're suppose to subtract those two minus each other, the denominator
the fraction is technically 36/99, but simplified version is 4/11. So the answer is indeed 4/11.
Thanks for your time!
Step-by-step explanation:
Answer:
:0.36 repeating can be expressed as 36/99
Step-by-step explanation:
0.36 is equal to 36100, but you can simplify it further by dividing 36 and 100 by 4 to get 925

-2/3-(-3/4)
Simplify if needed
Answer:
1/12
Step-by-step explanation:
Start by simplifying the fraction's signs:
[tex]-\frac{2}{3} - (- \frac{3}{4} ) = -\frac{2}{3} +\frac{3}{4}[/tex]
Now write both fractions as equivalent fraction with a common denominator of 12:
[tex]-\frac{2}{3} +\frac{3}{4} =-\frac{8}{12} +\frac{9}{12}=\frac{1}{12}[/tex]
If you need to add 5/6 to 5/12
again you need to write the fractions with a common denominator in this case also 12:
[tex]\frac{5}{6} +\frac{5}{12}= \frac{10}{12} +\frac{5}{12}=\frac{15}{12} = \frac{5}{4}[/tex]
in this last step we simplified a common factor of "3" in numerator and denominator to reduce the fraction to 5/4
