Two quantities are related, as shown in the table:
x y
2 2
4 5
6 8
8 11
Which equation best represents the relationship?
y = 3 over 2 x + 2
y = 3 over 2 x
y = 3 over 2 x − 1
y = 3x + 2
is Y= 3 over 2 x because y add 3 and x add 2
Given the speeds of each runner below, determine who runs the fastest.
Stephanie runs 12 feet per second.
Liz runs 306 feet in 38 seconds.
Will runs 1 mile in 491 seconds.
Brooke runs 851 feet in 1 minute.
Answer:
Brooke
Step-by-step explanation:
We can solve this by figuring out how far each person runs a second
Stephanie runs 12 feet a second so nothing needs to be done here
Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet
Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75
Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18
Brooke obviously runs the furthest in one second and therefore she's the fastest runner

4(2x^3y^4)^4
__________
2(2x^2y^6)^3
simplify and show work
Answer:
Step-by-step explanation:
Note the following: 2^4 = 16; (x^3)^4 = x^12; and (y^4)^4 = y^16
Then your 4(2x^3y^4)^4 becomes 4*16*x^12*y^16

A dinner cost $28.50 which included a 15% tip. How much was the tip?
Explain the answer please
Answer:
Tip: $4.275 = $4.28
Step-by-step explanation:
Use the formula: Tip = Tip% x Bill Total
In this case, the tip is 15% and the total bill is $28.50.
15% = 0.15
28.50 x 0.15 = 4.275
Round 4.275 to the hundredths, which equals 4.27
Answer: $4.28

Find the measure of the exterior angle BRAINLIEST
Answer:
add
(a+10)+2a+44=180
Subtract 44 first so now our equation is
a+10+2a=136
3a+10=136
3a=126
a=42
plug it into 2a since this is our exterior angle
2(42)
=84 degrees

Answer: from top to bottom: 115, 45, 115, 110, 115
Step-by-step explanation: 115 because the remain angle in that triangle is 65. 180-65 is 115. 45 because vertical angles are equal. 115 because 180-65 is 115. 110 because vertical angles are equal. 115 because vertical angles are equal.
Eleanor and Max used two rectangular pieces of plywood, placed end-to-end, to make a long rectangular stage for the school play. One board was 6 feet long, and the other was 6 1/2
feet long. The two pieces of plywood had equal widths. The total area of the stage was 59 3/8
square feet. What was the width of the plywood?
The area is the product of length and width.
.. area = length * width
.. 61 5/8 = (7 +7 1/2) * width
.. (61 5/8)/(14 1/2) = width = 4 1/4 . . . . feet
The plywood was 4 feet 3 inches wide.
_____
A calculator that works with fractions figures this nicely. By hand, you might compute it as
.. 61 5/8 = (8*61 +5)/8 = 493/8
.. 14 1/2 = (2*14 +1)/2 = 29/2
.. (61 5/8)/(14 1/2) = (493/8)/(29/2) = (493/8)*(2/29) = 493/(4*29) = 493/116
.. 493/116 = 4 +29/116 = 4 +29/(4*29) = 4 1/4

Xavier streamed 6 movies for $75 from his cable provider. Write an equation to find the cost, c, of each movie.]
I NEED HELPPPP
Answer:
A: 6c=75 If there were 6 movies then 6 times the cost of each movie would equal 75.
B:$12.50 We divide 75 by 6.
C: d+75=100 the cost left on the card plus 75 will equal 100.
D: $25 We subtract 75 from 100
Hope this helps :)
-ilovejiminssi♡
Answer:
6m = 75
Step-by-step explanation:
To find the cost per movie, we can divide. We can show this by using the equation 6m = 75.
6m/6 = 75/6
m = 12.5 per movie

Step-by-step explanation:
Substitute c for 5 and d for 4

150 - 20 + 8
= 138
In the diagram below, the radii of the two concentric circles are 3 centimeters and 7 centimeters, respectively.
What is the area of the shaded region?
40pi cm2
41pi cm2
8pi cm
80pi cm
Answer: 40 pi cm^2
Step-by-step explanation: the area of a circle is pi*r^2. the shaded region is the area of the large circle minus the area of the small circle. the larger circle has an area of 49pi and the smaller circle has an area of 9pi. 49pi-9pi is 40pi cm^2
Braxton puts $1,275 into a savings account that earns 3% simple interest per year. How much total money will be in his account after 5 years?
A) $191.25
B) $1,466.25
C) $19,125.00
D) $20,400.00
Answer:
The answer would be B) 1,466.25
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I= P x r x t
Where:
P is the principal amount, $1275.00.
r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 1275 × 0.03 × 5 to get that:
The interest is: $191.25
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 1275.00 + 191.25 = 1466.25.
