Answer:
17) m = 35; n = 110
18) b = 90; c = 80; d = 100
Step-by-step explanation:
17)
2m = 70
m = 35
n + 70 + 70 + n = 360
2n + 140 = 360
2n = 220
n = 110
18)
b - 10 + b + 10 = 180
2b = 180
b = 90
b - 10 = c
90 - 10 = c
c = 80
b + 10 = d
90 + 10 = d
d = 100

Tammy opened a credit card with a 19% simple interest rate to purchase a $879 laptop. If she pays off the laptop in 18 months, how much will she have paid in total?
Answers
Answer:
$1146.216
Step-by-step explanation:
Given data
Principal= $879
Rate= 19%
Time = 18months= 1.6 years
The expression for the simple interest is
A=P(1+rt)
substitute
A=879(1+0.19*1.6)
A= 897(1+0.304)
A= 879*(1.304)
A= $1146.216
Hence the amount to be paid is $1146.216

Machine machine with 140 gallon capacity needs to be filled with water/glycol mixture. Someone has already pump 50 gallons of 60% glycol blend into the machine. How much more glycol must you add an order to get a 50% concentration?
Answers
Answer:
40 gal
Step-by-step explanation:
The capacity of the machine is 140 gallons, and it must be filled.
In a 50% glycol solution, the amount of glycol in 140 gallons of solution is
50% * 140 gallons = 70 gallons.
Once the machine is full with 140 gallons of 50% glycol solution, it will have 70 gallons of glycol.
The machine now has 50 gallons of 60% glycol solution.
60% * 50 gallons = 30 gallons
The machine has now 30 gallons of glycol.
70 gal - 30 gal = 40 gal
You must add another 40 gallons of glycol.
A basketball stadium has 15 ,002 zero seats the lower level has 54 than three times as many seats as the upper level the middle level has 40 more than twice as many seats as the upper level used to solve for x and found that the upper level has 2,502 sears
Answers
Answer:
There are 7456 seats on the lower level and there are 5044 seats on the middle level.
Step-by-step explanation:
Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...
# of seats on the lower level = 3x - 50
# of seats on the lower level = 3(2502) - 50
# of seats on the lower level = 7456
Now we just make the equation for the number of seats on the middle level, and so we get...
# of seats on the middle level = 2x + 40
# of seats on the middle level = 2(2502) + 40
# of seats on the middle level = 5044

5. 79
Step-by-step explanation:
All the angles of the triangle add up to 180°
3. 180-(31+112) = 37°
4. (4x-18)+(8x+7)+(5x+4) = 180
17x-7 = 180
17x = 187
x =11
we have found the x now we need to input it to find m∠z
5x+4
=5×11+4
=59°
5. A straight angle is 180° so if the outside angle is 129 the inside one will be 51°
(2x-3)+(x+9)+51 = 180
3x+57 = 180
3x = 123
x = 41
Now we need to find m∠L
2x-3

A construction company is planning to pour concrete for a driveway. The length of the driveway is 16 feet longer than its width w.
a. Write an expression for the area of the driveway.
b. Find the dimensions of the driveway if it has an area of 260 square feet.
Answers
The length of the driveway is 16 feet longer than its width "w".
Length is "w+16".
-----------------------------
32. Write an expression for the area of the driveway.
Area = w(w+16) = w^2+16w sq. ft.
------------------------------------------
33. Find the dimensions of the driveway if it has an area of 260 square feet.
Solve 260 = w^2+16w
w^2+16w-260 = 0
(w+26)(w-10) = 0
Positive solution:
width = 10 ft
length = 10+16 = 26 ft.

A bag contains 22 coins consisting of quarters and nickels. The total value of the coins is $3.90. How many nickels are in the bag? *
Answers
Answer:
8 Nickels
Step-by-step explanation:
Since a Nickel is worth 5 cents ($0.05)
And a Quarter is worth 25 ($0.25)
and theres 22 coins
8 of those coins would be nickels which would mean we add 8 nickels up
8 x 0.05 = 0.4
then we add the quarters up
14 x 0.25 = 3.5
3.5 + 0.4 = $3.90
