The Evans family paid $1,800 for a new refrigerator, washer, and dryer. The
refrigerator cost $250 more than the washer. The dryer cost half as much
as the washer. How much did the washer cost?
The cost of the washer based on the total cost of $1,800 of all three items is $442.86
How do represent the cost of the washer?
If we assume that the cost of the washer is x, based on that we can determine the cost of the refrigerator and the dryer while deriving from the cost of the washer as denoted below:
cost of washer=x
The cost of the refrigerator is $250 more than the cost of washer i.e. x+250
cost of dryer=0.5*x
cost of dryer=0.5x
total cost=x+x+250+0.5x
total cost=3.5x+250
total amount spent=1800
1800=3.5x+250
1800-250=3.5x
1550=3.5x
x=1550/3.5
x=$442.86

A restaurant chef made 1 1/8 pints of mushroom soup. Each bowl of soup holds 1/8 of a pint. How many bowls of soup will the chef be able to fill?
Write your answer as a fraction or as a whole or mixed number.
Answer:
9
Step-by-step explanation:
We can determine the number of bowls that can be made by dividing the size of the bowl by the amount of soup. 1 1/8 can be expressed as 8/8 + 1/8, or 9/8. (9/8)/(1/8) = 9. The chef can fill 9 bowls of soup.

In which h is the height.
For this problem, we have that the height is of h = 9.8, hence:
v = 8sqrt(9.8) = 25 feet per second.
The holder was running at a rate of 25 feet per second.
Then, in two seconds, the distance is given as follows:
d = 25 x 2 = 50 feet.
The pole vaulter will run 50 feet in 2 seconds.

Calculate the monthly finance charge for the credit card transaction. Assume that it takes 10 days for a payment to be received and recorded and that the month is 30 days long. (Round your answer to the nearest cent.)
The monthly finance charge for the credit card transaction is $51.70.
We need to calculate the monthly finance charge for the given credit card transaction.
What is a credit card transaction?Credit card transaction means the purchase of goods or obtaining of services or cash against the use of the Credit Card, the Card number or in any manner authorised by the Cardholder for debit to the Credit Card Account or utilising of any services made available to the Cardholder by the Bank from time to time in respect.
Given that, $3,000 balance, 21% rate, 150 payments, average daily method
The particular month in question is 30 days long.
Your balance at the start of the month is $3,000.
Annual interest rate = 21%.
Payment = $150.00
When the payment is made in the month, it reflects on the tax amount you pay on both the average daily balance.
The average daily balance is $3000 from day 1 until day 10 (10 days)
The average daily balance is $2850 from day 11 until day 30 (20 days)
Average daily balance for the month = 10 × 3000 + 20 × 2850
= 87000 / 30
= $2900
Interest charge for the month = (0.21 × 2900× 30) / 365
The interest charge for the month = $50.05 rounded to the nearest penny
The average daily balance is $3000 from day 1 until day 29 (29 days)
The average daily balance is $2850 from day 30 until day 30 (1 day)
Average daily balance for the month = 3000 × 29 + 1 × 2850
= 89850 / 30
= $2995
Interest charge for the month = (0.21 × 2995 × 30) / 365
=51.6945≈$51.70
Therefore, the monthly finance charge for the credit card transaction is $51.70.

Singer A
Singer B
The number of concert shows that singer A and singer B attended will be 41 and 18 shows respectively.
How to illustrate the information?Based on the information, the equation for last year will be:
A = 2B + 5
The number will be illustrated as:
A = B + 23
Therefore, it should be noted that we will equate the expression. This will be:
2B + 5 = B + 23.
Collect like terms
2B - B = 23 - 5
B = 18.
A = 23 + B = 23 + 18 = 41
Therefore, the number of concert shows that singer A and singer B attended will be 41 and 18 shows respectively.

The shadow of a building is 30m long when the angle of elevation of the sun is 56°. Calculate the:
(a) height of the building
(b) length of shadow when the sun is at an angle of 32°.
Answer:
(a) height: 44.5 m
(b) shadow: 71.2 m
Step-by-step explanation:
You want building height and shadow length for angles of elevation 56° and 32°, given the shadow is 30 m when elevation is 56°.
Trig relationThe building height and shadow length are the sides opposite and adjacent (respectively) to the elevation angle in the right triangle that models the geometry. The trig function that relates these sides to the angle is the tangent function:
Tangent = Opposite/Adjacent
Application(a) building height
Using the tangent relation, we have ...
tan(56°) = (height)/(30 m)
height = (30 m)(tan(56°)) ≈ 44.4768 m
The height of the building is about 44.5 meters.
(b) shadow length
Using the same relation with the building height known, we have ...
tan(32°) = (44.4768 m)/(shadow)
shadow = (44.4768 m)/tan(32°) ≈ 71.1778 m
The length of the shadow at an angle of 32° is about 71.2 m.
In a class of 23 learners, the girls were 7 more than the boys. How many boys were in the class
Answer:
8 boys.
Step-by-step explanation:
Lets say b is the number of boys and g is the number of girls.
We know that:
23 = b + g
g = b + 7
So then lets solve for b:
23 = b + g
23 = b + ( b + 7)
Simplify.
23 = 2b + 7
Subtract 7 from both sides to isolate the b.
16 = 2b
Divide both sides by 2.
8 = b
So there are 8 boys in the class.
We can check our work by substituting the value of b into our equation.
23 = b + ( b + 7)
23 = 8 + ( 8 + 7 )
23 = 8 + 15
23 = 23
So therefore our answer is correct.

FIND THE 100TH LINE SEGMENT
CUBE #1 HAS 4 LINES
CUBE #2 HAS 12
CUBE #3 HAS 24
WHATS THE 100TH LINE SEGMENT USING NTH TERM.
PICTURE BELOW!
The 100th line segment by using the nth term of a sequence is equal to 20200.
What is a sequence?A sequence can be defined as a series of real and natural numbers in which each term or list of elements are ordered in a particular order and repetitions are allowed.
Next, we would determine the differences between the terms in this sequence until all the differences are the same:
12 - 4 = 8
24 - 12 = 12
40 - 24 = 16
12 - 8 = 4
16 - 12 = 4
Since the differences are the same, the sequence is a quadratic function and it contains an n² term. Also, the coefficient of n² is one-half of the equal difference. This ultimately implies that, the coefficient of n² is equal to 2.
In order to determine the nth term of this sequence, we would develop a table to model increment:
n 1 2 3 4
2n² 2 8 18 32
Operation +2 +4 +6 +8
Sequence 4 12 24 40
By critically observing the table above, we can logically deduce that the nth term of this sequence is given by:
aₙ = 2n² + 2n
a₁₀₀ = 2(100)² + 2(100)
a₁₀₀ = 2(10000) + 2(100)
a₁₀₀ = 20000 + 200
a₁₀₀ = 20200.
