What does Sam need to score on the fourth test to ensure that she will have an
average of 90% for all four tests?
%
Answers
Answer:
98%.
Step-by-step explanation:
The following data were obtained from the question:
Test 1 (T₁) = 83%
Test 2 (T₂) = 91%
Test 3 (T₃) = 88%
Test 4 (T₄) =?
AVERAGE = 90%
We can obtain the score of 4th test by doing the following:
AVERAGE = (T₁ + T₂ + T₃ + T₄) /4
90 = (83 + 91 + 88 + T₄) /4
90 = (262 + T₄) /4
Cross multiply
90 × 4 = 262 + T₄
360 = 262 + T₄
Collect like terms
360 – 262 = T₄
T₄ = 98%
Therefore, Sam need to score 98% in the 4th test in order to have an average score of 90%.

A video game costs $54 dollars after it is released. Every two years, retailers lower the price by multiplying it by 2/3.
Therefore, the cost of the video game after 6 years is,
Cost of video game after 6 years = $54 × (2/3)³ = $16
Hence, the video game cost after six years is $16.

1. Which is an equation of the line parallel to y =2x-7 and passes through
(-1, 3)?
Answers
Answer: The answer is y=2x+5
Answer:
(-3.5,-7)
Step-by-step explanation:
I don't know if this is right or not but in that equation you have to first find what x is. so you would change the equation to look like 2x+y= -7. then you would write 2x+y×0= -7. then the equation would be 2x= -7 and then you would divide 2x÷2=x and -7÷2= -3.5. so for x it would be (-3.5,Y) no we have to figure out y.
so you would keep the equation as 2x+y= -7. and then would write 2x×0+y= -7. and then you would have the equation y= -7. so y= -7.
so if you fill in the spaces you get (-3.5,-7)
sorry if this is incorrect

Miamor wanted to make note cards by cutting pieces of paper in half.
Before starting she got seven more pieces to use. When she was done she
had 28 half pieces of paper. With how many full pieces did she start?
Answers
Answer: 14 pieces
Step-by-step explanation:
Let the number of pieces of paper she had at first be x.
Before starting she got seven more pieces to use. This can be written as:
= x + 7
When she was done she had 28 half pieces of paper. This can then be written as:
x + 7 = (28 × 1/2)
x + 7 = 14
x = 14 - 7
x = 7
Since x = 7, she started with:
= x + 7
= 7 + 7
= 14 pieces

Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept
1. Points are:
(2, -4) and (4, -2)Slope is:
m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1y-intercept is - 6 as per graph
Then the formula is
y = x - 62. Points are:
(0,5 ) and (4, 1)Slope is:
m = (1 - 5)/(4 - 0) = -4/4 = -1y-intercept is 5 as per point
Then the formula is
y = -x + 53. Points are:
(-3, 1), (-1, -3)Slope is
m = (3 - 1)/(-1 -(-3)) = 2/2 = 1y-intercept is -5 as per graph
Then the formula is
y = x - 5(2x^4 + 3x^3 – 5x - 19)+(x^2 + 1)

1. Becky won $108,000 by coming in first place at a chess tournament, and she has the option of receiving 4 quarterly payments of $27,000, with the first payment in 3 months, or 1 lump-sum payment of $108,000 occurring in 12 months. Once she receives her money, she plans on putting it in a savings account paying simple interest at an annual interest rate of 8.8% calculated quarterly. Becky's financial adviser told her that she'll "lose" money if she takes the lump-sum payment, and Becky wants to calculate how much she’ll "lose". HELP !! I don’t understand ! please show work
Answers
Answer:
Step-by-step explanation:
From the information being provided;
We learnt that Becky pays simple interest at an annual interest rate of 8.8% which is calculated quarterly.
i.e. [tex]\dfrac{8.8\%}{4}= 2.2\%[/tex]
Since the first payment of $27,000 happened in the first three months, therefore, Becky will be able to have the money in the bank for 3 quarters prior to the lump-sum payment gets started.
Thus, the estimate of the amount Becky would earn as interest during this period of time is as follows:
[tex]I =\dfrac{PRT}{100}[/tex]
[tex]I =\dfrac{27000\times 2.2 \times 3}{100}[/tex]
[tex]I =\dfrac{178200}{100}[/tex]
I = $1,782
