Tyrone went to a basketball game and bought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89. Tyrone spent a total of $83.39. Write an equation to find the original cost of the jersey
Answer:
Jersey cost (without discount)= $65
Step-by-step explanation:
First, we need to determine how much he spent on the jersey:
Jersey cost (with discount)= 83.39 - 37.89
Jersey cost (with discount)= $45.5
Now, the original cost of the jersey:
Jersey cost (without discount)= discount cost / (1 - discount)
Jersey cost (without discount)= 45.5 / 0.7
Jersey cost (without discount)= $65
60,000 is borrowed for 10 years. If the interest on the loan is 49,321.74 , find the monthly payment
Answer:
911.0145
Step-by-step explanation:
60,000 is the initial cost to repay and you add 49,321.74 because of interest
60,000+49,321.74= 109321.74 this is the final cost with interest
you divide by ten because there are ten years and you want it to equal 1 year
109321.74/10= 10932.174 this is the cost per year
last you divide by 12 because thats how many months there are per year
10932.174/12= 911.0145 this is the cost per month

Anna ran 10 meters, Bill ran 15 meters, and Chloe ran 20 meters. How many centimeters did the three people run?
Answer:
Anna: 1000cm
Bill: 1500
Chloe: 2000
convert m to cm
Answer:
4500 cm
Step-by-step explanation:
1 meter = 100 cm
10 meters = 1000 cm
15 meters = 1500 cm
20 meters = 2000 cm
1000 + 1500 + 2000 = 4500 cm

Evaluate 4^0×x^-5 when x=2 .
Answer:
1/32
Step-by-step explanation:
Anything to the power of 0 is 1.
1*x^-5 (negative power means the reciprocal)
1/2^5 = 1/32
1*1/32=1/32
When x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.
To evaluate the expression 4⁰ × x⁻⁵ when x = 2, we'll substitute the value of x into the expression and perform the necessary calculations.
First, let's evaluate 4⁰. Any number raised to the power of 0 is equal to 1. Therefore, 4⁰ = 1.
Next, let's evaluate x⁻⁵ when x = 2. A negative exponent indicates the reciprocal of the base raised to the positive exponent. So, x⁻⁵ = 1 / x⁵.
Substituting x = 2, we have 1 / 2⁵.
Now, we can simplify the expression:
1 / 2⁵ = 1 / 32 = 0.03125
Therefore, when x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.

In a sample of 500 respondents, men account for 20% of all observations in the sample. What is the total number of females in the sample ?
A percentage is a way to describe a part of a whole. The total number of females in the sample are 400.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that In a sample of 500 respondents, men account for 20% of all observations in the sample. Therefore, if we deduct the number of male from the total number of respondents, then we can get the total number of women.
Now, the total number of females in the sample are:
Total number of females in the sample
= Total number of respondents - Total number of males in the sample
= 500 - 20% of total respondents
= 500 - 20% of 500
= 500 - 0.20(500)
= 500 - 100
= 400
Hence, the total number of females in the sample are 400.

A high school reports that its students' SAT scores were down by 8% in one year. The next year, however, the test scores rose by 18%. The high school principal announces, "Overall, test scores have improved by 10% over the past two years."
Answer:
B
1.09 is the improvement in scores
Step-by-step explanation:
Here is the remaining part of the question : Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The statement is true because 18 - 10 = 8 and the percentage improvement is given by the difference in the percentages of the increase and decrease. B. The statement is false because the reference values for the decrease and increase are not the same. The true improvement over the past two years is (Simplify your answer. Type an integer or decimal rounded to the nearest hundredth as needed.)
let a = scores
If scores decreased by 8% last year, scores that year was (100 - 8%) = 92% = 0.92
scores last year = 0.92a
If scores increased by 18%. It means the score this year is 0.92a x 1.18 = 1.086a
Improvement in scores 1.09

Mrs. Brown drove 105 miles in 2.5 hours. What was Mrs. Browns speed in miles per hour?
Answer:
42mph.
Step-by-step explanation:
We know that the formula for miles per hour is.
r = d/t
R is our rate or miles per hour.
D is our distance.
T is our time.
In this case our distance is 105 miles.
And our times is 2.5 hours.
Therefore if we substitute them into our formula:
105mi ÷ 2.5hrs = 42mph

2x2 + 3x + 1 = 0
Answer:
it's false
Step-by-step explanation:
Answer:
x= -1 or x= -1/2
Step-by-step explanation:
x = -1, x = -1/2, Solve for x:
2 x^2 + 3 x + 1 = 0
The left hand side factors into a product with two terms:
(x + 1) (2 x + 1) = 0
Split into two equations:
x + 1 = 0 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x = -1
Divide both sides by 2:
x = -1 or x = -1/2
What is the value of p so that the expression 4(5 + n) is equivalent to 4(n + p) ?
Answer:
5
