Final answer:
To find the total number of T-shirts and shorts sold, set up equations using the given information. Solve the equations to find the values of the variables. Therefore, the total number of T-shirts and shorts sold is 200.
Explanation:
To find the total number of T-shirts and shorts sold, let's assign variables to the unknown quantities. Let T represent the number of T-shirts sold and S represent the number of shorts sold.
Given that people bought 4 times as many T-shirts as shorts, we have the equation T = 4S.
Since the total sales were $1,040, we can write another equation: 5T + 6S = 1040.
We can substitute the value of T from the first equation into the second equation to solve for S. Substituting 4S for T, we get 5(4S) + 6S = 1040. Simplifying this equation gives us 20S + 6S = 1040. Combining like terms, we have 26S = 1040. Solving for S, we find that S = 40.
Substituting this value back into the first equation, we can find T: T = 4(40) = 160.
Therefore, the total number of T-shirts and shorts sold is 160 + 40 = 200.
the price for dinner in a resteraunt was $80. The customer paid an addition 7% meals tax and left a $15 tip. how much meals tax did the customer pay?
Final answer:
The customer paid a meal's tax of $5.60 on an $80 dinner, calculated by converting the 7% tax rate to a decimal (0.07) and multiplying it by the cost of the meal.
Explanation:
The question pertains to calculating the meal's tax that the customer paid when the price for dinner at a restaurant was $80 and the meal's tax rate was 7%. To calculate the meal's tax, we need to convert the percentage to a decimal and then multiply it by the total cost of the meal.
To do this:
Convert the percent to a decimal: 7% becomes 0.07.
Multiply this decimal by the cost of the meal: 0.07 × $80 = $5.60.
Therefore, the customer paid $5.60 in meal's tax.

If the sum of three numbers is 144, what is the average of the three numbers?
Final answer:
The average of three numbers that sum to 144 is 48, found by dividing 144 by 3.
Explanation:
The average of three numbers is the sum of those numbers divided by three. In this case, if the sum of three numbers is 144, then the average can be found by dividing 144 by 3. Calculating this, we get the average, which is 48 (144 ÷ 3 = 48). Hence, the average of the three numbers is 48.

Step-by-step explanation:
You're using interior angles
Use the law of cosine: c^2 = a^2 +b^2 - 2ab times cos (C)
h^2 = 8^2 + 10^2 - 2(8)(10) times cos (80) so h = 11.67
11.67 over sin (80) = 8 over sin (S) = 10 over sin (T)
sin -1 ((8 times sin (80)) over 11.67) is equal to S
sin -1 ((10 times sin (80)0 over 11.67)) is equal to T
t over sin (T) = s over sin (S)
t = 10 + x
s = 8 + 18 = 22
10 + x over sin (57.54) = 22 over sin (42.45)
x = 22 times sin (57.54) over sin (42.45) and next to this is -10
the answer of x = 17.50

Jill has a balance of $5,000 on her credit card with an annual interest rate of 15%. To pay off the $5,000 in three years, Jill will have to make a minimum payment of $173.33 per month. To pay off the $5,000 in five years, Jill will have to make a minimum payment of $118.95 per month. How much more does Jill have to pay when the length of the loan changes from 3 years to 5 years? A) $1,239.88 B) $1,957.68 C) $2,137.00 D) $897.12
Answer:
The answer is D) $897.12
Step-by-step explanation:
3 years = 36 months
173.33 * 36 = 6239.88
5 years = 60 months
118.95 * 60 = 7137.00
7137.00 - 6239.88 = 897.12

A circular plate has circumference 21.4 inches. What is the area of this plate? Use 3.14 for pi.
Given a circle with a circumference of 21.4 inches, first calculate the radius using the circumference formula, then use the radius to calculate the circle's area, which results in approximately 36.29 square inches.
Explanation:This question involves determining the area of a circle given its circumference. The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference, r is the radius, and π is a constant (approximated to 3.14). Given that the circumference is 21.4 inches, we can rearrange this formula to find the radius (r = C/2π), giving us a radius of approximately 3.4 inches.
Now, knowing the radius, we can use it to find the area using the formula for the area of a circle, which is A = πr². Plugging in the values, we find that the area is approximately 36.29 square inches.

the greatest common factor gcf of 2 monomiald is 3x^2y. One of the monomials is 3x^4y . Which couod be the other monomial.
The other monomial must have the factors of 3x^2y, with the possibility of having higher powers of y, but not lower, as this would change the GCF. An example of a compatible monomial with 3x^4y is 3x^2y^2.
Explanation:The question is asking for the other monomial given that the greatest common factor (GCF) of two monomials is 3x^2y and one of the monomials is 3x^4y. Since the GCF is the product of the lowest powers of common factors in the monomials, the other monomial must have at least the factors 3, x^2, and y to a certain power. It can have these factors to higher powers as well, but not to lower powers, since it would then alter the GCF.
An example of another monomial that could be paired with 3x^4y is 3x^2y^2, because it has the factors of the given GCF with potentially higher powers, without affecting the GCF. Therefore, any monomial of the form 3x^2y^n (where n is greater than or equal to 1) could be the other monomial.

r. Jones took a survey of college students and found that 60 out of 65 students are liberal arts majors. If a college has 8,943 students, what is the expected number of students who are liberal arts majors?
Here, we need to calculate the expected number of students who are liberal arts major.
It is given that, 60 out of 65 students are liberal arts major.
So, we will calculate the percentage of liberal arts major from the total.
Percentage of liberal arts major = [tex] \frac{Number of liberal arts major}{Total students} [/tex] X 100
Percentage of liberal arts major = [tex] \frac{60}{65} [/tex] X 100
Percentage of liberal arts major = 92.31 %
Now, we will calculate for 8,943 liberal arts majors -
In total students of 8,943, liberal arts majors = 92.31 % X 8,943
In total students of 8,943, liberal arts majors =8,256 students (approximately)

pleassssee help
Answer:
1) Area of ΔABD = Area of ΔACD and
2) Area of ΔABO = Area of ΔCDO
Step-by-step explanation:
1) In the given trapezoid ABCD,
AD || BC
Triangles ΔABD and ΔACD lie on the same base AD and lie between the parallel lines AD and BC.
Hence, they are equal in area.
Therefore, Area of ΔABD = Area of ΔACD.
2) From 1), we have
Ar (ΔABD) = Ar(ΔACD)
Subtract Ar (ΔAOD) from both sides,
Ar (ΔABD) - Ar (ΔAOD) = Ar(ΔACD) - Ar (ΔAOD)
Ar (ΔABO) = Ar (ΔCDO)
