On Monday, a local hamburger shop sold a combined total of 408 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?

Answers

Answer:

I'm pretty sure the answer would be 102

Step-by-step explanation:

you divide 408 by 4 because the cheeseburgers sold 3x as much as the hamburgers.

102 hamburgers sold
306 cheeseburgers sold

h = hamburgers
c = cheeseburgers

c = 3h (number of cheeseburgers sold was three times the number of hamburgers sold)

c + h = 408

Substitute in the fact that c = 3h to the other equation:

3h + h = 408
4h = 408
h = 102

3h = 3(102) = 306

Check the math: 306 + 102 = 408

find the quadratic function for f(x) = ax2 + bx +c and a=1, b=4, c= 3

Answers

Answer:

f(x) = g(x - 3)(x - 5) for some g

f(x) = g(x^2 - 8x + 15)

Substitute (4, -1) for (x, f(x)) and solve for g.

-4 = g(4^2 - 8(4) + 15)

-4 = g(-1)

g = 4

f(x) = 4x^2 - 32x + 60

The sales tax is $2.75, making the total cost $57.75.

Answer:

Step-by-step explanation:

The sales tax rate is 5%.  Writing that as a decimal, you have 5% = 0.05 (5 hundredths).

To find the amount of tax, multiply the price by 0.05.

0.05 x 55 = 2.75

The sales tax is $2.75.

The total cost of the shirt ("total" is a clue word) is the price + tax

$55.00 + $2.75 = $57.75

How do you find Median? I completely forgot

Answers

Answer:

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Step-by-step explanation:


To find the median, put all numbers into ascending order and work into the middle by crossing off numbers at each end. If there are a lot of items of data, add 1 to the number of items of data and then divide by 2 to find which item of data will be the median.

Samuel has an ant farm with a volume of 375 cubic inches. The width of the ant farm is 2.5 inches and the length is 15 inches. What is the height of Samuel's ant farm?

Answers

Answer:

Step-by-step explanation:

From the given information, it is clear that the shape of ant form is rectangular prism.

Let us write formula for volume of rectangular prism (ant form)

V = l x w x h

Use the formula to write an equation.

Plug V = 375, w = 2.5 and l = 15

375 = 15 x 2.5 x h

375 = 37.5 x h

Divide both sides of the equation by 37.5

375/37.5 = (37.5 x h)/37.5

10 = h

Hence, the height of the form is 10 inches.
