Elmer works in a computer store. He is paid a weekly salary $180 and a commission of 4.5% of all sales. One week, he sold $9770 worth of merchandise. How much did Elmer earn that week?
Answer:
$619.65
Step-by-step explanation:
We know that he gets paid 180 a week, but we don't know how much he got from the commission of his sales. To find it, you multiply 9770 by 0.045 (because 0.045 = 4.5%) which you get 439.65. You then add the 180 to get 619.65.
9770 * 0.045 = $439.65
$439.65 + $180 = $619.65
Elmer earned $619.65 in that week.

what is the positive difference between 19&8?
Answer:
11
Step-by-step explanation:
The positive difference between 19 and 8 is 11.
What is positive difference?It is the value which is obtained when the smaller number is subtracted from the bigger number.
For given example,
We need to find the positive difference between 19 and 8.
here, 19 > 8
So, the smaller number = 8
the bigger number = 19
So, the positive difference would be,
19 - 8 = 11
Therefore, the positive difference between 19 and 8 is 11.

Answer:
37
Step-by-step explanation:
The answer must be (a multiple of 2, 3, 4 and 6) + 1, and (a multiple of 5) + 1, because 1 or 2 coins were left over when dividing by 2, 3, 4, 6 or 5.
Let's look at the lowest common multiples of 2, 3, 4, 6:
Prime factorisation:
2 = 2
3 = 3
4 = 2 * 2
6 = 2 * 3
therefore, the lowest common multiple is 2 * 2 * 3 = 12
Let's look at the answers that this would give us (ie multiples of 12):
12 + 1 = 13 <-- this would work, but 11 (ie two less than 13) is not a multiple of 5
12 * 2 + 1 = 25 <-- 23 is not a multiple of 5 either
12 * 3 + 1 = 37 <-- 35 (two less than 37) is a multiple of 5 :)
therefore 37 is our answer since it is one more than a multiple of 12 (ie 36) and two more than a multiple of 5 (ie 35)

A recipe requires 3/4 of a cup of milk for every 1 1/2 cups of flour how many cups of milk are needed for each cup of flour
Answer: 1/2 cup
Step-by-step explanation:
If there are 3/4 cup milk needed for every 1 1/2 cup of flour that means for every 1/2 cup of flour you’ll need 1/4 cup of milk. So for a whole cup of flour you’ll need 2/4 cup of milk which is equivalent to 1/2

455 What is the minimum number of square marbles required to tile a floor of length 6 meter 24
cm. and width 4 meter 16 cm?
A. 6
B. 12
C. 14
D. 8
Answer:
6
Step-by-step explanation:
Length of a floor, l = 6 m 24 cm = 624 cm
Breadth of a floor, b = 4 m 16 cm = 416 cm
We need to find the minimum number of square marbles required to tile the floor.
Taking factors of 624 and 416 by prime factorization :
624 = 2 x 2 x 2 x 2 x 3 x 13
416 = 2 x 2 x 2 x 2 x 2 x 13
Their HCF = 208
No of tiles length wise = 624/208 = 3
No of tiles width wise = 416/208 = 2
The minumum no of tiles needed = 3 × 2 = 6
Hence, 6 square tiles are required to tile a floor.

(a) Which of the following expresses the zero product property formally using quantifiers and variables? ∀ real numbers x and y, if xy = 0 then x = 0 and y = 0. ∀ real numbers x and y, if x = 0 and y = 0 then xy = 0. ∀ real numbers x and y, if x = 0 or y = 0 then xy = 0. ∀ real numbers x and y, if xy = 0 then x = 0 or y = 0. (b) Which of the following is the contrapositive of the zero product property? ∀ real numbers x and y, if x ≠ 0 or y ≠ 0 then xy ≠ 0. ∀ real numbers x and y, if xy ≠ 0 then x ≠ 0 or y ≠ 0. ∀ real numbers x and y, if x ≠ 0 and y ≠ 0 then xy ≠ 0. ∀ real numbers x and y, if xy ≠ 0 then x ≠ 0 and y ≠ 0. (c) Which of the following is an informal version (without quantifier symbols or variables) for the contrapositive of the zero product property? For any two real numbers, if at least one of them is nonzero then their product is nonzero. If the product of two real numbers is nonzero, then both numbers are nonzero. If the product of two real numbers is nonzero, then neither number is zero. If neither of two real numbers is zero, then their product is nonzero.
Answer:
A) ∀ real numbers x and y, if xy = 0 then x = 0 or y = 0.

Answer:
Below in bold.
Step-by-step explanation:
-(s - t) - (s - t)^2 Take out (s - t):
= (s - t)( -1 - (s - t)
= (s - t)(t - s - 1). <---- Factored form.
Or, if you want to expand the expression:
-(s - t) - (s - t)^2
= - s + t - (s^2 - 2st + t^2)
= -s^2 + 2st - t^2 - s + t.

If its -26 degree in Canada and 34 degrees in Australia what is the difference in temperature
Answer:
It would be 60 degrees
Step-by-step explanation:
You take the numbers and write the equation 34-(-26) to figure out the difference. You then change the signs, making it 34+26, as before you were subtracting a negative. If you complete that problem, you come to the conclusion of 60.
