The mark up on an item is $3.75. If the mark up is 35%, what was the original price? Round

oksian1 [2.3K]

Answer:

$10.71

Step-by-step explanation:

$\frac{3.75}{y} =\frac{35}{100}$

y × 35 = 3.75 × 100

35y = 375

35y ÷ 35 = 375 ÷ 35

$y=10\frac{5}{7}$

y = 10.7142857143

10.7142857143 round to 10.71

On the road, a bike sign in the shape of an isosceles trapezoid is to be painted. The sign and its dimensions are shown below. W

Oksana_A [137]

Equation

A = (b1 + b2)*h /2

Givens

b1 = 5 feet

b2 = 7 feet

h = 3 feet

Sub and solve

Area = (5 + 7)*3/2

Area = 12*3/2

Area = 36/2

Area = 18 Square feet.

An excursion group of four is to be drawn from among 5 boys and 6 girls.

tresset_1 [31]

Answer:

Because you are recounting people several times. Say for example, let us number those people

{1,2,3,4} for the four girls and {1,2…7} for the boys.

One possible combination by your way is to fix one boy and girl each, say

{1,1} and then choose the remaining people. Let this combination be, for the sake of the example, {1,1,2,2,3}. This is a valid combination.

Now, when you fix another combination of a boy and a girl, say {1,2}, you could get the same combination as before because one the combinations while choosing the three remaining people would be {1,2,3}.

A correct way would be to choose girls and then choose 5− boys for 1≤≤4

So we get ∑4=1(4)(75−)=441

The area of a square is 49 square meters. How long is each side?

OLga [1]

Well if 49 is the area, and you get area by multiplying one side by another side, and its a square so the numbers are going to be the same, so you would be multiplying two of the same numbers. And two of the same numbers that equal 49 is 7.
