pentagon [3]

Answer:

There are 3000 woman students.

Step-by-step explanation:

Since the ratio is 6:5, so we have to reduce our number to 3000 from 3600 as 6x6=36 and then we can add the zeros.

If you know the diameter of a circle,

arsen [322]

Step-by-step explanation:

a. Area of a circle = πr², where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = $\frac{1}{2}$ diameter.

Step 2: substitute radius into the formula.

Area of a circle = π( $\frac{1}{2}$ d)²

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

Area of a circle = 3.14( $\frac{1}{2}$ d)²

Step 4: substitute d into the formula, then we can solve its area.

b. a. Circumference of a circle = 2πr, where r means radius.

Step 1: converted diameter to radius.

diameter = 2 radius

In other way of writing, radius = $\frac{1}{2}$ diameter.

Step 2: substitute radius into the formula.

C = 2π( $\frac{1}{2}$ d)

Step 3: substitute π into the formula.

some question is given the value of π), if not substitute 3.14 for π.

C = 2(3.14)( $\frac{1}{2}$ d)

Step 4: substitute d into the formula, then we can solve its circumference.

If f(x)=x^2 then what is f(x+h)? an explanation would be lovely, but if not that’s okay :)

Nadusha1986 [10]

Answer: $f(\text{x+h}) = \text{x}^2+2\text{x}\text{h}+\text{h}^2$

====================================================

Work Shown:

$f(\text{x}) = \text{x}^2\\\\f(\text{x+h}) = (\text{x+h})^2\\\\f(\text{x+h}) = (\text{x+h})(\text{x+h})\\\\f(\text{x+h}) = \text{x}*\text{x}+\text{x}*\text{h}+\text{h}*\text{x}+\text{h}*\text{h}\\\\f(\text{x+h}) = \text{x}^2+\text{x}\text{h}+\text{x}\text{h}+\text{h}^2\\\\f(\text{x+h}) = \text{x}^2+2\text{x}\text{h}+\text{h}^2\\\\$

Explanation:

I replaced each copy of x with x+h. Then I used the FOIL rule to expand things out and combine like terms. The distributive property or the box method are two other pathways you can take.

What is -15/16÷7/12= k

Feliz [49]

Solve for k

by simplifying both sides of the equation, then isolating the variable.

Exact Form:

k= −45/28

Decimal Form:

k=−1.60714285…

Mixed Number Form:

k= −1 17/28

so its the top one :)

Andrews [41]

Answer:

product A on machine 1 would make 27 units (rounded down) 81 dollars profit.

product A on machine 2 would make 25 units (rounded down) 75 dollars profit.

product b on machine 1 would make 15 units (rounded down) 75 dollars profit.

product b on machine 2 would make 16 units (rounded down) 80 dollars profit.

Step-by-step explanation:

a1 refers to product a on machine 1

a2 refers to product a on machine 2

same rule applies for product b 1 and 2
