Answer:

39.375 : 65.625

Step-by-step explanation:

The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.

3/8 × 105 = 39 3/8

5/8 × 105 = 65 5/8

The divided quantities are ...

39.375 : 65.625

I would pick the third choice because in order to find x, you must multipy your 4.

A metal stud for a warrior costume is in the shape of a square pyramid. The stud does not have a base.

bonufazy [111]

The amount of metal needed to make the metal stud for the costume is 12 unit²

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that the meatal stud does not have a base, hence:

Amount of metal needed = sum of area of triangular faces = 4(1/2 * 2 * 3) = 12 unit²

The amount of metal needed to make the metal stud for the costume is 12 unit²

Wilma is 5 times as old as yvonne. in ten years, yvonne's age will be a third of wilma's age. how old are they now?

SVEN [57.7K]

Using a system of equations, it is found that Wilma is 50 years old and Yvonne is 10 years old.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given as follows:

Variable x: Wilma's age.

Variable y: Yvonne's age.

Wilma is 5 times as old as yvonne, hence:

x = 5y.

In ten years, yvonne's age will be a third of wilma's age, hence:

$y + 10 = \frac{1}{3}(x + 10)$

Since x = 5y:

$y + 10 = \frac{1}{3}(x + 10)$

$y + 10 = \frac{1}{3}(5y + 10)$

3y + 30 = 5y + 10

2y = 20.

y = 10.

Then:

x = 5y = 5 x 10 = 50.

Wilma is 50 years old and Yvonne is 10 years old.
