100=25*4, so the other side needs to be multiplied by 4. 14*4=56. it's 56.

One more than one-<br>fourth the square of a<br>number x is y

Tatiana [17]

Answer:

y = 1 + ¼x²

Step-by-step explanation:

Given

One more than one-fourth the square of a number x is y

Required

Represent algebraically

We start by analysing the expression one after the other.

First, the two numbers to compare are represented by x and y.

Where y is the resulting number.

So, we start with y =;

Then we move backwards

- "the square of a number, x" can be represented with x²

- one-fourth "the square of a number, x".

The expression in quote has already been represented by x².

So, we can replace this expression with x².

This will give us: one-fourth of x²

One-fourth means ¼

Hence, one-fourth of x² = ¼ * x²

- "One more than" means 1 has to be added to the previous expression to give y.

In other words; 1 + ¼ * x²

Finally, we'll bring the expressions together to give

y = 1 + ¼ * x²

y = 1 + ¼x²

Hence, "One more than one-fourth the square of a number x is y" is represented in algebra by y = 1 + ¼x²

The distance around a circle is 56.55 meters long. What is the diameter of the circle?

yarga [219]

Answer: Diameter of circle = 18m

Explanation:

Given that distance around a circle is = 56.55 meter

The distance around a circle on the other hand is called the circumference .

That means Circumference = 56.55 m

We know the formula of circle's circumference= 2πr

where r is the radius and 2r is diameter of the circle

So,

2πr = 56.55

divide by π both the side

2r = $\frac{56.55*7}{22}$

Value of π = $\frac{22}{7}$

2r = 17.993 ≈ 18 m

Diameter of circle = 18m
