Problem: (6.5/2)^2 = ?
I got 42.25 over 4, but its wrong. So I did 6.5 times 6.5(to square it) and got 42.25. Then I did 2 times 2 and got 4. So, the answer would be 42.25 over 4, right?

Answers

Answer 1

Answer:

10.5625 is the answer I got.

Step-by-step explanation:

I used the process PEMDAS for this equation.

(6.5÷2)^2

6.5÷2= 3.25^2

Now you bring down the new quotient and multiply it by itself.

3.25 x 3.25= 10.5625

Answer 2
the answer is 10.56
use pemdas

A triangle has an area of 15. One of its sides has length 10. What is the length of the altitude to that side?

Answers

Answer:

Altitude = 3

Step-by-step explanation:

Given the area of a triangle as 15, with a length of 10:

We can use the following formula for finding the area of a triangle:

Area (A) = ½bh  

Where:

Base (b) = 10

Height (h) or altitude = unknown

Substitute the given values into the formula:

Area (A) = ½bh  

15 = ½(10)h  

15 = 5h

Divide both sides by 5 to solve for h:

[tex]\displaystyle\mathsf{\frac{15}{5}\:=\:\frac{5h}{5} }[/tex]

h = 3

Therefore, the length of the altitude or height of the given triangle is 3.

The fraction of computer and video game players that are 18 years old or more is 3/4.

Step-by-step explanation:

25% → 25/100 → 5/20 (divided by 5) → 1/4 (divided by 5)

18 years old or more: 45% (18 to 49) + 30% (50 or more) → 75% or 3/4

75% → 75/100 → 15/20 (divided by 5) → 3/4 (divided by 5)

When we divide the fractions with the same base then we subtract the exponents:

Y=1/2x+2
The original slope is 2/4 so simplify making 1/2

Answer:

Y = 1/2x + 2

Step-by-step explanation:

First you find (b) or the Y-intercept which is 2 (Y = mx + 2)

Then you do rise over run to find slope. Rise = 1. Run = 2. Slope (m) = 1/2

Now you have your answer Y = 1/2x + 2

We know that Ravi has 124$, but we don’t need how much he spent! So, for the money he’s spent we are using B to represent it. The way I see the expression is:

T is his total after.

The area of the triangle is less than 18 square inches. Select an inequality that represents a

Answers

Answer:

(1/2)(6)(a) < 18

Step-by-step explanation:

We know the formula for the area of a triangle is 1/2 b x h

The base is 6in and the height is a, so the equation is 1/2 6 x a.

The area is less than 18 sq in, so 1/2 x 6 x a < 18

Now, let's solve the inequality.

1/2 6 x a < 18

3 x a < 18

a < 6
