Before solve this you've to know that,

( + ) × ( - ) = ( - )

( + ) × ( + ) = ( + )

( - ) × ( - ) = ( + )

Let us solve now.

13 + (-7)

13 - 7

= 6

The sides of a square are 2^4/9 inches long. what is the area of the square?

andrey2020 [161]

The area of a square is the length of a side times itself:
2_4/9 * 2_4/9
Mixed numbers cannot be multiplied, so first convert to improper fractions:
(9*2)+4 = 18+4 = 22/9
22/9 * 22/9
Multiply straight across:
(22*22)/(9*9) = 484/81
Now turn this into a mixed number:
81 goes into 484 five times with 79 left over:
5_79/81 square inches
Since this is not one of the answer choices, I'm wondering if the given length of the side of the square is incorrect?

Step-by-step explanation:

$\sin(45) = \frac{x}{5} \\ \frac{1}{ \sqrt{2} } = \frac{x}{5} \\ x = \frac{5}{ \sqrt{2} } = 3.535$

$\sin(45) = \frac{y}{5} \\ y = \frac{5}{ \sqrt{2} } = 3.535$

Part 1) we know that
Volume of rectangular prism=L*W*H-------> 3*6*4-----> 72 units ³
and
Volume of rectangular prism=Area of the base*H
Area of the base B=L*W------> 3*6----> 18 units²
so
Volume of rectangular prism=18*4-----> 72 units³

the answer Part 1) is the option
C) V=Bh

Part 2) we know that
Volume of rectangular prism=L*W*H-------> 5*2*3-----> 30 units ³
and
Volume of rectangular prism=Area of the base*H
Area of the base B=L*W------> 5*2----> 10 units²
so
Volume of rectangular prism=10*3-----> 30 units³

the answer Part 2) is the option
C) V=Bh

Part 3) we know that
Volume of rectangular prism=B*H
B=area of the base--------> 5*3-----> 15 units ²
H=3 units
Volume of rectangular prism=15*3-----> 45 units³
and
Volume of rectangular prism=L*W*H
Volume of rectangular prism=5*3*3-----> 45 units³

the answer Part 3) is the option
C) V=LWH

Part 4) Part 3) we know that
Volume of rectangular prism=B*H
B=area of the base--------> 5*5-----> 25 units ²
H=7 units
Volume of rectangular prism=25*7-----> 175 units³
and
Volume of rectangular prism=L*W*H
Volume of rectangular prism=5*5*7-----> 175 units³

the answer Part 4) is the option
C) V=LWH

Pete is ahead of nick by 11 meters. Oliver is ahead of manny by 10 meters. Oliver is ahead of pete by 5 meters. How far is the r

Leokris [45]

Answer:

The runner in first place is 16 meters ahead of the runner in last place

Step-by-step explanation:

There are 4 boys racing - Pete, Nick, Manny, and Oliver.

Pete is 11 meters ahead of Nick, Oliver is 10 meters ahead of Manny, and Oliver is ahead of Pete by 5 meters.

This means Oliver is ahead of the other three racers, putting him in first place, and Manny is between Nick and Pete.

So in order to find out the distance between the racer in first place (Oliver) and the racer in last place (Nick), add the distance between Oliver and Pete and the distance between Pete and Nick.

Add the distances: 5 + 11

Therefore, the runner in first place (Oliver) is 16 meters ahead of the runner in last place (Nick).
