Answer:
w=10 feet
l=21feet
Step-by-step explanation:
let width be x
p=2l+2w
p=62
so we form the equation
l=1+2x
w=x
2(1+2x)+2(x)=62
2+4x+2x=62
6x=60
x=10feet
w=10feet
l=1+2x
l=21feet
Answer:
398-cent stamp for postage.
Step-by-step explanation:
For one letter, Travis needs 37-cent stamp
For four letters, Travis needs 37-cent stamp x 4 letters
= 148-cent
Again,
For one postcard, he needs 25-cent stamp
For ten postcards, he needs 25-cent stamp x 10 postcards
= 250-cent
Therefore, he will spend = (148-cent + 250-cent) = 398-cent stamp for postage.
Answer:
Average speed is calculated by dividing distance by time (e.g. miles/hour). Okay we're going to talk about average speed, instantaneous speed is the distance that you're covering at a specific time. So 100 kilometers an hour, average speed is the total distance you're going to cover over a period of time.
You are given the equation 36 = 9x² + 4y². You are asked to find the slopes of the asymptotes of the hyperbola. A hyperbola has the following general equation x²/a² + y²/b² = 1. the goal here is to find the slopes of the hyperbolic equation. So divide both sides by 36
36 = 9x² + 4y²
(1/36)[36 = 9x² + 4y²]
1 = x²/4 + y²/9
a² = 4
a = 2
and
b² = 9
b = 3
To find the slope, divide a/b and you will get 2/3.
