To answer the problem above, we first need to know the difference in hours.
from month 1 to 2 the difference in hour is 1.5.
Month 2 to 3 = 3.5 to 5 = 1.5
Month 3 to 4 = 5 to 6.5 = 1.5
Month 4 to 5 = 6.5 to 8 = 1.5
The answer is C. Linearly, because the table shows that hours increase by an equal factor for an equal increase in months. which is 1.5 hours per month.
Answer:
u transpose all the constans to one side of the '=' sign and solve
Step-by-step explanation:
for example,
in the first question
the sides of the triangles are proportional then,
25/30 = x/ 10
=> (25x10)/30 = x
=> 250/30 = x
=> 8.33
im pretty sure like this u can do the rest, ;)
So this is a proportion. The scale is 9 inches tall and the real is 30 feet. First, multiply feet by twelve to find inches.
So the real item is 360 inches tall. So the proportion is 9:360. Or 1:40. The scale is 1/40 the size of the real item. Or the real item is 40 times the size of the scale.
So if the scale drawing is 21 inches long, that means the real item is 40 times longer, or 40·21
Therefore the real item is 840 inches long. Divide it by twelve to find how many feet long it is.
840/12=70
Therefore the real item is 70 feet long.
70ft
Hello there!
Explanation:
↓↓↓↓↓↓↓↓↓↓↓↓↓
I gave you a hint.
You had to used PEMDAS.
P-Parenthesis
E-Exponents
M-Multiply
D-Divide
A-Add
S-Subtract
First you had to calculate with parenthesis first.
Then you calculate with exponents.
You had to multiply and divide you had go to left to right.
Then you add or subtract you had go to left to right.

Answer:
y=2/3x-16/3
Step-by-step explanation:
Find perpendular by using negative reciprocal. Then plug in your x and y points into that equation, y=-2/3x-3 --> Then make y=2 and x=-1 --> 2=2/3(-1)+b
solve for b and ur done.
