Answer:
you spent all together 40.2+24.5+37.8=$102.50.
you saved 19.8+10.5+7.2=$37.50
![\frac{102.50}{140}](https://tex.z-dn.net/?f=%5Cfrac%7B102.50%7D%7B140%7D)
Step-by-step explanation:
To find the amount we spend, we multiply the original price by the decimal conversion of each fraction. Then we add the amounts together.
Sneakers cost $60 and you bought them at 2/3=0.6666....
60(0.67)=$40.20 and saved $19.80
Sweater costs $35 and you bought it at 7/10=0.7
35(0.7)=$24.50 and saved $10.50
A jacket costs $45 and you bought it at 5/6=0.8333...
45(0.84)=$37.80 and saved $7.20
We spent all together 40.2+24.5+37.8=$102.50.
We saved 19.8+10.5+7.2=$37.50
We could of spent paying regular price 60+35+45=$140. To find the fraction we place the total we actually paid over the total regular price.
Answer:
No. Se below for explanation
Step-by-step explanation:
If it is a right triangle it sides must meet the Pitgoras Theorem, wich says that the legs squared when summed must be equal to the square of the hypotenuse. Here the legs would be the sides of length 10 and 18, as the hypotenuse is always the longest. So we need to see:
10^ 2 + 18^2 = x
if x is equal to 21^2, so we can have a right triangle, if not, we cannot.
10^ 2 + 18^2 = 100 + 324
10^ 2 + 18^2 = 424
But:
21^2 = 441
So, as 10^2 + 18^2 < 21^2 this can not be a right triangle.
Answer:
Side length and perimeter of 1 face
Area of 1 face and surface area
Step-by-step explanation:
Suppose you are given cube with side length of x units.
Then
Side length = x units
Perimeter = 4x units
Area of 1 face
square units
Surface area
square units
Volume
cubic units
A linear relationship is any equation that, when graphed, gives you a straight line.
Consider all options:
A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function
is a straight line.
B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation
.
C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation
.
D. Area of 1 face and surface area is a linear relationship, because the graph of the function
is a straight line.
E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation
.
Answer:
19.42 ft
Step-by-step explanation:
c^2 = a^2 + b^2
c^2 = 16^2 + 11^2
c^2 = 256 + 121
c = √377 = 19.416
