Answer:
x= - 1364/7
Step-by-step explanation:
22/ 21
x=−186
21x = -186 x 22
=4092/21 =-1364/21
Answer:
64
Step-by-step explanation:
4^3, means 4*4*4, and it is very simple to calculate when you break it down to 4*4= 16 and then 16*4=64. So your final answer is 64.
Answer: C) Three-fourths
I.e., the fraction 3/4
======================================================
Explanation:
Let's pick on the horizontal sides. Divide the image length Y'Z' = 9 over the corresponding preimage length YZ = 12 to get
(Y'Z')/(YZ) = 9/12 = 3/4 which is the scale factor
The scale factor is less than 1, meaning the image's lengths are shorter compared to the preimage's corresponding lengths.
-----------------
Alternative Paths:
You can pick any other pair of corresponding sides to get the same result:
- (X'Y')/(XY) = (7.5)/(10) = 75/100 = 3/4
- (Z'X')/(ZX) = 6/8 = 3/4
Answer:
y = 1/2x -1
Step-by-step explanation:
to find the y-intercept you find where the line crosses the y axis
for the slope you need to use the equation
change of y2 - change of y1
change of x2 - change of x1
In this question, you are given the water volume(6.2 cubic ft) and the water density (8.33 pounds/gallon). To find the water mass you need to multiply the volume with density, but you need to convert it so they have same unit.
The calculation would be:
mass = volume x density
mass = 6.2 cubic ft x 7.48 gallon/cubic ft x 8.33 pound/gallon= 386.31208 pounds.
In ounce it will be= 386.31208 pounds x 16 ounce/pouns= 6180,99328 ounces
