Answer: 96 cm^3
To answer this, start by finding the volume of the square prism. The formula is L x W x H, therefore the volume is 3 x 3 x 10 = 90.
Then, find the volume of the pyramid on the top. Use the same formula but divide it by 3 because it is a pyramid. 3 x 3 x 2 / 3 = 6
Add 90 and 6 to get 96.
Answer:
A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)
Step-by-step explanation:
The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).
The mapping for a rotation through 90° clockwise about the origin is
Therefore:
Therefore the image rectangle has coordinates:
A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)
The first choice is correct.
3•2•7=42•2=84
12•10•7=840
84+840=924in^3
Answer:
1 wall is 0.75 gallons. 3 walls is 2.25 gallons.
Step-by-step explanation:
if 1 gallon covers 1 1/3 wall, divide 1/1.3333 = 0.75
multiply 0.75(1 wall) by 3.... 0.75×3=2.25
The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA
SOH = Sin is OPPOSITE / HYPOTENUSE
CAH = Cos is ADJACENT / HYPOTENUSE
TOA = Tan is OPPOSITE / ADJACENT
For example if we were to solve question 5
Sin T = 6 root 2 / 19
Cos T = 17 / 19
Tan T = 6 root 2 / 17
Repeat the steps for question 6
For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1
for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so
cos x = 9 / 18
to find x plug: cos^-1 (9/18) in the calculator
