Answers
Answer:
USQ = 227°
Step-by-step explanation:
∠ QPR = ∠ UPT = 47° ( vertical angles )
∠ QPR is equal to the measure of the arc that subtends it , so
arc QR = 47°, then
arc USQ = arc USR + arc QR = 180° + 47° = 227°
Answer:
227º
Step-by-step explanation:
USQ = 180+47 = 227º
What is the least number of cuts you would need to make to cut a 3 by 3 by 3 inch block of cheese into 1 by 1 by 1 inch blocks of cubes?
Answers
Answer:
6 Cut Minimum
Step-by-step explanation:
According to the Question,
You have a 3x3x3 cube.
First make two cuts parallel to base of the cube each at a distance of 1 unit . This leaves you with three cuboids of dimensions 3x3x1. Now make two parallel cuts parallel to the height of the cube. This leaves you with nine cuboids of dimensions 3x1x1. Now make the final two cuts each 1 unit apart parallel to width and you are left with 27 cubes of 1x1x1.So , the final answer is 6 cuts.

where
2/3 is the slope and -6 is the intercept
Step-by-step explanation:
4x-6y = 36
Simplify
2x - 3y = 18
put y on the LHS
-3y = 18 - 2x

Solve for X in the triangle. Round your answer to the nearest tenth
Answers
Answer:
x ≈ 10.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{14}[/tex] ( multiply both sides by 14 )
14 × cos42° = x , then
x ≈ 10.4 ( to the nearest tenth )

8. The Oklahoma Museum of Natural History claims that on average, a square foot of grass contains 3.1 x 10^3 blades of grass. The soccer field has an area of 1.148 x 10^5 square feet. How many blades of grass are on the entire soccer field?
Answers
Answer:
3.5588 x 10⁸
Step-by-step explanation:
(3.1 x 10³) (1.148 x 10⁵) = (3.1 x 1.148) (10³ x 10⁵)
= 3.5588 x 10⁸
9514 1404 393
Answer:
3.6×10^8
Step-by-step explanation:
Your calculator or spreadsheet can multiply these numbers for you and give you the answer in scientific notation.
(3.1×10^3)×(1.148×10^5) = (3.1×1.148)×10^(3+5) = 3.5588×10^8
The supplied numbers have 2 and 4 significant digits, so rounding of the answer to 2 significant digits is appropriate.
about 3.6×10^8 blades of grass are on the entire soccer field
