Tell whether the angles are complementary or supplementary. Then find the value of x.
Answers
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.
Convert 67,000 pounds to tons. Choose the words and numbers to complete the statements.
A pound is larger/smaller than a ton, so multiply/divide the number of pounds by 16/1,000/2,000 to find the number of tons. Therefore, 67,000 pounds is 33.5/67/4,187.5/134,000,000 tons.
Answers
The words and numbers to complete the statements is: A pound is smaller than a ton, divide the number of pounds by 2,000 to find the number of tons.
A pound is smaller than a ton which means that a ton is larger that pound. Therefore we would need to divide the number of pounds which is 67,000 by 2,000 to deterine the number of tons.
Hence:
Number of tons= 67,000 pounds/2000
Number of tons=33.5 tons
Inconclusion a pound is smaller than a ton, divide the number of pounds by 2,000 to find the number of tons.

Which space mission from Earth traveled to the moon at a faster pace, Apollo 11 or Luna I?
Apollo 11 - 8.35 * 10^1 kilometers/minute
Luna l - 1.76 * 10^2 kilometers/minute
Answers
Answer:
Apollo 11 - 8.35 * 10^1 kilometers/minute
Step-by-step explanation:
The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth.
Additional flight objectives included scientific exploration by the lunar module, or LM, crew; deployment of a television camera to transmit signals to Earth; and deployment of a solar wind composition experiment, seismic experiment package and a Laser Ranging Retroreflector. During the exploration, the two astronauts were to gather samples of lunar-surface materials for return to Earth. They also were to extensively photograph the lunar terrain, the deployed scientific equipment, the LM spacecraft, and each other, both with still and motion picture cameras. This was to be the last Apollo mission to fly a "free-return" trajectory, which would enable a return to Earth with no engine firing, providing a ready abort of the mission at any time prior to lunar orbit insertion.
Answer:
The average speed of Luna I was 1.76 x 10^2 kilometers/minutes. The average speed of Apollo 11 was 8.35 x 10^1.
The average speed of Luna I was greater than the average speed of Apollo 11. So, Luna I traveled at a faster pace than Apollo 11.

Sophia has $6 to spend on lunch during a basketball tournament. The concession stands sell sodas for $0.75 and all of their food items for $1.50. What is the maximum number of food items Sophia can purchase if she buys one drink?
Answers
Important info:
- Sophia has $6 to spend on lunch
- Concession stands sell sodas for $0.75
- All of their food items for $1.50
- Pretend she buys one drink
- Find the maximum amount of food she can buy now.
Process:
Subtract 600 and 75 since $6 = 600 cents
600 - 75 = 525
So Sophia has $5 and 25 cents left
Each food item is worth $1.50 which is 150 cents and she currently has $5.25 which is 525 cents
So divided 525 and 150
525 / 150 = 3.5
Unfortunately she can't buy half of a food item so the answer would be 3
Final Answer:
3, Sophia can buy 3 food items after buying 1 drink
