You work for a small business that sells bicycles, tricycles, and tandem bicycles (bicycles built for two). Bicycles have one seat, one front-steering handlebars, two pedals , and two wheels. Tricycles have one seat, one front-steering handlebars, two pedals, and three wheels. Tandem Bicycles have two seats, one front-steering handlebars, four pedals, and two wheels. Part A: On Monday, you counted forty-eight tricycle wheels. How many tricycles were in the shop? Write an algebraic equation that shows the relationship between the number of wheels (w) and the number of tricycles (t). Part B: On Wednesday, there were no tandem bicycles in the shop. There were only bicycles and tricycles. There were a total of twenty-four seats and sixty-one wheels in the shop. How many bicycles and how many tricycles were in the shop? Solve algebraically and show all your work. Let a = the number of tricycles Let b = the number of bicycles Part C: A month later, there were a different number of bicycles, tricycles, and tandem bicycles in the shop. There were a total of 144 front-steering handlebars, 378 pedals, and 320 wheels. How many bicycles, tricycles, and tandem bicycles were in the shop? Solve algebraically and show all your work. Let a = the number of tricycles Let b = the number of bicycles Let c = the number of tandem bicycles.

You went to the mall with $80 you spend 25% of your money on a pair of shorts and 65% of the remainder on sandels how much did you spend on the sandels.

Answers

80*0.25=20
20*65=13
You spend $13 on the sandals

well 80 is total
25% of 80 is 20
so total now is 60
65% of 60
10% is 6
60% is 36
5 % is 3
36 +3 is 39
you spend 39 on the sandels

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run? Round your answer to the nearest cm

Answers

Answer:

Chubby ran a distance of 6,283 m

Step-by-step explanation:

The length of one run is simply equal to the circumference of the circle

Mathematically, C = pi * d

C = 22/7 * 20 = 62.83 cm

So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;

62.83 * 100 = 6,283 m

Answer:

its 6280!

A 10 inch diameter pumpkin pie is cut into 6 equal servings. What is the area of the top of each piece of pie?

Answers

The area (A) of the whole circle is calculated through the formula, A = πd² / 4. Substituting the given diameter, A = π(10 in)² / 4 = 25π in². The area of the top of each piece is 1/6 of the this area. Thus, the answer is approximately 4.17 in².

What is the product 70 × 10 power of 4?

Answers

Answer: 700000

Explanation: 70 • 10= 700
700 to the power of 4= 700000

Pls give brainliest

Final answer:

The product of 70 and 10 to the power of 4, which can be solved using multiplication in scientific notation, is 7.0 × 105, or 700,000 in standard notation.

Explanation:

The question asks for the product of 70 times 10 to the power of 4. To solve this, we use the rule of multiplication in scientific notation wherein you multiply the numbers and then add the exponents. Hence, the equation is (7.0 × 101) × (1.0 × 104). In this equation, we multiply 7.0 and 1.0 to get 7.0, then add the exponents 1 and 4 to get 5. The answer is therefore 7.0 × 105, or 700,000 when written in standard notation.

what is the economic and political system in which the government controls property and the distribution of income? in this system, community ownership replaces private ownership. question 1 options: theocracy monarchy fudamentalism socialism

Answers

Let's look over the meaning of each option:

Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.

Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.

Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.

Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.

TL;DR: The answer is Socialism.
