Question: the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with.

If the chess club accepts 5 each week and they had 6 members after 6 weeks you should multiply 5x6=30. We don't know when the chess club started.. it could be 6 or 7 weeks ago and I'm pretty sure we all know that 7x5=35. but it only says 6 weeks ago so the answer is 7,

Solve using a proportion and an equation. Kendra found the experimental probability of her making a penalty kick in soccer is 3/10 or 30%. Out of 40 penalty kicks, how many could she predict she will make?

Answers

Answer: The predicted number of penalty kicks = 12

Step-by-step explanation:

Given : The experimental probability of her making a penalty kick in soccer is 3/10 or 30%.

So, the proportion of penalty kicks she make = 0.3

Out of 40 penalty kicks, the predicted number of penalty kicks = 0.3 x 40

= 12

Hence, the predicted number of penalty kicks = 12

A baker made 9 cupcakes, each a different type. Four people want to share them equally. How many cupcakes will each person get? DIvide and use in fraction form.

Answers

Answer: 2 1/4

Step-by-step explanation:

From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.

To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:

= 9 ÷ 4

= 2 1/4 cupcakes

Therefore, each person gets 2 1/4 cupcakes.

(2 points)3.034.285.396.43 Which detail best supports the inference that James Watt could not have made the improvement to his steam engine without the assistance of Matthew Boulton? The Steam Engine James Watt, who secured the position as a maker of scientific instruments in the University of Glasgow, proposed an idea for improving the existing steam engine, which was used for pumping mines. For a long time, owing to a lack of money, he had difficulty in establishing the merits of his improvements. Finally, he formed a partnership with Matthew Boulton, a wealthy and energetic man who lived at Birmingham, England. They began the manufacture of steam engines at Birmingham, under the firm name of Boulton and Watt. This partnership was very successful. Watt supplied the inventions; Boulton furnished the money and attended to the business. Before the time of Watt, the steam engine was exclusively a steam pumpslow and wasteful of fuel. Watt made it a quick, powerful, and efficient engine, requiring only a fourth as much fuel as before. Under his first patent, the engine was still used only as a steam pump, but his later improvements adapted it for driving stationary machinery of all kinds. The commercial success of his engine was soon fully established. X +2 = 8 What is X in this problem/situation ?????????????HELP ME!!!!!!!!!!!!!
