  41 2/3 feet

Step-by-step explanation:

The sum of wall lengths (in feet) is ...

  (12 1/4) + (10) + (12 1/4) + (10 -2 5/6)

  = (12 + 10 + 12 + 8) + (1/4 + 1/4 - 5/6)

Jeremy has 144 marbles. He gives half to Marsha. Then he gives half of what he has left to Sam. He shares in the same way with two more friends. Write the terms that shows the number of marbles Jeremy has.

Answers

Hey!

So, If you want to figure out how much marbles Marsha gets, you first divide 144 by 2. And that equals 72. So Marsha gets 72. THEN, Halve goes to Sam so Sam gets halve of 72. And halve of 72 is 36. 

SO MARSHA GETS 72 MARBLES JEREMY GETS 36 AND SAM GETS
36.


Yeah Marsha gets 72 marbles and Jeremy gets 36 and Sam gets 36

Write each ratio as a fraction in simplest form. Then explain its meaning. 4 flutes and two drums

Answers

The ratio would be 4:2. In simplest form, it would be 2:1. The meaning is that since there are 4 flutes, the first ratio number would be 4. Same with the 2 drums. How you would simplify it is that you have to minus it down. Since 2 can go into 4, the logical answer would have to be 2:1

The ratio as a fraction in its simplest form for the Number of drums and flutes is 1:2.

What is a Ratio?

A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.

A ratio shows us the number of times a number contains another number. Given the following details:

Number of drums = 2

Number of flutes = 4

The ratio for the number of drums to the number of flutes in its simplest form can be written as,

Number of drums / Number of flutes = 2 / 4

Dividing both the numerator and the denominator of the fraction by 2, we will get,

Number of drums / Number of flutes = 1/2

Hence, the ratio as a fraction in its simplest form for the Number of drums and flutes is 1:2.

For each handmade card Jacquie sells, she makes a profit of $0.35. In one week she made a profit of $42. she sells the cards for $0.75 Part 1 : about how many greeting cards do she sell that week? Part 2 : about how much did she earn before paying expenses?

Answers

Answer:

A) 120 cards; and

B) $90.

Explanation: Let x be the number of greeting cards sold that week. She earns $0.35 per card and earned $42; this gives us the equation 0.35x = 42 Divide both sides by 0.35: 0.35x/0.35 = 42/0.35 x = 120 She sold 120 cards. She sells each card for $0.75. This means she earned 0.75(120) = $90.

a recipe calls for 1 1/2 cups of flour, 3/4 cups of white sugar, and 1/3 cup of brown sugar the recipe makes 6 servings.

(a) how many total cups of flour are there per serving? show your work

(b) how many total cups of sugar (white and brown) are there per serving?show your work

(c) supposed you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe?Show your work

Answers

Answer:

(a) 0.25 cups of flour

(b) 0.18 cups of sugar

(c) 0.5 cups of flour

Step-by-step explanation:

The recipe requires 3 amounts of ingredients to make 6 servings. The following is needed:

1. 1 1/2 cups of flour

2. 3/4 cups of white sugar

3. 1/3 cups of brown suger

a) The total cups of flour per serving can be determined by dividing the flour needed for 6 servings by 6:

[tex]=1.5/6=0.25[/tex]

0.25 cups of flour is needed per serving

b) The total cups of brown and white sugar can be determined by divided both quantites by 6 servings.

For brown sugar = 0.75/6 = 0.125 cups of brown sugar

For white sugar = 0.333/6= 0.0555≈0.055 cups of white sugar

Total amount of sugar = brown sugar + white sugar = 0.125+0.055=0.18 cups of sugar

c) If we can make 9 servings we can determine the the percentage of more servings and the amount of flour for the modified recipe.

The percentage change of recipes = ((9-6)/9)*100=33.33%

Therefore the new amount of flour needed is:

[tex]1.5*0.3333+1.5=2[/tex]

Therefore we need 2-1.5=0.5 cups more flour than the original recipe

when five is added to three more than a certain number,the result is 19.what is the number?

Answers

when 5 is added to 3 more then a certain number, the result is 19

x + 3 + 5 = 19
x + 8 = 19
x = 19 - 8
x = 11 <== ur number

Five is added to three more than a certain number, resulting in 19

5 + 3 + (x) = 19

8 + x = 19

x = 19 - 8 = 11


Thus, the certain number is 11.
