How is the ratio of crushed tomatoes to tomato paste different from the ratio of tomato paste to crushed tomatoes?

Answers

Answer and explanation:

The ratio 1:2 is different from the ratio 2:1. The ratio 1:2(one to two) means a comparison of two sizes; the ratio of one part of that thing to the ratio of two parts of that thing. Likewise, the ratio 2:1 is the comparison of two parts of a thing to the ratio of one part of the thing. For the ratio 2:1, we could say for example that for every two crushed tomatoes there is one tomato paste.

Answer: area mean multiply

Step-by-step explanation:

Answer:

76 feet (Just put 76 in the answer box)

Step-by-step explanation:

Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.

2(3.5) + 2(4.5)

The two products would be 7 and 9 respectively.

7 + 9 = 16 feet of fencing for 1 rabbit pen.

We have 2 pens, so multiply 16 by 2.

The rabbit pens need 32 feet of fencing.

(Alternatively you could have done 2(2(3.5 + 4.5)).

2(2(8))

2(16)

32 ft of fencing (rabbit pens))

Now, add 12 and 10. Then multiply that by 2.

2(12 + 10)

2(22)

The garden needs 44 feet of fencing.

Now add 32 and 44 to get the total amount of fencing needed.

32 + 44

The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)

9 ounces = how many pounds? in fraction form

Answers

Answer:

9/16 pounds

Step-by-step explanation:

1 pound = 16 ounces

With this information, we have make a proportion to find the number of pounds 9 ounces is

Let p = the number of pounds

16/1 = 9/p

Multiply both sides by 1 to get

16 = 9/p

Multiply both sides by p

16p = 9

Divide both sides by 16

p = 9/16

This fraction is in its simplest form and can't be simplified any more.

Quadrilateral IJKL is similar to quadrilateral MNOP. Find the measure of side NO. Round your answer to the nearest tenth.

Answers

Answer:

[tex]NO = 66.9[/tex]

Step-by-step explanation:

Given

See attachment for quadrilaterals IJKL and MNOP

Required

Determine the length of NO

From the attachment, we have:

[tex]KL = 9[/tex]

[tex]JK = 14[/tex]

[tex]OP = 43[/tex]

To do this, we make use of the following equivalent ratios:

[tex]JK : KL = NO : OP[/tex]

Substitute values for JK, KL and OP

[tex]14 : 9 = NO : 43[/tex]

Express as fractions

[tex]\frac{14}{9} = \frac{NO}{43}[/tex]

Multiply both sides by 43

[tex]43 * \frac{14}{9} = \frac{NO}{43}*43[/tex]

[tex]43 * \frac{14}{9} = NO[/tex]

[tex]\frac{43 * 14}{9} = NO[/tex]

[tex]\frac{602}{9} = NO[/tex]

[tex]66.8889 = NO[/tex]

[tex]66.9 = NO[/tex] --- approximated

[tex]NO = 66.9[/tex]

Answers

Answer:

Graph a

Step-by-step explanation:

Answer:

the answer is A

Step-by-step explanation:

to start, I would use the slope intercept, in this case -3 which lets you know the slope meets the y axis at (0,-3) since you have that point, you count with the slope.

now slope is rise over run, therefore, it would be y over x and since the y in this case is 3, you'd go up three from your point. since x is 4, you'd go right four units from where you are. since A is the only graph that follows that, A would be correct.

Christy spent 25 of her money on a shirt. She has $21.75 left. How much did she spend on the shirt?

A. $8.70
B. $7.25
C. $14.50
D. $29​

Answers

Christ spent a total amount of $ 14.50 on the shirt.

Finding the amount spent on the shirt

Here we use the linear equation concept to solve the problem.

Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.

Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below

Here we have

Christy spent 2/5 of her money on a shirt.

She has $21.75 left

Let 'x' be the amount that Christy has

From the data,

Christy spent 2/5 of her money on a shirt.  

Amount spent by Christy = 2/5 of x = 2x/5

Remaining amount = x - 2x/5

From the data,

Chrisy is left with $ 21.75

=> x - 2x/5 = 21.75

=> 3x/5 = 21.75

=> 3x = 108.75

=> x = 36.25

Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50

Therefore,

Christ spent a total amount of $ 14.50 on the shirt.

Caroline rolls a fair dice 480 times. How many times would Caroline expect to roll a six?

PLSSS ANSWER

Answers

a fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6

Since the dice is fair, each number (1 through 6) has an equal probability of appearing on each roll. The probability of rolling a six on any one roll is 1/6. Hence, 1/6 times of 480 is 80 times.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to occur.

To find the expected number of times Caroline would roll a six, we can use the formula:

Expected number of occurrences = Probability of occurrence x Number of trials

In this case, the probability of rolling a six is 1/6, and the number of trials is 480. Therefore, the expected number of times Caroline would roll a six is:

Expected number of times = (1/6) x 480 = 80

Therefore, Caroline would expect to roll a six 80 times out of 480 rolls.
