Step-by-step explanation:

Answer: 4 flour + 3 sugar = 44lbs

6 flour = 48lbs

We can divide 48lbs by 6 bags of flour to get 8lbs per bag of flour.

4 bags of flour multiplied by 8lbs is 32lbs. 44lbs - 32lbs = 12lbs

12lbs divided by 3 bags of sugar = 4lbs per bag of sugar.

The ratio is flour to sugar: 8:4 or 2:1

We create two equations based on the information given: 4F+3S=44 and 6F=48. By solving these equations, we find the weight of a bag of flour is 8 pounds and the weight of a bag of sugar is 4 pounds. Thus, the ratio of weight is 2:1.

We can solve this problem by setting up two equations based on the information given and then solve the equations to find the weights of the bags of flour and sugar. Let's denote the weight of a bag of flour as F and the weight of a bag of sugar as S.

From the second equation, we can find that F = 48 / 6 = 8 pounds. Substitute F = 8 into the first equation, we find S = 4 pounds.

Therefore, the ratio of the weight of a bag of flour to a bag of sugar is 8:4 or simplified to 2:1 (option a).

Answer:

C. Cost of peanuts purchased

Step-by-step explanation:

The range is the values that the y variable, or the output can take.

The output is the cost of the peanuts

Answer: a) (x, y) → (x + 1, y + 3)

              b) (2, -5) → (3, -2)

Step-by-step explanation:

the x-axis goes left and right, so 1 step to the right means you need to add 1 unit to the x-coordinate.

the y-axis goes up and down, so 3 steps up means you need to add 3 units to the y-coordinate.

Rule:

If original x-coordinate is x, then the new coordinate is x + 1 (x → x+1)

If original y-coordinate is y, then the new coordinate is y + 3 (y → y+3)

Final position:

If original x-coordinate is 2, then the new coordinate is 2 + 1 (2 → 3)

If original y-coordinate is -5, then the new coordinate is -5 + 3 (-5 → -2)

Answer: 125.5 is the answer in decimal form. If you need it in fraction form it would be 251/2

To get this answer, you add up the parallel sides AB+DC = 69+182 =251

Then you divide by 2 leading us to get 251/2 = 125.5

The midsegment is basically the average of the two parallel sides

Answer:

circle E & circle F

Step-by-step explanation:

We want to see which circles are congruent to circle A, a circle of radius of 6 units.

The correct options are E and F.

Let's see how to solve this:

First, we need to understand what congruent figures are.

We say that two figures are congruent if they have the exact same shape and size.

Then we need to see which other circles also have a radius (distance from the center to the line) is also of 6 units. (or a diameter of 12 units)

The image of the options can be seen at the end of the answer, there, we can see that circle E has a radius of 6 units, so we know that circle E is congruent to circle A.

We also can see that circle F has a diameter (twice the radius) of 12 units, then the radius is:

R = D/2 = 12/2 = 6 units.

Then circle F is also congruent to circle A.

Then the correct options are E and F.

express the equation in slope-intercept form: f(x) = mx + b.

Here's a general outline of the process we'll follow once I have the graph:

Identify key features:

Slope: Determine the slope of the line, which signifies the rate of change of the function. You can calculate it using the formula slope = (change in y) / (change in x) between any two points on the line.

Y-intercept: Locate the point where the line intersects the y-axis. This point is crucial for determining the function's vertical shift.

Apply slope-intercept form:

Once you have the slope (m) and y-intercept (b), express the equation in slope-intercept form: f(x) = mx + b.

Verify with points:

Choose a few points on the graph and substitute their coordinates into the equation to ensure it accurately represents the line.

Total of 90 fish:

c + p = 90

Charlie gave 1/4 c to Peter.  Now

Charlie has c - (1/4) c

Peter has p + (1/4) c

Peter gave 2/5 of his to Charlie. Now

Peter has p + (1/4) c - 2/5( p + (1/4) c )

Charlie has c - (1/4) c + 2/5( p + (1/4) c )

And then they had equal number:

c - (1/4) c + 2/5( p + (1/4) c ) = p + (1/4) c - 2/5( p + (1/4) c )

Let's do the easy subtractions then multiply by 20 to clear the fractions,

(3/4) c + 2/5( p + (1/4) c ) = 3/5( p + (1/4) c )

15c + 8p + 2c = 12p + 3c

14c = 4p

7c = 2p

c + p = 90

2c + 2p = 180

2c + 7c = 180

9c = 180

c = 20

p = 70

Answer: Charlie started with 20, Peter with 70

Answer:

600

Step-by-step explanation:

Well, the closest number for 17 is 20, and for 27 is 30.

When we multiply those two numbers :

20*30=600

We got 600

To estimate 17 x 27 using compatible numbers, round 17 to 20 and 27 to 25, then multiply to get an estimated product of 500.

Using compatible numbers to estimate the product of 17 x 27 involves finding numbers close to 17 and 27 that are easier to multiply mentally, such as multiples of 10.

A good choice here would be to round 17 up to 20 and 27 down to 25 for the approximation.

By doing so, we simplify the multiplication to 20 x 25.

The estimated product using compatible numbers would be:

20 x 25 = 500

So, an estimated answer to 17 x 27 using compatible numbers would be 500.

This method provides a quick and easy way to estimate the result, which is particularly useful when exact calculations are not necessary, or you need a fast approximation.

Answer:

f(3) = - 1

Step-by-step explanation:

to evaluate f(3) substitute x = 3 into f(x)

f(3) = - [tex]\frac{2}{3}[/tex] × 3 + 1 = - 2 + 1 = - 1

Answer:

f3 = -1

Step-by-step explanation:

to evaluate f(3) substitute x = 3 into f(x)

f(3) = - \frac{2}{3} × 3 + 1 = - 2 + 1 = - 1

5x - 7y =58

y =-x +2

Using the substitution method, replace y in the first equation with the second equation:

5x - 7(-x+2) = 58

Simplify by using the distribution property:

5x - (-7x) - 14 = 58

Simplify by combining like terms:

12x -14 = 58

Add 14 from each side of the equation:

12x = 72

Divide both sides by 12:

X = 72/12

x = 6

Now you have x, replace x in the second equation and solve for y:

y = -x +2

y = -6 +2

y = -4

X = 6, y = -4

Answer:

x=15/a+b/a

Step-by-step explanation:

a*x=15+b

you need to move all the variables (a) to one side and to do that you can re-organize it to say

x*a=15+b

to get the answer you need to divide (a) and that gets you your answer,

x=15/a+b/a

Here is your equation:

[tex]ax=15+b[/tex]

You're trying to find x alone. To find a specific variable, you have to do the opposite of what's happening to the variable, which is x in this equation.

In this equation, x is being multiplied by a. That means you have to do the opposite of multiplying, which is dividing by a. To leave x alone, divide both sides by a.

[tex]ax \div a = \frac{15+b}{a}[/tex]

Now that you have divided both sides by a, which leaves x alone, you have:

[tex]x = \frac{15+b}{a}[/tex]

Your answer is [tex]x = \frac{15+b}{a}[/tex]

Answer: AFC won 18 times, NFC won 20 times

============================

N = number of times an NFC team won the superbowl

A = number of times an AFC team won the superbowl

The two unknown numbers (N and A) must add to 38 as there are no other options (either there is an NFC or AFC champion) so N+A = 38

The other equation is N = A+2 because "the NCF won two more games than the AFC"

We can replace the "N" in N+A = 38 with A+2 because N = A+2, meaning that N and A+2 are the same

So,

N+A = 38

A+2+A = 38  ... replace N with A+2; solve for A

2A+2 = 38

2A+2-2 = 38-2

2A = 36

2A/2 = 36/2

A = 18

The AFC won 18 times. Use this value of A to find N

N = A+2

N = 18+2

N = 20

The NFC won 20 times.

As a check, adding up the two counts should get us 38

N+A = 38

20+18 = 38

38 = 38

Answer: 10%, 0.5, 3/4

Step-by-step explanation:

What you want to do is convert them all to one unit. The eaisest would be a decimal.

Starting off with .5, it's already in decimal form.

Next go to 10%. 10% as a decimal will be 0.1, because its 1/10.

Lastly, go to 3/4. 3/5 as a decimal would be 0.75.

Putting them in order from least to greatest would be 10%, 0.5, 3/4.

(Hope that helps)

Answer:

10%, 0.5, 3/4

Step-by-step explanation:

This is actually quite simple, all you need is a quick calculation.

I'm going to convert all of the numbers to decimals for the easiest comparison.

put 3/4 into a calculator, and you get 0.75

0.5 is already a decimal

and with percents, you just move the decimal point back two, making it 0.1

Now you have an easy way to compare: 0.1 is the least, 0.5 is next, the 0.75 is the largest.

Hope this helps =D

Answer:

2 and 1/4 or 2.25. Both numbers are the same.

Step-by-step explanation:

Hi,

Please see the picture I had to upload in order for this question to be complete. Please also note that Kara has 3 buttons in the 3/4 length. You have to sum up only those in that length and ignore the ones in different lengths.

It is a very simple multiplication, and there are 2 ways to do so. You can use either fractions or integer numbers. See the 2 options below:

3/4 (fractions) = .75 (integer numbers)

Option one - 3 * 3/4 = 9/4 which is represented by 2 and 1/4.

Option two - 3 * .75 = 2.25

To determine the remaining fraction of juice in the bottle, subtract the poured amount from the original 20 ounces. The fraction left in the bottle is 3/5 of the original 20 ounces.

To find the fraction of juice left in the bottle:

Start with 20 ounces.

Pour out 1/4 for a friend, which is 5 ounces (1/4 of 20).

Pour out 3 more ounces for yourself.

Subtract the total poured out (5 + 3 = 8) from the starting amount (20) to find what's left.

So, 20 - 8 = 12 ounces left in the bottle, which represents 3/5 of the original 20 ounces.
