Answer:

You should buy from the first store

Step-by-step explanation:

Since there are 4 quarts in a gallon, we will need to multiply .80 by 8 to figure out how much it costs for 2 gallons. This will be $6.40 for the second store, and in order to find out how many the first store offers, we multiply 3 by two, which is six.

So, the first store charges $6.00 for two gallons, and the second store does $6.40 for two gallons of milk

Answer:

The first store.

Step-by-step explanation:

This is easy, multiply 0.80 x 4 since there are four quarts in a gallon. You get 3.20. Then, multiply 3.20 by 2 to get 6.40 and 3.00 by 2 to get 6.00.

So

Store number one: $6.00

Store number two: $6.40

the shadow of the woman will be 7.5 feet.

the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.

Given, A 5-foot woman stands near a 4-foot cello case. The cello case casts a shadow that is 6 ft long.

Since the shadows are made because of the light of the Sun. thus we will assume the Angle of Light source will be the same.

So In angles are the same then

Base and perpendicular will be in proportion as per the Pythagorean theorem

So,

Women's height/cello's height = Women's shadow/cello's shadow

=> 5/4 = women's shadow/ 6

=> women's shadow = 7.5 ft

Therefore, the shadow of the woman will be 7.5 feet.

Final answer:

Joyce has read 9/10 of her book over the course of three days by adding together the fractions of the book she read each day and simplifying the result.

Explanation:

To determine the part of the book Joyce has read over the three days, we need to add the fractions representing the parts read each day. On Monday, Joyce reads 1/6 of her book, on Tuesday she reads 2/5, and on Wednesday she reads 1/3. Thus, we add these fractions together.

The Least Common Denominator (LCD) for 6, 5, and 3 is 30. We convert each fraction to have this common denominator:

Now, we sum the fractions:

5/30 + 12/30 + 10/30 = (5 + 12 + 10)/30 = 27/30

27/30 can be simplified to 9/10 after dividing both numerator and denominator by 3. So, Joyce has read 9/10 of her book over the three days.

Answer:

He should have 3 pencils in each package.

Step-by-step explanation:

you would do 7272 divided by  2424 so that there is a pencil for each calculater.

Answer:

The number of pencils in each package is 3.

Step-by-step explanation:

The total number of pencils = 7272

The number of calculators = 2424

He has to create greatest number of package and the condition is he has to use all the calculator and pencils.

The minimum number is 2424 which is number of calculators, So he can create maximum of 2424 packages. He must use all 7272 pencils.

So to find the number of pencils, we need to divide the number of pencils by the number of calculators.

The number of pencils in each package = [tex]\frac{7272}{2424}[/tex] = 3

The number of pencils in each package is 3.

Answer:

r < -7 or r > 10

Step-by-step explanation:

-2|3 - 2r| < -34

|3 - 2r| > 17      (Note the inequality sign flips because we divide by negative)

Now we split it up into 2 inequalities :-

3 - 2r > 17

-2r > 14

r  < -7     (answer)

and

3 - 2r < -17

-2r < -20

r > 10  (answer).

Answer:

r > 10 or r < - 7

Step-by-step explanation:

isolate the absolute value by dividing both sides by - 2

| 3 - 2r | > 17

Inequalities of the type | x | > a always have solutions of the form

x < -a OR x > a, hence

3-2r < - 17 or 3 - 2r > 17 ( subtract 3 from each interval )

- 2r < - 20 or  - 2r > 14 ( divide both intervals by - 2 )

Remembering to reverse each inequality symbol as a result of dividing by a negative quantity.

r > 10 or r < - 7

Answer:

13.1

Step-by-step explanation:

Note the place values

1 : tens

3 : ones

.  (decimal point)

0 : tenths

9 : hundredths.

Solve for the tenths place value. Note the hundredth value, it is a 9

Because 9 is greater than 5, round up.

13.09 rounded to the nearest tenth is 13.1

~

To round 13.09 to the nearest tenth, we increase the tenths place by 1 since the hundredths place is 9. Thus, the number rounds up to 13.1.

The question asks to round the number 13.09 to the nearest tenth. To do this, we look at the hundredths place, which is 9 in this case. Since the digit in the hundredths place is 5 or more, we round the digit in the tenths place up. Therefore, 13.09 rounded to the nearest tenth is 13.1.

Step-by-step explanation:

We can see that the given glass is in form of a cone.

To find the height of liquid in glass we will use formula:

[tex]h=\sqrt{l^2-r^2}[/tex], where,

h= Height of cone.

l= Slant height of cone.

r= Radius of cone.

We can see from our figure that diameter of cone is 6 cm, so radius of cone will be half of 6 cm, that is 3 cm.

We have been given slant height equals to 7 cm.

Let us substitute our values in above formula to find the height of liquid in the glass.

[tex]\text{Height of liquid in the glass}=\sqrt{7^2-3^2}[/tex]

[tex]\text{Height of liquid in the glass}=\sqrt{49-9}[/tex]

[tex]\text{Height of liquid in the glass}=\sqrt{40}[/tex]

[tex]\text{Height of liquid in the glass}=6.3245553203367587\approx 6.32[/tex]

Therefore, the height of liquid in the glass is 6.32 cm.

d. x=11, y=-5,  z= -71

To solve the given system of equations, we use the method of substitution. The solution is x = 11, y = -5, z = -71.

To find the solution of the given system, we can use the method of substitution.

From the first equation, we have x = -3y - 4. Substituting this value for x in the second equation, we get -3y = 2(-3y - 4) - 7.

Solving this equation, we find y = -5. Substituting this value of y back into the first equation, we can solve for x. Plugging in y = -5, we get x = 11. Substituting these values for x and y in the third equation, we can find z. Plugging in x = 11 and y = -5, we get z = -71.

Therefore, the solution to the system is x = 11, y = -5, and z = -71.

Answer:

The number of hamburgers sold was 126.

Step-by-step explanation:

Let h = number of hamburgers sold

let c = cheeseburgers sold

c+h = 378

c = 2h

Substitute c =2h into c+h =278

c+h =378

2h+h = 378

Combine like terms

3h = 378

Divide by 3

3h/3 =378/3

h =126

The number of hamburgers sold was 126.

Final answer:

To determine how many hamburgers were sold, we set up a system of equations and found that 126 hamburgers were sold.

Explanation:

The local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers. We are told that the number of cheeseburgers sold was 2 times the number of hamburgers. We can set up a system of equations to solve this problem using h to represent the number of hamburgers and c to represent the number of cheeseburgers:

h + c = 378 (the total number of burgers sold)

c = 2h (the number of cheeseburgers was 2 times the number of hamburgers)

Now let's substitute the second equation into the first to solve for h:

h + 2h = 378

3h = 378

h = 378 ÷ 3

h = 126

Therefore, the number of hamburgers sold was 126.

Answer:

they each used 1.5 quarts    PLEASE GIVE BRAINLIEST

Step-by-step explanation:

10.5 ÷ 7 = 1.5 QUARTS FOR EACH GROUP

To find out the amount of water each group used, the total quantity of water, 10 1/2 quarts, should be divided by the number of groups, which is 7. This gives the result of each group using around 1.5 quarts.

To find out how many quarts each group used in the experiment, you would need to divide the total amount of water by the number of groups. In this case, you would divide 10 1/2 quarts by 7 groups.

First, you need to convert the mixed number 10 1/2 to an improper fraction or a decimal. 10 1/2 equals 21/2 or 10.5 in decimal form.

So, 10.5 quarts divided by 7 groups equals approximately 1.5 quarts.

Therefore, each group used 1.5 quarts of water for their experiment.

Answer: This is a function

There are no repeated x values. Each x value is paired with exactly one y value. If you had an input of something like x = 3 lead to y = 5 and y = 8 at the same time, then it wouldn't be a function.

If you want, you can graph all five of these points, as is shown in the attached image below. You'll notice that it is impossible to draw a vertical line through more than one of these five points. The graph therefore passes the vertical line test to visually confirm we have a function.
