Answer:

18 miles

Step-by-step explanation:

If Daniel ran 24 miles take away the 6 more miles he ran to get 19 miles.

Distance covered by Jasmine is 18 miles when Daniel had ran 6 miles

What is an expression?

Expression in mathematic is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

It is given that Daniel ran 6 miles more than Jasmine last week which means that if Daniel ran 24 miles than jasmine had ran 6 miles less then Danial that is 24 miles subtract 6 miles which comes out be 18 miles :

Distance covered by Jasmine = 24 miles - 6 miles = 18 miles in total

Therefore, Distance covered by Jasmine is 18 miles when Daniel had ran 6 miles.

Step-by-step:

The Town Recreation Department ordered 76 baseballs and 24 bats.

Given that, the total number of baseballs = 100, the total purchase = $822, cost of each baseball = $4.50 and the cost of each bat = $20.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let the number of baseballs be x and the number of bats be y.

Now, the total number of items = The number of baseballs + The number of bats

⇒ 100=x+y ------(I)

Total amount = 4.50x+20y

⇒ 4.50x+20y = 822 ------(II)

Solve the obtained equations:

Put x=100-y in the equation 4.50x+20y = 822

We get, 4.50(100-y)+20y = 822

⇒ 450-4.50y+20y=822

⇒ 15.5y=372

⇒ y=372/15.5

⇒ y= 24

So, x+y =100

⇒ x=100-24=76

Therefore, the Town Recreation Department ordered 76 baseballs and 24 bats.

Answer:

10 black- 10/20 - 50%

8 red- 8/20 - 40%

2 white - 2/20 -10%

Step-by-step explanation:

The total number of balls = 10 + 8 + 2 = 20 balls

probability of black balls = 10/20 = 50%

probability of red balls = 8/20 = 40%

probability of white balls = 2/20 = 10%

the three probabilities:

probability that the ball is one of the three colors = (10/20) + (8/20) + (2/20)

                                                                              = 1 = 100%

Explanation:

The complement of a subset is the subset of elements that are not in the given subset.

You must know which numbers the spinner has.

Assuming the spinner has the numbers 1, 2, 3, 4, the complement of spinning any number less than 3, is spinning a number that is not less than 3.

Then, that is spinning a number that is equal to or greater than 3.

The numbers that are equal to  or greater than four, for a spinner that has the numbers 1, 2, 3, and 4 are 3 and 4.

Thus, the complement of spinning any number less than 3 is spinning a three or a four.

The sum of the two given mixed numbers can be found several ways. One way is to write the fractions using a common denominator:

  1 3/4 + 1 5/8 = 1 6/8 + 1 5/8 = (1 +1) +(6/8 +5/8) = 2 + 11/8 = 3 3/8

David grew 3 3/8 in two years.

Both numbers are near and slightly more than 1.5, so their sum will be near and slightly more than 3.

The plastic pencil case has form of a triangular prism.

This triangular prism has five faces:

Surface area:

        area = (1/2) base × height

         area of one triangle = 10 cm × 12 cm × (1/2) = 60 cm²

          area of the two triangles = 2 × 60 cm² = 120 cm²

        area of a rectangle = length × width

         area of the trhee triangles = 24 cm × 10 cm + 2 × 24 cm × 13 cm = 240 cm² + 624 cm² = 864 cm².

Answer: first choice, 984 cm²

Answer: X=2.7

Step-by-step explanation:

-8x = 12x-54

subtract 12x from both sides

-20x= -54

divide both sides by -20

X=2.7

Answer:x=2/5

Step-by-step explanation:

25x2-8x=12x-4

25x2-8x-12x+4=0

25x2-20x+4=0

25x2-10x-10x+4=0

Answer:

Option B) triple the height

Step-by-step explanation:

The rest of the question is the container has a shape of the cylinder and the options to select the answer.

The options are:

A) triple the radius

B) triple the height

C) triple the diameter

D) triple the circumference

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

the container has a shape of the cylinder

The volume of the cylinder is = π r² h

It is required to choose which option is suitable so change the dimensions so that the volume is tripled.

So, the volume will be V' =  ( 3 π r² h )

Check the options:

A) triple the radius

The new radius = 3r

∴ V = π (3r)² h = 9 π r² h

B) triple the height

The new height = 3h

∴ V = π r² (3h) = 3 π r² h

So, it is no need to check the other options.

The answer is option B

Note: both of option C and D will lead to the same result of option A

Let's label the number you're trying to find x. You have to set up a system of equations.

1. Five times a number can be labeled as 5x.

2. Subtracted from 20 gives us 5x-20.

3. The problem says this is the same as simply tripling the original number. So set the first equation equal to 3x.

4. 5x-20=3x

5. Move like terms onto the same side. We can do this by subtracting 3x from both sides and adding 20 to both sides.

6. 5x-3x=20

7. 2x=20

8. Divide both sides by 2 to get x by itself.

Answer: x=10

The number is 2.5.

Let the number is = x.

According to the question:

20 - 5x = 3x

Add 5x.

20 = 5x + 3x

20 = 8x

Divide by 8.

x = 20/8 = 2.5

One cup of lemonade will cost $2.

Step-by-step explanation:

From simple observation and visual inspection we can conclude that one cup of lemonade costs $2.

If 9 cups of lemonade cost $18 then one cup of lemonade will cost $18÷9 = $2

If 2 cups of lemonade cost $4 then one cup of lemonade will cost $4÷2 = $2.

Therefore we can conclude that one cup of lemonade will cost $2.

Final answer:

Using the properties of similar triangles and the given side lengths, we solve for x and find that ED equals 8 units.

Explanation:

We're dealing with a geometry problem involving parallel lines and the properties of triangles. Since sides AB and CD are parallel, and triangles ABE and DCE share a common vertex at E, we can find the length ED using similar triangles and the given side lengths. The corresponding sides of similar triangles are proportional, so:

AB / AE = CD / ED
9 / (2x + 4) = 6 / (x + 4)

To solve for x, cross multiply and obtain the equation:

9(x + 4) = 6(2x + 4)
Then solve for x:
9x + 36 = 12x + 24
3x = 12
x = 4
Having x, we can find ED:
ED = x + 4 = 4 + 4 = 8 units

The valid sample for the survey would be students in Natasha’s social studies class and parents who live within a 2-mile radius of Natasha’s school.

The students in Natasha's social studies class are directly affected by the speed limit in front of her school, and the parents who live nearby are likely to have an opinion on the matter as well.

Two sevenths over two fifths = five over seven mile per hour

The unit rate is 5 over 7 miles per hour

Solution:

Given that, Suzanna walked two over seven of a mile in two over five of an hour

We have to find the unit rate in miles per hour

Unit rate means number of miles covered in 1 hour

From given information,

Two over seven of a mile in two over five of an hour

Which means,

[tex]\frac{2}{7} \text{ miles } = \frac{2}{5} \text{ hour }[/tex]

[tex]\text{ So she covered } \frac{2}{7} \text{ miles in } \frac{2}{5} \text{ hour }[/tex]

To find for number of miles covered in 1 hour, divide the [tex]\frac{2}{7} \text{ by } \frac{2}{5}[/tex]

[tex]\text{Unit rate in miles per hour } = \frac{\frac{2}{7}}{\frac{2}{5}}\\\\\text{Unit rate in miles per hour } = \frac{2}{7} \times \frac{5}{2} = \frac{5}{7}[/tex]

Two sevenths over two fifths = five over seven mile per hour

Answer:

small boxes = 5 and large boxes = 10

Step-by-step explanation:

Given:

The volume of each small box is 7 cubic feet.

volume of each large box is 13 cubic fee.

There were twice as many large boxes shipped as small boxes shipped.

Total volume of all boxes was 165 cubic feet.

Question asked:

The number of small boxes shipped and the number of large boxes shipped?

Solution:

Let  number of small boxes shipped = x

Then, the number of large boxes shipped = 2x (given)

Total volume of all boxes = 165 cubic feet.

no. of small boxes [tex]\times[/tex] vol. of each small box +  no. of large boxes [tex]\times[/tex] vol. of each large box =  165 cubic feet. (Total volume of all boxes)

[tex]x \times7 + 2x \times 13 = 165\\7x + 26x = 165\\33x = 165[/tex]

Dividing both side by 33

[tex]x = \frac{165}{33}\\ x = 5[/tex]

The number of small boxes shipped = [tex]x[/tex] = 5

The number of large boxes shipped = 2 [tex]x[/tex] = 2[tex]\times[/tex] 5 = 10
