Before school began, Mrs. Weeks bought a total of 86 balls. Total number of each type of ball 8. There are 18 Basketballs, 36 Baseballs, 15 Softballs

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Before school began, Mrs. Weeks bought a total of 86 balls.

Total number of each type of ball 8.

footballs - There are 8 footballs.

Basketballs - Two more than twice the number of footballs are Basketballs .

So, Basketballs = 2 + 2(8)

                          = 18

Baseballs - Four less than 5 times the number of footballs are

Baseballs .

So, Baseballs = 5(8)- 4

                       = 36

Softballs - Six more than half of the baseballs are softballs.

So, Softballs = 6 + 1/2 baseballs are softballs

                     = 6 + 1/2 (18)

                     = 15

Answer:

1) For 3 tickets, the cost is $12

2) For 5 tickets, the cost is $20

3) $28 can purchase 7 tickets

4) For 10 tickets, the cost is $40

Step-by-step explanation:

1) For 3 tickets

8 = 2

x = 3

(8 ÷ x) = (2 ÷ 3)

Cross multiply,

2x = 8 x 3

2x = 24

x = 24 ÷ 2

x = $12

Answer:

0.0238 meter per pieces

Step-by-step explanation:

(1/6)/7=0.0238

For confirmation:-

0.0238*7=0.1666=1/6

Answer:

0.02381m

Step-by-step explanation:

1/6 of a meter is 16.667 cm.

16.667 divided by 7 = 2.381cm

To check: 2.381 x 7 = 16.667 (correct)

2.381 cm in meters is 0.02381 m.

The answer is 0.02381m.

Answer:

2396

Step-by-step explanation:

Let the diameter = d

Let the height = h

Formula

Metric Tons = k * d^4 / h^2

Solution

Metric Tons = 64

d = 2

h = 9

k = ?

(You can't do the second part by not using a ratio unless you  put k in and solve for it)

64 = 2^4 k / 9^2

64 = 8 *k / 81

64 * 81 / 8 = k

5184 / 8 = k

k = 648

Solve for the second example

Metric Tons = d^4 * k / h^2

Metric Tons = ?

d = 5

h = 13

k = 648

Metric Tons = 5^4 * 648 / 13^2

Metric Tons = 625 * 648 / 169

Metric Tons = 2396 rounded.

Answer:

$301.50

Step-by-step explanation:

Given that:

Stuart brought a sweater on sale for 30% discount off.

Another 25% discount off

Original price = 600

To Find:
What was the final price of a sweater?

Solve:

$600 x 30% = $180

$600 - $180 = $402 (discounted price after 30% off)

$402 x 25% = $100.50

$402-100.50 = $301.50  (discounted price after 25% off & the final price)

Hence, the final price is $301.50

Step-by-step explanation:

The area of the quarter circle is equal to one-fourth area of the circle. Then the area of the quarter circle is 86.59 square inches.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

A corner shelf is 1/4 of a circle and has a radius of 10.5 inches.

Then the area of the quarter circle will be

[tex]\rm Area = \dfrac{\pi r^2}{4}\\\\\rm Area = \dfrac{\pi \times 10.5^2}{4}\\\\\rm Area = \dfrac{\pi \times 110.25}{4}\\\\\rm Area = \dfrac{346.36}{4}\\\\\rm Area = 86.59 \ \ in^2[/tex]

Answer: As a fraction it would be 333/ 1,332 and as a decimal it would be 0.25.

Step-by-step explanation:

1. you add all of the marbles and then you would get 1,332

2. there are 333 blue marbles, so it would be 333/1,332

3. if you want it in decimal form it will be 0.25 if you round that to the nearst tenth it would be 0.3.

Given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

Given the data in the question

Now, to get the height after 2 seconds, we substitute 2 for t in the equation.

h = -16t² + 15t + 12.

If t = 2

h = -16(2)² + 15(2) + 12

h = -16(4) + 30 + 12

h = -64 + 30 + 12

h = -64 + 42

h = -22ft

Therefore, given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

Step-by-step explanation:

Under Ryan's cell phone plan, he pays a flat cost of $68.50 per month and $5 per gigabyte. With a budget of $92.50, he can use up to 4 gigabytes of data.

Use the concept of subtraction defined as:

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that,

Ryan's flat cost per month is $68.50.

He pays $5 per gigabyte of data.

Ryan wants to keep his bill at $92.50 per month.

We know that Ryan pays a flat cost of $68.50 per month,

so subtract that from his budget:

$92.50 - $68.50 = $24.

Since Ryan pays $5 per gigabyte,

Divide the remaining budget ($24) by the cost per gigabyte ($5) to find out how many gigabytes he can use:

$24 / $5 = 4.8 gigabytes.

Therefore,

Ryan can use up to 4.8 gigabytes of data and still stay within his budget. Keep in mind that any fraction of a gigabyte will be rounded down,

So he can use a maximum of 4 gigabytes.

The correct answer is B. {0, 20, 40, 60, 80, 100, 120}

Step-by-step explanation:

1. Let's check all the information given to answer this question correctly:

Rate of each piano lesson Blake gives = US$ 20

Blake can give between 0 and 6 lessons every evening

Earnings = Number of lessons * Rate of each lesson

2. What is the range of this relation?

Let's recall that the domain of a relation is the set of all values for which the relation is defined, and the range of the relation is the set of all values that the relation takes.

It means that the domain of the relation in this case is the number of lessons that Blake can give every evening:

{0, 1, 2, 3, 4, 5, 6}

And the range of this relation is the amount Blake earns in an evening depending on the number of lessons he gives:

{0, 20, 40, 60, 80, 100, 120}

The correct answer is B. {0, 20, 40, 60, 80, 100, 120}

Answer:

x = -7

Step-by-step explanation:

8x - 2 = -9 +7x

in this type of problem you have to get all the X's together on one side, and all the common variables together on the other.

8x = -7 + 7x (you add 2 to boths sides. The -2 and 2 clear out on the left side. The 2 and -9 added together forms -7 on the right)

x = -7 (you subtract 7x from both sides. The 7x and -7x cancel out on the right and you are left with on 1 x on the left side)

Answer:

Step-by-step explanation:

In this question we have given an equation that is 8x - 2 = -9 + 7x . And we're aksed to find the value of x .

Solution : -

[tex] \longmapsto \qquad \: 8x - 2 = -9 + 7x[/tex]

Step 1 : Adding 2 to both sides :

[tex] \longmapsto \qquad \:8x - \cancel{ 2} + \cancel{ 2} = - 9 + 7x+2[/tex]

On further calculations, we get :

[tex] \longmapsto \qquad \:8x =7x - 7[/tex]

Step 2 : Subtracting 7x on both sides :

[tex] \longmapsto \qquad \:8x - 7x = \cancel{7x} - 7 - \cancel{7x}[/tex]

On further calculations, we get :

[tex] \longmapsto \qquad \: \red{\underline{\boxed{ \frak{x = - 7}}}}[/tex]
