Answer:

n(B U S) = 75

Step-by-step explanation:

P(E) =  

Let 'B' be the event of having twelve year old brother

Let 'S' be the event of having twelve year old sister

given data  P(BUS) = 0.25

given total survey  n(survey) = 300

we have to find the value is n(BUS) =?

we will use probability definition we get, P( BUS) =

substitute given values, we will get solution

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75

Answer:

75 twelve-year-olds will have a brother or sister

25% of 300 = 75

Step-by-step explanation:

Step 1: Our output value is 300.

Step 2: We represent the unknown value with x

Step 3: From step 1 above, 300=100%.

Step 4: Similarly, x=25%

Step 5: This results in a pair of simple equations:

300=100% (1).

x=25% (2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

300/x    100%/25%

Step 7: Again, the reciprocal of both sides gives

x/300     25/100

x=75

Therefore, $25% of 300 is 75

Answer:

y = 9.

Step-by-step explanation:

y = kx where k is a constant.

Substituting the given values:

15 = k*10

k = 15/10 = 1.5 so

y = 1.5x is the relation.

When x = 6

y = 1.5 * 6

= 9..

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y = kx

k = 1.5 and x = 6

The value of y when x = 6 is 9.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

3x = 5 is an equation.

We have,

If y varies directly as x.

This means,

y ∝ x

y = kx

where k is the constant of proportionality.

Now,

y = 15 when x = 10

This means,

15 = 10k

k = 15/10

k = 1.5

Now,

y = kx

k = 1.5

x = 6

y = 1.5 x 6

y = 9

Thus,

y = kx

k = 1.5 and x = 6

The value of y when x = 6 is 9.

A customer purchased 1/4 pound of ham, 1 1/2 pounds of turkey, 1 pound of roast beef, and 3/4 pound of bologna. Therefore, the customer pay for the purchase before sales tax is $22.

Sales tax:

A sales tax is a tax paid to a governing body on the sale of certain goods and services. Laws generally allow sellers to collect taxes from consumers at the time of purchase. When a tax on goods or services is paid by consumers directly to the governing body, it is usually called a use tax. Laws often provide excise and use tax exemptions for certain goods or services, such as: food, education, medicine, etc. Value Added Tax (VAT) charged on goods and services is related to sales tax.

For Example:

I am shopping at The Clothing Boutique and would like to estimate the total after tax before checking out. After counting the total price of the items in the cart, the total is $100. Sales tax in this county is 9.5%, so you charge 9.5% (100 x 0.095) of $100.

According to the question:

The purchase before sales tax:

                   = 1/4 × $5.99 + 1 1/2 × $4.99 + 1 × $6.99 + 3/4 ×2.99

                   = $1.5 + $7.5 + $6.99 + $5.24

                   = $21.23 ≈ $22

Therefore,  the customer pay for the purchase before sales tax is $22.

Using multiplication as a mathematical operator, Kareem will 864 more cards and Nicole will get 24 more cards

Multiplication is a mathematical operation that involves multiplying two or more numbers together. It is one of the four basic operations in mathematics, along with addition, subtraction, and division.

In this problem, we may require the use of some mathematical operators to find the solution to the problem.

1.

He currently has 216 cards, but he needs 15 sets of cards.

1 set of card = 72 cards

Let's calculate the number of sets he currently has.

1 set of card = 72 cards

x set = 216 cards

cross multiply both sides and solve for x.

x * 72 = 216 * 1

x = 216 / 72

x = 3 sets

He currently has 3 sets of cards.

Since he wants 15 sets of cards, we will need 12 more set of cards.

The number of cards can be calculated by multiplying 12 by 72

Number of cards = 12 * 72 = 864

He needs 864 more cards.

2.

1 set of card = $27

1 set = 72 cards

But she's bringing $9 to join, we can calculate the ratio of cards she will get.

1 / 27 = x / 9

x = 9 / 27

x = 1/3

She will get 1/3 of the cards bought which will be

72 * 1/3 = 24 cards

She will get 24 cards

Answer:

$64.00

Step-by-step explanation:

Let the amount for the groceries before tax be Y

If the cost inclusive of tax at 7% is $68.48, then

Y + 7% * Y = $68.48

100%Y + 7%Y = $68.48

107%Y = $68.48

Recall that 107% = 1.07

1.07Y = $68.48,

Divide both sides by 1.07

Y = $68.48/1.07

Y = $64.00

Hence the cost of the groceries before tax is $64

Answer: the answer is 1800

Step-by-step explanation:

18 percent of 10000 is 1800

All must add up to 360°

100+44=144°

360-144

= 216°

Answer:

144°

Step-by-step explanation:

Every possible triangle's 3 angles add up to 180.

So when you are given 2 angles of a triangle (100° and 44°), you can find the 3rd one by subtracting the given angles from 180°.

100°+44°=144°

180°-144°=36°

That's the missing angle inside the triangle.

We need that to find angle 1 because 2 angles that make up a straight line add up to 180°. So 180-36°=144°.

Answer:

The answer is $4.50.

Step-by-step explanation:

To solve this problem, divide the result ($6.75) by the percentage (150%). This gives you the original number which was multiplied by the percentage. So,

$6.75 / 150% = $4.50.

Answer:

$4.50

Step-by-step explanation:

150% × □ = $6.75

First, we can rewrite 150% as the fraction 3/2.

[tex]\dfrac{3}{2} \times \square = \$ 6.75[/tex]

Then, we can also rewrite 6.75 as the fraction 27/4.

[tex]\dfrac{3}{2} \times \square = \$ \, \dfrac{27}{4}[/tex]

Next, we can isolate the unknown by multiplying both sides by 2/3 (the reciprocal of 3/2).

[tex]\left(\dfrac{2}{3} \right)\left(\dfrac{3}{2} \times \square \right) = \left(\$ \, \dfrac{27}{4}\right)\left(\dfrac{2}{3} \right)[/tex]

After that, simplify by multiplying out the numerators and denominators on the right side of the equation.

[tex]\square = \$ \, \dfrac{27 \times 2}{4 \times 3}[/tex]

[tex]\square = \$ \, \dfrac{54}{12}[/tex]

Finally, simplify the expression on the right side to a decimal form.

[tex]\square = \$ \, \dfrac{54 \div 2}{12 \div 2}[/tex]

[tex]\square = \$ \, \dfrac{27 \div 3}{6 \div 3}[/tex]

[tex]\square = \$ \, \dfrac{9}{2}[/tex]

[tex]\square = \$ 4.50[/tex]

For this problem, the sailors and the lifeboat are traveling in opposite directions, hence the relative velocity, considering each of their velocities is given as follows:

v = 14 + 3 = 17 miles.

(meaning that they get 17 miles farther each hour).

Velocity is distance divided by time, hence the time it will take for them to be 57 miles apart is given as follows:
