Answer:

Oliver had 56 marbles and he divided them equally in 8 groups. The number of marbles in each group = 56 marbles ÷ 8 groups = 7 marbles per group.

Step-by-step explanation:

In order to determine the number of marbles in each group you just have to divide the total number of units by the number of groups. In this case, the result is a whole number.

Answer:

60 km/h

Step-by-step explanation:

Average speed is total distance over total time.

Total distance: 30 + 0 + 150 = 180 km.

Total time: 0.75 + 0.25 + 2 = 3 hrs.

180/3 = 60/1

the answer should be 38

Answer:

The answer is 54

Step-by-step explanation:

Let us evaluate the exponent first

(3/4)^3 = 27/64

so we have

27/64 divided by 1/128

= 27/64 * 128/1 = 27 * 128/64

= 27 * 2 = 54

Answer:

y = -2/5x + 9

Step-by-step explanation:

The slope will always be before the x. And intercept will always go after the slope. If your intercept is negative, remember to write it as x-9 rather than x+9.

And you'll always want to add the y = at the beginning

Step-by-step explanation:

To figure this out, we need to add both amounts of grapes together. We need to add 28 and 23.

  28  Add 8+3, which is 11. So, add a one in the tens place.

+ 23  2+2+1=5, so put that in the tens place.

Answer:

its (3x²+8)(x-5)

Step-by-step explanation:

3x² * x = 3x³.

3x² * -5 = -15x².

8 * x = 8x.

8 * -5 = -40.

The completely factored form of her polynomial is (3x² + 8)(x - 5).

"Factorization of polynomials expresses a polynomial with coefficients in a given field or in the integers as the product of irreducible factors with coefficients in the same domain."

Given polynomial is:

3x³ – 15x² + 8x - 40

= 3x²(x - 5) + 8(x - 5)

= (3x² + 8)(x - 5)

Answer:

J(-5,3) K(-1,-2) L(3,4)

Step-by-step explanation:

Reflections over the y axis make the x its opposite. 5 would change to -5, 1 would change to -1, and -3 would change to 3.

When a shape is reflected, it must be reflected across a line.

See attachment for the graph of the image of JKL

The coordinates are given as:

[tex]\mathbf{J = (5,3)}[/tex]

[tex]\mathbf{K = (1,-2)}[/tex]

[tex]\mathbf{L = (-3,4)}[/tex]

The rule of reflection across the y-axis is:

[tex]\mathbf{(x,y) \to (-x,y)}[/tex]

So, the image of the reflection is:

[tex]\mathbf{J'= (-5,3)}[/tex]

[tex]\mathbf{K'= (-1,-2)}[/tex]

[tex]\mathbf{L'= (3,4)}[/tex]

Answer:

x = - 2, x = 9

Step-by-step explanation:

Given

f(x) = [tex]\frac{x^2-9x}{x^2-7x-18}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the values that x cannot be.

x² - 7x - 18 = 0

(x - 9)(x + 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 9 = 0 ⇒ x = 9

The excluded values are x = - 2, x = 9

Answer:

.909 (ROUNDED)

Step-by-step explanation:

In order to do this all you need to do is divide the number with the number you got this year, 1914, and with the number last year.

1914-174=1740

1740 was the amount they got last year

Now you want to find the percent difference between the two.

1740/1914=.909090 (Repeats)

So the percent increase would be

.909090

.101010

Step-by-step explanation: If someone went shopping for a scooter and it was $49.99 dollars but saw a skateboard for $14.99, they would choose the skateboard because it’s cheaper. If someone else went to the store because they wanted a skateboard but then they saw a scooter for $23.99 and a bike for $19.99 there is a 50% chance they will choose the cheaper one.

The probability is given by the equation P = 12.3 %

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle be P

Now , the equation will be

Let the probability of selecting a person owing a scooter A = 30 %

Let the probability of selecting a person owing a scooter A = 0.3

Let the probability of selecting a person owing a skateboard and bicylce be B = 41 %

Let the probability of selecting a person owing a skateboard and bicylce be B = 0.41

Now ,

Probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle P = probability of selecting a person owing a scooter A x probability of selecting a person owing a skateboard and bicylce B

Substituting the values in the equation , we get

Probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle P = A x B

Probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle

P = 0.3 x 0.41

P = 0.123

Hence , the probability is P = 12.3 %

Answer:

y=  3x + 8

Step-by-step explanation:

y = mx + b

m = 3 inches of water added each day

x = 8 inches of water at start

y=  3x + 8 is the required equation.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, Shannon's rain-catcher has 8 inches of water in it. Each day, 3 inches of water are added to the rain-catcher.

We have,

m = 3 inches of water added each day

x = 8 inches of water at start

Converting in y = mx + b, we get,

Answer:

Adults $10

Child: $6

Step-by-step explanation:

I took the test

The price of an adult ticket and the price of a child ticket are $12 and $13.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

On the first night,

the Movie House Theater sold 7 adult tickets and 11 child tickets for $227.

On the second night, they took in $150 by selling 6 adult tickets and 6 child tickets.

Let x be the number of tickets sold to an adult and y be the number of tickets sold to a child.

According to the question,

7x + 11y = 227   equation 1

and 6x + 6y = 150,

Simplifying,

x + y = 25   equation 2

Now, we have a system of equations.

7x + 11y = 227   equation 1

x + y = 25   equation 2

From the equation 2 we have,

y = 25 - x

Substitute the value of y to the equation 1,

7x + 11(25-x) = 227

7x + 275 - 11x  = 227

275 - 227 = 4x

x = 48/4

x = 12

Then y = 25 - 12

y = 13.

Therefore, the prices of ticket for adult's and children are $12 and $13 respectively.
