Alan Is saving money to buy a game. So far he has saved $20, which is four-fifths of the total cost of the game. How much does the game cost?

Answer:

B

Step-by-step explanation:

A monomial (mono -> one) is an expression with 1 term

A is a trinomial (or polynomial), B is monomial, C is binomial.

Step-by-step explanation:

When b = 5,

4b² = 4(5)² = 4 * 5 * 5 = 100.

Answer:

100 is the right answer.

Step-by-step explanation:

Given that b=5

4b² = 4(5)² = 4×25 = 100

Answer:

[tex]12 * (2 - 3) + (4 * 2)[/tex]

Step-by-step explanation:

Follow PEMDAS for the given answer.

PEMDAS is the order of operation, and is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

Reverse solve the answer so that the result is the question.

First, solve the parenthesis:

12 * (2 - 3) + (4 * 2)

12 * (-1) + 8

Next, multiply 12 and -1 together:

12 * -1 = -12

Finally, add:

-12 + 8 = -4

12 * (2 - 3) + (4 * 2) is your answer.

[tex]12 \times (2 - 3) + (4 \times 2)[/tex]

Step-by-step explanation:

Add parentheses to the following equation to make it true.

[tex]12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times (2 - 3) + (4 \times 2)[/tex]

[tex] = 12 \times ( - 1) + 8[/tex]

[tex] = - 12 + 8[/tex]

[tex] = - 4[/tex]

Answer:

C

Step-by-step explanation:

Answer:

We conclude that

(g o f) (4) = 9

Hence, option C is correct.

Step-by-step explanation:

Given

f(x) = -x³

g(x) = |1/8x - 1|

To determine

(g o f) (4) = ?

Using the formula

(g o f) (4) = g[(f(4)]

first we need to determine f(4)

so substituting x = 4 into f(x) = -x³

f(x) = -x³

f(4) = -(4)³ = -64

so

(g o f) (4) = g[(f(4)] = g(-64)

so substitute x = -64 in g(x) = |1/8x - 1|

[tex]g\left(x\right)=\left|\frac{1}{8}x-1\right|[/tex]

substitute x = -64

[tex]g\left(-64\right)=\left|\frac{1}{8}\left(-64\right)-1\right|[/tex]

            [tex]=\left|-\frac{1}{8}\cdot \:64-1\right|[/tex]

            [tex]=\left|-8-1\right|[/tex]

            [tex]=\left|-9\right|[/tex]

Apply absolute rule: |-a| = a

            [tex]=9[/tex]

Therefore, we conclude that

(g o f) (4) = 9

Hence, option C is correct.

Answer:

12w + 140 = 356

Step-by-step explanation:

Her goal is to save up 356$. She already has 140$, and wants to save 12$ per week. We're trying to find how many weeks it would take.

You must multiply 12 by the number of weeks, which elimates the first two equations. We're also trying to add together 140 and the 12x because we want the total to ADD to 156.

Answer:

The answer is below

Step-by-step explanation:

The question is not complete but i would show how to solve.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, rotation, translation and reflection.

Dilation is the enlargement or reduction in the size of a figure.

a) If an point A(x, y) is dilated by a factor k, the new coordinate is A'(kx, ky). From the above options the ones that represent dilation is (x, y) → (0.5x, 0.5y)  and (x, y) → (2x, 2y) . If the object is reduced then the correct option is (x, y) → (0.5x, 0.5y)   while if the object is enlarged the correct option is (x, y) → (0.5x, 0.5y)

b)Dilation is the enlargement or reduction in the size of a figure by a factor k. If k < 1, then it is a reduction and if k > 1, it is an enlargement.

Since Triangle XYZ is dilated with the origin as the center of dilation using the rule (x, y)⇒(0.5x, 0.5y) to create Triangle X’Y’Z’, since the factor is less than 1(0.5 < 1), it is a reduction. Hence Triangle X’Y’Z’ is smaller than Triangle XYZ, because the scale factor is less than 1

c) The dilation creates a smaller figure hence the factor of dilation should be less than 1.

Answer:

80%

Step-by-step explanation:

The actual value measurement = 4

Estimated value of the measurement= 4.8

percent error= (Estimated value - actual value) ×100%

= (4.8-4)×100%

=0.8×100%

=80%

Hence, Isaiah's percent error is 80%

Answer:

1) The roots of the equation Y = -x² - 12·x - 37 are x = -6 - √73 and -6 + √73

2) The factors of the function Y = -x² - 12·x - 37 are (x + (-6 - √73)) and (x - (-6 + √73))

3) The vertex is (-6, -1)

4) The Y-intercept is (0, -37)

5) The axis of symmetry is x = -6

6) The parabola opens downward

7) The maximum point is (-6, -1)

8) The graph of the function created with Microsoft Excel is attached

9) The domain of the function is -∞ < x < ∞

10) The range of the function is -∞ < Y ≤ -1

Step-by-step explanation:

The given function is Y = -x² - 12·x - 37

1) The roots of the equation Y = -x² - 12·x - 37 is given as follows;

0 = -x² - 12·x - 37

∴ -x² - 12·x - 37 = 0

The roots are;

x = (12 ± √((-12)² - 4 × 1 × (-37)))/(-2)

∴ x = -6 - √73 and -6 + √73

2) The factors are (x + (-6 - √73)) and (x - (-6 + √73))

3) The vertex is given by h = -b/(2·a) = 12/(2) = -6

k = c - b²/(4·a) = -37 - 144/(-4) = -1

The vertex = (h, k) = (-6, -1)

4) The intercept with the "Y" axis is given when x = 0, therefore, the y-intercept is (0, -37)

5) The axis of symmetry can be found at the vertex or the line x = -6

6) The sign of the coefficient of x² is negative therefore, the parabola opens downward

7) The maximum point is given as follows;

At the maximum point, dY/dx = d(-x² - 12·x - 37)/dx = -2·x - 12 = 0

x = 12/(-2) = -6, which is the vertex, therefore Y = -(-6)² - 12×(-6) - 37 = -1

The maximum point is the vertex (-6, -1)

8) Please find attached the graph of the function created with Microsoft Excel

9) The domain of the function is -∞ < x < ∞

10) The range of the function is -∞ < Y ≤ -1

Answer:

45

Step-by-step explanation:

The formula for finding the longest size of a right angle is

[tex]c^{2} = a^{2} + {b}^{2}[/tex]

a = 28, b = ? and c = 53;

Therefore, if you make b the subject of the formula, you will have

[tex]b = \sqrt{ {c}^{2} - {a}^{2} } [/tex]

And after plugging the value of c=53 and a=28, b is gotten to be 45

Answer:

8 more times than

Step-by-step explanation:

We are told in the above question that:

Jason and Monica each need to put 1 gallon of water into a pot.

It is important to note that:

1 liquid gallon = 16 cups

1 liquid gallon = 8 liquid pints

For Jason

Jason has a measuring cup that holds 1 cup.

1 liquid gallon = 16 cups

In order to fill the pot, Jason has to use the cup 16 times

For Monica

Monica has a measuring cup that holds 1 pint.

Monica has to fill the pot using her measuring cup 8 times

How many more times does Jason need fill the measuring cup than Monica?

This is calculated as:

16 times - 8 times

= 8 times

Therefore, Jason needs to fill the measuring cup 8 more times than Monica

Complete question :

Jorge pays $13 per month to join the track club. He pays $6.00 every time he rents a discus. The equation C = 13m + 6.00n. Represents the total cost of throwing at the club, where m is the number of months, and n is the number of practice sessions. What is the total cost per year for Jorge to go to the club 20

The 4- in the equation seems to be a typographical error and instead should have been something like this :

C = 13m + 6.00n

Answer:

$276

Step-by-step explanation:

Given :

Cost of throwing, C = 13m - 6n

m = Number of months ; n = number of practice sessions

n = 20 ; m = 1 year = 12 months

C = 13(12) + 6(20)

C = 156 + 120

C = $276
