Step-by-step explanation:

-4(-5h-4)=2(10h+8)

-4 will multiply the ones in the bracket beside it

-4*-5h=20h

-4*-4=16

20h+16=

2 will multiply the ones in the bracket beside it

2*10h=20h

2*8=16

20h+16=

so we have 20h+16=20h+16

Greetings from Brasil...

Here's our problem:

[tex]\large{\frac{12^{3}}{12^{7}}}[/tex]

From potentiation properties:

Mᵃ ÷ Mᵇ = Mᵃ⁻ᵇ

division of power of the same base: I repeat the base and subtract the exponents

So, in our problem

[tex]\large{\frac{12^{3}}{12^{7}}}[/tex] = 12³ ÷ 12⁷

12³ ÷ 12⁴ = 12³⁻⁷

12⁻⁴

We also know about another property: P⁻ⁿ = (1/Pⁿ) so

12⁻⁴ = (1/12⁴)

Step-by-step explanation:

Here,

We have,

[tex] { \sin }^{2} theta \: + {cos}^{2}theta = 1[/tex]

[tex] {cos}^{2} \: theta = 1 - {sin}^{2} \: theta[/tex]

[tex]cos \: theta = \sqrt{1 - { \sin }^{2}theta } [/tex]

So, it's true; and it lies in quadrant 1 and 4.

The reason according to the "CAST" rule cos theta is in 1st and 3rd quadrant cos theta is positive.

Answer:

n = 0

Step-by-step explanation:

6 = 1 - 2n + 5

6 = 6 -2n

0 = -2n

n = 0

The value of n after solving the given equation 6 = 1 - 2n + 5 is the number, n = 0.

Given an equation:

6 = 1 - 2n + 5

It is required to find the value of n.

In order to find the value of n, the variable n has to be isolated to one side of the equation with the constant on the other.

Here, the variable is n.

The equation can be written as:

6 = -2n + 6

Subtract 6 from both sides.

0 = -2n

Now, divide both sides by -2.

0 = n

Hence, the value of n is 0.

Answer:

[tex]C = 700+0.22m[/tex]

Domain is [0,500] or [tex]0 \leq m\leq 500[/tex]

Step-by-step explanation:

We are given that:

Cost of cell phone is $700.

Cost per minute for the first 500 calls is $0.22 per minute.

To find:

Function to model total cost of the cell phone bill for the first 500 minutes.

And domain of the function = ?

Solution:

Here, Total Cost is the sum of cost of cell phone, plus the cost of calls.

Total Cost = Cost of cell Phone + Cost of calls

We have the cost of cell phone as $700.

and cost of calls is $0.22 per minute up to 500 minutes.

Let the number of minutes for the calls is m. (m [tex]\leq[/tex] 500)

So, cost for m number of minutes of calls = m [tex]\times[/tex] cost per minute

cost for m number of minutes of calls = [tex]0.22 \times m[/tex]

Let the Total Cost be represented as C.

So, we can write the cost function as:

[tex]C = 700+0.22m \ \{0\leq m\leq500\}[/tex]

Domain of a function is the valid input value to the function for which the output is defined.

Here, the domain is [0, 500] i.e. 0 and 500 are inclusive.

So, the answer is:

[tex]C = 700+0.22m[/tex]

Domain is [0,500] or [tex]0 \leq m\leq 500[/tex]

Answer:

D. AO

Step-by-step explanation:

The radius can be made with a line from a point in the circumference (end) to the middle.

Point A is on the circumference. Point O is in the middle. So, line segment AO is the radius.

The radius of a circle is a line drawn from the center of the circle to any point on the circumference of the circle.

The radius of the circle are AO, CO and BO.

From the attached diagram of the circle, we have:

[tex]O \to[/tex] center

There are three lines from center O to the circumference of the circle. The three points are: A, C and B.

This means that the radius of the circle are AO, CO and BO.

Hello! Your answer is below... Remember : h = height and v = volume

Answer:

H = 15.35 cm

V = 690.75 m^

Step-by-step explanation:

(H= height, V = volume, ^= square, √ = square root )

1. divide 9/2

=4.5 cm

2. use the pythagorean theorem

H=√16^-4.5^

H=15.35

if your looking for volume

1. use the formula for volume of the pyramid which is:

1/3 x base area x height

or

base area x height /3

2. then you substitute

1/3 x (9)(15) x 15.35

or

(9)(15) x 15.35 /3

V= 690.75 m^

Answer:

height =  h = 13.4 cm

volume =  V = 602.8 cm³

Step-by-step explanation:

area of a square base = 15 cm x 9 cm = 135 cm²

slant height of pyramid = 16m

solving height:   (see attached image)

first step is to take the diagonal base:

side of base 15 =  15 / 2 = 7.5cm

side of base 9 = 9 / 2 = 4.5m

diagonal base = sqrt ( 7.5² + 4.5²) = 8.75 cm

therefore

height² = slant height² - diagonal base²

h² = 16² - 8.75²

h = 13.4 cm

solving the volume:

V = 1/3 * area of square base * h

V = 1/3 * 135 * 13.4

V = 602.8 cm³

Answer:

The answer is 24

Step-by-step explanation:

If the restaurant fee is $7.5 and the price is $14 per pizza, she has $52.5 to spend on the pizzas after we deduct the restaurant fee.

That means she can get 52.5 / 14 = 3.75 pizzas.

I hope this answer helps.

The total slices she can afford is 30 and this can be determined by using the unitary method and forming the linear equation.

Given :

The following steps can be used to determine the total slices she can afford:

Step 1 - Total cost to order one pizza is given by:

= 7.5 + 14

= $21.5

Step 2 - Let the total number of pizzas she can order be 'x'. So, the delivery fee plus the cost of the pizzas under $60 is represented by the equation:

14x + 7.5 = 60

14x = 52.5

x = 3.75

Step 3 - Now, according to the given data if one pizza contains 8 slices then 3.75 pizza contains:

[tex]= 3.75\times 8[/tex]

= 30 slices

The total slices she can afford is 30.

Answer:

The amount each took home was 20 unit currency.

Step-by-step explanation:

We are given that Seven apple women, possessing respectively 20, 40, 60, 80, 100, 120, and 140  apples, went to market and sold all their apples at the same price, and each  received the same sum of money.

Formula  : [tex]a \times n + (n - 1)[/tex], [tex](a + b)\cdot n + (n - 2)[/tex], [tex](a + 2 \cdot b) \cdot n + (n - 3)[/tex], [tex](a + 3 \cdot b) \cdot n + (n - 4)[/tex], [tex](a + 4 \cdot b) \cdot n + (n - 5)[/tex], [tex](a + 5 \cdot b) \cdot n + (n - 6)[/tex], [tex](a + 6 \cdot b) \cdot n + (n - 7)[/tex]

[tex]a \cdot n + (n - 1) = 20[/tex]

[tex](a + b) \cdot n + (n - 2)=40[/tex]

[tex](a + 2 \cdot b) \cdot n + (n - 3) = 60[/tex]

[tex](a + 3 \cdot b) \cdot n + (n - 4) = 80[/tex]

[tex](a + 4 \cdot b) \cdot n + (n - 5) = 100[/tex]

[tex](a + 5 \cdot b) \cdot n + (n - 6) = 120[/tex]

[tex](a + 6 \cdot b) \cdot n + (n - 7) = 140[/tex]

On solving :

n = 7, a = 2, b = 3

So,

[tex]2 \times 7 + 6 = 20[/tex]

[tex]5 \times 7 + 5=40[/tex]

[tex]8 \times 7 + 4 = 60[/tex]

[tex]11 \times 7 + 3 = 80[/tex]

[tex]14 \times 7 + 2 = 100[/tex]

[tex]17 \times 7 + 1 = 120[/tex]

Based on market pricing if groups of apples are sold at 1 unit currency for 7, and extras are sold for 3 unit currency per extra 1, we have the amount :

2×1 + 6×3 = 20

5×1 + 5×3=20

8×1 + 4×3 = 20

11×1 +  3×3 = 20

14×1 + 2×3 = 20

17×1 + 1×3 = 20

20×1 = 20

Therefore, the amount each took home was 20 unit currency.

Answer:

Option (C)

Step-by-step explanation:

To determine the population we use the formula,

[tex]P_n=P_0(1+r)^{n}[/tex]

Where [tex]P_n[/tex] = final population

[tex]P_0[/tex] = Initial population

r = percentage growth

Now we substitute these values in the formula,

[tex]7921=7547(1+r)^1[/tex]

[tex]\frac{7921}{7547}=(1+r)[/tex]

r = 1.0496 - 1

r = 0.0496

r = 0.05

Therefore, percentage growth of the population of Stark county is 5%.

Option (C). will be the answer.
