Step-by-step explanation:

1 pound of raisins = $2

1 pound of almonds = $5

Let the number of raisins be represented by a

Let the number of almonds be represented by b

We are told in the question that:

Six pounds of a trail mix contains 2 more pounds of raisins than almonds.

a + b = 6 pounds

Hence, Almonds = 2 pounds

Raisins = 4 pounds

The cost of the 6 pounds of trail mix

= 4 × $2 + 2 × $5

=$8 + $10

Answer:

B.   183 degrees.

Step-by-step explanation:

m arc MN = 360 - 107 - 177

= 360 - 284

= 76

m NMK =   76 + 107

= 183

The measure of the arc NMK will be 183°. Then the correct option is B.

The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.

The measure of the angle ∠MLK is 35°.

The major and minor arc is 117x and 107x.

We know that the angle ∠MLK is the half of the difference of the major arc to minor arc.

∠MLK = (arc KN – arc KM) / 2

    35° = (177x - 107x) / 2

    70° = 70x

        x = 1°

Then the measure of the arc KN will be

Arc NK = 177 x 1

Arc NK = 177°

We know that the sum of the arc KN and KMN will be 360°.

mNK + mNMK = 360°

 177° + mNMK = 360°

           mNMK = 360° – 177°

           mNMK = 183°

The measure of the arc NMK will be 183°.

Then the correct option is B.

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

Answer:

The amount Trevor's family pay per minute on shower water is $0.005.

Step-by-step explanation:

The cost of water is,

Cost = $0.20/liter

Amount of water used over the entire month:

Amount of water used = 72 liters

Compute the total water cost as follows:

Total water cost = Amount of water used × Cost

                           = 72 × 0.20

                           = $14.4/liter

The average number of minutes each person showered is:

Average number of minutes = 480 minutes.

The number of people in Trevor's house:

N = 6

Compute the total amount of time the 6 person showered as follows:

Total amount of time = Average number of minutes × N

                                   = 480 × 6

                                   = 2880 minutes

Compute the pay per minute on shower water as follows:

Pay per minute on water = Total water cost ÷ Total amount of time

                                          = $14.4 ÷ 2880

                                          = $0.005

Thus, the amount Trevor's family pay per minute on shower water is $0.005.

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:

[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:

$14

Step-by-step explanation:

Marissa has a Master's degree and earns annual salary of $80,400.

She works 40 hours per week for 48 weeks per year.

Her sister has a Bachelor's degree and earns an average of $58,000 per year.

She works 40 hours per week for 52 weeks per years.

Marissa works for a total of 40 × 48 = 1920 hours a year.

Her hourly wage = [tex]\frac{80,400}{1920}[/tex] = $42 (rounded up to nearest dollar).

Her sister works for a total of 40 × 52 = 2080 hours

Her hourly wage = [tex]\frac{58,000}{2080}[/tex] = $28 (rounded up to nearest dollar)

So Marissa's hourly wage is $42 - $28 = $14 more than her sister's hourly wage.

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.

and 144 its a perfect square (144 = 12²)

It is visible that if we multiply 288 by 1/2, we will obtain a perfect square, but we will do this via a simple equation

288 · X = 144

X = 144 ÷ 288

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
