Answer:

111 cars

Step-by-step explanation:

30% of 78 is

78×30%=78×0.3=23.4

Cars needed to sell

78+23.4=111.4

Unless we can't have 0.4 of a car, we need to round that number, so 111.4≈111

The number of cars the dealership need to sell in May to reach their goal is 101.4 cars.

Given the following data:

To find the number of cars the dealership need to sell to reach their goal:

Mathematically, percentage increase is given by the formula:

[tex]Perecent\;increase = \frac{New\;value - Old\;value}{Old\;value} \times 100[/tex]

Substituting the given parameters into the formula, we have;

[tex]30 = \frac{New\;value -78}{78}\times 100\\\\2340=100New\;value -7800\\\\100New\;value = 7800+2340\\\\100New\;value=10140\\\\New\;value=\frac{10140}{100}[/tex]

New value = 101.4 cars

Answer:

The zeros are x = 1 and x = 3

In the picture attached, the graph of the function is shown. The zeros are those points where h(x) intersect x-axis.

Step-by-step explanation:

Given the expression:

x² - 4x + 3

Rewrite -4x term:

x² - x - 3x + 3

Take x as common factor in the first terms, and -3 in the last terms:

120 cm^2

Step-by-step explanation:

area of a rhombus is pq/2

that means that the product of the two diagonals divided by 2 is the area of the rhombus.

so that means one diagonal is 24 and one is 10, (we are given what half of both diagonals are so just multiply by 2)

now put it in the formula

24x10 = 240

now divide by 2

240/2 = 120

Answer:

Step-by-step explanation:

Area of polygon = area of square + area of triangle

Square:

Side = 12 cm

Area of square  = side *side

                          = 12 * 12

                          = 144 sq.cm

Triangle:

base (b) = 12 cm

Height h = 19 cm

[tex]Area =\frac{1}{2}bh\\\\=\frac{1}{2}*12*19\\[/tex]

= 6 * 19

= 114 sq.cm

Area of polygon = 144 + 114 = 258 square cm

Answer: $9362.36

Step-by-step explanation:

A = P(1 + r/n)^nt

After 18 years, this investment will be worth of  $9,379.45.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

Compound interest is calculated by multiplying the initial principal amount (P) by one plus the annual interest rate (R) raised to the number of compound periods (nt) minus one. That means, CI = P[(1 + R)ⁿˣ – 1] Here,

P = Initial amount

R = Annual rate of interest as a percentage

n = Number of compounding periods in a given time

Given,  Five thousand dollars is invested at an interest rate of 3.5% compounded quarterly.

From the above formula of compound interest

Total amount  A = P(1 + r/n)^nt

In our case

p = 5000

r = 3.5%

t = 18 years

Thus,

Total amount = 5000( 1 + 3.5%)^18

Total amount = $9,379.45

therefore, this investment will be worth $9,379.45 after 18 years.

Step-by-step explanation:

Answer:

5 x 18 = 5 x 2 x 9

5 x 18 = 90

Step-by-step explanation:

For the first equation, notice that 18 is broken into 9 and an unknown.

This can be written as:

18 ÷ 9 = ?

Well, 18 divided by 9 equals 2.

18 ÷ 9 = 2

We can use this to answer the second equation.

Instead of trying to multiply 5 and 18, multiply 5 and 2 first.

5 x 18 = 5 x 2 x 9

5 x 18 = 10 x 9

Now, just multiply 10 and 9.

5 x 18 = 10 x 9

5 x 18 = 90

Therefore, the product of 5 and 18 is 80.

Answer:

Step-by-step explanation:

Given

3(x - 2) = 22 - x ← distribute parenthesis on left side

3x - 6 = 22 - x ( add x to both sides )

4x - 6 = 22 ( add 6 to both sides )

4x = 28 ( divide both sides by 4 )

x = 7

An equation can either have a solution, no solution or infinite many solutions

The equation has one solution.

The equation is given as:

[tex]\mathbf{3(x - 2) = 22 - x}[/tex]

Open bracket

[tex]\mathbf{3x - 6 = 22 - x}[/tex]

Collect like terms

[tex]\mathbf{3x + x = 6 + 22}[/tex]

Evaluate like terms

[tex]\mathbf{4x = 28}[/tex]

Divide both sided by 4

So i checked the question online and i believe the part "a scale where 12 inch corresponds to 6 feet" should be "a scale where 1/2 inch corresponds to 6 feet"

In that case, a scale where 1/2 inch corresponds to 6 feet means

scale = 1inch to 12 feet

Answer:

21.35 [tex]ft^{3}[/tex]

Step-by-step explanation:

It is given that the box is a triangular prism.

Side of Base of prism = 7 ft

Height of Base of prism = 6.1 ft

Area of a triangle is given as:

[tex]B = \dfrac{1}{2} \times \text {Base} \times \text{Height}[/tex]

[tex]\Rightarrow \dfrac{1}{2} \times 7 \times 6.1\\\Rightarrow 21.35\ ft^{2}[/tex]

Volume of a prism is:

[tex]V = B \times h[/tex]

B is the area of base of prism

h is the height of prism

Here, h = 1 foot

So, V = 21.35 [tex]\times[/tex] 1

Volume of prism is = 21.35 [tex]ft^{3}[/tex]

Sand required to fill the triangular prism shape box is 21.35 [tex]ft^{3}[/tex].

Answer:

(x - 3)^2 + (y - 5)^2 = (√89)^2

Step-by-step explanation:

Well if you estimate, you can see that the circle touches one point at (-5, 0) and the center is at about (3, 5).

The standard equation for the circle is (x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center.

So, you can start by plugging in the center. (x - 3)^2 + (y - 5)^2 = r^2

Now, all you have to do is find the radius.

You can do this by connecting the point (-5, 0) to the center.

You will have to use the distance formula:

√(-5 - 3)^2 + (0 - 5)^2 = √64 + 25 = √89

The final equation will be (x - 3)^2 + (y - 5)^2 = (√89)^2

This is the general idea, but my answer may not be correct, so check my steps.

Step-by-step explanation:

You should know that the volume of a straight circular cone is equal to:

Where:

r = radius.

h = height.

Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:

When clearing you get:

By replacing the data you get:

Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:

The price of a 12-minute phone call is  $4.2.

We have given that,

The price of a 5-minute phone call is $1.75.

We have to determine, the price of a 12-minute phone call.

A price is the (usually not negative) quantity of payment or compensation given by one party to another in return for goods or services.

We first 1.75 divided by 5 which gives you .35

That is,

[tex]\frac{1.75}{5} =0.35[/tex]
