can someone help me solve this

Answers

Answer 1

You are right before it’s 4 months.

Answer 2

Write an expression for both companies
m stands for the number of months
⇒ Company A has a $20 signing fee and charges $40 monthly. Signing fee will be the constant, because it's not influenced by the number of months. 40 will be the coefficient of m. The expression will be 20 + 40m
⇒ Company B has no signing fee and charges $45 monthly. 45 will be the coefficient of m, because the total charge is influenced by the number of months. The expression will be 45m

Determine the number of months
For both costs being equal, write an equation that equalizes both expression
45m = 20 + 40m

solve for m
45m - 40m = 20
5m = 20
m = 20/5
m = 4
For both costs being equal, it needs 4 months

The annual inflation rate is 3.5% per year. If a movie costs $7.50, determine which of the following graphs best models the change in price, with respect to time, of the movie ticket.

Answers

Let's model the cost by the following exponential function:
c (t) = (7.50) * (1.035) ^ t
Where,
c (t): cost of the movie after t years.
7.50: initial cost of the movie in $
1,035: annual percentage increase due to inflation.
t: time in years.
for t = 0 We have:
c (t) = (7.50) * (1.035) ^ 0

Sylvia has 3/4 of a yad of paper to wrap candles. It takes 1/8 of a yard of paper to wrap each candle. How many candles can Sylvia Wrap?

Answers

Sylvia can wrap 6 candles.

To find out how many candles Sylvia can wrap with 3/4 of a yard of paper, we need to divide the total paper by the paper needed for each candle. Since it takes 1/8 of a yard to wrap one candle, we can find the number of candles by dividing 3/4 by 1/8:

3/4 ÷ 1/8 = 3/4 x 8/1 = 6 candles

Therefore, Sylvia can wrap 6 candles with the available paper.

The vertices of triangle ABC are A(2,3), B(–1,2), and C(3,1). If ΔDEF ∼ ΔABC and DE = 4AB, what is the length of EF? √10

Answers

If the length is 4 times from DE=4AB then the corresponding length of EF which is BC is also 4 times larger. Length of BC=sqrt((2-1)^2+(-1-3)^2)=sqrt of 17 Hence, length of EF is 1/4 of sqrt 17. Hope it helps

Answer:

The length of EF is [tex]4\sqrt{17}[/tex] units.

Step-by-step explanation:

The vertices of triangle ABC are A(2,3), B(–1,2), and C(3,1).

Using distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]BC=\sqrt{(3+1)^2+(1-2)^2}=\sqrt{17}[/tex]

It is given that ΔDEF ∼ ΔABC.

If two triangles are similar then the corresponding sides are proportional.

[tex]\frac{AB}{DE}=\frac{BC}{EF}[/tex]

[tex]\frac{AB}{4AB}=\frac{BC}{EF}[/tex] (DE = 4AB)

[tex]\frac{1}{4}=\frac{BC}{EF}[/tex]

[tex]EF=4\times BC[/tex]

[tex]EF=4\times \sqrt{17}[/tex]

[tex]EF=4\sqrt{17}[/tex]

Therefore the length of EF is [tex]4\sqrt{17}[/tex] units.

Each of the two congruent sides of an isosceles triangle is 8 inches less than twice the base.the perimeter of the triangle is 74 inches ,what is the length of the base

Answers

if base is x
congruent side = 2x-8
perimeter=2 congruent sides +base

2(2x-8)+x=74
4x-16+x=74
5x=58
x=11.6

length of the base is 11.6 inches

Final answer:

The length of the base of the isosceles triangle is 18 inches.

Explanation:

Let the length of the base be 'b' inches. According to the given information, each of the congruent sides of the isosceles triangle is 8 inches less than twice the base. So, the length of each congruent side is (2b - 8) inches.

The perimeter of the triangle is the sum of all three sides, which is given as 74 inches. So, we can write the equation:

(2b - 8) + (2b - 8) + b = 74

Simplifying the equation, we get:

5b - 16 = 74

5b = 90

b = 18

Therefore, the length of the base is 18 inches.

A bicycle manufacturer is reducing the number of spokes on each bicycle wheel by 4. a wheel on one of the other companies new cross-country bike has 32 spokes. Which equation could be used to determine the number of spokes that a wheel on a cross country bike used to have?

Answers

32spokes+4spokes that's the equation

The original number of spokes on the wheel was 36.

The question seeks to determine the original number of spokes on a bicycle wheel, given that the current number is 32 after reducing by 4. To find the original number of spokes, we need to use a simple algebraic equation that adds the removed spokes back to the current number.

Let x represent the original number of spokes. The manufacturer has reduced the number of spokes by 4, so we subtract 4 from the original number to get the current number of spokes. The equation that represents this scenario is:

x - 4 = 32

To find the original number of spokes, we need to solve for x:

x = 32 + 4

x = 36

Therefore, the original number of spokes on the wheel was 36.

An app developer projects that he will earn $22.00 for every 8 apps downloaded. Write an equation to represent the proportional relationship between the number of apps and the total earnings.

Answers

$the answer is 22/8 = x/1

Answer:

y = ($2.750 / app) . x

Step-by-step explanation:

Let's call

x = number of appsy = earned money

There is a linear relation between x and y, that follows the general form:

y = a . x + b

where

a is the slope

b is the y-intercept

The slope is:

Δy / Δx = $22.00 / 8 app = $2.750 / app

The, we have

y = ($2.750 / app) . x + b

When x = 0 (no app has been sold), y = 0 (no money has been earned).

0 = ($2.750 / app) . 0 + b

b = 0

The equation representing the proportionality between x and y is:

y = ($2.750 / app) . x

The shaded area represents a cement walkway around a pool. State the algebraic expression that represents the difference between the outside perimeter of the walkway and the perimeter of the pool.

Answers

Large perimeter : 2(2x+12)+2(2x-1+7+7)=8x+50
Smaller perimeter : 2(2x-1)+2(12)=4x+22

Large perimeter - smaller perimeter = 4x+28

The difference between the outside perimeter of the walkway and the perimeter of the pool in algebraic expression is (2x + 14).

How to solve perimeter of rectangle?

Pool:

Length = 2x - 1

Width = 12

The perimeter of the pool = 2(length + width)

= 2{(2x - 1) + 12}

= 2(2x - 1 + 12)

= 2(2x + 11)

= 4x + 22

Outside perimeter of the walkway:

Length = (2x - 1) + x

= 3x - 1

Width = 12 + 7

= 19

The perimeter of the walkway = 2(length + width)

= 2{(3x - 1) + 19}

= 2(3x - 1 + 19

= 2(3x + 18)

= 6x + 36

Difference between the outside perimeter of the walkway and the perimeter of the pool = The perimeter of the walkway - The perimeter of the pool

= (6x + 36) - (4x + 22)

= 6x + 36 - 4x - 22

= 2x + 14

Hence, (2x + 14) is the expression which represents the difference between the perimeter of the walkway and the perimeter of the pool.
