Step-by-step explanation:

2(Mr stack's speed) = Coach Pugh's speed - 5mph

Answers

4/3
Remember if two lines are perpendicular, the product of their slopes are -1

Answer:

4/3        equation however is y = 4/3x + 3 (the plus three can be changed to anything

Step-by-step explanation:

Lemme just tell you this:

If you are looking for the equation of a completely perpendicular line,

just find the COMPLETE OPPOSITE of the current slope. -3/4x would be 4/3 because it is the opposite in terms of positive or negativeness and the way the numbers are arranged. Change the sign, flip the number, and you are good to go.

Step-by-step explanation:

Here,

The adjacent to Ф = 13The hypotenuse = 18

so

cos Ф = adjacent/hypotenuse

A company that teaches self-improvement seminars is holding one of its seminars in Belmont. The company pays a flat fee of $250 to rent a facility in which to hold each session. Additionally, for every attendee who registers, the company must spend $4 to purchase books and supplies. Each attendee will pay $14 for the seminar. Once a certain number of attendee register, the company will be breaking even. How many attendees will that take?

Answers

Answer:

Step-by-step explanation:

250 for place  4 for books each.

If they charge 14 per person, 4 of that goes for the books and 10 will be applied to the rental fee.

250/10= 25 people to break even. Any people beyond that  is a profit of 10.00 since the other 4 will still go to the books.

Jasim has invested 600 dinars in a business at the rate of 4 % for 3 years. Find his

i- simple interst ?


ii- total amount after 3 years ​

Answers

Answer:

1) Simple interest is 72 dinars

2) Total amount after 3 years is 672 dinars.

Step-by-step explanation:

Principal Amount P = 600 dinars

Interest Rate= 4% = 0.04

Time = 3 years

i) Simple Interest

The formula used to calculate interest is [tex]I=P\times r \times t[/tex]

Putting values and finding interest

[tex]I=P\times r \times t\\I=600\times 0.04 \times 3\\I=72[/tex]

So, simple interest is 72 dinars

ii) Total amount after 3 years ​

The formula to calculate total amount is: [tex]A=P(1+rt)[/tex]

Putting values and finding future amount A

[tex]A=P(1+rt)\\A=600(1+(0.04*3))\\A=600(1+0.12)\\A=600(1.12)\\A=672[/tex]

So, Total amount after 3 years is 672 dinars.

a distributor wants to make 1000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?

Answers

Answer:

200 pounds 20% raisins

800 pounds 5% raisins

Step-by-step explanation:

Let number of 5% be x

and number of 20% be y

x + y = 1000

Also;

5% of x + 20-% of y = 8% of 1000 pounds

= 0.05x + 0.2y = 80

From i , x = 1000-y

0.05(1000-y) + 0.2y = 80

50-0.05y + 0.2y = 80

0.15y = 30

y = 200

x = 1000 - y

= 1000-200 = 800

He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.

Given that,

A distributor wants to make 1000 pounds of trail mix that is 8% raisins.

He will use a mix that is 5% raisins and a mix that is 20% raisins.

We have to determine,

How many pounds of each should he use.

According to the question,

Let number of 5% raisins be x,

And number of 20% raisins be y.

Then,

He will use a mix that is 5% raisins + A mix that is 20% raisins = Distributor trail mix.

[tex]x + y = 1000[/tex]

And,

He will use a mix that is 5% raisins of x + and a mix that is 20% raisins of y =  1000 pounds of trail mix that is 8% raisins.

5% of x + 20% of y = 1000 of 8% raisins

[tex]0.05 x+ 0.20y = 80[/tex]

On solving both the equation,

[tex]x + y =1000\\\\x = 1000-y[/tex]

Substitute the value of x in the equation 2,

[tex]0.05 (1000-y) + 0.20y = 80\\\\0.05 \times 1000 - 0.05y + 0.20y = 80\\\\50 + 0.15y = 80\\\\0.15y = 80-50 \\\\0.15y = 30\\\\y = \dfrac{30}{0.15}\\\\y = 200[/tex]

Substitute the value of y in the equation 1,

[tex]x + y = 1000\\\\x + 200 = 1000\\\\x = 1000-200\\\\x = 800[/tex]

He will use x = 800 pounds a mix that is 5% raisins and y = 200 pounds for a mix that is 20% raisins.

Hence, He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.

Answers

Answer:

First is 5/2

second is 1

Answer:

1. A. slope = 5/2

2. A. slope = 1

Step-by-step explanation:

To find the slope you can input the x and y values of two points into this expression: [tex]\frac{y2 -y1}{x2 - x1}[/tex]

1. To find the slope, I'm going to use points (2, 3) and (4, 8). Let's input them into the expression:

[tex]\frac{8-3}{4-2}[/tex]

Simplify:

8 - 3 = 5

4 - 2 = 2

The slope is 5/2.

2. To find the slope, I'm going to use points (0, 0) and (1, 1). Let's input them into the expression:

[tex]\frac{1-0}{1-0}[/tex]

Simplify:

1 - 0 = 1

1 - 0 = 1

The slope is 1/1, or just 1.
