Answer 1

Answer:

t = [tex]\frac{D-M}{Mr}[/tex]

Step-by-step explanation:

Given

D = M + Mrt ( subtract M from both sides )

D - M = Mrt ( divide both sides by Mr )

[tex]\frac{D-M}{Mr}[/tex] = t

Answer 2

Answer:

t = D/Mr - 1/r or (D - M)/Mr

Step-by-step explanation:

D = M + Mrt

isolate t

D - M = Mrt

(D - M)/M = rt

D/M - 1 = rt

D/Mr - 1/r = t

Beth participated in a free throw contest. she took 10 shots and missed 6 of them. Beth wants to know how to describe the number of baskets she made.what percent of her shots did Beth make?

Answers

Answer:

She made 40% of her shots.

Step-by-step explanation:

First, you would subtract 10 - 6 = 4.

Second, you would make 4/10 a decimal to convert it to a percent by moving the decimal point to places to the right = .40 = 40%.

Your answer is 40% of her shots were made.

Beth made 40 percentage of  shots.

What is percentage?

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

The total number of shots taken by Beth = 10

The missed shots by Beth= 6

The Shots which are made by Beth = 10-6 =4

Patrick has a gas-powered boat that averages 5 miles per gallon of gasoline, and the tank holds 4 gallons. At 2 p.m., he left the dock. At 3 p.m., he was 6 miles west and 8 miles south of the dock. If he continues at this rate, in how many more hours will the tank be out of gasoline? Round to the nearest tenth if necessary.

Answers

Answer:

1 hour

Step-by-step explanation:

Let's assume that Patrick is travelling on a straight line throughout the whole path in order to minimize the distance.

The number of miles that he can travel on a full tank is:

[tex]m = 5\ mpg*4\ gallons\\m=20\ miles[/tex]

The distance travelled by Patrick in one hour (from 2p.m. to 3p.m.) is:

[tex]d^2=6^2+8^2\\d=\sqrt{100}\\ d=10\ miles[/tex]

If he is travelling at 10 miles per hour, and he could travel for a total of 20 miles, then the time remaining before the tank runs out of gasoline is:

[tex]t=\frac{20-10}{10}\\ t=1\ h[/tex]

If he continues at this rate, the gas will last for 1 more hour.

3. Greg is in a car at the top of a roller-coaster ride. The distance, d(t), of the car
from the ground as the car descends is determined by the equation d(t) = 144 - 167,
where t is the number of seconds it takes the car to travel down to each point on theride. How many seconds will it take Greg to reach the ground?

Answers

Answer: 3 seconds

Step-by-step explanation:

Hi, the correct equation is d (t) = 144- 16 t²

So, to answer this question we have to analyze the information given:

When the car reaches the ground the distance, d (t) of the car from the ground is 0.

0 = 144- 16 t²

Solving for t:

16 t² =144

t²=144/16

t²= 9

t = √9

t = 3 seconds

This said, the slope of the equation is 3/4.

I will attach an image of the graph. I put the equation in a graphing calculator.

If you need to graph by hand, first plot the y intercept, (0,2) and then use the slope to find more points. Then, connenct the points with a ruler.

Above are two different models of the same triangular-shaped garden. If the height of the model on the left is 15 cm, what is the height of the model on the right?

Answers

Answer: The height of the model on the right is 22.5 cm .

Step-by-step explanation:

We can see that , the given different models of the same triangular-shaped garden are similar.

For the first model 1 cm = 3.75 m

whereas for the second model 1 cm = 2.5 m

Now , the constant rate of proportion for this (k) = [tex]\dfrac{3.75}{2.5}=\dfrac{375}{250}=1.5[/tex]

Now , if height of the model on the left is 15 cm , then the height of the model on right = 15 x k

= 15 x 1.5

= 22.5 cm

Hence, the height of the model on the right is 22.5 cm .

Answers

Answer:

F(y^2) = 1/ (y^2-3)

Step-by-step explanation:

F(x) = 1/ (x-3)

Replace x with y^2

F(y^2) = 1/ (y^2-3)

Answer: f(y^2) = 1/((1/(x-3))^2-3)

Step-by-step explanation:

To start to understand this equation realize y = f(x) but f(x) gives a little bit more information specifically to define x as whatever is in the parenthesis of f(_).

For example f(x) = x/2

so lets say x = 2

so "f(2) = 2/2" or "y = 1 when x = 2"

In this equation y or f(x) = 1/(x-3)

so to get f(y^2) = 1/(x-3)

square the value of y and plug it into 1/(x-3) as the value of x

f(y^2) = 1/(y^2-3)

if tan theta=3/4, find sin theta

Answers

Answer:

sin(theta)=3/5

Step-by-step explanation:

tan(theta)=3/4

sec^2(theta)=1+tan^2(theta)=1+(3/4)^2=1+9/16=(16+9)/16=25/16

sec(theta)=square root of(25/16)=5/4

sec(theta)=1/cos(theta)=5/4

cos(theta)=4/5

sin^2(theta)=1-cos^2(theta)=1–16/25=(25–16)/25=9/25

sin(theta)=3/5

So

sec(theta)=5/4

sin(theta)=3/5

Which linear equation includes the points
(6,0) and
(0, – 4)?

Answers

Answer:

y= (2/3)x - 4

Step-by-step explanation:

To answer this you'll want to use the slope intercept form of a line:

y= mx + b

So to solve essentially you just have to find the values for m and b

- m represents the slope of the line

- b is the y-intercept (the point where the line crosses the y-axis)

You can figure that b = -4 because the line will cross the y-axis when x = 0, and you are given the point on the line (0,-4), where x is equal to 0.

Now to find the slope of the line, since you are given two points on the line you will want to use the slope equation:

slope = [tex]\frac{y1-y2}{x1-x2}[/tex]

So you can assign each of the two points a number (1 or 2) where its values are equal to (x1, y1) or (x2, y2). It does not matter which point gets which number.

In this example:

We will assign the point (6,0) to be (x1, y1),

and we will assign the point (0, -4) to be (x2, y2)

So we end up with the following:

m= [tex]\frac{0- (-4)}{6-0}[/tex]

m=  [tex]\frac{0+4}{6}[/tex]

m=  [tex]\frac{4}{6}[/tex]

Simplify the fraction:

m = [tex]\frac{2}{3}[/tex]

From there you just substitute in for m and b into the slope intercept equation

Now as we can see from the first ⇒ second step the process as to simplify the expression 5 + [ 2 * 2 + 5 ] further, was by adding 2 and 5. Of course by PEDMAS, it would be that multiplication takes place before that of addition, so that it should have been that 2 was multiplied by 2 first!
