Rachel ran 3 miles when she was training for a race. How many feet did she run?

Answers

Answer:

15,840 i did this in test and got 100%

Step-by-step explanation:

The total feet ran by Rachel is given by the equation A = 15,840 feet

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the total miles ran by Rachel be A = 3 miles

Now , the value of 1 mile = 5,280 feet

Substituting the values in the equation , we get

The distance of 3 miles in feet = 3 x value of 1 mile

On simplifying the equation , we get

The distance of 3 miles in feet = 3 x 5,280

The distance of 3 miles in feet = 15,840 feet

Therefore , the distance ran by Rachel A = 15,840 feet

Hence , the equation is A = 15,840 feet

Answer:

I think it C

Step-by-step explanation:

Let's solve your equation step-by-step.

(k−4)2=9

Step 1: Simplify both sides of the equation.

k2−8k+16=9

Step 2: Subtract 9 from both sides.

k2−8k+16−9=9−9

k2−8k+7=0

Step 3: Factor left side of equation.

(k−1)(k−7)=0

Step 4: Set factors equal to 0.

k−1=0 or k−7=0

k=1 or k=7

Answer:

k=1 or k=7

Hope this helps! :)

Square both sides:

K -4 = sqrt(9)

With the answer being a square root rewrite with a postive and negative value:

K-4 = sqrt(9)

And

K-4 = -sqrt(9)

Simplify each:

K-4 = 3

And

K-4 = -3

Solving for k in each one you get answer

You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?

Answers

Answer:

$17,276

Step-by-step explanation:

Given data

Time= 5 years

Principal= $14,000

Rate= 4.3%

We want to find the final amount

A=P(1+r)^t

Substitute

A= 14000(1+0.043)^5

A= 14000(1.043)^5

A= 14000*1.234

A=$17276

Hence the total amount is $17,276

How many quart are 8/1/4 gallons

Answers

Given:

Consider the given gallons are [tex]8\dfrac{1}{4}[/tex] gallons.

To find:

The number of quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

[tex]8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}[/tex]

Therefore, there are 33 quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

The sum of three numbers is 235. The second number
is 15 more than the first number, and the third number
is 8 times the first number. Find the second number.

Answers

Answer:

37

Step-by-step explanation:

x = 1st number

y = 2st number

z = 3rd number

x + y + z = 235

y = x + 15

z = 8x

x + x + 15 + 8x = 235

10x = 220

x = 22

y = 37

z = 176

The second number is 37.

Given that,

The sum of three numbers is 235. The second number  is 15 more than the first number, and the third number  is 8 times the first number.Here we assume the first number be x, second number be y, and third number be z.

Based on the above information, the calculation is as follows:

x + y + z = 235  

y = x + 15  

z = 8x

Now  

x + x + 15 + 8x = 235

10x = 220

x = 22

So,

y = 22 + 15

= 37

At a certain time of day, the sun shines on a large flagpole causing a shadow that is twice as long as the flagpole is tall what is the height of the flagpole to the nearest tenth of a foot?

350ft

Answers

Answer:

156.5

Step-by-step explanation:

The height of the flagpole to the nearest tenth of a foot is 156.5 ft.

Word Problems Using Pythagoras Theorem:

Word Problems involving the use of the Pythagoras theorem need careful understanding to discern the complexity of the variables given, the using the Pythagoras theorem to solve the eqaution.

The Pythagoras Theorem states that the sum of the squares of the opposite side and the adjacent side is equal to the hypotenuse square.

From the information;

The large flagpole height = adjacent = xThe shadow of the flagpole = opposite = 2xThe hypotenuse = 350 ft

Using the Pythagoras theorem, we have;

hyp² =  opp² + adj²

350² = (2x)² + x²

350² = 4x² + x²

122500 = 5x²

x² = 122500/5

x² = 24500

x = √24500

x = 156.5 ft

Therefore, we can conclude that the height of the flagpole is approximately 156.5 ft.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

A support wire is attached to the top of an antenna. The support wire connects to the ground 15 feet from the bottom of the antenna.

Let x be the height of the antenna.

We can find the length of the antenna using the trigonometric ratios:

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying tan ratio in the right angle triangle:

tan70 = x/15

x =15tan70

x = 41.212 feet  ≈ 41.23 feet

Thus, the height of the antenna is 41.23 feet if the support wire is attached to the top of the antenna.
