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,

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

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 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;

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.

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

Answer:

Step-by-step explanation:

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

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.

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

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
