Answers

Answer:

h = 120

Step-by-step explanation:

The required, division of h=(500-260)divided by 2 is 120..

The division is a mathematical operation that involves distributing or sharing a quantity into equal parts. It is the inverse operation of multiplication. In division, a dividend is divided by a divisor to obtain a quotient.

h = (500 - 260) divided by 2

To solve this expression, we first perform the subtraction within the parentheses:

h = (240) / 2

Simplifying further:

h = 120

Therefore, the value of h is 120.

Answer: 6 2/3 ft

Explanation:

1. Turn the mixed number (26 2/3) into an improper fraction by multiplying 26 by 3 and then adding 2. (26x3=78)(78+2=80=80/3)

2. Now divide 80 by the number of pieces she’s cutting (4). (80÷4=20)

3. Now divide 20 by the denominator (3) to convert it back into a mixed number. (20÷3=6 2/3)

Solve the system of linear equations by elimination,
-y - 10 = 6x
5x +y = -10

Answers

Hey again!

The solution to the given system is (0, -10)

To solve using elimination, we have to add the equations together, and the "y"s will cancel out, and then solve the equations:

5x - 10 = 6x - 10

Now solve.

Add "10" to both sides:

5x = 6x

Subtract "5x" from both sides

0 = x

Now, we plug in the solved "x" value in an equation to solve for "y".

5(0) + y = -10

y = -10

We now know that the solution to the given system is (0, -10)

Hope this helps! Have an amazing day, and remember, you've got this!!

The solution to the given system of linear equations is (0, -10) which is determined by the elimination method.

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

The system of linear equations is given in the question:

-y - 10 = 6x    ....(i)

5x +y = -10    ....(ii)

To solve using elimination, we have to add the equations (i) and (ii) together, and the "y" will be eliminated, and then solve the equations:

⇒ 5x - 10 = 6x - 10

Add "10" to both sides of the above equation

⇒ 5x = 6x

Subtract "5x" from both sides

⇒ 0 = x

⇒  x = 0

Now, substitute the value of x = 0 in equation (ii) to solve for "y".

⇒ 5(0) + y = -10

⇒ y = -10

Therefore, the solution to the given system of linear equations is (0, -10).

What is the missing side length in this right triangle?

Answers

Answer:

15

Step-by-step explanation:

It's a right angle triangle so we can use the pythogorean theorem to solve for Hypotenuse

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

So if we apply this formula,

[tex] {9}^{2} + {12}^{2} = {c}^{2} [/tex]

[tex]81 + 144 = {c}^{2} [/tex]

[tex]225 = {c}^{2} [/tex]

[tex]c = \sqrt{225} [/tex]

[tex]c = 15[/tex]

Hope this helps :)

Okay first off you need to use the Pythagorean Theorem Equation:

a^2 + b^2 = c^2

Now since we know a = 9, and b = 12 we can plug those in :)

9^2 + 12^2 = c^2

Remember 9^2 = 81, 12^2 = 144

81 + 144 = c^2

Now add those together m

225 = c^2

Now we need to square root both sides to get rid of the power of 2

square root(225) = square root(c^2)

So the answer is ——> c = 15

A rope is tied to a tent for support as shown. Rope Support 14 TL sin What is the length of the rope?​

Answers

Answer: 10ft

Step-by-step explanation:

The pole and the distance between the rope and pole make this appear as though it is a right angled triangle which means that one should be able to calculate the length of the rope by using the Pythagorean rule where:

c² = a² + b²

a = height of right angle triangle

b = length of right angle triangle

c = hypotenuse (length of rope)

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10 ft

Length of rope = 10ft

You are in the buy and sell business. find out the wholesale price of an item (e.g. t-shirt, soap,toy) suppose you buy 24 pieces of that item at wholesale price. atleast at what price should you tell each item to have a 25% profit? how much will be your total profit in pesos from these items?

With explanation please!!

Answers

The wholesale price isn't given, suppose the wholesale price is $5

Answer:

$6.25 ; 1441.8 pesos

Step-by-step explanation:

Number of items purchased = 24

Wholesale price of item = x

To obtain a 25% profit, the sales price would be :

Wholesale price = wholesale price + 25% of wholesale price

(x = x + 0.25x) per unit

For 24 items :

24x + 0.25 * 24x

Unit wholesale price = 5

24(5) + 0.25*24(5)

= $150

Hence, sale price per unit will be :

$150 / 24

= $6.25

Total profit in pesos :

1 dollar = 48.06 pesos

Total profit = $150 - 24(5) = $150 - $120 = $30

$30 = (30 * 48.06) = 1441.8 pesos

When glaciers were melting during the last ice age, the moving water dug away at the bedrock of this area. The result is the magnificent Quechee Gorge with the Ottauquechee River running through it. Walking around the gorge provides visitors with exercise options and different perspectives.First of all, walking the hiking trails provides tourists with the opportunity to exercise. Hikers may choose to walk along the pathways at the top of the gorge, which is a mile long. They can enjoy the fall colors and the fresh scent of pine trees. Adventurous individuals may choose to walk to the bottom of the gorge. The gorge is 165 feet deep, but the gravel hiking trail takes visitors safely to the bottom. There, hikers can take a break and remove their shoes. They can wade in the shallow waters or sit on a rock to rest. Then they can climb back to the top of the gorge.Walking around the Quechee Gorge provides options. There are so many things to see! The lengths of the trails are listed, so hikers can decide how far they would like to walk. Visitors can walk along the top of the bridge overlooking the gorge. The bridge has a separate section for pedestrians that is separated from the roadway by a safety fence. Other hikers can walk to the dam and waterfall at the head of the gorge. If tourists get tired, they can rest at the Quechee Gorge Visitor Center or enjoy a meal in the picnic area beside the gorge. Visitors get to choose their adventure.Finally, the Quechee Gorge is a photographer's dream because there are so many different perspectives to enjoy. At the dam, photographers can capture the smooth line of water falling over the dam into the turbulent waterfalls below. The bridge offers a magnificent view of the length of the gorge. Some photographers may wish to capture the steel curves of the bridge itself. Hikers can take pictures from different spots along the trail, including a picture of the same bridge from the bottom of the gorge. The bumpy rocks at the bottom of the gorge contrast with the smooth, rushing water of the river. With such a wealth of perspectives, even beginning photographers will produce phenomenal pictures.Indeed, the perspectives, options, and physical exercise available at Quechee Gorge make this natural wonder a mandatory stop for walkers of all ages.Which of the following sentences supports the author's point of view?A.
