What is a triangle?

A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.

For the given situation,

The tile is in the shape of right triangle.

The sides of triangle are 10 in, 8 in, 6 in.

Here, Base of the triangle,b = 6 in

Height of the triangle,h = 8 in

The formula of area of triangle is

[tex]Area = \frac{1}{2}(base) (height)[/tex]

⇒ [tex]A=\frac{1}{2}(6)(8)[/tex]

⇒ [tex]A=24[/tex]

Hence we can conclude that the area of the tile is 24 square in.

Which is the most accurate way to estimate 26% of 91?

A: 3/4 x 92
B: 1/4 x 92
C: 1/3 x 90
D: 1/2 x 90

Answers

Answer:

B

Step-by-step explanation:

26% is close to 25%, which is equal to 1/4th.

You're adding to the number and removing from the percentage so it balances it out.

The estimation of 26% of 91 is  1/4 x 92.

The correct option is (B).

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

26% of 91

Now solving the above Quantity

= 26 /100 x 91

Now, We take 1 from 26 make it 25 and add that 1 to 91 make 92.

Then, 25 / 100 x 92

= 1/4 x 92

Hence, the estimation is 1/4 x 952.

=_/(12)^2

=12 Ans

Answer:

12

Step-by-step explanation:

to find the altitude which is e,using geometric mean, you need to :

multiply the two values that are given, which is the value in between JM and the value in between mL

so 6*24 =144

then the square root of the result, which is 144, is the altitude which is e.

so 144 = 12

A cylindrical tank has a height of 10 feet and a radius of 4 feet. Carla fills the tank with water at a rate of 8 cubic feet per minute. At this rate, how many minutes will it take Carla to completely fill the tank without it overflowing? Round your answer to the nearest minute.

Answers

Area = 10(pi)(16) = 160pi cubic feet
160pi = 502.56
502.56/8 = 63 minutes

The time it will take for Jane to completely fill the tank without overflowing would be 62.8 minutes.

Used the concept of the volume of the cylinder:

The volume of the cylinder can be determined using the formula,

[tex]V = \pi r^2h[/tex]

Given:

A cylindrical tank has a height of 10 feet.

The radius of the cylindrical tank is 4 feet.

Jane fills the tank with water at a rate of 8 cubic feet per minute.

Since, the volume of the cylinder:

[tex]V = \pi r^2h[/tex]

Substituting the values, we have;

[tex]V = 3.14 \times 4^2 \times 10[/tex]

[tex]V = 502.4 \tex{ feet^3 }[/tex]

Thus, the volume of the cylinder is 502.4 cubic feet.

Time taken:

The time taken can be determined using the formula,

[tex]\text{Time} = \dfrac{\text{Volume}}{\text{Rate of filling}}[/tex]

Substituting the values, we have;

[tex]\text{Time} = \dfrac{\text{502.4}}{\text{8}}[/tex]

[tex]\text{Time} = 62.8[/tex]

Thus, Jane takes 62.8 minutes to completely fill the tank without overflowing it.

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake

Answers

Answer:

54 inches

Step-by-step explanation:

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake

Step 1

We would be converting the length of the Royal's pet snake to inches

1 foot = 12 inches

8 feet = x

Cross Multiply

x = 8 × 12 inches

x = 96 inches

Step 2

How many inches longer is Royal's snake?

This is calculated by subtracting the length of the Royal's pet snake from the least length

= 96 inches - 42 inches

= 54 inches

Therefore, the Royal's snake is 54 inches longer

The factorys CFO estimates that the existing press has 6 years of useful life remaining. The purchase price for the new press is $280000. The installation of the new press would cost an additional $20000, and this installation cost would be added to the depreciable base.
