Answer:

The actual length of the helicopter is 23 feet.

Step-by-step explanation:

Given:

On a scale drawing, a helicopter is 2.3 feet long.

The scale on the drawing shows a ratio of 1 foot to 10 feet.

Now, to find the actual length of the helicopter.

Let the actual length of helicopter be [tex]x[/tex].

On scale drawing length of helicopter = 2.3 feet.

The scale on the drawing shows a ratio = 1:10.

Now, as ratios are given so by setting proportion we solve it:

[tex]\frac{2.3}{x} =\frac{1}{10}[/tex]

By cross multiplying we get:

⇒ [tex]2.3\times 10=x[/tex]

⇒ [tex]23=x[/tex]

⇒ [tex]x=23\ feet.[/tex]

Therefore, the actual length of the helicopter is 23 feet.

The amount given to them is GHS300.00

Step-by-step explanation:

A man gave an amount of money to his three sons Yao, Esi and Ampa in the ratio of  their years

We need to find the amount given to them

Let us use the ratio method to solve the problem

∵ Yao is 15 years old

∵ Esi is 10 years old

∵ Ampa is 5 years old

∴ The ratio between them is

→  Yao    :    Esi    :    Ampa

→  15       :    10     :    5

Simplify the terms of the ratio by divide each term by 5

∴ The ratio between their ages in the simplest form is

→  Yao    :    Esi    :    Ampa

→  3         :    2      :    1

∵ Esi had GHS100.00

→  Yao    :    Esi    :    Ampa    :   Total

→  3         :    2      :    1             :   6 ( 3 + 2 + 1 = 6)

→             :  100     :                  :    x

Use the cross multiplication to find x

∵ 2(x) = 100(6)

∴ 2x = 600

- Divide both sides by 2

∴ x = 300

∵ x represents the total money given to them

∴ The amount given to them is GHS300.00

The amount given to them is GHS300.00

Step-by-step explanation:

The given is:

We need to find who runs fastest

To solve the problem we must to find the unit rate of each one in feet per second

∵ Jake runs 334 feet and 26 seconds

- To find the unite rate divide 334 feet by 26 seconds

∴ Jake's rate = 334 ÷ 26 = 12.85 ft./s

∵ Katie runs 1 mile in 596 seconds

- Change the mile to feet

∵ 1 mile = 5280 feet

∴ Katie runs 5280 feet in 596 seconds

- To find the unite rate divide 5280 feet by 596 seconds

∴ Katie's rate = 5280 ÷ 596 = 8.86 ft./s

∵ Stephanie runs 580 feet in one minute

- Change the minute to seconds

∵ 1 minute = 60 second

∴ Stephanie runs 580 feet in 60 seconds

- To find the unite rate divide 580 feet by 60 seconds

∴ Stephanie's rate = 580 ÷ 60 = 9.67 ft./s

∵ Emily's rate is 10 ft./s

∵ Jake's rate is 12.85 ft./s

∵ Katie's rate is 8.86 ft./s

∵ Stephanie's rate is 9.67 ft./s

- The fastest one who has the greatest rate

∵ Jake's rate is the greatest

Answer:

you can make 14 muffins

Step-by-step explanation:

To get this answer you first need to know that 1 cup makes 8 muffins. Next know that there's 1 3/4 cups of flour. Because you know that 1 cup makes 8 muffins you need to figure out how many muffins 3/4 a cup of flour can make. To do this you divide 8 by 4. Hence 8 divided by 4 is 2. So know you know that for every 1/4 cup you can make 2 muffins. Now since there's 3/4 cup of flour you then multiply 2 by 3 which is 6. Now you have to add 1 cup ( 8 muffins) to 3/4 cup ( 6 muffins ) of flour which then equals 14. You then get the answer , 1 3/4 cups of flour can make 14 muffins. Hope this helped ;)

Answer:22%

Step-by-step explanation:

You paid approximately 27.12% gratuity on a $59 bill by leaving a $16 tip on a $75 payment.

To find out the percentage gratuity paid, you can first calculate the gratuity amount by subtracting the bill amount from the total paid:

Gratuity = Total paid - Bill amount

Gratuity = $75 - $59

Gratuity = $16

Now, to find the percentage gratuity, divide the gratuity amount by the bill amount and then multiply by 100:

Percentage Gratuity = (Gratuity / Bill amount) * 100

Percentage Gratuity = ($16 / $59) * 100

Percentage Gratuity ≈ 27.12%

So, you paid approximately a 27.12% gratuity.

Answer: 10.0

Step-by-step explanation: In this problem, we are asked to round 10.034 to the nearest tenth. It's important to understand that the tenths place is 1 place to the right of the decimal point. So the digit in the rounding place is 0.

Next, look at the digit to the right of the rounding place which in this case is 3. Since the digit to the right of the rounding place, 3, is less than 5, we round down.

This means that the digit in the rounding place, 0, stays the same and we change all digits to the right of the rounding place to 0.

So 10.034 rounded to the nearest tenth is 10.000 or just 10.0 since we can drop zeroes at the end of a decimal.

Answer:

one number is 90 and the other one 9

Step-by-step explanation:

Let's refer to the larger number as "x", and the smaller as "y", so we can create equations with those unknowns and solve them algebraically.

Now let's write the first phrase we are given in mathematical form:

"One number is 10 times as large as another one"

Remember that our larger number is "x", so the first equation out of this phrase is:

x = 10 * y

Now for the second phrase:

"Their difference is 81"

Here we need to make the difference setting the larger number first (x), minus the smaller number (y), so as to get a positive difference of 81 units:

x - y =81

now we solve this system by substituting "x" in the second equation with "10 * y" according to what our first equation states:

10 y - y = 81

9 y = 81

y = 81/9

y = 9

and therefore now that we know the value of number y (9) we can go back to the first equation to find what number "x" is:

x = 10 * (9)

x = 90

Finally: x = 90, and y = 9

The amount invested at 8% is $11,908 and the amount invested at 5% is $11,895

Step-by-step explanation:

Let

x ----> the amount invested at 8%

(23,803-x) ----> the amount invested at 5%

Remember that

[tex]8\%=8\100=0.08[/tex]

[tex]5\%=5\100=0.05[/tex]

we know that

The interest earned  from the amount invested at 8% is equal to the interest earned from the amount invested at 5% plus $357.89

so

The linear equation that represent this situation is

[tex]0.08x=0.05(23,803-x)+357.89[/tex]

solve for x

Apply distributive property right side

[tex]0.08x=1,190.15-0.05x+357.89[/tex]

Group terms

[tex]0.08x+0.05x=1,190.15+357.89[/tex]

Combine like terns

[tex]0.13x=1,548.04[/tex]

[tex]x=\$11,908[/tex]

[tex]\$23,803-x=\$23,803-\$11,908=\$11,895[/tex]

therefore

The amount invested at 8% is $11,908 and the amount invested at 5% is $11,895

Answer:($7.76/4)x 13

Step-by-step explanation: There is no way to start from the price of 4 glue sticks. So, you have to find the unit rate. The unit rate is the cost of 1 of the items. For example, if 8 apples was $5.65, you have to find out what 1 apple cost so you can buy as many apples you want, not just 8. After finding the unit rate, multiply the unit rate by 13. Back to the apple example, if I did not want 8 apples but 15, and I want to know what the price is before I go up to the counter to buy it, I would multiply the unit rate by how much I want.

Also, the answer to ($7.76/4)x 13 is $25.22. The unit rate was $1.94.

So first we have to know what (fog)(x) means. Whenever we have the notation (fog)(x) or (gof)(x) or whatever variables (hof)(c) it means that we put the function closest to the x in the other function.

Basically for (fog)(x) this means put g(x) in f(x)

For (hof)(c) this means put f(c) in h(c)

For (gof)(x) this means put f(x) in g(x)

So now we can proceed with the problem.

f(x) = x^2 - 2 (I assume you wrote x squared) and g(x) = x - 3. Find (fog)(x)

So we are going to put g(x) in f(x). So wherever there is an x in f(x) we are gonna replace that with x -3:

f(g(x)) = (x-3)^2 - 2

If we want we can foil this out:

(x-3)(x-3) - 2

x^2 - 6x + 9 -2

or x^2 - 6x + 7

So: (fog)(x) = x^2 - 6x + 7

The rate at which the area of the triangle changes when the height is 22 cm and the base is 10 cm is 14 cm²/min.

Using the formula for a triangle's area, A = (1/2) × base × height, we can determine rate of the triangle's area changes.

We can describe the rate of change of the base as db/dt = -1 cm/min (negative because it is shrinking) given that the base is shrinking at a rate of 1 cm/min.

The height is increasing at a rate of 5 cm/min, so the rate of change of the height can be expressed as dh/dt = 5 cm/min.

We must determine dA/dt for h = 22 cm and b = 10 cm in order to determine the rate at which the triangle's area changes at these two points.

We can start by differentiating the area formula with respect to time (t):

dA/dt = (1/2) × (db/dt × h + b × dh/dt)

Substituting the given values:

dA/dt = (1/2) × (-1 cm/min × 22 cm + 10 cm × 5 cm/min)

Simplifying:

dA/dt = (1/2) × (-22 cm/min + 50 cm/min)

= (1/2) × 28 cm/min

= 14 cm/min

Therefore, the rate at which the area of the triangle changes when the height is 22 cm and the base is 10 cm is 14 cm/min.

The rate at which the area of the triangle changes is 2 cm²/min. This is found by applying the chain rule of differentiation to the triangle area formula, substituting the given values and rates, and simplifying.

The subject of this question is rate of change in context of the Triangle Area Formula: 1/2 * base * height. Given that the base is shrinking at a rate of 1cm per minute (1 cm/min) and the height is increasing at a rate of 5 cm/min, we can express this rate of change in the formula. A negative sign is used for the base because the base length is decreasing.

To find the rate of change in the area, use the chain rule of differentiation, leading to the formula (-1/2 * height * db/dt) + (1/2 * base * dh/dt). When the height is 22 cm and the base is 10 cm, substituting these values along with the rates at which the base and height are changing, the formula becomes (-1/2 * 22cm * 1 cm/min) + (1/2 * 10cm * 5 cm/min). Simplify to find that the area of the triangle is changing at 2 cm²/min.
