Answer 1

Hi there!

To find surface area, all you do is add up all of the areas if the faces.

41 × 32 = 1312
1312 × 2 = 2624

41 × 49 = 2009
2009 × 2 = 4018

32 × 49 = 1568
1568 × 2 = 3136

2624 + 4018 + 3136 = 9778

9778 ft squared would be the answer.

Hope this helps!

Answer 2

Hey there!

In this problem, we'll just be finding the surface area of a rectangular prism. In this example, a surface area is a sum of all the areas of each individual face. On this rectangular prism, we have 6 faces, and two of each kind. Our formula is:

SA = 2(lw + wh + lh)

Notice how it has a 2. That two is because those two variables just applies for one side, and there's two for each type of side. On this diagram, the rightmost side's area would be the width (32) times the height (49) and the product would be the area. Let's plug in our numbers:

SA = 2(41 * 32 + 32*49 + 41*49)

Multiply:

SA = 2( 1312 + 1568 + 2009) =

Add:

SA = 2(2880 + 2009)

SA = 2(4889)

SA = 9778 ft squared, or C.

Hope this helps!

Calculate the area of a circle with a diameter of 6cm

Answers

Formula for area of circle:
A=πr²
Here diameter, d= 6 cm
Radius, r= d/2 = 6/2 = 3 cm
Put values
A= 3.14 x 3²
A=3.14 x 9
A=28.26 cm²

Answer: 28.26 cm²

Hey there!

We'll do it in terms of Pi, as a variable, and in terms of pi as 3.14

We know that since the diameter is from one side to the other in a circle, dividing it by 2 will give you the radius - the distance to the middle. We plug in this radius to our area formula:

a = [tex] \pi (r^2)[/tex]
a = [tex] \pi (3^2)[/tex]
a = 9[tex] \pi [/tex]

If our area is 9 pi, we can multiply 9 by 3.14 to get an approximate value:

A = 3.14(9)
A = 28.26

how to unfoil quickly try not to use a lot of steps.

Answers

regroup; (x³+4x²)-(9x+36)
take out: x²(x+4)-9(x+4)
take out (x+4): (x+4)(x²-9)
factor again: (x+4)(x+3)(x-3)

Final answer:

To unfoil quickly, use the reverse foil method. Identify the first and last terms of each binomial, multiply them, and rewrite the middle term as the sum of the products. Example: (x + 2)(x - 3) = x^2 + 2x - 3x - 6.

Explanation:

To unfoil quickly, you can use a shortcut called the reverse foil method. Reverse foil allows you to quickly determine the original factors of a quadratic expression that has been expanded using the distributive property. Let's say we have the expression (x + 2)(x - 3) and we want to unfoil it. Start by identifying the first term of each binomial, which in this case is x from (x + 2) and x from (x - 3). Multiply these two terms together to get x^2. Then, identify the last term of each binomial, which is 2 from (x + 2) and -3 from (x - 3). Multiply these two terms together to get -6. Finally, rewrite the middle term of the expanded expression as the sum of the two products obtained: (x^2 + 2x - 3x - 6). In this way, you can unfoil the expression quickly and identify the original factors without having to expand it fully.

100 children attended a play on the trip 0.6 were girls. Which fraction represents the number of boys on the trip

Answers

Since 0.6 (or 60%) of the children were girls, 0.4 or 2/5 would be the answer for boys.

Hope this helped!

Final answer:

The number of boys who attended the play is 40. Expressing this as a fraction of the total children (100), we get 40/100, which simplifies to 2/5. So, the fraction representing the number of boys on the trip is 2/5.

Explanation:

The provided information suggests that 60% (or 0.6) of the children on the trip, which were 100, were girls. This means the percentage or portion of girls on the trip is 0.6*100 = 60 girls. Since we're looking for the number of boys, we have to subtract this figure from the total number of children.

So, 100 total children - 60 girls = 40 boys. To express this as a fraction of the total number of children, we get 40/100. This fraction, however, can be simplified to 2/5, which is the fraction that represents the number of boys on the trip.

Given: ABCD is a trapezoid,
AD = 10, BC = 8,
CK
- altitude
Area of ∆ACD = 30.
Find: Area of ABCD

Answers

To answer this you will draw a trapezoid and label the points A through D in order. See the picture I have attached. When you create triangle ACD, you have the base of the triangle as 10 and you know the total area. Using this information you can find the height. See the work in the picture. You will solve the equation to find the Height. When you know the height, then you can use the formula for area the trapezoid to find the area of this trapezoid. I have included the work for all the steps described.

Therefore, the area of trapezoid ABCD is 54 square units.

To find the area of trapezoid ABCD, we can use the properties of a trapezoid and the given information.

First, let's denote the unknown base of the trapezoid as BD = b. Since AD and BC are the other two bases, we have AD = 10 and BC = 8. The height of the trapezoid is the same as the altitude of triangle ACD, which is KC = h and is given to be such that the area of triangle ACD is 30.

The area of a triangle is given by the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \][/tex]

For triangle ACD, we have:

[tex]\[ 30 = \frac{1}{2} \times AD \times h \][/tex]

[tex]\[ 30 = \frac{1}{2} \times 10 \times h \][/tex]

[tex]\[ h = \frac{30 \times 2}{10} \][/tex]

[tex]\[ h = 6 \][/tex]

Now that we have the height of the trapezoid, we can calculate the area of the trapezoid using the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (\text{sum of parallel sides}) \times \text{height} \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times (AD + BC) \times h \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times (10 + 8) \times 6 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 18 \times 6 \][/tex]

[tex]\[ \text{Area} = 9 \times 6 \][/tex]

[tex]\[ \text{Area} = 54 \][/tex]

Suppose a small airplane has a wingspan of 15 feet. Find the wingspan of a model of the airplane, in inches, if the scale factor is 1 60 .

Answers

The answer is 3 inches

Solution:

we are given that

Airplane has a wingspan of 15 feet.

we have been asked to find the wingspan of a model of the airplane, in inches, if the scale factor is 1:60 .

It mean for each one unit of original wingspan we are supposed to have [tex]\frac{1}{60}th[/tex] times the wingspan of model airplane.

Here the original airplane has a wingspan of 15 feet. So the model airplane has a wingspan of [tex]\frac{1}{60}*15=\frac{1}{4} ft[/tex]

Since one fit=12 inches So we can say

[tex] \frac{1}{4} ft=\frac{12}{4} inches=3 inches.[/tex]

Hence the model airplane has a wingspan of 3 inches.

Adventure Play sells an mp3 player for $18.00 and charges $3.25 per song. King Music sells a player for $23.00 and charges $2.00 per song. For how many songs will the cost be the same?

Answers

System of equations. Start by writing the equation for each one.
For Adventure Play, 18 is the y-intercept (b) and the slope is 3.25 (m).
y = mx + b
y = 3.25x + 18
For King Music, 23 is the y-intercept and the slope is 2.
y = 2x +23
Since they both equal y, you can set them equal to each other and solve.
2x + 23 = 3.25x + 18
Get x on one side and a variable-free quantity on the other.
3.25x - 2x = 23 - 18
Simplify
1.25x = 5
Then divide both sides by 1.25 to get x by itself.
x = 5/1.25
x = 4
For four songs, the cost will be the same.

The total number of songs is 4 at which the total cost be the same and this can be determined by forming the linear equation in two variables.

Given :

Adventure Play sells an mp3 player for $18.00 and charges $3.25 per song.King Music sells a player for $23.00 and charges $2.00 per song.

Let the total number of songs be 'x' and the total cost be 'y'. Now, Adventure Play sells an mp3 player for $18.00 and charges $3.25 per song sp the total cost is given by:

y = 18 + 3.25x --- (1)

Also given that King Music sells a player for $23.00 and charges $2.00 per song so, the total cost is:

y = 23 + 2x --- (2)

Given the total cost will be the same, that is, equate equations (1) and (2).

23 + 2x = 18 + 3.25x

Simplify the above equation in order to determine the value of 'x'.

23 - 18 = 3.25x - 2x

5 = 1.25x

x = 4

So, the total number of songs is 4 at which the total cost be the same.

Which of the following is the inequality −18x + 2y ≥ −13 written in slope-intercept form?

Select one:
A. y ≥ - 6.5x - 9
B. y ≥ 7x - 10
C. y ≥ 9x − 6.5
D. y ≥ 10x - 7

Answers

Hey there! :)

We're simply just trying to convert "-18x + 2y ≥ -13" into slope-intercept form.

First, we need to know what slope-intercept form is.

Slope-intercept form is : y=mx+b , where m=slope and b=y-intercept.

In order to convert our given equation into slope-intercept form, we have to isolate "y."

We can do this by adding 18x to both sides.

2y ≥ 18x - 13

Then, divide both sides by 2.

2y ÷ 2 = (18x - 13) ÷ 2

Simplify.

y = 9x - 13/2

Convert -13/2 into a mixed fraction.

So, simply divide -13 by 2.

-13 ÷ 2 = -6.5

Plug in -6.5 into where -13/2 was.

y = 9x - 6.5

Therefore, your answer is C : y ≥ 9x - 6.5
