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
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.

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

Find the system determinant of the given matrix.

Answers
The determinant of 2 x 2 matrix can be calculated as follows:
1) Multiply the main diagonal elements.
The main diagonal elements are 2 and -9. Multiplying them we get -18
2) Multiply the remaining two elements (Non diagonal elements)
The other two elements are 3 and 4. Multiplying them we get 12.
3) Subtract the product of non diagonal elements from the product of diagonal elements, this will give the determinant of the matrix.
So, determinant will be = -18 - 12 = -30
In one step, this can be done directly as:
Determinant = 2(-9) - 3(4) = - 30
So, option A gives the correct answer

100 children attended a play on the trip 0.6 were girls. Which fraction represents the number of boys on the trip
Answers
Hope this helped!
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.

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
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

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