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.

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.

Answer:

The base area , radius, and diameter can be determined when given the volume and height of a cone. Substitute the values for the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable. To find the diameter, double the radius.

Step-by-step explanation:

The formula for the cone is  [tex]\frac{1}{3} \pi r^2 h[/tex]. The cone is a  three-dimensional geometric object with a circular base that tapers to a point called the vertex from a flat base.

It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.

The volume of a cone is;

[tex]\rm V = \frac{1}{3} \pi r^2 h[/tex]

Where

h is the height of the cone

r is the radius

V is the volume

Hence the formula for the cone is [tex]\frac{1}{3} \pi r^2 h[/tex]

Answer:

3

Step-by-step explanation:

I know I'm late by 4 years but the answer is 3. This is because if you divide 12 by the 2 coins you'll get 6. You then need to divide it in half again because it's asking for both coins not only one. This gets you the answer of 3. I'm only writing this because other people may need help, 4 years later-

Answer:number c + 6

Step-by-step explanation:

You're adding 6 to the number c

We are given a two-way table that represents the frequency of three types of music.

Hence, the relative frequency table is given by:

                         Female             Male                Total

Country               145/1015         106/1015            251/1015

Rap                     158/1015         240/1015           398/1015

Rock                    214/1015          152/1015            366/1015  

Total                    517/1015           498/1015           1015/1015

                            Female             Male                Total

Country              0.143                 0.104                0.247

Rap                     0.155                0.237                0.392

Rock                    0.211                 0.150                 0.361

Total                   0.509                 0.491                   1

Hence, clearly we could see that the relative frequency of the music country is much low as compared to that of Rock and rap.

Hence, there is a much difference between the bar of Country as compared to Rock and rap.

and there is a low difference between the bar of rock and rap.

To calculate the available space for food in the refrigerator, multiply its external dimensions (3 ft wide, 2.5 ft deep, and 6 ft high) to get the total volume of 45 cubic feet. Subtracting the 20 cubic feet taken up by the walls and other parts, we find there are 25 cubic feet left for food storage.

The question asks us to calculate the available space for food inside a refrigerator given its external dimensions and the space taken up by the walls and other parts. The refrigerator is 3 ft wide, 2.5 ft deep, and 6 ft high. The total internal volume before accounting for walls and other parts is calculated by multiplying these dimensions:

Volume = Width × Depth × Height = 3 ft × 2.5 ft × 6 ft = 45 cubic feet.

Given that the walls and parts take up 20 cubic feet, we subtract this from the total internal volume to calculate the space left for food:

Available space for food = Total internal volume - Space taken by walls and parts = 45 cubic feet - 20 cubic feet = 25 cubic feet.

Therefore, the refrigerator has 25 cubic feet of space available for storing food.

Answer: 42

Step-by-step explanation:

Call the first number in the sequence xx.

Hint #22 / 8

The next even number in the sequence is x + 2x+2

Hint #33 / 8

The sum of the 66 consecutive even numbers is:

x+ (x + 2)+ (x + 4)+ (x + 6)+ (x + 8)+ (x + 10) = 270x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=270

Hint #44 / 8

6x + 30= 2706x+30=270

Hint #55 / 8

6x = 2406x=240

Hint #66 / 8

x = 40x=40

Hint #77 / 8

Since xx is the first number, x + 2x+2 is the second even number.

Hint #88 / 8

Thus, the second number in the sequence is 4242.
