Answer:

Step-by-step explanation:

Ooh I love these type of problems

Okay, here we go :

f = Fred and n = Nathan

  f = 4n

  f = n + 27

Above are the two equations (the words translated into algebra)

Now you can solve using substitution (any method works, but substitution is easiest for this problem)

4n = n + 27

3n = 27

n = 9

Since n = 9 substitute n into either equation

f = 4 * 9

f = 36

Fred is 36 and Nathan is 9

Answer:

Since they're asking you to find the missing sides "y" and "x" here's what you need to do....

Step-by-step explanation:

1) This is the 45-45-90 Triangle.

2) y = 20 becasue this is an isocelese triangle - meaning a triangle that has 2 sides of equal lengths!

3) in order to find x (which is the hyptoneus) you have to do

       [tex]\sqrt{2}[/tex] * leg (use on of the legs)

    =  [tex]20\sqrt{2}[/tex]

also I think 45 degrees is there just to throw you off. And I'm pretty positive this is the correct answer, and i'm 100% sure that y = 20 is correct!

Answer:

10 full servings and [tex]\frac{1}{4}[/tex] cups leftover

Step-by-step explanation:

Our container has a total of 20 and a half cups. And each full serving is 2 cups.

So, we divide [tex]\frac{20\frac{1}{2} }{2}[/tex].

To do this manually, we convert the numerator into an improper fraction: [tex]\frac{\frac{41}{2} }{2}[/tex].

Now, we multiply the denominators: [tex]\frac{41}{4}[/tex].

This will give us [tex]10\frac{1}{4}[/tex] servings. So we only have 10 full servings.

There are [tex]\frac{1}{4}[/tex] cups leftover.

Answer:

y = (10 * 0.2) ^ x

Y = (2)^x

Y =  2^x + 10

6.5 hours

Step-by-step explanation:

Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.

Answer:

y-10=5(x+2)

Step-by-step explanation:

y-y1=m(x-x1)

y-10=5(x-(-2))

y-10=5(x+2)

Answer:

Step-by-step explanation:

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)

m = 5

x₁ = -2

y₁ = 10

Therefore the equation:

Answer:14.4

Step-by-step explanation:

I’m pretty sure it’d be y = -x - 2

lmk if it’s wrong.

Let me break this up.

Note: (f o g)(2) = f(g(2)).

Note: g(2) = (2, 2) means when x is 2 y is 2.

In other words, g(2) is 2.

We know that f(g(2)) = f(2).

You can see that f(2) = -3. This is given in the point (2, -3).

So, f(g(2)) = -3.

Done.

Answer:

3a² + 3b² - 20ab

Step-by-step explanation:

Sum of 12ab-10b²-18a² and 9ab+12b²+14a²

12ab - 10b² - 18a² + 9ab + 12b² + 14a²

= 14a² - 18a² + 12b² - 10b² + 12ab + 9ab

= -4a² + 2b² + 21ab

Sum of ab + 2b² and 3b²- a²

= ab + 2b² + 3b²- a²

= -a² + 2b² + 3b² + ab

= -a² + 5b² + ab

Subtract

-a² + 5b² + ab - (-4a² + 2b² + 21ab

)

= -a² + 5b² + ab + 4a² - 2b² - 21ab

= 3a² + 3b² - 20ab

4*6=24     answer:6

any other number would be less or more

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

4 x 6 is 24 and 4 x 7 is 28. 26 is between 24 and 28, so got to 24 since that is less than 26. 4 x 6 gets you 24, so 6 is your answer.

Hope it helps!

Answer:

The answer is 131 people

Step-by-step explanation:

I'm not too sure about equations bc its been a min since I've done them but maybeeeee it's 26x - (1,575) = 5,000 something like that LOL

All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.

Hopefully that helped lol

Answer:

52

Step-by-step explanation:

if 80 anps has 50 resistance then

52 has 22

80-30=50

52-30=22

Step-by-step explanation:

step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)

step 2. 15x + 15 = 180 (like terms)

step 3. 15x = 165 (subtract 15 from each side)

step 4. x = 11. (divide both sides by 15)

Answer:

Step-by-step explanation:

-x*3x*2x=6x^3

-6x^3<900

-(cube root both sides)

-6x<9.654893846

-divide by 6

-x=1.609148974

And since 1.609148974 is less than 5, that means that X<5 is correct and hence proved

For given cuboid, x < 5

"It is a three-dimensional geometric structure that has six rectangular faces, twelve edges and eight vertices."

V = l × w × h

where, l: length of the cuboid

w: width of the cuboid

h: height of the cuboid

For given example,

We have been given the total volume of the cuboid is less than 900 cm^3

⇒ V < 900 cm³

the length of the cuboid (l) = 3x

the width of the cuboid (w) = 2x

the height of the cuboid (h) = x

Using the formula of the volume of the cuboid,

⇒ V < 900

⇒ l × w × h < 900

⇒ (3x) × (2x) × (x) < 900

⇒ 6x³ < 900

⇒ x³ < 150

⇒ x < 5.3

⇒ x < 5

Therefore, for given cuboid, x < 5

Step-by-step explanation:

One way to compute a 20% discount is to multiply the price by 0.20. The price of a pair of sneakers is $84.50. Calculate the discount.

Given :

Height of the decorative pyramid = 15 inches

We know that :

[tex]\color{hotpink}\tt \: volume \: of \: a \: triangular \: pyramid\color{plum} \tt \: = \frac{1}{3}Bh [/tex]
