Ana can swim at a rate of
of mile in hour.
How many minutes would it take her to swim one mile at this rate? Round your answer to the nearest minute.

Answer:

let x be the number of cats and y be the number of dogs:

x + y = 40

4x + 4y = 160

If you divide both sides of the second equation by 4, you will be left with:

x + y = 40

Then, subtract both equations:

x + y =40

- (x + y = 40)

0 = 0

Since you have a number = a number, there are infinite solutions.

Answer:

x = 51

Step-by-step explanation:

x = 180 - (2x - 8) - (180 - 153)

x = 180 - 2x + 8 - 27

3x = 180 - 27

3x = 153

x = 51

Answer:

80.5

Step-by-step explanation:

2x-8 + x =153

Step-by-step explanation:

Answer:

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Step-by-step explanation:

Given

Given that the function f(x) and g(x) are inverse functions.

[tex]f\left(x\right)\:=\:\frac{1}{3}x\:+\:5[/tex]

[tex]g(x) = 3x - 15[/tex]

To determine

Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Determining the inverse function of f(x)

A function g is the inverse function of f if for y = f(x), x = g(y)

[tex]y=\frac{1}{3}x+5[/tex]

Replace x with y

[tex]x=\frac{1}{3}y+5[/tex]

Solve for y

[tex]y=3x-15[/tex]

Therefore,

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Part A: S^2= 3V/H

Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]

Part C: s=√3* 2,433,400 /138=230 metres

Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.  

Part E: S = √3*2,115,072/ 136 =216 metres

Part F: The length of Khafre's pyramid is about 215.5  My calculation was a little off, but not by much.

Part G: 14 meters longer

Step-by-step explanation:

Part A:

I am going to solve:

So,

V=1/3 [tex]HS^{2}[/tex]

Then, multiply both sides by 3:

V x 3= 1/3 [tex]HS^{2}[/tex] x 3

So,

3V=[tex]HS^{2}[/tex]

Then, we divide by H:

[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]

So,

[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]

Then switch sides:

[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]

I hope this helps!

Answer:

Answer:

They intersect

Step-by-step explanation:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.

Here we have two functions:

1) y = 4x + 2

2) 8x + 2y = - 3

   2y = - 8x - 3

   // divide both sides by 2

   y = - 4x - 1,5  

- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

Answer:

4x, if that is an option

Answer:

AB ≈ 5.59 m

Step-by-step explanation:

The arc AB is calculated as

AB = circumference of circle × fraction of circle

      = 2πr × [tex]\frac{40}{360}[/tex] ( r is the radius )

      = 2π × 8 × [tex]\frac{1}{9}[/tex]

      = 16π ÷ 9 ≈ 5.59 m ( to the nearest hundredth )

Answer:

Step-by-step explanation: your goal is to keep x on one side and everything else on the other.

subtract 1 from both sides

4x = -48

divide 4 on both sides

x= -12

Answer:

Yes, it does mean multiplication.

Answer:

Step-by-step explanation:

-8 > 4 +2v ; subtract 4 from both sides

-8-4 > 4-4 +2v; calculate

-12 > 2v; divide both sides by 2

-6 > v

TO Know:

apply the same operation to both sides of inequality

if the operation is dividing or multiplying by a negative number change the direction of the inequality

Answer:

$100

Step-by-step explanation:

you have eight bowls so you divide 160 by 8 and you get 20 so each bowl is 20 so 5x20=100

Answer:

100

Step-by-step explanation:

First, calulate the cost of each bowl, so, 160/8=20

Next, calculate how much total it costs, so 20x5, which the answer is $100

18. 8 7/10

Step-by-step explanation:

10.

256/8=32

12. If 3/4 = 4 then 4/4=? to find how much 1/4 is, divide 3/4 (aka 4) by 3 to get

1 1/3. Then to find 4/4 multiply 1 1/3x4 to get 5 1/3

14.

4.80/6=0.8

16. If 2/3 = 1/3 then ?=3/3 to find how much 1/3 is, divide 2/3 (aka 1/3) by 2 to get 1/6. Then to find 3/3 multiply 1/6x3 to get 3/6 (simplifies to 1/2)

18. if 21 3/4 = 2 1/2 then ?=2/2 to find how much 1/2 is, divide 2 1/2 (aka 21 3/4) by 5 to get 4 7/20. Then to find 2/2 multiply 4 7/20x2 to get 8 14/20 (simplfies to 8 7/10)

Hope this helps have a blessed day :)

Answer:

Not simplified

Step-by-step explanation:

Because there is 2x and x where you add it up to get 3x

______________________________

- To simplify this, all you have to do is combine like terms. In this case you have 2 [tex](x)[/tex] variables. So you just add/subtract them.

So your answer is [tex]\bold{x+4}[/tex].

Answer:

C.9

Step-by-step explanation:

The simplified base for the function given is 9.

A function in math is a rule or expression that defines a relationship between one variable (the input or independent variable) and another variable (the output or dependent variable). A function assigns to each input exactly one output.

Given that, a function f(x) = 2(∛27)²ˣ, we need to find its simplest base,

So,

f(x) = 2(∛27)²ˣ

= 2(3)²ˣ [∵ 3³ = 27, ∴ ∛27 = 3]

= 2(3²)ˣ

= 2(9)ˣ

Hence, the simplified base for the function given is 9.

Step-by-step explanation:

So to find a relative frequency you add up everything. so 30 for the results all together then you take whatever it focuses on and turn it into a fraction.

For question F it would be 8/30 or .26%
