Stephanie has a fish tank with 8 adult fish and 36 baby fish. What is the ratio of adult fish to baby fish in the tank?

Answer:

7 hours

Step-by-step explanation:

Step one:

given data

let the total charges be y and the number of hours be x

Company A charges

$60 reservation fee plus another $15 per hour.

so

y=60+15x----------1

Company B charges

$25 reservation fee plus another $20 per hour

y=25+20x------------2

Step two:

equate the 2 expressions above we have

60+15x=25+20x

collect like terms

60-25=20x-15x

35=5x

divide both sides by 5

x= 35/5

x= 7 hours

Answer:

Geography? You mean middle school math? But anyways, the measure of angle 6 is 143 degrees.

Step-by-step explanation:

So, all the angles that measure 37 degrees are 1, 4, 5, and 8. First, you know that 37 + x = 180. Now, do 180 - 37. You should get 143, you are welcome.

Answer:

its 6

Step-by-step explanation:

6-4=2

2*3=6

hope it helps

Hey there!

In order to answer this question, you have to do PEMDAS

• Parentheses

• Exponents

• Multiplication

• Division

• Addition

• Subtraction

“(6 – 4) • 3”

• FIRST: we have to work with inside the PARENTHESES

(6 – 4) = 2

• We can SKIP exponents because we DON’T have any EXPONENTS

• SECOND: we have to MULTIPLY

2 • 3 = 6

• We can SKIP the others (Division, Addition, and Subtraction) because we don’t need them

• Answer: 6 ☑️

Good luck on your assignment and enjoy your day!

Answer:

If you have two points, (x1, y1) and (x2, y2), you can define the exponential function that passes through these points by substituting them in the equation y = abx and solving for a and b. In general, you have to solve this pair of equations: y1 = abx1 and y2 = abx2, .

Answer:

50

Step-by-step explanation:

When two parallel lines are cut by a transversal, we see that same side exterior angles sum to 180 degrees.

It's like the blue angle and the green angle add together to sum 180. So you can construct an equation knowing this to find what x is:

[tex]2x+30+x=180\\3x+30=180\\3x=180-30\\3x=150\\x=\frac{150}{3}\\x=50[/tex]

(The reason for the answer is the first line I wrote)

Well since it's better to teach you than answer, I'll give you an explanation using #1.

Answer:

6.88

Step-by-step explanation:

In the parentheses, 1.6 has one decimal place, and so does 4.3. (count number of digits after decimal point.) So a total of 2 decimal places. (1) + (1) = (2)

Next, ignore the decimal points for now and multiply 16 × 43 = 688.

Add in the 2 decimal places, 6.88, there is your answer!

Answer:

QR = 1

Step-by-step explanation:

PR = PQ + QR

PR = x + 19

PQ = 9

So now put what you know in the equation above.

PR = 9 + 2x + 19

PR also equals x + 19

so

x + 19 = 9 + 2x + 19

x + 19 = 2x + 28

19 - 28 + x = 2x

-9 + x = 2x

-9 = 2x - x

-9 = x

===================

QR = 2x + 19

QR = 2*-9 + 19

QR = -18 + 19

QR = 1

This really is kind of a nasty question. You don't expect to get a minus number of x.

Answer:

C

Step-by-step explanation:

No, the answer is C because when you raise a number to a negative exponent it is equivalent to one over the number to the same exponent, but positive. So, [tex]6^{-7} = \frac{1}{6^{7}}[/tex] and not [tex]\frac{1}{6^{-7}}[/tex].

Answer/Step-by-step explanation:

Composition functions are functions that combine to make a new function. We use the notation ◦ to denote a composition.

f ◦ g is the composition function that has f composed with g. Be aware though, f ◦ g is not

the same as g ◦ f. (This means that composition is not commutative).

f ◦ g ◦ h is the composition that composes f with g with h.

Since when we combine functions in composition to make a new function, sometimes we

define a function to be the composition of two smaller function. For instance,

h = f ◦ g (1)

h is the function that is made from f composed with g.

For regular functions such as, say:

f(x) = 3x

2 + 2x + 1 (2)

What do we end up doing with this function? All we do is plug in various values of x into

the function because that’s what the function accepts as inputs. So we would have different

outputs for each input:

f(−2) = 3(−2)2 + 2(−2) + 1 = 12 − 4 + 1 = 9 (3)

f(0) = 3(0)2 + 2(0) + 1 = 1 (4)

f(2) = 3(2)2 + 2(2) + 1 = 12 + 4 + 1 = 17 (5)

When composing functions we do the same thing but instead of plugging in numbers we are

plugging in whole functions. For example let’s look at the following problems below:

Examples

• Find (f ◦ g)(x) for f and g below.

f(x) = 3x + 4 (6)

g(x) = x

2 +

1

x

(7)

When composing functions we always read from right to left. So, first, we will plug x

into g (which is already done) and then g into f. What this means, is that wherever we

see an x in f we will plug in g. That is, g acts as our new variable and we have f(g(x)).

g(x) = x

2 +

1

x

(8)

f(x) = 3x + 4 (9)

f( ) = 3( ) + 4 (10)

f(g(x)) = 3(g(x)) + 4 (11)

f(x

2 +

1

x

) = 3(x

2 +

1

x

) + 4 (12)

f(x

2 +

1

x

) = 3x

2 +

3

x

+ 4 (13)

Thus, (f ◦ g)(x) = f(g(x)) = 3x

2 +

3

x + 4.

Let’s try one more composition but this time with 3 functions. It’ll be exactly the same but

with one extra step.

• Find (f ◦ g ◦ h)(x) given f, g, and h below.

f(x) = 2x (14)

g(x) = x

2 + 2x (15)

h(x) = 2x (16)

(17)

We wish to find f(g(h(x))). We will first find g(h(x)).

h(x) = 2x (18)

g( ) = ( )2 + 2( ) (19)

g(h(x)) = (h(x))2 + 2(h(x)) (20)

g(2x) = (2x)

2 + 2(2x) (21)

g(2x) = 4x

2 + 4x (22)

Thus g(h(x)) = 4x

2 + 4x. We now wish to find f(g(h(x))).

g(h(x)) = 4x

2 + 4x (23)

f( ) = 2( ) (24)

f(g(h(x))) = 2(g(h(x))) (25)

f(4x

2 + 4x) = 2(4x

2 + 4x) (26)

f(4x

2 + 4x) = 8x

2 + 8x (27)

(28)

Thus (f ◦ g ◦ h)(x) = f(g(h(x))) = 8x

2 + 8x.

Answer: Direct Proportion

In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x” where k is constant in the equation. Example: y is directly proportional to x, when x = 15, y = 30.

Answer:

x = 30

Step-by-step explanation:

well from the theorem we have

[tex]\frac{15}{3}=\frac{x}{6}[/tex]

yes i know you could say that the right way is

[tex]\frac{3}{15}=\frac{6}{x}[/tex]

well if you notice they are the same only that in my way the x is in the numerator which means it will be far easier to know it's value :)

so

[tex]\frac{15}{3}=\frac{x}{6}\\\\5=\frac{x}{6}\\\\6[5]=6[\frac{x}{6}]\\\\30=x[/tex]
