Solve for z: 14/5 = z/25?

Answer:

(g o f)(x) = x

Step-by-step explanation:

Given the functions f(x) = 2/x and g(x) = 2/x

(g o f)(x) = g(f(x))

g(f(x)) = g(2/x)

Replace x with 2/x in g(x)

g(f(x)) = 2/(2/x)

g(f(x)) = 2 * x/2

g(f(x)) = 2x/2

g(f(x)) = x

Hence the composite function g o f)(x) is x

Answer:

400 calories

Step-by-step explanation:

One cupcake has 80 calories. 80 x 5 = 400

Answer:

400 Calories

Step-by-step explanation:

If there are 240 calories in 3 servings, In one serving there must be 80 because

240/3 = 80

And since there are 80 calories in one serving, in 5 servings there will be 5 times the amount of calories there is in one serving so

5 * 80 = 400

Answer:

180

Step-by-step explanation:

Explanation: In a triangle, there can only be one obtuse angle. Additionally, all the angle measures must add up to 180.

Answer:

100 bicycle

Step-by-step explanation:

Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.

x is the number of bikes

To minimize the cost, dC/dx = 0

dC/dx = 10x - 1000

Since dC/dx = 0

0 = 10x - 1000

-10x = -1000

x = 1000/10

x = 100

Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

Answer:

Step-by-step explanation:

Answer:

8x - 4y = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 and c = - [tex]\frac{3}{4}[/tex] , then

y = 2x - [tex]\frac{3}{4}[/tex] ← in slope- intercept form

Multiply through by 4 to clear the fraction

4y = 8x - 3 ( subtract 4y from both sides )

0 = 8x - 4y - 3 ( add 3 to both sides )

3 = 8x - 4y , or

8x - 4y = 3 ← in standard form

So many confusing details. So, I rephrase the question as:

Four volunteers picked up litters from the park.

Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x

Answer:

[tex]x = 72[/tex]

Step-by-step explanation:

Let:

[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]

From the [rephrased] question, we have:

[tex]D = S - 15[/tex]

[tex]S = 12 + P[/tex]

[tex]P = \frac{1}{4}V[/tex]

[tex]V = 9 + D + S + P[/tex]

Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]

[tex]D = 12 + P - 15[/tex]

[tex]D = P+12 - 15[/tex]

[tex]D = P-3[/tex]

Make V the subject in [tex]P = \frac{1}{4}V[/tex]

[tex]V = 4P[/tex]

Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]

[tex]4P= 9 + P - 3 + 12 + P +P[/tex]

Collect like terms

[tex]4P - P -P-P= 9 - 3 + 12[/tex]

[tex]P= 18[/tex]

Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]

[tex]S = 12 +18[/tex]

[tex]S = 30[/tex]

Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]

[tex]D = 30 - 15[/tex]

[tex]D =15[/tex]

Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]

[tex]V = 9 + 15 + 30 + 18[/tex]

[tex]V = 72[/tex]

x represents the number collected by Vaughan.

So:

[tex]x = 72[/tex]

Answer:

Well you have to solve each problem first to make them the same. Let's do decimals.

a) The square root of 58 is 7.61577310586. Let's round that to 7.62. You can solve this with a calculator.

b) Simply -32.0, since it is a whole negative number.

c) I think there's a typo, 'C' is the second 'b)', which is 49/7. 49 divided by 7 is seven, hence the decimal would be 7.0

d) 2.65 repeated, already a decimal, does not need changed.

e) The square root of 6 is 2.44948974278. Let's round that to 2.45.

f) is just 0. no decimal, just 0.

Now that you have these as the same form of number, you have to put them into one of these categories. The categories can be found below.

Any square root number is irrational. Any never ending number is irrational, like pi, but there are none of those in this situation. So a, and e are all irrational.

Any repeated number, in this case, 2.65 repeated, is a rational number, as is any decimal or fraction, but there are none of these, so d is rational.

-32 is and integer, because it is a negative whole number, so b is an integer.

Whole numbers are any numbers 0+. So f is the only answer that is a whole number.

Natural numbers are any numbers 1+. So c or the second b is a natural number.

Hope this helps :)

Answer:

[tex]n = 144m^2 - 1[/tex]

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

__________________________________________________________

According to the question ,

[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]

Lets multiply both the sides by 4.

[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]

[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]

It can be also written as :-

[tex]=> \sqrt{(n + 1)} = 12m[/tex]

Lets square both the sides.

[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]

[tex]=> n + 1 =144m^2[/tex]

[tex]=> n = 144m^2 - 1[/tex]

Step-by-step explanation:

The solution is, A. & E. x=15/3/4.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

given that,

3/4x = 15

x= 15÷3/4

x=15/3/4

Hence, The solution is, A. & E. x=15/3/4.

Answer:

This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion.

Step-by-step explanation:

Undercoverage bias occurs when the sample chosen for a research is not representative of the entire population. Most times when research involving surveys to obtain the opinions of people on a subject matter, the entire population affected by the issue cannot be surveyed. A sample that represents the true population can be used for this research.

In the survey above, the sample that was surveyed was not representative of the entire population of citizens paying taxes on entertainment tickets. The selection process does not represent the true population.

Answer:

14kilometers

Step-by-step explanation:

diameter=2*radius.

Answer:

43.35 years

Step-by-step explanation:

From the above question, we are to find Time t for compound interest

The formula is given as :

t = ln(A/P) / n[ln(1 + r/n)]

A = $2500

P = Principal = $200

R = 6%

n = Compounding frequency = 1

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06/1)] )

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06)] )

t = 43.346 years

Approximately = 43.35 years

Answer:

He has 1/3 of a jug left.

Step-by-step explanation:

He starts with 1 1/3 jugs.

He uses 3/4 of 1 1/3 jugs.

A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since

1 - 3/4 = 4/4 - 3/4 = 1/4

That means he has 1/4 of 1 1/3 jugs left.

We need to multiply 1/4 by 1 1/3.

1/4 * 1 1/3 =

= 1/4 * 4/3

= 4/12

= 1/3

Answer:

BA = 22.57

Step-by-step explanation:

perimeter = 60

2BZ + 2ZA = 60

BZ + ZA = 30,    BZ = 30 - ZA

tan 25° = 0.4663

0.4663 = ZA/BZ = ZA/(30 - ZA)

multiply both sides by (30 - ZA):

0.4663(30 - ZA) = ZA

simplify:

13.99 -0.4663ZA = ZA

add 0.4663ZA to each side:

13.99 = 1.4663ZA

divide both sides by 1.4663:

ZA = 9.54

BZ = 30 - 9.54 = 20.46

BA² = 9.54² + 20.46²

BA² = 509.62

BA = 22.57
