The number of trips that Molly and Tess did was 7.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

As per the given,

Molly has $280 in her bank account and spends $40 on every trip.

Number of trips = Account balance / spent in every trip

⇒ $280/$40 = 7

Hence "The number of trips that Molly and Tess did was 7".

Answer:

Hidden question 1: How much change did Joshua get back after paying for his supplies.

Hidden question 2: How many puppies have spots?

(I hope this is what you meant by hidden questions. If you meant something like rearranging the words I am so sorry.)

Answer:

The answer is below

Step-by-step explanation:

A composite function is a function which is placed inside another function, this type of function can be calculated by substituting one function into another function.

If two functions g(x) and f(x) are inverses, then each will reverse the effect of the other. That is, (f○g)(x)=f(g(x))=x and (g○f)(x)=g(f(x))=x.

Given that F(x) =(x+4)/3 and g(x) = 3x – 4

a) (f o g)(x) = f[g(x)]

   = f(3x - 4)

   = [(3x - 4) + 4]/3

   = [3x - 4 + 4]/3

   = 3x / 3

   = 3

b) (g o f)(x) = g[f(x)]

   = g[(x + 4)/3]

   = 3(x + 4)/3 - 4

   = x + 4 - 4

   = x

We can see that (f o g)(x) = (g o f)(x) = x. Hence the functions are inverse functions.

Explanation: Proportion is a share or part of a whole in mathematics and some other subjects. It is also related with ratio. For example: 5:7

Answer:

a part comparative relation to a whole

Related to ratio

Eg: 2:5 {read as (two is to 5)}

Answer:

.80

Step-by-step explanation:

Hey There,

Cosine = adjacent / hypotenuse

the adjacent of c is 16

the hypotenuse is 20

so cos C = 16/20 or .80

Answer:

Step-by-step explanation:

cos=(adjacent side)/(hypotenuse)

cosC=16/20

cosC=4/5

cosC=0.80 (to nearest hundredth)

Answer:

135

Step-by-step explanation:

Ratio = 3 : 9

Angles are : 3x , 9x

3x + 9x = 180         {supplementary angles}

   12x   = 180  {divide both side by 12}

       x = 180/12

x = 15

Larger angle = 9x = 9*15 = 135

The answer is below

Step-by-step explanation:

A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.

The total surface are of a triangular prism is given as:

A = bh + 2ls + lb

where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.

Given that:

b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.

Therefore:

A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²

Therefore 183 ft² of fabric is needed to make the tent

Actual distance = distance on map x the scale:

3 inches x 15 miles per inch = 45 actual miles.

Answer:

Step-by-step explanation:

If the distance across the floor from one mark to the other is [15] inches then the [Pythagorean Theorem] says that because 12^2+9^2=[15]^2, a right triangle is formed.

Answer:

y = -8/3x - 11

Step-by-step explanation:

(-6, 5) and (-3, -3)

Slope:

m=(y2-y1)/(x2-x1)

m=(-3-5)/(-3+6)

m=(-8)/3

m= -8/3

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -8/3(x + 6)

y - 5 = -8/3x - 16

y = -8/3x - 11

Answer:

77 5/8

Step-by-step explanation:

a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4

= 24/4

b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

c) Write a previous answer (new numerator 27) over the denominator 4.

Conversion a decimal number to a fraction: -11.5 = -115/10

= -23/2

a) Write down the decimal -11.5 divided by 1: -11.5 = -11.5/1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

-11.5/1

= -115/10

c) Simplify and reduce the fraction

-115/10

= -23 * 5/2*5

= -23 * 5/2*5

= -23/2

Multiple: 27/4

* (-11.5) = 27 · (-23)/4 times5

= -621/8

Answer: Amount of Money Barak  earned last week =$125

Step-by-step explanation:

Amount of money Barak spent= $20

Amount of money spent = 16% of Money earned (X)can be represented as

16%  x  X =20

0.16 x X  =20

X = Money earned last week = 20/ 0.16= $125

Answer:

8

Step-by-step explanation:  

x=average

(x+x+x+x)/4=average

to increase x by 2 you add 2

x+2=average

(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2

you'd have to increase the sum by 8 to make the numbers' averages' go up by 2

Answer:

1.-6 is the Y intercept

2.3/14

3.empty set

step by step explanation:

1.Y= mX-B

so B is -6

2.11-2raised3/14

2raised 3 is 8

that means 11-8/14=3/14

3. 7(x+3)= 7x-8

7x+21=7x-8

7x-7x=-8-21

0=-29

over here X is gone its so empty set

Answer:

x = 17/18

Step-by-step explanation:

-5(7-8x) -7x = -(3x+1)

-35 + 40x - 7x = -3x - 1

-35 + 33x = -3x - 1

33x + 3x = -1 + 35

36x = 34

x = 34/36

x = 17/18
