Answer:

6, 12, 18, 24, 30, 36, 42, 48, 54 (the bolded numbers go in the box)

Step-by-step explanation:

1. To find the multiples of 6 between 6 and 54, we have to multiply 6 by numbers from 1 to 9.

6 × 1 = 66 × 2 = 126 × 3 = 186 × 4 = 246 × 5 = 30 6 × 6 = 36 6 × 7 = 426 × 8 = 48 6 × 9 = 54

Therefore, the multiples of 6 between 6 and 54 are 6, 12, 18, 24, 30, 36, 42, 48, 54. (again, the bolded numbers go in the boxes)

Solve for x: 7x = 4x + 27
x =

Answers

Answer:

x = 9

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

[tex]7x - 4x = 4x + 27 - 4x[/tex] [tex]3x = 27[/tex]

Step 2: Divide both sides by 3.

[tex]\frac{3x}{3} =\frac{27}{3}[/tex] [tex]x = 9[/tex]

Step 3: Check if solution is correct.

[tex]7(9) = 4(9) + 27[/tex] [tex]63 = 36 + 27[/tex] [tex]63 = 63[/tex]

Therefore, x = 9.

7x = 4x +27
3x = 27
x = 9

Math

Answers

Answer:  If you measure out a 10k course and then time how long it takes you to ride it, that will tell you which speed range to use and what time to input. If you weigh 185 pounds and fall into the 12 to 13 mph range, it will take you about 30 minutes to pedal 10k — which means that according to the ACE estimates, you will burn about 335 calories.

Step-by-step explanation:

Hope this helps!

Answer:

0.2km/min or 12.7km/hour

Step-by-step explanation:

speed = distance ÷ time

speed = (10km + 8km) ÷ (45 mins + 40 mins)

= 18 ÷ 85

= 0.21176...km/min ≈ 0.2km/min

To convert 0.21176...km/min into km/hr, you multiply by 60

0.21176...km/min × 60 = 12.70588...km/hr ≈ 12.7km/hr

NEEDS TO BE STEP BY STEP

Answers

The equation in point-slope form to represent the time y it took to download x songs is; (y - 35) = 7(x - 5)

Since it took 35 seconds for 5 songs to download

and it took 42 seconds for 6 songs to download

In essence, we can represent the information as;

(5, 35) and (6,42)

To find the slope of the equation; we have;

Slope, m = (42-35)/(6-5)

m = 7

In essence, the equation in point-slope form to represent the time y it took to download x songs is;

(y - 35) = 7(x - 5)

The function g(x) is a transformation of the cube root parent function, f(x) = 3vx
What function is g(x)?

Answers

Answer:

C.  g(x)=3√x+4+3

Step-by-step explanation:

g(x) shift left 4, shift up 3, with no compression or stretch.

a=1

h=-4

k=3

The function f(x) after the transformation can be written as -

g(x) = [tex]$\sqrt[3]{x-4} +3[/tex]

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of function as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is that function g(x) is a transformation of the cube root parent function f(x) = [tex]$\sqrt[3]{x}[/tex].

The function f(x) is shifted up by three units and left by 4 units. So, we can write the rule for the function transformation as -

g(x) = [tex]$\sqrt[3]{x-4} +3[/tex]

Therefore, the function f(x) after the transformation can be written as -

g(x) = [tex]$\sqrt[3]{x-4} +3[/tex]

In a distribution with a mean of 100 and a standard deviation of 15, the probability that a score
will be 115 or higher is _____ Please show all your work.

Answers

Using the Zscore principle, the probability of obtaining a score which will be 115 or higher is 0.15866

Given the Parameters :

Mean, μ = 100Standard deviation, σ = 15 Score, X ≥ 115

Zscore = (X - μ) ÷ σ

Zscore = (115 - 100) ÷ 15

Zscore = 1

Using a normal distribution probability ;

P(Z ≥ 1) = 1 - P(Z ≤ 1)

P(Z ≥ 1) = 1 - 0.84134

P(Z ≥ 1) = 0.15866

Therefore, the probability is 0.15866
