If 3m = 12, what is the value of 6(m - 1) ?

Answers

Answer 1

Answer:

1. m=4

2. 6m-6

Step-by-step explanation:

well 3m=12 divide 3 on both sides m=4

so 6(m)=6m-6(1)= 6m-6

Answer 2
6m-6

Step by step:
distribute the terms, (6 x m) + (6 x - 6)
left with 6m + (-6) or 6m-6

To the nearest tenth, what is the area of a circle whose diameter is 4.4 feet?

Use 3.14 for π.

Enter your answer in the box.

ft²

Answers

Answer:

15.21= 15.2 when rounded

Step-by-step explanation:

the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2

Answer:

15.21

Step-by-step explanation:

In order to find the area, you must find the radius first.

The diameter (4.4) divided by 2 = radius (2.2)

The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).

In this situation, r, or radius =2.2.

[tex]A = \pi 2.2^{2}[/tex]

[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.

By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Step 1: Find the area of the rectangle

Area of a rectangle = base x height

Area of the rectangle = 4 x 10 = 40

Step 2: Find the area of the half-circle

Area of a circle = pi x r^2

---In this case, since we only have half of a circle, we will need to divide the area by 2 (or multiply by 1/2).

---We are also only given the diameter here. The radius of a circle is half of its diameter, therefore the radius of this half-circle is 5.

Area of the half-circle = (pi x 5^2) / 2 = (3.14 x 25) / 2 = (78.5) / 2 = 39.25

Rounded area of the half-circle = 39.3

Step 3: Find the area of the figure

Now that we know both parts of the figure, all that's left to do is add them together to find the total area.

40 + 39.3 = 79.3

Answer: 79.3

In order to factor this expression, we should divide both terms of this binomial (a polynomial with 2 terms) by 4 (the greatest common factor)

Note:- We usually factor out the Greatest Common Factor, or the GCF.

Divide:-

8

Add the terms:-

m+8

Put parentheses around them:-

(m+8)

Put 4 outside the parentheses:-

4(m+8)

notes:-

If you wonder whether or not you've factored correctly, you can use the distributive property & distribute :)

4 = 1,2,4
32 = 1,2,4,6,8,16,32
We can see that the gcf is 4
divide 4m by 4 which is m
divide 32 by 4 which is 8
which will come out to be 4(m+8)

Answer: 2, 8, 96cm^2, 35 miles

Explanation:

What we know:

We need to solve all of the given problemsWe have the information we needWe can use ratios to our advantage

How to solve:

    By using our knowledge of ratios and substitution, we can solve these problems.

Process:

First problem

Set up ratio                                                             7.5:15

Find GCF                                                                (7.5:15)/7.5

Simplify                                                                   1:2

Solution:                                                                  2  

Second problem

Set up equation                                                     (x/10) = (6/7.5)

Rewrite                                                                   (x/10) = (60/75)

Simplify                                                                   (x/10) = (4/5)

Common denominator                                          (x/10) = (8/10)

Isolate variable                                                      [(x/10) = (8/10)]*10

Simplify                                                                    x = 8

Solution:                                                                  8

Third Question

where x represents the new width, y represents the new length, and A represents the new area.

Set up equation                                                    A = xy

Substitute                                                              A = (2*4)(2*6)

Simplify                                                                  A = (8)(12)

Simplify                                                                  A = 96

Solution:                                                                96 cm^2                                                      

Fourth Question

Where x represents the unknown length in miles

Set up equation                                                    (21:3) = (x:5)

Rewrite in fraction form                                        [(21/3)] /3 = (x/5)

Simplify                                                                   (7/1) = (x/5)

GCF                                                                        5(7/1) = (x/5)

Isolate variable                                                       [(35/5) = (x/5)]*5

Solution:                                                                  35 miles = x

Answer: 2, 8, 96 cm^2, 35 milesCheck:

Problem 1:

If the scale factor is 2, then the area of a square with the side measurement of 7.5 units should be (due to areas being squared) 1/2^2 of the square with the side measurement of 15 units. Let's solve this:

(1/2^2)(15*15) = (7.5*7.5)

(1/4)(15^2) = (7.5^2)

225/4 = 56.25

56.25 = 56.25

Therefore, a scale factor of 2 is correct.

Problem 2:

If x = 8, then 8/10 should equal 6/7.5. Let's solve this:

when x = 8:

8/10 = 6/7.5

0.8 = 0.8

Therefore, x = 8 is a correct solution.

Problem 3:

If a scale factor of 2 creates the new area of 96 cm^2, then the old area of (6*4) should be (due to areas being squared) 1/2^2 of the new area. Let's solve this:

(1/2^2)(96) = (6*4)

(96/4) = 24

24 = 24

Therefore, the new area is 96 cm^2.

Problem 4:

If the houses are 35 miles apart, then 3 in./21 mi. should be equal to 5 in./35 mi. Let's solve this:

(21/3) = (35/5)

7 = 7

Therefore, the houses are 35 miles apart.

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. (5 points)

Step 2: −5x = 53

Step 4: x = -53/5

Answers

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25        WRONG

- 5x - 25 = 78

- 5x - 25 + 25 = 78 + 25

- 5x                  = 103

x = - 103/5

x = - 20,6

Answer:

Step-by-step explanation:

−5x − 25 = 78

Step 1: −5x − 25 − 25 = 78 − 25  <== this is where the error was made.

Step 2: −5x = 53

Step 3: = −5x/−5=53/−5

Step 4: x = −53/5

Right steps:

−5x − 25 = 78

Step 1: −5x − 25 + 25 = 78 + 25

Step 2: −5x = 103

Step 3: −5x/−5 = 103/−5

Step 4: x = 103

Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

Answers

Answer:

9 laps or 3600 meters.

Step-by-step explanation:

First you want to find who has ran the furthest and the least distance.

So we have Rory ran the most with 14 laps or 5600 meters and Daniel who ran the least with 5 laps or 2000 meters.Next we subtract becuase when you say to "find the difference" it means to subtract.We subtract  if you want to find the laps we do 14-5 and if you want to find the number of meters we do 5600-2000.

9 because 14-5=9 and if you want it in meter than you times that by 400

Answers

Answer:

The number b is bigger than the number a by 1/4 of a.

Step-by-step explanation:

If the number a is smaller than the number b by 1/5 of b, then

a + 1/5b = b.

Thus,

a= b - 1/5b= 4/5,

b= 5/4 a.

Consider the Expression b=5/4a:

b=5/4a= 4/4a+ 1/4a= a +1/4a

This gives that the number b is bigger than the number a by 1/4 of a.

Answers

Answer:

A

Step-by-step explanation:

I didn't learn jrf, but I believe that it is the amount of females that watch action movies divided by the total amount of females.

Amount of females who watch action movies= 99

Total females= 250

So, A seems correct.

The joint relative frequency of being male and attending a drama film, divide 124 by 229.

What is Relative Frequency?

The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency.

Two things must be understood in order to compute the relative frequency:

Total number of events/trialsA category or subgroup's frequency count

               Action           Drama              Total

Male           105                124                 229

Female       99                 151                  250

Total           204               275                 479

The joint relative frequency is the frequency in a given category divided by the total number of data values.

Here, The total number of males = 229

and, the number of males that like drama = 124

To calculate the joint relative frequency of being male and attending a drama film, divide 124 by 229.
