Answer:

0.2

Step-by-step explanation:

When rounding to a certain place, check to see if the number to the left of that place is five or above. If it is, round up. If its not, round down.

Rounding 0.18 to one decimal place, we get the value of 0.2.

To round 0.18 to one decimal place, we need to look at the digit in the tenths place (the first digit after the decimal point).

In this case, the tenths place digit is 8. To round to one decimal place, we follow the general rounding rule: if the tenths place digit is 5 or greater, we round up; if it is 4 or less, we round down.

Since the tenths place digit in 0.18 is 8, which is greater than 5, we need to round up.

Thus, rounding 0.18 to one decimal place, we get:

0.2

The rounded value is 0.2, as it is the nearest value when rounded to one decimal place.

Therefore, 0.18 rounded to one decimal place is 0.2.

Question: "What is the GCF of 30, 42, and 12?

You may ask, "How did you get the answer?"

1) Let's list out the factors of 30, 42, and 12.

30 - 1, 2, 3, 5, 6, 10, 15, 30

42 - 1, 2, 3, 6, 7, 14, 21, 42

12 - 1, 2, 3, 4, 6, 12

What are the common numbers from the list?

1, 2, 3, 6

What is the greatest number from the list of the common numbers?

6

Now let's separate the variables and find the common factor of the variables.

Variables:  

w 2 ,  w 4 ,  w * w

can also be thought of as  w 1 .

Since  

w

is the lowest powered variable and all of the other ones are greater than that. Then it means that the common factor of the variables is  

w .

Answer:

Step-by-step explanation:

Area of the quarter circle = 1/4 pi * r^2

Area of the quarter circle = 1/4 * 3.14 * r^2

Area of the triangle = 1/2 r * r = 1/2 r^2

Equation of Solution

1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2                    Subtract 1/2 r^2 from both sides

0.785 r^2 - 0.5 r^2 = 14 cm^2                           Combine the left

0.285 r^2  = 14. cm^2                                        Divide by 0.285

r^2 = 14/0.285

r^2 = 49.1228                                                     Take the square root of both sides

sqrt(r^2) = sqrt(49.1228)

r = 7.01

Not given enough information, I cannot give you the correct answer so instead, I will give you the equations you will have to do and these are not all in the order of what you have to do, but most of them are. Just follow P.E.M.D.A.S. if you know what to do. (I will put letters as answers)

step 1: (3x-1)

3 times x = Q

Q minus 1 = P

step 2: (x+5)

x plus 5 = E

Answer:

The factors of x² - 3·x - 18, are;

(x - 6), (x + 3)

Step-by-step explanation:

The given quadratic expression is presented as follows;

x² - 3·x - 18

To factorize the given expression, we look for two numbers, which are the constant terms in the factors, such that the sum of the numbers is -3, while the product of the numbers is -18

By examination, we have the numbers -6, and 3, which gives;

-6 + 3 = -3

-6 × 3 = -18

Therefore, we can write;

x² - 3·x - 18 = (x - 6) × (x + 3)

Which gives;

(x - 6) × (x + 3) = x² + 3·x - 6·x - 18 = x² - 3·x - 18

Therefore, the factors of the expression, x² - 3·x - 18, are (x - 6) and (x + 3)

Answer:

  8 in

Step-by-step explanation:

  (1200 mi)×(1 in)/(150 mi) = (1200/150) in = 8 in

The cities are 8 inches apart on the map.

_____

Additional comments

You can think of it as a units conversion problem (as above), or as a proportion:

  (map distance)/(1200 mi) = (1 in)/(150 mi)

  map distance = (1200 mi)(1 in)/(150 mi) = 1200/150 in = 8 in

__

When doing units conversion, you multiply by a scale factor that has units you want in the numerator, and units you want to cancel in the denominator. The numerator and the denominator have the same value, so multiplying by that fraction changes the units but not the value. Here, 1 in = 150 mi, so (1 in)/(150 mi) ≡ 1.

Answer:

Gina's height in inches: 63 inches

Noelle's height in inches: 67 inches

Equation: n + (n - 4) = 130

Step-by-step explanation:

n + (n - 4) = 130

n + n - 4 = 130

2n - 4 = 130

2n - 4 + 4 = 130 + 4

2n = 134

2n ÷ 2 = 134 ÷ 2

n = 67

67 - 4 = 63

Answer:

[tex]P(B) = 0.90[/tex]

Step-by-step explanation:

Given

[tex]P(A) = 0.1[/tex]

[tex]P(A\ or\ B) = 0.93[/tex]

[tex]P(A\ and\ B) = 0.07[/tex]

Required

[tex]P(B)[/tex]

To do this, we make use of:

[tex]P(A\ or\ B) + P(A\ and\ B) = P(A) + P(B)[/tex]

Make P(B) the subject

[tex]P(B) = P(A\ or\ B) + P(A\ and\ B) - P(A)[/tex]

So, we have:

[tex]P(B) = 0.93 + 0.07 - 0.1[/tex]

[tex]P(B) = 0.90[/tex]

I think just only A is the correct answer

Answer:

16 mugs

Step-by-step explanation:

Total clay bought = 45 lbs

Clay used for sculpture = 15.8 lbs

Clay left over = 17.68 lbs

Clay used for each mug = 0.72 lbs

Number of mug = x

Total clay bought = Clay used for sculpture + Clay left over + (Clay used for each mug * Number of mug)

45 = 15.8 + 17.68 + (0.72 * x)

45 = 33.48 + 0.72x

45 - 33.48 = 0.72x

11.52 = 0.72x

x = 11.52/0.72

x = 16

Number of mug = x = 16 mugs
