If n stands for Amy’s age, which of these sentences could be used to find her age?

Answer:

-18

Step-by-step explanation:

The absolute value is only on the 9, and the absolute value of positive 9 is positive 9. Multiply by negative 2 and you get -18.

Answer:

The answer is

B. 6, 8, 11, 1, 7, 14, 10

C. 14, 10, 6, 9, 11, 8, 1

Step-by-step explanation:

Answer: 8

Step-by-step explanation:

QS = RS + QR

3x = 2x + 3x-8

3x = 5x - 8

8 = 2x

8/2 = x

4 = x

RS = 2x = 2(4) = 8

Answer:

To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.

Answer:

y = -x -1

Brainliest, please!

Step-by-step explanation:

(4, -5)(-6, 5)

y = mx + b

m = slope, b = y-intercept

m = 10/-10

m = -1

y = -1x + b

We can plug in (4, -5):

-5 = -1(4) + b

-5 = -4 + b

b = -1

y = -x - 1

Answer:

$163.8 more.

Step-by-step explanation:

Let's use the formula Principle × Rate × Time, or PRT to find our simple interest. Let's fill in the blanks. Our principle is $630. Our rate is 6.5% and our time is 4 years. Next, we multiply all this. $630 × 13/200 × 4. Our answer would be 163.8. I hoped this helped.

Answer:

Step-by-step explanation:

Sum of all the angles of 12 sided polygon= (n -2)*180

   = (12 - 2 )*180 = 10 * 180 = 1800

Four interior angle each of xº +  8 interior angles each of 2xº = 1800

4*x  + 8*2x = 1800

4x + 16x = 1800

20x = 1800

x = 1800/20

x = 90°

Answer:

x = 90

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 12 , then

sum = 180° × 10 = 1800

There are 12 interior angles

Given 4 are x, then 8 are 2x , so

4x + 8(2x) = 1800

4x + 16x = 1800

20x = 1800 ( divide both sides by 20 )

x = 90

Answer:

1_ 129 , 51

2_ b

3_ 40

Step-by-step explanation:

1_ we can represent the bigger angle with x and smaller one with y

and as given, y is smaller than x by 78

so y = x - 78 (1)

as x + y = 180

we put y as we did in (1)

x + x - 78 = 180

so 2x = 258

so x = 129

and y will be 51

2_ from the figure we find the two angles form one angle = 90 degree

3_ from the defenition of complementary angles

m(c) + m(d) = 90

7r + 5 + 8r + 10 = 90

15r + 15 = 90

r = 5

so m(c) will be equal 7*5 + 5 = 40

Answer:

0.0300300030000...

Step-by-step explanation:

An irrational number has endless non-repeating digits to the right of the decimal point. They can be written as decimals, but not as fractions.

1632 can be written as 3264/2

0.25 can be written as 1/4

0 could be written as 0/0

but 0.0300300030000 cannot be written as a fraction, and it satisfies the condition of an irrational number having endless non-repeating digits to the right of the decimal point.

Answer:

The answer is C, 135 + 100h = 535.

Step-by-step explanation:

H can't be multiplied by 135, since that's only for one hour.  That value never changes, so it can't be A.  It's not B because that implies that she starts out by charging $235 for the first hour, plus the # of additional hours, which doesn't make sense.  And it's not D because the total amount of $ that she receives must EQUAL 535, but there is another number on the same side with 535.  Therefore, the only answer that remains is C.  

P.S. She worked 4 additional hours.

Answer:

Property

Step-by-step explanation:

In order to fully understand the actual velocity of the airplane bearing, we've carefully drawn out the sketch.

From the image below, by applying the cosine rule to calculate the actual velocity of the plane from the starting point, we have:

b² = a² + c² - 2ac Cos B

where;

b² = (50² + 325²) - (2 × 50 × 325 × Cos 115°)

b² = 2500 + 105625 - (32500 ×  (-0.4226))

b² = 108125 - (-13734.5)

b² = 121859.5

[tex]\mathbf{b =\sqrt{121859.5 }}[/tex]

b = 349.08 mph

Therefore, we can conclude that the actual velocity of the airplane from its starting point is 349.08 mph.

After 4 hours of snow melting, there would be 8 inches of snow with the rate of 2.5 inches per hour Katherine would have on her lawn and after t hours the snow would be = 18 - 2.5*t inches.

In this question, the amount of snow melted is required to calculate to know the amount of snow on the lawn, can be calculated by:

Given:

The total amount of snow = 18 inches

Rate of melting = 2.5 inches

Time = 4 hours

Solution:

The amount melted needs to be calculated first in order to find left snow, therefore, putting values in the formula mention above,

the melted amount = rate of melting × time

the melted amount = 2.5 × 4 inches

the melted amount = 10 inches

Then the final amount would have on the lawn =  starting amount−melted snow

=  18−10 inches

= 8 inches

Part b) Snow after t hours:

Starting amount=  18 inches

Melted snow=  inches per hour×t

= 2.5×t

= 2.5t

Final amount = starting amount−melted snow

= 18 -2.5t

Thus, the correct answer is - 8 inches and 18 -2.5t

Answer:

a. 41

b. -31

c. 25/3, no

Step-by-step explanation:

when it says find f(14) the number inside the parenthesis is x, so you just plug that number into the equation which in this case is 3x-1. for c it says find the input if the output is 24. so basically the output is f(x) or y and the input is x. so 3x-1 = 24.
