Answer:

x=19

Step-by-step explanation:

3x-3=[6(x-10)]

3x-3=6x-60

-3x   -3x

-3=3x-60

+60   +60

57=3x

x=19

3x-3            6(x-10)

3(19)            6(19-10)

57  -3             6(9)

54                   54

These angles are vertical angles which means they are equal

Answer:

[tex]58x-54=468[/tex]

Step-by-step explanation:

Number of repeat customers = 40

Amount charged from each of the repeat customers = $ x

So,

amount charged from 40 customers = $ 40 x

Number of new customers = 18

As Michel charged each of the new subscribers $3 less than the amount charged from each of the repeat customers,

amount charged from each of the new customers = $ (x - 3)

So,

amount charged from 18 new customers = $ 18(x - 3)

Total amount charged from repeat and new customers = [tex]\$[(40x)+18(x-3)]=\$40x+18x-54=\$58x-54[/tex]

As Michel collected $468 for delivering newspapers,

[tex]58x-54=468[/tex]

Answer:

3/2

Step-by-step explanation:

3^-4 x 2^3 x 3^2/2^4 x 3^-3

base 3 will be numerator and base 2 will be denominator:

3^-4 * 3^2 * 3^3 / 2^4*2^-3

Now add the exponents of the base:

3^-4+2+3/ 2^4-3

3^-4+5/ 2^1

3/2

The correct option is 3/2

Answer:

3/2

Step-by-step explanation:

Answer:

The correct option is;

c. The horizontal axis labeled Hours Driven goes from 0 to 15 in increments of 1 and the vertical axis labeled Miles Remaining goes from 0 to 150 in increments of 10. The line starts at left parenthesis (0, 0), and passes through (1, 65) and (2, 130)

Step-by-step explanation:

The given parameters are;

The speed of the truck = 65 miles per hour

The length of the highway = 130 miles

Therefore, from the given information, we have;

The time, t, it will take the truck to arrive at the end of the highway is given as follows;

Time = Distance/speed = 130/65 = 2 hours

Therefore, if the truck timing starts from the point (0, 0), we have;

The points on the straight line (constant) speed graph are;

(0, 0), (1, 65), and (2, 130)

Paragraph:

Functions are a special kind of relation. At first glance, a function looks like a relation. A function is a set of ordered pairs such as { (0, 1), (5, 22), (11, 9)}. Like a relation, a function has a domain and range made up of the x and y values of ordered pairs.

Answer:  So our two integers are 17 and 45.

Step-by-step explanation:

The two integers are 17 and 45, See how we got it. X+Y=62. Substitute our first expression here for y, we have X+2X+11 =62.

Given that,

the two numbers are consecutive(also odd)

The two numbers are

x and x + 2

Sum of the numbers = 62

x + (x + 2) = 62

x + x + 2 = 62

2x = 62 - 2

2x = 60

x = 60/2

x = 30

Therefore, the two numbers are x = 30 and x + 1 = 32

Answer:

y = 3x+9

Step-by-step explanation:

We can use the slope intercept form

y = mx+b

where m is the slope and b is the y intercept

y = 3x +b

Substitute the point into the equation

6 = 3(-1) +b

6 = -3+b

Add 3 to each side

6+3 = -3+3+b

9 = b

y = 3x+9

Answer:

C.

Step-by-step explanation:

The answer is C. when using the formula C=2*pi*r and A=pi*r^2.

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.

Answer:

The temperature changed by [tex]-12^\circ F[/tex] overnight.

The temperature changed by [tex]-1^\circ F[/tex] overnight each hour.

Step-by-step explanation:

Given that:

Temperature at 7 PM last night = [tex]10^\circ F[/tex]

Temperature at 7 AM the next morning = [tex]-2^\circ F[/tex]

a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM

[tex]\Rightarrow -2-10 =\bold{-12^\circ F}[/tex]

Negative sign indicates that the temperature has decreased.

b. Change in temperature each hour:

Divide the Change in temperature with the number of hours.

[tex]\Rightarrow \dfrac{-12}{12} = \bold{-1^\circ F}[/tex]

Negative sign indicates that the temperature has decreased.

Answer:

14 degrees

Step-by-step explanation:

12 + 25 - 23 = 14

Given:

Kinetic energy (KE)= 100,000 J

Mass (m)= 800 kg

To find:

The velocity of the object to the nearest hundredth.

Solution:

We know that,

[tex]KE=\dfrac{1}{2}mv^2[/tex]

where, KE is kinetic energy (in J), m is mass (in kg) and v is velocity (in m/s).

Put KE=100000 and m=800 in the above formula.

[tex]100000=\dfrac{1}{2}(800)v^2[/tex]

[tex]100000=400v^2[/tex]

Divide both sides by 400.

[tex]\dfrac{100000}{400}=v^2[/tex]

[tex]250=v^2[/tex]

Taking square root on both sides.

[tex]\sqrt{250}=v[/tex]

[tex]v=15.8113883[/tex]

[tex]v\approx 15.81[/tex]

Therefore, the velocity of the object is 15.81 m/s.

Answer:

rational number

Step-by-step explanation:

Answer:

9.4606x10^12 kilometers

Step-by-step explanation:

The scientific notation is numbers is exponents with a base of 10. As this number is 9.4606 trillion, we need to use 1 trillion as 10^12. Then we multiply by 9.4606 to get 9.4606x10^12 km. Hope it helps!

Answer:

25%

Happy To Help!

===============================================

Work Shown:

A = old value = 3000

B = new value = 2250

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (2250-3000)/3000 ] * 100%

C = (-750/3000) * 100%

C = -0.25*100%

C = -25%

Since C is negative, we have a 25% percent decrease.

Another indication we have a percent decrease is that B < A.

Answer:

the answer is 427miles in 7 hours

Step-by-step explanation:

Answer:

427 miles in 7 hours.

Step-by-step explanation:

All we need to do is figure out how many miles per hour he's traveling, and then add it to the pre-existing 6 hour number we already have.

So, he drove 366 miles in 6 hours. We need to find out how many miles per hour (MPH) he's doing. To do this all we need to do is divide the amount of miles he's gone (366) by the number of hours it's taken him (6).  It looks like this:

366 ÷ 6 = 61.

So he's goes 61 miles every hour. Now all we need to do is add up until we hit 7 hours. We already know he went 366 miles in 6 hours, so we only need to add 61 to 366 once.

366 + 61 = 427.

427 is your answer.

Hope this helps and have a nice day!
