1.5(6)

9

Answer:

9

Step-by-step explanation:

I chose 9 because first you have to add 4+2 because it's in parenthesis and the other with parenthesis has no other numbers so 4+2 first then 4+2 is 6 then you multiply 6 by the 3 in the parenthesis because it is in the parenthesis then divide by 2 because 1/2 is basically dividing by 2

What is the measure of an angle, in degrees, if its supplement is six times its complement?

Answers

Answer:

72 degrees.

Step-by-step explanation:

We can name the measure of the angle x.

We can name the measure of the complement of it y.

Note that complementary angles add up to 90 degrees and supplementary angles add up to 180 degrees.

Using this info, we can set up two equations.

x+y=90

x+6y=180

Subtract the first equation from the second to eliminate x. You can do both ways, but I prefer to keep the equation positive.

x+6y=180

-x -y   -90

5y=90

Divide both sides by 5.

y=18

The complement is 18, now we can plug that in to find x.

x+18=90

Subtract 18 from both sides.

x=72

The measure of the angle is 72 degrees.

you have to find the unit rate first then try to solve

Step-by-step explanation:

Answer:

1/4 minutes

Step-by-step explanation:

1 minute = 60 seconds

3 minutes = 180 seconds

3 minutes and 15 seconds = 195 seconds

13 miles/195 seconds

195/13 = 15

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams? y = a * (.5) ^ (1/7)

Answers

Answer:

[tex]t \approx 50.4\,min[/tex]

Step-by-step explanation:

The time constant of the element X is:

[tex]\tau = \frac{13\,min}{\ln 2}[/tex]

[tex]\tau = 18.755\,min[/tex]

The decay function has the following form:

[tex]\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }[/tex]

[tex]t = -\tau \cdot \ln \frac{m}{m_{o}}[/tex]

[tex]t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)[/tex]

[tex]t \approx 50.4\,min[/tex]

Find the value of x.

F) 6m
G) 7.5m
H) 15m
I) 21m

Answers

Answer:

x = 6 m

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here A = 60, h = 8, a = 9 and b = x , thus

[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is

4(9 + x) = 60 ( divide both sides by 4 )

9 + x = 15 ( subtract 9 from both sides )

x = 6 m

Find the mean absolute deviation for the set below:

62, 71, 83, 110, 501, 94, 227

Answers

Answer:

(MAD) mean absolute deviation: 114.2

Step-by-step explanation:

Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164

164 - 62 = 102

164 - 71 = 93

164 - 83 = 81

164 - 110 = 54

164 - 501 = 337

164 - 94 = 70

164 - 227 = 63

Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 =  114.2

Answer:

Step-by-step explanation:

First, add all the numbers and count the total amount of numbers.

Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.

Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)

Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.

Then, you have the M.A,D ( Mean Absolute Deviation )

Factor this polynomial completely.

Given the general form: ax + by = c How can we rewrite this general for the equation of a line, so that it is in slope intercept form? (a, b, and c are real numbers other than 0.) Hint: Substitute in values for a,b,c if you are confused) YOUR FINAL ANSWER SHOULD HAVE a,b,c in it. *

Answers

Answer:

[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex] or [tex]y = \frac{c-ax}{b}[/tex]

Step-by-step explanation:

Slope intercept form is y = mx + b, so you rewrite it to equal y.

ax + by = c

by = c - ax

y = (c - ax) / b

[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex]

In the image, all the lines overlap. This proves that all the equations are equal to each other.

In the figure, b and c are parallel lines. Which of the following statements are true?

1.Joe claims the measure of angle 3 is equal to 90 degrees. Is he correct, why or why not?
2.state the measure of angle 5 and how you know!

Here is the figure thank you for any help!! :)

Answers

1) Not True, because angles on a straight line=180 degrees. So 72+90=162 not 180, 180-72=108, angle 3 is 108 degrees.
2) Angle 5=72 degrees because angle 5 is alternate to angle 72 degrees.

First, convert from meters to kilometers. 20 meters is 0.02 kilometers.

Now that you have km/s, convert 0.02 km/s into km/h by multiplying it by the number of seconds in an hour. There are 3,600 seconds in an hour. Multiply 0.02 km/s by 3,600 secs/h to get 72km/h!
