Answers

Answer 1

Answer:

ANSWER:

The temperature in Small ville, six hours ago was 13 degrees.

SOLUTION:

Given, current temperature in Smallville is 20 degrees.

And this is 6 degrees less than twice the temperature that it was six hours ago.

We need to find what was the temperature six hours ago.

Let the temperature six hours ago be x.

Then, 2x - 6 = 20 [ according to the given information

2x = 20 + 6

2x = 26

x = $(26)/(2)$

x = 13 degrees.

Temperature six hours ago was 13 degrees

Hence, the temperature in smallville , six hours ago was 13 degrees.

The perimeter of a rectangular field is 354 yards. If the width of the field is 82 yards, what is its length

Answers

Length is 95 yards.

The perimeter of a rectangle is the sum of four sides. The four sides are either its length or width.

A rectangle has four sides where its angles are all right angles and its opposite sides are congruent or of equal size.

Perimeter = 2length + 2width ==> P = 2L + 2W

354 = 2L + 2(82)
354 = 2L + 164
to get the length. we must transfer all like signs.
2L = 354 - 164
2L = 190
2L / 2 = 190 / 2
L = 95 yards.

The answer of the length is 95

Are slopes just for people who ski? No, they’re everywhere! Take a look around you. They’re in skateboard ramps, roller coasters, accessibility ramps on buildings, loading ramps on the backs of trucks, and even in the angle of a plane taking off or landing. A. Find an example of a slope in real life. Your example can be from the Internet, videos, magazines, newspapers, or right outside your window. Take a picture or a screenshot, or create a drawing, of your example. Put this in a PowerPoint slide. Next to your image, create a graph of the slope. You do not have to be exact. Just estimate what you think the slope should be. Create a post with your slide. Explain your graph and describe the real-life example that it is based on. Example: This is my new skateboard ramp. It is approximately 11 ft long by 8 ft tall. B. Go to another student’s post and write the equation for that student's line in point-slope form, standard form, or slope-intercept form. Explain your reason for choosing that form. C. Respond to replies to your own post. Covert the equation that was written about your graph to another form. Be sure to check back regularly to participate in the discussion with your fellow students and teacher.

HELPP plz in. 17 thank u so much

Answers

In the table, you can see level 1 is 5 to the first power, level 2 is 5 to the second and go on.
so in level 6 would be 5 to the sixth power
so the answer to first one is 5^6
for the second question you should know that level 2 is 5^2 and level 6 is 5^6 so 5^6/5^2 = 5^4 is the answer :))))
I hope this is helpful

20% of 150 is what number?

Answers

To find a number's , let's say "x%" you should multiply that number by, $\frac { x }{ 100 }$ , so we want to find 150 's 20% , so we will multiply , 150 with $\frac { 20 }{ 100 }$ , so :

$150\cdot \frac { 20 }{ 100 } \n \n We\quad can\quad simplify\quad \frac { 20 }{ 100 } \n \n \frac { 20 }{ 100 } =\frac { 2\cdot 10 }{ 10\cdot 10 } =\frac { 10 }{ 10 } \cdot \frac { 2 }{ 10 } =1\cdot \frac { 2 }{ 10 } =\frac { 2 }{ 10 } \n \n 150\cdot \frac { 2 }{ 10 } =\frac { 150\cdot 2 }{ 10 } =\frac { 300 }{ 10 } =30\n \n %20\quad of\quad 150\quad is\quad 30$

20/100 * 150 = 30

so the answer is 30

Does anyone know of a rectangular has an area of 30square meters and a perimeter of34 Meter. What are the dimensions of a rectangle

Answers

Yes...
to find the answer, first find all of the factors of 30
then, find the perimeter if those two were the two lengths of the rectangle...
until you find a pair of side lengths that make the perimeter = 34

To begin...
1 and 30 --> A=30; P=62 X

And so on

Hope this helps!
