If the perimeter of this polygon is 83 meters, what is the length of the missing side?


A. 24 m
B. 34 m
C. 59 m
D. 83 m

Answer:

Positive 0.05

Step-by-step explanation:

[tex](-1,-.3) (1, -.2)[/tex]

[tex]m=\frac{-.2-(-.3)}{1-(-1)} =\frac{-.2+.3}{1+1} =\frac{0.1}{2} =0.05[/tex]

Answer:

3.391 Gallons Per Minute

Step-by-step explanation:

78/23=3.391

Round 3.391 to 3.4

Answer:

≈3.39130434783 gallons per minute

Step-by-step explanation:

The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:

[tex]78 : 23[/tex]  OR  [tex]\frac{78}{23}[/tex]

We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:

[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]

And of course, if there's a need to round, go ahead.

And please do not waste water!

Answer:

2

Step-by-step explanation:

-6*-9=54

-9/-3=3 and 3 cubed=27

54/27=2

Answer:

Well all you need is 2 points to calculate slope

You can follow the equation,

{y2-y1 / x2-x1} = slope

-2-1=-3

4-0=4

-3/4

-3/4 is the slope

Answer:

7 to the power of 7 ( which is 823,543 )

Step-by-step explanation:

Why? well if 4+3 is 7 the exponent would be 7 to because if you look carefuly it says with an exponent of 2 + 5 and 2 + 5 is 7 so your exponent is 7.

I hope This is right!

Answer:

40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Answer:

 40

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.

Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

Answer:

48

Step-by-step explanation:

20 scrunchies=3 dollars

7.25 dollars = ?

1 dollar=6.66666666

0.25 dollar=1.666666666666

7*6.66666666=46.666666

Answer:

510.7817 or 511

explanation:

First you’re going to have to substitute 10 in for x, so

Y= 52.7515(10) -16.7333

Y=527.515-16.7333

Then subtract

Y=510.7817

Answer:

$84

Step-by-step explanation:

1. If 20% is marked off, then you are selling it for 80%.

2. 455 * 80% = 364

3. Since you are finding the cost markup from 280, then 364-280=84

Answer:

A. 6, 7, 8, 9 ;

B. 2, 5, 8, 11 ;

C. 5, 8, 13, 20 ;

Answer:

$700

Step-by-step explanation:

25% = 1/4

the sales would be 100% or 4/4

So if commission rate is 1/4, to find the sales we multiply this by 4:

$175*4= $700

The sales would amount to $700

Hope this helps :)

Answer:

3 1/3 metric tons per hour

Step-by-step explanation:

the equation is y=mx + b. the m (or the thing that comes before the x in the equation) is your slope, the y intercept is the last number. if the last number is preceded by a minus sign, the intercept number is negative

Answer:

For example, number 1's slope is 5/3.  On a graph, you would go up 5 (not in block, but in numerical value) and right 3.   The y-intercept is -2.  This is where your line starts on the graph.

Step-by-step explanation:

y=mx+b       b= y-intercept   y-intercept=where the line crosses the y-axis    m=slope         slope== rise/run or slope formula, m=y2-y1/x2-x1

Answer:

the answer is 2

Step-by-step explanation:

x-7-16=1+4x

add x and 4x so that your equation is now

5x+7-16=1

add 16 to 1 then cross out 16 so that your equation is

5x+7=17

subtract 7 from 17 then cross out 7 so that

5x=10

divide 5 by 10 then cross out 5 so that you ar left with

x=2

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

Explanation:

The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.

85% of $900 = 0.85*900 = 765

After the 15% discount is applied, the customer would pay $765

---------

Then after the sale, the price is marked up by 15%

This means we'll multiply by 1.15 to indicate a 15% increase

1.15*765 = 879.75

Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.

---------

Afterwards, divide the value 879.75 over the original price of $900

879.75/900 = 0.9775

Move the decimal point two spots to the right to end up with 97.75%

That percentage rounds to 98% when rounding to the nearest whole percent.

Answer:

Answer:

x = 5[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

5(x - 3[tex]\frac{3}{4}[/tex] ) = 7[tex]\frac{1}{2}[/tex]

Use distributive property

5x - 18[tex]\frac{3}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]

Add 18[tex]\frac{3}{4}[/tex] to both sides

5x = 26[tex]\frac{1}{4}[/tex]

Divide both sides by 5

x = 5[tex]\frac{1}{4}[/tex]

Answer:

[tex]\sqrt19[/tex]

Step-by-step explanation:

First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,

9^2 + b^2 = 10^2.

solve, 81 + b^2 = 100

then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].

Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.

4^2 + x^2 = 19.

Solve

16 + x^2 = 19

Subtract 16 from both sides

x^2 = 19

and finally, we take the square root of both sides

x = [tex]\sqrt19[/tex]

Answer:

they are equivalent.

Step-by-step explanation:

to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!

5/8. Each one you multiply by 3 is gonna be 15/24. 5 is a common factor of 15 and 8 is the common factor of 24
