9514 1404 393

Answer:

  43.70 ft

Step-by-step explanation:

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides. The correct computation is ...

  Hypotenuse is √(7² +7²) = √(49 +49) = √98 = 7√2

  Perimeter of pentagon is ...

     7 +7√2 +7√2 +7√2 +7 =

     7 +21√2 +7 =

     14 +21√2 ≈ 14 +29.70 =

     Perimeter is approximately 43.70 ft.

Answer:

-4=w

Step-by-step explanation:

-79=7w+12w-3

-79=19w-3

-79+3=19w-3+3

-76=19w

-76÷19=19w÷19

-4=w

Answer:

w = -4.

Step-by-step explanation:

-79 = 7w + 3(4w - 1)

7w + 12w - 3 = -79

19w = -76

w = -4.

Answer:

143 degrees

Step-by-step explanation:

The shape is a hexagon therefore the total angle will be 720 degrees.

The sum of the total angle of the shape is 434 degrees

So to get the answer the equation is:

434 + x + x = 720 degrees

So x =  143 degrees.

10x^3+16

Step-by-step explanation:

Hope this helps

90 miles + 120 miles = 210 total miles

1.5 hours + 3 hours = 4.5 total hours.

Average speed = total distance /  total time

Average speed = 210 miles / 4.5 hours = 46 2/3 miles per hour

The total average speed for Oliver is 42 miles per hour

Given the following data:

To find the total average speed:

First of all, we would determine the total distance and total speed:

[tex]Total \; distance = Distance\;A + Distance\;B\\\\Total \; distance = 90+120\\\\Total \; distance = 210\;miles[/tex]

[tex]Total \; time = Time\;A + Time\;B\\\\Total \; distance = 1.5+3\\\\Total \; distance = 4.5\;hours[/tex]

Mathematically, the average speed is given by the formula:

[tex]Average\;speed = \frac{Total\;distance}{Total\;time}[/tex]

Substituting the parameters into the formula, we have;

[tex]Average\;speed = \frac{210}{4.5}[/tex]

Average speed = 42 miles per hour.

Answer:

C.)42.3

Step-by-step explanation:

If it's difficult to do subtraction with negatives, switch them to positive and subtract 14.5 from 56.8. In order to get a lesser negative number(negatives closer to -1 are greater), you have to add a positive number. My math teacher taught me this simple but effective method. This method is used for multiplication and division but it helps:

(Hate=Negative and Love=Positive)

If you hate to hate, you love.(neg. x neg=pos.)

If you hate to love, you hate(neg. x pos.=neg.)

If you love to love, you love(pos. x pos.=pos.)

If you love to hate, you hate(pos. x neg.=neg.)

Answer:

-14 Mexican pesos means you have a debt of $0.67 at today's exchange rates.

Step-by-step explanation:

Answer:

English: 45/50 = 0.9 = 90%

Music: 45%

Art: 25/40 = 0.625 = about 63% (if you round up)

Math: 85%

As you can see: English - highest | Music - lowest

Alice got her highest score in Maths, and her lowest score in Music.

To find out which subject Alice got her highest and lowest scores in, let's compare the scores in each subject.

English: 45 out of 50 = 45/50 = 0.9 (90%)

Music: 45 % = 45/100 = 0.45

Art: 25 out of 40 = 25/40 = 0.625 (62.5%)

Maths: 85 % = 85/100 = 0.85

Now, we can see that the highest score is in Maths (85%) and the lowest score is in Music (45%).

So, Alice got her highest score in Maths, and her lowest score in Music.

Let the two angles be 3x and 7x.

Supplementary angles add up to 180 degrees.

Therefore:

3x + 7x = 180

10x = 180

x = 18

3x = 3 * 18 = 54

7x = 7 * 18 = 126

Answer:

The two angles are 54 degrees and 126 degrees.

Answer:

Step-by-step explanation:

Every possible value of y will have an x value of x = - 2 associated with it. For example (-2, 58) is also on this vertical line. A line with more than 1 y value associated with x means the line you get is not a function.

The equation you want is x = - 2

y = x + 4

2x + y = 1 _______(1)

-x + y = 4_______(2)

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

[tex]2x + y = 1 \\ 2( - 1) + y = 1 \\ - 2 + y = 1 \\ y = 1 + 2 \\ y = 3 \\ [/tex]

Answer:

72

Step-by-step explanation:

I like to work backward with problems like these. I'll start out with 40. Then it says that his dog ate half of this number. Instead of dividing by 2, I'll have to multiply by two since I'm working backward.

So, now I have 80, the number of cards he had before his dog ate half of the collection. We also see that he bought 8 new Pokemon cards and added these two his collection. Instead of adding 8, I'll subtract 8 from 80, giving me 72. So, this is his original amount.

If I take this number and go back through the scenario, I can check my work.

72 + 8 = 80, 80/2 = 40
