A circular running track is 1/4 mile long. Elena runs on this track, completing each lap in 1/20 of an hour. What is Elena's running speed?

Answer: I comment you and you never text back so you never give me that 15(1.055)^x the x it should have a number to solve it if not it can’t solve it let just said you want to solve 15(1.055)^x but the x= 4 here a picture

Answer:

Start at -11 on the number line and move 7 to the left.

Answer:

area of trapezium=1/2 ×20(38+18)=560cm²

Answer:

C. 448

Step-by-step explanation:

Since 38-18=20, you divide by 10 to find the base of the two triangles on the side. The height of the triangle is 16 and the formula is basexheightx1/2.

10x16x0.5=80

You then multiply that by two because there are two triangles

80x2=160

You then have to find the rectangle in the center, which is 16x18=288 cm

Then we add it all up

160+288=448

Answer:

24

Step-by-step explanation:

4 x 2 = 8

8 x 3 = 24

24 area

Answer:

340 feet

Step-by-step explanation:

Well if it is a perfect rectangle we can use the Pythagorean theorem to find the diagonal, which is a^2 + b^2 = c^2. So a=300, b=160, if we square them and add them it'll be 115600, and the square root of that is 340. So the diagonal is 340.

If you need a better explanation on the Pythagorean theorem let me know in the comments.

Answer:

Yep!

Step-by-step explanation:

I'm not 100% sure if your first one is correct, but I know the second one is! Great job :)

856 because it goes back to the number it starts with

Answer:

The first 1 should go in the first box.

The second option should go in the second.

The last one should go in the third box.

Answer:

area of triangle AED=1/2xAExDE

Step-by-step explanation:

Answer:

8 feet.

Step-by-step explanation:

If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio

[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.

Answer:

119.4°

Step-by-step explanation:

The answer is 119.4° because supplementary means that the angles add to 180°, and since 180-60.6 is 119.4, that is the answer.  

Sorry if I'm wrong but I hope this helps!  Have a great day/night!

Answer:

119.4 and the little degree sign (119.4 degrees)

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees.

180-60.6=119.4 degrees

Answer:

Answer: 2976 is the answer

Answer:

144ft^2

Step-by-step explanation:

Two shapes in this figure, trapezium and rectangle.

Trapezium area formula: 1/2 x (sum of bases) x Height

Rectangle area formula: length x breadth

Figure area:

Trapezium area: 1/2 x sum of bases x height

Trapezium area: 1/2 x (5+12.4) x 8

Trapezium area: 1/2 x 17.4 x 8

Trapezium area: 69.6

Rectangle area: length x breadth

Rectangle area: 12.4 x 6

Rectangle area: 74.4

Area of complete figure: Area of trapezium + Area of rectangle

Area of complete figure: 69.6 + 74.4

Area of complete figure: 144ft^2

Hope it helps you!!!!

Answer:

17 sorry

Step-by-step explanation:

Answer:

The answer to the problem is 5

Step-by-step explanation:

The sum of twice a number y and 5 is at most 15" can be translated mathematically into the following inequality:

2y + 5 ≤ 15 since the sum, 2y + 5, is at most 15 but could be less than 15.

To solve this inequality for n, proceed as follows:

First, subtract 5 from both sides of the inequality as you would in solving an equation:

2y + 5 - 5 ≤ 15 - 5

2y + 0 ≤ 10

2y ≤ 10

Now, to finally solve the inequality for the variable y, divide both sides of the inequality by 2 as you would in solving an equation:

(2y)/2 ≤ 10/2

(2/2)y ≤ 10/2

(1)y ≤ 5

n ≤ 5 which is all real number less than or equal to 5.

Test Values (y = -1/2, 0, 3, 5, and n = 7):

For y = -1/2:

2y + 5 ≤ 15

2(-1/2) + 5 ≤ 15

-1 + 5 ≤ 15

-4 ≤ 15 (TRUE)

For y = 0:

2y + 5 ≤ 15

2(0) + 5 ≤ 15

0 + 5 ≤ 15

5 ≤ 15 (TRUE)

For y = 3:

2y + 5 ≤ 15

2(3) + 5 ≤ 15

6 + 5 ≤ 15

11 ≤ 15 (TRUE)

For y = 5:

2y + 5 ≤ 15

2(5) + 5 ≤ 15

10 + 5 ≤ 15

15 ≤ 15 (TRUE)

For y = 7:

2y + 5 ≤ 15

2(7) + 5 ≤ 15

14 + 5 ≤ 15

19 ≤ 15 (FALSE)

Therefore, the possible values for y which will make the relevant inequality, 2n + 5 ≤ 15, a true statement are:

{y | y is a real number and y ≤ 5}

Answer: 36.4 miles per gallon!

Step-by-step explanation: To get your answer....divide the y (miles driven) by x (gallons used). Each divided gives you the answer of 36.4 which is the constant of proportionality between the number of miles driven and the number of gallons used.

For example: 691.6 divided by 19= 36.4

                       1528.8 divided by 42=36.4

                        1638 divided by 45=36.4

Answer:

Lacey and Rick will owe $ 7662.88  in prorated expenses

Step-by-step explanation:

The number of days till june 27 us

Jan 31 +  Feb 28   + March 31  + April 30  +  May 31  + June 26 =177 days

In a year we have 365 days

The owner has paid tax for 177 days

Now  Lacey and Rick have to pay tax for  =365 -177 days  = 188 days

Now  for one day tax amount will be

=

= 40.76

Now the tax amount for 188 days is

=

= 7662.88
