Answer:

Step-by-step explanation:

h = 5 ft

diameter = 2.4 ft

Radius is half of diameter

r = 2.4/2 = 1.2 ft

Now, find the volume of the tank

Volume = πr²h

             = 3.14 * 1.2 *1.2 * 5

             = 22.608 cubic ft

Time taken to fill the tank = Volume of tank ÷ volume of gas filled per minute

= 22.608 ÷ 2.3

= 9.8

= 10 minutes

Answer:

75.5 cm

Step-by-step explanation:

S = (a+b)*h/2

h = 2 * S / (a+b) = 2 * 7701 / 204 = 75.5 cm

Answer:

the cost for one cookie is $0.6(60 cents)

Step-by-step explanation:

9 divided by 15 = 0.6

Answer:

60 cents

Step-by-step explanation:

Cost of 15 cookies = $9

Cost of 1 cookie = 9/15

9/15=0.6

Answer:

379.56ft²

Step-by-step explanation:

Oh lordy why, okay we got this:

So we're going to start with the area of the square, this is easy because all of the sides are 25ft, so we just have to plug into our formula for squares (base x height):

25 x 25 = 625

Now we have to do the semicircle, remember that the formula for the area of a circle is pi x radius², we're using 3.14 for pi, so we have to find the radius (half the diameter):

25 ÷ 2 = 12.5

12.5² = 156.25

3.14 x 156.25 = 490.625‬

Normally we would stop here, but because this is only a semicircle, we have to divide by two:

490.625‬ ÷ 2 = 245.3125‬

So, now that we have our two areas, we have to subtract the semicircle from the square:

625 - 245.3125‬ = 379.6875‬

Now, I realize that his answer isn't in your cute little word bank, but that because I rounded pi, so the closest is 379.56

So, the area of the figure is 379.56ft²

if this is wrong let me know so I can fix it

hope this helps:)

Answer:

since r > 0.361

we reject H₀

Therefore, Yes, It does suggest that  there is a linear relation between student task persistence and achievement score, since r  [0.883 ] is greater than critical value for 30 [ 0.361 ]

Step-by-step explanation:

Given the data in the question;

n = 41

r = 0.883

H₀ : population correlation coefficient = 0 ( both are independent )

Hₐ : population correlation coefficient ≠ 0 ( there is a linear relation between student task persistence and achievement score )

critical value for n = 30 is 0.361

that means, for n = 41, critical value will be less than 362

now, since r > 0.361

we reject H₀

Therefore, Yes, It does suggest that  there is a linear relation between student task persistence and achievement score, since r  [0.883 ] is greater than critical value for 30 [ 0.361 ]

Answer:

20 cm is the length of third side of triangle

Step-by-step explanation:

Length of 1st side = a

Length of 2nd side = 10cm = b

Length of 3rd side = 15cm = c

So,

Perimeter of triangle = 45 cm

a+b+c = 45cm

a + 10 + 15 = 45 cm

.'. a = 45-25 cm

= 20 cm

The midline or midsegment has a length equal to half of the third side.

Therefore, the length of the third side is 45 cm × 2 = 90 cm.

Response:

Given:

The length of the midline = 45 cm

Required:

The length of the third side

Solution:

The midline is the line joining the midpoint of two sides of a triangle.

According to the midsegment theorem, the midline of a triangle is

parallel to the third side and has a length equal to half the length of the

third side.

Which gives;

The length of the mid line = [tex]\mathbf{\frac{1}{2}}[/tex] × The length of the third side

Let x represent the length of third side, we have;

45 = [tex]\frac{1}{2}[/tex] × x

Which gives;

The length of the third side, x = 2 × 45 cm = 90 cm

Answer:

x = 10

Step-by-step explanation:

Measure of the angle with it's vertex inside a circle = ½(sum of intercepted arcs)

Thus,

m<E = ½(HL + GF)

Substitute

60 = ½(55 + 5x + 15)

Multiply both sides by 2

2(60) = 55 + 5x + 15

120 = 5x + 70

120 - 70 = 5x

50 = 5x

50/5 = x

10 = x

x = 10

I took the quiz

Answer:Lets say 60 is rounded to 60. So 60 is half of 120 , which means that the answer is a little bit more than 50% since 50x2=100%

So 50 plus the 5 we took away from the 60 in the beginning is 55%

I think your answer is 55%

Step-by-step explanation:

Your answer is 55%

The percentage of 65 out of 120 will be 54.167%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The whole numbers are 65 and 120.

Then the percentage is written as,

P = (65 / 120) x 100

P = 0.54167 x 100

P = 54.167%

The percentage of 65 out of 120 will be 54.167%.

Answer:

The final cost of the pants is $ 12.

Step-by-step explanation:

Given that at a store that is closing the pants normally cost $ 60.00 but it is discounted 75%, and they are also taking an additional 20% off, to determine what is the final price for the pants, the following calculation must be performed:

100 - 20 = 80

(60 - (60 x 0.75)) x 0.80 = X

(60 - 45) x 0.80 = X

15 x 0.80 = X

12 = X

Thus, the final cost of the pants is $ 12.
