Answer:

Boy's feet is closer

Step-by-step explanation:

Given that :

Distance from Surface of pool :

Girl's feet : 4/6 yards = 2/3 yards

Boy's feet : 1/6 yards

Comparing the two distances ;

2/3 = 0.6666

1/6 = 0.1666

Hence, 2/3 > 1/6

Therefore, distance between the boy's feet and the surface is lesser and hence closer than the girl's feet

Answer:

[tex]9\sqrt{2}[/tex] feet

Step-by-step explanation:

Consider the attached figure.

An isosceles triangle is a triangle in which two sides are equal.

[tex]AB=BC=9[/tex] feet

According to Pythagoras theorem,

square of hypotenuse is equal to sum of squares of other two sides.

[tex]AC^2=AB^2+BC^2\\AC^2=9^2+9^2\\AC^2=81+81\\AC^2=162\\AC=\sqrt{162}[/tex]

[tex]AC=9\sqrt{2}[/tex] feet

Answer:

Answer is 35

Step-by-step explanation:

After 15 days, 600-180=420.

After 15 days, 600-180=420.Therefore, 600 : 50

After 15 days, 600-180=420.Therefore, 600 : 50 420 : X

Let X represent the number of days.

So now, X. × 50

X. × 50 ----. ----. Or Simply 50/ 600= 1/12

X. × 50 ----. ----. Or Simply 50/ 600= 1/12 420. 600.

No u cross multiply this fraction.

Which is, X × 12= 12X

X × 12= 12X 420 × 1 = 420

U have to let X stand alone.

12X = 420

12X = 420 ------. -------

12X = 420 ------. ------- 12. 12

So now u cancel out, 12 will cancel 12 so X will stand alone.

So now 12 will cancel 420 which means 12 will go into 420, 35times.

Therefore X = 35

Meaning the hostel will feed the rest of the students for 35days.

Answer::

The answer is 3037.5

Explanation::

4.5 x 7.5 x 6 x 15 = 3037.5

Answer:

319.5in

Step-by-step explanation:

First lets calculate the area of all the rectangles

2(6in * 15in) = 180in

The 2 is because there are two rectangles with the dimensions of 6in and 15in.

7.5in * 15in = 112.5in

112.5in + 180in = 292.5

Next lets calculate the area of the triangles.

4.5in * 6in / 2 = 13.5in

13.5 + 13.5 = 27in

292.5in + 27in = 319.5in

hope this helps!

Answer:

15n = 330

Value of n(number of lawns) = 22

Step-by-step explanation:

She has already saved $85 which means the amount of money she needs left will be

=$415 - $85

= $330

Now n represents the number of lawns she needs to mow. She earns $15 per lawn, so she needs to multiply the cost of each lawn by the number of lawns (n) and equal it to the money she needs. This is how the equation will turn out.

15n = 330

To go further, divide both sides by 15 to get the number of lawns she has to mow.

[tex]\frac{15n}{15} =\frac{330}{15}[/tex]

n = 22

∴ She needs to mow 22 lawns to get the amount of money she needs.

Answer:

a = 21 - 8

Step-by-step explanation:

to determine the number of apples in each basket, first determine the total number of fruits in each basket and subtract it from the number of oranges in each basket

number of fruits in each basket = 168 / 8 = 21

a = 21 - 8

Answer:

25728

Step-by-step explanation:

Amount i would have in 3 months = simple interest + amount deposited

Simple interest = principal x time x interest rate

Principal = 25600

Interest rate = 2%

Time = 3/ 12 = 0.25

25,600 x 0.02 x 0.25 = 128

Total amount = 25,600 + 128 = 25728

Step-by-step explanation:

Total hours work: 6 hours

Hourly wages: $8.00

Kendall total amount made for babysitting: 6 x $8 = $48.00

Total amount spent on shirts: $48 x 2/5 = $19.20

Amount of money Kendall had left after purchasing the shirt:

      $48.00 - $19.20 = $28.80

Answer:

  s = (8 mi)/(24 min/(60 min/h))

Step-by-step explanation:

Let s represent Darnell's constant speed. We know that speed, distance, and time have the relationship ...

  speed = distance/time

Darnell's speed in miles per hour is ...

  s = (8 mi)/(24 min/(60 min/h)) . . . . equation representing Darnell's speed

_____

This simplifies to ...

  s = 20 mi/h

Answer:

30 yd²

Step-by-step explanation:

Hello There!

The shown figure is a trapezoid

The first thing we need to do is figure out what the formula for area of a trapezoid is

[tex]A=\frac{a+b}{2} h[/tex]

where a and b = bases and h = height

we are given all of the dimensions so all we have to do is plug in the values

a = 9

b = 6

h = 4

[tex]A = \frac{6+9}{2} 4\\6+9=15\\\frac{15}{2} =7.5\\7.5*4=30[/tex]

so we can conclude that the area of the figure is

30 yd²

~TheMathWiz

Answer:

30

Step-by-step explanation:

first you find the area of the rectangle the formula is A=wl

A=6*4=24

Then find the area of the triangle the formula is A =h b/2

A=4 3/2

6

the base is 3 because the whole bottom is 9 but the base of the square is 6 and so 9-6=3

now add them together

24+6=30

Answer:

24 houses per block!

Step-by-step explanation:

48÷2=24

Answer:

3x+4(3x−5)=25

Use the distributive property to multiply 4 by 3x−5.

3x+12x−20=25

Combine 3x and 12x to get 15x.

15x−20=25

Add 20 to both sides.

15x=25+20

Add 25 and 20 to get 45.

15x=45

Divide both sides by 15.

x= 45/15

Divide 45 by 15 to get 3.

x=3

Answer:

201.6

Step-by-step explanation:

y varies directly as x

y = kx... "k" is the constant

y = 25, x = 140

25÷140 =k × 140÷140

k = 0.17857

y = 0.17857 × x

when y = 36 what is x

36 = 0.17857 × x

x =36÷0.17857 =201.6

Step-by-step explanation:

the street and the diameter of the bike are not measured in the same units. We have to convert them to the same units

1 feet = 12 inches

157 x 12 = 1884

circumference of a circle = 2nr

2 x 3.14 x 10 = 62.8 in

Number of revolutions = 1884/62.8 = 30

Answer:

the area of a circle with a circumference of 11π feet is

A≈9.63

Answer:

m+ p+ q= 180°

m+76°+72°=180°

m+ 148=180°

m=180°-148

m=32°

Step-by-step explanation:

Answer:

68/15 miles

Step-by-step explanation:

Miles she rode on Saturday = (6x5+4) / 5 = 34/5 miles

Miles she rode on Sunday = 34/5 x 2/3 = 68/15 miles --As it is stated that she rode 2/3 of the distance of Saturday's, so simply multiple it by 2/3

Answer:

5/6 chance of getting something greater than 4

Step-by-step explanation:

Answer:

it should be C based on the p

Answer:

A.

Step-by-step explanation:

A is correct because the pizza(p) cost $6 not $2.50 and the Drinks(r) cost $2.50 not $6 so that already eliminates C and D.

And too chose between A and B is that did it need to be less than or equal too $50 (≤) .

or did it need too be more than or equal too 9p+2.5r (≥).

it needed to be less than or equal too $50 so it is  ≤
