In a class of 30 children there are g,girls what fraction of the class are boys

Answer:

Step-by-step explanation:

Discriminant = b² - 4ac

a = 3 ; b = 24  and c = 48

Discriminant = 24² - 4*3*49

                     = 576 - 576

                      = 0

As discriminant is 0, there is only 1 real root.

Answer:

188 kids in intermediate, 100 juniors, and 13 children that attend primary school.

Step-by-step explanation:

K there are 300 kids.

5/8 are intermediate, so 5/8 * 300 = 187.5, you can't have half a kid, so we can round to 188 kids are intermediates.

1/3 are juniors, so 1/3 * 300 = 100 are juniors.

The rest are primary:

(1)-(5/8 + 1/3)= 1/24

Thus, 1/24 are primary students, so 1/24 * 300 = 12.5 and again we will round up to 13 children in primary classes.

Answer:

She picked up her camera at -25ft

Step-by-step explanation:

Given

[tex]Initial\ Position = -30ft[/tex]

Required

Determine the position she retrieved her camera

The position where she dropped her camera is given as:

[tex]Position = -10ft[/tex]

She swim down 15ft;

So, the nee position is

[tex]New\ Position = -10ft - 15ft[/tex]

[tex]New\ Position = -25ft[/tex]

Hence; She picked up her camera at -25ft

Note that: Negative signs represent that she is below the sea level

Answer:

C

Step-by-step explanation:

Hilary was scuba diving. She was 30 feet below the surface when she swam toward the dive platform. She dropped her camera when she was 10 feet from the surface and had to swim down 15 feet to get it. At what elevation did Hilary retrieve her camera?

-25feet

40/5= 8  8 is 1% of the total people, 1% x 100 = 100%

8 x 100 = 800 people

The answer to this question would be: The newspaper has Eight hundred  readers.

Part = Percent x Whole

40 = 5% x 800

Do the equation above to make sure your correct( it is) and if it doesn't come back to 40 then your math is incorrect and you have the incorrect answer

Do that with all math that your trying to find the whole for, its a helpful thing.

Answer:

NM = [tex]\sf \sqrt{70}[/tex]

Step-by-step explanation:

Let NM = y

If KL is twice the length of NM, then KL = 2y

Given:

As ΔKLN ~ ΔNOM

   KL : KM = NO : NM

[tex]\sf \implies 2y : 20 = 7 : y[/tex]

[tex]\sf \implies \dfrac{2y}{20}=\dfrac{7}{y}[/tex]

[tex]\sf \implies 2y \cdot y=7 \cdot 20[/tex]

[tex]\sf \implies 2y^2=140[/tex]

[tex]\sf \implies y^2=70[/tex]

[tex]\sf \implies y=\sqrt{70}[/tex]

As NM = y, then NM = [tex]\sf \sqrt{70}[/tex]

Answer:

NM = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

Δ NMO and Δ KML are similar ( by the AA postulate )

Then the ratios of corresponding sides are in proportion, that is

[tex]\frac{NM}{KM}[/tex] = [tex]\frac{NO}{KL}[/tex] ( substitute values, noting KL = 2NM )

[tex]\frac{KM}{29}[/tex] = [tex]\frac{7}{2NM}[/tex] ( cross- multiply )

2 NM² = 140 ( divide both sides by 2 )

NM² = 70 ( take the square root of both sides )

NM = [tex]\sqrt{70}[/tex]

The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is  12.5 square feet.

Side of each cube = 10 inches

Number of cubes =3

As we know The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes will be the total surface area of all 3 boxes.

The total surface area of a cube with side a is 6a².

So, the total surface area of a cube with a side of 10 inches will be 6*10² = 6*100 = 600 square feet.

So, the total surface area of 3 cubes with a side of 10 inches will be 600*3 = 1800 square inches.

As we know that 1 square inch = 0.00694444 square feet

So, 1800 square inches = 1800*0.00694444 = 12.5 square feet.

Therefore, the minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is  12.5 square feet.

Answer:

2:00 PM

Step-by-step explanation:

I figured out that the car is going 40 mph seeing as how it went 20 miles in 30 minutes.

I used this and found out how many hours it would take to get to 200 miles at this rate:

200/40 = 5

I divided 40 by 200 as 200 is the end goal and the car is going 40 mph.

The 5 is 5 hours, so I added 9 and 5 to get 14 which is 2:00 PM

When you add 2 of the sides together, they are always greater than the other

Answer:

(x-6)(x-4) = 0

Step-by-step explanation:

Subtract 5 from both sides to make the equation equal to 0. You will get the equation x2-10x+24=0. Now think of two numbers that multiply to get 24 but add to get -10. These numbers are -6 and -4. The factors of x2 are x and x which multiply to get x2.  Now put two linear factors into parathesis to get (x-6)(x-4) = 0.
