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?

Step-by-step explanation:

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

By dividing the figure in a rectangle and a circle, we will see that the area of the composited figure is equal to 149.25 square units.

The area will be the area of the rectangle plus the area of the semicircle.

We can see that the width of the rectangle is equal to the diameter of the semicircle, and the radius of the semicircle is 5 units, so its diameter is:

2*5 = 10 units.

Then the rectangle measures 11 units by 10 units, then its area is:

A = 10*11 = 110 square units.

In another hand, for a semicircle of radius R the area is:

A = 0.5*3.14*R^2

In this case we have R = 5, replacing that we get:

A = 0.5*3.14*5^2 = 39.25 square units.

Adding these two we get:

Area = 110 square units + 39.25 square units = 149.25 square units.

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.

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:

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.

I am not sure if this is answering your question since you don't specifically have one listed.

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.

Here , we need to find a formula for nth term of the sequence 6 , 12 , 18 , .....

Now , here if you notice carefully ,then you can notice that 12 - 6 = 6 and 18 - 12 = 6 , So the given sequence is an AP ( Arithmetic Progression ) with common difference being 6 , first term being 6 , so now as we know that :

Where , [tex]\bf a_n[/tex] is nth term of AP , [tex]\bf a[/tex] being first term while [tex]\bf d[/tex] is the common difference . So , now putting the values in above formula ;

[tex]{:\implies \quad \sf a_{n}=6+(n-1)6}[/tex]

[tex]{:\implies \quad \sf a_{n}=6+6n-6}[/tex]

Cancelling 6 will yield :

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{a_{n}=6n}}}[/tex]

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.
