Answer:

-60 3/4m

Step-by-step explanation:

The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.

-50-10=-60

-(1/4)-(1/2)= (1/4)+(1/2)

(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.

=6/8 (simplifies down to 3/4)

The functions q and r are defined as follows

kolezko [41]

Answer:

Step-by-step explanation:

So we have the two functions:

$g(x)=-2x-2\text{ and } r(x)=x^2-2$

And we want to find the value of r(g(4)).

To do so, first find the value of g(4):

$g(x)=-2x-2\\g(4)=-2(4)-2\\$

Multiply:

$g(4)=(-8)-2$

Subtract:

$g(4)=-10$

Now, substitute this into r(g(4)):

$r(g(4))\\=r(-10)$

And substitute this value into r(x):

$r(-10)=(-10)^2-2$

Square:

$r(-10)=100-2$

Subtract:

$r(-10)=98$

Therefore:

$r(-10)=r(g(4))=98$

What is the simplified form of 8b^3c^ 2a + 4b^3c^2?

stiv31 [10]

$8b^{3} c^2+4b^{3} c^2$
$= (8+4) b^{3} c^2$
$=12 b^{3} c^2$

Be carefully, normally there is no a in your expression. I think you made a mistake.

Hope this helps !

3/4+(1/4-1/6)= show work adding and subtracting fractions

Fittoniya [83]

Answer:

5/6

Step-by-step explanation:

Step 1: Make all fractions have same denominator: 24

3/4 * 6/6 = 18/24

1/4 * 6/6 = 6/24

1/6 * 4/4 = 4/24

Step 2: Plug in the new fractions into the old place

3/4 + (1/4 - 1/6)

18/24 + (6/24 - 4/24)

Step 3: Solve inside parenthesis

18/24 + (6/24 - 4/24)

18/24 + 2/24

Step 4: Add

18/24 + 2/24

20/24

Step 5: Simplify

20/24

10/12

5/6

Answer: 5/6
