REY [17]

Answer:

$\frac{82}{10}$

Step-by-step explanation:

$1\frac{1}{5} +\frac{17}{2} -\frac{3}{2}$

→ Convert the mixed number into an improper fraction

$\frac{6}{5} +\frac{17}{2} -\frac{3}{2}$

→ Complete the takeaway operation

$\frac{6}{5} +\frac{14}{2}$

→ Make the denominators the same

$\frac{12}{10}+\frac{70}{10}$

→ Simplify

$\frac{82}{10}$

The maximum height of an Asian elephant is 9.8 feet.what mixed fraction number represents this height?

Vitek1552 [10]

9.8 / 1, but fractions don't like decimals, so 98/10
90/10 is 9, so 9 with 8/10 remaining.
8/10 can be simplified to
4/5
So it is 9 and 4/5

What is the equation of the parabola, in vertex form, with focus at (1,-4) and<br> directrix x= 3?

lilavasa [31]

Answer:

Step-by-step explanation:

1) according to the definition of parabola d(focus)=f(directrix),

2) then

$d(focus)=\sqrt{(x-1)^2+(y+4)^2} \ and \ d(directrix)=|x-3|;$

$\sqrt{(x-1)^2+(y+4)^2} =|x-3|;$

3) after evoluation the equation:

(y+4)²=-4x+8 or (y+4)²= -4(x-2);

4) correct answer is D.

What is the answer 7/10x-1/5=4

Marta_Voda [28]

<span>7/10x-1/5=4 should be written as (7/10)x - 1/5 + 4

or as 7x/10 - 1/5 = 4.

Multiply all 3 terms of the latter equation by 10 to eliminate fractions:

7x - 2 = 40

Then 7x =42, and x = 6.</span>
