Answer:

Do long division

Step-by-step explanation:

Put a decimal point after the 7 and add some zeros: 8 goes into 7 zero times. Put a decimal point after the zero up in the answer, and just continue with long division. 7/8 is a rational number (a fraction), so you know the division will end.

Answer:

$648\ yd$

Step-by-step explanation:

step 1

Find the circumference of the complete circle

The circumference is equal to

$C=2\pi r$

we have

$r=35\ yd$

substitute

$C=2\pi(35)$

$C=70\pi\ yd$

step 2

Find the measure of the arc length for a central angle of 280 degrees

Remember that the circumference subtends a central angle of 360 degrees

so by proportion

$\frac{70\pi}{360}=\frac{x}{280}\\ \\x=280*(70\pi )/360\\ \\x=54.44\pi\ yd$

step 3

Find the perimeter of the playground

$P=54.44\pi+45=54.44*3.14+45=215.96\ yd$

Multiply by 3

$215.96*(3)=647.87\ yd$

Round to the nearest integer

$647.87=648\ yd$

A^2(64a^2-3)/3=27-4a^2/4

frutty [35]

The answer is a = 3/4 = 0.75

First get rid of the paranthesis,
${a}^{2} (64 {a}^{2} - 3) = 64 {a}^{4} - 3 {a}^{2}$
Then set the denominators equal:
$\frac{ 256 {a}^{4} - 12 {a}^{2}}{12} = \frac{81 - 12 {a}^{2} }{12}$
Then remove the denominators and solve:
$256 {a}^{4} - 12 {a}^{2} = 81 - 12 {a}^{2}$
Eliminate -12a^2 by adding 12a^2 to both sides:
$256 {a}^{4} = 81$
Take the fourth root of them or take the square root twice:
$\sqrt[4]{256 {a}^{4} } = \sqrt[4]{81} \\ 4a = 3$
Divide both sides by 4:
$a = \frac{3}{4} = 0.75$

george is paints his fence . he paints 1/4 of the fence in 2/5 an hour . how long will it take him to the entire fence

KatRina [158]

1 and 3/5 hours since he paints 1/4 every 2/5 an hour simply times 2/5 by 4/1 and get 8/5 which is equal to 1 and 3/5 an hour
