20% of 55 is 11

Convert your percentage into a decimal:
$\frac{20}{100} = 0.2$

Multiply your decimal by 55:
$0.2 \times 55 = 11$

20 percent is 1/5, so divide 55 by 5, which equals 11.

Questions<br> E<br> Given EA = 8 and AT = 10<br> Find ET

xxTIMURxx [149]

Answer:

ET = 80/A^2

Step-by-step explanation:

First, isolate the variables that you need, which is E and T, using the two equations you were given.

EA = 8

E = 8/A (divide A on both sides to isolate E)

AT = 10

T = 10/A (divide A on both sides to isolate T)

Now, substitute.

ET --> (8/A) x (10/A) = 80/A^2

Answer:

The answer is "778"

Step-by-step explanation:

Given value:

$\to \mu= 711\\\\\to \sigma= 80\\\\\to P(Z >0.84) = 0.20\\\\\to z = 0.84$

The formula for z-score:

$\to x = z \times \sigma + \mu \\\\\to x = 0.84 \times 80 + 711 \\\\ \to x=67.2 +711\\\\ \to x= 778.2\\\\ \to x= 778$

Jim drove 204 miles in 4 hours. If he can keep the same pace how long will it take him to drive 918 miles

SSSSS [86.1K]

18 hours.

Proportions and stuff.

$\frac{204}{4}$ = $\frac{918}{x}$

Cross multiply,

204x = 918 * 4

204x = 3672
/204 /204
x = 18

18 hours.

Draw clearly the graph of the linear equation. y=1/2x, where x= (-4 -2, 0, 2, 4)

aniked [119]

Answer:

(in attachment)

Step-by-step explanation:

you can find the points by inputting the x-values into the equation to solve for the y-values, then connecting the plotted points to create the line.

When x=-4

y=1/2(-4)

y=-2

(-4,-2)

Repeat for all values.
