Change the percent to a decimal. 0.4% =

2 answers:

0.4% = 0.4 / 100

When dividing by 100, since 100 has 2 zeros, we shift the decimal point in 0.4 to places to the left.

0.4 / 100 = 0.004

Hope this explains it.

Find the angle measures of a triangle if the first angle is thirty-one degrees more than the second, and the third is five degre

MAVERICK [17]

Answer:

23°, 54°, 103°

Step-by-step explanation:

let the2nd angle = x

1st angle = x + 31

3rd angle = 2(x + 31) - 5 = 2x + 62 - 5 = 2x + 57

Sum the 3 angles and equate to 180

x + 31 + x + 2x + 57 = 180 , that is

4x + 88 = 180 ( subtract 88 from both sides )

4x = 92 ( divide both sides by 4 )

x = 23

Then

1st angle = x + 31 = 23 + 31 = 54°

2nd angle = x = 23°

3rd angle = 2x + 57 = 2(23) + 57 = 46 + 57 = 103°

You buy a brand new wax candle that stands 6 inches tall. Knowing that the rate at which the wax melts is approximately 1/100 of

ipn [44]

Answer:

y=-1/100x+6 or y=-1x+600

Step-by-step explanation:

6 inches is the Y intercept (600,0) if measuring by 1/100 or (6,0)

Since the wax is melting, the slope is going to be negative

y=mx+6 or y=mx+600 either is fine and would yield the same results

y=-.01x+6, y=1/100x+6 or y=-1x+600

To explainn why 6 and 600 are both fine, 6 is measuring with full inches while the 600 is measuring with .01 inches. One graph will be full numbers while the other will be decimals.

Answer: 96 green pens sold

Step-by-step explanation:

Black = 3 pens

Red = 5 pens

Green = 6 pens

Black = 7 packs

Red = 2 packs

Green = 4 packs

Black = 3 x 7 = 21 total pens

Red = 5 x 2 = 10 total pens

Green = 6 x 4 = 24 total pens

Total units for total pens = 21 + 10 + 24 = 55u

55u = 220

1u = 220/55

= 4

24u = 4 x 24

= 96 green pens sold

96 green pens were sold.

Solve the equation for y.<br><br> 6y+x=8

iVinArrow [24]

Answer:

The correct answer is $\bold{y = -\frac{1}{6}x+\frac{4}{3}}$ .

Step-by-step explanation:

We want to solve for y in the given equation. We can do this by rearranging the equation and using operational techniques to simplify.

$6y + x = 8 \ $\tex Subtract x from both sides of the equation.$

$6y + x - x = 8 - x \ $\tex Carry out the operation.$

$6y = 8 - x \ $\tex Rearrange so the equation lists the variables first and the constants second.$

$6y = -x + 8 \ $\tex Create a coefficient for the x-variable (this is -1).$

$6y = -1x + 8 \ $\tex Divide by 6 on both sides of the equation in order to isolate the y-variable.$

$\frac{6y}{6}=\frac{-1x}{6} + \frac{8}{6} \ $\tex Carry out this operation by simplifying the fractions and dividing out the operations accordingly.$

$y = -\frac{1}{6}x+\frac{4}{3} \ $\tex Be sure to verify that all fractions and terms are simplified as far as they can be and that the equation is written in proper syntax.$

Because we have the <em>y</em>-variable isolated from the rest of the equation, we are done!
