0.1 x 2 = 0.2 When you multiply 0.1 and 2, you move the decimal once because there is one decimal place.

0.1 times 3 = 0.3.

when you multiply the two numbers together, ignore the decimal. once you get the answer, move the decimal over left as many times as it was orignally.

If a ray divides an angle into two complementary angles, then the original angle is a right angle

No as complementary angles add up to whisk 180 degrees, however supplementary angle would be true for this question

Jan and Wayne went to the store to buy some groceries. Jan bought 2 cans of corn beef hash and 3 cans of creamed chipped beef fo

marin [14]

You can solve this by using the system of equations.
Jan - 4.95 = 2H + 3C
Wayne - 5.45 = 3H + 2C

Use elimination.
-3(2H + 3C = 4.95)
2(3H + 2C = 5.45)

Solve. And you'll get:
-6H + (-9C) = -14.85
6H + 4C = 10.9

Cross out -6H and 6H because they cancel out. And you're left with:
-9C = -14.85
4C = 10.9

Add -9C with 4C, and -14.85 with 10.9.
-5C = -3.95

Divide each side with -5.
C = $0.79

Now to figure out what H is, just substitute the C in one of the equations with 0.79.
5.45 = 3H + 2(0.79)
5.45 = 3H + 1.58
-1.58 -1.58
3.87 = 3H
3.87/3 = 3/3(H)
1.29 = H

Finished!

Joseph owns a hot dog stand and sells specialized hot dogs. He charges $1.50 for a plain hot dog and then an additional $0.50 fo

Lilit [14]

Hot Dog Stand

Let

C--------> total cost of the hot dog

x-------> is the number of toppings

we know that

$C=0.5x+1.5$

where

The slope of the linear equation is equal to $0.5\frac{\$}{topping}$

The y-coordinate of the y-intercept of the linear function is equal to $\$1.5$

That means -------> This is the cost of the hot dog without topping

Hamburgers Stand

Let

C--------> total cost of the hamburger

x-------> is the number of toppings

we know that

$C=0.25x+2.50$

where

The slope of the linear equation is equal to $0.25\frac{\$}{topping}$

The y-coordinate of the y-intercept of the linear function is equal to $\$2.5$

That means -------> This is the cost of the hamburger without topping

therefore

the answer is

The linear equation of the hamburger cost is equal to

$C=0.25x+2.50$

If angle 1 is 140°, then find the measure of the other angles.

Vlad [161]

<h2>Angles</h2>

<h3>If angle 1 is 140°, then find the measure of the other angles.</h3>

∠2 = 40°
∠3 = 40°
∠4 = 140°
∠5 = 140°
∠6 = 40°
∠7 = 40°
∠8 = 140°

Explanation:

The relationship between ∠1 and ∠2 are supplementary angles, so when you add up their measurements, it will become 180°. Simply subtract 180 and 140 to get the measure of ∠2. As well as ∠3, they're linear pairs. And they are also supplementary. To determine the measure of ∠6 and ∠7, notice the relationship between ∠2 and ∠6. As you noticed, it is corresponding angles. So they have the same measurement. If ∠2 = 40°, then ∠6 = 40°. As well as ∠7, because the relationship between ∠6 and ∠7 are vertical pairs. So the angle measurement of ∠7 is also 40°.

Meanwhile, the relationship between ∠1 and ∠4 are vertical pairs. It means they also have the same measurement. So ∠4 = 140°. The relationship between ∠1 and ∠5 are corresponding angles, so they also have the same measurement. If ∠1 = 140°, then ∠5 = 140°. The relationship between ∠1 and ∠8 are alternate exterior angles, and they also have the same measurement. If ∠1 = 140°, then ∠8 = 140°.
