Answer:

1. $0.24

2. 89.2 miles

Step-by-step explanation:

To get the unit price, divide the total price by the amount that was purchased.

1. 3.12/13 = $0.24

For the second one, get the distance traveled per hour first then multiply by 8.

22.3 / 2 = 11.15

11.15 x 8 = 89.2

Can someone help with this. Heads up it's ratios

ohaa [14]

Answer:

<em>The median side measures 92 yards</em>

Step-by-step explanation:

Let's call x, y, and z the measures of the sides of the triangle.

The ratios between them are:

$\displaystyle \frac{x}{y}=\frac{4}{7}$

$\displaystyle \frac{x}{z}=\frac{4}{2}=2$

The first ratio gives the relation:

$\displaystyle y=\frac{7x}{4}$

The second ratio can be solved for z:

$\displaystyle z=\frac{x}{2}$

Since the perimeter is 299 yards:

$x+y+z=299$

Substituting the above relations:

$\displaystyle x+\frac{7x}{4}+\frac{x}{2}=299$

Multiplying by 4:

$4x + 7x+2x=1196$

Joining like terms:

$13x=1196$

Dividing by 13:

$x=1196/13$

x=92

Now calculate y:

$\displaystyle y=\frac{7\cdot 92}{4}$

y = 161

$\displaystyle z=\frac{92}{2}$

z=46

The median side measures 92 yards

Hellen used a coupon she received in the mail at a local boutique that decreased her purchase of $85.20 by $12.78. Her sister us

Over [174]

Answer:

y = 12665 (100⁻¹) + b

Step-by-step explanation:

To model this relationship, you're to write the equation of a line; in the form

y = mx + b

Now let y represent the full coupon value,

mx represent the amount spent by Hellen and her sister

and b, the change that's left on the coupon.

So, the summary of Hellen's transaction is:

$85.2 became $(85.2 - 12.78) which is = $72.42

The summary of her sister's transaction is:

$63.8 became $(63.8 - 9.57) which is = $54.23

So y - (72.42 + 54.23) = b

y - 126.65 = b

y = 126.65 + b

Separating m from x in mx, you have

y = 12665 x 1/100 + b

y = 12665 (100⁻¹) + b

Where m = 12,665 and x = 100⁻¹
