Answer:

x = 5/2

Step-by-step explanation:

2x - 5 = 0

Add 5 to both sides;

Tara has 24 pints of green paint. She uses 1 4 of it to paint a landscape and 5 8 of it while painting a clover. She decides tha

AfilCa [17]

Answer:Tara will need to buy more 8 2/3 pint of green paint.

Step-by-step explanation:

Total amount of green paint Tara has =24 pints

Amount used to to paint a landscape =1/4 x 24= 6

Amount used To painting a clover.= 5/8 x 24= 15

Amount of paint remaining = Total paint - Amount used up in painting landscape and clover

= 24 - ( 15+ 6)

24-21

=3 pints left

Since she needs 11 2/3 pints of green paints , she will need

11 2/3 - 3 = 8 2/3 .

Therefore she will need to buy more 8 2/3 pint of green paint.

What is the slope of the line that contains the points (-1,2) and (3,3)

AlladinOne [14]

Answer:

Step-by-step explanation:

Hi there!

We are given the points (-1,2) and (3,3) and we need to find the slope.

The formula for slope calculated from two points is $\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$ , where ( $x_{1}$ , $y_{1}$ ) and ( $x_{2}$ , $y_{2}$ ) are points

since we have two points, we can substitute them into the formula, but let's label their values to avoid any confusion

$x_{1}$ =-1

$y_{1}$ =2

$x_{2}$ =3

$y_{2}$ =3

now substitute into the formula (m is the slope); remember: we have a negative number in this, so we'll be subtracting a negative.

m= $\frac{3-2}{3--1}$

simplify

m= $\frac{3-2}{3+1}$

m= $\frac{1}{4}$

so <u>B </u>is your answer

Hope this helps! :)

As John walks 16 ft towards a chimney, the angle of elevation from his eye to the top of the chimney changes from 30° to 45°. Id

levacccp [35]

ANSWER

The height is $22ft$

EXPLANATION

Let the height of the chimney be x.

$\tan(45 \degree) = \frac{x}{y}$

$1 = \frac{x}{y}$

$x = y$

$\tan(30 \degree) = \frac{x}{16+ y}$

$\frac{ \sqrt{3} }{3} = \frac{x}{16 + y}$

Cross multiply

$\sqrt{3} (16 + y) = 3x$

$16 \sqrt{3} + y \sqrt{3} = 3x$

Put

$y = x$

into the equation;

$16 \sqrt{3} + x \sqrt{3} = 3x$

Group similar terms:

$16 \sqrt{3}= 3x - x \sqrt{3}$

$16 \sqrt{3}= (3 - \sqrt{3})x$

$\frac{16 \sqrt{3} }{3 - \sqrt{3} } = x$

$x=21.856$

The height of the chimney to the nearest feet is 22
