3 yards = $7.47
1 yard = $(7.47 ÷ 3) = $2.29
2 yards = $ (2.29 × 2) = $5.58
$ (7.47 + 5.58) = $ 13.05

You divide 7.47 by 3. Which is 2.49
Then you multiply 2.49 by 2 which is 4.98
The two extra yards of fabric would cost $4.98

What is the slope-intercept form of a line that contains the point (0,3) and a slope=-2
katen-ka-za [31]

Answer:

C. y = -2x + 3

Step-by-step explanation:

The equation of a line in slope-intercept form is given as y = mx + b.

m = slope, while b = y-intercept.

We already know that the slope, m, = -2.

We are given a point also as (0, 3). This means, at x = 0, y = 3.

Therefore, the y-intercept, b, = 3, because, the line would intercept the y-axis of the graph at y = 3, and at that point, x = 0.

Thus,

Slope (m) = -2,

y-intercept (b) = 3

Plug these values into y = mx + b

✅The equation of the line in slope-intercept form would be:

y = -2x + 3

If Haley's ant farm doubles in population, she will have 122 more ants in her farm than Nate does. Haley's ant farm currently ha
xxMikexx [17]

Answer:

238

Step-by-step explanation:

Start with Raven's ants since hers is the one that everyone else's is based off of.  

Raven = 208

Haley has half of that plus 76, so

Haley = (208/2) + 76

Haley = 180

If Haley's farm doubles in population, she would have 360 ants.  That number is equal to Nate's number + 122.  We have an equation of sorts there to solve for Nate's ants:

180(2) = N + 122 so

360 = N + 122 and

N = 238

Nate has 238 ants in his farm.

The prism shown has a volume of 35 cm.
Vesna [10]

Answer:

1.25cm

Step-by-step explanation:

<em>Complete question:</em>

The prism has a volume of 35 cm cubed  workout h, the height of the triangular cross section

<em>length=7cm</em>

<em>width = 4cm</em>

<em></em>

The volume of the prism is expressed as;

Volume = Base Area * Height

Given

Volume of the prism = 35cm^3

Base Area = length * width

Base Area =  7cm * 4cm

Base Area = 28cm^2

Substitute the given values into the formula

35 = 28* Height

Cross multiply

35 = 28 * Height

35 = 28 Height

Height = 35/28

Height = 1.25cm

Hence the height of the triangular cross section is 1.25cm
