Answer: 1/15

Step-by-step explanation: A. If 1/3 cup makes 5 rolls, you need to know how many cups make one. (1/3)/5 = 1/15 Take the number of cups for one roll and multiply it by 3. 1/15 x 3 Final Answer = 3/15

B. Take the number of cups you have divided by 1/3 (since you know how many roles this makes) (5 2/3) / (1/3) Final Answer = 17

C. Well, we already solved for this one in A, didn't we? Final Answer = 1/15

Of a triangle

arsen [322]

Complete question is attached.

Answer:

a) ED = 6.5 cm

b) BE = 14.4 cm

Step-by-step explanation:

From the triangle, we are given the following dimensions:

AB = 20 cm

BC = 5 cm

CD = 18 cm

AE = 26 cm

We are asked to find length of sides ED and BE.

a) Find length of ED.

From the triangle Let's use the equation:

$\frac{AB}{BC} = \frac{AE}{ED}$

Cross multiplying, we have:

AB * ED = AE * BC

From this equation, let's make ED subject of the formula.

$ED = \frac{AE * BC}{AB}$

Let's substitute figures,

$ED = \frac{26 * 5}{20}$

$ED = \frac{130}{20} = 6.5$

Therefore, length of ED is 6.5 cm.

b) To find length of BE, let's use the equation:

$\frac{AB}{AC} = \frac{BE}{CD}$

Cross multiplying, we have:

AB * CD = AC * BE

Let's make BE subject of the formula,

$BE = \frac{AB * CD}{AC}$

From the triangle, length AC = AB + BC.

AC = 20 + 5 = 25

Substituting figures, we have:

$BE = \frac{20 * 18}{25}$

$BE = \frac{360}{25} = 14.4$

Therefore, length Of BE is 14.4cm

What is the equation of the line that passes through (0, 3) and (7, 0)?

r-ruslan [8.4K]

The answer should be (C):y=(-3/7)x+3 because:

if you use the slope formula: (Y2-Y1)/(X2-X1) it would look like this:

(0-3)/(7-0) and the slope of the line would be -3/7

then using the slope you just found, plug it into the y=mx+b equation along with one set of coordinates to find b (the y-intercept):

y=mx+b
0=(-3/7)(7)+b
b=3

SO, overall if you put the slope (m) and the y-intercept (b) that you found together, you get the line formula of y=(-3/7)+3
