In two similar geometric figures, the ratio of their corresponding sides is called the scale factor<span>. To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. For the problem above, we will have a scale factor of 60:24, 5:2 or 2.5. Hope this answers the question. </span>

George bought 2.5 pounds of each type of fruit shown on the sign apples $1.30/lb,grapes $1.65/lb,bananas $0.49/lb.what was the t

Stella [2.4K]

Answer:

$8.60

Step-by-step explanation:

Let’s find the cost for each item

Apples: 2.5 x 1.30 = 3.25

Grapes: 2.5 x 1.65 = 4.125

Bananas: 2.5 x 0.49 = 1.225

Now we will add all the costs which will give use our total!

3.25 + 4.125 + 1.225 = 8.6

So the answer will be $8.60

Solving a right triangle ‼️ Can someone help me find A,a and c❓ (Round to the nearest tenth)

denis23 [38]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for A

A = 180° - (90 + 48)° = 180° - 138° = 42°

----------------------------------------------------------

tan48° = $\frac{opposite}{adjacent}$ = $\frac{18}{a}$

Multiply both sides by a

a × tan48° = 18 ( divide both sides by tan48° )

a = $\frac{18}{tan48}$ ≈ 16.2 ( to the nearest tenth )

-----------------------------------------------------------

sin48° = $\frac{opposite}{hypotenuse}$ = $\frac{18}{c}$

Multiply both sides by c

c × sin48° = 18 ( divide both sides by sin48° )

c = $\frac{18}{sin48}$ ≈ 24.2 ( to the nearest tenth )
