The first time I did the math including 8 but we are increasing it so it will just be how much did the price increase from 8 to 18 well I know 100% of 8 is 8 so thats 100% and 25% of 8 is 2 so I added the two and 8 + 8 = 16 + 2 = 18 I added those percents 100 + 25 = 125%

spin [16.1K]

Answer:

Step-by-step explanation:

She can use a dime and a quarter to buy one package. With 3 dimes and more than 3 quarters, she can buy 3 packages this way.

She can use 2 nickels and a quarter to buy one package. With 2 nickels and the 2 remaining quarters, she can buy 1 package this way.

Mae-Ying can buy 4 packages, and will have 1 quarter left over.

_____

You can add up her money and divide by 35¢ to find the number of packages. Doing that, you get ...

5·0.25 +3·0.10 +2·0.05 = 1.25 +0.30 +0.10 = 1.65

Then 1.65/0.35 ≈ 4.71, so Mae-Ying can buy 4 packages with the money she has.

3.5 m = 350 cm

9.072 km = 9072 m

0.07 kg = 70 g

70.4 l = 70400 ml

79 m = 0.079 km

6 g = 6000 kg

5,870 m = 5.78 km

61,900 g = 61.9 kg

Could someone give me a hand?

Leokris [45]

Answer:

Step-by-step explanation:

Look at the image I attached for reference as I explain. (I only labeled the angles that are relevant to the problem)

These triangles are congruent, as shown by the first equation.

When triangles are congruent, it means that the sides and angles are the same.

We can see that angles ∠ABC and ∠DEC are corresponding, which means that they have the same value.

We don't know ∠DEC, but we have two angles in that triangle that we do know. Since the angles in a triangle add up to 180, we have this equation:

180-65-55=∠DEC

60 = ∠DEC

So now we know that ∠DEC is 60 degrees.

Since ∠ABC and ∠DEC are equal:

2x=60.

Divide both sides by 2, and we get x =30.
