Triangle A has side lengths 3, 4, and 5. Triangle B has side lengths 6, 7, and 8.
Ilya [14]

9514 1404 393

Answer:

  1. side lengths are not proportional
  2. 6, 8, 10

Step-by-step explanation:

1. The triangles are not similar because the ratios of side lengths are not the same:

  3 : 4 : 5 ≠ 6 : 7 : 8

__

2. We can make the ratios be the same by multiplying the side lengths by a common value, such as 2:

  3 : 4 : 5 = 6 : 8 : 10

If triangle B had side lengths of 6, 8, 10, then it would be similar to triangle A.

Angel lives in Florida, which has a sales tax of 6%. He just bought some word-
slava [35]

Answer:

Option B

$65.4

Step-by-step explanation:

Imposing 6% tax on the full price would mean the final amount that should be paid will be equal to 106% of the full price, also expressed as 1.06 and this is equivalent to 1.06*90=$95.4.

However, since there's a coupon then the payment will be less the value of coupon. Therefore, final payable amount will be 95.4-30=$65.4

On their way up the hill, Jack and Jill were stopped by their parents. It seems the two of them were trying to skip out on some
Katarina [22]

Answer:

77.14 minutes.

Step-by-step explanation:

Jack's time = 3 hours

Jill's time = 2.25 hours = 2 1/4 = 9/4 hours

Combined time = x

Rates :

Jack = 1/3 ; jill = 1 / 2.25 = 1 / 9/4 = 4 /9

Combined rate = 1/x

Setting up the equation :

1/3 + 4/9 = 1/x

Lcm of 3 and 9 = 9

(3 + 4) / 9 = 1/x

7/9 = 1/x

Cross multiply :

7x = 9

x = 9/7 hours

x = (9/7)* 60

x = 77.14 minutes

Combined time = 77.14 minutes.

Find the distance between the two points. Enter the number that goes beneath the radical symbol. (PICTURE ABOVE]​
Dmitrij [34]

Answer:

50

Step-by-step explanation:

To do this we know that a^2+b^2 = x^2

for b:

The distance between -1 and 4 is 5. we will use 5^2

for a:

The distance between -3 and 2 is also 5. we we use 5^2

put into the formula

5^2+5^2=c^2

25+25=c^2

50=c^2

so the square root of 50 is the distance between the points
