Answer:
- side lengths are not proportional
- 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.
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
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.
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
Answer:
12:30 a.m.
Step-by-step explanation:
You can automatically add 5 to the 7, 5 + 7 = 12. Then add 30 to the minuets. 00 + 30 = 30.
So, your answer is 12:30.
Hope this helps!!
