2.75 x 100 / .20 = 13.75
double check
$13.75 x 0.25 = $2.75
so answer
The bill was $13.75 <span>for lunch before the tip added</span>
Answer:
KL ≈ 1.94
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos48° = 
= 
= 
( multiply both sides by KL )
KL × cos48° = 1.3 ( divide both sides by cos48° )
KL = 
≈ 1.94 ( to the nearest hundredth )
I think se cuz it still has sunlight but it’s not too close
Answer: she invested $2500 at the rate of 10%.
she invested $1500 at the rate of 6%.
Step-by-step explanation:
Lisa invests $x in bond A and $y in bond B.
Lisa invests $4,000 in two types of bonds, bond A and bond B. This means that
x + y = 4000
Bond A offers a 10% return, and bond B offers a 6% return. Therefore,
Interest on bond A is 0.1x
Interest on bond B is 0.06y
Her total return on the investment is $340. It means that
0.1x + 0.06y = 340
Therefore, The system of linear equations defining the situation is
x + y = 4000
0.1x + 0.06y = 340 - - - - - - - - - - -1
Substituting x = 4000 - y into equation 1, it becomes
0.1(4000 - y) + 0.06y = 340
400 - 0.1y + 0.06y = 340
- 0.1y + 0.06y = 340 - 400
- 0.04y = - 60
y = - 60/ - 0.04
y = 1500
x = 4000 - 1500
x = 2500
In order to find the distance covered in 1 minute, we need to divide distance covered 2 1/6 miles by 20 minutes.We are given : Ariel swims 2 1/6 miles in every 1/3 hour.
Let us convert 1/3 hour into minutes.
There are 60 minutes in an hour.
Therefore, 1/3 hours = 60 × 1/3 = 20 minutes.
So, we could say, "Ariel swims 2 1/6 miles in every 20 minutes".
2 1/6÷ 20 = 13/6 ÷ 20.
Let us convert division sign into multiplication and flip 20 to 1/20.
We get
<h3>13/6 × 1/20 = 13/120 miles in 1 minute.</h3><h3>In decimal 0.11 mile in 1 minute.</h3>
