Lisa leaves her house for a road trip and drives at a rate of 50 mph. Keisha leaves her house 1 hour later and drives along the same route at a rate of 60 mph. At any given time t, the distance traveled can be calculated using the formula d = rt, where d represents distance and r represents rate. Which system of equations can be used to find how long after Lisa departs her house she is passed by Keisha?A) d=50t
d=60t-1

B) d=50t
d=60(t-1)

C) d=50t
d=59t

D) d=50(t-1)
d=60t

The Keller family spent a total of $63.04.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

First, let's find the cost of the meal before tax and tip.

We know that the total bill, including tax, is $55.35, which is equal to 100% + 8% (the tax rate) = 108% of the original meal cost.

We can set up an equation to solve for the original meal cost (let's call it x):

x + 0.08x = 55.35

Simplifying the left-hand side:

1.08x = 55.35

Dividing both sides by 1.08:

x = 51.25

So the cost of the meal before tax and tip was $51.25.

Next, let's calculate the amount of tax they paid:

0.08x = 0.08(51.25) = 4.10

So the tax they paid was $4.10.

Now let's calculate the tip they left for the server. They left a 15% tip on the original meal cost of $51.25:

0.15(51.25) = 7.69

So the tip they left was $7.69.

Finally, to find out how much they spent in total, we add up the cost of the meal, the tax, and the tip:

51.25 + 4.10 + 7.69 = 63.04

Therefore, the Keller family spent a total of $63.04.

Answer:  The required intersection is the line 'VS'.

Step-by-step explanation:  We are given to find the intersection of the planes WZVS and plane STUV.

We know that,

If two planes intersect each other, then their intersection is a straight line.

As shown in the given figure, the point 'V' and 'S' lie on both the planes WZVS and STUV.

So, the line joining these two points, i.e., the line VS also lie on both the planes.

Therefore, the intersection of both the planes is the line 'VS'.

Thus, the required intersection is the line  'VS'.
