Two cars that are 150 miles apart start driving toward each other on parallel roads. The average speed of the first car is 60 miles per hour. The average speed of the second car is 55 miles per hour. Which equation can be used to determine t, the time it takes for the two cars to pass each other?A table showing Rate in mile per hour, Time in hours, and Distance in miles. The first row shows First Car and has 60, t, and 60 t. The second row shows Second Car and has, 55, t, and 55 t.60t – 55t = 060t + 55t = 160t + 55t = 15060t – 55t = 150

How would the situation change if the interest on Emma's credit card were compounded annually
rather than monthly, and she didn't make any payments toward the balance?
Select the correct answer from each drop-down menu.
After 4 years, Emma would owe approximately $ M for her original purchase of $300.
It would take around years for her balance to increase from $300 to $450.
Answer:
$525
2.9 years
Step-by-step explanation:
This question is about financial management. It is to be noted that it would take around 2.9 years for her balance to increase from $300 to $450.
What is the calculation for the above?Note that according to the question,
After 4 years, Emma would owe about $525 for her original purchase of $300.
The equation will be:
300 * (1 + x)[tex]^{4}[/tex] = 525 (This is based on the compound interest formula_
⇒ (1+x)[tex]^{4}[/tex] = 7/4 (If we divide both sides by 300)
Hence
x = 0.1502
= 15.02%
When the balance ups from $300 to $450,
We can state that:
300 * ( 1+ 15.02%) [tex]^{y}[/tex] = 450
⇒ Hence, y = 2.9 years.

Answer:
9526
Step-by-step explanation:
simplify 3^3+27
4+3*6(4-27)^2
simplify: 4-27+ -23
4+3*6(-23)^2
since the power of 2 is even it will be a positive
4+3*6*23^2
simplify: 23^2 to 529
4+3*6*529
simplify 3*6 to 18

if you work 35.6 hours and get paid $7.85 a hour how much is that in total
Answer:
$279.46
Step-by-step explanation:
to solve this equation you have to multiply 35.6 to 7.85
35.6 * 0.05 = 1.78
35.6 * 0.8 = 28.48
35.6 * 7 = 249.2
1.78 + 28.48 + 249.2 = $279.46

A water park has pools, slides, and rides that, in total, make use of 8.7\times 10^{6}8.7×10 6 gallons of water. They plan to add a ride that would make use of an additional 4.8\times 10^{3}4.8×10 3 gallons of water. Use scientific notation to express the total gallons of water made use of in the park after the new ride is installed.
Answer:
as i said i would go with 93-51=42
Step-by-step explanation:
8.7*10.6=92.22 and 8.7*10+6=93
4.8*10.3=49.44 and 4.8*10+3=51
so i am thinking that you would add 93+51 which equals 144...
or you could try 93*51 but your gunna get 4,743
or try 93-51 which is 42
or try 93 diveded by 51 which is 1.8235294117647058
I would go with 93-51=42!

The question:
3. Two students created a list of steps for the following construction. Which student has steps in the correct order, and which does not? Explain.
The answer:
Student A is Wrong and student B is correct!
The work of the students:
You are given line AB and point C. Construct a line parallel to line AB that passes through point C.
Student A Steps:
Draw a line that intersects points B and C.
Draw a line through point C and point G.
Keep the compass at the same width, and place it on point C.
Keeping the compass at the same width, place it on point F.
Mark the intersection of the two arcs as point G.
Open the compass to the width between points D and E.
Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.
Swing an arc that crosses line BC, and label the point F.
Swing an arc that intersects the arc created from line BC at point C.
Student B steps:
Draw a line that intersects points B and C.
Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.
Keep the compass at the same width, and place it on point C.
Swing an arc that crosses line BC, and label the point F.
Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
Swing an arc that intersects the arc created from line BC at point C.
Mark the intersection of the two arcs as point G.
Draw a line through point C and point G.
Student A is wrong and Student B is correct.
How?
Direction is saying to construct a line that passes through C The last step is enough to describe that A is wrong.Its saying to swing an arc(Should be line).On the other hand Student B has done correct By passing point through C and G it satisfies our required construction.1.

How many numbers x between 1 and 100 (inclusive) have the property that x2+x3 is a perfect square?
(Please help. I'm suffering)
=========================================================
Explanation:
Factor the given expression
x^2+x^3
x^2*1+x^2*x
x^2(1+x)
x^2(x+1)
We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.
In short, we don't need to worry about the x^2 portion.
--------------------
The only thing of importance is the x+1 factor.
The x+1 must be a perfect square so that the original expression is as well.
Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}
If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".
Subtract 1 from each item to end up with this modified set
{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}
--------------------
Every item mentioned in that second set will make x^2+x^3 to be a perfect square.
For example, let's pick x = 15
x^2(x+1) = 15^2*(15+1)
x^2(x+1) = 15^2*16
x^2(x+1) = 15^2*4^2
x^2(x+1) = (15*4)^2
x^2(x+1) = 60^2
This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.
There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.
--------------------
To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.

Step-by-step explanation:
what are the x and y intercepts of the equation -2x +3y=10
Answer:
Step-by-step explanation:
To find the x-intercept, let y = 0 and solve the resulting equation for x:
-2x + 3(0) = 10, or -2x = 10. This results in x = -5; the x-intercept is (-5, 0).
To find the y-intercept, let x = 0 and solve for y: -2(0) + 3y = 10, or y = 10/3.
The y-intercept is (0, 10/3).
