62
Step-by-step explanation:
Of means multiply and is means equals
.03 * n = 1.86
Divide each side by .03
.03n/.03 = 1.86/.03
n =62
Divide the sum of 65/12 and 8/3 by their difference.
Answer:
97/4752
Step-by-step explanation:
So, this problem sounds hard but it is actually simple.
First, add
65/12 + 8/3 = 97/12
Next, subtract
65/12 - 8/3 = 33/12
Then, divide
97/12 ÷ 33/12 = 97/4752

Jasper’s new copier can produce a copy every 0.57 seconds. Jasper calculates that it will take 6.57 seconds to produce 6 copies.
What error did Jasper make?
He placed the decimal point incorrectly after he multiplied.
He multiplied the time to produce one copy by 6 instead of 12.
He added 6 and 0.57 instead of multiplying.
He found the time to produce 57 copies instead of 6.
It takes 0.57 seconds per copy and he made 6 copies.
6 + 0.57 = 6.57
He added 6 and 0.57 instead of multiplying.
The easiest way to figure this out would be to do the problem by ourselves:
0.57 · 6 = 3.42, so it will take about 3.5 seconds.
We can say that Jasper got a way different answer, so it must be something wrong with the way he multiplied. When we look through the answers and we see that rather than multiplying, Jasper added, so our answer is:
He added 6 and 0.57 instead of multiplying.
60 vehicles parked on the driveway 1/4 of them were trucks. How many trucks?
Answer:
15 trucks
Step-by-step explanation:
If there are a total of 60 vehicles, and 1/4 of them are trucks, we can multiply 60 by 1/4 to get our answer. Or because 1/4 is split into fourths, we can divide 60 by 4 to also get our answer.

Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The system solutions are as follows:
If the slope of the lines is different, then the system has a unique solution.If the slope of the lines is the same but the y-intercepts are different, then the system has no solution.If the slope and y-intercepts of the lines are the same, then the system has infinitely many solutions.If the lines are parallel that means an equal slope but different y-intercepts, then the system has no solution. Then the correct option is D.

This value is approximate.
=========================================================
Work Shown:
First we need to find angle C
A+B+C = 180
46+73+C = 180
119+C = 180
C = 180 - 119
C = 61
This is not the final answer, so answer choice B is likely a trick/trap answer.
We'll use this angle value to help find side c. Use the law of sines
c/sin(C) = b/sin(B)
c/sin(61) = (32.3)/sin(73)
c = sin(61)*(32.3)/sin(73)
c = 29.5410185554849 which is approximate
c = 29.5 which points us to choice A as the final answer.

Answer:
x = 30
b = 30
a = 90
Step-by-step explanation:
So first let's find the 'X'
we already know one angle - 30 degrees
i think you should know the straight equals 180 so we minus 180 to 30
- 180 - 30 = 150
then we know there is 2x and 3x, which is unknown so in this we actually divide 150 with 5 cause 2 + 3 = 5, to get the x value
so x = 30
____________________________________________________
so you know the progress so I will write the answers now
x = 30
b = 30
a = 90
___
so just to check the answers I will add all the numbers to equal it to 360
30 + 90 + 60 + 30 + 60 + 90 = 360
Answer:
Step-by-step explanation:
30 + 2x + 3x = 180 {Straight line angles}
30 + 5x = 180 {Combine like terms}
5x = 180 - 30 {Subtract 30 from both sides}
5x = 150
x = 150/5 {divide both sides by 5}
x = 30
30 + 3x + a = 180 {Straight line angles}
30 + 3*30 + a = 180
30 + 90 + a = 180
120 + a = 180
{Subtract 120 from both sides}
a = 180 - 120
a = 60
b + 2b + a = 180 {Straight line angles}
3b + a = 180
3b + 60 = 180
3b = 180 - 60 {Subtract 60 from both sides}
3b = 120
b = 120/3
b = 40
Determine the interval(s) on which the given function is decreasing.
Polynomial going up from the left and passing through the point negative 1 comma 0 and going to a relative maximum at the point 0 comma 5 and then going down to a relative minimum at the point 1 comma 4 and then going up to the right
A function is decreasing if, reading from left to right, we can see that the graph of the function goes down.
Here we can't see the graph, but we have a brief description.
"the graph goes up until it reaches a maximum at (0, 5), then the graph reaches a relative minimum at (1, 4), then it goes up again"
Now, the graph was going up until it reached the maximum, so at that point, the graph starts going down.
The graph will go downwards until it reaches the minimum, at that point the graph starts increasing again.
So the graph only goes down between x = 0 and x = 1.
we can conclude that the interval on which the given function is decreasing is [0, 1]

Cos of Pen = pCos of Box = bb + p = 1201.1b - 0.9p = 52Solve the system by substitution:
p = 120 - b1.1b - 0.9(120 - b) = 521.1b + 0.9b = 52 + 1082b = 160b = 160/2b = 80Find p:

How much would Carson have to pay in a month where he used 3 GB over the limit? How much would Carson have to pay in a month where he used went over by x GB?
Answer:
3 GB over: $80 x GB over: $35+$15x
Step-by-step explanation:
First, 3 GB over is 3 times 15 plus 35, which equals 80. x GB over is x times 15 plus 35, hence the answer. Hope this helps!
For using 3GB of data more, she'll be charged $80.
a. Amount charged per month = $35
Amount charged for over-usage = $15 per gb.
Therefore, when she uses 3gb more, the amount charged will be:
= $35 + ($15 × 3)
= $35 + $45.
= $80
When she uses x gb more, the amount that she'll be charged will be:
= $35 + ($15 × x)
= $35 + 15x
= 35 + 15x

Does this graph show a function? Explain how you know.
O A. Yes; there are no y values that have more than one x-valuer
O B. No, there are y-values that have more than one x-value.
O C. Yes, the graph passes the vertical line test.
O D. No, the graph fails the vertical line test. SUBMIT
Answer: D) No. The graph fails the vertical line test.
Explanation:
We are able to draw a single vertical line that passes through more than one point on the red curve. For example, we could draw a vertical line through x = 5 and have it cross the red curve at (5,4) and (5,-4).
So this is one example where the graph fails the vertical line test. It passes this test when such a thing doesn't happen. In other words, a function is only possible if any x input leads to exactly one and only one y output.
In this case, x = 5 leads to multiple outputs y = 4 and y = -4 at the same time. There are other x values which this occurs as well (any x values such that x > 1). So this is why we don't have a function.
