how many kilometers could 217 km red car travel in 12 hours write an equation to show your work
Answer:
The required equation is: [tex]217\times 12=2,604[/tex]
The red car can travel 2,604 Km in 12 hours.
Step-by-step explanation:
Consider the provided information.
It is given that the speed of red car is 217 km\hr
We need to write an equation and find how many kilometers could red car travel in 12 hours.
The required equation is: [tex]217\times 12=2,604[/tex]
Hence, the red car can travel 2,604 Km in 12 hours.
A 25-foot long ladder is propped against a wall at an angle of 18° with the wall. How high up the wall does the ladder reach? Round the answer to the nearest tenth of a foot. 13.8 ft 23.8 ft 26.3 ft 80.9 ft
Answer:
B) 23,.8 feet
Step-by-step explanation:
It forms a right triangle.
We use the trigonometric ratio of cos to find the answer.
cos = adjacent /Hypotenuse
Here hypotenuse is the length of the ladder and adjacent side represent the ladder toughs the wall from the ground.
cos 18 = adjacent / 25
adjacent = 25*cos18
adjacent = 23.8 feet
Answer: B) 23,.8 feet
Hope this will helpful.
Thank you.
Answer:
B) 23.8 ft

A line passes through the points (6,5) and (2,2) . Select all that describe this line.
1. y − 5 = 3/4 (x − 6)
2. y − 5 = −4/3 (x − 2)
3. y − 2 = −3/4 (x − 6)
4. y − 2 = 3/4 (x − 2)
The equations that describe the line passing through the points (6,5) and (2,2) are: [tex]1. y-5=\frac{3}{4}(x-6)$\\2. $y-2=\frac{3}{4}(x-2)$[/tex]
To determine which of these equations describe the line passing through the points (6,5) and (2,2), we can use the point-slope form of a linear equation:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line, and [tex]\left(x_1, y_1\right)[/tex] is one of the given points.
Let's find the slope using the two points:
[tex]\begin{aligned}& m=\frac{y_2-y_1}{x_2-x_1} \\& m=\frac{2-5}{2-6}=\frac{-3}{-4}=\frac{3}{4}\end{aligned}[/tex]
So, the slope of the line passing through these points is m=3/4
Now, let's plug in one of the given points into the point-slope form to check which equations match:
[tex]y-5=\frac{3}{4}(x-6)\\\text{If we plug in the point (6,5)} :\\& 5-5=\frac{3}{4}(6-6) \\& 0=0\end{aligned}$$[/tex]
This equation holds true for the point (6,5).
[tex]y-5=-\frac{4}{3}(x-2)\\\\text{If we plug in the point (2,2)} :\\2-5=-\frac{4}{3}(2-2) \\& -3=0\end{aligned}$$[/tex]
This equation does not hold true for the point (2,2).
[tex]y-2=-\frac{3}{4}(x-6)\\\text{If we plug in the point (6,5)} :\\& 5-2=-\frac{3}{4}(6-6) \\& 3=0\end{aligned}$$[/tex]
This equation does not hold true for the point (6,5).
[tex]y-2=\frac{3}{4}(x-2)\\\text{If we plug in the point (2,2)} :\\& 2-2=\frac{3}{4}(2-2) \\& 0=0\end{aligned}$$[/tex]
This equation holds true for the point (2,2).
So, the equations that describe the line passing through the points (6,5) and (2,2) are:
[tex]1. y-5=\frac{3}{4}(x-6)$\\2. $y-2=\frac{3}{4}(x-2)$[/tex]

Solve 24 - 3 x = -27.
Answer:
17
Step-by-step explanation:
Given,
24 - 3 x = -27.
24+27 = 3[tex]x[/tex]
3[tex]x[/tex] = 51
[tex]x[/tex] = [tex]\frac{51}{3}[/tex]
[tex]x[/tex] = 17
3. The equation y = 12x describes the amount of money Louis earns, where x is the number of hours he works and y is the amount of money he earns.
The table shows the amount of money Carl earns for different numbers of hours worked.
Carl’s Earnings
Time (h) 3 5 8 10
Money earned ($) 45 75 120 150
(a) How much money does Carl earn per hour? Show your work.
(b) Who earns more per hour? Justify your answer.
(c) Draw a graph that represents Carl’s earnings over time in hours. Remember to label the axes.
Carl earns $45 per hour. We cannot determine who earns more per hour without the earnings of Louis given. To represent Carl's earnings over time in hours, a graph can be drawn using the data points provided in the table.
Explanation:To find the amount of money Carl earns per hour, we need to divide the money earned by the number of hours worked. So, for each data point in the table:
For 3 hours worked, Carl earns $45 per hour.For 5 hours worked, Carl earns $75 per hour.For 8 hours worked, Carl earns $120 per hour.For 10 hours worked, Carl earns $150 per hour.From these calculations, we can see that Carl earns $45 per hour.
To determine who earns more per hour, we need to compare the amount of money Carl and Louis earn. Since we do not have Louis' earnings given, we cannot determine who earns more per hour.
Finally, to draw a graph that represents Carl's earnings over time in hours, we can plot the data points from the table on a graph with the x-axis representing time in hours and the y-axis representing money earned. Each data point will be represented by a coordinate (x, y), where x is the time in hours and y is the money earned. Connecting the data points will give us a graph that represents Carl's earnings over time.

Of 350 students polled, some have a cat, some have a dog, and some have both. One hundred seventy-five students have a cat and 140 have both types of pets. How many students have a dog only? Explain.
I believe the answer was:
175; Since 175 have a cat or a cat and dog, then the number that have a dog only is 350 − 175 = 175.

Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth. A. 51.9, 52, 49, 6 B. 52.9, 52, 49, 104 C. 51.9, 53, 49, 6 D. 52, 52.9, 49, 104
Evaluate. 53−(648)+102 Enter your answer in the box.
The final result is 803.
To evaluate the given expression 53 − (−648) + 102, we need to follow the rules of arithmetic operations, particularly the order of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, we look inside the parentheses. Since we have a negative sign before the parentheses, we understand that we are subtracting a negative value which is the same as adding its positive equivalent. So our expression will become 53 + 648 + 102.
Next, we perform the addition operation: 53 + 648 = 701 Adding 102 to 701: 701 + 102 = 803
The final result of evaluating the expression is 803.
