Janice is roller skating at a constant speed away from her house. The first half of the street is flat, but the second half has a steep upward hill. Janice moves more slowly as she skates up the hill.
Which graph shows Janice's position as she roller skates away from her house?
A. Z
B. X
C. W
D. Y
Answers
Answer:
If I had to guess... I think it would be Y
Step-by-step explanation:
The reason why I think its Y is because the line on the graph seems to go constant till it gets to the tip. As you can see the line is less slanted meaning that she is going slower. (If you know what I mean.. I tend to be bad at explaining things hehe..)
2+3/4x=5/12
Rewrite the equation so that it does not have any fractions
Answers
Answer:
24+9x=5
Step-by-step explanation:
First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.
2*12=24,
3/4*12=36/4=9,
5/12*12=60/12=5.
Using these values will give your final equation: 24+9x=5
24+9x=5
Explanation:
To remove the fractional values, we need to multiply both sides of the equation by their denominators so they get canceled out.
2+3/4x=5/12
1) Multiply both sides of the equation by 4 since it is the denominator of 3/4
8+3x=20/12
2) Simplify the fraction 20/12
8+3x=5/3
3) Multiply both sides of the equation by 3 since it is the denominator of 5/3
24+9x=5

Explain how to simplify a ratio. Be sure to include an example to support your response
Answers
A ratio is an expression used to compare two quantities. A simplified ratio can be taken as is, but if a ratio has not yet been simplified, you should do so to make the quantities easier to compare and understand. In order to simplify a ratio, you divide both terms (both sides of the ratio) by the same number.
At the restaurant, the cost of the meal before tax was
$40. The tax is 8.5%, and Sheri wants to leave at least
an 18% tip. Explain how to approximate the total cost of
the meal.
Answers
Answer:
so you add then multiply then subtract
Step-by-step explanation:
Answer:
First we estimate the percent's. 8.5% - 10%, 18% - 20%. Then we do the equation. If you add percent's you get 30% multiply that by 40 and you get 12. Add that to you problem and you get $52.
Step-by-step explanation:
Since the tax and gratuity were 4 and 8 dollars you can just add those up to the 40, but I did it another way.
This is the sample response if you want a better explanation.
The gratuity is about 20% of $40, which is $8. The tax is about 10% of $40, which is $4. So, the total cost is about $40 + $8 + $4 = $52.

Answers
Answer:
A is answer
Step-by-step explanation:
please follow me
Answer:
B and C
Step-by-step explanation:
Since m and n are parallel, we can call the two lines extending from the point B transversals.
[tex]m\angle{1} = 60^\circ[/tex] because they are vertical angles
[tex]m\angle{2} = 20^\circ[/tex] from the corresponding angles theorem.
[tex]m\angle{4} = 60^\circ[/tex] from the corresponding angles theorem.
[tex]m\angle{3} = 100^\circ[/tex] because angle 2 and 4 sum to 80, and [tex]m\angle{2} + m\angle{3} + m\angle{4} = 180^\circ[/tex] because it is a straight angle.
From this, we can see which ones are true.
A is false because angle 2 is 20 degrees.
B is true because angle 3 is 100 degrees.
C is true because angle 2 + angle 4 = 20 + 60 = 80 degrees.
D is false because angle 2 + angle 3 = 20 + 100 = 120 degrees.
Therefore, only B and C are true.
