There are 5,000 books in the town's library. Of these, 4,900 are fiction. To
find the percent of the books that are fiction, first set up the percent equation. Then find the percent.
Setup the percent equation. Choose the correct answer below.
A. 5,000 = m times 4,900
B. 5,000 = m divided by 4,900
C. 4,900 = m times5,000
D. 4,900 = m divided by5,000
(type whole number)
thank u so much!!
i will give brainliest to the correct answer!!
Answer:
C. 4,900 = m times 5,000
Step-by-step explanation:
Total books = 5,000
Fiction = 4,900
Calculations:
[tex]5,000. \frac{x}{100} =4,900[/tex]
[tex]\frac{x}{100} = \frac{4,900}{5,000}[/tex]
[tex]\frac{x}{100} =0.98[/tex]
[tex]x=98[/tex]
Now that we know x we can come up with the equation and can determine which one is correct. x = m = 98%
Therefore, 4,900 is 98% of 5,000.
So 5,000 x 98% = 4,900
And the equation that matches that is C.
Suppose two trains, say A and B are initially 125 miles apart on the same east-west track. Train A is initially to the west of train B. Train A begins to head due east at 25 mph, and train B begins to head due west at 20 mph. To the nearest minute, how long will it take for the two trains to collide?
Answer:
[tex]167\ \text{minutes}\text{ or }166\ \text{minutes}\ \text{and}\ \text{40}\ \text{seconds}[/tex]
Step-by-step explanation:
Distance between the two trains is 125 miles.
So, when they will collide they would have covered a distance of 125 miles together.
The time that will pass for both the trains will be same but the distances covered will be different as their speeds are different.
[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]
[tex]25t+20t=125\\\Rightarrow t=\dfrac{125}{45}\\\Rightarrow t=\dfrac{25}{9}\ \text{hours}=\dfrac{25}{9}\times 60\times 60=10000\ \text{s}=166.67\ \text{minutes}\\\approx 167\ \text{minutes}\\=166\ \text{minutes}\ \text{and}\ \text{40}\ \text{seconds}[/tex]

A zebra can run at a constant speed of 0.6 miles per minute. How far can a zebra run in 30 minutes? Choose the equation that could be used to answer this question. d=(0.6)(0.5)
I think the options were omitted, so i will go ahead and solve. From my answer, you can choose the right option
Answer:Equation to solve the question
=Distance = Speed x time
=d= 0.6 x 30
Distance , d= 18 miles
Step-by-step explanation:
Step 1
Speed = distance / time
Therefore Distance = Speed x time
Given that speed = 0.6 miles per minute and
Time=30 minutes
Step 2
Distance ,d= 0.6 miles per minute x 30minutes
d= 0.6 x 30
= 18miles

Answer:
75 degrees
Step-by-step explanation:
At 3:30, the hour hand is halfway between the 3 and the 4. The minute hand is exactly on the 6.
There are 360/12 = 30 degrees between each of the marked hours. The angle between the hands covers 2.5 of these gaps, so the angle between the hands is 2.5(30) = 75 degrees.
Hope this helps!
The angle between the hands at 3:30 pm is 90°.
What is the angle between the hands of a clock at 3:30 pm?
At that time, one hand points at the 3, and the other hand points at the 6.
Now, there is a rule to transform time into angles.
We know that a clock has 12 hours in a full revolution, and a circle has 360° in a complete revolution.
Then we know that:
12 hours = 360°
Then:
1 hour = (360°/12) = 30°
So each between each number in the clock we have an angle of 30°.
Then, between 3 and 6 (3 hours) we have:
3*30° = 90°
The angle between the hands at 3:30 pm is 90°.

A year membership to Fun Zone costs $45 plus $1 per visit. A one-month membership costs $5 plus $3 per visit. Which multi-step equation, with variable on both sides, represent this situation
Answer:
y = $45 + x
y = $5 + 3x
Step-by-step explanation:
The computation of the multi-step equations be shown below:
Let us assume the number of visits be x
So the first equation would be
y = $45 + x
And, the second equation would be
y = $5 + 3x
These are the multi-step equations with variable on the both sides
Two groups of bikers leave the same camp heading in different directions. Each group travels 4 miles, then changes direction and travels 1.4 miles. Group A starts due east and then turns 48° toward north. Group B starts due west and then turns 32° toward south. Which group is farther from camp?
1. Group A is farther from camp.
2. Group B is farther from camp.
3. Group A and Group B are the same distance from camp.
4. Not enough information is given.
Group B is farther from camp.
Group B is farther from camp in comparative to other Group A.
What is Direction Sense?Direction sense ability is to find one's way around easily in a new place a good/poor sense of direction.
Here, Distance travel together = 4 miles.
After changing their direction distance covered by them = 1.4 miles.
Group A turns 48⁰ towards north
So, total distance covered by group A = 1.4 + 4 X sin 48⁰
= 1.4 + 4 X 0.7341
= 4.34 miles.
Group B turns 32⁰ towards south.
Similarly, distance covered by group B = 1.4 + 4 X cos 32⁰
= 1.4 + 4 X 0.8480
= 4.79 miles.
Thus, Group B is farther from camp in comparative to other Group A.
