18 out of the 25 students are going on the field trip. What percent of the students are going on the field trip?

can you provide the math to please

Answers

Hello.
To find the percentage of how many students went on the field trip, we simply divide 18 by 25.
18/25 = 0.72

Convert decimal into fraction.
0.72 = 72%

Thus, 18 out of 25 students = 72% of students who are going on the field trip.

how would I solve 4 1/19 × 1 10/21 ?

Answers

First put them into improper fractions which are 77/19 and 31/21, then multiply 77 and 31 and get 2387, and multiply the denominators 19 and 21 which is 399. Then u can put it into a simplified fraction of u wnat

The answer is 5 [tex] \frac{56}{57} [/tex]. 1.)Transform the mixed numbers into proper fractions. 4 [tex] \frac{1}{19} [/tex] = 19x4 = 76+1=77=[tex] \frac{77}{19} [/tex]. 1 [tex] \frac{10}{21} [/tex] = 21x1=21+10=31= [tex] \frac{31}{21} [/tex].
2.) Multiplying two fractions. [tex] \frac{77}{19} [/tex] x [tex] \frac{31}{21} [/tex]=[tex] \frac{2387}{399} [/tex]. 3.) Simplifying a fraction. [tex] \frac{2387}{399} [/tex] = [tex] \frac{341}{57} [/tex]. 4.) Since the numerator greater then the denominator, convert the improper fraction to mixed number. [tex] \frac{341}{57} [/tex] = 56+5x57/57 = 5 [tex] \frac{56}{57} [/tex]

At 9 am a car (A) began journey from a point, traveling at 40 mph. At 10 am another car (B) started traveling from the same point at 60 mph in the same direction as car (A). At what time will car B pass car A?

Answers

When car B passes car A, they will have traveled the same distance, d.

speed = distance/time

distance = speed * time

Car A travels t time.
Since car B starts an hour later, car B travels t - 1 time.

Car A:
d = st
s = 40t

Car B:
d = st
d = 60(t - 1)

The distance are equal, so

40t = 60(t - 1)

40t = 60t - 60

-20t = -60

t = 3

Car A started at 9 am.
9 am + 3 hours = noon.

Answer: at noon.

Can anyone explain this to me?

Answers

Yes, because of the Angle Angle Similarity Property. Angle U in the larger triangle measures 55 degrees. Angle X of the smaller triangle is unknown, but in the polygon formed by the smaller triangle inside the larger, X is equal to 125. Since both values of X form a straight line, they must add up to 180. So subtract 125 from 180 and you get 55. This would prove that at least one angle is equal, and then if you look at the top angles of the triangle, they both have Angle U, so they must also be equal. The third choice is correct.

72 is 48% of what number

Answers

72/1 x 48/100
= 18/1 x 48/25
= 864/25
= 34 14/25

The number for which 72 is 48 percent of is approximately equal to 150.

To find the number that corresponds to 72 being 48% of it, set up an equation.

Let "x" represent the unknown number.

The equation for "72 is 48% of x" can be written as:

72 = 0.48 × x

To solve for "x," divide both sides of the equation by 0.48:

x = 72 / 0.48

x ≈ 150

Therefore, 72 is 48 percent of approximately 150.

On a string of red and blue lights, the red lights blink everyb3 seconds, and the blue lights blink every 5 seconds. How many times will they blink at the same time in one minute?

Answers

when will they blink together?
what is the smallest number they both mutiply to
3*5=15
so every 15 seconds
so at 15, 30, 45, 60 seconds
so 4 times if you count the time exactly at 1 minute

Final answer:

The red and blue lights will blink at the same time 4 times in one minute.

Explanation:

To determine how many times the red and blue lights will blink at the same time in one minute, we need to find the time at which both the 3-second cycle of the red light and the 5-second cycle of the blue light coincide. This is equivalent to finding the least common multiple (LCM) of 3 and 5. The LCM of 3 and 5 is 15, which means they will blink at the same time every 15 seconds.

Since there are 60 seconds in a minute, we need to find how many times 15 seconds fit into 60 seconds. 60 ÷ 15 = 4. Therefore, the red and blue lights will blink at the same time 4 times in one minute.

Answer: The red and blue lights will blink at the same time 4 times in one minute.

Find the measure of the numbered angles

Answers

Well...
Some information was cut off but I'll assume that its a parallelogram.
If it's a parallelogram, then angles 1 and 3 are equal and angle 2 and the angle marked as 110 degrees are equal.
Next we know that angles 1 and 2 are supplementary(adds to 180) so angle 1 is 70 degrees.
Because angle 3 is equal to angle 1, angle 3 is also 70 degrees.

Mckenzie and Cara both tried to find the missing side of the right triangle. Is either of them correct? Explain your reasoning.

Answers

Since it is a right triangle, we can use the pythagorean theorem:

a^2+b^2=c^2

5^2 + 13^2 = c^2

25 + 169 = c^2

194 = c^2

c = sqrt(194)

How do you solve this using the elimination method of systems of equations?

Answers

x-2y=14 | *-1
x+3y=9

-x+2y=-14 } +
x+3y=9
---------------
5y=-14+9
5y=-5
y=-5/5
y=-1

x+ 3*(-1)=9
x-3=9
x=9+3
x=12

Since you want to eliminate in the variable, eliminate x because it can be easily crossed out. To get rid of x simply subtract the two equations. So x-x is canceled and 2y- -3y=5y and 14-9=5 so 5y=5 is 1. Now plug 1 into y and you get x=6.

Therefore, 64 mi/h = 9.39 ft/s.
