Answer:9:24
Step-by-step explanation:
We know that they will meet some time $T$ after 8:00 and that $T$ must be a multiple of 4, 7, and 6. So our job is to find the smallest multiple of those three numbers. Since 4 and 7 share no factors, the first number that is a multiple of both will be $4\cdot7=28$. Next, we must find the smallest multiple of 28 and 6. We can do this in two ways: by listing multiples of 28 until we find one that is a multiple of 6 or by finding what factors of 6 that 28 is missing and multiplying by those factors.
Method 1: The multiples of 28 go 28 (not divisible by 6), 56 (not divisible by 6), 84 (which is divisible by 6!)... So the smallest multiple of 4, 7, and 6 is 84.
Method 2: The factors of 6 are 1,2,3, and 6, so we can write 6 as $2\cdot3$. 28 is divisible by 2 but not by 3, so we must multiply it by 3. We find $28\cdot3=84$ and 84 is therefore the smallest multiple of 4, 7, and 6.
Now we just need to find the time that is 84 minutes after 8:00. Since 9:00 is 60 minutes after 8:00, we just need 24 more minutes after that (since $60+24=84$). The final time is therefore $\boxed{9:24}.$
Hence, the earliest time when all three meet back at the beginning is [tex]9:24[/tex].
What is the division?
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.
Here given that,
Anna, Stephanie, and James all start running around a track at [tex]8:00[/tex]. Anna completes a lap every [tex]4[/tex] minutes, Stephanie finishes a lap every [tex]7[/tex] minutes, and James finishes a lap every [tex]6[/tex] minutes.
So, the smallest multiple of [tex]4, 7[/tex] and [tex]6[/tex] is [tex]84[/tex].
Now we just need to find out the time is [tex]84[/tex] minutes so after [tex]8:00[/tex], it would be [tex]9:00[/tex] is [tex]60[/tex] minutes then after [tex]8:00[/tex], we need to move [tex]24[/tex] minutes more after that. The final time is [tex]9:24[/tex].
Hence, the earliest time when all three meet back at the beginning is [tex]9:24[/tex].

Answer:
Number of boys = 12
Number of girls = 36
Step-by-step explanation:
Number of boys = x
Number of girls = 3*x = 3x
Total students = 48

Are the Triangle similar? Why or why not?
Answer:
No, they are not similar
Step-by-step explanation:
The three triangle angles should always add up to 180 degrees.
In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.
In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.
In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.
p = 1/8 + 15/16
Use common denominator, which is 16:
p = 1(2)/8(2) + 15/16
p = 2/16 + 15/16
p = 17/16
17/16 is an improper fraction. If you want to use a mixed number for your answer, then:
17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)

Given
Two congruent angles and two congruent sides
Base on the given description, the concept being described is an isosceles triangle, as it has two congruent sides and two congruent angles.
If each angle measures 45 degrees each, then the third angle is 90 degrees.
This is shown below.
[tex]\theta + 45 + 45= 180[/tex] --- angles in a triangle

The circumference of a circular pond in the park is 120 meters. Find the area.
The formula for circumference is C = d.
What is the value of the diameter rounded to the nearest whole number?
Answer:
38.21 in
Step-by-step explanation:
Given data
C= 120meters
We also know that circumference
C=2πr
