Solve the problem 8 - 2 9/14=
Need help with this bc I suck at math:(
Answer:
-45c
Step-by-step explanation:
Answer:
4c
Step-by-step explanation:
[tex]\frac{-60*c^{7} }{-15*c^{4}}[/tex]
Let's reduce the numbers and then we'll reduce exponents of c.
[tex]\frac{-60}{-15}=4[/tex]
Using exponent rules, we simply subtract the exponent from the top and the exponent from the bottom.
7 - 6 = 1
The exponent of c is 1, which is just c
Combining this, we get 4c
Two boys A and B are a two diametrically opposite points on a circle. at one instant the two start running on the circle
Step-by-step explanation:
let the distance travel by both be a&b
a has a distance of d1 like wise b
speed=distanc/time
d1=2v
d2=4v
total distance
d1+d2=180
2v+4v=180
6v=180
v=30
d1=2*30
d1=60
d2=4*20
d2=120
now start u get u starting
not that there meet at same point so now calculate the time they will trave in there various direction
time=distance/velocity
but they but move at a standard velocity
Answer:
is this the full question: Two boys A and B are at two diametrically opposite points on a circle. At one instant the two start running on the circle; A anticlockwise with constant speed v and B clockwise with constant speed 2v. In 2 minutes, they pass each other for the first time. How much later will they pass each other for the second time?
if yes than this is the answer:-
A speed = v
B speed = 2v
Time to meet = 2 minutes
d= pi r ( distance they have to run to meet)
they are running towards each other.
(2v+v)
speed = 3v
d=rt
pi*r = 3v*2
r= 6v/pi
circumference = 2* pi*r
=2*pi*(6v/pi)
=12v
...
Now distance to travel to meet = 12v
speed = 3v
t=d/r
t= 12v/3v
t= 4 minutes
I hope this helps a little bit.
please help find the perimeter
Answer:
Perimeter of the given figure = 28 units
Step-by-step explanation:
Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH
Length of AB = 4.5 units
Length of BC = 2 units
Length of CD = 2 units
Length of DE = 4 units
Length of EF = 5.5 units
Length of FG = 1.5 units
Length of HG = 1 units
Length of AH = 7.5 units
Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5
= 28 units

PLEASE ANSWER ASAP FOR BRAINLEST!!!!!!!!!!!!!!!!!!!!!!!
Answer:
18 grids for each side
have a nice day ^_^
Answer:
8.0 represents how many squares there are on one side but that will measure to be 4mm on each side. We need to make it 9mm on each side by making the processor bigger and adding 5mm.
½=0.5 and thats 1 square.
Expand each side by 10 and that'll make the processor 9mm.

Answer:
707 bags of sand
Step-by-step explanation:
To find the area all you have to do is add 40+5+5=50 then you split that in half to get the radius. The you use the area formula to get the entire shape and the get the radius of the smaller circle. Then, you subtract the small circle from the big circle to get the amount of sand needed. When you do that you should get 706.86 but since you need a whole number you would round up to 707
How do you find a fraction between 1 4/6 and 1 5/6? ILL GIVE BRAINLEST

Answer:
A. [tex] 4\sqrt{6} [/tex]
Step-by-step explanation:
Applying the leg rule which is:
[tex] \frac{Hypotenuse}{leg} = \frac{leg}{part} [/tex]
Hypotenuse = 4 + 8 = 12
Leg = x
Part = 8
Plug in the values
[tex] \frac{12}{x} = \frac{x}{8} [/tex]
Cross multiply
[tex] x*x = 8*12 [/tex]
[tex] x^2 = 96 [/tex]
[tex] \sqrt{x^2} = \sqrt{96} [/tex]
[tex] x = \sqrt{16 * 6} [/tex]
[tex] x = 4\sqrt{6} [/tex]

A college student takes the same number of credits each semester. She had 12 credits when she started, and after
semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?
Answer:
The student obtains his 12 credits each semester during 8 semesters.
Step-by-step explanation:
Since a college student takes the same number of credits each semester, and she had 12 credits when she started, and after
semesters, she had 96 credits, to determine the rate at which she is earning credits, the following calculation must be performed:
96/12 = 8
Thus, the student obtains his 12 credits each semester during 8 semesters.

How do I solve 1 1/3 × 2 2/4 is steps?
Answer:
40/12 or 3 1/3
Step-by-step explanation:
To multiply mixed numbers, first change any mixed number to an improper fraction. Then multiply the numerators together and the denominators together
1 1/3 as an improper fraction is 4/3 and 2 2/4 as an improper fraction is 10/4.
4*10=40
3*4=12

What is 566.8 divided by 52
Step-by-step explanation:
Step 1
The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:
5 5 2
Step 2
We can work out that the divisor (5) goes into the first digit of the dividend (5), 1 time(s). Now we know that, we can put 1 at the top:
1
5 5 2
Step 3
If we multiply the divisor by the result in the previous step (5 x 1 = 5), we can now add that answer below the dividend:
1
5 5 2
5
Step 4
Next, we will subtract the result from the previous step from the second digit of the dividend (5 - 5 = 0) and write that answer below:
1
5 5 2
- 5
0
Step 5
Move the second digit of the dividend (2) down like so:
1
5 5 2
- 5
2
Step 6
The divisor (5) goes into the bottom number (2), 0 time(s), so we can put 0 on top:
1 0
5 5 2
- 5
2
Step 7
If we multiply the divisor by the result in the previous step (5 x 0 = 0), we can now add that answer below the dividend:
1 0
5 5 2
- 5
2
0
Step 8
Next, we will subtract the result from the previous step from the third digit of the dividend (2 - 0 = 2) and write that answer below:
