Find the circumference of a circle that has a diameter of 4 m..

Mathematics
1 answer:
Gnesinka [82]3 years ago
6 0

If diameter = 4,

then radius = 4/2 = 2m.

Formula for the Circumference of a Circle = 2\pir

2\pir = 2 x 22/7 x 2

2 x 22/7 x 2 = 4 x 22/7 = 88/7

= 12.5714286 cm.

It can be also be rounded up into 12.6 cm.

So, the Circumference of the Circle is 12.6 cm or 12.5714286 cm.

A toy company produces 1,000 toys per month. In January, 75 toys did not meet quality standards. The toy company generates a ran
erik [133]
Based on this sample, 100 toys will not meet standards.

There is 1 value that is 75 or lower in this simulation.  This makes the experimental probability 1/10.  1/10(1000) = 100 toys for the month.

I need help to find the measures and equation pls.
siniylev [52]

Answer:

Equation: 7x + 8x = 180

x = 12

∠CBA = 84

∠CFH = 96

Step-by-step explanation:

We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.

We know that the sums of two angles on a straight line are going to be equal to 180.

∠CBA = 7x

∠CFH = 8x

To find the value of x, we must do the following:

7x + 8x = 180

15x = 180

15x/15 = 180/15

x = 12

Now we just substitute to find the angle measures:

∠CBA = 7 · 12 = 84

∠ CFH = 8 · 12 = 96

15. The dollar amount y that remains to be repaid on a loan x months after the loan is issued is represented by y=-1000x + 8000.
irina [24]

Answer:

1) $8000

2) $1000

3) 8 months, since y represents our remaining amount to be paid, we set it equal to 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.

Step-by-step explanation:

We have the equation y = -1000x + 8000 which follows the linear equation:

y = mx + b, where m is our slope and b is our y-intercept

1) The initial balance can be found with our constant "b" which in this case is 8000. You can also plot the function of y and you will find that 8000 is the intercept when x = 0, aka the start

2) We can calculate the rate of change for when the loan is repaid by looking at the slope "m", in this case it is 1000. It subtracts 1000 each month, meaning $1000 is being payed and taken out of the bank account

3) To find how many months it will take for the loan to be repaid, let's solve for x when y = 0.

0  = -1000x + 8000

-8000 = -1000x

8 = x

It will take 8 months. Why? Since y represents our remaining amount to be paid, we set it = 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.
