Answer:

163,259,561,310

Step-by-step explanation:

To make this easier, first multiply the first two numbers:

2,357x8,870

I can take this apart using place values to make this easier:

2,000x8,000=16000000

300x800=240000

50x70=3500

7x0=0

Then add all these values together:

16000000+240000+3500+0=20906590

Then multiply that value by the remaining value to get your answer:

20906590x7809=163259561310

4) (Assume AR is tangent) Given: AR 12 SR - 7.7 Find: cs (Round to nearest tenth.)

andreev551 [17]

The length of CS is 11.0

Explanation:

Given that the length of the tangent AR is 12

The length of SR is 7.7

To find: The length of CS

The tangent secant theorem states that "if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant."

Applying the tangent secant theorem, we have,

$AR^2=SR\times RC$

Rewriting the above equation, we get,

$AR^2=SR(SR+SC)$

Substituting the values, we get,

$12^2=7.7(7.7+CS)$

Simplifying, we have,

$144=59.29+7.7CS$

Subtracting both sides by 59.29, we get,

$84.71=7.7CS$

Dividing both sides by 7.7, we have,

$11.0013=CS$

Rounding off to the nearest tenth, we get,

$11.0=CS$

Thus, the length of CS is 11.0

Wendy has 5 and 1 over 3 feet of ribbon. How many 2 over 3 foot pieces can Wendy cut from the 5 and 1 over 3 feet of ribbon? Sho

denis-greek [22]

Answer:

Your answer is 8

Step-by-step explanation:

First you have to convert the mixed number into an improper fraction. To do this, multiply the denominator by the whole number. Then add the numerator and put that answer in a fraction over the original. So it would be 3*5=15+1=16/3. So now that the denominators are the same, all you need to do is see how many times 2 goes into 16. 16/2 which is 8. Answer = 8
