b = 78°

The angles at a point sum to 360°

that is 45 + 237 + b = 360

282 + b = 360 ( subtract 282 from both sides )

b = 360 - 282 = 78°

Evaluate the expression without using the calculator 8^1/3
allsm [11]

Answer:

= 2.67

Step-by-step explanation:

Given: 8^1/3

We have to find the value of the given fraction which can be done by dividing the denominator value with the numerator value

                                  \frac{8^1}{3} \\

 The power of 8 is '1', so, the value of numerator is 8.

                                    \frac{8}{3}

The value of the fraction is calculated by dividing 3 by 8.

                         = 2.67

Circle O has a circumference of approximately 250ft. What is he approximate length of the diameter, d?
Alja [10]

Circumference = pi *d

250 = pi * d

divide each side by pi

250/pi = d

pi is approximately 3.14

250/3.14 = d

79.62 = d

the diameter is approximately 79.62 ft

14/1 ÷ 3/8 = please show work and answer fast​
jarptica [38.1K]

Answer: 37 1/3

Step-by-step explanation:

14/1÷3/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

14/1 × 8/3=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

14×8/1×3 = 112/3

This fraction cannot be reduced.

The fraction

112/3

is the same as

112÷3

Convert to a mixed number using

long division so

112/3=37 1/3

Therefore:

14/1 ÷ 3/8=37 1/3

Write a number in which the value of the 3 is ten times greater than the value of the 3 in 135, 864
Aleonysh [2.5K]

Answer:

345,456

Step-by-step explanation:

The value of 3 in 135,864 is 30,000.

We want to write a number that is ten times 30,000.

We could write any other number in which the value of 3 is 300,000.

There are infinitely many numbers that we can write.

Some examples are:

345,456

1,315,445

5,354,456

and so on and so forth.
