Solve for x 20 points

torisob [31]

Answer:

x = 21 units

Step-by-step explanation:

The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.

So here, that will look like: 36² = 27 * (27 + x)

Expansion and multiplication gives us: 1296 = 729 + 27x

Subtract from both sides: 567 = 27x

Divide from both sides: x = 21.

Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

= $\frac{9}{12} years$

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

$Interest = Principal \times Rate \times time$

$116.25=1550 \times r \times \frac{9}{12}$

$r= \frac{116.25 \times 12}{1550 \times 9}$

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%

13.24503311258278 Round to the nearest tenth as needed

Ksenya-84 [330]

The number provided rounded to the nearest tenth is 13.2.

Because the number in the hundreds place is a 4, we round down and keep the tenth at 2.

A 48-year-old person is 4.2048 × 105 hours old. Write this number in standard form.

Fynjy0 [20]

4.2048 x 105 = 441.504

the standard form should be between 1 and 9 so the decimal point should be after the first digit (4)

it would look like this 4.41504 x 10 to the power of 2 because it moved back two places. hope it makes sense? (:
