The total length of wires a b and c is 445 cm wire a is 45 cm longer then wire b and wire b is half as long as wire c how long i

Oksana_A [137]

Answer:

$a = 145\ cm$

Step-by-step explanation:

Given

$a + b + c = 445$

$a = 45 + b$

$b = \frac{1}{2}c$

Required

Determine the length of a

Solve for c in $b = \frac{1}{2}c$

$2 * b = \frac{1}{2}c * 2$

$2b = c$

$c = 2b$

Substitute $c = 2b$ and $a = 45 + b$ in $a + b + c = 445$

$a + b + c = 445$

$45 + b + b + 2b = 445$

$45 + 4b = 445$

Solve for 4b

$4b = 445 - 45$

$4b = 400$

Solve for b

$b = 400/4$

$b = 100$

Recall that: $a = 45 + b$

$a=45+100$

$a = 145\ cm$

Question:

Use the expression to complete the statements.

$(0.5)^{10\\$

________ is the power .

(0.5) is the ________

A ______ is another way to write

Answer:

0.5 is the base

10 is the power

$(0.5)^{10\\ = (\frac{1}{2})^{10}$ -- another way to write

Step-by-step explanation:

Given

$(0.5)^{10\\$

Required

Fill ion the gaps

$(0.5)^{10\\$ is pronounced as; 0.5 raise to the power of 10

From the above statement, we can deduce the following:

0.5 is the base

10 is the power

Lastly, another way to write $(0.5)^{10\\$

Express 0.5 as a fraction

$(\frac{5}{10})^{10}$

Simplify the fraction

$(\frac{5/5}{10/5})^{10}$

$(\frac{1}{2})^{10}$

Hence:

$(0.5)^{10\\ = (\frac{1}{2})^{10}$
