Answer:

P= 4s

P= 4(45)

P= 180 in.

Explanation: write down the formula first. Then write down P= 4s, but change the "s" to the 45. Then multiply 45 by 4 then you have your answer. If your teacher ask you for an degrees it will be 180°. Which is also the sum of a triangle.

Laura bernett is 5 ft-4 inches tall. she stands 12 feet from a streetlight and casts a 9-foot-long shadow. how tall is the stree
xxMikexx [17]
The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches

The streetlight is 12 ft 5 1/3 inches tall.

What is the simplified value of the exponential expression 16^1/4?
erik [133]
<h2>Answer</h2>

2

<h2>Explanation</h2>

First, we are going to use the law of fractional exponents: a^{\frac{1}{n} =\sqrt[n]{a}

We can infer form our expression that a=16 and n=4, so let's replace the values:

a^{\frac{1}{n} =\sqrt[n]{a}

16^{\frac{1}{4} }=\sqrt[4]{16}

Notice that we can also decompose 16 into prime factors to get 16=2^4, so we can rewrite our expression as follows:

\sqrt[4]{16}=\sqrt[4]{2^4}

Finally, we can use the rule of radicals: \sqrt[n]{a^n} =a, so:

\sqrt[4]{2^4}=2

15 is at least the quotient of a number and 6 increased by 3
crimeas [40]

Answer:

The number is x\geq 72

Step-by-step explanation:

Given:

Quotient \geq 15

Let the number be x

The quotient is 15 of a number and 6 which is increaase by 3

Hence forming the inequality expression from the question given we get;

\frac{x}{6}+3\geq 15

Now Solving the above equation we get,

\frac{x}{6}+3\geq 15\\\\\frac{x}{6}\geq 15-3\\\\\frac{x}{6}\geq 12\\\\x\geq 12\times6\\x\geq 72

Hence the number is x\geq 72
