Step-by-step explanation:

Pythagorean Theorem

a^2+b^2=c^2

C is the hyptonuse A and B are legs.

a^2+3^2=5^2

a^2+9=25

a^2=16

a= sqrt16

a=4

Hope this helps!

Joe has $70 in a savings account. The interest rate is 10% per year and is not compounded,

sladkih [1.3K]

Answer:

$28

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 70 × 0.1 × 4 = 28

I = $ 28.00

The simple interest accumulated

on a principal of $ 70.00

at a rate of 10% per year

for 4 years is $ 28.00.

Which expression is equivalent to (7x – 5) – (3x - 2)

Nastasia [14]

Answer:

Step-by-step explanation:

We have the expression

$(7x-5)-(3x-2)$

First we need to distribute the negative throughout the parenthesis. Then we can combine like terms in order to simplify this expression

$(7x-5)-(3x-2)\\\\7x-5-3x+2\\\\4x-3$

This answer matches D.

Simplify (5.1)(5.12)4.<br><br> (5.1)6<br> (5.1)7<br> (5.1)8<br> (5.1)9

Andru [333]

The simplified expression of (5.1)(5.1^2)^4 is (5.1)^9

<h3>How to simplify the expression?</h3>

The expression is given as:

(5.1)(5.12)4

Rewrite the expression properly as follows:

(5.1)(5.1^2)^4

Rewrite the expression properly as follows:

(5.1)(5.1^2)^4 = (5.1) * (5.1^2)^4

Apply the power law of indices

(5.1)(5.1^2)^4 = (5.1) * (5.1^8)

Apply the power law of indices

(5.1)(5.1^2)^4 = (5.1)^(1 + 8)

Evaluate the sum

(5.1)(5.1^2)^4 = (5.1)^9

Hence, the simplified expression of (5.1)(5.1^2)^4 is (5.1)^9

What is the simplified form of the following expression? 2 startroot 18 endroot 3 startroot 2 endroot startroot 162 endroot

nataly862011 [7]

The simplified form of the provided expression of 2 startroot 18 endroot +3 startroot 2 endroot startroot +162 endroot is 18√2.

<h3>What is the simplified form of an equation?</h3>

The simplified form of an equation is the simplest way of expressing the equation, by applying the required operations of mathematics.

The equation provided in the problem is,

$2\sqrt{18}+3\sqrt{2}+\sqrt{162}$

Let the simplified form of the above expression is <em>n. </em>Thus,

$n=2\sqrt{18}+3\sqrt{2}+\sqrt{162}$

Rewrite the equation to solve it further as,

$n=2\sqrt{3\times3\times2}+3\sqrt{2}+\sqrt{9\times9\times2}\\n=2\sqrt{3^2\times2}+3\sqrt{2}+\sqrt{9^2\times2}$

The square of the term cancel out the square root of it. Thus,

$n=2\times3\sqrt{2}+3\sqrt{2}+9\sqrt{2}\\n=6\sqrt{2}+3\sqrt{2}+9\sqrt{2}\\n=(6+3+9)\sqrt{2}\\n=18\sqrt{2}$

Thus, the simplified form of the provided expression of 2 startroot 18 endroot +3 startroot 2 endroot startroot +162 endroot is 18√2.
