Answer:
2^-2
Step-by-step explanation:
According to the properties of integer exponents, 1/a^n = a^-n.
So 1/2 x 1/2 = 1/2^2 = 2^-2.
1/2 x 1/2 can be rewritten as the exponential expression 2^-2.
Edmentum answer
The expression 1/2 × 1/2 can be written as 2⁻² in the exponential form with the base 2.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 1/2 × 1/2.
We have to write the expression in an exponential form with the base 2.
1/2 × 1/2 = (1/2)²
= 1 / 2²
We have the rule for exponentiation 1 / aᵇ = a⁻ᵇ
1/2 × 1/2 = 2⁻²
Hence the exponential form of the given expression with the base 2 is 2⁻².

a fruit salad contains 20 different pieces of fruit. there are 3 pieces of apple, 8 pieces of watermelon, 7 pieces of banana, and the rest are orange pieces.
What is the missing side length?
(Use Pythagorean Theorem)
Answer:
20 units
Step-by-step explanation:
The Pythagorean Theorem states that:
[tex]a^{2} + b^{2} = c^{2} \\[/tex]
Now we can insert values into the equation.
[tex]a = 15\\b = b\\c = 25\\[/tex]
Now we can plug these ☝ values into the Pythagorean Theorem:
[tex]15^{2} + b^{2} = 25^{2}\\[/tex]
After we solve for [tex]b[/tex] we get:
[tex]b^{2} = 400\\b = 20[/tex]
Answer:
b = 20
Step-by-step explanation:
15 + b = 25
(you have to square each one)
15 x 15 = 225
b x b = b
25 x 25 = 625
625 - 225 = 400
[tex]\sqrt{400}[/tex] = 20

Solve for r.
-13 = r/9 + 8
r = ???
Answer:
r= -189
Step-by-step explanation:
Answer:
r= -189
Step-by-step explanation:
You subract the 8 both sides: -13= r/9+8
Which equals to: -21= r/9
In order to get the 9 off, you have to cancel it by multiplying ( opposite of is multiplying) both sides:
9(-21)= r
And the final answer is: r= -189
You can check it by plugging in -189 to r and it works:)

A motorboat, that has speed of 10 km hour in still water, left a pier traveling against the current of the river. Forty-five minutes after the boat left the pier, the motor of the boat broke, and the boat began drifting with the current. After three hours of drifting with the current, the boat was back at the pier where it had started. What is the speed of the current of the river?
9514 1404 393
Answer:
2 km/h
Step-by-step explanation:
distance = speed × time
The boat's progress upriver can be modeled by ...
