Answer:
food A has fewer calories
Step-by-step explanation:
food b has 250 cal. in 2/3 of a serving and food a has only 150 in 3/4 of a serving, and because it is 3/4 we can know that the last amount of cal. in food a is 50, meaning that with all the calories in the full serving, it has less calories then food b with a fraction of the calories. food a is the answer
Looks like the expression is
(2⁸ • 5⁻⁵ • 19⁰) • (5⁻² / 2³)⁴ • 2²⁸
First, any positive number raised to 0 is 1:
(2⁸ • 5⁻⁵ • 1) • (5⁻² / 2³)⁴ • 2²⁸
(2⁸ • 5⁻⁵) • (5⁻² / 2³)⁴ • 2²⁸
Exponents in a denominator can be rewritten as negative exponents in the numerator:
(2⁸ • 5⁻⁵) • (5⁻² • 2⁻³)⁴ • 2²⁸
Distribute the 4th power across the product 5⁻² • 2⁻³ :
(5⁻² • 2⁻³)⁴ = 5⁻⁸ • 2⁻¹²
so we have
(2⁸ • 5⁻⁵) • (5⁻⁸ • 2⁻¹²) • 2²⁸
Multiplication is associative, so we can ignore the parentheses. Combine factors with equal bases and simplify the exponents:
2⁸ • 5⁻⁵ • 5⁻⁸ • 2⁻¹² • 2²⁸
2⁸⁻¹²⁺²⁸ • 5⁻⁵⁻⁸
2²⁴ • 5⁻¹³
Rewrite the negative exponent as a positive one:
2²⁴ / 5¹³
So the lot has (6/(6+5))*100 percent of new cars and 66*(6/11)*100 percent = 36 new cars before the sale, hence 66-36 =30 preowned cars before sale. After the sale it’s 32 new cars and 28 preowned so 32/28 makes it 8/7
You need to substitude the value into the formula given
1/2(3)^3 + 3.4(4)
= 1/2(27) + 13.6
= 27/2 + 13.6
= 27.1
