Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points

If f(x)=6x-15 and f(a)=30, what is the value of a? Please help

mariarad [96]

Answer:

$a=7.5$

Step-by-step explanation:

Given the function $f(x)=6x-15$ and the output $30$ when $x=a$ , we can write the equation:

$6a-15=30$

$6a=45$

$a=7.5$

We can insert the value of $a$ into the function to verify the output equals $30$ :

$f(a) = 6a-15$

$= 6(7.5)-15$

$=30$

∴ We have verified that $a=7.5$

Hope this helps :)

Which equations illustrate the associative property of addition? Choose exactly two answers that are correct.

sveticcg [70]

Solutions

Associative Property is a rule that refers to grouping. The rule is "a + (b + c) = (a + b) + c".

The correct answers are (A) and (D)

(A) = (11 + 2.2) + (–5) = 11 + [2.2 + (–5)]

(D) = –7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)
