Francine applies the commutative property to the product. (−8/9)⋅(−13)⋅(18) Which expression illustrates the commutative propert

oksian1 [2.3K]

The commutative property implies that, the order of multiplication is not important.

$(-\frac 89) \cdot (18) \cdot (-13)$ is true

Commutative property of multiplication states that:

If $a \times b = b \times a$

The expression is given as:

$(-\frac 89)\cdot (-13) \cdot (18)$

To get the commutative expression, we simply change the position of each factor in the expression.

So, some possible equivalent expressions are:

$(18) \cdot (-13) \cdot (-\frac 89)$

$(18)\cdot (-\frac 89) \cdot (-13)$

$(-13) \cdot (18) \cdot (-\frac 89)$

There are several other equivalent expressions.

From the list of options;

$(-\frac 89) \cdot (18) \cdot (-13)$ is true

A rose bush of height `h` is planted at an initial height of 3 feet. The bush is expected to grow an average of 0.5 feet per yea

noname [10]

Answer:

The height is 4.5ft

Step-by-step explanation:

Given

$Initial\ Height = 3\ ft$

$Growth = 0.5\ ft$ yearly

Required

Determine the height in 3 years

First, we need to determine the growth equation.

Represent the height with h and the years with x

So:

$y = Initial\ Height + Growth * x$

$y = 3 + 0.5 * x$

$y = 3 + 0.5x$

To solve the required, we have that:

$x = 3$

$y = 3 + 0.5x$ becomes

$y = 3 + 0.5 *3$

$y = 3 + 1.5$

$y = 4.5$

<em>Hence, the height is 4.5ft</em>

use the formula a=p(1+r/n)nt to find the compound interest account . zakk deposited $5600.0in an account which compounded 1.9%qu

Komok [63]

Answer:

$A=\$6,768.75$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=10\ years\\ P=\$5,600\\ r=0.019\\n=4$

substitute in the formula above

$A=\$5,600(1+\frac{0.019}{4})^{4*10}$

$A=\$5,600(1.00475)^{40}=\$6,768.75$

The price of a four-year dinner was $100 two decades ago. A report says that a dinner is 250% of what it was 20 years ago, how m

Leviafan [203]

The original price of a shirt was $20. It was decreased to $15 . What is the percent decrease of the price of this shirt.

Solution to Problem 1:

The absolute decrease is

20 - 15 = $5

The percent decrease is the absolute decrease divided by the the original price (part/whole).

percent decease = 5 / 20 = 0.25

Multiply and divide 0.25 to obtain percent.

percent decease = 0.25 = 0.25 * 100 / 100 = 25 / 100 = 25%

Problem 2:

Mary has a monthly salary of $1200. She spends $280 per month on food. What percent of her monthly salary does she spend on food?

Solution to Problem 2:

The part of her salary that is spent on food is $280 out of her monthly salary of $1200

percent = part / whole = 280 / 1200 = 0.23 (rounded to 2 decimal places)

Multiply and divide 0.23 by 100 to convert in percent

percent = 0.23 * 100 / 100 = 23 / 100 = 23%

Problem 3:

The price of a pair of trousers was decreased by 22% to $30. What was the original price of the trousers?

Solution to Problem 3:

Let x be the original price and y be the absolute decrease. If the price was decreased to $30, then

x - y = 30

y is given by

y = 22% of x = (22 / 100) * x = 0.22 x

Substitute y by 0.22 x in the equation x - y = 30 and solve for x which the original price.

x - 0.22 x = 30

0.78 x = 30

x = $38.5

Check the solution to this problem by reducing the origonal price found $38.5 by 22% and see if it gives $30.

Problem 4:

The price of an item changed from $120 to $100. Then later the price decreased again from $100 to $80. Which of the two decreases was larger in percentage term?

Solution to Problem 4:

First decrease in percent

part / whole = (120 - 100) / 120 = 0.17 = 17%

Second decrease in percent

part / whole = (100 - 80) / 100 = 0.20 = 20%
