Answer:

Mixed: 722/100

Improper: 7 22/100

Step-by-step explanation:

Since you can't simplify it looks like we have to stay with:

7 -> 700/100

.22 -> 22/100

722/100

.22 -> 22/100

7 + 22/100

What's greater 0.15 or 1/8

shusha [124]

0.15
1/8...." / " means divide....so 1/8 = 0.125

if it makes it easier to compare them, line the decimals up and add 0's to empty spaces...
0.150 (this is the same as 0.15)
0.125

therefore, 0.15 is greater then 1/8

Yvonne deposits $5000 in a bank account which pays 4% per annum compound interest. What is the total interest earned in 5 years,

Marianna [84]

Answer:

Step-by-step explanation:

The compound interest formula is expressed as $A = P(1+r/n)^{nt}$

A is the total amount after n years

P is the amount deposited (principal)

r is the rate (in %)

t is the time (in years)

n is the time of compounding

Given P = $5000, r = 4% = 0.04, t = 5 years, n = 1 year (per annum compound interest)

On substituting into the formula we have;

$A = 5000(1+0.04)^{1(5)} \\A = 5000(1.04)^{5} \\A = 5000*1.2166529\\A = 6,083.26$

Interest earned = Amount - Principal

Interest earned = $6,083.26 - $5,000

Interest earned = $1,083.26 ≈ $1,083

Hence, the total interest earned in 5 years is $1,083 to the nearest dollars.

Zach tried to solve an equation step by step. 34=z−1234+12=z−12+12Step 154=zStep 2\begin{aligned} \dfrac34&=z-\dfrac12\\\\ \

Mazyrski [523]

Question:

Zach tries to solve an equation step by step;

$\frac{3}{4} = z - \frac{1}{2}$

Step 1:

$\frac{3}{4} + \frac{1}{2} = z - \frac{1}{2} + \frac{1}{2}$

Step 2:

$\frac{3}{4} + \frac{1}{2} = z$

$\frac{5}{4} = z$

Find Zach's mistake;

Answer:

Zach didn't make any mistake

Step-by-step explanation:

Given: the steps above

At step 1, he applied addition property of equality by adding $\frac{1}{2}$ to both sides of the equation

Step 2 is a result of step 1 and he rightly added the fractions

Further Explanation;

$\frac{3}{4} = z - \frac{1}{2}$

Add $\frac{1}{2}$ to both sides

$\frac{3}{4} + \frac{1}{2} = z - \frac{1}{2} + \frac{1}{2}$

$\frac{3}{4} + \frac{1}{2} = z$

Take LCM of fractions at the left hand side

$\frac{3 + 2}{4} = z$

$\frac{5}{4} = z$

Reorder

$z = \frac{5}{4}$

<em>Analyzing the steps one after the other, we can conclude that Zach didn't make any mistake;</em>

Gueguen and Jacob asked waitresses to wear different colored T-shirts on different days for a six-week period and recorded the t

jarptica [38.1K]

Answer:

Dependent Variable = tips left by male customers

Independent Variable = T-Shirt color worn by waitresses

Step-by-step explanation:

Dependent variable is the variable that changes when the independent variable changes.

In other words, when the independent variable is varied, the dependent variable changes. The dependent variable is the effect or outcome of the manipulation of the independent variable.

In the study referred to in the question above, the amount of tips given to waitresses is dependent on the color of the T-shirt the waitresses wear.

Therefore, the dependent variable is T-Shirt color, while the independent variable is the amount of tips given.
