Answer:

A. 1/2 and 3/2

Step-by-step explanation:

You want to identify like fractions among the sets {1/2, 3/2}, {2/1, 2/3}, {10/10, 5/5}, and {7/4, 4/7}.

<h3>Like fractions</h3>

Like fractions are fractions that have the <em>same denominator</em>. Among the sets offered, the only one with denominators the same is ...

Determine the equation of the linear graph that passes through (-2,3) and (4,6). State your answer in the

Lena [83]

The linear equation is y = 4 + 0.5x

<h3>How to determine the equation?</h3>

The points are given as: (-2,3) and (4,6)

The equation is then calculated using:

$y = \frac{y_2 -y_1}{x_2 -x_1} *(x - x_1) + y_1$

Substitute the known values

$y = \frac{6-3}{4+2} *(x+2) + 3$

Evaluate

y = 0.5 *(x+2) + 3

Expand

y = 0.5x + 1 + 3

Evaluate the sum

y = 0.5x + 4

Rewrite as:

y = 4 + 0.5x

Hence, the equation is y = 4 + 0.5x

Casey buys a bracket for. She pays for the bracelet and pays $0.72 in sales tax. The sales tax is 6%. What is the Original price

iren2701 [21]

Answer:

$12

Step-by-step explanation:

amount of tax = $0.72

percent of tax= 6%

Let the original cost be x

so that

6% of x= 0.72

solve for x

6/100*x= 0.72

0.06x= 0.72

divide both sides by 0.06

x= 0.72/0.06

x=$12

Hence the cost is $12

Question 1: find the volume of a cube whose total surface area is 486cm^2

lapo4ka [179]

<h3>The volume of cube is 729 cubic centimeter</h3>

<em><u>Solution:</u></em>

<em><u>The surface area of cube is given as:</u></em>

$Surface\ area = 6a^2$

Where, "a" is the length of side of cube

Given that, surface area = 486 square centimeter

$486 = 6a^2\\\\a^2 = \frac{486}{6}\\\\a^2 = 81\\\\a = 9$

<u><em>Find the volume of cube:</em></u>

$volume\ of\ cube = a^3\\\\volume\ of\ cube = 9^3\\\\volume\ of\ cube = 9 \times 9 \times 9\\\\volume\ of\ cube = 729$

Thus volume of cube is 729 cubic centimeter
