Answer:
$8036.784
Step-by-step explanation:
It is easy
The area of carpet is 13.4×24=321.6sq meter
Now, for 1 sq. meter the cost is $24.99
So for 321.6sq.meters, 321.6×24.99
=$8036.784
Answer:
5 un^2
Step-by-step explanation:
the liens from (0, 0) to (1, 3) and (1, 3) to (4, 2) are perpendicular meaning that the angle at (1, 3) is a right angle
to find the lengths of the sides we must use the pythagorean theorem
a^2 + b^2 = c^2
for the leftmost side
we have 1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
for the top side
we have
the same thing
1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
you must multiple sqrt(10) by sqrt(10) and then by 1/2
sqrt(10) * sqrt(10) is 10
10 * 1/2 is 5
the area is 5 un^2
255 x 32 = 8,160
8,160 / 1,000 = 8 liters and 160 milliliters
32 bottles will hold 8 liters of shampoo
Answer:
x = 16
Step-by-step explanation:
Let the second number be <em>x</em>.
The first number = <em>2</em><em>x</em>
The third number = <em>2</em><em>×</em><em>2</em><em>x</em><em> </em>= <em>4</em><em>x</em>
<em>2</em><em>x</em><em> </em><em>+</em><em> </em><em>x</em><em> </em>+<em> </em><em>4</em><em>x</em><em> </em>= <em>1</em><em>1</em><em>2</em>
<em>7</em><em>x</em><em> </em>= <em>1</em><em>1</em><em>2</em>
<em>x</em><em> </em>= <em>1</em><em>1</em><em>2</em><em>/</em><em>7</em>
<em>x</em><em> </em>= <em>1</em><em>6</em>
