Toys r us is having a 38% off sale on all backpacks. if a backpack normally costs $22.00, how much will it be on sale?

Fudgin [204]

we know that

$38\%= \frac{38}{100} =0.38$

The price on sale will be equal to

$(1-0.38)*\$22.00=0.62* \$22.00=\$13.64$

therefore

the answer is

$\$13.64$

A piece of wire is 8/9 meter long broke into two pieces. One piece is 2/3 meter long. How long is the other?

Genrish500 [490]

Answer:

<h2>2/9 is the answer.</h2>

Step-by-step explanation:

1. First, make an equation.

Given:

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

Unknown:

Second part of wire

2. Make the numbers have equal denominators

2/3 * 3/3

= 6/9

3. Solve

8/9 - 6/9

= 2/9

What is the perimeter of the rectangle shown on the coordinate plane, to the nearest tenth of a unit?

Pavel [41]

see the attached figure to better understand the problem

Let

x------> the length side of a rectangle

y-------> the width side of a rectangle

we know that

the perimeter of a rectangle is equal to the formula

$P=2x+2y$

In this problem

$AB=DC=x\\AD=BC=y$

Step 1

Find the distance AB

$A(-6,4)\\B(4,2)$

we know that

the distance's formula between two points is equal to

$d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}$

substitute the values

$dAB=\sqrt{(2-4)^{2} +(4+6)^{2}}$

$dAB=\sqrt{(-2)^{2} +(10)^{2}}$

$dAB=\sqrt{104}\ units=10.2\ units$

Step 2

Find the distance BC

$B(4,2)\\C(3,-3)$

we know that

the distance's formula between two points is equal to

$d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}$

substitute the values

$dBC=\sqrt{(-3-2)^{2} +(3-4)^{2}}$

$dBC=\sqrt{(-5)^{2} +(-1)^{2}}$

$dBC=\sqrt{26}\ units=5.1\ units$

Step 3

Find the perimeter

we know that

the perimeter of a rectangle is equal to the formula

$P=2x+2y$

$P=2AB+2BC$

substitute the values of the distance in the formula

$P=2*10.2+2*5.1=30.6\ units$

therefore

the answer is

The perimeter of the rectangle is equal to $30.6\ units$

Which one of these data sets has a mean that is different from the others?

Kamila [148]

Answer:

The top right graph.

Step-by-step explanation:

If you find the mean for all the graphs you get:

Graph 1: 7 Graph 2: 2

Graph 2: 7 Graph 4: 7

To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:

8 + 8 +8 +8 +8 +8 +1 = 49 Add the data points

49 / 7 = 7 Divide by the total amount of points which is seven
