Answer:

62 square units

Step-by-step explanation:

Top or bottom is 5 x 3, surface area is 15

front or back is 3 x 2, area = 6

left or right is 5 x 2, area = 10

so total area is 2*(15 + 6 + 10) = 62 square units

Answer:

The total of people in the Cinco de Mayo parade if there are 140 dancers and these represent the 35% is 400.

This information can be known by using the information given about the dancers and a rule of three.

In this case, we know 140 dancers are equal to 35%. This means:

140 = 35 %

 x    = 100 %

x= 140 x 100 = 35

x= 14000 / 35 = 400

This means 400 are the total people in the parade.

Answer:

Step-by-step explanation:

Place : y+x=2 <==> y = 2-x

and now replace y with the x-expression:

2x-(2.x)=-4 <==> 2x-2+x= 4 <==> 3x-2 =4 <==> 3x = 6 --> x = 2

and y = 2-x so y = 2-3 = -1

so the solution is S = {(2; .1)}

[tex]i^{157} = i\\\\i^{315} = -i\\\\i^{102} = -1\\\\i^{76} = 1\\\\[/tex]

=====================================================

Explanation:

By definition, [tex]i = \sqrt{-1}[/tex]

Squaring both sides gets us [tex]i^2 = -1[/tex]

Then multiply both sides by i to get [tex]i^3 = -i[/tex]

Repeat the last step and you should get [tex]i^4 = -i^2 = -(-1) = 1[/tex]

---------------

Notice we have this pattern going on:

[tex]i^0 = 1\\\\i^1 = i\\\\i^2 = -1\\\\i^3 = -i\\\\i^4 = 1\\\\[/tex]

Once we reach i^4, we start the process over again.

It repeats every 4 terms.

This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.

157/4 = 39 remainder 1

That remainder 1 is the exponent of the simplified term

[tex]i^{157} = i^1 = i[/tex]

---------------

Similarly,

315/4 = 78 remainder 3

So [tex]i^{315} = i^3 = -i[/tex]

---------------

102/4 = 25 remainder 2

[tex]i^{102} = i^2 = -1[/tex]

----------------

76/4 = 19 remainder 0

[tex]i^{76} = i^0 = 1[/tex]

Answer: 47.5 cm^2

Step-by-step explanation:

Tony's mistake is that he added the area of the rectangle and triangle. Instead you should subtract the area of the triangle from the rectangle.

1. The area of the rectangle is 5*11 = 55 cm^2

2. The area of the nonshaded triangle is 5*3*(1/2) = 7.5 cm^2

3. The area of the shaded region is the area of the rectangle minus the area of the triangle. This equals 55 - 7.5 cm^2 = 47.5 cm^2

Answer:

1: y=-2x+5

Step-by-step explanation:

When two lines are parallel, the slopes are equivalent.

First, you have to turn 2x+y=7 into standard form.

2x+y=7

y=-2x+7

The slope is -2 so then you find an answer choice with -2 as the slope.

Turn all the answers into standard form first:

2: x+2y=4

2y=-x+4

y=-1/2x+4  Not choice 2 since the slope is -1/2.

3: y-2x=2

y=2x+2 Not choice 3 because the slope is positive 2.

Therefore, choice 1 is parallel to equation 2x+y=7.

Here, We have

We know that,

Therefore,

From the figure, we can conclude that :-

[tex]\bold{ 6x - 5 = 4x + 13 }[/tex]

[tex]\sf{ 6x = 4x + 13 + 5 }[/tex]

[tex]\sf{ 6x - 4x = 13 + 5 }[/tex]

[tex]\sf{ 2x = 18 }[/tex]

[tex]\sf{ x = }{\sf{\dfrac{18}{2}}}[/tex]

[tex]\bold{ x = 9 }[/tex]

Hence, The value of x is 9 .

Length of side QR

[tex]\sf{ = 6x - 5 }[/tex]

[tex]\sf{ = 6(9) - 5 }[/tex]

[tex]\sf{ = 54 - 5 }[/tex]

[tex]\bold{ = 49 }[/tex]

Length of side RS

[tex]\sf{ = 4x + 13 }[/tex]

[tex]\sf{ = 4(9) + 13 }[/tex]

[tex]\sf{ = 36 + 13 }[/tex]

[tex]\bold{ = 49 }[/tex]

From above we can say that,

A rhombus have all its side equal to each other . Therefore, the value of x in the rhombus QRST is 9

Therefore,

6x - 5 = 4x + 13

6x - 4x = 13 + 5

2x = 18

divide both sides by 2

2x / 2 = 18 / 2

x = 9

The total price of a $6.89 item plus 6% sales tax is $7.3043.

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of an item = $6.89

Sales tax = 6%

This means,

Sales tax amount.

= 6/100 x 6.89

= 0.4143

Now,

The total amount of the item.

= 6.89 + 0.4143

= $7.3043

Thus,

The total price plus 6% sales tax is $7.3043.
