Answer:

30 inches squared

Step-by-step explanation:

The formula for a RIGHT triangle is:

[tex]A= \frac{ab}{2}[/tex]

We are given..

Therefore...

[tex]A = \frac{5(12)}{2}[/tex]

[tex]A=\frac{60}{2}[/tex]

[tex]A = 30[/tex]

Answer:

- x+2y= - 4

2y= - x - 4

Y=x-4/2

Y=x-2

Now, 2nd equation

4x+3y=5

4x+3.x-2=5

4x+3x-2=5

7x-2=5

7x=5+2

x=5+2/7

x=7/7

x=1

Now, continue with 1st equation

y=x-2

y=1-2

y=1

Therefore x=1

And

y=1

Answer: B

Because 3 kilograms = 3,000 and 3,000 kilograms = 3,000 grams

Answer:

w ≤ 2200

Step-by-step explanation:

If a lift can lift a maximum weight of 2200pounds, this means that the lift can not life a weight greater than 2200pounds. For the expression needed, the inequality sign to use will be a less than or equal to sign( ≤ ).

Hence the requires inequality expression will be w ≤ 2200

Answer: 19 ¹/₂ cups of purple paint

Step-by-step explanation:

First find out the quantity of purple pain that she has:

= 3/4 + 3/4

= 6/4 cups of paint.

If she mixes 13 batches, the cups of purple paint she will have will be the original number multiplied by 13

= 6/4 * 13

= 78/4

= 19 ¹/₂ cups of purple paint

Answer:

216 :)

Step-by-step explanation:

There are five sides in total. To find the total surface area we have to find the area of each side.

Let's start off easy with the rectangle at the base. The width and length are 7 and 6, which gives us an area of 42.

The rectangle with dimensions of 8 as the length and 7 as the width gives us an area of 56.

The rectangle with a length of 10 and a width of 7 gives us 70 as an area.

The two triangles are congruent, so all we have to do is find the area of one and multiply it by two. The formula for an area of a triangle is 1/2(bxh)-or the two legs multiplied by each other and then divided by 2. The length of one of the legs is 8, and the other is 6. That gives us 48, which we will then divide by 2 to give us a total area of 24. Now we have to multiply that by two because there are two triangle sides on this figure and they are congruent. That gives us a product of 48.

Now we add up all the areas of each side:

42 + 56 + 70 + 48 = 216

Answer:

1240

Step-by-step explanation:

Number of boys to a girl is

x:y= 11:9

9x= 11y

There are 124 more boys in the schooll than girls

x= 124+y

Substitute 124+y for x

9(124+y)= 11y

1116+9y= 11y

1116= 11y-9y

1116= 2y

y= 1116/2

y= 558

Number of girls is 558

The number of boys can be calculated as follows

= 558+124

= 682

Hence the total number of students is

= 682+558

= 1240

Answer:

81.51

Step-by-step explanation:

So first you will want to take the percentage of the $78.00.

What we do is multiply 78.00 by 0.045

which is 4.5%

You then get $3.51

Add that to the $78.00:

78.00 + 3.51

= $81.51

40

Answer:

[tex]x^{2} - 2x + y^{2} - 8y = 8[/tex]

Step-by-step explanation:

Standard form for a circle is:

[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex]      (h, k) is the center    r is the radius

[tex](x - 1)^{2} + (y - 4)^{2} = 5^{2} \\x^{2} - 2x + 1 +y^{2} - 8y + 16 = 25\\x^{2} - 2x + y^{2} - 8y = 8[/tex][tex]x^{2} - 2x + y^{2} - 8y = 8[/tex]

Answer:

z > -2

Step-by-step explanation:

7 + z > 5

subtract 7 from each side of the equation:

z > -2

The inequality for the given phrase is z+7>5.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given phrase is "7 plus a number z is more than 5".

Here, 7 plus a number z is

7+z

The obtained sum is more than 5.

That, is z+7>5

Subtract 7 on both the sides of an inequality, we get

z+7-7>5-7

z>-2

Therefore, the inequality is z+7>5.
