= 8*8  - 8√10 + 8√10  +√10 *  -√10

= 64 -  8√10 + 8√10 - 10

The 2 middle turns cancel out so we have:

Answers

Answer:

146.96 [tex]m^2[/tex]

Step-by-step explanation:

1. Approach

Divide this figure into two smaller shapes. Calculate the area of these smaller shapes, and then add the results. One can divide this shape into a semi-circle, and a triangle.

2. Area of the triangle

The formula to find the area of a triangle is;

[tex]\frac{base*height}{2}[/tex]

It is given that the base of the triangle is (14m) and the height is (10m). Substitute in these values, and solve for the area,

[tex]\frac{14*10}{2}\\= \frac{140}{2}\\= 70[/tex]

2. Area of the semi-circle

The area of the semi-circle can be found by finding the area of the larger circle, and then divide it by 2, since a semi-circle is half of a circle. The formula for the area of a semi-circle is;

[tex]\frac{(pi)(r^2)}{2}[/tex]

Where (pi) is the constant (3.1415...), (r) represents the radius of the circle, which by definition is half of the diameter. Substitute in the values and solve;

[tex]\frac{(pi)(7)^2}{2}\\= \frac{3.14*49}{2}\\=76.96[/tex]

3. Find the total area;

Now add up the two values for the area of the figures;

Triangle + Semi-circle

= 70 + 76.96

= 146.96

Find the area of the composite figure.

Answers

Answer:

Area = 139.27 m²

Step-by-step explanation:

Area of the composite figure = area of rectangle + area of semicircle

= (L*W) + ½(πr²)

L = 10 m

W = 10 m

r = ½ of 10 = 5 m

Plug in the values

Area = (10*10) + ½(π*5²)

Area = 100 + 39.27

Area = 139.27 m²

Jing is helping the kindergarten teacher put together bags of crayons. Each bag has 4 crayons, and 1/4 of the crayons in each bag are green. What fraction of the crayons in 3 bags is green? A. 3/12 B. 3/4 C. 4/3 D. 12/3

Answers

Answer:

A. 3/12

Step-by-step explanation:

1/4 x 3 for the three different bags and each bag having 1 crayon that's the color green it's 1/4 however due to there being 4 crayons in each bag

the only other answer could be 1/4 when simplified

Answer:

Step-by-step explanation:

1 bag of crayons = 4 crayons = 100% (10/10)

1/4 bag of crayons = 1 crayon = 25% = 1 green crayon per bag

3 bags of crayons = 12 crayons (3 x 4)

if 1 bag has 1 green crayon and there are 3 bags then there are 3 green crayons

Find the slope of a line perpendicular to the equation: 3x – 2y = 6​

Answers

Answer:

3/2x

Step-by-step explanation:

m1xm2=-1
so
y=mx+c
-2y=-3x+6
2y=3x-6
y=3/2x-3

So the gradient of the perpendicular would be

m= -2/3

find the x and y

y=3/2(0)-3
=-3

(0)=3/2x-3
x=2

So
Substitute them all into
y=mx+c

-3=-2/3(2)+c
c=-5/3

So

y=-2/3x-5/3
