HELP ASAP!! WILL MARK BRAINLIST!! A LOT OF POINTSS
Fittoniya [83]

Answer:

Black = 84 cm^2

Blue = 84cm^2

gold = 60.2cm^2

1 ornament = 228.2 cm^2

100 ornaments - 22820 cm^2

Step-by-step explanation:

Black is a rectangle = A = l*w = 7*12 = 84 cm^2

We have 2 blue   This is a triangle  so multiply by 2  the area of a triangle

2 * A = 2(1/2 b*h) = bh = 12*7 = 84 cm^2

We have 2 gold   This is a triangle  so multiply by 2  the area of a triangle

2 * A = 2(1/2 b*h) = bh = 8.6*7 = 60.2 cm^2

The total surface area for one ornament is

84+84+60.2 = 228.2

100 ornaments

Multiply by 100

100 *228.2 = 22820 cm^2

When three times the sum of a number and seven is increased by ten, the result is four. What is the number ?
densk [106]

Answer:

x=9   :))

Step-by-step explanation:

First set up your equation.

"3 times" is multiplication

"THE SUM of A NUMBER and seven" that is parenthesis because of the multiplication before it

"is increased by ten" that is an addition at the end

Now we have 3(x+7)+10=4

Solve your equation!

Distribute the 3 now we have 3x+21+10=4

Add like terms

now it should look like this... 3x+31=4

Subtract 31 from both sides and it looks like...

3x=27

Divide by the x-value

x=9

PLSSSSSS HELPPPP!!!!!Determine the area of the composite figure shown.
katrin2010 [14]

Answer: 26.13yards^2

Step-by-step explanation:

To find the area of the bottom part we can use the diameter.

6 yards. Divide it by half to have the Radius.

Now we use the formula to find the area of a circle which is

A = 3.14*R^2         Pie times radius squared.

A = 3.14*3^2

A = 3.14*9

A = 28.26 Now that we have the area of the circle divide it by 2.

14.13

Now to find the area of an isosceles triangle we use the formula

A = Base * Height Divided by 2.

A = 6*4/2

A = 24/2

A = 12

12 + 14.13 = 26.13
