Mathematics
1 answer:
Fittoniya [83]3 years ago
8 0

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

What is the answer to, -2x - 13 = -3x - 5​
shtirl [24]

-2x - 13 = -3x - 5​

Step 1: Combine like terms

x's go with x's (-2x and -3x). To do this add 2x to both sides

(-2x + 2x) - 13 = (-3x + 2x) - 5​

(0) - 13 = (-x) - 5​

- 13 = -x - 5​

normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides

(- 13 + 5) = -x + (- 5 +​ 5)

-8 = -x + (0)

-8 = -x

Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)

\frac{-8}{-1} =\frac{-x}{-1}

8 = x

x= 8

Hope this helped!

You have a hat with 5 gray, 3 red, 5 white, and 2 green marbles in it. Find the probability of picking a marble, replacing it, a
nordsb [41]

Answer:

100% chance. I don't know if you mean a certain color. We need to know that color if you want us to help you. But, if you really just want to pick a marble, replace it, and pick another, you will ALWAYS get a marble.

How many whole servings of 3/4 cups are in 3 1/2 cups of ice cream?
Kisachek [45]
Well, what you're going to do is.. turn 3 1/2 into an irregular fraction.

3 = 6/2
we still have the initially 1/2 left so we will add that.
7/2

now we want to change it so that the denominator is equal to 4 so we multiply both top and bottom by 2

14/4

now we divide the 14 by 3 and you will get approximately 4. we will ignore the rest because it asks for whole servings and 3 only goes nicely into 14 4 times
