Answer:
56.52mm²
Step-by-step explanation:
Based on observation, sum of diameters of small circles = diameter of the big circle.
In question, diameter of big circle = 12 mm.
And radius of big circle = 12mm/2 = 6mm
Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.
=> 2a + 2a = 12mm
=> 4a = 12mm
=> a = 3mm
=> radius of each small circle = 3mm
Area of big circle = πr²
= (3.14)(6mm)²
= 113.04 mm²
Area covered by 2 small circles is: 2 * area of 1 one circle.
=> 2 * π(3mm)² = 18π mm²
=> 56.52 mm²
Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²

Give the coordinates of each vertex (D, E, F) and explain how you found the coordinates using transformation rules.
Answers
Step-by-step explanation:
We have that the vertices of triangle ABC are:
A(4, 2)
B(7, 9)
C(7, 2)
First, we are reflecting over the y axis, which makes (x,y) map onto (-x, y). This gives us:
A'(-4, 2)
B'(-7, 9)
C'(-7, 2)
Then, we translate 5 units down, meaning we subtract 5 from each of the y coordinates. This gives us a final answer of:
D(-4, -3)
E(-7, 4)
F(-7, -3)

Find the area; reduce to lowest terms: Length: 3 2/3 feet; Width: 1/4 feet
Answers
Answer:
11/12 square feet
Step-by-step explanation:
The area is the product of length and width. Multiplication of mixed numbers is often easily done by converting to improper fractions.
A = LW
A = (3 2/3 ft)(1/4 ft)
A = (11/3)(1/4) ft² = 11/12 ft²
The area is 11/12 square feet.

if 4 friends eat 4 cakes in 4 days then how many cakes will 10 friends eat in 10 days
Answers
Answer:
If four friends can eat four cakes in four days, then four friends will eat an average of one cake per day, so each friend will be able to eat 1/4 of a cake per day.
So 10 friends will eat 10/4 of cake per day, or two and a half cakes per day, so they will eat 2,5 * 10 = 25 (twenty-five) cakes per 10 days, assuming they will eat at the same rate

Clare’s aunt used a credit card to pay $42 for an outfit. Six weeks later, the credit card company charged her 2% interest.
a. How much is the 2% interest?
b. How much will Clare’s aunt have to pay in total?
Answers
Answer:
0.84$ and 42.82$
Step-by-step explanation:
2% is equivalent to 2/100
So, 42$ x [tex]\frac{2}{100}[/tex] = 84/100 = 0.84$ (the 2% interest)
And the total the aunt has to pay equals to = 42$ + 0.84$ =42.84$

Laurie saw some stray cats in her backyard. She put out some water and a bowl with 3 cups of food. The cats drank all the water and ate half of the food. How many ounces of food did the cats eat?
Answers
Answer:
12
Step-by-step explanation:
1 cup = 8 ounces.
In total, there are 3 cups of food.
So, we do 3 × 8 which would equal 24.
24 ÷ 2 = 12.
12 is half of all the food Laurie gave to the stray cats
Therefore, 12 is the correct answer.

Answers
"First, you have 35 total pens in the box. 15 are green. to find how many red pens you need to find the difference between 35 and 15 to get how many red pens there are. (35-15= 20) Therefore, there are 20 red pens. The ratio needs to be green pens to red pens. So, there is 15 green and 20 red ( 15/20 or 15:20) Simplify that by 5 and you get 3/4 or 3:4. "

Answers
Answer:
La temperatura del aire a una altitud de 15000 metros sobre el nivel del mar es -66 ºF.
Step-by-step explanation:
Dada la relación de linealidad, construimos una función lineal de la temperatura del aire en función de la altitud con respecto al nivel del mar, la cual es:
[tex]T(h) = T_{L} + \frac{T_{H}-T_{L}}{h_{H}-h_{L}} \cdot h[/tex], [tex]0\,m \leq h \leq 20000\,m[/tex] (Eq. 1)
Donde:
[tex]T_{L}[/tex] - Temperatura del aire a nivel del mar, medida en grados Fahrenheit.
[tex]T_{H}[/tex] - Temperatura del aire a determinada altitud, medida en grados Fahrenheit.
[tex]h_{L}[/tex] - Altura del nivel del mar, medida en metros.
[tex]h_{H}[/tex] - Altura determinada, medida en metros.
[tex]h[/tex] - Altitud con respecto al nivel del mar, medida en metros.
[tex]T(h)[/tex] - Temperatura del aire a una altitud con respecto al nivel del mar, medida en grados Fahrenheit.
Si sabemos que [tex]T_{L} = 60\,^{\circ}F[/tex], [tex]T_{H} = 18\,^{\circ}F[/tex], [tex]h_{L} = 0\,m[/tex], [tex]h_{H} = 5000\,m[/tex] y [tex]h = 15000\,m[/tex], la temperatura del aire a esa altitud es:
[tex]T(15000\,m) = 60\,^{\circ}F + \frac{18\,^{\circ}F-60\,^{\circ}F}{5000\,m-0\,m} \times 15000\,m[/tex]
[tex]T(15000\,m) = -66\,^{\circ}F[/tex]
La temperatura del aire a una altitud de 15000 metros sobre el nivel del mar es -66 ºF.
