Can someone please help me find the area of the figure.

Answers

Answer:

45.4

Step-by-step explanation:

→ Area of the polygon = Area of Square + Area of semi-circle

Area of square :

→ Area of square = Side × Side

→ Area of square = 6 m × 6 m

→ Area of square = 36 m [tex] \sf ^2[/tex]

Area of semi-circle :

→ Area of semi-circle = [tex] \sf \dfrac{Area \: of \: circle}{2} [/tex]

→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]

→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]

→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times (3)^2}{2} [/tex]

→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times 3 \times 3}{2} [/tex]

→ Area of semi-circle = [tex] \sf \dfrac{28.26}{2} [/tex]

→ Area of semi-circle = 14.13 m[tex] \sf ^2[/tex]

⇒ Area of shape = ( 36 + 14.13 ) m[tex] \sf ^2[/tex]

⇒ Area of shape = 50.13 m[tex] \sf ^2[/tex]

Therefore,

Area of the shape is 50.13 m[tex] \sf ^2[/tex].

The formula for finding the volume of a rectangular prism is V = Bh. A rectangular prism with dimensions _________ will have a volume of 150 cubic units.

Answers

Answer: 10 * 5 * 3

Step-by-step explanation:

We want to find a base and a height that will multiply together to equal 150 [tex]units^{3}[/tex].

One solution is a [tex]B = 50 units^{3}[/tex] and [tex]h = 3 units^{3}[/tex].

Thus we need a length and width of the base that will multiply together to equal 50 [tex]units^{2}[/tex]. One solution is 10 units * 5 units.

Putting this all together, we have a solution of 10 units * 5 units * 3 units, which will have volume of 150 cubic units.

Answer:

  (47xy)/(6√3)

Step-by-step explanation:

A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.

A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.

A quotient is formed when a first value is divided by a second value.

Here is the quotient of our variable term and our constant:

Pls help me ASAP!!! Tickets for a concert cost $7.50 for students and $15 for adults. 150 ticket are sold, and $1612.50 is collected. How many student tickets were sold? How many adult tickets?

Answers

Answer: 85 student tickets, 65 adult tickets.
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65

x=150-65
x=85

Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?

GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO

Answers

Answer: hope this helps ♡

Lily had 16 stamps and Mackenzie had 20 stamps.

Step-by-step explanation:

Lily gives 4 stamps to Mackenzie

(Mackenzie)     m + 4 = 2(L - 4)      (Lily)

Solve for Lily:

m + 4 = 2L - 8

m + 4 + 8 = 2L

(m + 12) ÷ 2 = 2L ÷ 2

(m + 12) ÷ 2 = L

L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)

Mackenzie gives 4 stamps to Lily

(Mackenzie)     m - 4 = L + 4      (Lily)

m - 4 = ((m + 12) ÷ 2) + 4

m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4

2m - 4 + 4 = (m + 12) + 4 + 4

2m - m = (m - m + 12) + 8

m = 12 + 8

m = 20 (we will substitute this value of m in the next equation)

L = (m + 12) ÷ 2

L = (20 + 12) ÷ 2

L = 32 ÷ 2

L = 16

An artist mixes paint to make new colors.
She uses 1/3 cup of red paint and 1/3 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available, how many batches of orange paint can she make?
Enter your answer in the box.

Answers

Answer:

6 batches of orange paint can be made.

Step-by-step explanation:

2 cups of red paint can go to 6 cups of 1/3 a batch of red paint, and 3 cups of yellow paint can go to 9 cups of 1/3 a batch of yellow paint.

She then combines 6 cups of 1/3 cups of red paint with 6 cups of 1/3 cups of yellow paint. The reason it is not 9 is that she doesn't have 3 extra 1/3 cups of red paint.

6 batches of orange paint can be made, with 3 extra 1/3 cups of yellow paint.
