Step-by-step explanation:

Square= bh

Square= 2×2=

half-circle = 1/2Pi*r×r

half-circle 2 = 1/2Pi*r×r

We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D

There’s two semi-circles with a radius of 2, so it would be 2 x 1/2 x Pi x radius ^2.

Now we need to find the area of the square, which is a^2. The diameter of a circle is double the radius, so we know the sides of the square will equal 4 inches, so 4 x 4.

4 x 4 + 2 x 1/2 x 3.14 x 2^2 should give you your answer. Hope this helps!!

Answer:

292,968

Step-by-step explanation:

As we know,

Sum of a geometric sequence (S) = \frac{a(1-r^{n}) }{(1-r)}

where,

a = first term of sequence,

r = the constant ratio,

n = number of terms in sequence.

So, according to the question,

a = 3,

r = 5,

n = 8.

by substituting the values in the above formula, we get;

⇒ S=\frac{3(1-5^{8}) }{(1-5)}

⇒ 292,968

HELP ME PLEASE :( Will mark as brainlist, only correct answers

Answer:

None of the pairs of expressions are equal

Step-by-step explanation:

• 2n ≠ 2 +n

2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.

•n² ≠ 2n

n²= n ×n

2n= 2 ×n

• 2n² ≠ (2n)²

Note that in the latter, there is a bracket which means that the square applies to both 2 and n.

(2n)²

= (2)² × n²

= (2 ×2)(n²)

= 4n²

Thus, none of the pairs of expressions are equal.

32 students.

3 do none, so we can leave them out.

29 students.

18 + 16 = 34

Use the distributive property to expand 0.05(50 + 40).
AURORKA [14]

Answer:

4.5

Step-by-step explanation:

Here's what I found on google about distributive property:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

distribute the numbers-  0.05(50)+0.05(40)

solve-  0.05*50= 2.5

0.05*40= 2

2.5+2= 4.5

Hope this helps
