okay so the little 2 above the 3 is called Exponents and its and easier way of multiplication. So in pemdas there would be parentheses then Exponents ect. so Exponents is after parenthesis.

3x2x2=12

12+ the amount of 1x2

1x2= 2 so

12+2=14

Answer:

11

Step-by-step explanation:

3 squared is 9 and 2×1 is 2

You add last, after doing exponents and multiplying. So last add.

3^2 + 1 × 2

9 + 2

= 11

Generally, if there are parenthesis or brackets or any grouping symbols, do that math first. Then multiply or divide in order from left to right, as you encounter them. Then add or subtract in order from left to right as you encounter them. This is commonly taught as PEMDAS or BODMAS.

You are standing 25 feet from the base of a flagpole.The angle of elevation to the top of the flagpole is 40°.What is the height
liraira [26]

Answer: the height of the flagpole is 21 ft

Step-by-step explanation:

Since the angle of elevation to the top of the flagpole is 40°, a right angle triangle is formed. The height of the flagpole represents the opposite side of the right angle triangle. Your distance from the base of the flagpole represents the adjacent side of the right angle triangle. Therefore, to determine the height of the flagpole, x ,we would apply the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Tan 40 = x/25

x = 25tan40 = 25 × 0.8391

x = 20.98

x = 21.0 ft to the nearest tenth.

What is the length of CD ? In this diagram ABC EDC ?<br> Please help !!!!
n200080 [17]
Answer:
CD = x = 4 units

Explanation:
We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:
\frac{BC}{CD} =  \frac{CA}{CE} =  \frac{AB}{ED}

W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5

Substitute in the above proportionality and solve for x as follows:
\frac{20-x}{x} =  \frac{20}{5} = 4

4x = 20 - x
5x = 20
x = 4

Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units

Hope this helps :)

How much interest will Brian earn on $875 in his savings account after 3 months if the annual interest rate is 5.5%?
eduard

The interest that Brain would receive is $12.03.

<h3>How much interest would Brain receive?</h3>

The interest received is a function of the amount saved, interest time and the length of time the money was saved.

Interest = amount saved x number of months x (annual interest rate / 12)

$875 x 3 x (0.055 / 12) = $12.03
