What is the percent for 138

It has 0 lines of symmetry because we cannot reflect any portion of itself over the line to land on another portion. For example, we cannot draw a vertical line through the center and reflect the right half over to the left side. The arrow doesn't match or line up properly.

It does however have rotational symmetry. The angle of rotation is 360/3 = 120 degrees. We can rotate the figure 120 degrees, either clockwise or counterclockwise, and the resulting figure will be 100% identical to the original figure. In short: after the rotation, no change has been made. This is because the arrows are effectively going in a circle. Applying a rotation to a circle does not change the circle overall.

Answer:

x = -11/7

x = 11/7

Step-by-step explanation:

49x² - 121

Factor

(7x + 11)(7x - 11)

roots

x = -11/7

x = 11/7

Answer:

Hello! answer: x = 60

Step-by-step explanation:

This is a complementary angle so it will add up to 90 degrees! here is a demonstration picture for how I solved it! Hope that helps!

Answer:

complementary and the angle is 60

hope this helps

Answer:

16

Step-by-step explanation:

Step 1. add up all the numbers. In this case when you add up your numbers you get 112.

Step 2. Divide your answer (112) by the the amount of numbers given (which in your case is 7)

Step 3. Answer did not need to be rounded.

Best of luck my friend! Hope I helped.

Answer:

If y(x-y)^2=x, then int1/(x-3y)dx is equal to (A) 1/3log{(x-y)^2+1} (B) 1/4log{(x-y)^2-1} (C) 1/2log{(x-y)^2-1} (D) 1/6 log{(x^2-y^2-1}

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

First up, chill a bit xd

So hot dog = x

Drink = y

2 hot dogs = 2x

2 drinks = 2y

2x + 2y = 4.75

3 hot dogs = 3x

1 drink = y

3x + y = 7.75

Answer:

b = 6.7 cm

Step-by-step explanation:

Here, we want to find the value of b

to do this, we are going to use the law of sines

And this law is that the ratio of the measure of a side and the sine of the angle facing the side is constant for all the sides of a triangle

Thus, we have it that;

a/sin A = b/sin B = c/sin C

Before we proceed, we need the measure of the last angle

That would be 189 minus the sum of the two given angles

we have this as;

180 - (82 + 55) = 43

Thus;

b/sin 43 = 8/sin 55

b = 8 sin 43/sin 55

b = 6.7 cm

EDGE 2021

Answer:

Without going to tables:

Suppose 1$ originally deposited

After 18 years using A (1 + i)^18 = 1.04^18 = 2.0258 $

Interest earned on the 1$ was 1.0258

How many $ deposited to earn $72

72 / 1.0258 = 70.18

So the original deposit was 70.188

Check:

70.188 * (1.04)^18 = 142.19 Collected at 18

If 70.18 was initially deposited then

142.19 - 70.18 = 72  is the interest earned

Answer:

See explanation.

Step-by-step explanation:

Aim of experiment:

To discover the amount of time (average amount of time) that 7th grade students spend on homework each week.

Name of researcher:

Mary.

Requirements for the experiment:

- knowledge of the number of hours that some or all of the students spend on homework each week

- knowledge of the total number of 7th grade students (population statistics)

The issue or problem with this question is that it doesn't say what Mary found out after her research. There are no result statistics from the experiment! Mary surveyed 20 students out of the 164. Her findings will/can be used to infer about the population. Those findings are absent here, hence the question can't be solved.
