Step-by-step explanation:

A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Therefore, the fixed point is called the center of rotation.

What are the angles?

Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'.

A rotation means that the transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point.

So,the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Hence, the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Mac must get 90 on the eighth exam to raise his average to 80%.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.

Given:

Mac has taken seven math exams this year.

His average mark is 78%.

Let x be the required score.

To find the mark to raise his average to 80%:

According to the question,

78(7) + x  = 8(80)

546 + x = 640

x = 640 - 546

x = 90

Therefore, the required mark is 90.

Answer:

6

Step-by-step explanation:

Using the similarity theorem f the triangle

(4+6)/x+9 = 4/x

10/x+9 = 4/x

Cross multiply

10x =4(x+9)

10x = 4x+36

10x-4x = 36

6x = 36

x = 6

Hence the value of x is 6

Step-by-step explanation:

Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:

Rounding to the nearest hundred is 800

Rounding to the nearest ten is 840

Rounding to the nearest one is 838

Rounding to the nearest tenth is 838.3

Rounding to the nearest hundredth is 838.27

Basic Rules of Rounding

When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:

Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.

Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.

If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.

If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

Round to the Nearest Hundred: 3250

Identify the hundreds digit: the 2 in 3250

Identify the next smallest place value: the 5 in 3250

Is that digit greater than or equal to five? Yes, so round up.

Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.

3250 rounded to the nearest hundred is 3300

Round to the Nearest Ten: 323.5

Identify the tens digit: the 2 in 323.5

Identify the next smallest place value: the 3 in 323.5

Is that digit greater than or equal to five? No, so round down.

The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.

323.5 rounded to the nearest ten is 320

Round to the Nearest Ten: 499

Identify the tens digit: the first 9 in 499

Identify the next smallest place value: the second 9 in 499

Is that digit greater than or equal to five? Yes, so round up.

The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.

499 rounded to the nearest ten is 500

Round to the Nearest Tenth: 0.74

Identify the tenths digit: 7 in 0.74

Identify the next smallest place value: the 4 in 0.74

Is that digit greater than or equal to five? No, so round down.

The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.

0.74 rounded to the nearest tenth is 0.7

Round to the Nearest Hundredth: 3.141

Identify the hundredths digit: the 4 in 3.141

Identify the next smallest place value: the second 1 in 3.141

Is that digit greater than or equal to five? No, so round down.

The hundredths digit stays the same at 4. Drop the digits to the right of 4.

3.141 rounded to the nearest hundredth is 3.14

Answer:

Bill paid about 7% sales tax.

Step-by-step explanation:

First, to find the value of 1%, I divided $449.99 by 100, which gave me 4.4999. I then divided the amount paid for tax by the value of 1%. That;s $35.99 ÷ $4.4999 = 7.199439887977596. Obviously, you can't put that in your math homework, plus the question says "about," so you're going to round. Because the first number after the decimal point is less than five, you round down. Therefore, the sales tax is about 7%.

Answer:

Bob is at the top, so he starts at step 9.

Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)

Sue climbs from one step on one step.

Then she if she climbs n times, she will be at the step number:

S(n) = 0 + 1*n

And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:

B(n) = 9 - 2*n

We want to see when they meet, then we need to solve:

S(n) = B(n)

1*n = 9 - 2*n

1*n + 2*n = 9

3*n = 9

n = 9/3 = 3

n = 3.

This means that they meet a the step:

S(3) = 3*1 = 3

B(3) = 9 - 2*3 = 9 - 6 = 3

They meet at the third steep.

Answer:

8 more attackers than defenders

Step-by-step explanation:

36÷18=2

2x11=22

2x7=14

Answer:

8

Step-by-step explanation:

sum the parts of the ratio, 11 + 7 = 18 parts

Divide the number of players by 18 to find the value of one part of the ratio

36 ÷ 18 = 2 players ← value of 1 part of the ratio, then

11 parts = 11 × 2 = 22 ← number of attackers

7 parts = 7 × 2 = 14 ← number of defenders

22 - 14 = 8

There are 8 more attackers than defenders

The midpoint formula is useful here. For midpoint M, we have ...

  M = (C + D)/2

  2M = C + D

  (20, 20) = (15+t, s+3)

  t = 20 -15 = 5

  s = 20 -3 = 17

Check

  (C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK

Answer:

392.35

Step-by-step explanation:

35% + 35% is 70 % so 133 +133 is 70 % witch is 269.

next we need to figure out 30 percent and they give us 35 % so. you add to zeros to 30 because percentage is out of 100 and there are 2 zeros in 100. so it look like this

3000 ÷ 133 = 22.56 is 30% of 133

70% + 30% = 100%

269 + 22.56= 291.56 is your answer
