Answer:
19%
Step-by-step explanation:
Percentage tip = (Tip/Dinner cost) x 100
Percentage tip = ($5.32/$28) x 100
Percentage tip = 0.19 x 100
Percentage tip = 19%

3√81
3√-64
Answer:
Sure, I'd be happy to help you with these problems!
Simplifying square root expressions:
√121 = 11
The square root of 121 is a rational number because it can be expressed as a ratio of two integers (11/1).
√48 = √(16*3) = √16 * √3 = 4√3
The square root of 48 is an irrational number because it cannot be expressed as a ratio of two integers.
Simplifying cube root expressions:
3√81 = 3√(3^4) = 33 = 9
The cube root of 81 is a rational number because it can be expressed as a ratio of two integers (9/1).
3√(-64) = 3√(-444) = 34√(-4) = 12i√2
The cube root of -64 is an irrational number because it cannot be expressed as a ratio of two integers. However, it can be expressed as a product of a rational number (4) and an imaginary number (i√2), where i is the imaginary unit (i.e., i^2 = -1). Therefore, the simplified form of this expression is an imaginary number.
1. √121:
To simplify this expression, we need to find the square root of 121. The square root of 121 is 11, since 11 * 11 = 121. Therefore, the simplified form of √121 is 11.
Since 11 is a whole number, it is considered a rational number.
2. √48:
To simplify this expression, we need to find the square root of 48. We can simplify it by factoring 48 into its prime factors: 48 = 2 * 2 * 2 * 2 * 3.
Taking out pairs of identical prime factors, we get √48 = √(2 * 2 * 2 * 2 * 3) = 2 * 2 * √3 = 4√3.
The simplified form of √48 is 4√3.
Since 4√3 cannot be expressed as a fraction, it is considered an irrational number.
Now let's simplify each cube root expression and describe the simplified form as rational or irrational.
3. 3√81:
To simplify this expression, we need to find the cube root of 81. The cube root of 81 is 4, since 4 * 4 * 4 = 81. Therefore, the simplified form of 3√81 is 4.
Since 4 is a whole number, it is considered a rational number.
4. 3√-64:
To simplify this expression, we need to find the cube root of -64. The cube root of -64 is -4, since -4 * -4 * -4 = -64. Therefore, the simplified form of 3√-64 is -4.
Since -4 is a whole number, it is considered a rational number.
In summary:
- √121 simplifies to 11, which is a rational number.
- √48 simplifies to 4√3, which is an irrational number.
- 3√81 simplifies to 4, which is a rational number.
- 3√-64 simplifies to -4, which is a rational number.

Option 1 : 1/20 × 200
Option 3 : 10
Above options are only correct for the given question.
First of all, let us calculate the value of 5% of 200
⇒ 5/100 × 200 = 1/20 × 200 = 10
Now, check each option whether they give the same value i.e., 10.
Option 1 : 1/20 × 200
⇒ 1/20 × 200 = 10
Hence, the above expression is equivalent to 5% of 200.
Option 2 : 1/5 × 200
⇒ 1/5 × 200 = 40
Hence, the above expression is not equivalent to 5% of 200.
Option 3 : 1/2 ÷ 200
⇒ 1/2 ÷ 200 = (1/2) × (1/200) = 1/400
Hence, the above expression is not equivalent to 5% of 200.
Option 4 : 10
This option is correct as the value of 5% of 200 is 10.
Option 5 : 5
This option is incorrect as the value of given expression is 10.

The population of a city decreases by 1.7% per year. If this year's population is 192,000, what will next year's population be, to the nearest individual?
Answer: 188,736
Step-by-step explanation:
The original amount is 192,000. Every year, the population decreases by 1.7%, which means that the population is 98.3% of last year's.
0.983 * 192,000 = 188,736

How many degrees is angle 7?
Answer:
42°
Step-by-step explanation:
This is defined as a transversal in geometry, where one line intersects two straight lines.
It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.
∠4 ≅ ∠42 based on the alternate interior angles theorem.
∠4 ≅ ∠7 based on the vertical angles theorem.
Therefore, ∠42 ≅ ∠7 based on CPCTC.
Therefore,
m∠7 = 42°.

The variables y and x have a proportional relationship, and y = 7 when x = 2.
What is the value of y when x = 5?
Enter your answer as a decimal in the box.
y = ___
Answer:
17.5
Step-by-step explanation:
x=2
y=7
when y by x, then multiple y by 5.
7/2= 3.5
3.5×5= 17.5
you can also do 7x2 which would give you 14 and then divide 7 by 2 to get 3.5, and add the two together, so 14+3.5=17.

Mrs. Gomez is buying a triangular table for the corner of her classroom. The side lengths of the table are 5 feet, 3 feet, and 2 feet
Is this a triangular table a right triangle?
Answer:
The answer to your problem is, D. Yes, because 2 + 3 = 5.
Step-by-step explanation:
Refer to the converse of the pythagorean theorem. We need to have both sides equal to each other to have a right triangle.
So we need to have:
[tex]a^{2} + b^{2} = c^{2}[/tex]
We would need to fill out the problem and replace A, B, and C. Which leads to either being B or D
The longest side is the hypotenuse and the value of c.
Thus the answer to our problem is, D. Yes, because 2 + 3 = 5

What is the area of a right triangle with a height of 8.9cm and a base of 14.3cm?
Answer:
ar of triangke is 1 /2 base*height
so
ar = 1/2 * 8.9*14.3
ans = 63.63 sq cm
Answer: 63.63cm
Step-by-step explanation: To find the area for a triangle, the formula is A=L*W divided by 2. So you want to do A=14.3*8.9/2= 63.63500 (63.63).

Find the measure of ∠YOZ by answering the questions.
1. Find the measure of ∠WOV. Which angle relationship did you use? (3 points)
2. Now find the measure of ∠YOZ. Which angle relationship did you use? (3 points)
3. Check your answer by using another strategy to find the measure of ∠YOZ. Describe your strategy, and show that it gives the same measure for ∠YOZ. (4 points)
Answer:1. The measure of ∠WOV is 60°. You would use complementary angles that are adjacent (∠WOV, and ∠XOW)
2. The measure of ∠YOZ is 60°. You would use the vertical angles that are non-adjacent (∠WOV, and ∠YOZ). These two angles are congruent so they would have the same measure. These angles combined also create supplementary angles
3. Another way to find the measure of ∠YOZ would be to make/write an equation and solve for x. For example, (3x+30)°=60°. x would equal 10 because 10x3=30+30=60°
Step-by-step explanation:
1. Since a complementary angle would equal 90°, simply subtract 30° from 90° resulting in 60°.
2. Because vertical angles are congruent and (∠WOV, and ∠YOZ) are a pair of them, they equal the same as each other so they're both 60°.
3. You can make any equation with x included as long as it equals 60° mine was just an example you can make your own like 10x+10=60 or 4x+20=60. Also to create your equation you also need to use the angle fact of the vertical angles
Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
