Answer:
Sammy left a tip of $1.34
Step-by-step explanation:
Convert 15% into a decimal by dividing by 100%
15% ÷ 100% = 0.15
Multiply it to the meal cost
$8.95 × 0.15 = $1.3425
Rounding to the nearest cent, Sammy should leave a tip of $1.34.
I hope this helps you!

The area of the figure is ____ square units.
Answer: 132 square units
Step-by-step explanation:
Area of a trapezoid:
a = top base; b = bottom base; h = height
[tex]A=\frac{a+b}{2}+h[/tex]
Find the bases and the height:
b: 21 (given)
h: 8 (given)
a: find from the bottom
need to find the only not given value by subtracting the values we know. (this might be a little confusing but I think it'll be easier if you look at the original picture)
21 - 9 - 3 = 9
add the new number with the given length of the top base
9 + 3 = 12
Substitute the values into the equation:
[tex]A=\frac{a+b}{2}+h\\[/tex]
[tex]A=\frac{12+21}{2}+8[/tex]
(I used a calculator to find it out)
Area = 132 square units

The graph of a quadratic function has x-intercepts at x = 3 and x = -5. It passes through the point
(1,-12). Determine the equaiton of the quadratic function.
The quadratic function that has x-intercepts at x = 3, and x = -5 that
passes through the point (1, -12) is f(x) = x² + 2·x - 15.
How can the required quadratic function be found?The intercepts of the graph of the quadratic function are x = 3 and x = -5
The point through which graph passes is (1, -12)
Required:
The equation of the quadratic function.
Solution:
Given that the intercepts are x = 3, and x = -5, we have;
x = 3, and x = -5 are the zeros of the quadratic function, which gives;
Factors of the quadratic function are; (x - 3) and (x + 5)
From which we have;
(x - 3) × (x + 5) = x² + 2·x - 15 is a factor of the quadratic function
When x = 1, we have;
1² + 2 × 1 - 15 = -12
Therefore, the point (1, -12) is a point on the quadratic function x² + 2·x -
15 that has intercepts at x = 3, and x = -5
The equation of the quadratic function is therefore;

9 in the tens place means 90, and 9 in the thousands means 9000.
In Gale's number, 9 is in the hundreths place.
In Luca's number, 9 is in the ones place.
9 in the hundreths means 9/100.

28 is 160% of what number?
Answer:
28 is 160% of 17.5
Step-by-step explanation:
The value of number is, 17.5
That is, 28 is 160% of 17.5.
We have to give that,
To find 28 is 160% of which number.
Let us assume that,
A number = x
Hence, We can write as,
28 = 160% of x
Solve for x,
28 = 160/100 × x
Multiply by 100,
28 × 100 = 160x
2800 = 160x
160x = 2800
Divide into both sides by 160,
x = 2800/160
x = 280/16
x = 140/8
x = 70/4
x = 35/2
x = 17.5
Hence, The solution of the number is, 17.5

Rihanna wants to find the distance, AB, across a river. She starts at point B and walks along the edge of the river 215 ft and marks point C. Then she walks 25 ft further and marks point D. She turns 85° and walks until her final location and marks point E. Point E, point A, and point C are collinear.
Answer:
She used the AA theorem because the two interior angles B and D are equal to 85 degrees. ABC and EDC are equal because they are vertically opposite angles.
ABC=EDC
ABC~EDC By AA criterion of similarity
AB/ED = AC/EC Because the corresponding sides of similar triangles are proportional.
Suppose (DE) =105 ft. Calculate the distance of (AB) . Show your work. Don’t forget to label your answer.
The answer is AB= 903
105=DE 25=DC 215=CB 903=AB
105/25= 4.2

It cost Riley 6.00 dollars to send 120 text messages how much does each text cost to send
Answer:
Each text costs 5 cents ($0.05)
Step-by-step explanations:
To find the cost of one text, divide the $6.00 by 120.
You will come up with 0.05, meaning the correct answer is 5 cents
The cost of each text message is 0.05 dollar.
What is Unitary Method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cost of 120 text messages = $6
So, price to pay for 1 text message is
=6/120
=1/20
= 0.05 dollar
Hence, the cost of each text message is 0.05 dollar.

The vertex angle of an isosceles triangle measures 42°. A base angle in the triangle has a measure given by (2x + 3)°. What is the value of x? What is the measure of each base angle?
Answer:
x = 33base angles: 69°Step-by-step explanation:
The sum of angles in a triangle is 180°. In an isosceles triangle, the base angles are congruent.
For this, it is easiest to find the base angles first. If we let b represent the measure of one of them, the sum of angles is ...
2b +42 = 180
b +21 = 90 . . . . . . divide by 2
b = 69 . . . . . . . subtract 21
The measure of the base angles is 69°.
__
Then we can find the value of x from its relation to the base angle measure:
(2x +3)° = 69°
2x = 66 . . . . . . . . . divide by °, subtract 3
x = 33 . . . . . . . . divide by 2
The value of x is 33.
Answer:
x = 33
each base angle measures 69°

Step-by-step explanation:
you mean, solve the inequality ...
it works the same way as with equations.
6x >= 24
x >= 4 (after dividing both sides by 6)
the only thing different is when you multiply (or divide) both sides by a negative number. then you have to turn the inequality sign around (< becomes >, <= becomes >=).
but other than that it is all as with regular equations.

Answer:
7.2
Step-by-step explanation:
14 = c
12= b
√(c² - b²)
12 x 12 = 144
14 x 14 = 196
196-144 = 52
√(52) = 7.21110255093
Answer:
x ≈ 7.2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 14²
x² + 144 = 196 ( subtract 144 from both sides )
x² = 52 ( take square root of both sides )
x = [tex]\sqrt{52}[/tex] ≈ 7.2 ( to the nearest tenth )

Answer:
YES
Step-by-step explanation:
Why is the classmate correct?
The reason why the classmate is correct is that everything can turn 360 degrees. This means that a square, has to turn 360 degrees, and it does that by doing 90x4. This means that it has 90-degree angles, which turn 4 times. And that makes 360. That's how this is also correct. Because this classmate turned a figure 270 degrees clockwise, and also, 360-270=90, which means that turning that figure 90 degrees counter-clockwise will make it in that same position.
To check whether this is right or not, take an object, probably like a book. Then turn it 90 degrees to counter-clockwise, and note down the position, that the front of the book is now facing left, and the back of the book is now facing right. Then, turn it back to normal position, (back of the book facing you), then, turn it 3 times 90 degrees towards Clockwise, in that way, you can see, that the book turns in the same way it did when you did 90 degrees counter-clockwise!

In order to win her race, Millie doubles her running speed every minute. If she starts out running at 2 miles per hour, how fast will she be running after 3 minutes?
Answer: 4.2 kilometers after 3 minutes bc its 1.0729 kilometers after 1 minute. then it doubles every minute .
Step-by-step explanation: speed= distance divided by time method
The speed is the distance covered by an object at a particular time. Millie speed after three minutes will be equal to 16 miles per hour.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given that Millie doubles her running speed every minute. Also, her starting speed is 2 miles per hour. Therefore, her speed in different time period can be written as,
Speed after 1 min = 2 × 2 miles per hour
= 4 miles per hour
Speed after 2 min = 2 × 4 miles per hour
= 8 miles per hour
Speed after 3 min = 2 × 8 miles per hour
= 16 miles per hour
Hence, Millie speed after three minutes will be equal to 16 miles per hour.
