Henri's bill at a restaurant is $19.62. He wants to leave a tip of 20%, or , of the bill. To find the exact amount of the tip, he should multiply the bill by .20. A good estimate for the amount of the tip is ____. A good estimate for the total bill, including the tip, is ____.
Answer:
The tip is $3.92. The total bill is $23.54.
Step-by-step explanation:
I simply used a calculator to find the answer. It's just basic multiplication for the tip and addition for the total bill.
Answer:
1st blank = $4
2nd blank = $24
Step-by-step explanation:
Henri's bill at a restaurant is $19.62. He wants to leave a tip of 20%
Estimated round off of $19.62 is $20.
Estimations are made for easy calculations in mind, this is why we round to nearest 0.
So, 20% of $20 is :
[tex]0.20\times20=4[/tex] dollars
And the total bill, including the tip is estimated to be :
= [tex]20+4=24[/tex] dollars
The temperature decreased at a constant rate for 12 hours. If the temperature dropped a total of 18 degress over thoes 12 hours, what was the hourly change in temperature?
1.5 degrees per hour
There was a decrease of 1.5 degrees per hour.
What is unit rate?A unit rate means a rate for one of something.
Given that, The temperature decreased at a constant rate for 12 hours, the temperature dropped a total of 18 degrees over those 12 hours,
In 12 h = -18 degrees
In 1 h = 18/12 = 1.5 degrees.

Mr Klinker is 35 and his daughter is 10. In how many years will Mr.Klinker be twice as old as his daughter? Right an algebriac equation and solve.
Final answer:
Mr.Klinker will be twice as old as his daughter in 15 years.
Explanation:
To find the number of years in which Mr. Klinker will be twice as old as his daughter, we can set up an equation:
Let x be the number of years in the future.
Mr. Klinker's age: 35 + x
Daughter's age: 10 + x
According to the problem, Mr. Klinker will be twice as old as his daughter, so we can write the equation:
35 + x = 2(10 + x)
Now, let's solve for x:
35 + x = 20 + 2x
Move the 2x to the left side:
x - 2x = 20 - 35
-x = -15
Divide both sides by -1:
x = 15
Therefore, Mr. Klinker will be twice as old as his daughter in 15 years.
if f(x)=3/x+2- sqrt x-3 f(7)=?
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824
Answer:
f(7)=-3.217
Step-by-step explanation:
We are given that [tex]f(x)=\frac{3}{x}-\sqrtx-3[/tex]
We have to find the value of f(7).
Substitute the value of x=7
Then, we get
[tex]f(7)=\frac{3}{7}+2-\sqrt7-3=\frac{3}{7}-1-\sqrt7[/tex]
[tex]f(7)=\frac{3-7}{7}-\sqrt7=-\frac{4}{3}-\sqrt7[/tex]
[tex]f(7)=-\frac{4}{7}-2.646[/tex]
Because [tex]\sqrt7=2.646[/tex]
[tex]f(7)=-\frac{4+18.522}{7}=-\frac{22.522}{7}[/tex]
[tex]f(7)=-3.217[/tex]
Hence, f(7)=-3.217
Convert 6.7 hours to hours and minutes. A) 6 hours and 30 minutes B) 6 hours and 36 minutes C) 6 hours and 42 minutes D) 6 hours and 48 minutes E) 6 hours and 54 minutes
The answer would be C because 6.7 hours is converted to 402 minutes. In 6 hours, there are 360 minutes. 402-360=42, therefore 6.7 hours is equal to 6 hours and 42 minutes.
Final answer:
6.7 hours is equal to 6 hours and 42 minutes. The conversion is done by multiplying the decimal part of the hour by 60 to get the minutes.
Explanation:
To convert 6.7 hours to hours and minutes, first, note that the integer part of the number represents the hours. Therefore, we have 6 hours. The decimal part (0.7) represents the fraction of the hour. Since there are 60 minutes in one hour, we convert the fraction of the hour to minutes.
To do this, we multiply 0.7 by 60:
0.7 hours * 60 minutes/hour = 42 minutes
So, 6.7 hours is equal to 6 hours and 42 minutes, which corresponds to the answer C) 6 hours and 42 minutes.

write 2.96 as a mixed number or fraction in simplest form show your work
To write 2.96 as a mixed number or fraction in simplest form, we divide the decimal part by 100, convert it to a fraction, and simplify it. The final answer is 2 24/25.
Explanation:To write 2.96 as a mixed number or fraction in simplest form, we first need to understand that 2.96 is a decimal number. The whole number part is 2 and the decimal part is 0.96. To convert the decimal part to a fraction, we take the decimal part as the numerator and 100 as the denominator. So, 0.96 becomes 96/100. Now, we can write the mixed number as 2 96/100. To simplify this fraction, we divide both the numerator and the denominator by their greatest common factor, which is 4. Dividing 96 by 4 gives us 24, and dividing 100 by 4 gives us 25. So, the simplest form of 2 96/100 is 2 24/25.

The Quotient 250 divided by 5/8 tells about how far a sloth may move in one hour How far can a sloth go in 90 minutes?
Given condition is:
A sloth moves in one hour = [tex]\frac{250}{5/8}[/tex]
[tex]\frac{5}{8}=0.625[/tex]
So, a sloth moves in one hour = [tex]\frac{250}{0.625}=400 units[/tex]
Hence, in 60 minutes a sloth moves = 400
In 1 minute sloth will move = [tex]\frac{400}{60}[/tex]
In 90 minutes it will move = [tex]\frac{400}{60}\times90=600[/tex]
The answer is 600 units.
Answer:
A sloth can move 600 units in 90 minutes.
Step-by-step explanation:
The problem says that if you divide 250 in [tex]\frac{5}{8}[/tex] you obtain how far a sloth move in one hour, then:
[tex]250:\frac{5}{8}=\frac{250.8}{5}= \frac{2000}{5}=400[/tex]
A sloth moves 400 units in one hour (60 minutes).
We can use a rule of three,
400 units ⇒ 60 minutes
x ⇒ 90 minutes
[tex]x=\frac{90.400}{60} \\\\x=\frac{36000}{60}\\\\x=600[/tex]
A sloth can move 600 units in 90 minutes.

C.
the initial height of ball when the player releases it
D.
the total time the ball spends in the air
Answer:
the initial height of ball when the player releases it
Step-by-step explanation:
A basketball player shoots a free throw in a game. The quadratic expression models the height of the ball, in feet, where t is the time, in seconds.
y= -16t^2 + 25t+7
Given equation is in the form of
y= -16x^2 + V t + h
Where V represents the initial velocity and h represents the initial height of the ball
Now we compare our equation with the general equation
We have 7 in the place of h
So , 7 is the initial height of the ball
Answer is 7 is the initial height of ball when the player releases it

Consider the provided function [tex]f(x)=3(x+5)+\frac{4}{x}[/tex]
In order to find the value of [tex]f(a+2)[/tex]
Substitute x = a + 2 in the provided function.
[tex]f(a+2)=3((a+2)+5)+\frac{4}{a+2}[/tex]
[tex]f(a+2)=3(a+2+5)+\frac{4}{a+2}[/tex]
[tex]f(a+2)=3(a+7)+\frac{4}{a+2}[/tex]
Now, apply the distributive property: [tex]a(b+c)=ab+ac[/tex]
[tex]f(a+2)=3a+21+\frac{4}{a+2}[/tex]
Therefore, the value of [tex]f(a+2)[/tex] is [tex]3a+21+\frac{4}{a+2}[/tex].

Jim and Carla are scuba diving. Jim started out 12 feet below the surface. He descended 17 feet, rose 3 feet, and descended 8 more feet. Then he rested. Carla started out at the surface. She descended 19 feet, rose 3 feet, and descended another 17 feet. Then she rested. Which person rested at a greater depth? Complete the explanation.
Answer:
Jim reached a greater depth by one foot, as he started 12 feet below the surface.
Step-by-step explanation:
Jim
12 feet+17 feet = 29
29-3 feet (rose 3 feet) = 26
26+8= 34 feet
Carla
0 feet (surface)+ 19 feet= 19
19-3 feet= 16
16+17= 33 feet
After performing the depth calculations for both Jim and Carla's scuba diving, it was found that Carla is resting at a greater depth than Jim. Jim ended 24 feet below the surface, and Carla ended 33 feet below the surface.
Explanation:To start with, let's calculate how deep Jim and Carla each ended their dives. We begin with Jim, who started 12 feet below the surface, descended 17 feet, went up 3 feet and then descended another 8 feet. His total depth is therefore 12 - 17 + 3 - 8 = 24 feet below the surface.
Now let's calculate Carla's depth. Carla started at the surface (0 feet below), then descended 19 feet, ascended 3 feet, and descended another 17 feet. Her total depth is therefore 0 - 19 + 3 - 17 = 33 feet below the surface.
Comparing these two figures, Carla is resting at a greater depth than Jim.

If you subtract twelve from twice a number, the result is six.what is the number?
Final answer:
The number in question is 9. This is found by setting up the equation 2x - 12 = 6 and solving for x.
Explanation:
To find the number when twelve is subtracted from twice the number and the result is six, we set up the equation 2x - 12 = 6. To solve for the number (x), follow these steps:
Add 12 to both sides of the equation: 2x - 12 + 12 = 6 + 12, which simplifies to 2x = 18.Divide both sides by 2 to isolate x: 2x/2 = 18/2, which simplifies to x = 9.Therefore, the number that satisfies the condition is 9.
