Find the total cost of a $20 lunch with an 18% tip.

Mathematics
1 answer:
Pachacha [2.7K]2 years ago
8 0

Answer:

$23.6

Step-by-step explanation:

The lunch normally costs $20

But you give a 18% TIP on top of that

Certainly, it will cost more. Lets find out how much exactly.

First, we need to find 18% of 20 and then ADD it to 20 to find FINAL LUNCH COST.

To convert percentage to decimal, we divide by hundred. After that we multiply with 20 to get 18% of 20. Process shown belowL

18% = 18/100 = 0.18

Then,

0.18 * 20 = $3.6

Adding to $20, we get total cost:

20 + 3.6 = 23.6 dollars

Total Cost = $23.6

When was the last time that texas tried to become its own state
Rudik [331]

Answer:

The Texas Declaration of Independence was signed in 1836 and the Texas Republic ratified its own constitution shortly after. In 1837, the U.S. formally recognized Texas as a nation, but the new country struggled economically without any of the resources of its larger neighbors, leading most (but not all) residents to welcome statehood by the time it came through in 1845. Only a little more than a decade passed, however, before the state tried to secede from its national government again, joining with the Confederacy in 1861.

What is the volume of this prism? <br> A. 23.9 ^3<br> B. 47.7 cm^3<br> C. 4.50 cm^3<br> D. 9.00 cm^3
melisa1 [442]

Answer: A) 23.9

Step-by-step explanation:

volume of a shape means the area of its base multiplied by its height

so , the base here is a right angle triangle it's area equals 1/2*b*h = 1/2*3*6=9 m² and the prism height is 2.65.

therefore the volume is 2.65*9

URGENT need answer quick
beks73 [17]

Answer:

Part A: x = 4.

Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.

MNOP is similar to QRST with a scale factor of 5 : 4. MP = 85mm. What is the value of QT?
chubhunter [2.5K]
MNOP is similar to QRST with ratio of 5:4<span>. That means the MP:QT ratio would also be 5:4

The length of QT would be
</span>MP/QT = 5/4<span>
85mm/QT=5/4
85mm*4= 5*QT
5QT= 340
QT=68mm</span>

independent variable. what is the independent variable? what are you deliberately choosing or changing?
liq [111]

The independent variable is the factor that you purposely change or control in order to see what effect it has. The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable. The independent variable is graphed on the x-axis.

To identify dependent studies variables, search for objects in your studies query or speculation that sees the result, effect, or outcome of changing the independent variable. The basic rule is to search for what reasons for reactions and what receives the results.

The statistical courting between variables is referred to as their correlation. A correlation might be high-quality, which means each variable circulates in the same direction, or bad, meaning that once one variable's price will increase, the opposite variables' values decrease.

Making sure that certain research variables are managed will increase the reliability and validity of the test, by ensuring that other causal consequences are removed. This safeguard makes it simpler for other researchers to repeat the experiment and comprehensively test the results.
