What is the surface area of a cylinder use 3.14 instead of pi button on your calculator the radius two the height is eight.
Please help and if any of you do ixl please let me know I need help with Lot of them !!
Answer:
125.60
Step-by-step explanation:
the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).
hope that makes sense!!
What is the area of the trapezoid?
Answer:
C) 100 m^2
Step-by-step explanation:
Area of a trapezoid= h*[(b1+b2)/2]
h=10
b1=8
b2=12
Therefore:
A=10*[(8+12)/2]
A=10*(20/2)
A=10*10
A=100
So the area of the trapezoid is 100 m^2

What is the definition of similarity? *
A. If two figures have the same angles, then they are similar.
B. If two figures have proportional side lengths, then they are similar.
C. If there is a sequence of transformations taking one figure to another, then they are similar.
D. If there is a sequence of rigid transformations and dilations, that take one figure to the other, then they are similar.
Answer:
The answer is A. If I get it right, please award me with brainliest.
Step-by-step explanation:
Similarity in Mathematics refers to two shapes resembling each other such that one can be acquired from the other using a sequence of dilations and rigid transformations. They have the same angle measures and proportional side lengths.
Explanation:In the field of Mathematics, particularly in Geometry, similarity refers to the concept that alludes to how well two shapes resemble each other. Two shapes are considered similar if you can obtain one from the other using a sequence of stretches, shrinks (know as dilations), and rigid transformations (like rotation, reflection, or translation).
In other words, option D is the most accurate: If there is a sequence of rigid transformations and dilations, that take one figure to the other, then they are similar. It's important to note that the characteristics of similar figures include having the same angle measures and proportional side lengths.

Namarachi earns a base pay of $2,200 per month. She also earns commission of 4% of her total sales. One month Namarachi earned $2,400. Explain how to find Namarachi’s total sales for that month. How much were her total sales?
Answer:
$5000
Step-by-step explanation:
To get the amount earned as commission, we deduct the fixed pay from the total earned pay. Given the total monthly earnings as $2400 while fixed pay of $2200, in this case, the amount of commission will be
Commission= 2400-2200=200
Since the commission is 4% of the total sales, then the total sales equivalent to 100% is given by cross multiplication
If4%=$200
100%=?
Total sales will be 100%*$200/4%=$5000

whats the least common denominator of 2/5 1/2 and 3/4?
Answer:
20
Step-by-step explanation:
Final answer:
The least common denominator for the fractions 2/5, 1/2, and 3/4 is 20, as it is the smallest number that all denominators can divide into without leaving a remainder.
Explanation:
The least common denominator (LCD) of the fractions 2/5, 1/2, and 3/4 is the smallest number that can be divided evenly by each of the denominators (5, 2, and 4, respectively). To find the LCD, we can list out the multiples of each denominator until we find a common multiple.
The multiples of 5 are 5, 10, 15, 20, 25, and so on. The multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. When we look at these lists, the smallest number that appears in all three lists is 20. Therefore, 20 is the least common denominator for the fractions 2/5, 1/2, and 3/4.
What percent of 20 is 8?
Answer: x = 40
Step-by-step explanation: I know that it's tempting to try to do percentage word problems in your head but this leads to a variety of careless mistakes. So I would advise always writing out the equation by simply reading the problem from left to right and solving it from there. That way you don't have to think about the problem at all until you get to your final answer.
So for this problem we have what percent. Since we know that percent means over 100 and what means x,
what percent would be x/100.
Of means times, 36 is 36, is means equals, and 81 is 81.
So we have the equation x/100 · 20 = 8.
We can rewrite this problem as 20x/100 = 8.
To get rid of the fraction, we multiply
both sides by 100 and we have 20x = 800.
Dividing both sides by 20, you can use a
calculator to find that that x = 40.
Now let's check to see if our answer makes sense.
We have 40% of 20 is 8.
Well we know that 100% of 20 would be 20. So 40% of 20 should be alot less than 20 so 8 seems to make sense.
I have attached my own work in the image provided.
Final answer:
To determine what percent of 20 is 8, you divide 8 by 20 and multiply by 100, which equals 40%. Thus, 8 is 40% of 20.
Explanation:
To find out what percent of 20 is 8, we use the formula for percentage which is
(Part/Whole) × 100. In this case, 8 is the part (the number we're trying to find the percentage for) and 20 is the whole (the reference number we're comparing to). So, we calculate (8/20) × 100 to get the percent.
Step-by-step calculation:
Divide 8 by 20 which equals 0.4.
Multiply 0.4 by 100 to convert it to a percent.
0.4 × 100 equals 40%.
Therefore, 8 is 40% of 20.

∘
98, degrees between Melissa and the big rock.
What is the distance across the river from Omkar to the big rock?
Do not round during your calculations. Round your final answer to the nearest meter.
Answer:
The distance across the river from Omkar to the big rock is 72 meters.
Step-by-step explanation:
Using the given information draw as triangle as shown below.
According to angle sum property, the sum of interior angles of a triangle is 180°.
In triangle ABC,
\angle A+\angle B+\angle C=180^{\circ}
98^{\circ}+33^{\circ}+\angle C=180^{\circ}
131^{\circ}+\angle C=180^{\circ}
\angle C=180^{\circ}-131^{\circ}=49^{\circ}
The measure of angle C is 49°.
Sine formula:
\frac{a}{\sin a}=\frac{b}{\sin b}=\frac{c}{\sin c}
Using sine formula in triangle ABC, we get
\frac{AC}{\sin B}=\frac{AB}{\sin C}
\frac{AC}{\sin 33^{\circ}}=\frac{100}{\sin 49^{\circ}}
AC=\frac{100}{\sin 49^{\circ}}\times \sin 33^{\circ}
AC=\frac{100}{0.7547}\cdot0.544639
AC=72.166
AC\approx 72
Therefore the distance across the river from Omkar to the big rock is 72 meters.

Miguel has a toolbox that measures 18.5 inches by 12.5 inches by 4 inches. What is the volume of the toolbox
It would be 925 inches cubed.
Step-by-step explanation:To find the volume, know that to find the volume of any rectangular prism (which is what this is) is to do Length * Width * Height to get the volume.
By doing, 18.5 * 12.5 * 4, you'll get your answer.
18.5 * 12.5 * 4 ---> 925
Remember to make in the unit of inches (because that's the unit it was asked in) and to write cubed at the end (since you are finding the area of a 3d object).
A table of values of a linear function is shown below.
Find the slope and y-intercept of the function's graph, and find the equation for the function.
Given:
A table of values of a linear function.
To find:
The slope, y-intercept and equation of the function.
Solution:
Take any two points on the table.
Let the points are (-1, -3) and (0, -6).
Slope of the line:
[tex]$m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]$m=\frac{-6-(-3)}{0-(-1)}[/tex]
[tex]$m=\frac{-6+3}{0+1}[/tex]
[tex]$m=\frac{-3}{1}[/tex]
m = -3
Slope of the function = -3
y-intercept of the function is the point where x = 0.
In the table y = -6 when x = 0
y-intercept = -6
Equation of a line:
y = mx + c
where m is the slope and c is the y-intercept
y = -3x + (-6)
y = -3x - 6
Equation of a function is y = -3x - 6.
The slope of the function's graph is 3, the y-intercept is 2, and the equation for the function is y = 3x + 2.
Explanation:To find the slope of the function's graph, we can use the formula: slope = (change in y) / (change in x). We can choose any two points from the table and calculate the slope. Let's choose the points (0,2) and (1,5). The change in y is 5 - 2 = 3, and the change in x is 1 - 0 = 1. Therefore, the slope is 3/1 = 3.
To find the y-intercept of the function's graph, we can use one of the points from the table. Let's use the point (0,2). Since the y-intercept is the value of y when x = 0, the y-intercept is 2.
The equation for a linear function is y = mx + b, where m is the slope and b is the y-intercept. So for this function, the equation is y = 3x + 2.
