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 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.

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.

∘
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.

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

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).

The probability that the backpack is pink or canvas is option (c) 0.9.
The probability that the backpack is pink or canvas can be calculated using the formula for the probability of the union of two events:
P(A or B) = P(A) + P(B) - P(A and B).
According to the question,
A represents: the event that the backpack is pink
B represents: the event that the backpack is the canvas
Substituting the given probabilities, we get:
P(pink or canvas) = 0.7 + 0.7 - 0.5 = 0.9.
So, the probability that the backpack is pink or canvas is option (c) 0.9.

A rectangular stained glass window is made up of identical triangular parts as pictured below.
36 inches
48 inches
What is the area of the shaded triangular section?
18 square inches
36 square inches
72 square inches
144 square inches
Answer:
The area of the shaded triangular section is 72 square inches
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The rectangular stained glass can be divided into 24 identical triangular parts
step 1
Determine the area of complete rectangle
[tex]A=(48)(36)=1,728\ in^2[/tex]
step 2
Divide the area of complete rectangle by 24
[tex]1,728/24=72\ in^2[/tex]
therefore
The area of the shaded triangular section is 72 square inches
Answer:
72 square inches
Step-by-step explanation:
The image is shown below.
The area of a rectangle is length times width.
Length is 48 and width is 36
Hence, area of whole rectangle is:
Area = 48 * 36 = 1728
Now, the whole figure is broken down into
24 congruent triangles
So, each triangle's area is:
1728/24 = 72 square inches
The shaded region is ONE of the triangles, so the shaded region area is:
72 square inches

Since the line of length 16 is a tangent to the circle, then the angle between it and the radius is right.
? is the hypotenuse of the right triangle formed.
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
