20% of what number is 30
Answer:
150
Step-by-step explanation:
20 percent of 150 is 30.
To check the answer... 150 times 0.2 is 30.
Answer:
150
20 percent of what number equals 30; Answer: 150.
Step-by-step explanation:
20% of what is 30?
Written using the formula: X = 30 ÷ 20%
Convert the percent to a decimal.
20% ÷ 100 = 0.2.
X = 30 ÷ 0.2.
X = 150.
So 20% of 150 is 30.

Triangle Inequalities part 2 help please
Answer:
The perimeter can not be 26 inches
Step-by-step explanation:
Given
[tex]Side\ 1 =19[/tex]
[tex]Side\ 2 =16[/tex]
Required
Is a perimeter of 26 possible?
First, calculate the possible side 3
[tex]Side\ 3 = Perimeter - Side\ 1 - Side\ 2[/tex]
[tex]Side\ 3 = 26 - 16 - 19[/tex]
[tex]Side\ 3 = -9[/tex]
The side length can not be negative.
So, the perimeter can not 26 inches
Reflection across y=3
The reflected coordinates of the triangle along y = 3 are X'(0, - 1), U'(3, - 1) and L'(3, - 5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, a triangle is reflected along y = 3.
First, the coordinates (x, y) of the triangle are X(0, 5), U(-3, 5) and L(-3, 1).
We know reflected along the y-axis is (-x, y) so reflection along y = 3 is
(-x, y - 2×3).
∴ X'(0, - 1), U'(3, - 1) and L'(3, - 5).

First,let find the area of AMY. It is given that
Am=5
MY=7
AY=3
We can add up those numbers to find the perimeter.
5+7+3=15.
2. Since AMY and MEG are similar shapes, there side lengths are proportional, and their perimeter is also proportional.
The only transformation that can accomplish that is a dilation.
MEG is a dilation of AMY by 1/3. so that means MEG is 3 times smaller than AMY.
We would just divide 3 by the perimeter of AMY to find MEG.

TRIGONOMETRY
Answer:
9). x = 36.9°
10). x = 18.3°
Step-by-step explanation:
9). By applying tangent rule in the given triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{12}[/tex]
x = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]
x = 36.87°
x = 36.9°
10). By applying sine rule in the given triangle,
sin(x) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(x) = [tex]\frac{11}{35}[/tex]
x = [tex]\text{sin}^{-1}(\frac{11}{35})[/tex]
x = 18.32
x ≈ 18.3°

Ok so I have this problem, 12x+24=6x+3. WHAT DO I DO IF THE X HAS DIFFERENT NUMBERS. Oh and for 5-2x=2x-5 what do i do if ones a negative and ones a positive. Im trying to find the answer and if its 1 solution, no solution, or infinite solutions. Im sure people on here can reply quicker then my math teacher.
Answer: one solution; that solution is x = -7/2 which is the same as x = -3.5
====================================================
Work Shown:
The idea is to get all the x terms to one side, and the other stuff to the other side. We follow PEMDAS in reverse to help isolate x
12x+24 = 6x+3
12x+24-24 = 6x+3-24 .... subtract 24 from both sides
12x = 6x-21
12x-6x = 6x-21-6x ...... subtract 6x from both sides
6x = -21 ...... now the x terms are all on one side
6x/6 = -21/6 ...... dividing both sides by 6
x = -21/6
x = (-7*3)/(2*3)
x = -7/2
x = -3.5
This is the only solution. Whenever we have different coefficients for the x terms like this, we can see right off the bat we have exactly one solution. Consider graphing y = 12x+24 and y = 6x+3. The two lines will intersect at the point (x,y) where the x coordinate is the solution to the original equation. There is only one point of intersection which corresponds to exactly one solution.
The thing to notice about y = 12x+24 and y = 6x+3 is that the slopes are not the same, so the lines aren't parallel. Parallel lines always have equal slopes but different y intercepts. If your teacher gave you 12x+24 = 12x+3, then the two lines to graph would be y = 12x+24 and y = 12x+3. At this point, we would get two parallel lines that don't intersect, and therefore we wouldn't get any solutions here.

a grocery store receives a shipment of 700 oranges the manager randomly selects 25 oranges to weigh. in that sample 2 oranges weigh 5 ounces. How many oranges in the shipment can the manager predict weigh 5 ounces
The number of oranges in the shipment can the manager predict weighing 5 ounces would be; 56.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inversely proportional, can be built to find the desired measures in the problem.
Given that a grocery store receives a shipment of 700 oranges the manager randomly selects 25 oranges to weigh in that sample 2 oranges weigh 5 ounces.
Now set up a proportion;
2/25 = (x)700
Cross multiplication;
700(2)= 25(x)
1400/25=x
x=56
Therefore, the number of oranges in the shipment can the manager predicts weighing 5 ounces would be; 56.

Median is the middle value.
Each set has 7 numbers so put the numbers in order from smallest to largest. The median would be the 4th number in the sets.
Only 2 sets have the number 15 in them so those are the only two you need to look at.
The 3rd choice is the correct answer.
