Please help and give an explanation on how to find the value of x
Answer:
x = 30
2x =60
Step-by-step explanation:
the angle is a right angle- so that means it’s a 90 degree angle
so let’s set up an equation..
We get 90 degrees when we add 2x Plus x
So 2x + x = 90
then, 3x = 90
x= 30
you Can check your Answer by:
Do 2 times 30 = 60
and then 60+ 30
you will Get 90

from left, top, and bottom
Answer:
2/6
Step-by-step explanation:
Convert 1/2 to something similar to 1/6
1 times 3 is 3
2 times 3 is 6
so now do 3/6 -1/6
Dont change the denominator at all, just subtract the numerator. By doing that you get 2/6
find the value of x, y, and z
Answer:
B
Step-by-step explanation:
The diagonals of a rhombus are at right angles to each other, then
∠ 1 = ∠ 2 = ∠ 3 = 90° so
10x = 90 ( divide both sides by 10 )
x = 9
x + y = 90
9 + y = 90 ( subtract 9 from both sides )
y = 81
9z = 90 ( divide both sides by 9 )
z = 10
Mr chow is buying rolls of paper for the school. This is a lost of the suppliers, the size of their rolls, and their cost per roll. supplier x sells 25 meter rolls for 18.98, supplier y sells 30 meter rolls for 21.89, supplier z sells 40 meter rolls for 29.59 to the nearest cent what is the cost per meter for a roll of paper from the least expensive supplier
Answer:
0.73
Step-by-step explanation:
cost per meter for a roll of paper = total cost / total meter of rolls sold
Supplier x = 18.98 / 25 = 0.76
Supplier y = 21.89 / 30 = 0.73
supplier z = 29.59 / 40 = 0.74
the lowest per unit cost is 0.73

a box contains 44table tennis balls having same shape and size.Among them 33 are black and remaining balls are red .two balls are drawn randomly one after another without replacement show the probability of all posible outcomes in a tree diagram.
Answer:
The probability that both balls are red is 5.81%, that one is red and one black is 38.36%, and that both are black 55.81%.
Step-by-step explanation:
Given that a box contains 44 table tennis balls having the same shape and size, and among them 33 are black and remaining balls are red, if two balls are drawn randomly one after another without replacement, to show the probability of all possible outcomes the following calculations must be done:
Red + red:
11/44 + 10/43 = 0.25 x 0.2325 = 0.0581
Red + black:
11/44 + 33/43 = 0.25 x 0.7674 = 0.1918
Black + red:
33/44 + 11/43 = 0.75 x 0.2558 = 0.1918
Black + black:
33/44 + 32/43 = 0.75 x 0.7441 = 0.5581
19.18 x 2 = 38.36
Therefore, the probability that both balls are red is 5.81%, that one is red and one black is 38.36%, and that both are black 55.81%.

Circle A has center of (4, 6) and a radius of 5, and circle B has a center of (1, 0) and a radius of 15. What steps will help show that circle A is similar to circle B? (5 points) Group of answer choices Reflect circle A over the y-axis. Dilate circle A by a scale factor of 3. Translate circle A using the rule (x − 3, y + 6). Rotate circle A 180° about the center.
Answer:
Divide and then multiply the smaller ratio to get an equal ratio to the first one
Step-by-step explanation:
It helps a lot with algebra
Answer:
Dilate circle A by a scale factor of 3.
Step-by-step explanation:
In order to show if two triangles are similar you have to translate and dialate one of the triangles to compare it to the other one. So A and D are not it. The formula for C is incorrect so therefore the answer is B. Also i took the test :D

Answer:
A. 72π m^3
Step-by-step explanation:
The radius of the cone would be half the diameter, or 6m.
The formula for the volume of a cone is:
V= (πr^2h) / 3
We can substitute what we have:
V = (π * (6)^2 * 6 )/ 3
V = (216 π) / 3
V = 72π m^3

Use the property to convert each expression from exponent form to radical form.
[tex](a)^{\frac{1}{n}}=\sqrt[n]{a}[/tex]
a). [tex](b)^{\frac{4}{5}}=(b^4)^\frac{4}{5}[/tex]
[tex]=\sqrt[5]{b^4}[/tex]
b). [tex](8x)^\frac{2}{3}=[(8x)^2]^\frac{1}{3}[/tex]
[tex]=[64x^2]^\frac{1}{3}[/tex]
[tex]=[(4)^3x^2]^\frac{1}{3}[/tex]
[tex]=(4^3)^\frac{1}{3}(x^2)^\frac{1}{3}[/tex]

If a student studies for 6 hours, they will receive a grade of about 100.
In general, the longer time spent studying, the higher the student's grade.
Answer:
- If a student studies for 6 hours, they will receive a grade of about 100.
- In general, the longer time spent studying, the higher the student's grade.
Step-by-step explanation:
Given
See attachment for plot
Required
Select all correct options
First, we determine the equation of best fit.
Pick two corresponding points on the plot
[tex](x_1,y_1) = (2,70)[/tex]
[tex](x_2,y_2) = (4,85)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
[tex]m = \frac{85 - 70}{4-2}[/tex]
[tex]m = \frac{15}{2}[/tex]
[tex]m = 7.5[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 7.5(x - 2) + 70[/tex]
[tex]y = 7.5x - 15 + 70[/tex]
[tex]y = 7.5x +55[/tex]
The above represents the line of best fit.
By comparison, (a) is incorrect
We calculate the slope to be:
[tex]m = 7.5[/tex]
Since the slope is positive, then the relationship is positive (b is incorrect)
Also, the positive slope implies that, as x increases, y also increase.
Hence, (d) is correct.
For (c), we substitute 6 for x in the calculated equation of best fit
[tex]y = 7.5x +55[/tex]
[tex]y = 7.5 * 6 + 55[/tex]
[tex]y = 45 + 55[/tex]
[tex]y = 100[/tex]
This shows that (c) is true because 6 hours of study gives a grade of 100
