Solve the equation. Then check your solution. – two-fifths + a = One-fifth a. Three-fifths c. StartFraction 3 Over 10 EndFraction b. Negative one-fifth d. Negative three-fifths
Answers
Answer:
a = Negative one-fifth
Step-by-step explanation:
The given equation is :
[tex]\dfrac{2}{5}+a=\dfrac{1}{5}[/tex]
We need to find the value of a.
Subtract 2/5 from both sides.
[tex]\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}[/tex]
So, the correct answer is Negative one-fifth. Hence, the correct option is (b).

O Center: (7, 2); Radius = 100
O Center: (7, 2); Radius - V10
O Center:(-7, - 2); Radius = 100
O Center:(-7, -2); Radius = 10
Answers
Answer:
Center = (7, 2); Radius = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
(x - 7)^2 + (y - 2)^2 = 10
center = (7, 2)
Radius = [tex]\sqrt{10}[/tex]
Answer:
(x - 7)^2 + (y - 2)^2 = 10
center = (7, 2)
Radius = √10

Question mark 1: Match the triangle to correct function and answer
Answers
Answer:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]x \approx 15.900[/tex]
Step-by-step explanation:
Each triangle is solved by means of trigonometric relations:
Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16
[tex]\cos 58^{\circ} = \frac{x}{16}[/tex]
[tex]x = 16\cdot \cos 58^{\circ}[/tex]
[tex]x \approx 8.479[/tex]
Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18
[tex]\tan 44^{\circ} = \frac{x}{18}[/tex]
[tex]x = 18\cdot \tan 44^{\circ}[/tex]
[tex]x \approx 17.382[/tex]
Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12
[tex]\sin 49^{\circ} = \frac{12}{x}[/tex]
[tex]x = \frac{12}{\sin 49^{\circ}}[/tex]
[tex]x \approx 15.900[/tex]

Mark said, “in the data set,4 5, 5, 8, the mean and mode the same.” Is he correct? Explain why or why not
Answers
Answer:
Mark is wrong.
Step-by-step explanation:
The mean of the data set is 5.5 because 4 + 5 + 5 + 8= 22. 22 divided by 4= 5.5. The mode is the number which shows up the most. 5 shows up the most in the data set, however 5 is not equal to 5.5. Therefore, Mark is incorrect.

Find the center, vertices, and foci of the ellipse with equation x squared divided by 9 plus y squared divided by 25
Answers
Answer:
[tex]C=(0,0)[/tex]
[tex]F=(\pm 4,0)[/tex]
[tex]V=(\pm 5,0)[/tex]
Step-by-step explanation:
From the question we are told that:
The Equation
[tex]\frac{x^2}{9}*\frac{y^2}{25}[/tex]
Generally
From the Equation
[tex]a^2=25[/tex]
[tex]a=5\\b^2=9\\b=3[/tex]
Therefore
[tex]c=\sqrt{a^2-b^2}[/tex]
[tex]c=\sqrt{25-9}[/tex]

Step-by-step explanation:
The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.
6 + 2 + 8
6 * 2 = 12
6 * 8 = 48
Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2
12 + 48 = 60
60 - 2 = 58
Put them together

Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents
Answers
Given:
In a circle, two chords AK and LJ intersect each other inside the circle at M.
Measure of arc AJ = 65 degrees.
Measure of arc KL = 85 degrees.
To find:
The measure of angle KML.
Solution:
Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.
Using Intersecting chords theorem, we get
[tex]m\angle KML =\dfrac{1}{2}(arcKL+arcAJ)[/tex]
[tex]m\angle KML =\dfrac{1}{2}(85^\circ +65^\circ )[/tex]
[tex]m\angle KML =\dfrac{1}{2}(150^\circ )[/tex]
[tex]m\angle KML =75^\circ[/tex]
Therefore, the measure of angle KML is 75 degrees.

Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
Answer:
18.) x = 6
20.) x = 11
Step-by-step explanation:
18.)
We know that line segments FC and ED are parallel to each other so they are congruent to each other:
-1 + 2x = 5 + x
-1 + x = 5
x = 6
20.)
We know that line segments DE and CF are parallel to each other so they are congruent to each other:
18 = -4 + 2x
22 = 2x
22/2 = x
11 = x

A cluster sample is when a population is divided into groups known as clusters. Samples are then randomly selected from this sample. It is a method of probability sampling used for large populations.
The airline first divided the population of travellers by months travelled. this is the cluster. From within the cluster, 10 samples are then chosen
