3/8 + 1/8 - 2/7 + 1/4
Answer:
0.46428571428
Step-by-step explanation:
Answer:
13/28Step-by-step explanation:
3/8 + 1/8 = 4/8 = 1/2 = 0.5
1/2 - 2/7 = 3/14 = 0.214285714286
3/14 + 1/4 = 13/28 = 0.464285714286

You have given an equal sided triangle with side length a. A straight line connects the center
of the bottom side to the border of the triangle with an angle of α. Derive an expression for
the enclosed area A(α) with respect to the angle (see drawing
Answer:
Where α is an acute angle (first figure)
The area of the shaded triangle = ((√3)·a²/4)·sin(α)·csc(120 - α))
Where α is an obtuse angle (second figure)
The required area of the shaded region = (√3)·a²/4 + (√3)·a²/4)·sin(α)·sec(α + π/6)
Step-by-step explanation:
Where α is an acute angle (first figure)
The given parameters are;
The given triangle = Equilateral Triangle
Let the sides of the equilateral triangle = 2·a
Therefore;
The measure of each interior angles of the given triangle = 60°
Let c represent the side of the shaded triangle opposite ∠α and b represent the side of the shaded triangle opposite ∠60° and c, represent the third side of the shaded triangle, we have;
The sides of the equilateral triangle = 2·a
By sine rule, we have;
c/sin(α) = b/sin(60°) = a/sin(180 - (60 + α)) = a/sin(120 - α))
b = sin(60°) × a/sin(120 - α)) = (√3)/2 × a/sin(120 - α))
The area of the shaded triangle = 1/2 × a × b × sin(α) = 1/2 × a × (√3)/2 × a/sin(120 - α)) × sin(α) = ((√3)·a²/4)·sin(α)·csc(120 - α))
The area of the shaded triangle = ((√3)·a²/4)·sin(α)·csc(120 - α))
Where α is an obtuse angle (second figure)
The required area of the shaded region = The area of the equilateral triangle - The area of the small unshaded triangle, with base side a and interior angles, (180° - α), 60° and ((180 - (180° - α) - 60°) = ) α - 60°
The area of the unshaded triangle is found as follows;
By sine rule, we have;
c/sin(180° - α) = b/sin(60°) = a/sin(α - 60°)
b = sin(60°) × a/sin(α - 60°) = (√3)/2 × a/sin(α - 60°)
The area of the unshaded triangle = 1/2 × a × b × sin(α) = 1/2 × a × (√3)/2 × a/sin(α - 60°) × sin(α) = -((√3)·a²/4)·sin(α)·sec(α + π/6)
The area of the shaded triangle = -((√3)·a²/4)·sin(α)·sec(α + π/6)
The required area of the shaded region = 1/2×a²·sin(60°) - (-((√3)·a²/4)·sin(α)·sec(α + π/6))
The required area of the shaded region = (√3)·a²/4 + (√3)·a²/4)·sin(α)·sec(α + π/6)

Keiko, Juan, and Tony have a total of $80 in their wallets. Keiko has $5 less than Tony. Juan has 3 times what Tony has. How much does each have?
Answer:
Keiko 12 + Juan 51 + Tony 17 = $80
Step-by-step explanation:
K + J + T = 80
K=T-5
J=3T
T=T
T-5 + 3T + T = 80
5T -5 = 80 --> 5T = 85 --> T = 17
now that u know T=17, substitute the value of T to find K and J
K=(17)-5 = $12
J=3(17) = $51
T= $17

Given: a//b, m<3= 63 degrees
Find: m<6, m<7
(The < is used as the angle sign)
Answer:
i think 89
Step-by-step explanation:
Answer:
m∠6 = 117º
m∠7 = 63º
Step-by-step explanation:
m∠3 = m∠7 = 63º(corresponding angles)
180º - m∠3 = m∠6 = 117º (same side interior angles are supplementary)
or
180º-m∠7 = m∠6 = 117º (linear pair)

Answer:
The value of x in this equation is -23
Step-by-step explanation:
The given equation is:
[tex]-x-8 = 15[/tex]
The given equation is a linear equation in one variable. The solution of the equation requires isolating x on one side of the equation.
Properties of equality will be used to find the solution.
Using Addition property of equality
Adding 8 on both sides
[tex]-x-8+8 = 15+8\\-x = 23[/tex]
Multiplication property of equality
Multiplying both sides by -1
[tex]x = -23[/tex]
Verification:
[tex]-x-8 = 15\\-(-23)-8 = 15\\23-8 = 15\\15 = 15[/tex]
Hence,
The value of x in this equation is -23

Interpret the correlation coefficient.
the data show a ___ ___ correlation.
Answer:
ŷ = -0.18363X + 19.71681
-0.9685
Step-by-step explanation:
Given the data:
Mileage, x: 22 14 18 30 8 24
Price, y: 16 17 17 14 18 15
Using the online regression calculator :
The regression equation obtained is :
ŷ = -0.18363X + 19.71681
Where ;
y = predicted variable
- 0.18363 = slope or gradient
X = predictor variable
19.71681 = intercept
The correlation Coefficient R = -0.9685
This signifies a strong negative relationship between the x and y variable.
The line of best fit has an equation of:
y = -0.1875x + 19.625
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept.
Let x represent the mileages (in thousands of miles) and y the selling prices(in thousands of dollars) of used automobiles.
Plotting the points using geogebra graphing calculator, the line of best fit has an equation of:
y = -0.1875x + 19.625
Therefore the slope is -0.1875 and the y intercept is 19.625

Refer to the spinner. Find the odds of the spinner not landing on an even number.
• 1:3
•1:1
•2:1
•1:2
Explanation:
We have three numbers that aren't even, and they are {1,3,5}
There are three numbers that are even, and they are {2,4,6}
The odds in favor of not getting an even number is 3:3 = 1:1
To list the odds in favor, you write the number of ways to get what you want, followed by a colon, then the number of ways to get what you don't want. In this case, both counts are 3. The ratio 3:3 reduces to 1:1 after dividing both parts by 3.
Answer:
1:1
Step-by-step explanation:
how many odd sections are even: 3
how many sections are not even: 3
the odds are 3 : 3= 1:1
odds are what you expect to come out versus what you don't expect(favorable to un favorable).
confusion comes in when talking about probability
probability is what you want to come out versus the total chances whether odd or even(favorable to total outcomes). eg
in this example
the probability of it not landing on the even number is:
number of odd sections= 3 = 1:2
number of total outcomes= 6
Can someone help me with this, please???

Which Lines Are Parallel if M<4 = m<5? Justify Your Answer.
Answer:
Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4. That means angle 1 = angle 5 as well.
When a line intersects two parallel lines, the corresponding angles are equal. That is, if r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s. Angle 1 = Angle 5, Angle 2 = Angle 6, and so forth. Since we know angle 1 = angle 5, we can conclude that r and s are parallel.
