Identify the relationship (complementary, linear pair/supplementary, or vertical) and find the measure of angle b in the image below
Answer:
Relationship: supplementary
B = 110
Step-by-step explanation:
The two angles shown form straight line
Angles that form a straight line add up to equal 180. Angles that add up to 180 are known as supplementary angles
If the angles add up to equal 180 then b + 70 = 180
Subtract 70 from both sides
b = 110
points E, F and D are located on the circle C. The measure of arc ED is 108.

Answer:
One solution;
[tex]x=-1\frac{2}{7}[/tex]
[tex]y=-5\frac{3}{7}[/tex]
Step-by-step explanation:
The method of elimination is a way of solving a system of equations. There are many steps involved in this process. First, one must manipulate one of the equations in the system by multiplying each term in it by a certain number such that one of the variables is the inverse of the other like the variable in the other equation. Then one must add the two equations. This will eliminate one of the variables in the equations. After doing so, one has to use inverse operations to solve for the other variable. Finally, one will back solve, substitute the value of the solved variable into one of the equations and solve for the remaining unknown variable.
[tex]\left \{ {{y=5x+1} \atop {y=-2x-8}} \right.[/tex]
Manipulate the system;
[tex]\left \{ {{y=5x+1*(-1)} \atop {y=-2x-8}} \right.[/tex]
Simplify,
[tex]\left \{ {{-y=-5x-1} \atop {y=-2x-8}} \right.[/tex]
Add the equations,
[tex]\left \{ {{-y=-5x-1} \atop {y=-2x-8}} \right.[/tex]
[tex]0=-7x-9[/tex]
Inverse operations,
[tex]0=-7x-9[/tex]
[tex]7x=-9[/tex]
[tex]x=-\frac{9}{7}[/tex]
[tex]x=-1\frac{2}{7}[/tex]
Backsolve,
[tex]y=-2x-8[/tex]
Substitute
[tex]y=-2(-\frac{9}{7})-8[/tex]
Simplify,
[tex]y=-2(-\frac{9}{7})-8[/tex]
[tex]y=\frac{18}{7}-8[/tex]
[tex]y=\frac{18}{7}-8\\y=-\frac{38}{7}[/tex]
[tex]y=-5\frac{3}{7}[/tex]
Anthony is building a rectangular shaped swimming pool with a perimeter of 80 feet. Determine a function A(w) that models the area of the top surface of the swimming pool in terms of width W. A(w)= For w>0
Answer:
[tex]A(w) = 40w - w^2[/tex]
Step-by-step explanation:
Given
[tex]P = 80[/tex] --- perimeter
Required
Define the area in terms of width
The perimeter of the pool is:
[tex]P =2(l + w)[/tex]
Where:
[tex]l\to length[/tex]
[tex]w\to width[/tex]
So:
[tex]80 =2(l + w)[/tex]
Divide by 2
[tex]40 =l + w[/tex]
Make l the subject
[tex]l = 40-w[/tex]
The area is then calculated as;
[tex]A(w) = l * w[/tex]
Substitute: [tex]l = 40-w[/tex]
[tex]A(w) = (40 - w) * w[/tex]
[tex]A(w) = 40w - w^2[/tex]

please help and hurry!!
Please click the photo and there are two questions to solve .Please help me guys
Answer:
Step-by-step explanation:
Distance formula:
[tex]\sqrt{(X_2-X_1)^2+(Y_2-Y_1)^2}[/tex]
Distance for AB
[tex]\sqrt{(4-2)^2+(1-(-5))^2}=\sqrt{4+36}=\sqrt{40}\\[/tex]
Distance for AC
[tex]\sqrt{(8-2)^2+(-3-(-5))^2}=\sqrt{36+4}=\sqrt{40}[/tex]
2.
same formula solve when positive
[tex]5=\sqrt{(6-3)^2+(y-2)^2}\\25=9+(y-2)^2\\16=(y-2)^2\\4=y-2\\6=y[/tex]
Now when it's negative
[tex]5=\sqrt{(6-3)^2+(y-2)^2}\\25=9+(y-2)^2\\16=(y-2)^2\\-4=y-2\\y=-2[/tex]
so y can equal 6 or -2

Answer:
[tex]y = - \frac{1}{2} x + 4[/tex]
Step-by-step explanation:
Let us consider two points through which the line passes through
[tex](x_1 , y _ 1 ) = ( 0 , 4 ) \ and \ (x_ 2 , y _ 2 ) = ( 4, 2 )[/tex]
Step 1 : Find slope of the line
[tex]Slope, m_1 = \frac{rise}{run} \\\\That \ is \ m_1 \ = \frac{y_2 - y _ 1}{x_2 - x_1}[/tex]
[tex]= \frac{2 - 4}{4-0} \\\\=-\frac{2}{4}\\\\= - \frac{1}{2}[/tex]
Step 2 : Find equation of the line.
[tex](y - y _ 1) = m_ 1 (x - x_1)\\\\( y - 4) = - \frac{1}{2}(x - 0)\\\\y = -\frac{1}{2}x + 4[/tex]

A) 5/13
B) 5/12
C) 13/5
D) 12/13
Answer:
A. 5/13
Step-by-step explanation:
Cos = Adjacent/Hypotenuse
Adjacent of B = 5
Hypotenuse = 13
Hence CosB = 5/13

Step-by-step explanation:
9: A rectangular room is 14m long and 8m wide. Jessica is going to carpet the room with carpet that costs £17.50 per square metre. Work out the cost of carpeting the room.
Answer:
£1,960
Step-by-step explanation:
Find the area of the room using the formula, A = lw
Plug in the length and width, and solve:
A = lw
A = 14(8)
A = 112
So, the area of the room is 112 square meters. Find the cost of carpeting the room by multiplying this by the price, £17.50
112(17.5)
= 1960
So, the price will be £1,960

Answer:
DBH
Step-by-step explanation:
#1
Initial Price = 100% = 18
Discount = 15% = x
0.15 ( 18 ) = 0.15 * 18 = 2.7
Discount = $2.7 or $2.70
Letter = D
#2
Initial Price = 100% = 450
Markup = 20% = x
0.20 ( 450 ) = 1/5 of 450 = 90
Markup = $90
Letter = B
#3
Initial Payment = 100% = 37.60
Tip = 15% = x
0.15 ( 37.60 ) = 0.15 * 37.60 = 5.64
Tip = $5.64
Letter = H
Your Code = DBH

Craig threw a handful of identically shaped buttons into the air then collected 14 bottoms that landed on the carpet. Is this sample of the buttons likely to be biased yes or no
Answer:
possible?? but I think that there is a typo, and that there would not be a bias
Step-by-step explanation:
can we assume that there are no typos in the question
he threw BUTTONS in the air, and look at buttons that landed with the BOTTOMS facing up ??? in that case the weight might bias the orientation of the landing... I think that you have a typo and it just says that he collected 14 BUTTONS, in that case given that they are "IDENTICAL" we most likely can assume that there would be no bias (size color, texture are all the same)

Check whether (0, -2) is solution of the equation x - 2y = 4 or not
Answer:
Step-by-step explanation:
Plugin x = 0 & y = -2 in the LHS of the equation. After substituting, if you get the RHS, then this point is the solution of the equation.
x - 2y = 0 - 2*(-2)
= 0 + 4
= 4 = RHS.
(0,-2) is solution of the equation.

Mrs.Tate is 5 feet 3 inches tall. Her daughter is 4 feet 8 inches tall. How much taller is Mrs.Tate than her daughter?
A) 5 inches
B) 7 inches
C) 1 foot 5 inches
D) 1 foot 7 inches
========================================================
Explanation:
1 foot = 12 inches
5 feet = 60 inches (multiply both sides by 5)
5 ft, 3 in = 63 inches (add 3 inches to both sides)
Through similar steps, you should find that 4 ft 8 in converts to 56 inches
The difference is 63-56 = 7 inches
Solve for x:
4x + 1 = 7x - 5
Answer:
x = 2
Step-by-step explanation:
First, subtract 4x from both sides:
4x + 1 = 7x - 5
1 = 3x - 5
Add 5 to both sides:
6 = 3x
Divide each side by 2:
2 = x
So, the answer is x = 2
Answer:
2 =x
Step-by-step explanation:
4x + 1 = 7x - 5
Subtract 4x from each side
4x-4x + 1 = 7x-4x - 5
1 = 3x-5
Add 5 to each side
1+5 = 3x-5+5
6 = 3x
Divide each side by 3
6/3 = 3x/3
2 =x

A train is traveling at a constant
speed, and its distance over time is
shownin the graph. What is the speed
of the train?
Answer:
It looks like 35 miles per hour
Step-by-step explanation:
if you look at the vertical line between 0 and 2 (which is the one hour mark) on the horizontal axis of the graph you can see the line of the graph crossed under the 40 mi. Therefore the train traveled about 35 miles in one hour (or 35 mph) because there are no other answers under 40.
In a wildlife park, there were 18 gray wolves. After three years, there were 27 gray wolves. What is the percent gain?
Answer:
50%.
Step-by-step explanation:
Gain as a fraction is (27-18) /18
= 9/18
= 1/2.
Percent gain = 1/2 * 100 = 50%.

Answer:
[tex]5^\frac{5}{6}[/tex]
Step-by-step explanation:
[tex]\sqrt{5}[/tex] can be represented as [tex]5^{\frac{1}{2}}[/tex] and [tex]\sqrt[3]5}[/tex] can be represented as [tex]5^{\frac{1}{3}}[/tex]. Therefore, the expression can be rewritten as:
[tex]5^{\frac{1}{2}}*5^{\frac{1}{3}}[/tex]
The rule for multiplying two exponents with the same base is you add the exponents. For example: [tex]x^m*x^k=x^{m+k}[/tex]
We can use the same property to get:
[tex]5^{\frac{1}{2} +\frac{1}{3}}[/tex]
which is just [tex]5^\frac{5}{6}[/tex] after you add the fractions
