Find the missing angles and sides
Step-by-step explanation:
m∠1 = 180-100 = 80
m∠2 = 180-150 = 30
m∠3 = 180-(80+30) = 180 - 110 = 70
using the law of sine :
AC/sin(m∠2) = 5/sin(m∠3) ⇒ AC = sin(m∠2)*(5/sin(m∠3)) = sin(30)×(5÷sin(70))
=2.66044443119
CB/sin(m∠1) = 5/sin(m∠3) ⇒ CB = sin(m∠1)*(5/sin(m∠3)) ⇒ CB = sin(80)×(5÷sin(70)) = 5.240052604588

2x + 3y = 6

3 0
A line is described using the equation 2x + 3y = 6. The table lists the coordinates of two points on the line, the y-intercept and the x-intercept. Find the slope of this line.
A) The slope is 2.
B) The slope is 3.
C) The slope is −3/2
D) The slope is −2/3
Answer:
D)The slope is -2/3
Step-by-step explanation:
First, put this equation in slope-intercept form by subtracting 2x on both sides:
2x+3y=6
-2x. -2x
Your equation should be:3y=-2x+6
Then, divide the whole equation by 3 since y has to be by itself
3y=-2x+6
---- ------
3. 3
Your equation should be y=-2/3x+6
Since the slope in slope-intercept form is m in y=mx+b, -2/3×=m
Final answer:D) The slope is -2/3

What is the scale factor for this dilation? Please show your work
Answer:
Dilation factor is 2/3
Step-by-step explanation:
Look at both flat lines (M to S and M' to S') and find their lengths.
M to S = 9 units
M' to S' = 6 units
The triangle has gotten smaller so the dilation factor is a fraction
new/original = 6/9 = .66666666 or 2/3
Dilation factor is 2/3
What is the value of y
Answer: y=54
Step-by-step explanation: since a triangles angles =180 and you just have this equation 180-72=2y that equals 108=2y
Answer:
The answer is B. 54 degrees.
Step-by-step explanation:
A triangle must be 180 degrees when all three angles are added together. 180 minus 72 is 108 degrees, which you have to divide by two, because there are two y values.
You can check this by adding 72 plus 54 plus 54 to get 180 degrees total.

Given that ACDE, CBFG, and ABIH are squares and the side of the equilateral △ABC is 1 in. Find the square of the value of the shaded area.
Answer:
6.75
Step-by-step explanation:
The shaded area amounts to two congruent equilateral triangles. Each has a side length of 2(1 in)cos(30°) = √3 in.
The height of an equilateral triangle with side length √3 is ...
height = (√3 in)sin(60°) = 3/2 in
Then the area of the two equilateral triangles is ...
A = bh = (√3 in)(3/2 in) = 3√3/2 in^2
The square of the numerical value of the area is ...
A^2 = ((3/2)(√3))^2 = 27/4 = 6.75
The square of the shaded area is 6.75.
A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per month find the finance charge.
$10,900
$3,600
$1, 500
$8,400
Answer:
Option (3). $1500
Step-by-step explanation:
Cost price of the jukebox = $9400
Down payment made by the diner = $1000
Diner agreed to pay the rest amount by $275 per month for 36 months
Total amount to be paid by the diner = Down payment + monthly payments
= 1000 + 275×36
= 1000 + 9900
= $10900
Finance charge = 10900 - 9400
= $1500
Therefore, option (3). 1500 will be the answer.

The volume of a sphere with a radius of 5 cm is approximately _[blank]_ cm3.
Enter the value that correctly fills in the blank in the previous sentence.
Use 3.14 for π, and round your answer to the nearest hundredths place if necessary.
Answer: The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere (V) = 4/3 π radius³
Replacing with the values given and solving for V (volume)
V = 4/3 (3.14) 5³ = 4/3 (3.14) 125= 523.33 cubic centimeters
The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.

−6x+14<−28 OR 9x+15≤−12
Answer:x>7 or x ≤ -3
Solving the 1st inequality
-6x +14 < -28 --------------- (Collect like terms)
-6x < -28 - 14
-6x < - 42 -------------------- (Divide both sides by -6)
Note: If you decide an inequality expression by a negative value, the inequality sign changes)
-6x/-6 > -42/-6
x > 7
Solving the 2nd inequality
9x + 15 ≤ −12 ----------- (Collect like terms)
9x ≤ −12 - 15
9x ≤ −27 ------------------(Divide both sides by 9)
9
9x/9 ≤ −27/9
x ≤ -3
Bring both results together, we get
x>7 or x ≤ -3
The final result is complex (i.e. can't be combined together).
Step-by-step explanation:
Answer:
x> 7 OR x ≤−3
Step-by-step explanation:
−6x+14<−28 OR 9x+15≤−12
Solve them separately and then put back together
−6x+14<−28
Subtract 14 from each side
-6x +14-14 <-28-14
-6x <-42
Divide each side by -6, remembering to flip the inequality
-6x/-6 > -42/-6
x> 7
9x+15≤−12
Subtract 15 from each side
9x +15-15 ≤−12 -15
9x ≤−27
Divide each side by 9
9x/9 ≤−27/9
x ≤−3
Bella wants to know how tall the oak tree in her back yard is, so she picks
a point that is 75 feet away from the base of the tree. She measures the
angle of elevation to be 40° from this point to the top of the tree. To the
nearest tenth of a foot, how tall is
A-89.4 feet
B-62.9 ft
C-48.2 ft
D-57.5 ft
Answer:
B = 62.9ft
Step-by-step explanation:
The distance where she is from the oak tree is 75ft,
The angle of elevation the stone makes with the top of the oak tree is 40°
The height of the tree is x ft
See attached document for better illustration
Using SOHCAHTOA,
Tanθ = opposite/ adjacent
θ = 40°
Opposite = x ft
Adjacent = 75ft
Tan40 = x / 75
X = 75 × tan40
X = 75 × 0.8390
X = 62.92ft
The height of the oak tree is 62.9ft

You are given these direccions begin at the origin move right 4 units then down 3 units what ordered pair have you just graphed
Answer:
(4, -3)
Step-by-step explanation:
The origin is at (0,0). When you move right or left, you change the x-coordinate, or the first coordinate. You moved right which is in the positive direction so now your coordinate is (4,0).
When you move up or down, you change the y-coordinate, or the second coordinate. You moved down which is in the negative direction so your final coordinate is (4, -3).

in 1900, greenville had a population of 4000 people. Greenville's population increased by 100 people each year. Springfield had a population of 1000 people. Springfields population increased bu 4% each year. In what year were the populations about equal?
Answer: year 1948
Step-by-step explanation:
1900 is our t = 0
The population of Greenville can be written as:
G = 4000 + 100*t
the equation for Springfield can be written as:
S = 1000*(1.04)^t
we want to find the value of t that makes S(t) = G(t)
4000 + 100*t = 1000*(1.04)^t
(4000 + 100*t) = 1.04^t
4 + 0.1*t = 1.04^t
now, you can graph both of this equations (left side and right side) and see in wich value of t the graphs intersect eachother, or you also may use different values of t until the values are about the same for both sides, which is the thing i did with the equation:
4 = 1.04^t - 0.1*t
You will find that the correct value is t = 48
So we can assume that in year 1948 the populations will be about the same.

solve 2|x+1|=8
Answer:
x = 3 x = -5
Step-by-step explanation:
2|x+1|=8
Divide each side by 2
2/2|x+1|=8/2
|x+1| = 4
There are two solutions to an absolute value, one positive and one negative
x+1 = 4 x+1 = -4
Subtract 1 from each side
x+1 -1 = 4-1 x+1-1 = -4-1
x = 3 x = -5
Answer:
x=3 and -5
Step-by-step explanation:
to start with when you work with equations there will be two answers, no solution set or the answer will be 0. in this case there are two answers.
2/x+1/=8(first you remove all the things that are extra to the equation)
2 2
/x+1/=4 in this case it has two answers because 4 is greater than 0.
so you remove the bracket.
x+1=4 or x+1=-4
x=4-1 x=-4-1
x=3 x=-5

Pls answer
Answer:
-23
Step-by-step explanation:
x = -5 lies in the last piece
h(-5) = 4(-5) - 3
= -20 - 3
= -23
Step-by-step explanation:
Step 1: Find which piece-wise function it is in
Equation 1 → x < -7
Let x = -5 → (-5) < -7 ← False
Equation 2 → -7 ≤ x < -5
Let x = -5 → -7 ≤ (-5) < -5 ← False
Equation 3 → x ≥ -5
Let x = -5 → (-5) ≥ -5 ← True
Step 2: Find the value of h(-5)
[tex]h(-5) = 4x - 3[/tex]
[tex]h(-5) = 4(-5) - 3[/tex]
[tex]h(-5) = -20 - 3[/tex]
[tex]h(-5) = -23[/tex]
Answer: [tex]h(-5) = -23[/tex]
Plot the points (-8,7) and (5,7) on the coordinate plane below
Answer:
ok here you go
Step-by-step explanation:
i cant really plot them for you but i will help explain how to plot them.
the x-axis is the horizontal plane on the graph. the y-axis is the vertical plane on the graph. every coordinate has both a x and y point.
for you the x would be -8 and the y would be 7. first, you would go accross the x-axis to -8 and then go up to positive seven. you would be in the fourth quadrent in the graph. then you would do the same to the other pair. remember, (x,y)
