Triangle abc is an isosceles triangle in which angle b = angle c and l and m are points on ab and ac respectively such that lm parallel to bc. If angle a = 50 degree find angle lmc
Answer:
∵ ABC is an isosceles triangle
∵ m∠b = m∠c
∴ m∠b and m∠c = 180 - m∠a/2
= 180 - 50/2
= 130 /2
= 65°
∵ ∠c and ∠AMI are corresponding angles
∵ m∠AMl = m∠c = 65° (1)
From (1)
∵ ∠AMC is striaght angle
∴ m∠IMC = 180 - m∠AMI
m∠IMC = 180 - 65
m∠IMC = 115°
Answer = 115°

Answer:
$8553.87
Step-by-step explanation:
Formula = Initial amount x (1+(%/100) squared by (t) years or time.
7600 x 1.03^4 =8553.86696 = $8553.87 nearest penny rounded up.
To reverse such amount if given percentage (%) time (t) and (nv) new value to question. We realise it has asked the opposite in asking to find the initial investment it may say what Did Dan initially or originally invest? we would divide new amount by (1+) (%/100)^(t) and percentage and show like this;
8553.87 / 1.03^4= 7600.0027 = $7200 for initial investment.
However the question asks for total new value of investment after 4 years.
So the first formula is shown and shows answer to be $8553.87

What is (0,5) and (2,14) in slope intercept form
Answer:
y = 9/2x + 5
Step-by-step explanation:
ok first find the slope with equation (x2 - x1 over y2 - y1)
14 - 5 = 9/
2 - 0 2
so 9/2 is your slope so now pick one of the points (let's do 0, 5) and plug that into the slope intercept form (y = mx+b)
5 = 9/2(0)+b
9/2 • 0 = 0 so b = 5
so the answer is y = 9/2x + 5. hope this helps!

Answer:
[tex]\frac{1}{9}[/tex]
Step-by-step explanation:
Note the bar above 1 means 1 is repeating , that is
0.111..
We require 2 equations with the repeating digit placed after the decimal point
let x = 0.111.... (1) Multiply both sides by 10
10x = 1.111... (2)
Subtract (1) from (2) thus eliminating the repeating digit
9x = 1 ( divide both sides by 9 )
x = [tex]\frac{1}{9}[/tex]

AB=4cm BC =5cm CD =8cm .Calculate the area of rectangle BCDE
Step-by-step explanation:
1.2
area of triangle = ½ × base × height
so,
height = 5cm
base = 4cm
now,
→ 1/2 × 4 × 5
→ 2 × 5 = 10 cm²
therefore, area of the ∆AED is 10cm².
1.3
area of rectangle = l × b
length = 8cm
breadth/width = 5cm
now,
area of BCDE
→ 8 × 5 = 40 cm²
now,
area of,
→ ABCD = BCDE - ∆AED
→ ABCD = 40 - 10 = 30
therefore, required area of ABCD is 30cm².
hope this answer helps you dear...take care and may u have a great day ahead!
Joseph traveled from Boston to Framingham at 50 mph and then back to Boston at 40 mph, What was Joseph average speed on the round trip? (its not 45mph just to let you know)
Answer:
44.44 mph
Step-by-step explanation:
Since we are given 50 from the start, and 40 at the end, we will add 50 and 40.
50 + 40 = 90
Then, Divide the result by 2.
90 ÷ 2 = 45
Here is the tricky part: we are not done!
Don't be mistaken by the question. Some people may think the answer is 45mph because that is what it is rounded up, however, the question did not ask for the answer rounded up.
This is a round trip, so reduce this to the nearest value in both tenths and units. Hence, it would be 44.44.
Graph the line that passes through the two points.(1, 5/2), (−1/2,−1/4)
Answer:
To find the slope of a line, simply use the slope formula [(y2-y2)/(x2-x1)].
To find the y-intercept, simply plug in point values to solve for b.
The line that passes through the two points (1, 5/2) and (-1/2,-1/4) is y=1.8x+0.7.
The given coordinate points are (1, 5/2) and (-1/2,-1/4).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
Substitute (x1, y1)=(1, 5/2)=(1, 2.5) and (x2, y2)=(-1/2, -1/4)=(-0.5, -0.25) in slope formula, we get
Slope =(-0.25-2.5)/(-0.5-1)
= -2.75/(-1.5)
= 1.8
Put m=1.8 and (x, y)=(1, 2.5) in y=mx+c, we get
2.5=1.8×1+c
c=0.7
So, equation is y=1.8x+0.7
Hence, the line that passes through the two points (1, 5/2) and (-1/2,-1/4) is y=1.8x+0.7.

2x^3-3x^2+kx-1 is divided (x-1),the remainder is 2 find k
Answer:
k = 4
Step-by-step explanation:
if f(x) is divided by (x - h) then f(h) is the remainder
f(x) = 2x³ - 3x² + kx - 1
divided by (x - 1) , so h = 1 , then
2(1)³ - 3(1)² + k(1) - 1 = 2
2 - 3 + k - 1 = 2
- 2 + k = 2 ( add 2 to both sides )
k = 4
Emily has a piggy bank that contains 30 coins in dimes and nickels. Their combined value is $2.10. How many coins of each kind are there?
Answer:
Step-by-step explanation:
Though we can divide this second equation by five and combine, let's multiply the first equation by five and subtract it from the second...
10d + 5n = 210
-(5d + 5n = 150)
and we get
5d = 60
d = 12 dimes
n = 30-12 = 18 nickels
The graph of which inequality has its vertex at (2 1/2, 5)?
The correct answer to this is y>|2x-5|+5.
My question is where did the 2 1/2 come from in the vertex?
Answer:
77777
Step-by-step explanation:
In this case, the vertex is the lowest point of the V shaped curve.
The goal is to get the stuff inside the absolute value (the 2x-5) to be as small as possible, so we can get to the lowest point. In terms of absolute value, we want the 2x-5 to be equal to 0
This allows us to set up the equation below and solve for x.
2x-5 = 0
2x = 5
x = 5/2
x = (4+1)/2
x = 4/2 + 1/2
x = 2 + 1/2
x = 2 & 1/2

Solve the inequality 2 (m+3) +1 > 23
Answer:
m>8
Step-by-step explanation:
The first step will be to distribute the 2, so that the equation becomes 2m + 6 + 1 > 23.
From here we should combine like terms, which just means adding 6 and 1, so that the equation is now 2m+7>23. Now, we just subtract 7 on both sides, which brings leave us with 2m > 16.
Lastly dividing by 2 on both sides, the answer is m>8

79.6 is the mean of given set of scores calculated by adding all the given scores and dividing it by number of scores which is 10.
To find the mean (average) of a set of scores, you need to add up all the values and then divide by the total number of values.
Let's calculate the mean of the math test scores you provided:
Math test scores: 92, 52, 80, 54, 75, 62, 78, 78, 95, 80
Add up all the scores:
92 + 52 + 80 + 54 + 75 + 62 + 78 + 78 + 95 + 80
= 796
Find the total number of scores:
There are 10 scores in the set.
Calculate the mean:
Mean = Sum of scores / Total number of scores
Mean = 796 / 10
Mean = 79.6
So, the mean of the math test scores is 79.6.
