a chord subtends an angle of 34 at the center of a circle of radius 4cm find the length of the chord (take =22/7)
Answers
Answer:
2.34 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle at the centre (θ) = 34°
Radius (r) = 4 cm
Length of chord (C) =?
The length of the chord can be obtained as follow:
C = 2rSine(θ/2)
C = 2 × 4 × Sine(34/2)
C = 8 × Sine 17
C = 8 × 0.2924
C = 2.34 cm
Therefore, the lenght of the chord is 2.34 cm.

A school luncheon made $630. Adult tickets cost $11 each and child tickets cost eight dollars each. The number of children was half the number of adults. How many of each ticket were sold?
Answers
a = adult tickets
c = child tickets
Now let’s set up a system of equations:
11a + 8c = 630
c = 1/2a (this can be confusing to some people but the CHILDREN TICKETS = HALF THE ADULT TICKETS)
Ok now we have to solve this:
11a + 8c = 630
c= 1/2a [you can solve this system of equations using substitution!]
11a + 8(1/2a) = 630
11a + 4a = 630
15a = 630
a = 42 (now we know our a value and we can plug that in to find c!)
c = 1/2a
c = 1/2(42)
c = 21
you can check this by plugging in your c and a value into both equations! I hope this helps! :)
Answer: a=42, c=21

If the simple interest on $7,000 for 5 years is $2,800, then what is the interest rate?
Answers
Answer:
8%
Step-by-step explanation:
Solving our equation
r = 2800 / ( 7000 × 5 ) = 0.08
r = 0.08
converting r decimal to a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to
accumulate simple interest of $ 2,800.00
from a principal of $ 7,000.00
over 5 years is 8% per year.

Step-by-step explanation:
The question is asking you to complete the congruence statement. In a congruence statement, the corresponding angles must be in the same order they are in, in the first half of the statement. In the first triangle <M=79, <N=60, and <O=42. So the other half must be in this same order. In the other triangle <R=79, <S=60, and <T=52, which is why the answer is RST.
John began his job making $125 the first week. After that he ws paid $6.25 per hour. Write the equation in slope intercept form to represent the situation.
Answers
Answer:
y=6.25x+125
Step-by-step explanation:
Given that,
John began his job making $125 the first week. After that he was paid $6.25 per hour.
Here $125 is fixed and $6.25 increase per hour. It means we can write the equation as follows :
y = 125 + 6.25 x
The general equation for the slope-intercept form is given by :
y = mx+x
m is slope
So, the equation in slope intercept form is given by :
y=6.25x+125
Hence, this is the required solution.
a) y= 0.05x + 16
b) y= 6.25x + 125
c) y= 2x + 10
d) y= 3x + 5
Answer: B) y = 6.25x + 125

[tex]\color{plum}\tt2x + 7° = \underline{65} \: degrees[/tex]
Steps to derive the correct solution :The exterior angle corollary states that the measure of a triangle's exterior angle is the sum of the opposite interior angles of the exterior angle.
Which means :
∠36° + ∠x° = ∠(2x + 7)°Let us solve this equation to find the measure of the exterior angle :
[tex] =\tt 2x + 7 = 36 + x[/tex]
[tex] = \tt2x + 7 - x = 36[/tex]
[tex] =\tt x + 7 = 36[/tex]
[tex] = \tt \: x = 36 - 7[/tex]
[tex] =\tt x = 29[/tex]
Thus, the measure of ∠x = 29°Then, the measure of the exterior angle :
[tex] = \tt2 \times 29 + 7[/tex]
[tex] = \tt58 + 7[/tex]
[tex] = \tt65[/tex]
Thus, the measure of the exterior angle 2x+7 = 65°
Let us check whether or not we have found out the correct measure of each angle by placing 29 in the place of x:
[tex] = \tt2 \times 29 + 7 = 36 + 29[/tex]
[tex] =\tt 58 + 7 = 36 + 29[/tex]
[tex] = \tt65 = 65[/tex]
Since the measures match we can conclude that we have found out the correct value of each angle.
Therefore, ∠2x + 7° = 65°

Step-by-step explanation:
Ally gives her sister = 1/5 stickers
Ally gives her cousin = 1/5 of the remainder stickers
Assume Number of sticker Ali has = 1
Remainder after giving stickers to her sister = 1 - 1/5 = 4/5
Number of stickers she gave her sister = [tex]\frac{1}{5}\times\frac{4}{5}[/tex]
=[tex]\frac{4}{25}[/tex]
Sticker she has = [tex]1-\frac{1}{5}-\frac{4}{25}[/tex]

Find the degree measure of each angle in the triangle.
Answers
Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.
