Answer:
At the end of 50 days , Amount of money = $2500x
where x is the value that added every day.
Step-by-step explanation:
Let daily amount added in 1 envelope = $x
As, we have 50 envelope,
so, daily added amount in 50 envelope = $ 50x
⇒ Each day , we add money = $ 50 x
After 50 day, it becomes $50×50x = $2500x
For example -
If we add $ 1 every day in each envelope
then ,
Total amount added in 50 envelope each day = $50×1 = $ 50
Then,
After 50 days,
Total amount = $ 50×50 = $2500
∴ we get
At the end of 50 day, total amount we have = $2500

This question is incomplete
Complete Question
If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches
a 33.4 inches
b. 35.6 inches
C. 37.5 inches
d. 39.3 inches
Answer:
d. 39.3 inches
Step-by-step explanation:
We are to find the Arc length of the circle
To solve the above question, the formula is given as:
Arc length = Central angle × radius
From the above Question, we are given:
Central angle = 5pi/6 = 5π/6
Radius = 15 inches
Hence,
Arc length = 5π/6 × 15 inches
Arc length = 235.61944901923448/ 6
Arc length = 39.26990817 inches
Approximately , the Arc length
= 39.3 inches.
Therefore, Option d is the correct answer.
What are the coordinates of point S"? (negative three-halves, nine-halves) (negative nine-halves, fifteen-halves) (nine-halves, negative three-halves) (negative fifteen-halves, 0)
Answer:
[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]
Step-by-step explanation:
The missing details are:
[tex]T= (0,4)[/tex]
[tex]M = (\frac{9}{4}, \frac{5}{4})[/tex] --- Midpoint of ST
Required
Determine the coordinates of S
To do this, we apply the mid-point formula:
[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
Where
[tex]M(x,y) = (\frac{9}{4}, \frac{5}{4})[/tex]
[tex]T(x_1,y_1) - (0,4)[/tex]
The equation becomes:
[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(0+x_2,4+y_2)[/tex]
[tex](\frac{9}{4},\frac{5}{4}) = \frac{1}{2}(x_2,4+y_2)[/tex]
Multiply through by 2
[tex]2*(\frac{9}{4},\frac{5}{4}) = 2*\frac{1}{2}(x_2,4+y_2)[/tex]
[tex](\frac{9}{2},\frac{5}{2}) = (x_2,4+y_2)[/tex]
By comparison:
[tex]x_2 = \frac{9}{2}[/tex]
[tex]4 + y_2 =\frac{5}{2}[/tex]
[tex]y_2 =\frac{5}{2}-4[/tex]
[tex]y_2 =\frac{5-8}{2}[/tex]
[tex]y_2 =-\frac{3}{2}[/tex]
Hence, the coordinates of S is:
[tex]S=(\frac{9}{2},-\frac{3}{2})[/tex]

A chess club with 45 members is electing a new president. Bob received 18 votes. What percentage of the club members voted for Bob?
Given:
A chess club with 45 members is electing a new president.
Bob received 18 votes.
To find:
The percentage of the club members who voted for Bob.
Solution:
We have,
Total number of members = 45
Votes received by bob = 18
Now, the percentage of the club members who voted for Bob is
[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]
[tex]\%=\dfrac{18}{45}\times 100[/tex]
[tex]\%=\dfrac{2}{5}\times 100[/tex]
[tex]\%=\dfrac{200}{5}[/tex]
[tex]\%=40[/tex]
Therefore, 40% of the club members voted for Bob.
This graph shows the distance vs. time relationship for the Lane 1 and Lane 2 turtles. Here are their equations:
Lane 1: d= 6+ 1t
Lane 2: d = 3t
Select all of the true statements.
(Select all that apply.)
1. The Lane 2 turtle is faster than the Lane 1 turtle.
2. At 3 seconds, the turtle in Lane 2 is 12 feet from the start.
3. At 12 seconds, the turtle in Lane 1 is 6 feet from the start.
4. The Lane 1 turtle has a head start.
Answer:
True statements are:
(i) The lane 2 turtle is faster than the lane 1 turtle.
(iv) The lane 1 turtle has a head start.
Step-by-step explanation:
Now we proceed to check the value of truth for each choice:
(i) The lane 2 turtle is faster than the lane 1 turtle.
Speed of the turtle is the slope of the linear function, the greater the slope, the faster the turtle. Hence, the lane 2 turtle is faster than the lane 1 turtle. (Answer: TRUE)
(ii) At 3 seconds, the turtle in Lane 2 is 12 feet from start.
Let the position of the turtle in Lane 2 be represented by [tex]d = 3\cdot t[/tex]. For [tex]t = 3\,s[/tex], then [tex]d = 3\cdot (3) = 9[/tex]. Hence, the turtle in Lane 2 is just 9 feet from the start. (Answer: FALSE)
(iii) At 12 seconds, the turtle in Lane 1 is 6 feet from the start.
Let the position of the turtle in Lane 1 be represented by [tex]d = 6 + t[/tex]. For [tex]t = 12\,s[/tex], then [tex]d = 6+12 = 18[/tex]. Hence, the turtle is 12 feet from the start. (Answer: FALSE)
(iv) The lane 1 turtle has a head start.
According to graph, Lane 1 turtle starts at a position of 6 feet, whereas Lane 2 turtle start at a position of 0 feet. Hence, Lane 1 turtle has a head start. (Answer: TRUE)

Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Answer:
£15000
Step-by-step explanation:
Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Giving the ratio of inheritance 5:3:2
5+3+2 = 10
Mary's ratio = 3
Marys share = £4500
Total share x can be gotten as thus
3/10 × x = 4500
3x/10 = 4500
3x = 45000
x = 45000/3
x = 15000
Hence £15000 was there in total

Hey! I'm confused on this question It's : 3/4 - 3/10
Answer:
9/20
Step-by-step explanation:
I hope this helps :)
Answer:
9/20
Step-by-step explanation:
In order to subtract fractions you need to find the least common denominator. Since the LCD is 20 (4 times 5 or 10 times 2) you need to multiply each fraction by 1 to get the denominators the same.
3/4 times 5/5 = 15/20
3/10 times 2/2 = 6/20
now you can subtract!
15/20 - 6/20 = 9/20
you can not simplify this, so your final answer is 9/20

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'?
Answer:
D. (2, -1)
Step-by-step explanation:
I took the test and got it right.
Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
If the point is in the second quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Triangle QRS is rotated 180° about the origin.
On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).
So, the coordinates of point S will be (2, -1).

Lines m and n are parallel. The measure of angle 6 is 55°.
What is the measure of angle 1?
35°
55°
125°
155°
Answer:155
Step-by-step explanation:
because they are parallel lines. If the angles differed even by 1°, eventually the lines would meet, therefore they would not be parallel.
Answer:
Firstly angle 6 and 2 are equal because of corresponding angles
so 6 = 2
Now angle 1 + 2 = 180 ( linear pair)
angle 1 = 180 - 55
1 = 125

Bryan has quarters and nickels in his piggy bank. He has three times as many nickels as he has quarters. If the total value of the coins is $12, find the number of nickels in the piggy bank.
Answer:
90
Step-by-step explanation:
Quarters , q = 25 cent
Nickel, n = 5 cent
3 times as many nickels as quarters;
n = 3q
Total value of coins = $12
n + q = $12
0.05n + 0.25q = 12
0.05(3q) + 0.25q = 12
0.15q + 0.25q = 12
0.40q = 12
q = 12 / 0.40
q = 30
n = 3q
n = 3(30)
n = 90
90 nickels
Which ratio represents the cotangent of angle B in the right triangle below?
A. 5/3
B. 3/5
C. 3/4
D. 4/3
Answer:
C. 3/4
Step-by-step explanation:
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
From the diagram
Opposite = x
Adjacent = 12
tan <B = x/12
Since cot <B = 1/tan <B
cot <B = 12/x
Get x using pythagoras theorem
x² = 20²-12²
x² = 400 -144
x² = 256
x = 16
Hence cot <B = 12/16
cot <B =3/4
