To convert an integer to a fraction you must choose an expression that does not alter the numerical value. You can do this with multiples of the number, for example, for 100:
100/1 = 200/2 = 300/3 = 400/4 = 100
The numerical value is not altered and the result will always be 100
Another example, for 500:
500 = 500/1 = 1000/2 = 1500/3 = 2000/4

What is the sum of a° + c°?
300°
120°
230°
240°
Answer:
300°
Step-by-step explanation:
Given from the diagram:
Angle a° = 180° (Single angle on a straight line)
Angle c° + 60° = 180° (Sum of angles on a straight line)
Angle c° = 180° - 60° = 120°
Angle a° + c° = 180° + 120° = 300°
Answer:
a + c = 300°
Step-by-step explanation:
a = 180°
c = 180° - 60° = 120°
a + c = 180° + 120° = 300°
What is the area of the trapezoid?
A. 120 cm squared
B. 128 cm squared
C. 144 cm squared
D. 176 cm squared
Answer: B. 128
Step-by-step explanation:
According to the picture, the parallel side of the trapezoid are a= 10 cm and b = (10+4+8) cm= 22 cm respectively
The perpendicular distance between these parallel sides, h = 8 cm
We know,
Area of trapezoid = {{(a+b)×h} ÷ 2
={(10+22)×8}÷2
=128

a²+b²=c²(12)²+(x)²=(x+2)²...substitute values 144+x²=x²+4x+4...squaring it144+x²-(x²+4x+4)=0...shift x²+4x+4 to the left144+x²-x²-4x-4=0...equate the similar values140-4x=0....move 140 to the right to solve for it-4x=-140....divide both sides by 4x=35.... finally we get 35.If you have any questions ask me thx
Anjali was keeping track of how far she walked. She walked 1 1/10 miles on Monday, 4 4/5 miles on Wednesday, and 2 1/4 on Friday. What was the total distance she walked? show your work using decimals. pls help
Answer:
8.15 miles
Step-by-step explanation:
Monday: 1 1/10 miles = 1.1
Multiply by 10 to get to 100
Wednesday: 4 4/5 miles = 4.8
Multiply by 20 to get to 100
Friday: 2 1/4 miles = 2.25
Multiply by 25 to get to 100
1.1 + 4.8 + 2.25 = 8.15 miles
A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the true proportion is 0.03. If 476 are sampled, what is the probability that the sample proportion will be less than 0.04
The probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.
The true proportion (p) is given to be 0.03.
Therefore, Mean (μ) = p = 0.03.
The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.
Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.
Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.
Since, we are asked to find the probability that the sample proportion is less than 0.04, we using our calculator, enter as following:
Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.
Thus, the probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

You have 3 quarters, 5 dimes, 7 nickels, and some pennies.-if the ratio of dimes to the total number of coins you ha e is 1:4, how many pennies are there?
The number of pennies there are, given the types of coins you have are 5 pennies.
How to find the number of pennies ?Since we have 5 dimes, we can set up the equation:
1/4 = 5/x
where x is the total number of coins.
Solving for x, we can cross-multiply:
1x = 45
x = 20
So we have a total of 20 coins.

A radio telescope has a parabolic surface, as shown below.
A parabola opening up with vertex at the origin is graphed on the coordinate plane. The height of the parabola from top to bottom is 1 meter, and its width from left to right is 20 meters.
If the telescope is 1 m deep and 20 m wide, how far is the focus from the vertex?
The height of the telescope of 1 meter and width of 20 meters gives a distance of the focus from the vertex of 25 meters.
Which method can be used to find the distance between the focus and vertex?Given that the vertex is at the origin, we have;
(h, k) = (0, 0)
The equation of a parabola is presented as follows;
(x - h)² = 4•p•(y - k)
x² = 4•p•y
When x = 10, y = 1
Therefore;
p = 10² ÷ 4 = 25
The focus of the parabola = (h, k + p)
Which gives;
The focus of the parabola = (0, 0 + 25) = (0, 25)
The distance of the focus from the vertex is therefore;
d = 25 - 0 = 25The distance of the focus from the vertex is 25 metersLearn more about the parts of a parabola here:

36. Dennis set off from Town A at 10 A.M., driving at an average rate of speed of 52 mph. He reached
Town B at 2 PM. If William set off 1 hour 25 minutes earlier than Dennis and took the same route
at an average rate of speed of 40 mph., at what time would William reach Town B?
The time William would arrive in town B IS 1 : 47 pm.
What time will William arrive in town B?The first step is to determine the distance and the time of Dennis's travel.
Time = 14 hours (2 pm + 12) - 10 hours = 4 hours
Distance = time x average speed
4 x 52 = 208 miles
The second step is to determine the time of William's travel:
Distance / average speed = time
208 / 40 = 5.20 = 5 hours 12 minutes
Time William left for the trip = 10 am - 1 hour 25 minutes = 8 :35am
Time he would reach town B = 8 : 35am + 5 hours 12 minutes = 13 hours 47 minutes = 1 : 47 pm

What is the scenario under the balloon game?The rule of play are:
This is a classic game with simple rules which are:
Each player to hit the balloon up and it bonce into the air but when one should not allow it to touch the ground.,Players would be tied together in twos and they will juggle a lot of balloon and it have to be more than 1 balloon with one of their hands tied to their back.A scenario of the worksheet game whose expected value is 0 is given below:
Assume that it costs about $1 for a player to play the billon game and as such, if the player hits a balloon, they will be given $3. what can you say. Can you say that it this game is fair or not? and who has the biggest advantage.
Solution
Note that a game is ”fair” if the expected value is said to be 0. When a player is said to hits a balloon, their net profit often increase by $4. So when the player do not hit a balloon, it drops to $1.
(4)(0.313) + (-1)(0.313)
