Hi if you answer please explain how you got the answer thanks! :)
Answer:
B: 60,000
Step-by-step explanation:
Since there was a total of 200,000 votes, we can create this equation, since we also know the ratio between the two candidates:
7x + 3x = 200,000
x can be seen as a common factor between the two candidates that can be used to express their difference
We can now further simplify this equation by combining like terms and solving for x:
10x = 200,000
x = 200,000/10
x = 20,000
Now, to find the total number of votes cast for Bob Tanks, we multiply x by 3, since it says that Julie Sanders won by a ratio of 7:3, which means she had 7 in the ratio and Bob had the 3.
3x = 3(20,000) = 60,000
The answer is B: 60,000.
Answer: 60,000
Step-by-step explanation:
The easiest way to solve this problem is to use equations
Since we know the ratio of Julie's votes to Bob's votes is 7:3 and the total is 200,000 we can use this equation 200,000 (number of votes) = 7x(Julie's votes) + 3x(Bob's votes)
After you solve it you get x=20,000
Then,
You put that back into Bob's votes and you get 60,00
Hope this helps :)

Find the value of x
Answer:
1
Step-by-step explanation:
As per circle theorem rule, ∠GDE is twice than ∠GFE
10x +94 = 2 × (x+51)
10x + 94 = 2x + 102
8x = 8
x = 1
∠GDE= 10x+94° = 104°
∠GFE= x + 51° = 52°

In a normal distribution, 99.7% of the data fall within how many standard
deviations of the mean?
A. Two standard deviations
B. One standard deviation
C. It cannot be determined from the given information.
D. Three standard deviations
Answer: Three standard deviation
Step-by-step explanation:
In a normal distribution, 99.7% of the values falls within three standard deviation from the mean.
What is empirical rule?
Empirical rule states that for a normal distribution, 68% of the values falls within one standard deviation from the mean, 95% of the values falls within two standard deviation from the mean and 99.7% of the values falls within three standard deviation from the mean.
Hence:
In a normal distribution, 99.7% of the values falls within three standard deviation from the mean.

A list of 5 numbers is shown below.
0, 3, 7, -6, -12.3
Which set contains all the numbers in the list?
A integers
B whole numbers
C natural numbers
D rational number
Answer:
D. Rational Number
Step-by-step explanation:
Integers are defined as all whole numbers, positive and negative, including 0. Since in the list there is a number that is not whole, A is not the correct answer choice.Whole numbers are all positive numbers (including 0) without decimals or fractions. Since the list has a number that is not a whole number, along with two that are negative, B is also not correct.Natural numbers are all positive numbers (excluding 0) without decimals or fractions. Since there is a 0 in the list, C is not correct.Rational numbers are all numbers that can be simplified into a ratio with 2 integers (i.e. π and e are not rational). Since every number on the list can be put into this category, answer choice D is correct.a cylinder has a diameter of 6cm and a height of 3 cm what is the surface area of the cylinder?

A square is attached to a semicircle to make the figure shown in the diagram below .
if the radius of the semicircle is 4 meters ,what is the aproximate area of the figure .
Answer:
C) 89.12 m^2
Step-by-step explanation:
You can find the area of this figure by finding the areas of both shapes (semicircle and rectangle) then adding both areas.
To find the area of a semicircle, use this formula:
1/2πr^2 (1/2 x 3.14 x radius x radius)
Here, this radius is 4.
Now, we just plug in the numbers.
[3.14 is always used for π (pi)].
1/2 x 3.14 x radius x radius
↓
1/2 x 3.14 x 4 x 4 = 25.12
25.12 is the area of the semicircle.
Now, we must find the area of the square.
SQUARES ARE HAVE EQUAL SIDES, SO TO FIND THE AREA, WE SIMPLY MULTIPLY A SIDE LENGTH BY ITSELF TWICE.
8 x 8 = 64.
Now that we have both areas, we add to find the area of the figure.
25.12 + 64 = 89.12
Therefore, the area of this figure is 89.12 meters^2.
Sphere A has radius of 2 cm. Sphere B has radius of 4 cm. (=433 V = 4 3 π r 3 use 3.14 for π . ) a) The volume of sphere A is b) The volume of sphere b is c) The volume of Sphere B is_______times greater that the volume of Sphere A.
Answer:
volume of Sphere B is 8 times greater than the volume of Sphere A
Step-by-step explanation:
Sphere A: V = 4π (2^3)/3 = 32π/3
Sphere B: V = 4π (4^3)/3 = 4π(64)/3 = 256π/3
volume of Sphere B / volume of Sphere A = (256π/3)/(32π/3) = 8

what is calculating the area of a triangle
Answer:
bh/2
Step-by-step explanation:
So first, you have to multiply the base times height and you get a value. Then, you divide the value by 2. For example, a triangle that has a base of 3 and height of 4, you would multiply 4x3 which is 12 and then divide by 2 which is 6. Hope this helps :)
Let p(x)=90/9+50e^−x.
What is p(−2)?
Enter your answer, rounded to the nearest tenth, in the box.
p(x) = 90 / (9 + 50 * e^(-x))
e = 2.718, so we can use e = 2.7 as a quick substitute
p(3) =>
90 / (9 + 50 * e^(-3)) =>
90 / (9 + 50 * 2.7^(-3)) =>
90 / (9 + 50 / 2.7^3) =>
