Answer:
14.94
Step by step:
25/30 = 83.333
.30x83 = 24.9
.60 x 24.9 = 14.94
Answer:
50
Step-by-step explanation:
Let's set the number as "x". So, 30% of x is 25. We can then write this equation.
30% * x = 25
Change 30% to a decimal
0.3 * x = 25
Divide both sides by 0.3
x = 83 and 1/3
Then, to find 60% of this number, write this equation.
60% * 83 1/3 =
0.6 * 83 1/3 =

32 km 24 km What is the length of the hypotenuse? C = kilometers
Answer:
40 kilometers
Step-by-step explanation:
the hypotenuse is a² + b² = c²
so first we have to get 32 and 24 into ²
32² = 1024 (32 × 32)
24² = 576 (24 × 24)
1024 + 576 = 1600
now we need to find the square root of 1600
√1600 = 40 (calculator)
therefore, the hypotenuse is 40 kilometers

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

It costs Eduardo 2 d 3 dollars to go to the carnival for d days. How many dollars does the carnival cost if Eduardo goes for d 5 days?
Answer:
$250
Step-by-step explanation:
Given: Cost for d days carnival = $2d^3 .....(i)
where d is number of days
Now we have to calculate the total cost incured for 5 days of carnival
we can simply put d = 5 in above equation (i)
= 2×5^3 = 2×125 = $250.
Therefore carnival cost if Eduardo goes for d 5 days = $250

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.What is 0.68 expressed an a fraction in simplest form with both the 6 and 8 repeating

i need the mean, median, mode, and range
Answer:
the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15
Step-by-step explanation:
the mode is 5 and 2 because they both occur the most often
The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5
the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25
the range is 15 because the range is the diff between the highest and lowest value

The number of minutes spent talking on the phone, m, and the amount of a cell phone bill, a. What is the independent variable
ILL BRAINLIEST YOU IF YOU GET IT RIGHT
explanation please
Answer:
[tex]\boxed {\boxed {\sf D. \ x=20}}[/tex]
Step-by-step explanation:
If line m and line r are parallel, the two angles must be congruent, because they are alternate interior angles. Notice how the 2 lines and the transversal form a backwards "Z" and the angles are in the inner corners.
So, if the angles are congruent, we can set them equal to each other.
3x-357x-115[tex]7x-115=3x-35[/tex]
Now, solve for x by isolating the variable. First, move all the constants to one side and the terms with variables to another.
115 is being subtracted and the inverse of subtraction is addition. Add 115 to both sides.
[tex]7x-115+115=3x-35+115\\7x= 3x+(-35+115) \\7x=3x+80[/tex]
3x is being added and the inverse of addition is subtraction. Subtract 3x from both sides.
[tex]7x-3x=3x-3x+80 \\4x=80[/tex]
x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
[tex]4x/4=80/4\\x=20[/tex]
If the lines are parallel, then x=20 so the angles are congruent.
please help i don’t understand
Answer:
18.38Explanation:
since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!

The number of students who took more than 45 minutes to complete their homework is 11.
What is a stemplot?A stem-and-leaf display, also known as a stem-and-leaf plot, is a technique used to visualize the shape of distribution by displaying quantitative data in a graphical fashion, similar to a histogram.
For the given stemplot the number of students who took more than 45 minutes to complete their homework can be calculated by counting the number of observations that are more than 45.
Therefore, the observations that are more than 45 are 48, 49, 51, 53, 53, 53, 53, 55, 60, 60, and 60.
Hence, the number of students who took more than 45 minutes to complete their homework is 11.
