Answer: C
Step-by-step explanation:
The arc length, s, equals the radius, r, times the central angle, θ, given in radians. (In shorthand, s=r⋅θ.) If r=5 cm and θ=6 radians, the arc length is 5 cm⋅6=30 cm. If r=7 cm and θ=5 radians, the arc length is 7 cm⋅5=35 cm. If r=9 cm and θ=4 radians, the arc length is 9 cm⋅4=36 cm. An angle of 180∘ is π radians, or about 3.14. If r=10 cm, the arc length is 10 cm⋅3.14=31.4 cm. Of these choices, the longest arc is 36 cm.

Six times a number increased by 26 is 296
What is the number?
Answers
Answer:
x = 45
Step-by-step explanation:
6x+26 = 296
6x+26-26 = 296-26
6x = 270
x = 45
Answer:
45
Step-by-step explanation:
Write the equation:
6n+26= 296
Subtract 26 from both sides:
6n+26-26= 296-26
Simplify:
6n= 270
Divide 6 by each side to get n by itself:
6n/6= 270/6
Simplify:
n= 45
You roll two number cubes. What is the probability of rolling double threes?
Answers
The probability of rolling double threes with two number cubes is calculated by multiplying the likelihood of each die showing a three independently, which is 1/6. Since each die is independent, the combined probability is 1/6 x 1/6 or 1/36.
When rolling two number cubes, often referred to as dice, the probability of rolling double threes is determined by considering the likelihood of each event occurring independently. Each die has six faces, so the probability of rolling a three-on-one die is 1/6. Since the outcome of rolling the second die is independent of the outcome of the first die, its probability of showing three is also 1/6.
The combined probability of both independent events occurring—that is, rolling a three on both dice—is found by multiplying the probabilities of the individual events. This means the probability is 1/6 multiplied by 1/6, which equals 1/36. So, the chance of rolling double threes is 1/36.
If we were discussing a different combination, such as rolling a one and a three, we would add the probability of the first die rolling a one and the second a three to the probability of the first die rolling a three and the second a one. But in the case of double threes, there is only one possible outcome that meets the criteria (a three on the first die and a three on the second) and therefore only one product of probabilities to consider.

Hope it will help u..
Answer and Step-by-step explanation:
Whenever we have a fractional exponent, the numerator is always going to be the exponent, and the denominator will be the root.
Here, the numerator is 4, so we taking 343 to the fourth power. At the same time, since the denominator is 3, we are taking the cube root of 343. Thus, we can write the expression as:
[tex]\sqrt[3]{343^4}[/tex]
We want to simplify this. We need to complete both operations, but it doesn't matter what order we do them in. In fact, I would do the cube root first because that won't lead to gigantic numbers:
[tex](\sqrt[3]{343} )^4=7^4=2401[/tex]
Thus, the answer is, I believe, 2401 (although it's not in radical form, the problem asked for the simplified answer, which is this).

Marsha has two numbers, $a$ and $b$. When she divides $a$ by 70 she gets a remainder of 64. When she divides $b$ by 105 she gets a remainder of 99. What remainder does she get when she divides $a+b$ by 35?
Answers
To find the remainder when Marsha divides a+b by 35, substitute the values of a and b into the expression and simplify to find that the remainder is 163.
Explanation:To find the remainder when Marsha divides a + b by 35, we need to consider the individual remainders when a is divided by 70 and b is divided by 105. Since Marsha gets a remainder of 64 when dividing a by 70, we can say that a = 70n + 64, where n is a positive integer. Similarly, since Marsha gets a remainder of 99 when dividing b by 105, we can say that b = 105m + 99, where m is a positive integer.
Now, substitute the values of a and b into the expression a + b and simplify:
a + b = (70n + 64) + (105m + 99) = 70n + 105m + 163
Now, divide a + b by 35 to find the remainder. Since both 70 and 105 are divisible by 35, we can simplify the expression further:
a + b = 35(2n + 3m) + 163
The remainder when dividing a + b by 35 is therefore 163.

Answers
Answer:
A = [- 2Bl + U^2 +/- √((2BL - U^2)^2 - 4B^2L^2) ] / 2L
Step-by-step explanation:
L = U^2A / (A + B)^2
U^2 A = L(A^2 + 2AB + B^2)
U^2 A = LA^2 + 2ABL + B^2L
LA^2 + 2ABL - U^2A + B^2 L = 0
LA^2 + (2BL - U^2)A + B^2L = 0
Using the quadratic formula
A = [- (2BL - U^2) +/- √[(2BL - U^2)^2 - 4*L*B^2L] / 2L
A = [- 2BL + U^2 +/- √[(2BL - U^2)^2 - 4B^2L^2) ] / 2L

Answers
Answer:
1. 0.83 = 83%
2. 6.1% = 0.061
Step-by-step explanation:
The answer in number one is because when you're trying to find a percentage from a decimal, all you have to do is multiply your decimal by 100, this is because a percentage is always out of 100.
The answer in number two is exactly the opposite, all you have to do is divide by 100 if you are trying to find your decimal from a percentage.
The decimal number 0.83 is equivalent to 83% when expressed as a percentage, and the percentage 6.1% can be written as 0.061 when converted into a decimal.
Explanation:To transform a decimal to a percentage, you need to multiply the decimal by 100. So, the statement 'The large tanks made up 0.83 of their sales last quarter' can be rewritten as 'The large tanks made up 83% of their sales last quarter'.
In order to transform a percentage into a decimal, you divide the percentage by 100. Therefore, the statement 'The kicker attempted 6.1% of the field goals he tried during away games' can be rewritten as 'The kicker attempted 0.061 of the field goals he tried during away games'.

Step-by-step explanation:
4x-7y=15 and 5x-2y=12
Answers
Presumably we're being asked to solve the system.
4x - 7y = 15
5x - 2y = 12
We don't really have any common factors among the coefficients of x, or among the coefficients of y, so we can do the general thing. To eliminate y multiply the first equation by (typically the absolute value of) the coefficient of y in the second equation and vice verse, then add or subtract equations to eliminate.
First equation times 2:
8x - 14y = 30
Second equation times 7:
35x - 14y = 84
Subtract,
27x = 54
x = 54/27 = 2
2y = 5x - 12 = 10 - 12 = -2
y = -1
Answer: x=2, y = -1
Check:
4(2)-7(-1)=8+7=15, good
5(2) -2(-1) = 10 + 2 = 12, good

If you do enough of these 2x2 linear systems you can learn to just write down the answer. I usually remember the matrix inverse, but if you haven't gotten there you can just remember the pattern:
ax + by = c
dx + ey = f
has solutions
x = (ce-bf)/(ae-bd), y = (a f-cd)/(ae-bd)
4x - 7y = 15
5x - 2y = 12
has solutions
denom = ae-bd = 4(-2) - (-7)(5) = 27
x = (15(-2) - (-7)(12))/27 = (-30 + 84)/27 = 2
y = (4(12)-15(5))/27 = (48-75)/27 = -27/27 = -1
Answer:
Step-by-step explanation:
4x-7y=15
Add '-7y' to each side of the equation.
Add '2y' to each side of the equation.
5x + -2y + 2y = 12 + 2y
Combine like terms: -2y + 2y = 0
5x + 0 = 12 + 2y
5x = 12 + 2y
Divide each side by '5'.
x = 2.4 + 0.4y
Simplifying
x = 2.4 + 0.4y
4x + 7y + -7y = 15 + -7y
Combine like terms: 7y + -7y = 0
4x + 0 = 15 + -7y
4x = 15 + -7y

What is the product of a^2/5(10)
Answers
Answer:
[tex]\frac{a^{2} }{10}[/tex]
Step-by-step explanation:
5*10 = 50. 50 = 25+25. The sqrt of 25 is 5, so 2 5's make 10.
The calculation of the product [tex]a^2/5(10)[/tex] involves squaring the base 'a', then dividing by 5 and finally, multiplying by 10. The solution will depend on the given value of 'a'.
Explanation:The question is asking for the product of [tex]a^2/5(10),[/tex] neglecting any typos. Here, we are assuming that the exponent 'a' in [tex]'a^2[/tex]' is the base, which is usually a positive integer. Using the given values, the expression becomes:
[tex]10 \times (a^2 / 5)[/tex]
To simplify this expression, we first square the base 'a'. If for example, 'a' is equal to 5 (the square of 5 is 25), the expression can be rewritten as:
10 * (25 / 5)
The final calculation becomes: 10 * 5 equaling 50 as the final answer. Please note that this example is strictly for illustrative purposes and the solution will vary according to the provided value of 'a'. The concept underlying the problem is exponentiation, multiplication, and division.

A line plot is a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data.
The main difference between a line plot and a line graph is that the line plot shows the frequency of number within a set, and the line graph shows the value of one variable relative to another.The number of dots in a line plot will be equal to the number of data points.
Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.
Question
Mosi is putting together his monthly budget and would like to know how much he makes in a month. His annual net salary is
$52,000. What is his monthly pay rate, rounded to the nearest dollar?
Answers
Final answer:
Mosi's monthly pay rate, calculated from his annual net salary of $52,000 and divided by 12 months, is $4,333 when rounded to the nearest dollar.
Explanation:
To calculate Mosi's monthly pay rate from his annual net salary, we need to divide his total annual net income by the number of months in a year. Since Mosi's annual net salary is $52,000, we perform the following calculation:
Monthly Pay Rate = Annual Net Salary ÷ Number of months in a year
Monthly Pay Rate = $52,000 ÷ 12
The result is a monthly pay rate of $4,333.33. However, the question asks us to round to the nearest dollar. Therefore, Mosi's monthly pay rate is $4,333 when rounded to the nearest dollar.
