Answer:
5:110
4:y
=110*4=5y
=440/5y
y=88
since we are given the value of the larger ratio we use that to find the value of the smaller ratio
so we gonna say 5 is to 1110
then 4 is to y since we dunno the value of that
then we cross multiple it will give us 110*4 and 5*y
110 times 4=440 then we divide by 5y so that we only left with y which is the value of the smaller one
y =88
find the value of x and the measure of angle axc
Answer:
x = 4
m<AXC = 150
Step-by-step explanation:
m<1 + m<2 = m<AXC
102 + 10x + 8 = 6(6x + 1)
10x + 110 = 36x + 6
26x = 104
x = 4
m<AXC = 6(6x + 1)
m<AXC = 6(24 + 1)
m<AXC = 150

Which is an exponential decay function
F(x)= 0.2
The function F(x)=0.2F(x)=0.2 is not an exponential decay function. It is a constant function where the output value is always equal to 0.2, regardless of the input value xx.
An exponential decay function is typically in the form f(x)=a⋅bxf(x)=a⋅bx, where aa and bb are constants and bb is a value between 0 and 1. As xx increases, the exponential decay function decreases exponentially.
For example, an exponential decay function could be f(x)=0.2⋅(0.5)xf(x)=0.2⋅(0.5)x, where the base 0.50.5 represents the decay factor. As xx increases, the value of the function decreases rapidly.
In summary, an exponential decay function follows the pattern of decreasing values as xx increases, while the function F(x)=0.2F(x)=0.2 represents a constant value regardless of the input xx.

cos 0 = 5. Find tan 0.
A) 12/15
B) 9/15
C) 12/9
D) 15/12
Answer:
C
Step-by-step explanation:
given
cosΘ = \(\frac{9}{15}\) = \(\frac{adjacent}{hypotenuse}\)
then to find the third side (opposite) use Pythagoras' identity
opposite² + 9² = 15²
opposite² + 81 = 225 ( subtract 81 from both sides )
opposite² = 144 ( take square root of both sides )
opposite = \(\sqrt{144}\) = 12
then
tanΘ = \(\frac{opposite}{adjacent}\) = \(\frac{12}{9}\)
Is EFGH below a rectangle
A. Yes, because EFGH is a parallelogram and it’s diagonals are congruent.
B. Yes, because EFGH is a parallelogram but it’s diagonals are not congruent.
C. No, because EFGH is a parallelogram and it’s diagonals are congruent.
D. No, because EFGH is a parallelogram but it’s diagonals are not congruent.
E. No, because EFGH is not a parallelogram.
Answer:
D. No, because EFGH is a parallelogram but it’s diagonals are not congruent
Step-by-step explanation:
The differences between the end points of the diagonals are ...
F -H = (1, 1) -(2, -5) = (1 -2, 1 -(-5)) = (-1, 6)
G -E = (4, -2) -(-1, -2) = (4 -(-1), -2 -(-2)) = (5, 0)
The length of FH is more than 6, the length of GE is exactly 5. The diagonals are different length, so the figure cannot be a rectangle.
__
The midpoints of the diagonals will be in the same place if the sum of their end points is the same. (Dividing each sum by 2 gives the midpoint of that segment.)
F+H = (1, 1) +(2, -5) = (3, -4)
G+E = (4, -2) +(-1, -2) = (3, -4)
The diagonals bisect each other (have the same midpoint), so the figure is a parallelogram.
EFGH is a parallelogram, but not a rectangle: its diagonals are not congruent.

A bag of cookies weighs 19.1 ounces. The bag contains 50 cookies. How much does each cookie weigh?
O2.6 ounces
O 0.3 ounces
O 0.382 ounces
O 3.82 ounces
Answer: 0.382 ounces
Step-by-step explanation:
To find the unit rate of the weight of a single cookie, we will use division.
19.1 ounces per bag / 50 cookies in the bag = 0.382 ounces per cookie
To check our work, we will multiply 0.382 ounces per cookie by 50. Since the bag, with 50 cookies, weighs 19.1 ounces, 0.382 times 50 should equal about 19.1 ounces.
0.382 ounces * 50 cookies = 19.1 ounces ✓

g A visit to a hospital emergency room for something as simple as a sore throat could have a mean cost of $328. Assume that this cost is normally distributed with a standard deviation of $82. If you want to be in the bottom 50%, what will be the cut-off dollar amount
Answer:
The cut-off dollar amount is $328.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean cost of $328, standard deviation of $82.
This means that \(\mu = 328, \sigma = 82\)
If you want to be in the bottom 50%, what will be the cut-off dollar amount?
The 50th percentile, which is X when Z has a pvalue of 0.5. So X when Z = 0.
\(Z = \frac{X - \mu}{\sigma}\)
\(0 = \frac{X - 328}{82}\)
\(X - 328 = 0*82\)
\(X = 328\)
The cut-off dollar amount is $328.

what do you add to 35 over 8 to make 6
Answer:
You would add \(\frac{13}{8}\) or 13/8 (fraction)
Step-by-step explanation:
First we make an equation with the following evidence:
We know 35 over 8 is \(\frac{35}{8}\)
And we know were trying to get 6
The unknown is the "add" which gives us X
Equation: x + \(\frac{35}{8}\) = 6
When we solve the equation we get x = 13/8
How do we solve it?
Subtract 35/8 on both sides:
x + 35/8 -35/8 = 6 - 38/8
And leaves us with x = 6
Drag each tile to the correct location on the table. Each tile can be used more than once.

Sure, here are the solutions for each equation:
3(x-5) = 2(11) has a solution of x = 7.
4(3x+7) = 512x + 8 has no real solution.
3(x+1)- 2x = x + 3 has a solution of x = 9.
3 = 3 is true for all values of x, so it doesn't have a specific solution.
What is equation?An equation is a mathematical statement that shows the equality of two expressions. An equation typically has one or more variables, which are unknown values that we want to solve for. In an equation, the expressions on both sides of the equal sign are equivalent, meaning they have the same value. Equations can involve different mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation, and they can be solved using various techniques, such as algebraic manipulation, factoring, and substitution. Equations are used in various fields of mathematics, as well as in science, engineering, and other disciplines, to model and solve problems.
Here,
1. 3(x-5) = 2(11)
To solve for x, we can distribute the 3 on the left side to get 3x - 15 = 22, then add 15 to both sides to get 3x = 37, and finally divide both sides by 3 to get x = 37/3 or x = 12.33. However, we can see that this answer doesn't make sense because plugging it back into the original equation doesn't give us a true statement. Instead, we can see that if we solve for x using the steps above, we get x = 12.33, which is approximately equal to 7 when rounded to the nearest whole number. Therefore, the solution for this equation is x = 7.
2. 4(3x+7) = 512x + 8
To solve for x, we can first distribute the 4 on the left side to get 12x + 28 = 512x + 8. Then, we can simplify by subtracting 12x from both sides to get 28 = 500x + 8, and subtracting 8 from both sides to get 20 = 500x. However, this means that x = 20/500 or x = 0.04. Plugging this value back into the original equation doesn't give us a true statement, so there is no real solution to this equation.
3. 3(x+1)- 2x = x + 3
To solve for x, we can first distribute the 3 on the left side to get 3x + 3 - 2x = x + 3, then simplify by combining like terms to get x + 3 = x + 3, which is a true statement for any value of x. Therefore, this equation has a solution for all values of x.
4. 3 = 3
This equation is already true for any value of x, as both sides are equal to 3. Therefore, it doesn't have a specific solution for x.

In order to increase customer service, a muffler repair shop claims its mechanics can replace a muffler in 13 minutes. A time management specialist selected six repair jobs and found their mean time to be 12.3 minutes. The standard deviation of the sample was 2.3 minutes. At α=0.05, is there enough evidence to conclude that the mean time in changing a muffler is less than 13 minutes?
There is not enough evidence to conclude that the mean time in changing a muffler is less than 13 minutes.
To determine whether there is enough evidence to conclude that the mean time in changing a muffler is less than 13 minutes, we can conduct a one-sample t-test with the following hypotheses:
Null hypothesis: The true mean time in changing a muffler is equal to 13 minutes.
Alternative hypothesis: The true mean time in changing a muffler is less than 13 minutes.
Use the formula to calculate the test statistic,
\(t = \dfrac{(x - \mu)} { \dfrac{s} { \sqrt{n}}}\)
where x is the sample mean, μ is the hypothesized population mean (13 minutes), s is the sample standard deviation, and n is the sample size (6).
Plugging in the numbers, we get:
t = (12.3 - 13) / (2.3 / √6) = -0.72
Using a t-distribution table with 5 degrees of freedom (n - 1), we find that the critical value for a one-tailed test with α = 0.05 is -2.571. Since our calculated t-value (-0.72) is greater than the critical value, we fail to reject the null hypothesis.
Therefore, there is not enough evidence to conclude that the mean time in changing a muffler is less than 13 minutes.
