Answer:
The numbers described here are 39 and 11.
Step-by-step explanation:
Let's call the numbers a and b, a being the larger. We're told two things:
The larger of the two numbers is 17 more than twice the smaller.
Which we can express as:
a = 2b + 17
When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6
And that can be expressed as:
a = 3b + 6
We can now take those two expressions and, noting that they both define a, we can say that they are equivalent, and solve for b:
2b + 17 = 3b + 6
3b - 2b = 17 - 6
b = 11
With b found, we can now take either of the first expressions, and solve for a:
a = 2b + 17
a = 2(11) + 17
a = 22 + 17
a = 39
Now we can check whether that is correct by plugging it into the other expression and seeing if b still comes to 11:
a = 3b + 6
39 = 3b + 6
3b = 33
b = 11
So we know that the answer is correct.

Mr. Brettler is hanging up a 5-foot tall rectangular welcome sign in the gym. He has drawn a sketch on a coordinate grid.
He has the lower vertices of the sign at (9,-3) and (-6, -3). Where would the upper vertices be on the grid?
Answer:
(9,2) and (-6,2).
Step-by-step explanation:
Rectangular Coordinates
The lower vertices of a rectangular welcome sign in Mr. Brettler's gym are (9,-3) and (-6,-3).
Note these two vertices are 3 units below the x-axis. We know the sign is 5-foot tall, so the y-coordinates of the two upper vertices should be -3+5=2.
The upper vertices of the sign on the grid are (9,2) and (-6,2).
A bag contains counters that are red, black , or green . 1/3 of the counters are red 1/6 of the counters are black There are 15 green counters in the bag. How many black counters are in the bag ?
i’ll give brainliest;)
Answer:
Number of black counters = 5
Step-by-step explanation:
Let,
x be the total number of counters
Number of red counters = [tex]\frac{1}{3}x[/tex]
Number of black counters = [tex]\frac{1}{6}x[/tex]
Number of green counters = 15
Now,
Red counters + Black counters + Green counters = Total counters
[tex]\frac{1}{3}x+\frac{1}{6}x+15=x\\\\\frac{2x+x+90}{6}=x\\\\3x+90 = 6x\\90 = 6x-3x \\90 = 3x\\3x = 90[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{90}{3}\\x=30[/tex]
Number of black counters = [tex]\frac{1}{6}*30[/tex] = 5
Hence,
Number of black counters = 5

A student has a container with a volume of 2.5 liters. She estimates the volume to be 2.4 liters. By
what percent is the student's estimate off?
Answer:
She is wrong. Since is .5, you round up to the nearest tenth. So it is 2.0
Step-by-step explanation:
If student has a container with a volume of 2.5 liters. She estimates the volume to be 2.4 liters. Then by 4% the student's estimate off
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The container of a student has a volume of 2.5 liters.
She estimates the volume to be 2.4 liters
We need to find the percent of student's estimate off.
To find this we have to find the difference of 2.5 and 2.4
2.5-2.4=0.1
Now divide zero point one divided by two point five
0.1/2.5
0.04
Multiply with hundred
0.04×100=4%
Hence 4 % is the students estimate off

Consider the Function
Which function could be the inverse of function f?
Answer:
Explanation below, despite missing details in question.
Step-by-step explanation:
The function isn't given but we know it's labelled "f".
The inverse of a function (likewise the inverse of any other quantity) is simply the function turned up-side-down.
To invert a function, you switch the places of both numerator and denominator. Example:
f = [tex]\frac{x}{y}[/tex]
the inverse of the function above is y/x
If the function is not in fraction form or doesn't have a visible denominator, take the denominator to be 1.
The denominator of every number or function is 1, so you'll be correct doing this.
If f = 2n +5 then the inverse of f will be [tex]\frac{1}{2n + 5}[/tex]
NOTE: Inverse of f ≡ 1/f ≡ [tex]f^{-1}[/tex]

Answer:
The expression can be rewritten by combining like terms such as:
[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)=0.25\left(-8y-12\right)[/tex]
Step-by-step explanation:
Like term:
We know that like terms are those terms with:
same variablessame exponentsFor example,
2x and 4x are the like terms. Both have the same variables and the same power of the variable.
Similarly, 2x³ and 4x³ are like terms. Both have the same variables and the same exponents of the variables.
Please note that the like terms may have different coefficients of the variables.
NOW, REWRITING THE EXPRESSION BY COMBINING LIKE TERMS
Given the expression
[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)[/tex]
Here in the parentheses:
2/3y, 1/3y, and 9y are like terms.5 and 7 are like terms.as
2/3y + 1/3y - 9y = y - 9y = -8y-5-7 = -12Combining like terms in the parentheses
[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)=0.25\left(-8y-12\right)[/tex]
Therefore, the expression can be rewritten by combining like terms such as:
[tex]0.25\:\left(\frac{2}{3}y\:-\:5\:+\:\frac{1}{3}y\:-\:7\:-\:9y\right)=0.25\left(-8y-12\right)[/tex]
A research study showed that a sample of 25 dosages from a medicine dispensing machine averaged 24.1 mg of a certain drug. The sample standard deviation was 1.8 mg. a) Form a 99% confidence interval of the population average of drug dosage dispensed. b) Explain what this interval means to someone unfamiliar with this research.
Answer:
a) The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.
b) It means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
a)
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.797
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.797\frac{1.8}{\sqrt{25}} = 1[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 24.1 - 1 = 23.1 mg
The upper end of the interval is the sample mean added to M. So it is 24.1 + 1 = 25.1 mg
The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.
b)
The interval means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.

How to calculate the surface area of a composite figure?Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
We are given that;
Angle = 145°
Now,
The area of a sector of a circle is given by the formula A = (θ/360)πr2, where θ is the central angle in degrees and r is the radius of the circle. In this case, θ = 145° and r = 7 in.
Plugging these values into the formula, we get: A = (145/360)π(7)^2. Simplifying, we get: A = 0.4028π(49). Using a calculator, we get: A ≈ 34.6 in2.
Therefore, by the area the answer will be 34.6 in2.
