Answer:
(B)
b + t = 15
2b + 3t = 45
Step-by-step explanation:
Bicycles and tricycles are represented by the letters b and t respectively.
total no of bicycles and tricycles = 15
So,
b + t = 15
Each bicycle has 2 wheels and each tricycle has three wheels.
So,
No of wheels in b bicycles = 2b
No of wheels in t tricycles = 3t
Total no of wheels = 45
So,
2b + 3t = 45

Select all that apply.
A. m angle Q = 63
B. m angle R = 81
D. m angle P = 81
C. RP = 4.5
Answer:
C. RP = 4.5
Step-by-step explanation:
You want to know what condition is sufficient to show ∆ABC ~ ∆QPR, given three sides and 2 angles in ∆ABC, and 2 sides in ∆QPR.
SimilaritySimilarity can be shown if all three sides are proportional, or if two angles are congruent.
The offered answer choices only list one angle, so none of those will work. The answer choice that makes the third side of ∆QPR be in the same proportion as the corresponding side of ∆ABC is the condition of interest.
C. RP = 4.5
__
Additional comment
The side ratios in the two triangles are ...
AB : BC : CA = 10 : 9 : 6
QP : PR : RQ = 5 : PR : 3
For these ratios to be the same, PR must be half of BC, just as the other segments in ∆QPR are half their counterparts in ∆ABC.

The proportion is solved and the variables are a/b = c/d
Given data ,
Let the proportion be represented as A
Now , the value of A is
a / b = c / d
On simplifying the equation , we get
( a + b ) / b = ( c + d ) / d
On dividing the numerator of the fraction by the denominator , we get
( a / b ) + ( b / b ) = ( c / d ) + ( d / d )
On further simplification , we get
( a / b ) + 1 = ( c / d ) + 1
Subtracting 1 on both sides , we get
( a / b ) = ( c / d )
Hence , the proportion is ( a / b ) = ( c / d )

Explain about the measuring units:Numbers are traits or features that we are attempting to gauge, such as an object's length. We represent measurements of quantities using units of measure. In science, we would measure length in metres.
A unit is basically just a specific amount of a quantity that is used as a benchmark when measuring that quantity. To put it another way, the individuals who use a given unit of measurement decide on and approve it. When describing a specific measurement, the base unit of measure may be either too big or too little.Given that:
weight of bunch of grapes = 3 pounds 6 ounces.
We know that,
1 pound = 16 ounce
3 pounds = 16*3 = 48 ounce
weight of bunch of grapes = 48 ounce + 6 ounces.
weight of bunch of grapes = 54 ounces.
Thus, the weight of bunch of grapes is found as: 54 ounces.

What is the meaning of "the cancellation laws"?
Each step of this theorem is proved below.
Given that,
S is finite,
Now enumerate all of its elements as x₁, x₂,..., x\(_{n}\).
According to the cancellation rule,
This product is independent of the order of the factors.
As a result, we can define the identity element e as this product.
It is simple to demonstrate that e meets the criteria of an identity element.
Now, let's show that every element of S has an inverse.
Let a be any element of S. Consider the set {a, a, a, ...}.
Since S is finite,
There exist positive integers m and n such that
am = an for some m > n.
By the cancellation law,
We can cancel a power of a from both sides to get a\({(m-n)}\) = e.
This means that a has an inverse, and we can conclude that S is a group.
Consider the set of all positive integers under addition, except 1, as an example of an infinite semigroup in which the cancellation laws hold but which is not a group.
This set clearly meets the cancellation laws, but it does not have an inverse for every element, because the inverse of 2, for example, is not an integer.
As a result, this is not a group.

A company had beginning inventory of 200 units costing $5.00 each. During the year they made the following purchases: April 20, 300 units at $6.00 each; June 14, 250 units at $7.00 each; August 12, 200 units at $8.00 each; and November 15, 50 units at $9.00 each. There were 260 units remaining in inventory at the end of the year. What was the value of the ending inventory, assuming FIFO? $2,120.00 $2,210.00 $1,630.00 $1,360.00
Answer:
$2120 (closing inventory)
Step-by-step explanation:
FIFO is first in first out method of stock keeping. So basically here you have the closing inventory of 260 units. So you can take:
50 * 9 = 450
200 * 8 = 1600 (since its FIFO so you sell that stock first which you purchased first after which you are
10 * 7 = 70 left with this - adds up to 260 units )
50 + 200 + 10 = 260 units
$450 + $1600 + $70 = $2120 (closing inventory)
Answer:

Answer:
Yes
Step-by-step explanation:
To find this out. If you divide the denominators by each other, they would need to be the same value as if you divide the numerators by each other
\(45 \div 9 = 5\)
^ 45 and 9 were the denominators, we divide and get 5
Now for the numerators
\(10 \div 2 = 5\)
^ 10 and 2 we're the numerators, dividing also gave 5
Answer:
yes.
Step-by-step explanation:
let us check. to be a proportion they must be equivalent
however, what do we multiply to get there? let us check..
\(\frac{2x}{9x} =\frac{10}{45}\)
cross multiply...
2x * 45 = 9x * 10

The city of Gainesville is trying to determine the average price for a gallon of gas. They randomly sampled 28 gas stations and found the sample mean to be $2.58 with a standard deviation of $0.09. Assume that all of the assumptions are met. Calculate a 95% confidence interval for the population mean gas price in Gainesville.
Answer:
The 95% confidence interval for the population mean gas price in Gainesville is between $2.54 and $2.62.
Step-by-step explanation:
We have the standard deviation of the sample, so we use the t-distribution to solve this question.
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 = 28 - 1 = 27
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 27 degrees of freedom(y-axis) and a confidence level of \(1 - \frac{1 - 0.95}{2} = 0.975\). So we have T = 2.0.52
The margin of error is:
\(M = T\frac{s}{\sqrt{n}} = 2.052\frac{0.09}{\sqrt{27}} = 0.04\)
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 $2.58 - $0.04 = $2.54
The upper end of the interval is the sample mean added to M. So it is $2.58 + $0.04 = $2.62.
The 95% confidence interval for the population mean gas price in Gainesville is between $2.54 and $2.62.
A linear transformation T : Rn → Rm is completely determined by its effect on columns of the n × n identity matrix
It is true that a linear transformation T : Rn → Rm is completely determined by its effect on columns of the n × n identity matrix.
What is a linear transformation?
A linear transformation is a function from one vector space to another that takes into account the underlying (linear) structure of each vector space. Another term for a linear transformation is a linear operator, sometimes known as a map.
The basis vectors in Rn are the columns on the identity matrix.
Since T is a linear transformation and any vector can be expressed as a linear combination of these, if we know where these columns go, we know everything.

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.
Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.
This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.
He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.
Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.
Thus, looking at the provided options, option B ($850.00) would be the correct answer.
