If Eof= 26 and FOG= 38, then what is the measure of BOG? The diagram is not to scale.
If EOF = 26 and FOG= 38, then the measure of BOG would be 64 degrees.
What is a measure of angle?
An angle is measured in degrees, thus the term "degree measure." Because one complete revolution equals 360 degrees, it is divided into 360 parts. Each stage of the revolution represents a degree.
The given data:
A measure of EOF = 26 and a measure of FOG = 38.
Then we can say that OF is an angle bisector of angle EOG.
Then the measure of BOG = EOF + FOG
= 26 + 38
= 64 degrees.
Hence, If EOF = 26 and FOG= 38, then the measure of BOG would be 64 degrees.

pls answer this one as quick as possible.
Value of [tex]a^5-\frac{1}{a^5}[/tex] is 31.97.
What do you mean by algebraic expression?
In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.
There are 3 main types of algebraic expressions which include:
Monomial Expression
Binomial Expression
Polynomial Expression
An algebraic expression which is having only one term is known as a monomial.
Given expression:
a + 4/a = 4
We need to simplify the above expression and will find the value of a.
[tex]a+\frac{4}{a}=4[/tex]
⇒ [tex]\frac{a^2+4}{a}=4[/tex]
⇒ [tex]a^{2}+4=4a[/tex]
⇒ [tex]a^2-4a+4=0[/tex]
⇒ [tex]a^2-2a-2a+4=0[/tex]
⇒ a(a-2) -2(a-2) = 0
⇒ (a-2)(a-2) = 0
⇒ a = 2
Now, substitute this value of a in expression , [tex]a^5-\frac{1}{a^5}[/tex]
[tex]2^5-\frac{1}{2^5}[/tex]
= 32 - 1/32
= [tex]\frac{1024-1}{32} =1023/32 = 31.97[/tex]

-x/y is equivalent to x/-y according to the division rule a/b*d/c=a/b*c/d.
Describe division.In division, a number is divided, which is an easy operation. In mathematics, division is the division of a sum into equal parts. A group of 20 people, for instance, could be divided into four groups of 5, five groups of 4, and so on. Division's opposite is multiplication. If 3 groups of 4 add up to 12, then 4 are in each group when 12 is divided into 3 equal groups.

a bank auditor claims that credit card balances are normally distributed, with a mean of $2870 and a standard deviation of $900. a) what is the probability that a randomly selected credit card holder has a credit card balance less than $2500? b) you randomly select 25 credit card holders. what is the probability that their mean credit card balance is less than $2500? c) compare the probabilities from a) and b).
(a) -0.255 is the probability that a randomly selected credit card holder has a credit card balance less than $2500. (b) You randomly select 25 credit card holders. 0.0228 is the probability that their mean credit card balance is less than $2500.
Let us pull out the critical elements
Population: Normally distributed with mean of 2870
population standard deviation = 900 standard deviation of the sample mean (standard error) is 900 / √25. or 180
As population sigma is known, we do not have apply any corrections
P(xbar < $2500) = ?
Since μ and σ are known (population mean and standard deviation) we can use a simple Z test.
Ztest = (2500-2870 )/ 180 or -370/180 = -2.055
As this is very close to -2 one can use the rule of thumb for probability within ± 2 sigma being 95.44% to get a close estimate. If the area between -2 and 2 sigma = .9544 then the area outside = .0456. Half of this (the amount under the curve LESS THAN -2) would be .0228
Using a calculator or computer for an exact answer we find (using a TI-83/86):

What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
The saving of Sarah = $50,000
The interest on $25,000 Sarah withdrew at the rate of 4% = $1000
The interest on $30,000 Sarah borrowed at the rate of 4% = %1200
The amount paid for ingredients = $27,000
Total investment = 27,000+30,000+ 1000+1200 = $59,200
Revenue of Sarah = $70,000
Accounting profit of Sarah = $70,000 - $59,200 = $10,800
Economic profit of Sarah = $70,000 - ($59,200+$25,000)

The number of students in the class after the changes here are 35.
What are ratios?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)
The question tells us that 7 more juniors have joined this class, while 2 seniors have dropped the class. Then the ratio would be 5 : 2 from the question.
This would give us the ratios as
[tex]\frac{3x+7}{2x-2} = \frac{5}{2}[/tex]From here we would have to cross multiply
2(3x + 7) = 5(2x - 2)

The number of books each boy had based on the 3:1 ratio of the books remaining is 34 books
What is a ratio?A ratio is a quantitative expression of the relationship between two values that indicates the relative proportion of each amount.
The initial number of books Ben had = The initial number of books Charlie has
The number of books Ben gave away = 16 books
The number of books Charlie gave away = 28 books
The ratio of the number of books Ben and Charlie had left is 3:1
Let x represent the number of books each of them initially have. Representing the numbers as a ratio gives;
The number of books Ben had left = x - 16
The number of books Charlie had left = x - 28
[tex]\dfrac{x - 16}{(x - 16) + (x - 28)} = \dfrac{3}{3+1}[/tex]

shopper needs 48 hot dogs. The store sells identical hot dogs in 2 differently sized packages. They sell a six-pack of hot dogs for $2.10, and an eight-pack of hot dogs for $3.12.
The pack of hot dogs that the shopper should buy that would be cheaper is six - pack of hot dogs
How to find the pack to be bought?If the shopper decided to buy the six-pack of hot dogs for $2.10, their total cost to be able to get 48 hot dogs would be:
= Cost per six pack of hot dogs x ( Number of hot dogs needed / Number of hot dogs in pack)
