Check all the equations that apply to meet the Segment Addition Postulate in segment OQ. OP = 6x + 5, PQ = 4x and OQ = 45.
Answer:
[tex]6x + 5 + 4x = 45[/tex]
[tex]10x = 40[/tex]
Step-by-step explanation:
Given
[tex]OP = 6x + 5[/tex]
[tex]PQ = 4x[/tex]
[tex]OQ = 45[/tex]
The given parameters show that P is a point between O and Q.
So:
[tex]OQ = OP + PQ[/tex]
Substitute values for OP, PQ and OQ
[tex]45 = 6x + 5 + 4x[/tex]
[tex]6x + 5 + 4x = 45[/tex] --- This is an equation

1. Approximately what was the total expenditure on entertainment if separated amount of $11,406.30, $1,669.72, $2,506.81 and $1,930.20 were spent?
Answer:
The approximate expenditure spent on entertainment is $17,513
Step-by-step explanation:
To get the total entertainment expenditure, we simply add up all these values
We have;
11,406.30 + 1669.72 + 2506.81 + 1930.20 = 17,513.03
The total expenditure spent on entertainment is approximately $17,513
Beth is making a rope ladder each step of the ladder is 2 1/3 feet wide width as a rope that is 21 feet long how many steps can she make from the rope
Answer:
Answer: She can make 9 steps from the rope.
Step-by-step explanation:
Given : The width of each step of the ladder = 2\dfrac{1}{3}\text{ feet}2

feet = \dfrac{2(3)+1}{3}=\dfrac{7}{3}\text{ feet}

The length of the rope = 21 feet
Then , the number of required steps = ( length of the rope ) ÷ (width of each step of the ladder)
=21\div\dfrac{7}{3}=21÷

What is the value of y?
Answer:
A. 13
Step-by-step explanation:
[tex] (6y - 14) + 90 + (2y) = 180 [/tex] (angles on a straight line)
Solve for y
[tex] 6y - 14 + 90 + 2y = 180 [/tex]
Collect like terms
[tex] 6y + 2y - 14 + 90 = 180 [/tex]
[tex] 8y + 76 = 180 [/tex]
Subtract 76 to both sides
[tex] 8y + 76 - 76 = 180 - 76 [/tex]
[tex] 8y = 104 [/tex]
Divide both sides by 8
[tex] \frac{8y}{8} = \frac{104}{8} [/tex]
[tex] y = 13 [/tex]

Mr. Hickman's cherry tree grew 12 inches in of a year. At that rate,
4
how much would it grow in 1 year?
Answer:
At the given rate, Mr. Hickman's cherry tree would grow 16 inches in 1 year.
Step-by-step explanation:
I assume the actual question is:
"Mr. Hickman` s cherry tree grew 12 inches in 3/4 of a year. How much would it grow in one year ?"
As stated,
In 3/4 of a year, Mr. Hickman's cherry tree grew = 12 inches
Therefore,
In 1 year, Mr. Hickman's cherry tree would grow = [tex]\frac{1}{\frac{3}{4} }*12[/tex] inches
= 4/3 * 12 inches
= 16 inches
Hence, at the given rate, Mr. Hickman's cherry tree would grow 16 inches in 1 year.
The random variable X is known to be uniformly distributed between 2 and 12. Compute E(X), the expected value of the distribution.
Answer:
The expected value of the distribution is 7.
Step-by-step explanation:
The random variable X is known to be uniformly distributed between 2 and 12.
The probability density function of X is:
[tex]f_{X}(x)=\frac{1}{b-a};\ a<X<b[/tex]
Here a = 2 and b and 12.
Compute the expected value of the distribution as follows:
[tex]E(X)=\frac{a+b}{2}[/tex]
[tex]=\frac{2+12}{2}\\\\=\frac{14}{2}\\\\=7[/tex]
Thus, the expected value of the distribution is 7.

How do I find y to solve for the vertex? (Transformations, Quadratic functions)
I know how to solve for the x but I'm confused on solving for the Y. Thank you!
Answer:
the other answer is zero.
Step-by-step explanation:
Step 1: Use the vertex form, [tex]y=a(x-h)^2+k[/tex], to determine the values of a, h, and k. The "k" value is always the "y" value in a ordered pair. Since there is no "k" value, the "k" value will just be zero. In turn, since the "k" value is zero... so will the "y" value be zero.

Choose all the expressions that are equal to 0.7 × 0.41.
A. 7100×41100
B. 710×41100
C. 7100×4110
D. 710×4110
E. 70100×41100
Answer:
None of the expressions is equal to 0.7 x 0.41.
Step-by-step explanation:
Given that 0.7 x 0.41 is equal to 0.287, to determine which options are equal to said operation, the calculations set out for each of them must be performed:
A. 7,100 × 41100 = 291,810,000
B. 710 × 41100 = 29,181,000
C. 7100 × 4110 = 29,181,000
D. 710 × 4110 = 2,918,100
E. 70100 × 41100 = 2,918,100,000
Therefore, looking at all the results produced by the predisposed calculations, it is evident that none of the expressions is equal to 0.7 x 0.41.
There is no expression equivalent to the given expression and this can be determined by using the arithmetic operations.
Given :
Expression -- 0.7 × 0.41
The arithmetic operations can be used in order to evaluate the given expression.
[tex]0.7\times 0.41 = 0.287[/tex]
Now, check all the options in order to determine the correct option.
A) 7100×41100
Evaluate the above expression by using the arithmetic operations.
[tex]7100\times 41100 = 291810000[/tex]
Therefore, this option is incorrect.
B) 710×41100
Evaluate the above expression by using the arithmetic operations.
[tex]710\times 41100 = 29181000[/tex]
Therefore, this option is incorrect.
C) 7100×4110
Evaluate the above expression by using the arithmetic operations.
[tex]7100\times 4110 = 29181000[/tex]
Therefore, this option is incorrect.
D) 710×4110
Evaluate the above expression by using the arithmetic operations.
[tex]710\times 4110 = 2918100[/tex]
Therefore, this option is incorrect.
E) 70100×41100
Evaluate the above expression by using the arithmetic operations.
[tex]70100\times 41100 =2881110000[/tex]
Therefore, this option is incorrect.

Find the 89th term of the arithmetic sequence
-13, -8, -3
Answer:
427
Step-by-step explanation:
first you have to find the difference between -13 and -8 so we do -13 minus -8 which gives us -13 +8 which is -5. so -13+5=-8 then we try plugging in 5 to the next two numbers -8+5=-3 so the pattern is +5 so now we can do 5*88=440 so now we do -13+440=427

Hermina cut a ft by ft piece of plywood down the diagonal.
A rectangle is 4 feet wide and 8 feet long. A diagonal cut is shown with a line labeled c. The cut divides the rectangle in half and creates two right triangles. The hypotenuse of each right triangle is the line labeled c.
What is the length c of the cut, in feet?
Answer:
[tex]\sqrt{80} = c[/tex] is the answer.
Step-by-step explanation:
We can solve this using the Pythagorean theorem.
We know we can use the pythagorean theorem because it has a 90 degree angle.
[tex]a^{2}+ b^{2}= c^{2}[/tex]
We are given the sides 4 and 8.

A newspaper ran a story concerning the increasing prices of mobile phones. The story stated that mobile phone prices dropped a few years ago, but now are beginning to increase in price because of added features.
• According to the story, the average price of all mobile phones a few years ago was £215.
• A large random sample of mobile phones (n = 200) was taken, and their prices recorded.
• We wish to use a hypothesis test to determine if the average price of all mobile phones is now greater than £215.
Required: Define the hypotheses, and with reference to the applicable random variable distribution, find the rejection region appropriate for this test if we are using the significance level α = 0.05.
Answer:
H0 : μ = 215
H1 : μ > 215
Rejection region :
Zstatistic > Z0.05
Step-by-step explanation:
Given that:
Average price of all mobile phones was £215
Sample size = 200
Significance level (α) = 0.05
To determine if the average price of all mobile phones is now greater than £215
The Null hypothesis (H0) :
H0 : μ = 215
Alternative hypothesis (H1) :
H1 : μ > 215
The rejection region :
|Zstatistic > Zα|
α = 0.05 ; Z0.05
Rejection region :
Zstatistic > Z0.05
All swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45. Find the discount.
The discount is $18 if the all swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
All swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45.
The regular price = $45
The discount is worth = 40% of 45
= (40×45)/100
= $18
Thus, the discount is $18 if the all swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45.
