Alyssa is painting 3 of the walls in her art studio blue. Each of the walls is 8.3 feet tall and 7.5 feet wide. Round the length and width to the nearest whole number (ones). Then estimate the area Alyssa will paint. Write equations to show your work.
Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²

What is the maximum number of hours the repairman estimates for the job?
Answer:
The answer is 5 hours
Step-by-step explanation:
First u add the part and service charge toghther which is 75 and then 225 minus 75 is 150 so u divide 150 and 30 and u get 5 which is your answer.

Identify the system of equations given in the graph below.
Hi there!
[tex]\large\boxed{\left \{ {{y=3x + 1} \atop {y = 3x - 1}} \right}[/tex]
From the graph, we can see that both lines are parallel. We can determine the slope of one line to find the slope of the other.
Use the slope formula to determine the slope of a line. In this case, I am using the blue line as a reference:
[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]
[tex]m = \frac{ 3 - 1 } { 1 - 0 } = 3[/tex]
The slope of both lines is 3.
Let's find the equation of the blue line by finding its y-intercept to solve for the "b" value in the equation y= mx + b:
y-intercept is when x = 0, or at (0, 1). Therefore:
Blue line equation: y = 3x + 1
The red line intersects the y-axis at (0, -1), therefore:
Red line equation: y = 3x - 1
The systems of equations is:
y = 3x + 1
y = 3x - 1
Answer:
y = 2x + 1
y= 2x - 1

Which expressions are equivalent to 5x square root 28x^5+ 8x^3 square root 7x if x>0?
Answer:
1, 2, & 5 in Vertical Order
The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex] is [tex]18x^{3}\sqrt{7x}[/tex].
SimplificationWhat is simplification?In order to simplify an expression, multiple processes must be used to reduce it to a simpler form.
Formula used in simplification:[tex]\sqrt[n]{ab} =\sqrt[n]{a} .\sqrt[n]{b}[/tex]
Simplification of given expression:= [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex]
= [tex]5x\sqrt{4*7x^{5} } + 8x^{3} \sqrt{7x}[/tex]
= [tex]5x\sqrt{2^{2} *7x^{4}x } + 8x^{3} \sqrt{7x}[/tex]
Apply the simplification formula
= [tex]5x\sqrt{2^{2}} \sqrt{x^{4} } \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]
= [tex]5x*2x^{2} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]
Further solve,
= [tex]10x^{3} \sqrt{7x} + 8x^{3} \sqrt{7x}[/tex]
= [tex]18x^{3} \sqrt{7x}[/tex]
The expression equivalent to [tex]5x\sqrt{28x^{5} } + 8x^{3} \sqrt{7x}[/tex] is [tex]18x^{3}\sqrt{7x}[/tex].

The second statement is the
of the first
A. contradiction
B. converse
C. inverse
D. contrapositive
Answer:
The second statement is the contrapositive of the first.
Step-by-step explanation:
We know that x → y is a conditional statement read as 'if x then q'.
The converse EXCHANGES the hypothesis and conclusion such as:
y → x
The 'contrapositive' statement basically NEGATES the converse of the conditional such as:
¬y → ¬x
Coming back towards the question,
Given
x ⇒ y
¬y ⇒ ¬x
Therefore, the second statement is the contrapositive of the first.
Answer:
D. Contrapositive

James is a DJ at local radio station. One day, James offers a cash prize to the first caller who correctly answers a rather difficult trivia question. James’ assistant screens and records all incoming calls, and lets James know when the first call with the correct answer has been received; only then does James air the recording of the caller responding correctly. The probability that a randomly selected caller will correctly answer the trivia question is 0.1.
What is the probability that the third caller is the first to correctly answers the question?
0.01
0.0729
0.081
0.09
0.9
Using the inverse binomial distribution, it is found that there is a 0.081 = 8.1% probability that the third caller is the first to correctly answers the question.
The number of callers that correctly answer the question is a binomial variable, however, we want the probability of the third caller being the first to answer the question correctly, hence it is a negative binomial variable.
Inverse binomial:
It is the number of trials until q successes of a binomial variable, with p probability of success.
The probability mass function is:
[tex]P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
Number of trials until 1 success, hence [tex]q = 1[/tex].0.1 probability of a success on each trial, hence [tex]p = 0.1[/tex].The probability that the third caller is the first to correctly answers the question is P(X = 3), hence:
[tex]P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q[/tex]
[tex]P(X = 3) = C_{3,0}(0.9)^2(0.1)^1 = 0.081[/tex]
0.081 = 8.1% probability that the third caller is the first to correctly answers the question.

Step-by-step explanation:
Natalie and Anjali each improved their yards by planting hostas and shrubs. They bought their supplies from the same store. Natalie spent $86 on 2 hostas and 7 shrubs. Anjali spent $104 on 8 hostas and 4 shrubs. Find the cost of one hosta and the cost of one shrub
Please help it is on solving systems of equation using all methods
Answer: One hosta= $8
One shrub = $10
Step-by-step explanation:
Let the cost of one hostas be h
Let th cost of one shrub be s.
The question can be rewritten into am equation as:
2h + 7s = 86 .......... equation i
8h + 4s = 104 ........ equation ii
Multiply equation i by 8
Multiply equation ii by 2
16h + 56s = 688 ...... equation iii
16h + 8s = 208 ........ equation iv
Subtract equation iv from iii
48s = 480
s = 480/48
s = 10
One shrub cost $10
Put the value of one shrub into equation ii
8h + 4s = 104
8h + 4(10) = 104
8h + 40 = 104
8h = 104 - 40
8h = 64
h = 64/8
h = $8
One hostas cost $8
