Sal is tiling his entryway. The floor plan is drawn on a unit grid. Each unit length represents 1 foot. Tile costs $1.05 per square foot. How much will Sal pay to tile his entryway? Round your answer to the nearest cent.
Sal will pay $77.78 to tile his entryway
SOLUTION:The image of the question is attached below.
Given each unit length = 1 foot
Tile cost per square feet = $1. 65
To find the area, split the floor shape into two shape.
One is trapezoid and the other is parallelogram.
Let's count the grid given.
The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.
The base and height of the parallelogram are 4 ft and 4 ft respectively.
Area of the trapezoid =1/2 ×(sum or parallel sides)× height
=1/2× (7+4)×5
=1/2×11×5
Area of the trapezoid = 27.5 sq.ft
Area of the parallelogram = base × height
= 4 ft × 4 ft
Area of the parallelogram = 16 sq. ft
Total area = 27.5 sq. ft + 16 sq. ft
= 43.5 sq. ft
Cost of area per sq. ft = $1.65
Cost of area 43.5 sq. ft = 43. 5 × 1.65
= $71.775
= $71.78
Hence Sal will pay $71.78 to tile his entryway.

eric invested 5000 dollars in the stock market. The value of his stock increased by 13%. a) what is the amount earned from this investment?
b) what is the new value of the stock?
Answer:
[tex]Earnings = 650[/tex]
[tex]New\ Value = 5650[/tex]
Step-by-step explanation:
Given
[tex]Amount = 5000[/tex]
[tex]Rate = 13\%[/tex]
Solving (a): The earnings.
This is calculated as:
[tex]Earnings = Amount * Rate[/tex]
[tex]Earnings = 5000 * 13\%[/tex]
[tex]Earnings = 650[/tex]
Solving (b): New Value
This is calculated as:
So, we have:
[tex]New\ Value = Amount + Earnings[/tex]
[tex]New\ Value = 5000 + 650[/tex]
[tex]New\ Value = 5650[/tex]

Answer:
[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex] -- Perfect square trinomial
[tex](n + \frac{1}{3})^2 = \frac{1}{9}[/tex] ---Binomial squared
Step-by-step explanation:
Given
[tex]n^2 + \frac{2n}{3}[/tex]
Solving (a): Perfect square trinomial
We have:
[tex]n^2 + \frac{2n}{3}[/tex]
Express as an equation
[tex]n^2 + \frac{2n}{3} =[/tex]
Start----------------------------
Take coefficient of n i.e. (2/3)
Half it: i.e. (1/3)
Square it: (1/63^2
Add to both sides of the equation
---------------------------End
So, we have:
[tex]n^2 + \frac{2n}{3} + (\frac{1}{3})^2 = (\frac{1}{3})^2[/tex]
Remove brackets
[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]
Solving (b): Binomial Squared
[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]
Expand
[tex]n^2 + \frac{n}{3}+ \frac{n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]
Factorize:
[tex]n(n + \frac{1}{3})+ \frac{1}{3}(n + \frac{1}{3}) = \frac{1}{9}[/tex]
Factor out n + 1/3
[tex](n + \frac{1}{3})(n + \frac{1}{3}) = \frac{1}{9}[/tex]
Express as square
[tex](n + \frac{1}{3})^2 = \frac{1}{9}[/tex]

One satellite is scheduled to be launched from Cape Canaveral in Florida, and another launching is scheduled for Vandenberg Air Force Base in California. Let A denote the event that the Vandenberg launch goes off on schedule, and let B represent the event that the Cape Canaveral launch goes off on schedule. If A and B are independent events with P(A) > P(B), P(A ∪B) = 0.626, and P(A ∩B) =0.144.
Required:
Determine the values of P(A) and P(B).
Answer:
[tex]P(A) = 0.45[/tex]
[tex]P(B) = 0.32[/tex]
Step-by-step explanation:
Given
[tex]P(A) > P(B)[/tex]
[tex]P(A\ u\ B) = 0.626[/tex]
[tex]P(A\ n\ B) = 0.144[/tex]
Required
Find P(A) and P(B)
We have that:
[tex]P(A\ u\ B) = P(A) + P(B) - P(A\ n\ B)[/tex] --- (1)
and
[tex]P(A\ n\ B) = P(A) * P(B)[/tex] --- (2)
The equations become:
[tex]P(A\ u\ B) = P(A) + P(B) - P(A\ n\ B)[/tex] --- (1)
[tex]0.626 = P(A) + P(B) - 0.144[/tex]
Collect like terms
[tex]P(A) + P(B) = 0.626 + 0.144[/tex]
[tex]P(A) + P(B) = 0.770[/tex]
Make P(A) the subject
[tex]P(A) = 0.770 - P(B)[/tex]
[tex]P(A\ n\ B) = P(A) * P(B)[/tex] --- (2)
[tex]0.144 = P(A) * P(B)[/tex]
[tex]P(A) * P(B) = 0.144[/tex]
Substitute: [tex]P(A) = 0.770 - P(B)[/tex]
[tex][0.770 - P(B)] * P(B) = 0.144[/tex]
Open bracket
[tex]0.770P(B) - P(B)^2 = 0.144[/tex]
Represent P(B) with x
[tex]0.770x - x^2 = 0.144[/tex]
Rewrite as:
[tex]x^2 - 0.770x + 0.144 = 0[/tex]
Expand
[tex]x^2 - 0.45x - 0.32x + 0.144 = 0[/tex]
Factorize:
[tex]x[x - 0.45] - 0.32[x - 0.45]= 0[/tex]
Factor out x - 0.45
[tex][x - 0.32][x - 0.45]= 0[/tex]
Split
[tex]x - 0.32= 0 \ or\ x - 0.45= 0[/tex]
Solve for x
[tex]x = 0.32\ or\ x = 0.45[/tex]
Recall that:
[tex]P(B) = x[/tex]
So, we have:
[tex]P(B) = 0.32 \ or \ P(B) = 0.45[/tex]
Recall that:
[tex]P(A) = 0.770 - P(B)[/tex]
So, we have:
[tex]P(A) = 0.770 - 0.32 \ or\ P(A) =0.770 - 0.45[/tex]
[tex]P(A) = 0.45 \ or\ P(A) =0.32[/tex]
Since:
[tex]P(A) > P(B)[/tex]
Then:
[tex]P(A) = 0.45[/tex]
[tex]P(B) = 0.32[/tex]

Answer:
1.6
Step-by-step explanation:
So, first, write down the number of jokers in each deck of cards.
That would be: 0, 1, 2, 2, 3
Then, add up all those numbers.
0+1+2+2+3=8
Now, divide that sum by the number of decks or cards shown in the data set, which would be 5.
8/5=1.6
So, the mean of the data in the dot plot shown is 1.6.

9514 1404 393
Answer:
d. √74 units
Step-by-step explanation:
The distance formula is useful for finding the length of a line segment.
d = √((x2 -x1)^2 +(y2 -y1)^2)
Filling in the point coordinates L(-5, -3) and M(0, 4), we find the length of LM to be ...
LM = √((0-(-5))^2 +(4 -(-3))^2) = √(25 +49)
LM = √74 . . . units

2.5x+12=48 can y’all help
Answer: x=14.4
Step-by-step explanation:2.5x=48-12
2.5x=36
x=14.4
Answer:
x = 14.4
Step-by-step explanation:
2.5x + 12 = 48
2.5x + 12 - 12 = 48 - 12
2.5x = 36
2.5x ÷ 2.5 = 36 ÷ 2.5
x = 14.4
in angle RST, the measure of
Answer:
Angle RST is a straight angle, or 180°.
Step-by-step explanation:
Subsequently, question is, what is RST measured in? Triangle RST is isosceles means that two of its angles are equal. (1) The measure of angle T is 100 degrees --> since no other angle can be equal to 100 degrees (because in this case the sum of the angles will be more than 180 degrees) then the other two angles, R and S, are equal: R=(180-100)/2=40.
Likewise, people ask, what is the measure of angle rst 94?
Then the measure of arc RST is 94° +96° = 190°.
What is the measure of arc rst?
— RT is a diameter, so RST is a semicircle, and m RST = 180°. The measure of a minor arc is the measure of its central angle. The expression m AB is read as “the measure of arc AB.” The measure of the entire circle is 360°.

1636.4
Step-by-step explanation:
To find this you need to figure out what the probability of you needing it is. I believe that you then need to see how much you will pay with that. ex:1050 with only 32% chance that you will need it. So 336. 225 but only 45 %, so 121.25.
1,580 guarantied. 24. 32.4. Add all these together you get 1636.4.
