Step-by-step explanation:
Patio is in the shape of a parallelogram.
Formula for the area of a parallelogram is,
Area = [tex](\text{Base})(\text{Height})[/tex]
= 16.2 × 12
= 194.4 square feet
∵ 50 square feet area is covered by 1 bag of concrete mix.
∴ 1 square feet area will be covered by [tex]\frac{1}{50}[/tex] bag of concrete mix
∴ 194.4 square feet patio will require the concrete mix = [tex]\frac{194.4}{50}[/tex]
= 3.888
≈ 4 bags
Therefore, 4 bags of concrete mix will be required by Dave to add a new patio.

Répondre:
AI = 32,36 m
IE = 30,78 m
Explication étape par étape:
Utilisation de Pythagore:
Cosθ = adjacent / hypoténus
AI = hypoténus
θ = 72 °
Adjacent = 10 m
Cos 72 = 10 / AI
0,3090169 = 10 / AI
AI = 10 / 0,3090169
AI = 32,36 m
De la trigonométrie;
IE = opposé
Adjacent = 10m
Tanθ = opposé / adjacent
Tan 72 = IE / 10
IE = Tan 72 * 10
IE = 3,0776835 * 10
IE = 30,78 m

N artist makes three types of ceramic statues (large, medium, and small) at a monthly cost of $760 for 210 statues. The manufacturing costs for the three types are $5, $4, and $3. If the statues sell for $26, $18, and $15, respectively, how many of each type should be made to produce $3,640 in monthly revenue?
Answer:
20, 90 and 100
Step-by-step explanation:
Total number of statues = 210
Assuming that a large statue = x, medium statue = y and a small statue = z
Then, x + y + z = 210........i
Also, we're told that the monthly cost is $760, so
5x + 4y + 3z = 760.........ii
Cost of selling is $3640, so then
26x + 18y + 15z = 3640.........iii
Solving i and ii simultaneously, we have
5x + 5y + 5z = 1050
5x + 4y + 3z = 760
Subtracting, we have
y + 2z = 290.........iv
Again, solving ii and iii simultaneously, we have
130x + 104y + 78z = 19760
130x + 90y + 75z = 18200
On subtracting, we have
14y + 3z = 1560.........v
And finally, solving iv and v simultaneously, we also have
14y + 28z = 4060
14y + 3z = 1560
On subtracting,
25z = 2500
z = 2500 / 25
z = 100
Substituting for z = 100 in iv, we have
y + 2(100) = 290
y + 200 = 290
y = 290 - 200
y = 90
Substituting for y = 90, and z = 100 in i
x + 90 + 100 = 210
x + 190 = 210
x = 210 - 190
x = 20
Therefore, large statues has to be 20, medium statues has to be 90, and small statues has to be 100

You bought an item for $25 on Ebay and plan on marking it up 65%. What price will you sell your item for to the nearest dollar?
Answer:
$41.25
Step-by-step explanation:
The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.
Let's make an equation.
65/100 • 25 = x
Multiply.
x = 16.25
Now we know how much you want to mark it up by.
Add this to your base of $25.
25 + 16.25
= 41.25
You want to sell it for $41.25.
Hope this helps!
A mortgage has an initial balance of $150,000 and is charged 5% yearly interest applied monthly. If a person makes a payment of $1000 each month, which of the following is closest to the mortgage balance after 3 months of payments?
(1) $145,165
(2)$147,520
(3)$148,160
(4)$148,870
A mortgage loan is termed as a loan that is used to purchase or maintain a home, land or other pieces of real estate.
The borrower agrees to repay the amount of loan to the lender over a period of time, usually in a series of regular installments divided into principal and interest. The property is used as security for the loan.
Calculation of the amount of mortgage is as follows:
[tex]\text{Interest}= \text{Mortgage amount} \times\frac{0.05}{12}\times3[/tex] = 1875
[tex]\text{Principal Pay }= 1000 \times3[/tex] = 3000
Total amount paid = Interest + principal pay = 1875 + 3000 = 4875
Initial balance = 150000
The remaining balance for the mortgage amount = initial balance - the total amount paid.
Amount of mortgage = $ 145125.
Therefore the closest to the mortgage balance after 3 months of payments is
(1) $145,165.

What are supplementary angles?Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
Here, we're specified that:
m∠PRM = measure of angle PRM = (7x -11)°m∠NRP = measure of angle NRP= (4x -7)°They are adjacent and line segments MR and RN are forming a straight line MN, so these angles are supplementary. That means:
(7x -11)° + (4x -7)° = 180°
Opening the brackets, and solving in terms of magnitude, we get:
[tex]7x - 11 + 4x -7 = 180\\11x - 18 = 180\\11x = 180+18 \\\\x = \dfrac{198}{11} = 18[/tex]
Thus, the value of x which is included in terms of both the angles ∠PRM and ∠NRP is given by: Option D: x = 18

You bought 7 raffle tickets. A total of 1302 raffle tickets were sold. If every raffle ticket has an equal chance at winning, what is your probability of not winning?
Answer:
the probability of not winning is 0.9946
Step-by-step explanation:
The computation of the probability of not winning is shown below:
The Probability of winning is
= 7 ÷ 1302
So, the probability of not winning is
= 1 - 7 ÷ 1302
= (1302 - 7) ÷ 1302
= 1295 ÷ 1302
= 165 ÷ 186
= 0.9946
Hence, the probability of not winning is 0.9946

Rosa want to buy a new TV priced at 499.99 The TV is on sale for 15% off but the cashier informs her that if she applies for a store credit card she can have an additional 10% off. How much will Rosa pay after the discounts and 6% tax have been applied? Write and solve an equation to find the final price.
Answer:
$405,44
Step-by-step explanation:
Equation: 499.99 - (499.99 x 15/100) - 1/10[499.99-(499.99 x 15/100)] + 6/100{1/10[499.99-(499.99 x 15/100) = x
Steps: x = (15 x 499.99)/100 = $74.9985
499.99 - 74.9985 = $424,9915
x = (424,9915 x 10)/100 = $42,49915
424,9915 - 42,49915 = $382,49235
x = $22,949541
382,49235 + 22,949541 = $405,441891
That can be rewritten as $405,44.

Divide 1 hour in the ratio 20%to 80%
Answer:
12min 48min
Step-by-step explanation:
1hr=60min
60x20%=12min
60x80%=48min
Answer:
1 : 4
Step-by-step explanation:
20% of 60 mins = 20/100*60 = 12 mins.
80% of 60 mins =80/100*60 = 48mins.
A statue of George Washington is also in Druid Hill Park. If a girl stands 15 m away from the statue, and places a mirror 12 m from the statue (3 m from her feet), she can see the top of the statue in the mirror. The girl's height is 5.5 ft. How tall is the statue?
Answer:
The statue is 22ft tall.
Step-by-step explanation:
Here we will have two similar triangle rectangles.
One is made between the girl's feet, the mirror, and the girl's eyes.
So in this case the catheti are:
the distance between the girl and the mirror (3 m) and the height of the girl (5.5 ft)
The other triangle rectangle has the vertices:
The mirror, the base of the statue, and the top of the statue.
Such that the catheti of this triangle are the distance between the base of the statue and the mirror (12m) and the height of the statue (we want to know this, let's call this X for the moment).
Because the triangles are similar, this means that there is a proportionality constant between each correspondent side, let's call this k.
Then the distance between the girl and the mirror must be k times the distance between the base of the statue and the mirror:
3m = k*12m
And the height of the girl must be k times the height of the statue.
5.5ft = k*X
You can see that we have different units, this does not matter because k is a dimensionless constant.
With the first equation we can find the value of k
3m = k*12m
3m/12m = k
(3/12) = 1/4 = k
Now we can replace this in the other equation to get:
5.5ft = (1/4)*X
Solving this for X we get:
(5.5ft)*4 = X
22ft = X
The height of the statue is 22ft.

Hi if you answer please explain how you got the answer thanks! :)
Answer:
B: 60,000
Step-by-step explanation:
Since there was a total of 200,000 votes, we can create this equation, since we also know the ratio between the two candidates:
7x + 3x = 200,000
x can be seen as a common factor between the two candidates that can be used to express their difference
We can now further simplify this equation by combining like terms and solving for x:
10x = 200,000
x = 200,000/10
x = 20,000
Now, to find the total number of votes cast for Bob Tanks, we multiply x by 3, since it says that Julie Sanders won by a ratio of 7:3, which means she had 7 in the ratio and Bob had the 3.
3x = 3(20,000) = 60,000
The answer is B: 60,000.
Answer: 60,000
Step-by-step explanation:
The easiest way to solve this problem is to use equations
Since we know the ratio of Julie's votes to Bob's votes is 7:3 and the total is 200,000 we can use this equation 200,000 (number of votes) = 7x(Julie's votes) + 3x(Bob's votes)
After you solve it you get x=20,000
Then,
You put that back into Bob's votes and you get 60,00
Hope this helps :)
