Answer:
648 cups, 3 fluid ounces
Step-by-step explanation:
You need to know that 1 cup = 8 fluid ounces (fl. oz).
convert to fl. oz:
1296 cups = 10368 fl.oz.
total fl.oz. = 10368+6 = 10374
10374 / 2 = 5187 fl.oz.
= 648 cups and 3 fluid ounces
Triangle TUV has sides that measure 12, 8, and 6. Triangle XYZ has sides that measure
8,6,and 3. Can triangles TUV and XYZ be similar polygons?
A. Yes. Regardless of the lengths of the sides, you can always join them by angles that
form similar triangles.
B. Yes. The ratio of 12:6 is the same as the ratio of 6:3.
C. No. The ratio 12:6 is the same as the ratio of 6:3.
D. No. The ratio of the longest sides is 12:8 and the shortest sides is 6:3.

A recreational court is twice as long as it is wide. if the perimeter is 210 feet, find the width and length .
Answer:
The court has a length of 70 feet, and a width of 35 feet.
Step-by-step explanation:
We know two things:
the the length is twice the width
l = 2w
We also know that the perimeter is 210 feet. Noting that the perimeter of a rectangle is equal to twice its length plus twice its width, we can say:
210 = 2w + 2l
Now we can substitute the first definition of l into the second equation:
210 = 2w + 2(2w)
And now we can solve for w:
210 = 2w + 2(2w)
210 = 2w = 4w
210 = 6w
w = 210 / 6
w = 35
Now that we have w, we can plug that into our first little equation to find l:
l = 2w
l = 2 × 35
l = 70
So the width of the court is 35 feet, and it's length is 70.

Step-by-step explanation:
Cosine is a trigonometric identity. It is a ratio of the adjacent side and hypotenuse of a right triangle.
The adjacent side to angle Θ is 12. The hypotenuse of this triangle is 20.
cosΘ in this case would be 12/20.

Answer:
x = 67
Step-by-step explanation:
2x - 17 + 63 = 180 {Linear pair}
2x + 46 = 180
2x = 180 - 46
2x = 134
x = 134/2
x = 67
[tex]\color{plum}\bold{x \tt \: = 67}[/tex]
Steps to derive the correct solution :∠63° and ∠(2x-17)° are a linear pair, so their sum will be equal to 180°.
Which means :
[tex] = 63 + 2x - 17 = 180[/tex]
[tex] = 63 + 2x = 180 + 17[/tex]
[tex] = 63 + 2x = 197[/tex]
[tex] = 2x = 197 - 63[/tex]
[tex] = 2x = 134[/tex]
[tex] = x = 67[/tex]
Let us place 67 in the place of x and see if the substitution is equivalent to 180° :
[tex] = 63 + 2 \times 67 - 17 = 180[/tex]
[tex] = 63 + 134 - 17 = 180[/tex]
[tex] = 63 + 117 = 180[/tex]
[tex] = 180 = 180[/tex]
Thus, the value of x we found out is correct.
Therefore, x = 67
How is Solve this equation
M + A = 68 and M = A + 24
Hi there! :)
[tex]\large\boxed{A = 22 \text{ , } M = 46 }[/tex]
We can solve by setting both equations equal to the same variable.
We are given that M + A = 68 and M = A + 24. The easiest variable to set both equal to would be M.
Rearrange the first equation by subtracting A from both sides:
M = -A + 68
Now that both equations equal to M, we can set the two equal to each other:
-A + 68 = A + 24
Add A to both sides:
68 = 2A + 24
Subtract 24 from both sides:
44 = 2A
Divide both sides by 2:
A = 22.
Plug this back into an equation to solve for M:
M + 22 = 68
M = 68 - 22
M = 46.

Step-by-step explanation:
Given the data:
6416; 1550; 2110; 9351; 21830; 4299; 5945; 5722; 2827; 2046; 5481; 5202; 5855; 2749; 10011; 6356; 27000; 9415; 7683; 3202; 17502; 9200; 7380; 18315; 6557; 13714; 17767; 7491; 2769; 2861; 1264; 7284; 28165; 5081; 11624
Using calculator :
Sample mean, m= 8629.25714
Sample standard deviation, s = 6943.92362
1.) T test distribution ;
Sample size, n = 35
Confidence interval (C. I) : m ± Zcritical * s/sqrt(n)
n = sample size = 35
Tn-1,0.025 = t34, 0.025 = 2.0322
C.I = 8629.25714 ± 2.0322 * (6943.92362 / sqrt(35))
C.I = 8629.25714 ± 2385.2689
Lower bound = 8629.25714 - 2385.2689 = 6243.98824
Upper bound = 8629.25714 + 2385.2689 = 11014.52604
(6243.99, 11014.53)
Error bound :
E = t34, 0.025 * (s/sqrt(n))
E = 2.0322 * 6943.92362 / sqrt(35)
E = 2.0322 * 1173.7373
E = 2385.27
C.)
If n = 500
C.I = 8629.25714 ± 2.0322 * (6943.92362 / sqrt(500))
C.I = 8629.25714 ± 631.08285
Lower bound = 8629.25714 - 631.08285 = 7998.17429
Upper bound = 8629.25714 + 631.08285 = 9260.33999
(7998.17, 9260.34)
Error bound :
E = t34, 0.025 * (s/sqrt(n))
E = 2.0322 * 6943.92362 / sqrt(500)
E = 2.0322 * 310.54170
E = 631.08
Both the error margin and the confidence interval reduces due to large sample size.
What expression can be used to find the nth term in the sequence 5,7,9, 11,...?
2n - 3
n + 2
n - 3
2n + 3
Answer:
The required expression which can be used to find the nth term in the sequence is:
[tex]a_n=2n+3[/tex]
Hence, the fourth option i.e. 2n+3 is the correct option.
Step-by-step explanation:
Given the sequence
5, 7, 9, 11,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]7-5=2,\:\quad \:9-7=2,\:\quad \:11-9=2[/tex]
The difference between all the adjacent terms is the same and equal to
d = 2
So
a₁ = 5d = 2Thus, the nth term of the sequence is
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substitute a₁ = 5 and d = 2 in the sequence
[tex]a_n=2\left(n-1\right)+5[/tex]
[tex]a_n=2n+3[/tex]
Therefore, the required expression which can be used to find the nth term in the sequence is:
[tex]a_n=2n+3[/tex]
Hence, the fourth option i.e. 2n+3 is the correct option.

31 is the right answer.Penny reads 13 pages in 1/4 hour. What is the unit rate for pages per hour? For hours per page?
Answer:
52 pages per 1 hour
Step-by-step explanation:
If Penny reads 13 pages in 1/4 of an hour you need to multiply 13 by 4 to see how many pages she will read in 1 hour.
The unit rate:
52 pages per hour.
0.02 hours per page.
What is division?One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.
To find the unit rate of pages per hour, we need to convert 1/4 hour to hours first.
1/4 hour = 0.25 hour
Then, we can use the formula:
Unit rate = Pages ÷ Time
Unit rate = 13 pages ÷ 0.25 hour
Unit rate = 52 pages per hour
To find the unit rate of hours per page, we can use the reciprocal of the previous unit rate:
Unit rate = Time ÷ Pages
Unit rate = 0.25 hour ÷ 13 pages
Unit rate = 0.0192 hours per page
Rounded to the nearest hundredth, the unit rate is 0.02 hours per page.

6. The length of a football field is 30 yards more than its width.
Express the length of the field in terms of its width. If the perimeter
of the field is 340 yards. find the width of the field. I
Answer:
the width be 70 yards
Step-by-step explanation:
The computation of the width of the field is as follows:
As we know that
The Perimeter of the rectangle is
= 2 × (length + width)
Where
Perimeter is 340 yards
Let us assume the width be x
So, the length would be x + 30
Now put these values to the above formula
340 = 2 × (x + x + 30)
340 = 2 × (2x + 30)
340 = 4x + 60
4x = 280
x = 70
The length would be
= 70 + 30
= 100
Hence, the width be 70 yards

5. Murphy obtains a 15/5 balloon mortgage to finance $113,500 at 4.95%. How much principal and interest will he have already pald when his balloon payment is due? (2 points)
$85,433.10
O $70,863.13
O $52,781.40
O $53,676.00
Answer:
$278.15×60= $16688.969
Step-by-step explanation:
Murphy has a 15/5 balloon mortgage plan therefore he would make constant payments monthly for five years and then pay the balance of the loan/balloon payment for the 10 years left in bulk
To calculate principal+interest on loan before balloon payment is due, we simply calculate Murphy's constant/monthly payments for the 15 year loan amortization and multiply by number of payments before balloon payment is due:
Formula for monthly payments
A= P×r×r(1+r)^n/(1+r)^n-1
Where A= monthly payments
P= mortgage loan value
r= interest rate on loan
n= number of payments = 15×12= 180 monthly payments
Substitute :
A= $113500×0.0495×0.0495(1+0.0495)^180/(1+0.0495)^180-1
A= $113500×0.0495×296.104/5980.90
A= $113500×0.0495×0.049508
A= $278.15
To calculate our principal and interest before balloon payment, we multiply by number of payments(5×12=60 payments) before due balloon payment
60×$278.15= $16688.969

a sequence of payment made at equal time period is a/an'????
Answer:
Annuity.
Step-by-step explanation:
A sequence of payment made at equal time period is called an annuity.
Basically, annuity can be calculated using the compound interest formula. It is given by the mathematical expression;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Additionally, the time period between each payment is called payment period.
The term of an annuity refers to the time from the beginning of the first payment made by an individual to the end of the last payment period.
