The equation Tan (55°) = 15/b can be used to find the length of AC.
How can I find it?
Step-by-step explanation:
Assuming you want to solve for b,
tan(55)=15/b
b(tan 55)=15
b = (tan 55)/15
Solve the equation: 4x - 9x + 11 = -24. When you guys solve this, be sure to show your work.
Answer:
4x - 9x + 11 = -24
-5x + 11 = - 24
-5x = -24 - 11
-5x = -35
-5x/-5 = -35/-5
x = 7
Answer:
The answer is 7
Step-by-step explanation:
Firstly, you have to subtract 11 from -24, which is -35. Then, add the values with x. Which is -5. -35 divided by -5 equals 7. You can check the answer by doing (4*7)-(9*7)+11=-24

On the ceiling of a cavern, a stalactite grows downward 0.01 inches per year. Ten feet directly below on the cavern's floor, a stalagmite grows upward 0.005 inches per year. How many years will it take them to meet? Express your answer to the nearest hundredth. Your answer
Answer:
666.66 years
Step-by-step explanation:
In this scenario, we need to find at what year both of the stalagmite crystals are at the exact elevation in the cave. So we need an algebraic formula to calculate this. Since the crystal in the ceiling is at a height of 10 feet (height of the cave) and is growing down we need to subtract its growth from its starting position of 10ft. The second crystal is starting at an elevation of 0 and growing upward so we simply need to chart its growth and equal both equations together to find its meet-up point. In this algebraic equation, x will equal the number of years that we need to find.
[tex]10 - 0.01x = 0.005x[/tex] ... add 0.01x to both sides.
[tex]10 = 0.015x[/tex] ... divide both sides by 0.015
[tex]666.66 = x[/tex]
Finally, we can see that both crystals will meet-up after 666.66 years. If we plug this value into the equation we see that the crystals will meet-up at a point 3.33 ft above the cave floor.

A theme park sells entrance tickets. 2 adult tickets and 3 child tickets would cost a total of £72. 3 adult tickets and 1 child ticket would cost a total of £66. A family ticket costs £45 and allows entry for 2 adults and 2 children. How much cheaper is it to buy a family ticket than it would be to buy 2 adults and 2 child tickets?
I might get this wrong but 60 minus 45 equals 1515
Step-by-step explanation:
The family pack would be £15 cheaper from the normal package.
What is a system of equations?In algebra, two or more equations to be solved together (i.e., the solution must satisfy all the equations in the system). For a system to have a unique solution, the number of equations must equal the number of unknowns.
Given that, A theme park sells entrance tickets. 2 adult tickets and 3 child tickets would cost a total of £72. 3 adult tickets and 1 child ticket would cost a total of £66. A family ticket costs £45 and allows entry for 2 adults and 2 children.
Let A represents adults and C represents children,
Establishing system of equation,
2A+3C = 72
3A+C = 66
On solving the equation, we get,
A = 18 and C = 12
For 2 adults, cost = 18x2 = £36
For 2 children, cost = 12x2 = £24
Total cost = 36+24 = £60
In family pack, £45 allows entry for 2 adults and 2 children.
45 is 15 less 60
Hence, The family pack would be £15 cheaper from the normal package.

Victor has quarters, dimes and pennies in his pocket. He has three times fewer pennies than dimes and he has 4 fewer quarters than pennies. How many coins does he have total if they are worth $4.60
46 coins
D=30
p=10
Q=6
30+10+6=46
The total amount of coins is 46 coins
Let x represent the number of quarters, y represent the number of dimes and z represent the number of pennies.
Each quarter is worth $0.25, each dime is worth $0.1 and each penny is worth $0.01
Since Victor has three times fewer pennies than dimes, hence:
y = 3z
y - 3z = 0 (1)
Victor also has 4 fewer quarters than pennies, hence:
x = z - 4
x - z = -4 (2)
The total worth of the coin is $4.60, therefore:
0.25x + 0.1y + 0.01z = 4.60 (3)
Solving equations 1, 2 and 3 simultaneously gives:
x = 6, y = 30, z = 10
Total coins = 6 + 30 + 10 = 46
Therefore there are 6 quarters, 30 dimes and 10 pennies

Step-by-step explanation:
Freida’s credit card has an APR of 13. 73%, and it calculates her finance charge by using the daily balance method and a 30-day billing cycle. On September 1st, Freida had a balance of $449. 22. During the month of September, she made a payment of $85. 33 and a purchase of $60. 99. How much greater will her September finance charge be if the purchase occurred on September 7th and the payment occurred on September 20th than it would be if the payment occurred on September 7th and the purchase occurred on September 20th? a. $0. 13 b. $0. 41 c. $0. 72 d. $0. 28.
The September finance charge will be greater by $0.41 if the purchase occurred on September 7th and the payment occurred on September 20th than the payment occurred on September 7th and the purchase occurred on September 20th.
What is the average daily balance method?The average daily balance totals each day's balance for the billing cycle and divides by the total number of days in the billing cycle.
When the payment occurred on 7th and purchase on 20th:
Balance in between September 1st and September 7th = $449.22
Balance in between September 7th and September 20th =449.22-85.33=$363.89
Balance in between September 20th and September 30th = 363.89+60.99
=$424.88
So, the balance on which interest will be applied according to the daily balance method = (449.22 * 6+363.89 * 13+424.89 *11)/30 = $403.322
Interest on this balance = 403.22 * (13.73/12) * (1/100) = $4.615
Similarly, when the payment occurred on the 20th while purchasing on the 7th:
The balance on which interest will be applied according to the daily balance method = (449.22 * 6 + 510.21 * 13 + 424.88*6)/30 = $395.911
Interest on this balance = $395.911 *(13.73/12) * (1/100) = $4.199
Difference between interests = $0.41
Therefore, the September finance charge will be greater by $0.41 if the purchase occurred on September 7th and the payment occurred on September 20th than the payment occurred on September 7th and the purchase occurred on September 20th.

salary?
Answer:
Monthly salary: $5,617; Weekly salary: $1,296
Step-by-step explanation:
Since there are 12 months in a year, you would divide the number of months by the salary.
67400/12x≈5617
The monthly salary is about $5,617.
Since there are about 52 weeks in a year, you would divide the number of weeks by the salary.
67400/52x≈1296
The weekly salary is about $1,296.
i need to know what the volume of a cylinder that's radius is 5 yd and height of 11 yd
Answer:
The volume is [tex]275\pi\text{ yd}^3[/tex] or [tex]863.5\text{ yd}^3[/tex]
Step-by-step explanation:
The formula for the volume of a cylinder is [tex]V=\pi r^2 h[/tex], where r is the radius and h is the height. From the information provided, we have:
[tex]r=5 \text{ yd}\\h=11\text{ yrd}[/tex]
Using our equation, we get:
[tex]V=\pi (5)^2(11)\text{ yd}^3\\V=275\pi\text{ yd}^3\\V\approx 863.5\text{ yd}^3[/tex]

Answer:
A = bh
Plug in what we know:
18 1/3 = 3 1/3b
Divide 3 1/3 to both sides:
(18 1/3) / (3 1/3) = b
Convert both of them into improper fractions:
55/3 / 10/3 = b
Flip the 2nd fraction and multiply:
55/3 * 3/10 = b
Multiply the numerators and denominators together:
165/30 = b
Convert to a mixed number:
b = 5 1/2
Step-by-step explanation:
Answer:
47 2/3 ÷ 7 1/3
make them improper fractions;
143/3 ÷ 22/3
Make 22/3 a reciprocal(flip the fraction upside down);
143/3 ÷ 3/22
now multiply across;
143/3 x 3/22 = 6 5/10 which simplifies to 6 1/2 feet.
Calculate the bearing of Y from X
Answer:
bearing of Y from X is 074°
Step-by-step explanation:
the bearing of Y from X is the clockwise measure of the angle from the northline N to Y , that is
180° - 106° = 74°
the 3- figure bearing of Y from X is 074°
The value of the bearing of Y from X will be 74°.
What is Supplementary angle?
The sum of two or more angle is 180 degree then the angle is called the Supplementary angle.
Given that;
The value of measure of ∠X = 106°
Now,
Since, The value of the bearing of Y from X will be calculated as;
∠X + ∠Y = 180°
106° + ∠Y = 180°
∠Y = 180° - 106°
∠Y = 74°
Thus, The value of the bearing of Y from X will be 74°.
