What is the total surface area of the figure shown
Answer: The total surface area is 2784 sq. inches.
Step-by-step explanation: We are given to find the total surface area of the given figure.
Let us divide the figure into two two cuboids 1 and 2 as shown in the attached figure.
We know that the surface area of a cuboid with length 'l', breadth 'b' and height 'h' is given by
[tex]S.A.=2(l_1b_1+l_1h_1+h_1b_1).[/tex]
The dimensions of the cuboid 1 are
[tex]length,~l_1=14~\textup{inches},\\\\breadth,~b_1=12~\textup{inches},\\\\height,~h_1=24-10=14~\textup{inches}.[/tex]
The dimensions of the cuboid 2 are
[tex]length,~l_2=30~\textup{inches},\\\\breadth,~b_1=14~\textup{inches},\\\\height,~h_1=10~\textup{inches}.[/tex]
Therefore, surface area of cuboid 1 is given by
[tex]S.A_1\\\\=2(l_1b_1+l_1h_1+h_1b_1)\\\\=2(14\times 12+14\times 14+14\times 12)\\\\=2(532)\\\\=1064~\textup{sq. inches.}[/tex]
And surface area of cuboid 2 is given by
[tex]S.A_2\\\\=2(l_2b_2+l_2h_2+h_2b_2)\\\\=2(30\times 14+30\times 10+14\times 10)\\\\=2(420+300+140)\\\\=2(860)\\\\=1720~\textup{sq. inches}.[/tex]
Thus, the total surface area of the figure is
[tex]S.A.=S.A_1+S.A_2=1064+1720=2784~\textup{sq. inches}.[/tex]

Find all the zeros of the equation.
-3x^4+27x^2+1200=0
I don't really understand this. Please show me the steps! Thanks!
Final answer:
The zeros of the equation -3x^4+27x^2+1200=0 are x = 16 and x = -25.
Explanation:
To find the zeros of the equation -3x^4+27x^2+1200=0, we can use the quadratic formula. Let's set our equation equal to zero:
-3x^4+27x^2+1200=0
Now, we can use the quadratic formula, which states that for an equation in the form ax^2+bx+c=0, the solutions are given by:
x = (-b ± sqrt(b^2-4ac))/(2a)
Applying this formula to our equation, we get:
x = (-27 ± sqrt(27^2-4(-3)(1200)))/(2(-3))
Simplifying further, we have:
x = (-27 ± sqrt(729+14400))/(-6)
x = (-27 ± sqrt(15129))/(-6)
x = (-27 ± 123)/(-6)
So the two solutions are:
x = (-27 + 123)/(-6) = 16
x = (-27 - 123)/(-6) = -25

Two jets leave an airport at the same time, flying in opposite directions. The first jet is traveling at three hundred seventy-seven mph and the other at two hundred seventy-five mph. How long will it take for the jets to be 9128 miles apart?
Final answer:
To find the time it takes for two jets to be 9128 miles apart, calculate their combined speed and divide the total distance by this speed, resulting in approximately 14 hours.
Explanation:
To find the time taken for the jets to be 9128 miles apart:
Calculate the combined speed of the two jets by adding their speeds together: 377 mph + 275 mph = 652 mph.
Divide the total distance of 9128 miles by the combined speed of the jets to get the time taken: 9128 miles ÷ 652 mph ≈ 14 hours.

Two seventh grade math classes are competing in an academic challenge. Each class will randomly select one class member to compete each week. Each class has 26 students, and half of the students in each class are boys.
The classes want to design a simulation that will give the probability of both class members participating in the academic challenge being girls. Two possible simulations are given below.
Simulation 1: Flip a coin 26 times. If it lands on heads, count the flip as a girl. If it lands on tails, count the flip as a boy. Count how many times the coin lands on heads.
Simulation 2: Use two standard decks of cards. Randomly draw one card from each deck. Each diamond or heart drawn will represent a girl. Each spade or club drawn will represent a boy. After the two cards are drawn, they are replaced and the decks are shuffled. Count how many times a heart or diamond is drawn from both decks for 100 trials.
(Simuation 1 or Simulation 2) would be best to use to simulate a girl being randomly selected from each class to participate in the academic challenge. Based on this simulation, the probability that two girls will be selected is about (15%, 50%, 25%, or 75%).
The best simulation for the probability of selecting two girls is Simulation 2, which uses two standard decks of cards, with hearts and diamonds representing girls. The probability that both selected members are girls is 25%.
To simulate the probability that both class members participating in the academic challenge are girls, Simulation 2 would be more appropriate. Since each class has half boys and half girls, just like a standard deck of cards has half red suits (hearts and diamonds representing girls) and half black suits (spades and clubs representing boys), this simulation effectively mirrors the class demographics.
To calculate the probability of selecting a girl from both classes, consider the probability of drawing a heart or diamond from one deck, which is 1/2 or 0.5. Since the events are independent (what happens in one draw does not affect the other), we can multiply the probabilities for the two events: 0.5 (probability of a girl from Class A) * 0.5 (probability of a girl from Class B) = 0.25. Therefore, the probability of both selected members being girls is 25%.

Noah spent some of his allowance on Monday. He spent 1/6 of his allowance on Tuesday and 3/6 of it on Friday. Noah has none of his allowance money left. What fraction of his allowance did he spend on Monday?
Let us represent the allowance spent by Noah on Monday by the letter "x".
We know that all the fractions must always add up to 1 in such questions.
Thus, if Noah spent 1/6 of his allowance on Tuesday and 3/6 of it on Friday and he spend x amount on Monday, then these spendings must add up to 1.
In other words,
[tex] x+\frac{1}{6}+\frac{3}{6}=1 [/tex]
[tex] x+\frac{1+3}{6}=1 [/tex]
Thus, [tex] x+\frac{4}{6}=1 [/tex]
[tex] \therefore x=1-\frac{4}{6}=\frac{6-4}{6}=\frac{2}{6}=\frac{1}{3} [/tex]
Thus Noah spent a third or [tex] \frac{1}{3} [/tex] of her allowance on Monday.

If 5/9 of a tank can be filled in 2 minutes, how many minutes will it take to fill the whole tank ?
If 5/9 of a tank can be filled in 2 minutes, it would take 3.6 minutes to fill the whole tank by setting up a proportion and solving for the time.
Explanation:If 5/9 of a tank can be filled in 2 minutes, then to find the time it takes to fill the whole tank, we can set up a proportion. Since time is directly proportional to the amount of the tank filled, we have the following relationship:
Fraction of tank filled / Time to fill that fraction = 1 (whole tank) / x minutes
So, 5/9 of the tank is to 2 minutes as 1 whole tank is to x minutes:
(5/9) / 2 = 1 / x
Cross-multiplying gives us:
5x = 18
Dividing both sides by 5:
x = 18/5
x = 3.6 minutes
Therefore, it would take 3.6 minutes to fill the whole tank.
Final answer:
To find out how long it takes to fill the entire tank, set up the proportion of (5/9) of the tank in 2 minutes to (9/9) of the tank in x minutes, which gives x = 3.6 minutes for the whole tank to be filled.
Explanation:
If 5/9 of a tank can be filled in 2 minutes, we can set up a direct proportion to find out how long it would take to fill the entire tank. We are trying to find the time required to fill 9/9 (or the whole tank) if 5/9 takes 2 minutes. To solve this, we calculate:
Set up the proportion where the fraction of the tank filled is directly proportional to the time taken: (5/9) / 2 = (9/9) / x minutes.
Now we solve for x, which represents the total time to fill the tank: x = (2 minutes * 9/9) / (5/9).
Simplify the right side: x = 2 minutes * (9/5).
Calculate the value of x: x = 3.6 minutes.
Therefore, it will take 3.6 minutes to fill the entire tank.

A guy wire is stretched from the top of a tower to a point 10 yards from the base of the tower. The wire makes an angle of 65° with the ground. Draw a diagram and find the length of the guy wire. 4.2 yd. 11.0 yd. 23.7 yd.
Answer:
23.7 yards
Step-by-step explanation:
Given :A guy wire is stretched from the top of a tower to a point 10 yards from the base of the tower. The wire makes an angle of 65° with the ground
To Find: Draw a diagram and find the length of the guy wire
Solution :
Refer the attached figure
We are given that A guy wire is stretched from the top of a tower to a point 10 yards from the base of the tower i.e. AC = 10 yards
We are also given that wire makes an angle of 65° with the ground i.e. ∠BAC = 65°
Now to find the length of the guy wire i.e. AB
We will use trigonometric ratio.
[tex]cos\theta = \frac{Base}{Hypotenuse}[/tex]
[tex]cos 65 ^{\circ} = \frac{AC}{AB}[/tex]
[tex]0.4226= \frac{10}{AB}[/tex]
[tex]AB= \frac{10}{0.4226}[/tex]
[tex]AB= 23.66[/tex]
Thus AB = 23.66 yards ≈ 23.7 yards
Hence the length of the guy wire is 23.7 yards
