Answer:
Option B
Step-by-step explanation:
The reason is because the surface area is not including the base of the pyramid and the top of the prism.
Option b. she left out one of the faces of the solid she should have simplified 2((5)(7))+2((6)(7))+2[1/2(5)(9.3)]+2[1/2(6)(9.2)]+(5)(6)
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to the surface area of the pyramid not including the base plus the surface area of the prism not including the top

What is the height of the hovercraft at the time of takeoff?
Answer:

Step-by-step explanation:
The height (in meters), h(x) of a hovercraft x seconds after takeoff, is modeled by:
[tex]h(x)=-3(x-3)^2+108[/tex]
We are to determine its height at the time of takeoff.
Now, at the time of takeoff, x=0.
We substitute x=0 to solve for h.
[tex]h(0)=-3(0-3)^2+108\\=-3(-3)^2+108\\=-3(9)+108\\=-27+108\\=81$ meters[/tex]
The height of the hovercraft at takeoff is 81 meters.

Find the measure of arc QR
doing quests, sorry luv. but what does it look like?
C. 104°. The measure of arc QR is equal to 104°.
In Mathematics and Euclidean Geometry, the inscribed angle of a circle is equal to one-half of the central angle or intercepted arc of a circle. This ultimately implies that, the measure of an inscribed angle is one-half the measure of the arc it intercepts based on the inscribed angle theorem.
Since angle S intercepts arc QR, the measure of the angle substended by the intercepted arc can be modeled by the following mathematical equation:
m∠S = 1/2(arc QR).
52 = 1/2 × arc QR
Arc QR = 2 × 52
Arc QR = 104°.

Answer:
x=9
Step-by-step explanation:
Looking at the diagram, we see that four angles are formed by the intersection of two lines. The angles highlighted in blue and green are therefore, vertical angles. We know that vertical angles have equal angle measures meaning that in this case, the measure of the blue angle is equal to the measure of the green angle. Using this, we can now solve for x:
7x+49=2x+94
7x-2x=94-49
5x=45
x=45/5
x=9

(-8)2 – (4)(0.250
200.25)
(-8)2 – (4)(0.25)0
2(0.25)
Answer:
Step-by-step explanation:
Given that,
0 = 0.25x² - 8x
This is a quadratic equation, since it has the highest power of x to be 2.
0.25x² - 8x = 0
Simplify this by bring out x
x(0.25x - 8) = 0
So, if a × b = 0, it is either a = 0 or b = 0, if the multiplication of two number is 0, then it is either one of the number is 0 or both numbers is 0
So,
x(0.25x - 8) = 0
x = 0. OR. 0.25x - 8 = 0
x = 0. OR. 0.25x = 8
x = 0. OR. x = 8 / 0.25
x = 0. OR. x = 32.
So, the solution that describe the system is
0.25(0)² - 8(0)
OR
0.25(32²) - 8(32)

Do these rates form a proportion? Defend your answer.
66 songs: 6 hours
22 songs: 2 hours
Answer:
They form a proportion
Step-by-step explanation:
Take 66 songs and divide by 6 hours
66/6 = 11 songs per hour
Take 22 songs and divide by 2 hours
22/2 = 11 songs per hour
The rates are the same so they a proportional
The rates 66 songs in 6 hours and 22 songs in 2 hours do form a proportion, as both simplify to the same ratio of 11 songs per hour, indicating a consistent linear relationship between the number of songs and listening time.
Explanation:The question asks if the rates of 66 songs in 6 hours and 22 songs in 2 hours form a proportion. To determine this, we check if the ratios are equivalent. The ratio for the first rate is 66 songs per 6 hours, which simplifies to 11 songs per hour (since 66 ÷ 6 = 11). The ratio for the second rate is 22 songs per 2 hours, which simplifies to 11 songs per hour (since 22 ÷ 2 = 11). Since both rates simplify to the same unit rate of 11 songs per hour, they indeed form a proportion. This shows that the rate at which songs are experienced is consistent across both periods, essentially indicating that the number of songs listened to scales linearly with the time spent listening.

PLEASE HELP ME!!!
I have a sock drawer with 16 socks. 6 are black, 8 are white and 2 are blue. What is the probability that I will randomly choose a white sock, put it to the side, and then randomly choose another white sock?
A. 7/30
B. 8/16
C. 7/15
D. 29/30
The probability of choosing one white sock and then another white sock from a drawer of 16 socks with 8 being white is 7/30, calculated by multiplying the probability of each event: (1/2) * (7/15).
Initially, there are 8 white socks out of 16 total socks in the drawer. After putting one white sock aside, there are now 7 white socks left out of 15 total socks in the drawer.
The probability for each event is calculated separately:
The probability of picking a white sock first: 8/16 or 1/2.
Then the probability of picking another white sock: 7/15.
To find the overall probability of both events occurring in sequence (one after the other), we multiply the probabilities of the two independent events:
(1/2) * (7/15) = 7/30.
So the correct answer is A. 7/30.
If line L bisects AB at point M, and if AM = 4x and MB = 5x - 4. then find AB.
By setting up and solving the equation 4x = 5x - 4, we can find the value of x. Substituting the value of x into the expression for AM or MB, we can find the length of AB.
Explanation:In order to find AB, we need to solve for x since AM and MB are given in terms of x. Since line L bisects AB at point M, AM and MB should be equal. So, we can set up the equation 4x = 5x - 4 and solve for x.
4x = 5x - 4
-x = -4
x = 4
Now that we have the value of x, we can substitute it back into one of the expressions for AM or MB to find the length of AB. Using AM = 4x, we have AB = AM + MB = (4 * 4) + (5 * 4 - 4) = 16 + 16 = 32.
Therefore, AB is 32 units long.

Porcentagem No dia 15/05/2020 as 18h e 40min o G1 divulgou que a Paraíba tem 3.739 casos confirmados e 170 mortes por coronavírus. Qual a porcentagem de mortos no Estado da Paraíba em relação a quantidade de casos confirmados ?
Answer:
The percentage of deaths in relation to the number of cases is 4.55%.
Step-by-step explanation:
The proportion of deaths is the number of deaths divided by the number of cases(Proporção de mortes é o numero de morte dividido pelo de casos).
The percentage is the proportion multiplied by 100.
In this question:
3739 cases, 170 deaths
170/3739 = 0.0455
0.0455*100 = 4.55%
The percentage of deaths in relation to the number of cases is 4.55%.
Which is the equation of an ellipse centered at the origin with foci on x-axis, major axis of length 12 and minor axis of length 8?
Answer:
[tex]\frac{x^{2} }{36}+\frac{y^2}{16}=1[/tex]
Step-by-step explanation:
Center of the ellipse is at origin (0, 0)
So (h, k) = (0, 0)
Length of major axis = 12
2a = 12
⇒ a = 6
Length of minor axis = 8
⇒ 2b = 8
⇒ b = 4
Since focus is on the x-axis, so it's a horizontal ellipse.
Equation of the horizontal ellipse is in the form of,
[tex]\frac{(x-h)^{2} }{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
By substituting the given values of a, b, and (h, k)
[tex]\frac{(x-0)^{2}}{6^2}+\frac{(y-0)^2}{4^2}=1[/tex]
[tex]\frac{x^{2} }{36}+\frac{y^2}{16}=1[/tex]

Four friends went to a park to fly kites. Asher stood 50 feet due west of the flagpole. Baxter stood 50 feet due north of Asher. Cranby stood 100 feet due East of Baxter. Dudley stood 50 feet due south of Cranby. How far is Dudley from the flagpole
Answer:Dudley is 50 feet from the flagpole.
Step-by-step explanation:
The situation is represented in the attached diagram. FL represents the flagpole.
A represents the position of Asher.
B represents the position of Baxter.
C represents the position of Cranby.
D represents the position of Dudley.
Looking at the diagram, Dudley is at the same level with Asher but eastwards of the flagpole. The distance of Dudley from the flagpole would be
100 - 50 = 50 feet
Final answer:
Dudley is 100 feet east from the flagpole after the friends have each moved from their starting positions.
Explanation:
The question describes four friends at different locations in relation to a flagpole, and we are asked to determine how far Dudley is from the flagpole after following the described steps by the friends. To solve this, we can visualize or draw a diagram to represent the positions of friends and use the Pythagorean theorem to find the distance Dudley is from the flagpole.
Asher is 50 feet due west of the flagpole.Baxter is 50 feet due north of Asher.Cranby is 100 feet due East of Baxter.Dudley is 50 feet due south of Cranby.First, let's determine the position of Cranby.
Since Baxter moved 50 feet north from Asher's position and then Cranby moved 100 feet east from Baxter's position, we can see that Cranby is 100 feet east and 50 feet north of the flagpole.
Dudley, standing 50 feet south of Cranby, would thus be at the same north-south position as the flagpole but still 100 feet to the east.
Therefore, Dudley is 100 feet east of the flagpole.
