Answers

Answer 1
The answers is 2.8 and or 2.83 which ever your answer chose is 
Answer 2

Answer:

2.8

Step-by-step explanation:

From the congruence statement, we see that AB corresponds with EF; this means they will be congruent.

To find the measure of FE, we will find the distance between points A and B using the distance formula:

[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Using our coordinates for A and B, we have

[tex]A(0,2)\text{and }B(2, 4)\\\\d=\sqrt{(4-2)^2+(2-0)^2}=\sqrt{2^2+2^2}\\\\=\sqrt{4+4}=\sqrt{8}=2.828427\approx 2.8[/tex]

Matt reasoned that he can write 9/1000 as 0.9. Is he correct?

Answers

The answer is no, he's not correct.

You're looking at 9/1000, which means you move the (invisible) decimal point after 9 three places to the left (because you're dividing and there are 3 zeros after the 1 in 1000). This would give you 0.009.
No he is not correct because 9/1000 Is 0.009. That is a different value than 0.9. 0.9 is 9/10.

A ball is launched into the sky at 19.6 feet per second from a 58.8 meter tall building. The equation for the ball’s height, h, at time t seconds is h = -4.9t2 + 19.6t + 58.8 . When will the ball strike the ground?

Answers

A ball is launched into the sky at 19.6 feet per second from a 58.8 meter tall building. " 

Is that a typo, or a real mixture of units? 

The equation is only good if the launch speed is actually 19.6 m/s, so I'll assume that. 

It will strike the ground when the ball's height = 0 m !!! 

-4.9t² +19.6t + 58.8 = 0 

You can always use the "quadratic formula" if you want to, but ... 

This set of numbers is beloved by physics teachers everywhere. Everything divides by -4.9 

t² - 4t -12 = 0 

...and factorizes easily: 

(t + 2)(t - 6) 

So t = 6 or t = -2 Disregard the negative solution. 

The ball will strike the ground at t = 6 seconds

P(n) models the fundraiser's profit (in dollars) if n tickets are sold. A negative profit means the expenses exceeded the income from tickets.

P(n) = 70n-1500 

what is the price of a single ticket

Answers

P(n) = 70n - 1500....let me break this down for you

profit = revenue - expenses
so the revenue, what is made from selling tickets.....70n....where n represents the number of tickets....the 70 represents the cost of each ticket.

the 1500 is the expenses. So for them to make a profit, they would have to sell more then $ 1500 worth of tickets.

the price of a single ticket is $ 70 <==

The price of a single ticket is given by the expression [tex]\( \frac{70n - 1500}{n} \),[/tex] where n represents the number of tickets sold.

To find the price of a single ticket, we need to understand that the profit P(n) represents the income from ticket sales.

In the given equation [tex]\( P(n) = 70n - 1500 \)[/tex], n represents the number of tickets sold, and P(n) represents the profit from selling n tickets.

If we divide the total profit P(n) by the number of tickets n, we can find the price of a single ticket.

So, the price of a single ticket is given by:

[tex]\[ \text{Price of a single ticket} = \frac{P(n)}{n} \][/tex]

Substituting [tex]\( P(n) = 70n - 1500 \)[/tex], we get:

[tex]\[ \text{Price of a single ticket} = \frac{70n - 1500}{n} \][/tex]

Now, the price of a single ticket is dependent on the number of tickets sold, so we cannot determine a specific price without knowing the value of n. However, we can say that as the number of tickets sold increases, the price per ticket decreases due to the fixed costs (expressed by the constant term -1500) being spread out over a larger number of tickets.

During a storm, why do you see the flash of lightning before you hear the roar of thunder? What would it mean if you saw the flash of lightning and heard the roar of thunder at the same time? What would it mean if there were many seconds in between the flash of lightning and the roar of thunder?

Answers

The speed of light is faster than the speed of sound. So that's why you see a flash of lightning before the roar of thunder. If you heard it at the same time as you saw it, well I will be praying for you. It would literally be exactly where you are. If you hear the thunder a long time after the flash, it means the lightning is far away.

T/5=miles away when T is time from the strike of lightning to hearing thunder 

Final answer:

You see lightning before hearing thunder due to the faster speed of light compared to sound. A simultaneous occurrence suggests the lightning is very close, while a delay indicates distance, with every five seconds equaling approximately one mile.

Explanation:

During a storm, you see the flash of lightning before you hear the roar of thunder because light travels much faster than sound. Lightning, a massive discharge of electricity, heats and expands the air rapidly, creating the sound of thunder. The difference in the travel speeds of light (3 × 10⁸ meters per second) and sound means that we perceive these events at different times.

If you saw the flash of lightning and heard the roar of thunder at the same time, it would mean that the lightning strike occurred very close to your location, practically overhead. Conversely, a noticeable delay between the flash of lightning and the sound of thunder indicates that the lightning strike is farther away. Each 5-second gap between seeing lightning and hearing thunder equates to approximately one mile distance from the lightning strike.

To estimate the distance of a storm, you only need to know the speed of sound, as the speed of light is so fast that the time it takes for light to reach you is negligible for this calculation. This method of estimating distance helps understanding the physical phenomena and ensuring safety during storms.

A diver swims 5.875 feet up to the surface of the water. Which number represents the diver’s position in relation to the surface before swimming to the top?

Answers

Final answer:

In relation to the surface, before swimming up, the diver was -5.875 feet under the water. The negative sign implies that the diver was beneath the surface of the water.

Explanation:

The diver's position in relation to the surface before swimming to the top is represented by a negative number because swimming upwards implies moving in a positive direction. In this case, the diver was -5.875 feet from the surface before they started swimming up. This negative sign indicates that the diver was beneath the surface of the water.

find the values of x and y

Answers

Ok so 80 and 4x-y form a straight angle.
80+(4x-y)=180
4x-y=100

(4x-y) and (x+2y+10) also form a straight angle, but we know that 4x-y=100
100+x+2y+10=180
x+2y+110=180
x+2y=70

Now we have a system of equation
4x-y=100
x+2y=70

Solve the first equation for y
-y=-4x+100
y=4x-100

Substitute y
x+2(4x-100)=70
x+8x-200=70
9x=270

The values of [tex]x=30^{\circ}[/tex] and [tex]y=20^{\circ}[/tex].

Step-by-step explanation:

A Linear pair is a pair of adjacent angles formed when two lines intersect.

In the given figure, [tex]80^{\circ}[/tex] and  [tex]4x-y[/tex] , [tex]4x-y[/tex] and   [tex]x+2y+10^{\circ}[/tex] form a linear pair.

By linear pairs theorem, we have

[tex]80^{\circ}+4x-y=180^{\circ}[/tex]

[tex]4x-y+x+2y+10^{\circ}=180^{\circ}[/tex]

On solving we get,

[tex]4x-y=100^{\circ}[/tex]     ....(1)

[tex]5x+y=170^{\circ}[/tex]     .....(2)

Now, to solve equation (1) and (2) by simultaneously; we get [tex]x=30^{\circ}[/tex]

putting the value of x in equation 1 we get,

[tex]4x-y=100^{\circ}[/tex]

[tex]4\cdot 30^{\circ}-y=100^{\circ}[/tex]

[tex]120^{\circ}-y=100^{\circ}[/tex]

On simplify we have, [tex]y=20^{\circ}[/tex]

Therefore, the values of x and y are: [tex]30^{\circ}[/tex] and [tex]20^{\circ}[/tex]

108 centimeters 1.08 meters equation and exponent

Answers

m=cm x10^2 cm=mx10^-2

To convert 108 centimeters to meters, divide by 100, since 100 centimeters equals 1 meter. Thus, 108 cm equals 1.08 meters, and the exponential form of 1.08 is 1.08 x 10⁰.

To convert 108 centimeters to meters, we use the fact that 100 centimeters is equal to 1 meter. If we have 108 centimeters and we want to express that in meters, we divide 108 by 100, since there are 100 centimeters in a meter.

Thus, 108 centimeters is equivalent to 1.08 meters. When we write 1.08 as an exponent, we express it as 1.08 imes 100, because any number to the power of 0 is 1, and thus the exponent does not change the value of 1.08.
