A plane is at a height of 300m and is 500m away from the airport . How much distance will it travel to land at the airport?

Answer:

36

Step-by-step explanation:

f * √g = k

12 * √64 = k

k = ± 96

g = k² / f² = (± 96)² / 16² = 36

Answer:

g = 36

Step-by-step explanation:

Given f is inversely proportional to [tex]\sqrt{g}[/tex] then the equation relating them is

f = [tex]\frac{k}{\sqrt{g} }[/tex] ← k is the constant of proportion

To find k use the condition when f = 12 , g = 64 , then

12 = [tex]\frac{k}{\sqrt{64} }[/tex] = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )

96 = k

f = [tex]\frac{96}{\sqrt{g} }[/tex] ← equation of proportion

When f = 16 , then

16 = [tex]\frac{96}{\sqrt{g} }[/tex] ( multiply both sides by [tex]\sqrt{g}[/tex]

16 × [tex]\sqrt{g}[/tex] = 96 ( divide both sides by 16 )

[tex]\sqrt{g}[/tex] = 6 ( square both sides )

g = 6² = 36

Answer:

$840 dollars

Step-by-step explanation:

Divide 540 by 9 to get the cost of 1 book then multiply it by 14

Answer:

$840

Step-by-step explanation:

[tex]\frac{14}{9}: \frac{y}{540}[/tex]

y × 9 = 540 × 14

9y = 7560

9y ÷ 9 = 7560 ÷ 9

y = 840

Part (a)

Refer to the diagram below to see the two triangles separated.

================================================

Part (b)

If the 3 meter portion is perpendicular to the horizontal portion, then the triangles are similar. We can prove this using the AA similarity theorem. One pair of angles would be the shared overlapping 25 degree angles. The other pair of congruent angles would be the two 90 degree angles. We only need two pairs of congruent angles to use AA. You could use three pairs (and the aptly named AAA theorem) but that's overkill in my book.

================================================

Part (c)

There are a few ways to approach this, but one way is shown below

y/3 = (8.4+6.6)/(6.6)

y/3 = 15/(6.6)

6.6y = 3*15 .......... cross multiply

6.6y = 45

y = 45/(6.6)

y = 6.81818 approximately

When rounding to one decimal place, we get y = 6.8

Answer:

z = 5 meters

Step-by-step explanation:

since the area = 25 [tex]m^2[/tex] and the only value is z, we have to multiply a number by itself that will equal  25 [tex]m^{2}[/tex].

z × z = 25 [tex]m^{2}[/tex]

20/10 goes to neither since it equals 2

0.02 goes to 2/100 since it is the same as 0.02

200 goes to neither because it is over 2/10 and 2/100

0.20 goes to 2/10 since 2/10 is equal to 0.20

Answer:

i=3/4

Step-by-step explanation:

Assuming that we are treating "i" as a variable and not the constant "i":

12+2i-i=9i+6

12+i=9i+6

12=8i+6

6=8i

8i=6

i=6/8

i=3/4

Therefore, the equation has only one real solution which is i=3/4

Answer:

the answer is a

Step-by-step explanation:

formula= (angle / 360) x π x (diameter / 2)^2

i this case we have the radius already so

= (240/360)*(pi)*(11)^2

=2/3(3.14)*(121)

= around 253.29

= which leads me to believe a is correct

Answer:

Solution given;

angle =240°

radius [r]=11cm

we have

length of arc =240°/360°×π*r²

=240°/360°×2×3.14*11²=253.29cm²

length of the arc is 253.29cm².

The number of 10 bouquets sold should you expect to be lily bouquets will be 5.

A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other.

Given that a florist sold 16 flower bouquets yesterday, including 8 lily bouquets. Based on past data. The number of bouquets sold is 10.

The number of the Lily bouquets will be calculated as:-

Number = ( 8 / 16 ) x 10

Answer:

1.

Step-by-step explanation:

The mean score is (8+6+9+9+8+8)/ 6

= 48/8

= 8.

Deviations from the mean are 0 , -2, 1, 1, 0, 0

Squares of these deviations  are 0, 4, 1, 1, 0, 0

So the variance =  (0 + 4 + 1 + 1 + 0 + 0)/ 6 =  1

Standard deviation = √1 = 1.
