A commercial jet has been instructed to climb from its present altitude of 9000 feet to a cruising altitude of 57000 feet. If the plane ascends at a rate of 4000 ft/min, how long will it take to reach its cruising altitude

Answer:

1.875 hours

Step-by-step explanation:

easier way

2 miles in 3/4 hours

so

2 miles / .75 hours = 5 miles / x hours

solve for x

(5*.75)/2 = x

x=1.875

or

harder way

you could turn hours into minutes

2 miles in 45 mins

so

2 miles / 45 mins = 5 miles / x mins

solve for x

(5*45)/2 = x

x= 112.5 mins

but they want answer in hours so turn mins into hours by diving by 60

112.5/60 = 1.875 hours

Answer:

9/8ft^3

Step-by-step explanation:

The volume of the box can be found as

V=hwl

where h is height, l is length and w is width of the box

From the picture we have that:

l=6*1/4=6/4=3/2

w=3*1/4=3/4

h=4*1/4=1

Now we can caluclate volume as

V=3/2*3/4*1=9/8ft^3

Answer:

1800 dollars

Step-by-step explanation:

We can set up an equation here to represent the exponential growth in Terry's bank account.

[tex]y = 1600(1.04)^x[/tex]

We can plug in 3 for x since x is the # of years the account is receiving compound interest on.

[tex]y = 1600(1.04)^3[/tex]

[tex]1.04^3 = 1.124864\\1.124864*1600= 1800[/tex]

Answer:

  1.8 mL

Step-by-step explanation:

The amount you need will be the dose divided by the concentration.

  (0.7 g)/(0.400 g/mL) = 7/4 mL = 1.75 mL ≈ 1.8 mL

The dosage will be about 1.8 mL.

Answer:

  shaded area = x^2 -3x +36

Step-by-step explanation:

The area of the shaded region is the overall area less the area of the unshaded enclosed rectangle. The area of a rectangle is the product of its length and width, so the shaded area is ...

  shaded area = (x +1)(x +1) -(x -7)(5)

  = (x^2 +2x +1) -(5x -35)

  = x^2 +2x +1 -5x +35

  shaded area = x^2 -3x +36

Additional comment

You can find the product of two binomials using the distributive property:

  (x +1)(x +1) = x(x +1) +1(x +1)

  = (x^2 +x) +(x +1) = x^2 +2x +1

__

Or, in this case, you can take advantage of the form for the square of a binomial:

  (x +a)^2 = x^2 +2ax +a^2

For a=1, this is ...

  x^2 +2x +1

Step-by-step explanation:

the pattern 7,11,2,18,-7,? is a repeating pattern but at the end the number is changed to -7 so if you go and check the Identity, if the order of number given is ascending ( smaller to larger number) or descending ( larger to smaller number), Calculate the differences between those that are next to each other. Estimate the difference between numbers to calculate the missing number.

A sequence is a list of things in which repeats are permitted and order is important. The last term of the missing pattern is 57.

A sequence is a list of things in which repeats are permitted and order is important. It has members, just like a set. The length of the sequence is defined by the number of items.

In the given sequence, the difference between the first two-term is 4, while in the next two-term is 16(4²), Therefore, in the next two-term, the difference between the two terms will be equal to 64(4³).

Therefore, the last term will be,

[tex]x-(-7)=64\\\\x+7=64\\\\x=64-7\\\\x=57[/tex]

Hence, the last term of the missing pattern is 57.

Answer:

697.5 ft

Step-by-step explanation:

by the concept of equal alternate angels across a traversal, the angle near the car will be 36°

tan 36° = x/90

x= tan 36 * 90 = 697.5 ft

Step-by-step explanation:

the distributing ratio is 2:5.

that means for every 2 white marbles there must be 5 blue marbles.

so, we are taking about "groups" or multiples of 7 (2+5 = 7).

now, even 7×7 = 49 is too small.

but the next multiple of 7 (7×8 = 56) is now big enough to include at least 50 marbles.

so, in order to keep the 2:5 ratio strictly in place, the minimum number of marbles in the bag is 56.
