When we are rounding a number to the nearest hundred we need to check the tens. If the tens algarism is greater or equal to 5, then we round up and if it is lower than that we round down.

Delta operates a fleet of 764 aircrafts. The tens on this number is the algarism "6", therefore we should round up. Delta operates approximately 800 aircrafts.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
professor190 [17]

Answer:

25

Step-by-step explanation:

The formula for the Pythagorean Theorem is:

\sqrt{a^2+b^2}=c

Now,

A=7

B=24

7x7=49

24x24=576

Add,

576+49=625

Last,

Take the square root of 625

The square root of 625 is 25

c=25

To Check if the hypotenuse is correct:

a^2+b^2=c^2

7^2+24^2=25^2

7x7=49

24x24=576

25x25=625

49+576=625

625=625,

Therefore the hypotenuse is 25.

fiona draws a 24 centimeter rectangle.gregory draws a 24 square inch rectangle.whose rectangle is in area .how do you know
Valentin [98]

Answer:

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

Step-by-step explanation:

Given:

Fiona draws a 24 centimeter rectangle.

Gregory draws a 24 square inch rectangle.

To Find:

Whose rectangle is in area = ?

Solution:

Rectangle has a dimension as

Length and Width which are in meters, centimeters, inches, feet, units, etc.

For Area

Area\ of\ Rectangle=Length\times Width

here units are getting Multiplied so it becomes

unit × unit = unit²  = square units

m × m = m² =square meter

inch × inch = inch² =square inches

Hence Area is calculated in square units.

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

Tatiana [17]

Answer:

Step-by-step explanation:

1. Area => 7.5 x 2 = 15 m² (Choice B)

2. Area => 5 x 11 = 55 in² (Choice B)

3. Area = (12 x 18) * 0.5 = 108 cm² (Choice A)

4. Triangular Pyramid (Choice D)

6. Area of Rectangle => 12 x 9 = 108

   Area of Triangle => 7x6 = 42

   Sum of Area => 150

7.  Surface Area => (4x4)x6 = 96 in² (Choice D)

8. Volume = 3x15x14 = 630 in³ (Choice D)

Write the equation of the parabola in vertex form.
stellarik [79]

well, looking at the picture of this vertically opening parabola, it has a vertex at 0,0 and it passes through 2,1 hmm ok

~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{"a"~is~negative}{op ens~\cap}\qquad \stackrel{"a"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ y = a(x-0)^2+0\qquad \stackrel{\textit{we also know that}}{x=2\qquad y = 1}\qquad \implies 1=a(2-0)^2+0 \\\\\\ 1=4a\implies \cfrac{1}{4}=a~\hspace{10em} \boxed{y=\cfrac{1}{4}x^2}
