Answer:

2530

Step-by-step explanation:

First Round each number to the nearest 10s

503 into 500

472 into 470

499 into 500

539 into 540

522 into 520

then add the numbers we made

500+470+500+540+520=2530

the real answer is 2535 so its close

B. 6.3 Because, for a triangle, you can use the angles to figure out the length. You can also tell that it can’t be D or A because it’s not longer than the base and it’s not small enough to be C.

Explain how you can tell whether the sum of two integers is positive or negative, before adding them.

julsineya [31]

Answer:

The sum of any integer and its opposite is equal to zero. adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Upon descent, an airplane is 20,000 feet above the ground. The air traffic control tower is 200 feet tall. It is determined that

PIT_PIT [208]

Answer:

Base length of plane from control tower = 73,880 feet (Approx.)

Step-by-step explanation:

Given:

Height of plane from ground = 20,000 feet

Height of control tower = 200 feet

Angle of elevation from control tower = 15°

Find:

Base length of plane from control tower

Computation:

Height of plane from control tower = 20,000 - 200

Height of plane from control tower = 19,800 feet

Tan θ = Perpendicular / Base

Tan15 = 19,800 / Base length of plane from control tower

0.268 = 19,800 / Base length of plane from control tower

Base length of plane from control tower = 73,880 feet (Approx.)

Answer:

a- 32,52

b-20+32=52

Step-by-step explanation:

I think there is only one 4

as following 4,8,12,20

4+8=12

8+12=20

20+12=32

20+32=52

52+32=84

84+52=136

136+84=220

136+220=356

so 4,8,12,20,32,52,84,136,220,356
