Answer:
Aiden can buy 2 gel pens after buying the calculator.
Answer:
<6, <5, <7 all equal 48 degrees.
<1, <2, <3, <4 all equal 132 degrees.
Step-by-step explanation:
Straight angles (like <5 & <2) are supplementary, so they equal 180 when added together
Vertical angles (like <2 & <1) have the same measurments
Corresponding angles (like <8 & <6) have the same measurements
Alternate interior angles (like <8 & <5) have the same measurments
Alternate exterior angles (like <6 & <7) have the same measurements
Same-side interior angles (like <8 & <2) are supplementary, so they add to 180.
There's more, and there's other ways to do this, this is just an example. Good luck! <3
Answer:
Step-by-step explanation:
The velocity of the arrow when it was launched upwards is 320 feet per second. The height of the platform from which it was launched is 50 ft
This means that the arrow is already 50 feets from the ground before moving upwards.
The height that it attains on moving from 50 feets will be determined by Newton's formula of motion.
v^2 = u^2 + 2as
u = initial velocity = 320 feet per second.
1 feet per second = 0.305 meters per second
320 feet per second = 320× 0.305
= 97.6 feets per second
a = acceleration due to gravity =
- 32.17405 feet/second^2 because the arrow is moving upwards)
s =maximum height of the arrow
v = final velocity = 0 feet/second
Substituting into the equation,
0^2 = 97.6^2 + 2×- 32.17405 × s
0 = 9525.76 - 64.3481s
64.3481s = 9525.76
s = 9525.76/64.3481 = 148.03 feets
Total height from the ground would be
148.03 + 50 = 198.03 feets
Answer:
Absolute value is the distance from numbers on a number line. The absolute value of -7 is 7 b/c it is 7 units from 0. The absolute value of 5 is 5 b/c it is 5 units from 0.
A negative number is a number that is negative. On a horizontal number line negative numbers are to the left.
A positive number is a number that is positive. On a horizontal number line positive numbers are to the right.
I don't understand the last paragraph though. Hope this helped :D
