Tarzan played a game in which he could either lose or gain points
each round. At the end of 3 rounds, he had -8 points. After one more
round, he had 12 points. Express the change in points in the most
recent round as an integer.
Answer:
20
Step-by-step explanation:
|-8 - 12| = 20
The absolute value of -8 minus 12 will show us the difference, or the change in points as in this problem
|-8 - 12| = 20

The scale on a blueprint says that 1 cm is the equivalent of 3 ft. A particular line on the blueprint representing a wall measures 12 cm. How long should the wall be?
The scale on a blueprint says that 1 cm is the equivalent of 3 ft. A particular line on the blueprint representing a wall measures 12 cm. Wall is 36 ft long.
Given,
Scale on a blueprint says that 1 cm is the equivalent of 3 ft
1cm = 3ft
A particular line on the blueprint representing a wall measures 12 cm.
12cm = 12(3) ft
= 36ft
Wall is 36 ft long.
The act or system of measuring is referred to as measurement. It may be viewed as a procedure for utilizing numbers to define physical objects. "This rod is bigger than that rod," for instance.
Since we don't know anything about the specific characteristics of the provided rods, this statement only serves a very narrow function of comparison. However, if we claim that the first rod is 20 inches long and the second is 15 inches, the first rod will be 5 inches longer than the second. This claim provides us with support for our deduction and makes greater sense mathematically.

The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by

Find the average rate of change of h over the interval

( ) feet per second
Interpret your result.
During the last three seconds of the objects's time in the air, it is
falling at an average rate of (. )feet per second.
The average rate of change of h over the interval is -48 feet per second.
Given,
The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by
h(t) = −16t2 + 96t, 0 ≤ t ≤ 6.
We need to find the average rate of change of h over the interval [3, 6].
How do we find the average rate of change of a function over an interval?If we have an interval [a, b] and a function f(x).
The rate of change is given by:
= f(b) - f(a) / b - a
We have,
h(t) = −16t² + 96t and [3, 6].
h(6) = -16 x 6² + 96 x 6 = -576 + 576 = 0
h(3) = -16 x 3² + 96 x 3 = -144 + 288 = 144
The average rate of change of h is:
= h(6) - h(3) / 6 - 3
= 0 - 144 / 3
= -144 / 3
= -48
Thus the average rate of change of h over the interval is -48 feet per second.

Step-by-step explanation:
a normal function expresses y (the functional result) in terms of x (and constants).
we need to transform this to express now x in terms of y (and constants).
at the end we only rename x into y and y into x to make it an actual function.
h(x) = y = (-5x + 6)/(3x + 4)
y(3x + 4) = (-5x + 6)
3xy + 4y = -5x + 6
4y - 6 = -5x - 3xy = x(-5 - 3y)
x = (4y - 6)/(-5 - 3y)
and after renaming we get therefore the function
y = h-1(x) = (4x - 6)/(-3x - 5)

Neil and Yuki run a data entry service. Neil starts at 9:00am and can type 45 words per minute. Yuki arrives at 10:30am and can type 60 words per minute. Write and solve an inequality to find at what time Yuki will have typed more words than Neil. Let x represent the time in minutes.
Answer:
45*90+45*x and Yuki would have typed 60*x.
Words typed by Yuki > Words typed by Neil
45 \times 90 + 45 \times x < 90 \times x45×90+45×x<90×x
Solving above inequality would give
x > 90x>90
it means that 90 minutes after 10:30 AM
Yuki would type more than Neil.

P ( A ) = 0.67 , P(A∪B)=0.89 and ( B ) = 0.54 . Find P(A∪B′) P ( A ∪ B ′ ) . Give an exact answer as a decimal
The value of the probability P(A u B') is 0.8218
How to determine the probability?The given parameters are
P(A) = 0.67
P(B) = 0.54
P(A u B) = 0.89
From the above parameters, we have
P(B') = 1 - P(B)
P(B') = 1 - 0.54
P(B') = 0.46
So, we have
P(A u B') = P(A) + P(B') - [P(A) * P(B')]
This gives
P(A u B') = 0.67 + 0.46 - (0.67 * 0.46)
Evaluate
P(A u B') = 0.8218
Hence, the value of the probability P(A u B') is 0.8218
