1/2(13-5)+(4+8)^2
A. 148
B. 144
C. 20
D. 16
We must follow "PEMDAS" order of operations rules. Anything inside parentheses must be done first, followed by exponentiation, multiplication and division, and finally additionl and subtraction.
1/2(13-5)+(4+8)^2 has three sets of parentheses enclosing mathematical expressions: (1/2), (13 - 5) and (4 + 8). These evaluate to:
1/2, 8, 12
and so we now have (1/2)(8) + (12)^2
Exponentiation is next. We get: (1/2)(8) + 144
Next is multiplication: 4 + 144
Last is addition: 148
Answer A is correct: 148
8 x 9+4^2-(63/7)

Use this graph of velocity vs. time for two objects to answer the question.
Which statement makes an accurate comparison of the motions for objects C and D?
A. Object C has an acceleration that is greater than the acceleration for D.
B. Objects C and D have different velocities but the same acceleration.
C. Object D has an acceleration that is greater than the acceleration for C.
D. Objects C and D have different accelerations but the same velocity throughout the motion.
Answer:
Object C has an acceleration that is greater than the acceleration for D
- I just took the quiz and got 100%
Using derivatives, it is found that the correct option is:
A. Object C has an acceleration that is greater than the acceleration for D.
The acceleration is the derivative of the velocity, given by change in velocity divided by change in time, that is:
[tex]a = \frac{\Delta_v}{\Delta_t}[/tex]
In this problem:
The change in time for objects C and T is the same.The change in velocity for object C is greater, thus, it has a greater acceleration, and the correct option is:A. Object C has an acceleration that is greater than the acceleration for D.

We make both number is same units.
Since, we know that;
1 feet = 12 inches
Hence,
The ratio become 30 inches to 12 inches.
Now, Solve in simplest form of the ratio 30 inches to 12 inches.
⇒ 30 inches to 12 inches
⇒ 30 : 12
⇒ 30 / 12
Divide in numerator and denominator by 2;
⇒ 15 / 6
Divide in numerator and denominator by 3;
⇒ 5 / 2
Thus, The simplest form of the ratio of 30 : 12 is = 5 : 2
Therefore,

Consider the line y = -6x + 9
Find the equation of the line that is perpendicular to this line and passes through the point (3, 6)
Find the equation of the line that is parallel to this line and passes through the point (3,6)
Answer:
6x - y -12=0
Step-by-step explanation:
Given line ,
=> y = -6x + 9
On comparing to the slope intercept form ,
m = -6The slope of the perpendicular line will be negative reciprocal of its slope , say m'
m' = 1/6The given point is (3,6) . On using point Slope form of the line we have ,
=> x - 3 = 1/6 ( y - 6)
=> x - 3 = y/6 - 1
=> x -2 = y/6
=> 6x - 12 = y
=> 6x - y -12 = 0

Need help pre college
Answer:
y = -2x + 12
Step-by-step explanation:
Use the slope intercept equation y=mx+c
Now, c is unknown so substitute all known information to calculate it
That is, 2=-2(5)+c
Solving that we get, c=12
We already know m=-2
Substituting m and c into the slope intercept equation we find that the answer is, y= -2x+12

how can you use act it out to show the related addition facts? use the math word addend and sum in your answer . 6+2=8 2+6=8
Answer:
6+3=9 3+6=9 are sum other sum are
4+3=7 3+4=7
5+4=9 4+5=9
Acting out scenarios with objects like apples can visually demonstrate the commutative property of addition for related facts like 6+2=8 and 2+6=8.
⇒ For 6+2=8; Imagine you have 6 apples, and a friend gives you 2 more apples. Physically place 6 apples in one pile, then add 2 more apples to the pile. Count all the apples together to reach 8.
⇒ For 2+6=8; Similarly, start with 2 apples and then have your friend give you 6 apples. Place the 2 apples in one pile and then add 6 more apples. Count all the apples together to again reach 8.
By acting out these scenarios with physical objects like apples, we are visually representing the addition facts. This helps to understand concept that addition is commutative, meaning the order of the numbers doesn't affect the sum.

Step-by-step explanation:
Triangle PQR and triangle STR are congruent and that makes |PR| and |SR| equal in measure:
2x + 6 = 4x export like terms to same side
6 = 4x - 2x subtract
6 = 2x divide both sides by 2
