How Can associative Property be used to mentally find 48+82?

Answers

Answer 1

Answer: Associative property of addition represents this equation:
a + b = b + a
So, how would it be helpful with this given equation?
=> 48 + 82
=> Let's start with the ones place value.
(2 + 8) = 10, bring down 0, carry 1 then ( 4 + 8) = 12 + 1 = 13
So the answer is 130.
If we are going to do it vice versa, still expect that the same answer will occur.

Graham and Hunter are circus performers. A cable lifts Graham into the air at a constant speed of 1.5 ft/s. When Graham’s arms are 18 ft above the ground, Hunter, who is standing directly underneath Graham, throws Graham a ball as the cable continues to lift him higher. Hunter throws the ball from a position 5 ft above the ground with an initial velocity of 24 ft/s. Which system of equations can be used to model this situation?

Answers

The answer to the question above as to which system of equations can be used to model the situation of Graham and Hunter when a cable lifts Graham into the air at a speed of 1.5 ft/s and Hunter throws the ball from a position of 5 ft. above the ground with an initial velocity of 24 ft/s. the equation will be : H = 18t + 1.5t - 16t ^ 2
H = 5 + 24t - 16t ^ 2

The equation of Graham cable is h(t) = -16t² + 1.5t + 18 while The equation of Hunter ball is h(t) = -16t² + 24t + 5

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

The height of a projectile at time t is:

h(t) = -16t² + ut + h'

Where u is the initial velocity and h' is the initial height.

The equation of Graham cable is:

h(t) = -16t² + 1.5t + 18

The equation of Hunter ball is:

h(t) = -16t² + 24t + 5

• Buyers are charged a shipping fee of $4.75 for each scarf order.Which expression can you use to find the total price of a scarf order?
48s - 4.75
4.758 - 48
48s + 4.75
4.75s + 48
HELP NOW PLSSS I BEG YOU

Answers

Answer: 48s + 4.75

Step-by-step explanation:

Each scarf is sold for $48 which is why the total price of buying s scarves is 48s or 48*s.

Assuming a single order of scarves can contain more than one scarf then that means that for s scarves, the shipping fee will remain the same at $4.75.

Should this be the case then the expression for an order of scarves will be;

= 48s + 4.75

This shows the price of ordering s number of scarves plus the shipping cost of $4.75 for the order comprising s number of scarves.

Answer:

48s + 4.75

Express
$2 ^( - 7)$
using a positive exponent.

Answers

Answer:

$(1)/(2^7)$

Step-by-step explanation:

To express the number 2⁻⁷ with a positive exponent, we'll make use of the properties of exponents and their relationship with reciprocals.

$\hrulefill$

Here's a list of the exponent properties:

$\boxed{\left\begin{array}{ccc}\text{\underline{Properties of Exponents:}}\n\n1.\ a^0=1\n\n2.\ a^m * a^n=a^(m+n)\n\n3.\ a^m / a^n \ ((a^m)/(a^n) )=a^(m-n)\n\n4.\ (ab)^m=a^mb^m\n\n5.\ (a/b)^m=a^m/b^m\n\n6.\ (a^m)^n=a^(mn)\n\n7.\ a^(-m)=1/a^m\n\n8.\ a^(m/n)=(\sqrt[n]{a} )^m\end{array}\right}$

In our case, we will use the reciprocal identity (#7 on the table above).

$a^(-m)=(1)/(a^m) \n\n\n\n\therefore 2^(-7)=\boxed{(1)/(2^7) }$

Thus, we can represent 2⁻⁷ as a positive exponent .
