If the pattern rule is defined by the equation `t = 6n`, where `t` is the term value and `n` is the term number, what is the one
blagie [28]

Answer:

600

Step-by-step explanation:

Given

equation t = 6n

n is term number

we have to find 100th term.

Thus, term number is 100

substituting 100 in place of n in equation t=6n , we can find the value of 100th term

t = 6*100 = 600

Thus, 100th term is 600.

The dimensions of a rectangle can be given by x+7 and x+2. If the area of the rectangle is 66 square inches, what are the dimens
Nadusha1986 [10]

to solve  for the dimensions (x+7)(x+2)=66,

we can first use the foiling method to simplify the left side.

x^2 + 2x + 7x + 14 = 66

x^2 + 9x + 14 = 66

now, subtract 66 from both sides.

x^2 + 9x - 52 = 0

now, split this into two parentheses.

(x + 13)(x - 4)

since the root of -13 would give you negative values, x=4. This means that the dimensions of the rectangle are 11 and 6.

Elisondra is eating at a restraurant with three friends. They want to choose at random who will order first. If you model the si
trapecia [35]

An equal-sized spinner is used to model probabilities

The spinner should have 4 equal sections

The number of friends is given as:

\mathbf{Friends = 3}

When Elisondra is included, the total number of people that went to the restaurant is:

\mathbf{n = Friends + 1}

Substitute 3 for Friends

\mathbf{n = 3 + 1}

Add 3 and 1

\mathbf{n = 4}

The number of people that went to the restaurant is the number of equal sections of the spinner.

Hence, the spinner should have 4 equal sections
