You are given Maggie's planning on going to Penn State University. You are also given that she could live there if she has more than $2,000 if she already bought a laptop at $450.

For part A, the inequality that we can form is x ≥ 2,450 because she needs more than $2,000 to survive after buying a $450 dollar worth laptop. Adding the two makes it 2,450.

For part B, if she has to withdraw $30 per week, then the inequality that we can form is x ≥ 2,450 - 30

For part C,
30x ≥ 2,000
x ≥ 66.67

For part D, the answer 66.67 means that Maggie can have 66 times to withdraw $30 per week worth of food from her balance $2000.

I climb half the steps in a staircase. Next, I climb one-third of the remaining steps. Then I climb one-eight of the rest and st

Given parameters:

First sets of staircase = $\frac{1}{2}$

Next sets = $\frac{1}{3}$

Third sets = $\frac{1}{8}$

Unknown:

The least possible number of steps =?

Solution:

The least possible number of steps will be the lowest common multiples of these sets of steps.

We want fractions that will give whole numbers because realistically, one cannot take half a step of a step.

So, the number of steps must be a multiple of denominators of the fractions given.

Denominators are 2 , 3 and 8

Their least common multiple is 24;

This the lowest number by which 2, 3 and 8 can all divide.

So, the least number is 24 steps

Suppose for some positive real number aa that (a^(1 /4) ⋅ a ^(1/ 2 )⋅ a ^(1/ 4) 2 = 3.

Grace [21]

Answer:

(a) $a=\frac{3}{2}$

(b) We use the property of exponent that when there is multiplication of two function then there exponent are added

Step-by-step explanation:

We have given expression

$(a^{\frac{1}{4}}a^{\frac{1}{2}}a^{\frac{1}{4}})2=3$

(a) We have to find the value of a

We know the property of exponent that when there is multiplication of two function then there is addition of exponent

So $a^{\frac{1}{4}+\frac{1}{2}+\frac{1}{4}}\times 2=3$

$2a=3$

$a=\frac{3}{2}$

(b) We use the property of exponent that when there is multiplication of two function then there exponent are added

2^4⋅2^5−(2^2)^2<br><br> PLEASE HELP FAST!

Dvinal [7]

2^9 - 2^4 = 496

when you multiply exponents, you just add the two (4 and 5) and keep the coefficient the same.

when you multiply by an exponent (^2), you multiple the exponents and keep the coefficient the same.

Answer:

(x, y) = (0, -26)

Step-by-step explanation:

The y-intercept is the y-value that corresponds to x=0. Here, we have a table that has x-values that differ by 12 and 24. We want to find the y-value that corresponds to an x-value 24 less than the lowest one on the table:

24 -24 = 0

We notice that when x-values differ by 24, the y-values differ by 10 -(-8) = 18. So, the y-value we want is 18 less than the lowest one in the table:

y = -8 -18 = -26

The (x, y) coordinates of the y-intercept are (0, -26).
