Answer:

(5^2)(n^4)

Step-by-step explanation:

since the exponents have common bases of 5, we can think of it like 4-2, since the 5^2 being in the denominator makes it negative, and since n^4 is left unaffected, we are left over with (5^2)(n^4)

I feel like typing words to explain it would make you confused so instead I took an screenshot of step by step on how to do it and the answer to you’re question.

Answer:

$x=42.9\ m$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two figures are similar, the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles MNP and MAB are similar by AA Similarity Theorem

$\frac{MA}{MN}=\frac{MB}{MP}$

we have

$MA=MN-AN=67.2-32=35.2\ m$

$MN=67.2\ m$

$MB=x\ m$

$MP=81.9\ m$

substitute the given values

$\frac{35.2}{67.2}=\frac{x}{81.9}$

Solve for x

$x=\frac{35.2}{67.2}(81.9)\\\\x=42.9\ m$

A retail shop is replacing their flooring with laminate wood. The floor plan is shown below. Determine the total square feet of

Phantasy [73]

<h3>Answer: 1075 square feet</h3>

===========================================================

Explanation:

As shown in the diagram below, I've drawn a blue horizontal line to split the figure into two rectangles (smaller one up top, larger down below).

The smaller rectangle up top is 25 ft by 8 ft, giving an area of 25*8 = 200 sq ft.

The larger rectangle down below is 35 ft by 25 ft so we have an area of 35*25 = 875 sq ft.

The total area is 200+875 = 1075 square feet

Notes:

We can write "square feet" as "sq ft" or as "ft^2" without quotes.
The portion "5 ft", in the upper left corner, is never used.

basically logarithms are like reverse exponents

log7, 49 is basically asking 7 to the what gets you 49

because of that its 2 because 7^2 gets you 49

alisha [4.7K]

Let the larger number be w and the smaller number be k;
5w-11=3k
3k+16=4w
Reorganizing the equations;
5w-3k=11
4w-3k=16
Subtracting equation 2 from equation 1:
w=-5
Replacing value of w in equation 1;
5(-5)-11=3k
-25-11=3k
3k=-36
k=-12
The numbers are -5 and -12
