Answer:
16
Step-by-step explanation:
There are several ways to go at this. Perhaps the simplest is to put the expression into your calculator.
__
Using the rules of exponents, you recognize ...
a^-b = 1/a^b
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
__
So, we can rewrite the expression to be ...
[tex]\displaystyle\frac{1}{2}\cdot\left(\frac{1}{2}\right)^{-5}=2^{-1}\cdot(2^{-1})^-5\\\\=2^{-1}\cdot2^{(-1)(-5)}=2^{-1}\cdot2^5\\\\=2^{-1+5}=2^4=\boxed{16}[/tex]

Answers
Given:
The recipe calls for [tex]\dfrac{3}{8}[/tex] cup of chili powder.
Karl only wants to use half as much so it won’t be so spicy.
To find:
How much chili powder should Karl use?
Solution:
We have,
Chill power for recipe = [tex]\dfrac{3}{8}[/tex] cup
Chill power used by Karl is half of chill power for recipe.
[tex]\text{Chill power used by Karl}=\dfrac{1}{2}\times \dfrac{3}{8}[/tex] cup[tex]\text{Chill power used by Karl}=\dfrac{3}{16}[/tex] cup
Therefore, [tex]\dfrac{3}{16}[/tex] cup of chili powder should Karl use.

15. Ethan planted sunflowers in different types of soil and measured their growth each week.
Plant 1 started at a height of 10 inches and grew 10 inches per week. Plant 2 started at a
height of 18 inches and grew 8 inches per week. Ethan wants to predict the number of weeks
it will take for the plants to reach the same height.
Ethan concludes that the plants will reach the same height after 50 weeks. Is Ethan correct?
Explain why or why not.
Answers
Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Answer: No he is not correct
Step-by-step explanation:
plant 1 will be taller than plant 2 at 50 weeks
do 50 times 10 = 500in
do 50 times 8 = 400in

Step-by-step explanation:
You are multiplying x² - 4x + 4 and 6x + 3.
This is set up like:
6x + 3(x² - 4x + 4)
To solve this, we want to multiply each term that is outside of the parentheses with each term that is inside of the parentheses.
Let's start with 6x.
6x • x² = 6x³
6x • -4x = -24x²
6x • 4 = 24x
These numbers will be in the first blank row.
Now, let's move onto 3.
3 • x² = 3x²
3 • -4x = -12x
3 • 4 = 12
These numbers will be in the second blank row.
Now let's write all these numbers together.
6x³ - 24x² + 24x + 3x² - 12x + 12
Combine like terms, pay attention to the exponent.
6x³ - 21x² + 12x + 12
Refer to the completed table below.

Answers
Answer:
degree of the polynomial = 7
Number of terms = 2
Name = binomial
leading coefficient = 5
Step-by-step explanation:
The polynomial is x³y² - 5x³yz³
The degree of a polynomial is the highest exponent of any of its variables.
But in this case where we have two variable together, we sum up their exponents and the Hughes one will be the degree of the polynomial.
Thus;
x³y² has a degree of 3 + 2 = 5
5x³yz³ has a degree of 3 + 1 + 3 = 7
Thus,7 is the highest and the degree of the polynomial is 7.
There are two terms which are x³y² and 5x³yz³
Since it has two terms, it is a binomial.
To get the coefficient, I will rearrange in descending order of degree;
-5x³yz³ + x³y²
Thus, leading coefficient = 5
Please answer both A. and B.

(a) ΔABC and ΔEDC are similar because all the angles in ΔABC is equal to the corresponding angles in ΔEDC.
I.e, ΔABC is equiangular to ΔEDC. (AAA).
(b) From the diagram.
for similar angle, ratio of corresponding sides are equal
100/d = 4x/7x
100/d = 4/7
where d = distance across the river
solve for d

The volume of the cylinder is 225(pi) cm³. What is the height of
the cylinder?
(A) 6.25 cm
(B) 25 cm
(C) 37.5 cm
(D) 75 cm
Answers
Answer:
it's 25 cm
Step-by-step explanation:
Volume = 225π
or πr²h= 225π
or r²h= 225
or h= 225/r²
here diameter d = 6cm so radius r=d/2 = 3cm
or h= 225/3²
hence h= 25cm

A box contains 3 pens, 2 markers, and 1 highlighter. Tara selects one item at random and does not return it to the box. She then selects a second item at random. What is the probability that Tara selects 1 pen and then 1 marker?
Answers
Answer:
1/5
Step-by-step explanation:
There are a total of 6 items in the beginning. In the first selection, there is a 3/6 chance that she selects a pen. Since she does not return it to the box, there are 5 items left. The possibility to select a marker is 2/5. Simply multiply the two fractions. You will get 1/5.
