Answer:
K = 6
Step-by-step explanation:
Plug in what the letter equals to
Equation will look like:
2(11) = 4 + 3k or 3k + 4 = 2(11)
multiple the 2 by 11 and get 22
3k + 4 = 22 subtract the 4 so it can leave the 3k alone
22 - 4 = 18 now divide 3 from k and do it in the other side
18/3 = 6
so K = 6
Express 2 x 2 x 2 x 2 x 2 in index notation.
Given:
The expression is
[tex]2\times 2\times 2\times 2\times 2[/tex]
To find:
The index notation of the given expression.
Solution:
Index: The power of a number and a variable is called its index.
Index notation: The expression which has a base and a power.
In the given expression 2 is multiplied 5 times, so by using the property of exponent we get
[tex]2\times 2\times 2\times 2\times 2=2^{1+1+1+1+1}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]2\times 2\times 2\times 2\times 2=2^{5}[/tex]
Therefore, the index notation of the given expression is [tex]2^5[/tex].

Answer:
x=128
Step-by-step explanation:
180-52=128
Answer: x= 128 degrees
Step-by-step explanation:
Angle “x” and angle with measure of 52 degrees are a linear pair.
Linear pairs sum to 180.
52+x=180. Subtract 52 from both sides.
X= 128
*OR you can use angles around a point sum to 360 degrees.
52+38+142+x = 360. Combine like terms.
232+x= 360. Subtract 232 from both sides.
X= 128

A rectangle has a perimeter of 26 inches. All of its side lengths are doubled to create a new rectangle.
a. How does the perimeter of the new rectangle compare to the perimeter of the original rectangle?
b. How does the area of the new rectangle compare to the area of the original rectangle?
Answer:
a) the new perimeter is 2 times the old perimeter
b) the new area is 4 times the old area
Step-by-step explanation:
b) the doubling of the length and width affects the area formula like this:
old triangle area formula = 1/2bh
new triangle area formula = 1/2(2b)(2h), you see the 2 x 2 causes the area to be 4 fold

If y = x² + 2x + 3, find the value of y when x = -1
Answer:
y = 2
Step-by-step explanation:
Given
y = x² + 2x + 3 ← substitute x = - 1
y = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2
Using your answer from part (b) and inequality symbols, write one statement that shows the relationship among all of the numbers.
Answer:
(b) Least to greatest numbers are -1.0, [tex]-\frac{1}{4}[/tex] , 0, 0.5, 1.5
(c) -1.0 < [tex]-\frac{1}{4}[/tex] < 0 < 0.5 < 1.5
OR
1.5 > 0.5 > 0 > [tex]-\frac{1}{4}[/tex] > -1.0
Step-by-step explanation:
P.S - The exact question is -
Given - Kendra collected data for her science project. She surveyed
people asking them how many hours they sleep during a
typical night.
The chart below shows how each person’s response compares
to 8 hours (which is the answer she expected most people to say).
Name Number of Hours Compared to Hours
(usually slept each night)
Frankie 8.5 0.5
Mr. Fields 7 −1.0
Karla 9.5 1.5
Louis 8 0
Tiffany [tex]7\frac{3}{4}[/tex] [tex]-\frac{1}{4}[/tex]
To find - (a) Plot and label each of the numbers in the right-most column
of the table above on the number line below.
(b) List the numbers from least to greatest.
(c) Using your answer from part (b) and inequality symbols,
write one statement that shows the relationship among all
of the numbers.
Proof -
(a)
We can see that the numbers in the right-most column are 0.5, -1.0, 1.5, 0, [tex]-\frac{1}{4}[/tex]
We can write [tex]-\frac{1}{4}[/tex] = -0.25
Now,
We have to label them in the number line
The number line is as follows :
(b)
Least to greatest numbers are -1.0, [tex]-\frac{1}{4}[/tex] , 0, 0.5, 1.5
(c)
By using inequality symbol, we get
-1.0 < [tex]-\frac{1}{4}[/tex] < 0 < 0.5 < 1.5
OR
1.5 > 0.5 > 0 > [tex]-\frac{1}{4}[/tex] > -1.0
solve for the slope / y-intercept and the equation
Answer:
Slope = -3, Y-intercept = -2, y = -3x -2
Step-by-step explanation:
There are multiple points plotted on the graph, but right now, we only need to focus on two.
(-2, 4) (-1, 1)
Using the ordered pairs, do delta y/ delta x to get the slope
(1-4)/(-1-(-2)
(-3)/(-1+2)
(-3)/(1)
Slope = -3
y = -3x + b
As shown on the graph, the y-intercept is -2. It is when x = 0
So, for the equation, substitute the found values.
y = -3x -2

100% of what number is 27? Provide an exact fraction answer
Answer:
Your answer is 27
I hope I helped, would appreciate brainliest! ;)
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
27% = 27 'out of one hundred',
p% is read p 'percent',
27% = 27/100 = 27 ÷ 100
Calculate percentage:
'Percentage' is obtained by multiplying 100 by 27%
27% of 100 is equivalent to multiplying them:
27% × 100 = ?
27% × 100 =
(27 ÷ 100) × 100 =
(27 × 100) ÷ 100 =
2,700 ÷ 100 =
27
Proof.
How do we check the result?
If 27% × 100 = 27 =>
Divide 27 by 100...
... And see if we get as a result: 27%
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
n/100 = n%, any number.
Calculate the percent value:
27 ÷ 100 =
0.27 =
0.27 × 100/100 =
(0.27 × 100)/100 =
27/100 =
27%
So we have proved that the calculations are correct.
Answer:
Percentage of
27% of 100 = 27
Answer:
27%
Convert fraction (ratio) 27 / 100 Answer: 27%
Sarah got £72 for her birthday. She spent 40% of the money on
clothes and 1/6 of the remaining money on makeup. How much did she
have left over?
Solution: She has £36 remaining.
To solve this is fairly simple. First we multiple 72 by .4 to get 40%. This gives us 28.8.
We then subtract 28.8 by 72 to get the money she has remaining after she spends 40%. The answer to this is 43.2
Then she spends 1/6 on makeup. So we divide 43.2 by 6 and multiply again by 5, which gives us 36.

What is the equation of the line perpendicular to y = 1/4x – 5 through the point (4,3)?
y-yi=m(x-xi)
y-3=1/4(x-4)
y-3=x-4/4
4y-12=x-4
4y+x-12+4=0
4y+x-8=0
so the equation of
the line perpendicular

y=1/4-5 through
the point(4,3)
