The length of a rectangular deck is 4 times its width. If the deck's perimeter is 30 feet what is the deck's area???
Answer:
36 sq ft
Step-by-step explanation:
The answer fam is 36 feet^2
Let width be x
Then, length be 4x
Perimeter=2(l+b)
30=2(4x+x)
30=2×5x
30=10x
x=3feet
Length=4×3=12 feet
Width=3 feet
Area=lb
=12×3=36 feet^2

Answer:
[tex]\frac{16}{x} = \frac{80}{100}[/tex]
Step-by-step explanation:
To set up this proportion, we know that 16 must correspond with 80% and the x, the number we're looking for must correspond with 100%
[tex]\frac{16}{x} = \frac{80}{100}[/tex]
This would be the correct proportion, and you could simplify it to equal
[tex]\frac{16*100}{80}[/tex]
a plumber charges $25 per hour on weekdays and $40 per hour on weekends. The plumber billed a total of 190 hours, worth a total of $5275. Let x represent the number of weekend hours worked, and write algebraic expressions for each of parts a-c below
Step-by-step explanation:
if x is the amount of weekend hours, let y be the amount of weekday hours. then you can solve for x by using the equations x + y = 190 and 49x + 25y = 5275. once you have values for x and y, the other answers should be easy

How are x and y intercepts alike and different? ( I need like 3 reasons for each)
Answer:
x and y intercepts are alike because they're both on the graph ,they help you graph a line, they can be both found in the slope-intercept form equation
they're different one is when it can be found where it crosses the X line and one can be found where it's the y line, when is found at the end of the equation for slope intercept form and what is found near the slope. x-intercept is an input and y-intercept is an output

Answer: It’s A
Step-by-step explanation: C= -14/3 which is simplified to -4 2/3
Answer:
A.
Step-by-step explanation:
So you foil 2c and -5
Which will give you 5c+4=2c-10
Subtract 2c 5c-2c+4=2c-2c-10
Then You will get3c+4=−10
Step 3: Subtract 4 from both sides.
3c+4−4=−10−4
3c=−14
Step 4: Divide both sides by 3.
3c/3=-14/3
So it will be -14/3 which is -42/3
Which is A.
Example 3.7.4: The sum of two positive numbers is 16. What is the smallest possible value of the sum of their squares
Answer:
The smallest possible value of the sum of their squares is 128.
Step-by-step explanation:
Let the first number = x
let the the second number = y
x + y = 16
y = 16 -x
minimum value, f = x² + y²
f(x) = x² + (16-x)²
f(x) = x² + 256 - 32x + x²
f(x) = 2x² - 32x + 256
f(x)' = 4x - 32
4x - 32 = 0
4x = 32
x = 32 / 4
x = 8
The absolute minimum value of x = 8
y = 16 - x
y = 8
The smallest possible value of the sum of their squares is given by x² + y²;
= (8)² + (8)²
= 128
Therefore, the smallest possible value of the sum of their squares is 128.
Find the sum of the first 36 terms of the following series, to the nearest integer.
2, 5,8,...
The sequence 2,5,8,..... The sum of the 1st 36 terms in arithmetic sequence is 1962.
Given that,
The sequence 2,5,8,.....
We have to find the sum of the 1st 36 terms of the sequence.
We have an sum of the sequence formula from arithmetic sequence.
The sum of all the digits in an arithmetic sequence is determined using the sum of the arithmetic sequence formula. Remember that the addition of the members is the definition of a finite arithmetic sequence. The typical order of the arithmetic sequence is (a, a + d, a + 2d,...), with "a" standing for the first term and "d" for the common difference.
Sum of the arithmetic sequence is S = n/2 {2a + (n − 1) d}
Where
S is the total of the mathematical sequence,
a is the first term,
d is difference of the terms,
n is number of terms in the sequence.
So, now a =2, n=36,d=5-2=3
S=36/2{ 2×2+(36-1)×3}
S=18{4+(35)×3}
S=18(4+105)
S=18×109
S=1962
Therefore, the sum of the 1st 36 terms in arithmetic sequence is 1962.

Is x − 8 a factor of the function f(x) = −2x3 + 17x2 − 64? Explain. (2 points)
Answer:
x-8 is a factor of f(x)
Step-by-step explanation:
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
We are given the function
[tex]f(x)=-2x^3+17x^2-64[/tex]
And it's required to find if x-8 is a factor of f.
Applying the mentioned theorem, we only have to find f(8):
[tex]f(8)=-2\cdot 8^3+17\cdot 8^2-64[/tex]
Operating:
[tex]f(8)=-2\cdot 512+17\cdot 64-64[/tex]
[tex]f(8)=-1024+1088-64[/tex]
[tex]f(8)=0[/tex]
Thus, x-8 is a factor of f(x)

Miguel has a total of 27 dimes and nickels. The total value of the coins is $1.80. How many dimes and nickels does he have?
Answer:
There are 9 dimes and 18 nickels.
Step-by-step explanation:
Let d = be the number of dimes
n = be the number of nickels
d + n = 27...eq.1
0.10d + 0.05n = 1.80...eq.2
Solve the system of equations
d + n = 27
10d + 5n = 180 ( multiply eq.2 by 100 )
-5d - 5n = -135
5d = 45
d = 9 , there are 9 dimes so,0.90
n = 27 - 9 = 18, there are 18 nickels so, 0.90
To check: 9 dimes + 18 nickels = 27 coins
0.90 + 0.90 = $ 1.80 total value of the coins

When looking at the results of a 99% confidence interval, we can predict what the results of the two-sided significance test will be: Group of answer choices
Answer:
alpha=0.01
Step-by-step explanation:
confidence level = 1 - alpha
so alpha = 1 - confidence level = 1 - 0.99 = 0.01
In statistics, alpha represents the value that checks the test statistic in order to determine if it is significant or not. In other words, alpha is the acceptable margin of type 1 error. Alpha is also called the significance level, which opposes the confidence level. Significance level + confidence level = 1.

Answer:
y = 7x - 47
Step-by-step explanation:
y = mx + b (m is slope, b y-intercept)
Parallel lines have the same slope.
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~~
y = 7x + 1
m = 7
(6, - 5)
y + 5 = 7 (x - 6)
y = 7x - 47
