A hardback book cost $7.00 more than a paperback book. Write an expression for the total cost of 1 paperback book and 3 hardback books
Answer:
Tc=3x+(x-7)
Step-by-step explanation: So, the Tc stands for total cost. The x stands for the variable for the hardback books and the x-7 is the price of the paperback book. You could introduce another variable, but that might be more confusing

Answer:
x > -17/6 or x < -1/2
Step-by-step explanation:
4 |3x + 5| + 20 > 6
4 |3x + 5| > -14
|3x + 5| > -14/4
This is where the two equations split.
+:
3x + 5 > -14/4
3x > -17/4
x > -17/6
-:
- (3x + 5) > -14/4
3x + 5 < 14/4
3x < -3/2
x < -1/2

Suppose that 90% of all dialysis patients will survive for at least 5 years. In a simple random sample of 100 new dialysis patients, what is the probability that the proportion surviving for at least five years will exceed 80%, rounded to 5 decimal places
Answer:
The probability [tex]P(\^ p > 0.80) = 0.99957[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.90
The sample size is n = 30
Generally mean of the sampling distribution is [tex]\mu_{\= x } = p = 0.90[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{\frac{p( -p )}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.90( 1 -0.90 )}{100} }[/tex]
=> [tex]\sigma = 0.03[/tex]
Generally the he probability that the proportion surviving for at least five years will exceed 80%, rounded to 5 decimal places is mathematically represented as
[tex]P(\^ p > 0.80) = P(\frac{ \^ p - p }{ \sigma } > \frac{0.80 - 0.90}{0.03} )[/tex]
Generally [tex]\frac{\^p - p}{\sigma} = Z(The standardized \ value \ of \^ p)[/tex]
So
[tex]P(\^ p > 0.80) = P(Z > -3.33 )[/tex]
From the z-table [tex]P(Z > -3.33 ) = 0.99957[/tex]
So
[tex]P(\^ p > 0.80) = 0.99957[/tex]
What is the only real number which, when divided by itself, is 2020
times itself?
Answer:
1/2020
Step-by-step explanation:
We can set up an equation, where x is the number that, when divided by itself, is 2020 times itself:
x/x = 2020*x
The left-hand side reduces to 1:
1 = 2020*x
Now, you can divide both sides by 2020:
x = 1/2020
To check, we can divide 1/2020 by itself:
[tex]\frac{\frac{1}{2020}} {\frac{1}{2020}} = \frac{1}{2020}\cdot \frac{2020}{1} = \frac{2020}{2020} = 1[/tex]
1 is indeed 2020 times 1/2020.
We have that
x=4.95*10^{-4}
From the question we are told
What is the only real number which, when divided by itself, is 2020
times itself
Generally the equation for the statement is mathematically given as
[tex]\frac{x}{x}=2020*x\\\\1=2020*x\\\\x=\frac{1}{2020}\\\\x=4.95*10^{-4}[/tex]
Hence
the only real number which, when divided by itself, is 2020
times itself is
[tex]x=4.95*10^{-4}[/tex]

Answer:
C. Angle MNP
Step-by-step explanation:
Check the corresponding equal sides with congruent angles
Answer: Third choice. [tex]\angle MNP[/tex]
=======================================================
Explanation:
We want to find something congruent to angle ABC.
With angle ABC, we have
A firstB secondC thirdThe order is important.
Looking at the triangle on the right, we see that
angle A has three arc marksangle B has one arc markangle C has two arc marksThe sequence of arc markings can be written as 3,1,2
Now focus your attention on the triangle on the left. Start with the triple arc angle, move to the single arc angle, then go to the double arc angle. You should trace out M, N then P in that exact order.
Therefore [tex]\angle ABC \cong \angle MNP[/tex]
Note how M is first, N is second, then P is third.
This lets us form these pairs of congruences
A = M (first letters; triple arc marking)B = N (second letters; single arc marking)C = P (third letters; double arc marking)Select all polynomials that are divisible by (x-1)(x−1)left parenthesis, x, minus, 1, right parenthesis. Choose all answers that apply: Choose all answers that apply: (Choice A) A A(x)=3x^3+2x^2-xA(x)=3x 3 +2x 2 −xA, left parenthesis, x, right parenthesis, equals, 3, x, cubed, plus, 2, x, squared, minus, x (Choice B) B B(x)=5x^3-4x^2-xB(x)=5x 3 −4x 2 −xB, left parenthesis, x, right parenthesis, equals, 5, x, cubed, minus, 4, x, squared, minus, x (Choice C) C C(x)=2x^3-3x^2+2x-1C(x)=2x 3 −3x 2 +2x−1C, left parenthesis, x, right parenthesis, equals, 2, x, cubed, minus, 3, x, squared, plus, 2, x, minus, 1 (Choice D) D D(x)=x^3+2x^2+3x+2D(x)=x 3 +2x 2 +3x+2
Answer:
Step-by-step explanation:
For us to be able to determine the polynomials that are divisible by (x-1), this means that x-1 must be a factor for the functon to be able to divide any of the polynimial.
Since x-1 is a factor, we can get the value of x
x-1 = 0
x =0+1
x = 1
Next is for to substitute x - 1 into the polynomial and see the ones that will give us zero
For A(x)=3x^3+2x^2-x
A(1) = 3(1)^3+2(1)^2-(1)
A(1) = 3+2-(1)
A(1) = 5-1
A(1) = 4
Since A(1) ≠ 0, then x-1 is not divisible by the polynomial function.
For B(x)=5x^3-4x^2-x
B(1)=5(1)^3-4(1)^2-1
B(1)=5-4-1
B(1)=1-1 = 0
Since B(1) = 0, hence x-1 is divisible by 5x^3-4x^2-x
For the polynomial C(x)= 2x^3-3x^2+2x-1
C(1)=2(1)^3-3(1)^2+2(1)-1
C(1)=2-3+2-1
C(1)= -1+1
C(1)= 0
Since C(1) = 0, hence x-1 is divisible by the
For the polynomial D(x)=x^3+2x^2+3x+2
D(1)=1^3+2(1)^2+3(1)+2
D(1)=1+2+3+2
D(x) = 8
Hence the polynomial D(x) is not divisible by x-1
Hence the correct options are B(x)=5x^3-4x^2-x and 2x^3-3x^2+2x-1

The length of the rectangle is four times it’s width. The rectangle has an area of 1024cm2. What is the width of the rectangle
Answer:
Length = 4 times width
Area = length * width

=4w²
So 4w²=1024 cm² (given)
w²=1024/4=256
w=√(256 cm²)

Answer:
C) √3
Step-by-step explanation:
Treating this as a geometry problem, not a fluid dynamics problem, we assume the area of the smaller vessels must total that of the larger one. Then the ratio of areas of the smaller vessels to the larger one is 1/3. The ratio of radii is the square root of that: 1/√3.
Then the radius of the smaller arteries must be ...
(3 mm)(1/√3) = √3 mm
