Answer:
25 pages.
Step-by-step explanation:
all the other answers seem to be less than 200. 20(10) is 200, but it says more than 200 pages. so that means the only correct answer is 25 pages per day. 25(10) is 250 pages, exceeding 200.

The Linear function m=45-8b represents The amount m (in dollars) money that you have after buying b books. select all the values that are in the domain of function.
Answer:
b = {0, 1, 2, 3, 4, 5}
Step-by-step explanation:
The domain of a function is simply all the possible values the independent variable can assume that the function will work and will give a real number.
In this question, we have:
m = 45 – 8b
b is the independent variable because the money, m, depends on the number of books, b, bought.
Since we can't have negative value for m as it represents an amount of money, then the values b can assume can be gotten through:
45 – 8b = 0,
8b = 45
b = 45/8 = 5.625
For the m, money, to remain positive b shouldn't go beyond 5.625
Also we should note that b, books, can't be a negative (no such thing as negative books) or a fractional value (no such thing as buying parts of a book) as well. Therefore, b = {0, 1, 2, 3, 4, 5}

The cube root of 348 is ~7.03, but the square root of 48 is ~6.9. Making the square root of 48 smaller.
5. You are taking a math quiz and need to complete at least 10 Geometry problems
and Algebra problems within 120 minutes. It will take you 15 minutes for each
Geometry problem and 10 minutes for each Algebra problem. Which system of
inequalities can be used to determine the amount of a, Algebra problems, and g,
Geometry problems you can complete.
Answer: 15g+10a(less than or equal to <) 120
2g+3a<10
The system of inequalities that can be used to determine the amount of geometry problems (g) and algebra problems (a) is:
[tex]a + g \geq 10[/tex]
[tex]10a + 15g \leq 120[/tex]
We can translate the given situation into inequalities to get the system of inequalities that we can use to find the amount of algebra and geometry problems that can be completed.
Thus:a = amount of algebra problems
g = amount of geometry problems
Therefore, the inequality that at least 10 geometry and algebra problems will be:[tex]a + g \geq 10[/tex]
Thus:
15 minutes for each geometric problem = 15g
10 minutes for each algebra problem = 10a
If all is intended to be taken within 120 minutes, therefore, the inequality that represents this will be:[tex]10a + 15g \leq 120[/tex]
Therefore, the system of inequalities that can be used to determine the amount of geometry problems (g) and algebra problems (a) is:
[tex]a + g \geq 10[/tex]
[tex]10a + 15g \leq 120[/tex]

80 is the number in the square root
Step-by-step explanation:
[tex]d = \sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2} } \\d = \sqrt{(4-(-4) )^{2} +(5- 1 )^{2} }\\d = \sqrt{(4+4 )^{2} +4^{2}\\d = \sqrt{8^{2} +4^{2} }\\d=\sqrt{64 +16}\\d=\sqrt{80}[/tex]
Jonathan deposits $6,000 in a savings account that pays 2.1% interest compounded
quarterly. What is his balance after one year?
Given:
Principal= $6000
Rate of interest = 2.1% compounded quarterly.
To find:
The balance after one year.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.
We have, P=6000, r=0.021, n=4 and t=1.
Putting these values in the above formula, we get
[tex]A=6000\left(1+\dfrac{0.021}{4}\right)^{4(1)}[/tex]
[tex]A=6000\left(1+0.00525\right)^{4}[/tex]
[tex]A=6000\left(1.00525\right)^{4}[/tex]
[tex]A=6126.9957[/tex]
[tex]A\approx 6126.996[/tex]
Therefore, the balance after one year is $6126.996.

help please, solve for x
Answer:
x=18
Step-by-step explanation:
The angles here are alternate interior angles, this means that they are congruent. Congruent means that they are equal to each other, so to solve just set them equal! (Your variable is x so you're solving for that)
[tex]4x=72[/tex]
Divide both sides by 4:

Answer:
The given equation is of the form
p( x+ q)² + r = [tex]3((x+(-\frac{7}{6})^{2} +(-\frac{61}{12})[/tex]
Step-by-step explanation:
Step(i):-
Given equation 3 x² - 7 x -1
= [tex]3(x^{2} -\frac{7}{3} x )-1[/tex]
= [tex]3(x^{2} -2 X \frac{7}{3X2} +(\frac{7}{6} )^{2}-(\frac{7}{6} ^{2} )-1[/tex]
= [tex]3(x^{2} -2 X \frac{7}{6} +(\frac{7}{6} )^{2}-(\frac{49}{36} )) -1[/tex]
Step(ii):-
We know that formula
(a-b)² = a² - 2ab + b²
[tex]3x^{2} -7x-1 = 3((x-\frac{7}{6})^{2} -( 3X\frac{49}{36} )) -1[/tex]
[tex]3x^{2} -7x-1 = 3((x-\frac{7}{6})^{2} -\frac{61}{12}[/tex]
Final answer:-
The given equation is of the form
p( x+ q)² + r = [tex]3((x+(-\frac{7}{6})^{2} +(-\frac{61}{12})[/tex]
