A.

-4n+11>-9 Subtract 11 from both sides
-4n>-20 then, divide both sides by -4
In these greather than less than equations, when you divide a negative by another negative, you must flip the sign
so that would be, n<5

10) Go through each answer choice & check.
a) 4n + 11 > -9
Subtract 11 from both sides.
4n > -9 - 11
Simplify.
4n > -20
Divide both sides by 4.
n > -5
(a) is incorrect.
b) 4n + 11 < -9
Subtract 11 from both sides.
4n < -9 - 11
Simplify.

rosa, roberto, andrea, and inno find an estamate for the square root of ten who has proposed the best solution
Rosa, use the square root of 9 and the square root of 25
Roberto, use the square root of 4 and the square root of 90
Andrea, use the square root of 11 and the square root of 12
Inno, use the square root of 9 and the square root of 16
Answers
Final answer:
Inno's solution of using the square root of 9 and 16 is the best estimate for the square root of ten, as it provides a narrower and more accurate range for the estimate.
Explanation:
To estimate a square root that is not a perfect square, one strategy is to find integers that the number falls between, and then those integers' respective square roots give us a range within which the square root of the number will fall.
Rosa and Inno's approaches are similar and most appropriate because they both use 9 and another square number that is close to 10.
Rosa uses the square roots of 9 and 25. Since the square root of 9 is 3, and the square root of 25 is 5, we know that √10 is a little more than 3, because 10 is closer to 9 than it is to 25. Inno uses the square roots of 9 and 16. Since the square root of 16 is 4, √10 is closer to 3 than 4 because 10 is closer to 9.
Therefore, Inno's solution gives a closer estimate of the square root of 10, as it falls between 3 and 4 (and closer to 3), and this is the best solution among those proposed.

Martin had 7 pounds of grapes left, and he gave away 2/5 of them. Explain how to use compatible numbers to estimate the amount of grapes he gave away.
Answers
Answer:
Step-by-step explanation:
The amount of grapes that he gave away is 3.5 pounds.
Number of grapes with Martin = 7 pounds
Fraction given away = 2/5
In this case, to use compatible numbers, we have to find a fraction that's close to 2/5 which will be 1/2.
Then, we have to multiply 1/2 by 7 and this will be:
= 1/2 × 7
= 3.5
In conclusion, the amount of grapes that he gave away is 3.5 pounds.

Answers
9 is less than x is -1
I will take the liberty of deleting the first "is" and then write out the expression:
9 less than x is -1, or x-9 = -1
Add 9 to both sides to determine the value of x: x = 8 (answer)
The sentence "9 is less than x is -1" written as an equation is A. 9 - x = -1
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given sentence is,
9 is less than x is -1
So, since less than means subtraction
Therefore 9 is less than x is written as,
9 - x
And this equal to -1
So we can write,
9 - x = -1
which the required equation of the given sentence.
The sentence "9 is less than x is -1" written as an equation is 9 - x = -1
Thus the correct answer is A. 9 - x = -1.

Calculate the z-score for 95 wpm: z = --------------- = --------

This fraction is approx. equal to 0.583.
Look in the body of a table of positive z scores for this 0.583. The table will give you a decimal fraction that represents the area to the LEFT of z=0.583.
Subtract that result from 1.000 to obtain the probability that a student's typing skills will be greater than 95 wpm. If you have a calculator with the normal cumulative density function (normalcdf) built in, find the area under the normal curve to the left of 0.583 and then subtract this result from 1.000.
My calculator result was 1.000-0.720 = 0.280.

Factor 3/4 out of 3/4z + 6
Answers
[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 8 )[/tex]
EXPLANATION
We want to factor
[tex] \frac{3}{4} [/tex]
out of
[tex] \frac{3}{4} z + 6[/tex]
The first term is already having a factor of
[tex] \frac{3}{4} [/tex]
The constant term which is the second term is not having a factor of
[tex] \frac{3}{4} [/tex]
so we need to use a trick of multiplying and dividing by the same factor to obtain,
[tex] \frac{3}{4} z + 6 = \frac{3}{4} z + \frac{3}{4} \times \frac{6}{ \frac{3}{4} } [/tex]
We can now factor
[tex] \frac{3}{4} [/tex]
out of the right hand side to obtain,
[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + \frac{6}{ \frac{3}{4} } )[/tex]
Let us rewrite the right most fraction using the normal division symbol.
[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 6 \div \frac{3}{4} )[/tex]
We simplify to obtain,
[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 6 \times \frac{4}{3} )[/tex]
This further gives us,
[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 2 \times 4 )[/tex]
[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 8 )[/tex]
Daniel is completing a home project. He needs 13 pieces of wood, each 1 1/2 feet long, to complete the project. How much wood does Daniel need to complete his home project?
8 2/3 ft
11 1/2 ft
14 1/2 ft
19 1/2 ft
Answers
Answer:
Daniel will need [tex]19\frac{1}{2}[/tex] feet wood to complete his home project.
Step-by-step explanation:
We are told that Daniel needs 13 pieces of wood, each [tex]1\frac{1}{2}[/tex] feet long, to complete his home project.
To find total amount of wood needed we will multiply number of wood pieces by length of each wooden piece.
First of all we will convert our mixed fraction to improper fraction as: [tex]1 \frac{1}{2} =\frac{3}{2}[/tex]
Now let us multiply our values.
[tex]13*\frac{3}{2} =\frac{39}{2}[/tex]
Now we will convert this improper fraction to mixed fraction to find our final answer.
[tex]\frac{39}{2}=19\frac{1}{2}[/tex]
Therefore, Daniel needs [tex]19\frac{1}{2}[/tex] feet wood to complete his home project.
