Answer:
[tex]x < 7[/tex]
Step-by-step explanation:
1) Subtract 40 from both sides.
[tex] - 8x > - 16 - 40[/tex]
2) Simplify -16 - 40 to -56.
[tex] - 8x > - 56[/tex]
3) Divide both sides by -8.
[tex]x > \frac{ - 56}{ - 8} [/tex]
4) Two negative numbers makes a positive.
[tex]x > \frac{56}{8} [/tex]
5) Simplify 56/8 to to 7.
[tex]x < 7[/tex]
Therefor the answer is option B. x < 7.
Answer:
[tex]x<7[/tex]
Step-by-step explanation:
[tex]-8x+40>-16[/tex]
Move the constant to the right-hand side and change its sign
[tex]-8x>-16-40[/tex]
Calculate the difference
[tex]-8x>-56[/tex]
Divide both sides of the inequality by -8 and flip the inequality sign
[tex]x < 7[/tex]
Therefore the Correct Answer B. x < 7

An architect is making a plan for a new circular playground. If 64 feet is the playground's radius, how much fencing needs to go up to keep the kids in the circle?
100.48 feet
200.96 feet
401.92 feet
Answers
Answer:
209.96
Step-by-step explanation:
we know that the circumference of the circle is equal to
C = [tex]\pi D[/tex]
we have
[tex]D = 64 ft[/tex]
substitute would be
[tex]C = \pi (64) = 64\pi ft[/tex]
assume that [tex]\pi = 3.14[/tex]
64[tex]64\pi = 64 * 3.14 = 200.96 ft[/tex]

A 90% confidence interval for u using the sample results X = 131.2, s=55 , and n= 50 Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. Margin of error:? 90 Confidence Interval?
Answers
Answer:
131.2 ;
12.8 ;
(118.4, 144)
Step-by-step explanation:
Given :
X = 131.2, s=55 , and n= 50
Point estimate of the mean :
Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :
Margin of Error = Zcritical * s / sqrt(n)
Zcritical at 90% = 1.645
Margin of Error : 1.645 * (55 / sqrt(50))
Margin of Error : 1.645 * 7.7781745
Margin of Error = 12.795097
Margin of Error = 12.8
The confidence interval (C.I) :
C.I = x ± margin of error
C. I = 131.2 ± 12.8
(131.2 - 12.8) ; (131.2 + 12.8)

Suppose that the area of a square lawn is 4x^2 + 16x + 16. What is the length of one side of the lawn?
Answers
Answer:
2x+4
Step-by-step explanation:
remember the formula (a+b)^2=a^2+b^2+2ab
in this case, 4x^2 would be a^2, 16 would be b^2, and 16x would be 2ab
so, the variable a would be 2x and the variable b would be 4
so, you can turn 4x^2+16x+16 into (2x+4)^2
and since the area of a square is (one of its sides)^2, or in this case (2x+4)^2, the length of one side of the lawn will be 2x+4
problems where you have to use the (a+b)^2=a^2+b^2+2ab formula to turn trinomials into binomials squared are very common, so make sure to look out for questions like these and be ready to use this formula

Mr. Mann asked his class to form a number pattern using the rules:
Use the number 6 as the first term.
To find the other term, subtract 2 from the previous term, then multiply by 2.
The first two numbers in the pattern are 6 and 8.
What is the fourth number in the pattern?
Answers
Answer:
20
Step-by-step explanation:
when you subtract 2 from 6 you get 4. so you multiply 4 into 2 which give the answer 8. when you subtract 2 from 8 you get 6 and then you multiply 6 to 2 which gives the answer 12... next you subtract 2 from 12 which gives the answer 10. so you multiply 10 to 2 Which gives the final answer for you which is 20.
