Answer:
x>20
Step-by-step explanation:
Hi there!
[tex]120-5x < 20[/tex]
Subtract 120 from both sides
[tex]120-5x -120< 20-120\\-5x<-100[/tex]
Divide both sides by -5 and switch around the inequality symbol (because we're dividing by a negative number)
[tex]\frac{-5x}{-5} >\frac{-100}{-5} \\x>20[/tex]

Can y’all help me on question 11?!
Answer:
The correct answer is choice C.
Step-by-step explanation:
To find the area of the arrow, we must add together the areas of the rectangle and the triangle that make up the arrow. The rectangle has a length of 10 inches and a width of 4 inches, and the triangle has a base of 8 inches and a height of 2 inches. Using this information, we can plug numbers into the following formula:
Area of arrow = area of rectangle + area of triangle
Area of arrow = (10*4)+(1/2*8*2)
Area of arrow = 40 inches squared + 8 inches squared
Area of arrow = 48 inches squared
Therefore, the correct answer is option C, 48 square units (in this case, inches).
Hope this helps!

Select the best answer for the question.
5. Determine the diameter of a circle with circumference units.
O A. Tt2 units
O B. 1 unit
O C. T units
O D. 2 units
Mark for review (Will be highlighted the review page)
<< Previous Question
Next Question >>
Answer:
B. 1 unit
Step-by-step explanation:
the circumference of a circle is
Cc = 2×pi×r
r = radius = diameter / 2
now we need to find the diameter (= 2×r) of a circle with the circumference of pi.
=>
pi = 2×pi×r
1 = 2×r = diameter
so, the diameter is 1 unit.
Given: g(x) = x - 4 and h(x) = 2x - 8. What is g(h(1011?
Answer:
[tex]g(h(1011)) = 2010[/tex]
Step-by-step explanation:
Given
[tex]g(x) = x - 4[/tex]
[tex]h(x) =2x - 8[/tex]
Required
[tex]g(h(1011)[/tex]
First, we calculate [tex]g(h(x))[/tex]
[tex]g(x) = x - 4[/tex]
Substitute h(x) for x
[tex]g(h(x)) = h(x) -4[/tex]
Substitute [tex]h(x) =2x - 8[/tex]
[tex]g(h(x)) = 2x - 8 -4[/tex]
[tex]g(h(x)) = 2x -12[/tex]
Substitute 1011 for x
[tex]g(h(1011)) = 2*1011 -12[/tex]
[tex]g(h(1011)) = 2022 -12[/tex]
[tex]g(h(1011)) = 2010[/tex]

y=-16x^2+239x+127
Answer:
7.47 seconds
Step-by-step explanation:
From the quadratic equation the x coordinate of the vertex is
x = -b/(2a)
---------------------------
y = -16x² + 239x + 127
x = -239/ ( 2 * (-16) )
x = -239 / (-32)
x = 7.46875
Rounded
x = 7.47
6.) Ms. Speer is scuba diving. She descends 5 feet below sea level. She descends the same distance 4 more times. What is Ms. Speer's final elevation? *
Answer:
-25 feet
Step-by-step explanation:
First she descends 5 feet below sea level
She then descends the SAME DISTANCE ( so 5 feet ) 4 MORE TIMES
So feet descended = 4 * 5 + 5
4 * 5 = 20
20 + 5 = 25
Her final elevation will be -25 feet
( it's important that we add a negative sign because she is descending meaning going down )
Select the correct answer.
Which point is a reflection of 01-4, -6) across the x-axis and the -axis?
a) point a
b) point b
c)point c
d)point d
Answer:
If we have a point (x, y), a reflection across the x-axis converts the point to (x, -y)
While a reflection across the y-axis converts the point to (-x, y)
Then if we apply both of these transformations to our point, the reflection of (x, y) across the x-axis and then across the y-axis is (-x, -y)
Then the reflection of (-4, -6) across these two axes, is:
(- (-4), - (-6)) = (4, 6)

In 2006 the number of tickets sold was 210.
The ratio Number of adult tickets: Number of student tickets was 23:19.
How
many
adult tickets were sold?
Answer:
115
Step-by-step explanation:
There were 115 adult tickets were sold.
What is ratio?A ratio shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six.
Given that, the number of tickets sold was 210. The ratio Number of adult tickets: Number of student tickets was 23:19.
Let the number of tickets sold for adults be 23x and for students be 19x
Therefore, 23x+19x = 210
42x = 210
x = 210/42
x = 5
So, Number of adult tickets = 5x23 = 115
Hence, There were 115 adult tickets were sold.

In the Minnesota Northstar Cash Drawing, you pick five different numbers between 1 and 35. What is the probability of picking the winning combination (order does not matter)
Answer:
[tex]\frac{1}{324632}[/tex] probability of picking the winning combination
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Since the order is not important, the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
The correct five numbers from a set of 5. So
[tex]D = C_{5,5} = \frac{5!}{5!0!} = 1[/tex]
Total outcomes:
Five numbers from a set of 35. So
[tex]T = C_{35,5} = \frac{35!}{5!30!} = 324632[/tex]
Probability:

Raw scores on behavioral tests are often transformed for easier comparison. A test of reading ability has mean 67 and standard deviation 10 when given to third graders. Sixth graders have mean score 86 and standard deviation 9 on the same test. To provide separate "norms" for each grade, we want scores in each grade to have mean 100 and standard deviation 20. (Round your answers to two decimal places.)
(a) What linear transformation will change third-grade scores x into new scores xnew = a + bx that have the desired mean and standard deviation? (Use b > 0 to preserve the order of the scores.) a = b = (b)

Answer:
a.) a = -34 and b = 2
b.) a = -91.11 b = 2.22
c.) David scored 124, nancy scored 84.27
David scored higher
Step-by-step explanation:
for those in the 3rd grade
mean u = 67
s = 10
we used the z formula
[tex]z=\frac{x-u}{s}[/tex]
[tex]z=\frac{x-67}{10}[/tex]
we have the new score
u = 100
s = 20
we use this formula [tex]z*s+u[/tex]
[tex][\frac{x-67}{10} ]20\\[/tex] + 100
multiply through by 20
[tex][\frac{20x-1340}{10} ] +100[/tex]
dividing the bracket by 10
= [tex]2x-134+100[/tex]
= [tex]2x-34[/tex]
from this solution above,
a = -34 and b = 2
b.)
we solve for those in the 6th grade
u = 86
s = 9
[tex]\frac{x-86}{9}[/tex]
for new score,
y = 100
s = 20
[tex][\frac{x-86}{9} ]20+100[/tex]
[tex]2.22x-191.11+100\\= 2.22x - 91.11[/tex]
from this solution
a = -91.11
b = 2.22
c.) if David scored 79
[tex]= 2(x)-34[/tex]
= 2(79) - 34
= 158 - 34
= 124
if nancy scored 79
= 2.22(79) - 91.11
= 175.38 - 91.11
= 84.27
from these scores we can see that David scored higher in his grade

What is the domain of the function graphed below?
Answer:
x < 7
Step-by-step explanation:
the domain of a function defines the valid x values for the function.
as we go from left to right through all possible values of x, we see all values incl. x=-1 are creating a valid function result (y) for this function. until we reach x=7.
the empty ball indicates that there is no y value defined here. and for any value x>7 there is no y value defined.
so, x < 7 is the right one.
