Help please! Solve the inequality.
Answer:
x≤-3 1/2 or x>1
Step-by-step explanation:
The way we solve this is we simply rearrange the equation using algebra.
Step 1) For the first inequality, subtract 1/2 from both sides. This gets x by itself and turns the RHS into -3 1/2.
Step 2) For the second, add 3 to both sides. Once again, x is by itself, and the RHS is equal to 1.

Before it started to rain, Bobby cut 1 8 of the grass in his yard and Danny cut 1 5 of the grass in the yard. Both boys were disappointed because they were not able to cut the entire yard. Which statement is TRUE?
A) Together the boys didn't even cut half the yard.
B) The boys were able to cut more than half the yard.
C) The boys cut almost three-fourths of the yard.
D) Together the boys cut almost the entire yard.
Answer:
Option A is correct
Step-by-step explanation:
Bobby = 1/8
Danny = 1/5
Let's add up both fractions:
1/8 + 1/5 =
1*5/8*5 + 1*8/5*8 = (multiplying both the numerator and
5/40 + 8/40 = 13/40 denominator by the opposite denominator)
Together, they both cut 13/40 of the entire lawn.
Let's check each option:
A) Together the boys didn't even cut half the yard.
True, half of the yard is 20/40, and 13/40 < 20/40
B) The boys were able to cut more than half the yard.
False, half of the yard is 20/40, and 13/40 is not greater than 20/40
C) The boys cut almost three-fourths of the yard.
False, three-fourths of the yard is 30/40, and 13/40 is not close.
D) Together the boys cut almost the entire yard.
False, the entire yard is 40/40 and 13/40 is not close.

Big Pig Game Company makes checker sets and chess sets. Each day the company has available 1900 boards, which can be used for both games. They have 80,000 units of wood for making pieces. Each checker set uses 20 units of wood and each chess set uses 60 units of wood. The company that Big Pig Game Company sells to can take up to 1250 checker sets per day and up to 750 chess sets per day. The company makes a profit of $1.00 on each checker set and $2.00 on each chess set.
Requried:
a. How many checker sets and how many chess sets should the company make each day in order to maximize its profits?
b. What is the profit per day using this strategy?
Answer:
1900 divided by 20 is 95
1900 - 95 is 1805
1805 divided by 60 is 31

calculate the shaded area
Answer:
640[tex]cm^{2}[/tex]
(I hope that I am right)
Step-by-step explanation:
The bigger shape :1. First, look at the triangle as a whole -Area of a triange : [tex]\frac{Base x Height}{2}[/tex]
30 x 48 = 1440[tex]cm^{2}[/tex]
1440 ÷ 2 = 720[tex]cm^{2}[/tex]
2. Now let's look at the small triangle -20 x 16 = 320[tex]cm^{2}[/tex]
320 ÷ 2 = 160[tex]cm^{2}[/tex]
The area of the bigger shape -720 - 160 = 560[tex]cm^{2}[/tex]The smaller shape :1. Let's look at the shape as a rectangle first -Area of a rectangle = Base x Height
20 x 16 = 320[tex]cm^{2}[/tex]
2. Now let's do the little triangle -20 - 30 = 10
10 x 16 = 160[tex]cm^{2}[/tex]
160 ÷ 2 = 80[tex]cm^{2}[/tex]
The area of the smaller shape -80[tex]cm^{2}[/tex]The Area Of The Shaded Area :560 + 80 = 640[tex]cm^{2}[/tex]Find the measure of each marked angle.
Answer:
x=64
Step-by-step explanation:
180=x+2+4x-142
180=5x-140
320=5x
64=x

Answer: Refer to Below
Step-by-step explanation:
PART 1: Write an expression to model the total costGiven information
Php 2,000 activation fee
Php 1,500 monthly fee
Analysis of given information
Activation fee: the amount of money to start a charge (i.e. Let's say if there is a membership, then this fee would be the same as having a card of membership)
Monthly fee: the amount of money that would be charged monthly (i.e. Let's say if there is a membership, then this fee would be the amount of money that you would need to pay for maintenance every month)
Set variable according to the given information
Let x be the number of months for the membership
Write expression with the given information and the variable
Cost = Monthly fee × Number of months + Activation fee
[tex]\boxed{C = 1500x + 2000}[/tex]
PART 2: Evaluate the expression for 1 to 6 months of membership**Information** Since we have already written the expression in [PART 1] and defined the number of months as [x], we are going to substitute the given number of months into the expression.
Given information
Number of months = 1, 2, 3, 4, 5, 6
Written expression from [PART 1]
C = 1500x + 2000
Substitute values into the expression
1 month = 1500 (1) + 2000 = [tex]\boxed{Php 3500}[/tex]
2 months = 1500 (2) + 2000 = [tex]\boxed{Php 5000}[/tex]
3 months = 1500 (3) + 2000 = [tex]\boxed{Php 6500}[/tex]
4 months = 1500 (4) + 2000 = [tex]\boxed{Php 8000}[/tex]
5 months = 1500 (5) + 2000 = [tex]\boxed{Php 9500}[/tex]
6 months = 1500 (6) + 2000 = [tex]\boxed{Php 11000}[/tex]

Answer:
x = 11/3
Step-by-step explanation:
This is because that if you plug it in,
√x+3 = 2√x-2
√11/3 + 3 = 2√11/3 - 2
√20/3 = 2√5/3
Statement is true, therefore x = 11/3.

how many distinct 9-digit numbers can you make from four "1", three "2", and two "3"?
Answer:
2520
Step-by-step explanation:
If a nine digit number contains exactly 4 one's, 3 two's and 2 three's
We can choose the positions of the 1's in P(9/4) ways.
We can choose the positions of the 2's from the five remaining positions in P(5/3) ways
We can choose the positions of the 3's from the two remaining positions in P(2/2) ways
In this problem order doesnt matter..
= (9!/5!×4!) × (5!/3!×2!) × (2!/2!×0!)
= 2520

A cell phone company has noticed that the probability of a customer experiencing a dropped call decreases as the
customer approaches a cell site base station. A company representative approached a cell site at a constant speed and
calculated the probability of a dropped call at regular intervals, and the probabilities formed the geometric sequence
08, 04.02,01,005. If the company representative continues calculating the probability of a dropped call, what will
be the next term in the sequence?
A
0.025
B)
000S
0.010
D)
0.0005
Answer:
The next term in the sequence is:
0.00221184
Step-by-step explanation:
We are given that:
A cell-phone company has noticed that the probability of a customer experiencing a dropped call decreases as the customer approaches a cell-site base station.
A company representative approached a cell site at a constant speed and calculated the probability of a dropped call at regular intervals, and the probabilities formed the recursive sequence:
0.6, 0.4, 0.24, 0.096, 0.02304.
as we can see third term is product of first two terms
fourth term is product of third and second term
fifth term is the product of fourth and third term
so, the next term in the sequence which is the sixth term will be the product of fifth and fourth term= 0.02304×0.096
= 0.00221184

What are the vertex and x intercepts of the graph of the function below
y=(x-4)(x + 2)
Answer:
x - intercepts: (4,0) and (-2,0)
vertex: (1/2 , - 17/2)
Step-by-step explanation:
Part A
To find the x-intercepts you have to set y=0
(x-4) (x+2) = 0
Separate the parenthesis. Solve for x
x-4 = 0
x= 4
x+2 = 0
x= -2
x - intercepts: (4,0) and (-2,0)
-------------------------------------------------
Part B
vertex formula for the x: coordinate : -b/2a
Expand the function.
y = 2x^2-2x-8
a = 2
b = -2
c= -8
-b/2a = -(-2)/2(2) = 1/2
vertex x- coordinate: 1/2
Substitute 1/2 back into every "x" in the function to find the "Y" for the vertex.
y = 2(1/2)^2 -2(1/2) -8
y = -17/2
vertex: (1/2 , - 17/2)

What system of linear equations is shown in the graph? Enter your answers in the box.
Answer:
The equation of the line with a bold line:
slope = ( 0 - ( -1 ) ) / ( ( 2 - 0 ) )= 1/2
c = -1
Therefore, y <= ( 1 / 2 ) x - 1
The equation of the line with the dotted line:
slope = ( 1 - ( - 2 ) ) / ( 0 - 1) = - 3
c = 1
Therefore, y < - 3x + 1

Evaluate the function
f(x) = - 2x^2 + 2x + 4
Find f(1)
Answer:
f(1) = 4
Step-by-step explanation:
f(x) = - 2x^2 + 2x + 4
f(1) = - 2(1)^2 + 2(1) + 4
f(1) = -2 + 2 + 4
f(1) = 4
