Solve for 'p'. Show all work: 2(-4x + 8) ≤ 20
Answers
Answer: Answer: x≥ −1 /2
Step-by-step explanation:
Answer:
x ≥ -1/2 or x ∈ [-1/2, +∞)
Step-by-step explanation:
2(-4x + 8) ≤ 20
divide both sides by 2
-4x + 8 ≤ 10
move 8 to the right
-4x ≤ 10-8
-4x ≤ 2
divide both sides by -4. Flip the sign since a negative value is being divided

I have a cockroach problem in my living room. Don't ask how but I counted 64 cockroaches today. And they are
growing at a rate of 25% every day.
How many cockroaches do you think I'll have after three days?
Answers
If they are growing at a rate of 25% every day you can expect to have approximately 100 cockroaches in your living room.
What is growth rate?Growth rate refers to the rate at which something (such as a population, a quantity, or a value) increases or decreases over a certain period of time.
Assuming that the growth rate is compounded daily, we can calculate the number of cockroaches you will have after three days using the formula for exponential growth:
[tex]N = N_0(1 + r)^t[/tex]
Where:
N₀ is the initial number of cockroaches (64 in this case)
r is the growth rate (25% or 0.25 in decimal form)
t is the time in days (3 in this case)
N is the number of cockroaches after t days
Plugging in the values, we get:
[tex]N = 64(1 + 0.25)^3[/tex]
[tex]N = 64(1.25)^3[/tex]
N = 64(1.5625)
N = 100
Thus, after three days, you can expect to have approximately 100 cockroaches in your living room.

given cot A= 40/9 and that angle A is in quadrant 1 find the exact value of sec A in the simplest radical form using a rational denominator
Answers
Answer:
41/40Step-by-step explanation:
Given cotA = 40/9
1/tanA = 40/9
tanA = 9/40
According to SOH, CAH, TOA
tan A = 9/40 = opposite/adjacent
Get the hypotenuse
hyp² = opp²+adj²
hyp² = 9²+40²
hyp² = 81+1600
hyp² = 1681
hyp = √1681
hyp = 41
Het sec A
sec A = 1/cosA
Since cos A = adjacent/hypotenuse
cos A = 40/41
secA = 1/(40/41)
SecA = 41/40
Hence the exact value of secA is 41/40

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500.If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is
Answers
Answer:
20x + 45y = 9500 is the linear equation for given scenario
Step-by-step explanation:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Therefore, the linear equation for given scenario is found
Answer:
20x + 45y = 9500
yes/no: no
Solution:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
If eve raises exactly $9,500, it is NOT possible for there to be 220 participants in the 5K race.
