Does anyone know the answer to this , its math inequalities
48 > -6x
Answer:
[tex]x > - 8[/tex]
Step-by-step explanation:
Swap the sides of the inequality and flip the inequality sign:
[tex] - 6x < 48[/tex]
Divide both side of the inequality by -6 and flip the inequality sign:
[tex]x > - 8[/tex]
[tex]48 > - 6x \\ \\ \\ Change \: The \: Sides \\ Of \: Value \: With \: Signs \\ \\ \implies - 6x < 48 \\ \\ \implies \: x > - 8[/tex]

Please help, it’s due in 10 minutes
Answer:
The answer:
n= 1/6
n=0.16
Answer:
log64/ log 16 -2 / -3
Step-by-step explanation:
(-3n +2) = log64/log16
-3n = log64/log16 - 2
n = log64/log16 -2 /-3
I divide both sides by log theres another way to do it but I forget. it etheir becomes 64^16 -2/3 or 16^6= -2 /3

One plumber charges a flat fee of $50 to come to the house and then
$20 per hour. If h represents the number of hours that the plumber spent
fixing the problem and C represents the total charge, which of the following
equations shows how to determine the total fee charged?
C=50+20h
C=(50+20)h
C=h+50+20
C=20+50h
Answer:
C=50+20h
Step-by-step explanation:
The $50 dollars in this equation is a flat fee, no variable to it. It doesn't increase or decrease depending on the number of hours. The $20 dollars is dependent on the number of hours the plumber works. If the plumber works 2 hours they get $40 dollars, the amount the plumber receives depends on the hours worked. The h in the equation is a placeholder for hours worked. To solve the equation just replace h with the hours worked and solve to get the answer.
A ski resort claims that there is a 75% chance of snow on any given day in January and that snowfall happens independently from one day to the next. A family plans a four-day trip to this ski resort in January. Let X represent the number of days it snows while the family is there. What are the mean and standard deviation of X?
Option Choices:
Answer:
Its D
Step-by-step explanation:
Using the binomial distribution, it is found that the mean and the standard deviation of X are given as follows:
[tex]\mu_X = 3, \sigma_X = 0.87[/tex]
What is the binomial probability distribution?The expected value of the binomial distribution is:
[tex]\mu_X = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sigma_X = \sqrt{np(1-p)}[/tex]
In this problem, the proportion and the sample size are given as follows:
p = 0.75.n = 4.Hence, the mean and the standard deviation are given by:
[tex]\mu_X = np = 4(0.75) = 3[/tex]
[tex]\sigma_X = \sqrt{np(1-p)} = \sqrt{4(0.75)(0.25)} = 0.87[/tex]

A freshly isolatedsample of 90Y was found to have an activity of 8.9 x 105 disintegrations per minute at 1:00pm on December 3, 2003. At 2:15pm on Dec, 17, 2003, its activity was redetermined and found to be 2.6 x 104 disintegrations per minute. Calculate the half-life of 90Y.
Answer:
3960 minutes
Step-by-step explanation:
From;
0.693/t1/2 = 2.303/t log No/N
t1/2 = half life of 90Y
No = initial activity of 90Y = 8.9 x 10^5 disintegrations per minute
N= activity of 90Y after time t = 2.6 x 10^4 disintegrations per minute
t = time taken
Since the time elapsed is 20,235 minutes, we substitute into the formula above.
0.693/t1/2 = 2.303/20235 log 8.9 x 10^5/2.6 x 10^4
0.693/t1/2 = 1.75 * 10^-4
t1/2 = 0.693/ 1.75 * 10^-4
t1/2 = 3960 minutes
Erin records the following temperatures (in degrees
Fahrenheit) at noon during one week:
91, 95, 95, 95, 92, 95, 93
These temperatures do not contain an extreme value.
Which measure of center should Erin use to describe the temperatures?
O A. Mean absolute deviation (MAD)
B. Either the mean or the median. The values are about the same.
C. Interquartile range (IQR)
O D. Range
Answer:
I think the correct answer should be B
Answer:
B
Step-by-step explanation:
B because there is no extreme values
A 10 foot ladder is leaning against a building. It forms a 30 degree angle with the ground. How far away from the building is the foot of the ladder? Round your answer to the nearest hundredth. 5 feet, 5.77 feet, 8.66 feet, or 20 feet
x = 8.66 ft
Step-by-step explanation:
cos 30 = adj/hyp = x/10
---> x = (10 ft)cos30
= 8.66 ft

what is the 5th term of the expansion of (3x+y^4)^7
9514 1404 393
Answer:
945x^3·y^16
Step-by-step explanation:
The 5th term will be ...
C(7,4)(3x)^3(y^4)^4 = 35·27·x^3·y^(4·4)
= 945x^3·y^16
_____
The coefficients of the expansion are C(n, k) where n is the exponent of the binomial, and k+1 is the term number. This is n!/(k!(n-k)!). The general (k-th) term of the expansion (a+b)^n is C(n, k)a^(n-k)b^(k) where k ranges from 0 to n.

if two supplementary angles is in the ratio 7:8 find the complement of the smaller angle
Answer:
6°
Step-by-step explanation:
Let
the supplementary angles be 7x and 8x so,
7x+8x=180 ,15x=180 ,x=180/15 ,x=12
smaller angle=7x=7×12=84°
complement of 84°=90°-84°=6°
the store is selling lemons at 0.53 each. each lemon yields about 2 tablespoons of juice. how much will it cost to buy enough lemons to make three 9inch lemon pies, each requiring half a cup of lemon juice?

3 pies require 3/2 cups of lemon juice
16 tablespoons = 1 cup
need 24 tablespoons of lemon juice
need 12 lemons at $0.53 each
total cost = 12 x 0.53 = $6.36

Isa is allowed to play games for 5/3 hours a day she already play 4/3 hours today
What fraction of an hour does Isa have left to play video games today?
Answer:
1/3 of an hour
Step-by-step explanation:
Because we already have the same common denominator, subtract the numerators to solve:
[tex]\frac{5}{3} -\frac{4}{3} = \frac{1}{3}[/tex]
Isa has 1/3 of an hour left to play video games (20 minutes).
