Factor the algebraic expression -18y - 27
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
-18y = (-1) * 3 * 3 * 2 * y
-27 = (-1) * 3 * 3 * 3
Common factors = (-1) * 3 * 3 = - 9
-18y - 27 = -9*2y - 9 * 3
=(-9) [2y + 3]

What is the value of the following expression for a = -1 and b = 4?
13a^-3 b^-1
A. -13/4
B. -52
C. -4/13
D. -156
Well, if a = -1 and b = 4 then when we plug in the values of a and b into the expression we get:
[tex]13(-1)^{-3}\cdot4^{-1}[/tex].
Then simplify it:
[tex]-13\cdot1/4=-\frac{13}{4}[/tex].
The answer is A.
Hope this helps.
Step-by-step explanation:
Step 1: Substitute -1 for a and 4 for b
[tex]13 * (-1)^-^3 * (4)^-^1[/tex]
[tex]13 * (-1) * \frac{1}{4}[/tex]
[tex]-\frac{13}{4}[/tex]
Answer: Option A, [tex]-\frac{13}{4}[/tex]

anyone help me please?
Answer:
The angle is 36.87°
Step-by-step explanation:
To find the missing angle, we will have to use inverse SOH-CAH-TOA.
Looking at the angle, as well as the two sides, we can infer that the opposite of the unknown angle is 24. Since the given side is not the hypotenuse but the adjacent, we know that we will be using inverse tangent (TOA).
[tex]tan^{1}[/tex] (x) = [tex]\frac{24}{32}[/tex]
x = [tex]tan^{-1}[/tex] ([tex]\frac{24}{32}[/tex])
x = 36.87°
Answer:
≈ 36.9
Step-by-step explanation:
You are given the opposite and adjacent side, leading you to use tan. However, since you're trying to find the angle measurement, and not the side, you use the inverse of tan: [tex]tan^-1[/tex]
Set it up like this:
[tex]tan^-1 (\frac{24}{32})=?[/tex]
When you solve, you get:
36.86
Round to the nearest tenth:

A parallelogram has a base of 8.5 cm and a height of 6 cm. What is the area of the parallelogram
Answer:
51cm^2
Step-by-step explanation:
The formula for the area of a parallelogram is : [tex]base*height[/tex]
To work out the area of a parallelogram you would simply multiply the base of 8.5 by the height of 6, this gives you 51cm^2. This is because the formula for the area of a parallelogram is base multiplied by the height.
1) Multiply 8.5 by 6.
[tex]8.5*6=51cm^2[/tex]

Solve by substitution
y=2x-3
-x-8y=7
Answer & Step-by-step explanation:
y = 2x - 3
-x - 8y = 7
Since, we have a equation for y, then we can substitute this equation for y to solve for x.
-x - 8(2x -3) = 7
-x - 16x + 24 = 7
-17x + 24 = 7
-17x = -17
x = 1
So, since we know that x is equal to 1, then we can plug in this number for the equation of y to find y.
y = 2(1) - 3
y = 2 - 3
y = -1
So, the solution is (1, -1). X equals 1 and y equals -1.

You deposit $1500 in a bank account that pays 4% annual interest. Find the balance
after 6 years if the interest is compounded monthly. Round to the nearest cent.
Growth
Answer:
To calculate the balance after 6 years with monthly compounding, we can use the formula for compound interest:
A = P * (1 + r/n)^(n*t)
Where:
A = the final amount (balance) after t years
P = the principal amount (initial deposit)
r = the annual interest rate (as a decimal)
n = the number of times interest is compounded per year
t = the number of years
In this case:
P = $1500
r = 4% = 0.04 (as a decimal)
n = 12 (compounded monthly)
t = 6 years
Plugging in the values, we get:
A = 1500 * (1 + 0.04/12)^(12*6)
Calculating the right-hand side:
A = 1500 * (1 + 0.003333)^72
A = 1500 * (1.003333)^72
A ≈ 1500 * 1.265032
A ≈ $1897.55
Therefore, the balance after 6 years with monthly compounding, rounded to the nearest cent, is approximately $1897.55.

2) The sum of two numbers is 100. Their difference is 4. What are the two numbers?
Answer: 48, 52
Step-by-step explanation:
The sum of the two numbers (x, y) is 100. This means that;
x+y=100
Their difference is 4, so;
y=x+4
Now, you can substitute that in for y;
x+(x+4)=100
Simplify;
2x+4=100
2x=96
x=48
Now, we plug in the value of x to the second equation;
y=48+4
y=52
Answer:
48 and 52
Step-by-step explanation:
We have a pair of simultaneous equations and will solve these using substitution.
x + y = 100 (1)
x - y = 4 (2)
Solve for x:
x+y=100 , x - y = 4
x=52
Substitute x with 52
(52) + y = 100 , (52) - y = 4
Simplify:
y = 48

What is a mixed number betweeen 3 3/11 and 3 2/5
Answer:
3 4/11.
Step-by-step explanation:
3/11 = 15/55

-2(3a+1) = 5(1+a)
What is a? And how do get the answer?
Just solve the equation
Given:
-2(3a+1) = 5(1+a)
-6a - 2 = 5 + 5a
11 a = -7
a = -7/11
Answer:
a = -7/11
Step-by-step explanation:
Distribute -2 and 5 through the parentheses, -6a - 2 = 5 + 5a
Move the Variable and constant to a proper side, -6a - 5a = 5 + 2
Calculate like terms, -11a = 7
Divide both sides of the equation by -11, a = -7/11
Final answer, a = -7/11

write a table to show your steps for calculating the standard deviation and then use your table to calculate the standard deviation of the values listed:
10, 11, 12, 10.5, 11.25, 12.25, 10
Answer:
The standard deviation for the given data set is 1.65.Step-by-step explanation:
The Standard Deviation is defined as
[tex]\sigma =\sqrt{\frac{\Sigma (x_{i} -\mu)^{2} }{N-1} }[/tex]
Where [tex]\sigma[/tex] is the standard deviation, [tex]\mu[/tex] is the mean and [tex]N[/tex] is the total number of data.
So, first, we need to find the mean of the data set.
[tex]\mu = \frac{10+11+12+10.5+11.25+12.25+10}{7} =11[/tex]
Now, we have to subtract each data with the mean to then elevate the differnece to the square power.
[tex]10-11 = -1 \implies (-1)^{2}=1\\ 11-11 = 0 \\12-11 = 1 \implies 1^{2}=1\\ 10.5-11 = -0.5 \implies (-0.5)^{2} =0.25\\11.25 - 11 = 0.25 \imples (1.25)^{2}=0.0625\\12.25 - 11 = 1.25 \implies (1.25)^{2}=1.5625\\10-11 = -1 \implies (-1)^{2}=1[/tex]
Then, we sum all these results.
[tex]\Sigma (x_{i}- \mu )^{2}=1+0+1+0.25+0.0625+1.5625+1=16.278[/tex]
Next, we divide the sum by [tex]N-1=7-1=6[/tex]
[tex]\frac{\Sigma (x_{i}-\mu )^{2} }{N-1}=\frac{16.278}{6} \approx 2.713[/tex]
Finally, we apply the square root.
[tex]\sigma = \sqrt{2.713} \approx 1.65[/tex]
Therefore, the standard deviation for the given data set is 1.65.
