All angles in a triangle add up to 180°.Step-by-step explanation:
Step 1: Set up equation
x + 100 + 50 = 180
Step 2: Solve for x
Combine like terms: x + 150 = 180Subtract 150 on both sides: x = 30°What is the value of x in the equation −6 + x = −3?
Answer:
x = 3
Step-by-step explanation:
Simply solve for x.
In this equation all we have to do is add 6 to both sides of the equation to solve for x.

Step-by-step explanation:
You agree to purchase a home for $200,000 and decide to make a 20% down payment on the home. You finance the rest of the home payment with a 15 year fixed rate mortgage with an annual interest rate of 5.25%. Assuming that you make regular monthly payments, determine your regular monthly payment amount. Provide just a numerical answer rounded to the nearest cent.
Answer:
a or 1. $40,000 is the down payment
b or 2. 180 months = 15 years
c or 3. $168,400 is the left over payment (including mortgage)
d or 4. $935.56 (the monthly payment)
Step-by-step explanation:
1. To calculate the down payment, we need to calculate 20% of $200,000.
200,000 x 0.20 = $40,000
Therefore, the down payment on the home costs $40,000.
2. Now, let's figure out how many months are in 15 years.
15 x 12 = 180
So, the mortgage will be paid in 180 months.
3. Next, we need to find out how much money needs to be paid in the 15 years.
200,000 - 40,000 = $160,000
This price will also include an annual interest rate of 5.25%. So, we need to find 5.25% of $160,000.
160,000 x 0.0525 = $8,400 <--- interest rate when rounded to the nearest cent.
160,000 + 8,400 = $168,400 <--- total amount over 15 years
4. To find the monthly payment, we must divide the total amount of money ( or $168,400), by the number of months, (or 180.)
$168,400 ÷ 180 = $935.56 when rounded to the nearest cent.

Write the slope-intercept form of the equation of the line that passes through the given points.
(1, 1) and (-3, -3)
Answer:
Slope=1
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where x1,y1= (1, 1) and X2,y2=(-3, -3)
Slop=1+3/1+4
=4/4
=1
So the slope is 1.
Answer:
1
Step-by-step explanation:
Here,
x₁ = 1 and x₂ = (-3)
y₁ = 1 and y₂ = (-3)
Now,
Slope
= y₁ - y₂ ÷ x₁ - x₂
= ( 1 ) - (- 3) ÷ ( 1 ) - (- 3)
= 1 + 3 ÷ 1 + 3
= 4 ÷ 4 = 1
Thus, Slope is 1

Step-by-step explanation:
Answer:
A.$3.90
Step-by-step explanation:
So we have $26 and the tip is 15%, so we just find 15% of $26A percentage is a number divided by 100, so 15% is the fraction [tex]\frac{15}{100}[/tex] Now what fraction of 26 is [tex]\frac{15}{100}[/tex] ? We multiply and seeSo [tex]\frac{15}{100}*26=\frac{15*26}{100}=\frac{390}{100}=3.90[/tex] so $3.90 is 15% 0f $26 Then $3.90 is the amount of the tipWhich inequality is shown in the graph below?

what positive whole number can you multiply by 3 and add1,or multiply by 2 and add 8?
Answer:
7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
Step-by-step explanation:
Multiplying the positive whole number 7 by 3 and adding 1 will get:
(7 × 3) + 1 = 21 + 1 = 22
Multiplying the positive whole number 7 by 2 and adding 8 will get:
(7 × 2) + 8 = 14 + 8 = 22
Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Errol bought a skateboard helmet on sale at 40% off. The original price was $49.95. What is the amount of discount?
Answer:
[tex]Discount = \$19.98[/tex]
Step-by-step explanation:
Given
[tex]Amount = \$49.95[/tex]
[tex]Price\ Off = 40\%[/tex]
Required
Determine the discount
The discount is calculated by multiplying the price off by the original price:
[tex]Discount = Amount * Price\ Off[/tex]
[tex]Discount = \$49.95 * 40\%[/tex]
Convert % to decimal
[tex]Discount = \$49.95 * 0.40[/tex]
[tex]Discount = \$19.98[/tex]
Hence, the amount of discount is $19.98

A population of geese doubles every 18 months. If there are 5 geese initially, how many years will it take for there to be 111 geese?
Answer: 7 years
Step-by-step explanation:
Let t be the number of periods in which geese doubles .
The exponential growth function:[tex]y=Ab^t[/tex] , where A = initial value , b= growth factor.
As per given , A = 5 , b=2
i.e. Number of geese after t periods = [tex]y=5(2)^t[/tex]
Put y=111, we get
[tex]111=5(2)^t\\\\\Rightarrow\ \dfrac{111}{5}=2^t\\\\\Rightarrow\ 22.2=2^t[/tex]
Taking log on both sides , we get
[tex]\log 22.2 = t\log 2\\\\\Rightarrow\ 1.346353=t(0.30103)\\\\\Rightarrow\ t=\dfrac{1.346353}{0.30102}\\\\\Rightarrow\ t=4.47263636\approx4.47[/tex]
Now , total months = 4.47 x 18 =80.46≈ 80 months
since 1 year =12 months
Number of years it will take [tex]=\dfrac{80}{12}=\dfrac{20}{3}=6.66666666667\approx7[/tex]
Hence, it will take 7 years (approx.)
The graph of g is a vertical shrink by a factor of 1/3 and a reflection in the y-axis, followed by a translation 3 units right of the graph of f(x)=x2. Write a rule for g.
Answer: g(x) = (1/3)*(-x)^2 + 3.
Step-by-step explanation:
Let's define all the transformations in a general way,
A vertical contraction/dilation of a scale factor a is written as:
g(x) = a*f(x)
where if a > 1, it is a dilation.
if 0 < a < 1, it is a contraction.
A reflection in the y-axis changes the value of the x-component and leaves the y-component invariable, then this transformation is written as:
g(x) = f(-x).
A translation of A units up (A positive) is written as:
g(x) = f(x) + A.
Then for this case we have:
A dilation with scale factor 1/3.
g(x) = (1/3)*f(x)
A reflection over the y-axis.
g(x) = (1/3)*f(-x)
A translation of 3 units up.
g(x) = (1/3)*f(-x) + 3
(in that order, remember that the order in which you applly the transformations matters)
Then g(x) = (1/3)*f(-x) + 3
and f(x) = x^2, so we can replace that in the equation for g(x)
g(x) = (1/3)*(-x)^2 + 3.
Transformation involves changing the position of a function.
The rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]
The parent function is given as:
[tex]\mathbf{f(x) = x^2}[/tex]
The rule of vertical shrink by a factor of 1/3 is:
[tex]\mathbf{(x,y) \to (x,\frac 13y)}[/tex]
So, we have:
[tex]\mathbf{f'(x) = \frac 13x^2}[/tex]
The rule of reflection across the y-axis is:
[tex]\mathbf{(x,y) \to (-x,y)}[/tex]
So, we have:
[tex]\mathbf{f''(x) = \frac 13(-x)^2}[/tex]
[tex]\mathbf{f''(x) = \frac 13x^2}[/tex]
The rule of translation 3 units right is:
[tex]\mathbf{(x,y) \to (x - 3,y)}[/tex]
So, we have:
[tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]
Hence, the rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Courtney makes 80 % 80%80, percent of the free throws she attempts. She often stays after practice to shoot sets of 10 1010 free throws. Assume that the results of free throws are independent from each other. What are the mean and standard deviation of the number of free throws she makes in each set of 10 1010?
Answer:
Mean: 8 free throws
Standard Deviation: 1.3 free throws
Step-by-step explanation:
This is a binomial random variable, so we can use the formula [tex]ux = np[/tex], where n is the number of trials, and p is the probability. Since we know both of these values, just plug it in for the mean. [tex]ux = .8*10 = 8[/tex]
For the standard deviation, we use the formula σ = [tex]\sqrt{np(1-p)}[/tex]. Since we know what np is, we can replace those 2, giving us [tex]\sqrt{8(1-p)}[/tex]. Again, p is our probability, so this gives us our final equation of [tex]\sqrt{8(1-.8)}[/tex], which simplifies to [tex]\sqrt{8(.2)}[/tex]. Using a calculator, we get 1.264, which is 1.3 rounded to the nearest tenth.

The sum of two numbers is 56. Their product is 108. Find the larger number?
Write in solution i will mark brainliest...
Lesson: Word problems involving quadratic and rational equations
Answer: the larger number is 54
Step-by-step explanation:
x + y = 56
xy = 108
x = 56 - y
substitute the x value in equation
(56 -y) y = 108
56y - y^2 = 108
y^2 - 56y + 108 = 0
=(y - 2)(y - 54)
The two numbers are 2 and 54.
What is multiplication?Multiplication is the process of adding a number up to a given number.
Given that, the sum of the two numbers is 56 and their product is 108.
Let the numbers are x and y then,
x + y = 56 (1)
xy = 108
x = 108/y
Substitute x = 108/y into equation (1):
108/y + y = 56
108 + y² = 56y
y² -56y + 108 = 0
y² -54y -2y + 108 =0
y(y - 54) -2(y - 54) = 0
(y - 2)(y - 54) = 0
y =2 or y = 54
Now, for y = 2 the value of x is 54 and for y = 54 the value of x is 2.
Hence, the two numbers are 2 and 54.
