Answer:
-4
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-16 + 8) / (-8 + 10)
-8 / 2

A tree stands on horizontal ground. The angle of elevation of the top of the tree from a point 50 m away from the base of the tree is 11.3°. Calculate the height of the tree.
Answer: 9.99m
Step-by-step explanation:
So you have a right triangle, and from that you should be able to get all three angles because you have the 90 degree angle, the 11.3 angle, and the mystery angle, so you do the equation 180 (the total amount of degrees for a triangle) - 90 - 11.3, which gives you 78.7, then calculate the rest from there. (You can calculate from only having one side and three angles)

Answer:
B x = 3 or -12
Step-by-step explanation:
(btw this / is a fraction sign and this ^ is the power of sign)
Let's solve your equation step-by-step.
x^2+9x−36=0
For this equation: a=1, b=9, c=-36
1x^2+9x+−36=0
Step 1: Use quadratic formula with a=1, b=9, c=-36.
x= −b±√b^2−4ac/2a
x= −(9)±√(9)2−4(1)(−36)/2(1)
x= −9±√225/2

At a cot of $8 per pound, how many ounce of rice flour can be boight for $2. 80?
The total rice flour is 5.6 ounces can be bought for $2.80 at that cost.
Rice Flour Cost CalculationThere are 16 ounces in a pound. So $8/16 ounces = $0.50 per ounce. Therefore, $2.80/$0.50 = 5.6 ounces of rice flour can be bought for $2.80 at that cost.
The calculation was determining how many ounces of rice flour can be bought for $2.80 at a cost of $8 per pound. It converts the cost per pound to cost per ounce and then divides the total cost by the cost per ounce to find the number of ounces that can be bought.
This type of calculation can be applied in daily life when comparing prices of different units of measurement (e.g. pounds to ounces) or when trying to stay within a budget when purchasing items. It can be used to compare prices and help make informed decisions about what to buy.

is 220 pounds per square inch, at what pressure, in pounds per square inch, will the alarm bell ring?
Answer:
The alarm bell will ring at 473 psi.
Step-by-step explanation:
To answer this, find 215% of 220 pounds per square inch:
Convert the percentage 215% to its decimal fraction equivalent, 2.15, and then multiply 220 pounds per square inch by it:
2.15(220 psi) = 473 psi

The equation of the line passing through the point (-1,2) with slope m is y = mx + m-2. This is a general equation of the line and we can find different equations by putting different values of m.
We know that when a point and slope of the equation are given, an equation can be written as
\(\frac{y-y_{1} }{x - x_{1} } =m\)
which is known as the slope-point form
where m is the slope of the equation
y1 is the y coordinate of the given point
x1 is the x coordinate of the given point
In the given question, y1 = 2 and x1 = -1
Substituting the value of coordinates in the slope point equation, we get
\(\frac{y-2}{x-(-1)} = m\)
\(\frac{y-2}{x+1}=m\)
y-2 = mx + m

What type of ANOVA is used when there is only one type of treatment or grouping factor with more than two levels
When there is only one type of treatment or grouping factor with more than two levels, a one-way ANOVA is used. This type of ANOVA compares the means of multiple groups to determine if there is a significant difference between them. The factor, or independent variable, is the single grouping factor with multiple levels. The dependent variable is the measure of interest that is being compared across the groups. The one-way ANOVA is useful when trying to determine if there is a significant difference in the means of multiple groups, but it does not provide information on which specific groups are significantly different from each other. Pairwise comparisons or post-hoc tests can be used to further analyze the differences between groups.
Hi! The type of ANOVA used when there is only one type of treatment or grouping factor with more than two levels is called One-way ANOVA. One-way ANOVA is a statistical method used to test the null hypothesis that there are no differences between the means of the different groups, considering only one independent variable, the grouping factor. It helps in determining if the factor has a significant effect on the dependent variable by comparing the variance within groups and the variance between groups.

kadeem and quinn both drive 25 miles. Kadeem drives at a constant speed of 50 miles an hour. Quinn drives at a constant speed of 75 miles an hour. Who takes longer to drive the 25 miles? How much loner?
Answer:
I believe it is Kadeem who takes longer by 10 minutes.
Step-by-step explanation:
A person whose speed is slow will take longer to reach so Kadeem takes longer by 0.5 hours.
Given that,
Kadeem and Quinn both drive 25 miles.
Kadeem drives at a constant speed of 50 miles an hour.
Quinn drives at a constant speed of 75 miles an hour.
To determine who takes longer to drive the 25 miles.
Distance is defined as the object traveling at a particular speed in time from one point to another.
Here,
Time is taken by Kadeem to reach 25 miles with a speed of 25 miles per hour
= 25 / 50 = 0.5 hour
Time is taken by Quinn to reach 25 miles with a speed of 75 miles per hour,
= 25 / 75 = 0.34 hour

length of a rectangle is 6 feet longer than the width. If the width of the rectangle is w feet long, which of the following expressions represents the
meter of the rectangle?
Answer:
4w + 12
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Width of the rectangle = w feet
Length of the rectangle = (w + 6) feet
Perimeter of a rectangle = 2(length + width)
= 2{(w+6) + w}
= 2(w + 6 + w)
= 2(2w + 6)
= 4w + 12
Perimeter of a rectangle = (4w + 12) feet

In ACDE, M/C = (x-4)°, m/D = (9x + 4)°, and m/E = (2x + 12)°.
Find m/D.
Thus, in ΔCDE the m/∠D = 130⁰, which can be calculated using angle sum property of triangle.
What is triangle?Triangle is derived from the Latin word triangulus, which means "three-cornered" or "having three angles," and is composed of the roots tri-, "three," and angulus, "angle or corner." Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The total of the triangle's three angles equals 180 degrees.
Given that: In ΔCDE
m/∠C = (x-4)°
m/∠D = (9x + 4)°
m/∠E = (2x + 12)°
Now, to find m/∠D
So, We know that sum of internal angles of a triangle is equal to 180⁰ .Here, we are given a ΔCDE and all its three internal angles.
Putting the sum of all three equal to 180⁰:
∠C + ∠D + ∠E = 180⁰(x-4)°+ (9x + 4)°+ (2x + 12)°
= 180⁰12x +12
= 180⁰x +1 = 15⁰
x = 14⁰
Thus, Putting value of x in m/∠D = (9x + 4)°.
m/∠D = (9 × 14 +4)⁰
m/∠D = 130⁰

You are planning to rent a condo. Your monthly rent will be $750, and your renters insurance will be $1,800 per year.
What is the adjusted monthly cost for renting this condo?
The adjusted monthly cost for renting this condo is $900.
How to calculate the adjusted monthly cost for renting the condo?To calculate the adjusted monthly cost for renting the condo, we need to convert the annual renters insurance premium to a monthly premium by dividing it by 12.
Monthly cost for renters insurance = $1,800 / 12 = $150
Adding the monthly rent and monthly renters insurance cost, we get:
Monthly cost for renters insurance = $1,800 / 12 = $150
Adjusted monthly cost = $750 + $150 = $900

im has a health insurance policy with the following provisions: $300 deductible, $50 copay, and an 70/30 coinsurance. If Jim has an accident that costs $3,000 in medical expenses, how much does will he have to pay out-of-pocket? $350 $795 O $1,145 O $2,675
Jim will have to pay $795 out-of-pocket if he has an accident that costs $3,000 in medical expenses. Option b is correct.
Let’s calculate the amount Jim has to pay out-of-pocket. Jim has an accident that costs $3,000 in medical expenses, so the total cost is $3000.Jim’s health insurance policy has the following provisions:
Deductible = $300
Co-pay = $50
Coinsurance = 70/30
Since the coinsurance provision is 70/30, this means that Jim's insurance will pay 70% of the remaining expenses after deductibles and co-pays and Jim will pay the remaining 30%.
Thus, Jim will pay 30% of the remaining expenses after deductibles and co-pays. Out of the total $3000 medical expenses, Jim has to pay the first $300 (deductible).
The remaining amount is $3000 – $300 = $2700.
He has a copay of $50, thus reducing the remaining amount to $2650.
So, Jim has to pay 30% of $2650 which is equal to:
$2650 × 0.3 = $795
Therefore, Jim has to pay out-of-pocket $795. The correct option is option B.
