The correct situation for the given condition are as follows:
C) Both proposed placements will light the same sized area.
F) Dylan's proposed placement will light exactly half of the yard.
What is Area of Triangle?
The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
The area of a triangle = (base x height) / 2
and,
both lights illuminate the same base and height = (60 x 38) / 2
= 1,140 sq ft
Both Dylan's and Nikki's proposed placement will lit exactly half of the yard.
The yard's total area = 60 x 38 = 2,280 sq ft,
which is twice the area lit by the lights.
Thus, The correct situation for the given condition are as follows:
C) Both proposed placements will light the same sized area.
F) Dylan's proposed placement will light exactly half of the yard.

1. In the following exercises, translate into an equation and solve
a. Distance Avril rode her bike a total of 18 miles, from home to the library and then to the beach. The distance from Avril’s house to the library is 7 miles. What is the distance from the library to the beach?
Answer:
11 miles
Step-by-step explanation:
The length of the route is the sum of the lengths of the parts of the route.
__
Let b represent the distance to the beach from the library.
total distance = (home to library) +(library to beach)
18 miles = 7 miles + b
11 miles = b . . . . . . . . . . subtract 7 miles from both sides of the equation
The distance from the library to the beach is 11 miles.

The answer will be 4-1pleaseIf C=m+1C=m+1 and B=m+5,B=m+5, find an expression that equals 2C+3B2C+3B in standard form.
The value of the expression 2C+3B is 5m + 7
How to evaluate the expression?The given parameters are:
C = m + 1
B = m + 5
To evaluate the expression 2C+3B;
We substitute C = m + 1 and B = m + 5
So, we have:
2C+3B = 2 * (m + 1) + 3 * (m + 5)
Expand
2C+3B = 2m + 2 + 3m + 15
Evaluate the like terms
2C+3B = 5m + 7
Hence, the value of the expression 2C+3B is 5m + 7

can someone find the radius and center point of x^2+y^2-16x+2y+56=0 (general form)
Answer:
Center is [tex](8,-1)[/tex]
Radius is [tex]3[/tex]
Step-by-step explanation:
To convert from a general form equation to a standard form equation, we must complete the square for each variable to simplify. Make sure to rearrange the equation to complete the square more easily:
[tex]x^2+y^2-16x+2y+56=0\\\\x^2-16x+56+y^2+2y=0\\\\x^2-16x+56(+8)+y^2+2y(+1)=0+8+1\\\\x^2-16x+64+y^2+2y+1=9\\\\(x^2-16x+64)+(y^2+2y+1)=9\\\\(x-8)^2+(y+1)^2=9[/tex]
Since the equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex], our circle will have a center of [tex](h,k)\rightarrow(8,-1)[/tex] and a radius of [tex]r^2=9\rightarrow r=3[/tex].
calculate mpg for w=1000,w=2000;calculate weight when mpg=30
Based on the information above, the car with 1,000 pounds more will only go 1,194 miles, and the one with 2,000 pounds more will only go 1,188 miles.
What does MPG stand for?MPG stands for miles per gallon, and refers to the distance in miles a vehicle travels for each gallon of fuel in its tank.
In general, a car consumes about 1,200 miles per gallon. However, when you add load to it, its fuel consumption is higher because it requires more force to move.
Additionally, some studies state that for every 1,000 pounds of weight added to the car, it will yield 0.5% less. So if the car has 1,000 more pounds, it's not going to go 1,200 miles per gallon, it's going to go 1,194 miles.
On the other hand, if 2,000 pounds of weight were added, the fuel economy would be 1% less, that is, it would travel 1,188 miles per gallon.

The graph represents a relation provided R = {(5, 1), (1, –2), (0, –1), (–3, 2)}
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
We have a relation:
R = {(5, 1), (1, –2), (0, –1), (–3, 2)}
We can represent it on a coordinate plane as (x, y)
After plotting on a coordinate plane we will get a graph of a relation
R = {(5, 1), (1, –2), (0, –1), (–3, 2)}

Sonya's heart rate was 76 beats per minute.
She ran a mile on her treadmill and checked
her heart rate again. This time, her heart rate
was 133 beats per minute. What was the
percent increase in Sonya's heart rate?
Answer:
75 percent
Step-by-step explanation:
To find percent increase, do (final-initial/initial) * 100.
This would be 133-76/76 * 100, meaning you get a 75 percent increase.
The percent increase is 75 %.
What is Percent increase?The ratio of the increased value to the original value, multiplied by 100, is the percentage increase formula. It is outlined as a percentage. Anything's value will increase if it is valued more, so will its proportion.
Given:
Sonya's heart rate was 76 beats per minute.
After running, heart beat rate= 133 beats per minute.
So, percent increase
= (133- 76)/ 76 x 100
= 0.75 x 100
= 75%
Hence, the percent increase is 75 %.

Answer:
220
Step-by-step explanation:
Now, I'm not sure if 220 is correct, but I'll explain my reasoning.
We know three angles of a triangle add up to 180 degrees.
So, the smaller triangle has 70 degrees and a and b variables. By virtue, a + b + 70 = 180.
So, a + b = 110.
Likewise, when you look at the whole triangle, 70 degrees is also one of the angles while c and d are unknown.
So, c + d + 70 = 180.
This means c + d = 110.
So, (a + b ) + (c + d ) =
110 + 110 =
220 degrees.
I hope this helps!
Answer:
110
Step-by-step explanation:
a + b + c + d = 110
