Answer:
x=1.25 and y=-5.5
Step-by-step explanation:
2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

If the diameter of a circle is 8, then what is its area and its circumference?
Answer:
A≈50.27
Diameter = 8
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·82≈50.26548
Answer:
I think it would be 50.24
Step-by-step explanation:
Here's what I did:
1. Diameter = 8 so radius = 4
2. 4 to the second power is 16
3. 16 × 3.14 = 50.24
I'm not sure if what I did is correct, but I hope this helps! :)

What fraction is represented by point A on the number line shown?
What is the rule for dividing a fraction explain.
Answer:
When students see a number that ends in an even digit, they should know the number can be divided into two evenly. However, numbers that end in odd digits can be divided by two, they'll just have a remainder or decimal.

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
81.12 cm²
Step-by-step explanation:
The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.
(3.14 * 4²)/2 + (14 * 8)/2 (Work the operations in parentheses first.)
(3.14 * 16)/2 + 112/2
50.24/2 + 112/2 (Divide 50.24 by 2. Do the same for 112.)
25.12 + 56 (Add 25.12 & 56.)
81.12 cm²
The area of the figure is 81.12 cm².

Kalani has these monthly liabilities: rent $879, car payment $315, credit card payment $102. She has an annual
income of $96,448. What is her debt-to-Income ratio, expressed as a percent?
Answer:
1.34%
Step-by-step explanation:
Given data
Rent =$879
Car payment =$315
Credit card payment= $102
Annual Income= $96,448
In all the debt is
=879+315+102
=$1296
Hence the debt to income ratio is
=1296/96,448
=0.0134
As percent
=0.0134*100
=1.34%

To compute the square of the length of a sloped side, you need to sum the squares of the rise and the run. For example, the square of the length of 'a' in triangle F is ...
a² = rise² + run² = 1² +2² = 1 +4 = 5
__
Additional comment
When computing the slopes of the various triangle sides, you need to pay attention to the sign of the "rise" for a positive "run."
For the distance purpose here, the rise and run are squared, so their signs are irrelevant. You can treat them all as positive numbers.

Can someone please help me find the area.
Answer:
51 ft²
Step-by-step explanation:
The figure is composed of two different triangles (triangle 1 and 2) and a rectangle
Area of the composite figure = area of triangle 1 + area of triangle 2 + area of rectangle
✔️Area of triangle 1 = ½*bh
b = 3 ft
h = 2 ft
Area of triangle 1 = ½*3*2 = 3 ft²
✔️Area of triangle 2 = ½bh
b = 3 ft
h = 3 ft
Area of triangle 2 = ½*3*3 = 4.5 ft²
✔️Area of rectangle = L*W
L = 3 + 8 = 11 ft
W = 4 ft
Area of rectangle = 11*4 = 44 ft²
✅Area of the composite figure = 3 + 4 + 44
= 51 ft²

Thousands of people are going to a Grateful dead concert in Pauley Pavillion at UCLA. They park their the foot cars on several of the long streets near the arena. There are no lines to tell the drivers where to park, so they park at random locations, and end up leaving spacings between the cars that are independent and uniform on .0; 10/. In the long run, what fraction of the street is covered with cars
This question is incomplete, the complete question is;
Thousands of people are going to a Grateful dead concert in Pauley Pavilion at UCLA. They park their 10 foot cars on several of the long streets near the arena. There are no lines to tell the drivers where to park, so they park at random locations, and end up leaving spacings between the cars that are independent and uniform on ( 0, 10 ). In the long run, what fraction of the street is covered with cars?.
Answer:
in the long run, the fraction of street that will be covered with cars is 0.6667
Step-by-step explanation:
given the data in the question;
the gaps between two cars follows uniformly ) 0, 10 )
therefore in the long run, average gap will be;
⇒ (0 + 10) / 2 = 10 / 2 = 5 feet
meaning that, in the long run a single car will occupy;
⇒ length of car + gap
⇒ 10 + 5 = 15 feet
∴ the fraction of road covered with cars will be;
⇒ length of car / space or length of road occupied by one car
⇒ 10 / 15
⇒ 0.6667
Therefore, in the long run, the fraction of street that will be covered with cars is 0.6667
