Answer OPTION C
AT LEAST... means that she needs 80% and more
Meaning its must be equal to 80% or greater than 80%
Average has to do with Mean.
Her mean would have to be
The sum of the 3 last algebra tests plus the unknown one she's supposed to have to complete 80%
So

Ify is floating freely in outer space. The gravitational forces pulling on her body are negligible except for the forces from a nearby asteroid (a) the nearest planet (p) and the nearest star (s) The asteroid, planet, star, and Ify all lie in the same plane.
a= (2,4)
p=(-1.-3)
s=(8,2)
Answer:
The magnitude of the net gravitational force acting on Ify is 9.1 newtons.
Ify is getting pulled in a direction of 6.2 radians.
Step-by-step explanation:
The vector g = (9,-1) describes the net gravitational force acting on Ify.
We can find the magnitude of g, using the Pythagorean theorem.
3x-8y=24
y=x-8
Please show
work
Answer:
3x - 8y = 24 --------(1)
y = x - 8 ---------(2)
substitute y in (1)
3x - 8( x - 8) = 24
3x - 8x + 64 = 24
-5x = 24 - 64
-5x = -40
5x = 40
x= 8
substitute x in (2)
y = 2 - 8
y = - 6
Answer:
x = 8, and y = 0
Step-by-step explanation:
We can solve this by taking y as (x-8), as it states there.
Since y is equal to x-8, we can rearrange the system of equations into one single equation.
We can multiply y by 8, as it shows in the first equation, which is something like 8x-64.
Since it is a negative 8 being multiplied by y, it would be the inverse of 8x-64, which is -8x+64.
We can now organize our equation here.
3x - 8x + 64 = 24.
We can use subtraction property of equality by subtracing 64 from both sides to get rid of it.
We will get something like:
3x - 8x + 64 - 64 = 24 - 64.
Simplify by solving like terms like the x value and the integers.
-5x = -40
Divide both sides with division property of equality:
-5/5x = -40/5
x = 8
We can then plug the 8 back into x, lets use the second equation because I'm lazy and it looks the easiest to solve for.
y = (8) - 8
y = 0
Therefore, x = 8, and y = 0.
Janet is comparing prices of bottled drinks. She finds one bottle of water that costs $1.92 and contains 12 ounces. She then finds one bottle of soda that costs $2.40 and contains 16 ounces. Which bottle costs less per ounce?
it a short answer response
Answer:
1 ounces of water= $0.16
1 ounces of soda= $0.15
Water costs $0.16 per ounces while soda costs $0.15 per ounces which means soda costs less than water per ounces.

If a histogram is right skewed, which will be greater the mean or the median? Type a single word answer in the space
provided, for example if the answer is mode, type mode.
Answer:
Mean is greater
Step-by-step explanation:
For a skewed distribution, then the tail is longer to one side from the center than to the other. In a right skewed distribution, the tail is longer to the right.
When a distribution is skewed, the mean will be closer to the tail Than the median. Therefore. For a right skewed histogram, the mean is closer to the tail of the histogram and hence closer to the right. Once this happens, values closer to the right of a distribution are higher (number line). Thus the mean will be greater than the median.

If ABCD is a square, and the area covered by the blue equilateral triangle is 49√3cm², what will be the area covered by the yellow region (in cm²)?
a. 139
b. 98
c.42
d. 154
no spam answers please!
49√3 = √3/4 a²
49×4 = a²
a = 7×2
a = 14 cm
Side of equilateral triangle = Side of square ABCD = 14cm
Area of square ABCD = a²
A = 14×14
A = 196 cm²
Now diameter of circle = side of square = 14cm
Radius = D/2 = 7 Cm
There are two half circle in the square = one whole circle
Area of circle = πr²
A = 3.14 ×7 ×7
A = 153.86
Area of yellow region = Area of square - Area of circle
Area of yellow region = 196 - 153.86 = 42.14 Cm²
The area covered by the yellow region (in cm²) in the given diagram is 42cm². The correct option is c.42
From the question, the area of the blue equilateral triangle in the given diagram is 49√3cm².
The area of an equilateral triangle can be calculated by finding half the product of the square of a side (all sides are equal in an equilateral triangle) and sin 60° (each interior angle of an equilateral triangle is 60°)
Hence, the area of the blue triangle is given by
[tex]A = \frac{1}{2}/AB/^{2}sin60\°[/tex]
Where A is the area
Therefore,
[tex]49\sqrt{3} = \frac{1}{2}/AB/^{2}sin60\°\\2 \times 49\sqrt{3} = /AB/^{2} \times \frac{\sqrt{3} }{2}[/tex]
[tex]2 \times2 \times 49\sqrt{3} = /AB/^{2} \times \sqrt{3}[/tex]
[tex]196 \sqrt{3} = /AB/^{2} \times \sqrt{3}[/tex]
∴ [tex]/AB/^{2} = \frac{196 \sqrt{3} }{\sqrt{3} }[/tex]
[tex]/AB/^{2} = 196[/tex]
∴ [tex]/AB/ = \sqrt{196}[/tex]
[tex]/AB/ = 14cm[/tex]
Hence, the length of a side of the square is 14 cm and the diameter of the circle is also 14 cm (since the length of a side of the square cuts the circle into equal halves, hence it is the diameter)
Area covered by the yellow region = Area of the square - ( sum of the areas of the two semicircles)
Sum of the areas of the two semicircles = Area of one circle
Area of a circle is given by the formula
[tex]A = \pi r^{2}[/tex]
But r = d/2
where r is radius and d is diameter
∴ r = 14/2 cm
r = 7cm
Hence
Area of the circle = [tex]\pi \times 7^{2}[/tex]
A = [tex]49\pi[/tex]
Taking π = 22/7
∴ A = [tex]49 \times \frac{22}{7}[/tex]
A = 154cm²
This is the sum of areas of the two semicircles
Now, for the area of the square
Area of the square = /AB/²
∴ Area of the square = 196 cm²
Now, as stated earlier,
Area covered by the yellow region = Area of the square - ( sum of the areas of the two semicircles)
∴ Area covered by the yellow region = 196 cm² - 154cm²
Area covered by the yellow region = 42cm²
Hence, the area covered by the yellow region (in cm²) in the given diagram is 42cm²
The correct option is c.42

Tan?cos? Sin? What is the m
Answer:
45º
Step-by-step explanation:
Since we know the relatiionship of a 45-45-90 degree triangle, we can go two ways. Either we can use this to find CA and get the tangent of (6/6) or we can go straight to it. The hypotenuse in a 45-45-90 is always 6√2 and we know it is a right triangle so we can confirm this. So, measure of angle B is 45º.

PLEASE HELP!!! Classify each real number. List all the subsets in which the number belongs.
Answer:
9^3 is Natural, Whole, Integer, and Rational
7/4 is Rational
√3 is Irrational
0 is Whole, Integer, and Rational
Thinking Process:
Alright, to start, with 9^3, it equal 729. This is a natural, whole, integer, and rational number. It is a natural number because it follows the counting (1, 2, 3...etc). Because of this, it is also part of all of the other rational categories as well.
With the next one, 7/4, this equals 1.75. It is not a natural, whole, or integer number because it is a decimal. However, it is rational, because it is still definite.
Next, with √3, this equals 1.73205.... It is irrational because it is not definite as it is a sequence of numbers that go on forever, being unpredictable in nature.
Last is 0, it is not a natural number because it does not follow the counting (1, 3, 3...etc). But it is whole because it follows the counting (0, 1, 2, 3...etc). This is along with it being an integer and rational because of this.

I believe your answer is:
The square root of 5 ([tex]\sqrt{5}[/tex]) is irrational.

Here’s why:
A rational number is a number that can be rewritten as a fraction of two integers with a nonzero denominator. Rational numbers include integers, fractions, terminating decimal, or repeating decimals.A square root that is perfect would be rational. A non-perfect square root is irrational.⸻⸻⸻⸻
Since the square root of 5 is not a perfect square, it would be irrational.
