The area of the first, second, third, and fourth circles will be 56.72 cm², 36.3 ft², 167.33 m², and 188.6 yd² respectively.
What is a circle?It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
Then the radius and diameter are given below.
[tex]\rm r_1 = 4 \dfrac{1}{4} = \dfrac{17}{4} = 4.25 \ cm\\\\\\r_2 = \dfrac{d}{2} = \dfrac{6\frac{4}{5}}{2} = \dfrac{34}{10} = 3.4 \ ft\\\\\\r_3 = \dfrac{d}{2} = \dfrac{14.6}{2} = 7.3 \ m\\\\\\r_4 = 7\dfrac{3}{4} = \dfrac{31}{4} = 7.75 \ yd[/tex]
Then the area of the circle is given as
Area = π × r²
Then the area of the first circle will be
Area = π × r₁²
Area = 3.14 × 4.25²
Area = 56.72 square cm
Then the area of the second circle will be
Area = π × r₂²
Area = 3.14 × 3.4²
Area = 36.3 square ft
Then the area of the third circle will be
Area = π × r₃²
Area = 3.14 × 7.3²
Area = 167.33 square m
Then the area of the fourth circle will be
Area = π × r₁²
Area = 3.14 × 7.75²
Area = 188.6 square yd

there is a jar of 25 marbles. 9 of the marbles have a blue and black pattern. 6 of the marbles are purple. 10 of the marbles are green. one marble is chosen at random. what is the probability of picking to blue and black patterned marbles?
Answers
Answer:
Probability = 9/25
This is 36%
Step-by-step explanation:
To find the probability take the total number of possibilities (25 marbles--all of them) put that number on the bottom of a fraction. Then put the number of ways that outcome can happen (9 blue and black) and put that on top of the fraction.
Probability(event)
= specific/total
Probability(blu&blk)
= 9/25
If the fraction can be simplified, do that. 9/25 cannot be simplified.
If you need a percent for your answer, divide then multiply by 100.
A fraction bar is a division symbol.
9/25 means 9÷25.
9/25 = .36
Percent means "per hundred" To convert a decimal to a percent, multiply by 100
.36×100 is 36%

x = 24°
Step-by-step explanation:
angle BOC + angle BOA = 180°
angle BOC = 156°, angle BOA = x°
so x + 156° = 180°
=> x = 180° - 156° = 24°
so the measure of angle x is 24°

So first we have to know the eqation to finding the area of a semicircle, this would be:
2r x π ÷ 2 (r stands for radius)
Ok so since our diameter is 2 we need to divide that in half to find our radius which we would then get .5
And then you we would fill in the blanks and make our eqaution :
2 x 0.5 x 3.14 ÷ 2 which would give us the answer of .39

Wanda is working on her predictions for the next few days. She calculates that there is a 20% chance of rain on Monday and a 20% chance of rain on Tuesday. If she is correct, what is the probability that it will rain on at least one of these days?
Answers
Answer:
36%
Step-by-step explanation:
the complement of it raining on at least one of these days = it not raining on any day
this means that if it does not rain on at least one day, it does not rain on any day
thus,
1 - probability of it not raining at all = probability it rains at least one day
probability it doesn't rain on monday = 1- 20% = 80%
probability it doesn't rain on tuesday = 1 - 20% = 80%
probability it doesn't rain on monday AND it doesn't rain on tuesday = probability it doesn't rain at all

What is the volume of a right triangular prism?A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.
The volume of a right triangular prism = ( height× Base Area)
Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm
Actual base = 16 cm × 0.2 ft/cm = 3.2 ft
The volume of a right triangular prism = ( height× Base Area)
= [tex]5 \times 3.2\\ 16.0[/tex]
Hence, the volume of the actual ramp including the underside is 16 cubic ft.

Answer:
11) [tex]y=-(x-6)^2+4[/tex]
12) [tex]y=(x+5)^2[/tex]
Step-by-step explanation:
Vertex form of a parabola:
[tex]y=a(x-h)^2+k[/tex] where (h, k) is the vertex
Question 11From inspection of the graph, the vertex is (6, 4)
[tex]\implies y=a(x-6)^2+4[/tex]
To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.
Using point (4, 0):
[tex]\implies a(4-6)^2+4=0[/tex]
[tex]\implies a(-2)^2+4=0[/tex]
[tex]\implies 4a=-4[/tex]
[tex]\implies a=-1[/tex]
Therefore, the equation of the parabola in vertex form is:
[tex]y=-(x-6)^2+4[/tex]
Question 12From inspection of the graph, the vertex is (-5, 0)
[tex]\implies y=a(x+5)^2[/tex]
To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.
Using point (-3, 4):
[tex]\implies a(-3+5)^2=4[/tex]
[tex]\implies a(2)^2=4[/tex]
[tex]\implies 4a=4[/tex]
[tex]\implies a=1[/tex]
Therefore, the equation of the parabola in vertex form is:
[tex]y=(x+5)^2[/tex]
We need equation of the parabolas
#1
Vertex is at (6,4)One x intercept is present (4,0)
Now put that in vertex form of parabola
y=a(x-h)²+k0=a(4-6)²+44a+4=0a=-1So
equation
y=-(x-6)²+4#2
Vertex at (-5,0)So equation
y=a(x+5)²+0=a(x+5)²See the general quadratic equation having vertex (0,0) is shifted to (-5,0) means 5 units left .
So there is no a means a=
Equation remains same
y=(x+5)²What’s the volume for this problem?

Answers
Answer:
(-1, 3)
Step-by-step explanation:
x - 5y = -16 [Equation 1]
-x + 3y = 10 [Equation 2]
Adding both equations
x - x - 5y + 3y = -16 + 10-2y = -6y = 3x - 5(3) = -16x - 15 = -16x = -1
Solution : (-1, 3)
Solving for x and y,
→ (x - 5y = -16) + (-x + 3y = 10)
→ x - 5y - x +3y = -16 + 10
→ -2y = -6
→ y = -6/-2
→ [ y = 3 ]
Finding the value of x,
→ x - 5y = -16
→ x - 5(3) = -16
→ x - 15 = -16
→ x = -16 + 15
→ [ x = -1]
___________________
→ -x + 3y = 10
→ -x + 3(3) = 10
→ -x + 9 = 10
→ -x = 10 - 9
→ [ x = -1 ]
Arranging them in ordered pair,
→ (x,y)
→ (-1,3)
Thus, the solution is (-1,3).

You bought a baby fish that is 1/2 cm in length. If its length doubles every week, how long will it be in three months? Create a table to represent
Answers
Answer:
2,048 cm
Step-by-step explanation:
There are 4 weeks in a month, and the fish doubles in length every week
Let's put this into a table: (attached picture)
First we start off at 0.5 cm in week 0 (this is week 0 because you just bought the fish).
Then, the length doubles in week 1, so the fish becomes 1 cm.
In week 2, the fish's length doubles again to become 2 cm.
In week 3, the length doubles to become 4 cm.
So on, and so on until we reach a length of 2048 cm.
Therefore, after 3 months the fish's length will be 2,048 cm.
