Geometry
Answers
Answer:
19 feets
Step-by-step explanation:
Given that , the radius of the circle is 3 feet . We need to find the circumference.
We know that the circumference of circle is 2πr . So ,=> C = 2 π r
=> C = 2 × 22/7 × 3ft
=> C = 18.84 ≈ 19 ft
Hence the circumference of the circle is 19 feet.Answer:
B
Step-by-step explanation:
circumference = 2πr
3.4x 2 x 3 = 18.84

Radius is the distance halfway across the circle so in this case, r=9
Now just plug the radius value into the equation:
A = π(9)^2 —> A = π(81) —> A = 254.34 —> round to the nearest tenth A = 254.3
**keep in mind we use 3.14 for π**

Find the area of the trapezoid 2 2 2 2 4
Answers
Answer:
It is 10.
Step-by-step explanation:
If we just find the area for each section and add them all up it would equal 10. The first triangle, 2x2=4 then divide that by 2 will equal you 2. Then the square is just 2x2 =4. Then the last triangle, 2x4=8 then divide that by 2 = 4. 2+4+4=10.
Answer:
Correct answer is (10)
Step-by-step explanation:
since 2 triangles come together to form a square\rectangle
length * width = Area
we can find both areas of the triangles:
left triangle: 2*2 = 4 --> 4 devided in half = 2
square area = 4
right side triangle: 2*4 = 8 ---> devided in half = 4
______________________________________
next add up all the measurements for each piece:
left triangle + middle square + right side triangle = area
(2+4+4 = 10)

Hong made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was 10.40 If the beads cost 2.50 for each necklace, how much did each pendant cost?
Answers
b=2x 2.50
Now using substitution method replace b in first equation with value of second equation basically combing the two equations into one do you end up with one variable to solve .
2 x 2.50 +p =10.40
5 + p=10.40
P=$5.40
b =$5.00
The answer is EACH pendant cost $2.70
(You have to divide 5.40 by two )
A probability model includes P(red) = 27 2 7 and P(blue) = 314 3 14 . Which of the following probabilities could complete the model? Select all that apply. A.

P(green) = 37 3 7 , P(yellow) = 114 1 14
Answers
Answer:
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]P(Red) = \frac{2}{7}[/tex]
[tex]P(Blue) = \frac{3}{14}[/tex]
Required
Which completes the model
Let the remaining probability be x.
Such that:
[tex]P(Red) + P(Blue) + x = 1[/tex]
Make x the subject
[tex]x = 1 - P(Red) - P(Blue)[/tex]
So, we have:
[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]
Solve
[tex]x = \frac{14 - 4 - 3}{14}[/tex]
[tex]x = \frac{7}{14}[/tex]
[tex]x = \frac{1}{2}[/tex]
This mean that the remaining model must add up to 1/2
[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]
This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
Other options are also false
