What is the area of the circle with a diameter of 14 cm?
Answer:
49π
Step-by-step explanation:
The area for the formula of a circle is πr^2, where r is for radius. A radius is half of the diameter, which in this case is 14. 14/2 = 7, so the radius is 7. π(7)^2 = 49π.
What is the value of x?
Answer:
the answer is 85°
180° - ( 52° + 43°)
= 180° - 95°
= 85°

Need help I’m getting stuck on this problem
Answer:
y is already isolated in the top equation
x = 4
y = 12
(4,12)
Step-by-step explanation:
y is already isolated in the top equation
plug y = 3x into bottom equation
5x + 2y = 44
5x +2(3x) = 44
5x + 6x = 44
11x = 44
x = 4
plug x = 4 into y = 3x
y = 3(4)
y = 12
In the expression 3x + 5x – 3y + 5, which terms are “like terms”?
A. 3x and 3y
B. x and 5
C. 3x and 5x
D. all terms
Answer: C
Step-by-step explanation: 3x and 5x both have x
What is the area to this figure ?
Answer:
Paralleogram Area = 98 cm²
Rectangle Area = 147 cm²
Total Area of Composite Figure = 245 cm²
Step-by-step explanation:
To find the area of paralleogram you have to take the odd part out and put it on the other side to make a rectangle. Then find the area of that rectangle. 7 * 14 = 98²
After that, Find the area of The regular rectangle. 7 * 21 = 147²
Then, do 98² + 147² = 245²
Thats how you get the answer of 245 cm²

3(x+2)-4=4(x-3)
Answer:
-x= -14
Step-by-step explanation:
3(x+2)-4=4(x-3)
3(x+2)=3x+6
3x+6-4=3x+2
3x+2=4(x-3)
4(x-3)=4x-12
3x+2=4x-12
3x-4x=-1x
-12-2=-14
-x=-14
Answer:
Step-by-step explanation:
3(x+2)-4=4(x-3)
3x+6-4=4x-12
3x+2=4x-12
-3x. -3x
2=1x-12
+12. +12
14=1x
/1. /1
14=x
Then we put it back in the problem.
3(x+2)-4=4(x-3)
3(14+2)-4=4(14-3)
3(16)-4=4(11)
48-4=44
44=44

The ratio of fish to turtles in a pond is
20:3. There are 80 fish in the pond.
How many turtles are in the pond?
A 10
14
C 12
D 16
Answer:
C : 12
Step-by-step explanation:
Answer:
12 turtles
Step-by-step explanation:
First, if the ratio of fish to turtles is 20:3 and there are 80 fish, then we know that you have to divide 80 by 4 to get the answer 20. However, to find out how many turtles there are you need to do the opposite and multiply instead of dividing. So you do 3 x 4, which get you your answer.
Hope this helps!

Answer:
B. If A plant is bamboo, then it is a grass. If a plant is a grass, then it is a graminoid. A plant is bamboo. Therefore, the plant is a graminoid.
Step-by-step explanation:
A syllogism is a sequential implication:
If p then q, and If q then r ⇒ p therefore r.
__
To choose the example, you need to find the elements of each implication and see if they match this pattern.
A: p ⇒ q; q ⇒ r; r ∴ p . . . . not a syllogism
B: p ⇒ q; q ⇒ r; p ∴ r . . . . the syllogism we're looking for
C: p ⇒ q; q ∴ p . . . . not a syllogism
D: p ⇒ q; p ∴ q . . . . not a syllogism

3. Ana's bedroom measures 8-feet by 12-feet. She
wants to set up a corner of her room for arts and
crafts and wants to use one fourth of the dimensions
of her room for it. What will be the area of her arts
and crafts corner?
Please help me! Show work please. Sorry:(
If she wants one fourth of the dimensions of the room for the corner, that means the area will be 1/16 (one fourth squared) of the whole bedroom. The area of the whole bedroom is 8 x 12 = 96. The area of the corner would be 96 / 16 = 6 sq ft.
Or you can do (one fourth of 8) x (one fourth of 12) = 2 x 3 = 6 sq ft.

Which of the equations below could be the equation of this parabola?
A. x=4y^2
B. y=4x^2
C. y=-4x^2
D. x=-4x^2
Answer:
C. y=-4x^2
Step-by-step explanation:
To eliminate a and b the parabola is a negative and neither one of those are negative. When the parabola is facing down its a negative.
To eliminate D the parabola is going down on the y-axis so it cant be d.
Which leaves us with C.
So the answer is indeed C.

Solve [tex]\sqrt{384}[/tex] without going into decimals.
(Answer is below)
Let's solve this step-by-step.
1. Prime factorization of 384.
[tex]=\sqrt{2^7\times3}[/tex]
2. Apply the exponent rule. (Formula: [tex]a^b^+^c=a^b\times a^c[/tex])
[tex]=\sqrt{2^6\times2\times2\times3}[/tex]
3. Apply the radical rule. (Formula: [tex]\sqrt{ab} =\sqrt{a}\sqrt{b}[/tex] or [tex]a\geq 0,b\geq 0[/tex])
[tex]=\sqrt{2^6} \sqrt{2\times3}[/tex]
3a. Solve 2 to the 6th power.
[tex]\sqrt{2\times2\times2\times2\times2\times2} =8[/tex]
4. Multiply 2 by 3. (Note: Put the 8 in your final answer)
[tex]\sqrt{2\times3} =8\sqrt{6}[/tex]
Your answer is: [tex]8\sqrt{6}[/tex]
