Answer: The answer is D

I really do hope this is the answer but I am really sorry if this is wrong

Step-by-step explanation:

the main equation would be

210+3x>288

first I divided 210 by 3 to see how many mugs he has sold first. Then I got an answer of 70 mugs sold. after that i subtracted 210 from 288 and got 78. After this I divided 78 by 3 to get a count of how many mugs Ronny needs to sell. so The total amount of mugs Ronny needs to sell to reach his goal of 288$ is 96. But he has already sold 70 so he needs to sell 26 more mugs.

Which products are correct?
A)
(10)(2)-12) = 240
B)
(-9)(-8)(2) = 144
(-10)(7)(3) = -210
D)
(-5)(-3)(6) = -90
E)
(-1)(-1)(-1)(-1) = 1

Answer:

NB = b

NC = c

Step-by-step explanation:

A "quick and dirty" proof could be this:

M is the midpoint of AN; M is the midpoint of BC . . . . givenABNC is a parallelogram . . . . diagonals AN and BC have the same midpoint (M)*NB = AC = b; NC = AB = c . . . . opposite sides of a parallelogram are congruent.

More formally, we might prove it like this:

MC = MB . . . . definition of medianMA = MN, AC = b, AB = c . . . . given∠CMA ≅ ∠BMN . . . . vertical angles are congruentΔCMA ≅ ΔBMN . . . . SAS congruence postulateAC ≅ NB . . . . CPCTCNB = b . . . . substitution property of equality/congruence∠CMN ≅ ∠ BMA . . . . vertical angles are congruentΔCMN ≅ ΔBMA . . . . SAS congruence postulateAB ≅ NC . . . . CPCTCNC = c . . . . substitution property of equality

* The proof is "dirty" only in that the theorem "if the midpoints of the diagonals of a quadrilateral are coincident, then that quadrilateral is a parallelogram" is not one usually available to cite in proofs. The "more formal" proof here essentially proves that the quadrilateral is a parallelogram.

This is also with the other one sorry I just don't get it:
-8x = -64
50 = -(1/8)p
-90 = 8 + y
if someone can help me please help me.

Answers

the first one would be 8 becuase 8 times -8 would be -64. i don’t know the second one but the last one is -82 becuase 8 plus -82 equals -90.

Answer:

x = 8

p = -400

y = -98

Step-by-step explanation

-8x = -64

Divide both sides by -8

x = 8

50 = -(1/8)p

Divide both sides by -(1/8)

p = 50/-(1/8)

p = -400

-90 = 8+y

Subtract 8 from each side

y = -98

B.
The ratio of a circle's diameter to its circumference is equal to π.

C.
The sum of a circle's diameter and its circumference is equal to π.

D.
The difference between a circle's circumference and its diameter is equal to π.

Answers

The Answer is d because to find circumference you multiply diameter by pi/3.14

B. The ratio of a circle's diameter to its circumference is equal to π.

What are the circumference and diameter of a circle?

The circumference of a circle is the distance around the circle which is 2πr.

The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.

We know the diameter of a circle is 2r and the circumference of a circle is 2πr.

∴ The correct statement about the relationship between the diameter and circumference of a circle is The ratio of a circle's diameter to its circumference is equal to π.

As diameter : circumference = 2πr : 2r.

So, the equations describe the same line. Because every point on the line is a solution of the equation, and thus of the system, there are infinitely many solutions.

A cyclist accelerates from rest at a rate of 7.0 m/s2. How long will it take the cyclist to reach a speed of 18 m/s?
(Its really a subject for science, but I didn't want to put the wrong thing)

Answers

Answer:

2 4/7 seconds

Step-by-step explanation:

Velocity and (constant) acceleration are related by ...

v = at

Filling in the numbers, we can solve for t:

18 m/s = (7 m/s²)·t

t = (18 m/s)/(7 m/s²) = (18/7) s = 2 4/7 s

It takes the cyclist 2 4/7 seconds (about 2.57 seconds) to reach 18 m/s.

Problems involving position and its derivatives can reasonably be posted in the Math section. When energy or mass get involved, the Physics section is a better place. The relevant formulas for those are not always covered in algebra classes.
