Mr. Jackson has a total of 12 employees. He wants to buy each employee 3 aprons that will cost $7.79 each, 1 cap that will cost $5.68, and a t-shirt that costs $13.99. How much will Mr. Jackson need to spend to purchase the items for his employees?

Answers

12/3 is 4 so multiply each by 4 so 7.79 x 4 is 31.16 5.68x4 22.72 13.99x4 55.96


31.16 + 22.72+ 55.96

Answer: $109.84

Answer: $516.48

Step-by-step explanation: Multiply 7.79 by 3 because it's 3 for each employee then multiply by 12 for each employee which equals 280.44. then 5.68 x 12 which is 68.16 for the cap. then 13.99 x 12 for the shirt which is 167.88. add 280.44, 68.16, and 167.88 to get 516.48.

Answer:

  NB = b

  NC = c

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.

_____

* 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.

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.

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

A)
(10)(2)-12) = 240

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

9514 1404 393

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.
