chuck's coin box contains only pennies and nickels. if he jas 66 coins worth 2.38. how many of each type of coin foes he have​
schepotkina [342]

Answer:

You have 43 nickles and 23 pennies

Step-by-step explanation:

43 x 5 = 2.15

you have 2.38 total in 66 coins

so 2.38 - 2.15 = 0.23

that will leave you with 23 pennies

23 pennies plus 43 nickles = 2.38

0.23 + 2.15 = 2.38

Z = ma for a please help
il63 [147K]

Answer:

Z = Ma = ba

You made a typo. One of those = signs should either  

be a + and a -.  Here are all possibilities:

1.     Z+Ma = ba, solve for a

     Ma-Ba = -Z

    a(M-B) = -Z

         a = -Z/(M-B)

2.        Z = Ma+ba, solve for a

     Ma+ba = Z

    a(M+b) = Z

         a = Z/(M+b)  

3.     Z-Ma = ba, solve for a

         Z = Ma+ba

     Ma+ba = Z

    a(M+b) = Z

         a = Z/(M+b)

4.       Z = Ma-ba, solve for a

     Ma-ba = Z

    a(M-b) = Z

         a = Z/(M-b)

A water balloon is thrown out of a window 96 feet above the ground. The balloon is traveling downward at 16 feet per second init
Marysya12 [62]

Answer:

3 seconds.

Step-by-step explanation:

Since we are figuring out when the water balloon will hit the ground, y will need to be equal to 0.

0 = - 16t² - 16t + 96

Now we simply factor the trinomial to find t.

0 = -16(t² - t - 6)

0 = (t - 3)(t + 2)

t - 3 = 0 ⇒ t = 3

t + 2 = 0 ⇒ t = -2

Since we are referring to time, we need to use the positive value. Therefore, the water balloon will take 3 seconds to hit the ground.

Which is bigger, a third of 45 or one-sixth c<br> 138?
Ksju [112]

Applying the knowledge of fractions, the bigger one is: one-sixth of 138.

<h3>What are Fractions?</h3>

Fractions can be defined as a part of a digit or number, and are not whole numbers. For example, a third is 1/3, one-sixth is 1/6, which are both fractions.

Therefore, let's evaluate each statement:

1/3 of 45 = 1/3 × 45 = 15

1/6 of 138 = 1/6 × 138 = 23

Therefore, the bigger of the two is: one-sixth of 138.
