PLS SOMEONE HELP ME ASAP

Mathematics
1 answer:
babymother [125]3 years ago
8 0

Answer:

A. (2i)(8) = d. 16i

B. 16i³ = b. -16i

C. (2i)⁴ = a. 16

D. (2i)(8i) = c. -16

Step-by-step explanation:

A. Multiply 2i by 8 to get 16i, which corresponds to d.

B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.

C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.

D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.

Anthony earned $131 in tips last night while working at the restaurant. If his tips consisted of $1 bills and $5 bills only and
Nadya [2.5K]

Answer:

21

Step-by-step explanation:

Let x = $1 bill

Let y = $5bill

<em>Translating the word problem into an algebraic equation;</em>

<em>For the total number of bills;</em>

x + y = 47 .........equation 1

<em>For the total number of tips;</em>

x + 5y = 131 ..........equation 2

<em>*Solving the linear equation by using the substitution method*</em>

<em>Making x the subject in equation 1:</em>

x = 47 - y .......equation 3

<em>Substituting "x" into equation 2;</em>

(47 - y) + 5y = 131

<em>Simplifying the equation, we have;</em>

47 + 4y = 131

4y = 131 - 47

4y = 84

y = \frac {84}{4}

y = 21 (For the $5 bills).

<em>Therefore, Anthony received 21 pieces of the $5 bills.</em>

To find x;

Substituting "y" into equation 3;

x = 47 - 21

x = 26 (For the $1 bill).

Write money amounts using a leading zero if necessary &amp; with 2 decimal places (For example: 0.80 or 0.72 or 1.23)
goldenfox [79]

9514 1404 393

Answer:

  1. 63 mph
  2. 3 donut holes per kid
  3. $0.70 per pound
  4. $2.25 per km

Step-by-step explanation:

In this context, "per" and "for" mean "divided by."

  1. 630 mi/(10 h) = 63 mi/h
  2. (24 dh)/(8 kid) = 3 dh/kid
  3. $3.50/(5 lb) = $0.70 /lb
  4. $32/(14 2/9 km) = $32/(128/9 km) = $(9/4)/km = $2.25 /km
