Adele spent 8 minutes on the phone while routing 2 phone calls. If she routes 4 phone calls, how much time will Adele have spent on the phone in total? Solve using unit rates.

Answers

Answer 1

Answer:

16 minutes

Step-by-step explanation:

Given

Represent minutes with M and Phone calls with P.

When M = 8; P = 2

Required

Determine M when P = 4

First, we need to determine the constant of proportion using:

[tex]M = k * P[/tex]

Where k represents the constant:

[tex]8 = k * 2[/tex]

Divide through by 2

[tex]4 = k[/tex]

[tex]k = 4[/tex]

Solving for M, when P = 4

Substitute 4 for P and 4 for k in [tex]M = k * P[/tex]

[tex]M = 4 * 4[/tex]

[tex]M = 16[/tex]

Hence:

She spent 16 minutes in total

Ten students in your class put their names on slips of paper inside a box. Out of the ten students, four are girls, and six are boys. Five names are chosen.
What is the probability that three girls and two boys are chosen?

1.90%
350%
7.14%
23.81%

Answers

Answer:

23.81%

Step-by-step explanation:

The total number of ways to select 5 out of 10 will be;

10 C 5 = 252

The number of ways of selecting 2 boys out of 6 will be

6 C 2 = 15 ways

The number of ways of selecting 3 girls out of 4 will be

4 C 3 = 4 ways

The probability of both will be;

(4 * 15)/252 = 60/252 = 0.238095238095

To the nearest percentage, that will be 23.81%

6 blue slabs have a mean weight of 7 kg. 3 yellow slabs have a mean weight of 5 kg. 1 grey slab has a mean weight of 9kg. work out the mean of 10 slabs

Answers

Answer: 6.6kg

Step-by-step explanation:

6 blue slabs have a mean weight of 7 kg. The total weight of the 6 blue slabs will be:

= 6 × 7kg

= 42 kg

3 yellow slabs have a mean weight of 5 kg. The total weight of the 3 yellow slabs will be:

= 3 × 5kg

= 15kg

1 grey slab has a mean weight of 9kg.

To get the mean of the 10 slabs, we add their total weights together and divide by 10. This will be:

= (42kg + 15kg + 9kg)/10

= 66kg/10

= 6.6kg

Based on the information given the mean of 10 slabs is 6.6 kg.

Formulate

(9+5×3+6×7)/10

Calculate the quotient

9+15+6×7/10

9+15+42/10

Calculate the sum or difference

24+42/10

66/10

Reduce the fraction

33/5

Hence:

Mean=6.6 kg

Inconclusion  the mean of 10 slabs is 6.6 kg.

(a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150
application fee.
(b) y =3/4x
(c) y=1/2x - 6

Answers

Answer:

a. Non proportional

b. Proportional

c. Non proportional

Step-by-step explanation:

Here, we want to determine if each situation is proportional or not

a) Non-proportional

This is because the amount y paid in a month will be;

y = 1400x + 150

Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship

b) proportional

y = 3/4x

The value of y is dependent solely on that of x, so the relationship is proportional

c) non proportional

Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional

Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.

Answers

Answer:

$434.16346

Step-by-step explanation:

Given that :

Gross earning= $14500

Federal, state and local taxes = 11%

0.11 * $14500 = $1595

FICA tax rate = 7.65%

0.0765 * 14500 = $1109.25

Personal deduction :

3.5% * 14500

0.035 * 14500 = $507.50

Total deduction :

$(1595 + 1109.25 + 507.50)

= $3211.75

Net earning : $(14500 - 3211.75) = 11288.25

Since she is paid bi weekly:

Number of biweeks in a year = 52 /2 = 26

Number of payments per annum = 26

Hence,

Net pay per period :

11288.25 / 26

= $434.16346
