Judy spent 1 hr 15 min less than Sandy exercising last week. Sandy spent 50 minutes less than Mary, who spent 3 hours at the gym

kondaur [170]

Answer:

Judy spent 55 minutes exercising

Step-by-step explanation:

Here, we want to know the amount of time Judy spent exercising.

We proceed as follows;

Mary spent 3 hours , sandy spent 50 minutes less than Mary. The amount of time spent by Sandy is thus 2hrs 10 minutes

Judy spent 1hr 15 min less, the amount of time he spent is thus

2hrs 10 minutes - 1 hr 15 min

2 hrs 10 minutes is same as 2(60) + 10 = 120 + 10 = 130 minutes

I hr 15 minutes = 60 + 15 = 75 minutes

The amount of time spent is thus 130 - 75 = 55 minutes

Does the budgeted amount cover the actual amount for expenses, savings, and emergencies? a) no, it's short $207.00. b) no, it's

Korvikt [17]

The expense amount is more than the savings amount. No, it's short $207 then the correct option is A.

<h3>What are statistics?</h3>

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.

From the table, we have

The amount of the savings will be

Saving amount = $ 20

Then the amount of the expense will be

Expense amount = 150 + 75 + 2 = 227

Then the budgeted amount covers the actual amount for expenses, savings, and emergencies will be

→ savings amount - expense amount

→ 20 - 227

→ $ 207

Thus, the expense amount is more than the savings amount. No, it's short $207.

When the nth root of a is written, it is the positive value that is shown

allsm [11]

The nth root of a is always positive unless, a < 0 and "n" is an odd number. Also if a < 0 <span> and "n" is an even number, then it's an imaginary number. I hope this helps a lot</span>

What is the present value of 6000 received 14 years from today when the interest rate is 10%

likoan [24]

Answer:

$14400

Step-by-step explanation:

Given data

Principal= 6000

Time= 14 years

Rate= 10%

Let us use the simple interest expression to find the final amount

A=P(1+rt)

substitute

A=6000(1+0.1*14)

A=6000(1+1.4)

A=6000*2.4

A=$14400

Hence based on a simple interest model the final amount is $14400
