Anestetic [448]

Inequality: 21d+25≤115

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Step-by-step explanation:

Given,

Per day rent = $21.00

Per mile rent = $0.10

Miles to be driven by Jim = 250

Cost of 250 miles = 250*0.10 = $25

Amount Jim can spend = $115.00

Let,

d represent the number of days.

Per day rent*number of days + cost of 250 miles ≤ Total amount to spend

21d+25≤115

Subtracting 25 from both sides

21d+25-25\leq 115-25\\21d\leq 90

Dividing both sides by 21

\frac{21d}{21}\leq \frac{90}{21}\\d\leq 4.28

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.
alexandr1967 [171]

The total cost of the bracelet will be $96.

The number of charms will be 2.

Step-by-step explanation:

Given,

Cost per charm at Dayton Fine Jewelry = $17

Cost of bracelet = $62

Let,

x be the number of charms

y be the total cost

y = 17x+62   Eqn 1

Cost per charm at Cain Jewelers = $18

Cost of bracelet = $60

y = 18x+60   Eqn 2

For same cost;

Eqn 1 = Eqn 2

17x+62=18x+60\\62-60=18x-17x\\2=x\\x=2

Putting x=2 in Eqn 1

y=17(2)+62\\y=34+62\\y=96

Putting x=2 in Eqn 2

y=18(2) +60\\y=36+60\\y=96

The total cost of the bracelet will be $96.

The number of charms will be 2.

What is the probability that either two heads or three heads will be thrown if six fair coins are tossed at once?
lesantik [10]

Answer:The right answer will be

0. 546875

Step-by-step explanation:

When 6 coins are tossed , the total number of outcomes is 2*2*2*2*2*2= 64

The number of ways of getting two heads are 6!/2!*4!=15.

The probability of getting two heads P(A) is 15/64 .

In the same way, the probability of getting three heads P( B) is 5/16.

Now, P(A)+P(B)= 0.546875

Answer:

Cam

Step-by-step explanation:
