Answer:

[tex]11x\leq 90[/tex]

Step-by-step explanation:

11 is the amount per hour, x stands for the number of hours, and he needs to earn at least 90 dollars.

Answer: 54:4

Step-by-step explanation:

b = number of beetles

r = number of birds

s = number of spiders

"She has an equal number of beetles, birds and spiders". That means b = r = s. They all stand in for the same number, and that number being some positive whole number.

One spider has 8 legs, so s of them have 8s legs. One beetle has 6 legs, so b of them have 6b legs. One bird has 2 legs, so r birds have 2r legs.

In total, all of the animals have 6b+2r+8s legs. We'll replace r and s with b, since earlier we were given that b = r = s.

So we end up with:

6b+2r+8s

6b+2b+8b

(6+2+8)b

16b

The number of legs of all the animals is equal to 16 times the number of beetles. Set this equal to 270 and isolate b

16b = 270

b = 270/16

b = 16.875

We run into a problem. It's not possible to have the variable b equal to a non-whole decimal number like this. It's possible your teacher made a typo somewhere. I would ask them for clarification.

Answer:

0.1333 = 13.33% probability that bridge B was used.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Arrives home by 6 pm

Event B: Bridge B used.

Probability of arriving home by 6 pm:

75% of 1/3(Bridge A)

60% of 1/6(Bridge B)

80% of 1/2(Bridge C)

So

[tex]P(A) = 0.75*\frac{1}{3} + 0.6*\frac{1}{6} + 0.8*\frac{1}{2} = 0.75[/tex]

Probability of arriving home by 6 pm using Bridge B:

60% of 1/6. So

[tex]P(A \cap B) = 0.6*\frac{1}{6} = 0.1[/tex]

Find the probability that bridge B was used.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1}{0.75} = 0.1333[/tex]

0.1333 = 13.33% probability that bridge B was used.

Answer:

b - 4

Step-by-step explanation:

This can be done by factoring.

Area = length x width

2b^2 - 5b - 12 = (2b + 3)( ???)

Factor the area into (2b + 3)(b - 4).  The width is b - 4.

Answer:

The answer is b - 4

Step-by-step explanation:

Step-by-step explanation:

B.

AC =BC

2x-6=x+8

2x-x=8+6

x=14

5) AC = 2x-6=2(14)-6=28-6= 22

6) BC = x+8= 14+8= 22

7) AB = AC+BC = 22+22= 44

C.

AC =BC

4x+10=7x-5

4x-7x= -5-10

-3x= -15

x= -15/-3 = 5

8) AC = 4x+10=4(5) +10=20+10= 30

9) BC = 7x-5= 7(5) -5=35-5= 30

10) AB = AC+BC = 30+30= 60

B) Solution

AC = BC

→ 2x-6 = x+8

→ 2x-x = 8+6

→ x = 14

5:- AC = 2x-6 = 2(14)-6 = 28-6 = 22

6:- BC = x+8 = 14+8 = 22

7:- AB = AC+BC = 22+22 = 44

C) Solution

AC = BC

→ 4x+10 = 7x-5

→ 4x-7x = -5-10

→ -3x = -15

→ x = -15/-3

→ x = 5

8:- AC = 4x+10 = 4(5) +10 = 20+10 = 30

9:- BC = 7x-5 = 7(5)-5 = 35-5 = 30

10:- AB = AC+BC = 30+30 = 60

Answer:

The amount of tax is $14.37 and the tax rate percentage is 12.18%

Step-by-step explanation:

Find the amount of tax by finding the difference between the cost and selling price:

132.37 - 118

= 14.37

Find the tax rate percentage by dividing the tax by the original cost, and multiplying it by 100:

(14.37/118) x 100

= 12.18

The amount of tax is $14.37 and the tax rate percentage is 12.18%

Answer:

New volume will become 187.5 inch²

Step-by-step explanation:

Initial volume,

V = lbh

Put all the values,

V = 6.25 × 2.5 × 6

V = 93.75 inch³

When the length is doubled, l' = 2(6) = 12 inch

New volume,

V' = 12 × 6.25 × 2.5

= 187.5 inch²

So, when the length is doubled, the new volume will become 187.5 inch².
