Answer:

1)  f(g(-2))=-3,      2) g(f(0))=5

Step-by-step explanation:

1)f(g(-2))

First, g(-2) means that x=-2. Hence, you must find the value of g(x) in the table when x=-2. You can see that, when x=-2, g(-2) = -3.

Next, you must find f(-3) in the graph, where x=-3. You can see in the graph that, when x=-3, f(-3) = -2.

Therefore, f(g(-2))=-3

2) g(f(0))

In the case, we must apply the inverse procedure. First, check in the graph that, when x=0, f(0) =1.

Next, we must look at the table and see that, when x=1, g(1)=5. Hence,

g(f(0))=5

Answer:

cos(300)

Step-by-step explanation:

you must use the identity:

cos(a+b)=cos a cos b - sin a sin b

In this case a=140 and b=540. Hence, the answer is

cos(140+520)

or

cos(660)

However,   it's about a round and a half to the circle,

hence, 660 is the same as 660-360=300.

Finally, the answer is cos(300)

Answer:

Let a be the width and b the length

a+3=b

a*b=54

a(a+3)=54

a^2+3a-54=0

a=6

19/20 hour he take to get to Ford from the time he wakes up.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Ryan takes = 7/10 hour to get ready.

Ryan takes 1/4 hour to travel.

So, the total time he taken

= 7/10 + 1/4

= 7/10 x 2/2 + 1/4 x 5/5

= 14/20 + 5/20

=19/20

Answer:

0.057

Step-by-step explanation:

Given that:

Number of machines, [tex]n[/tex] = 10

Probability, that an individual machine will break down, [tex]p[/tex] = 0.1

Probability, that an individual machine will not break down, [tex]q=1-[/tex][tex]p[/tex]

To find:

The probability that on a given day, three machines will break down = ?

Solution:

First of all, let us have a look at the probability formula:

[tex]P(x=r) = _{n}C_{r}p^rq^{n-r}[/tex]

Here, r = 3

Putting the values:

[tex]P(x=3) = _{10}C_{3}p^3q^{10-3}\\\Rightarrow P(x=3) = _{10}C_{3}{0.1}^30.9^{7}\\\Rightarrow P(x=3) = 120\times{0.1}^30.9^{7}\\\Rightarrow P(x=3) = \bold{0.057}[/tex]

Answer:

It is C

Step-by-step explanation:

c is the only answer that makes sense because 10 is 5 more than 5 as the length so 5 is 5 less than 10.

The dimensions of the quilt are width = 10 and length = 5 which is the correct answer would be option (C).

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

The length of the quilt Sally is making is five inches shorter than the width. The perimeter measures 30 inches which are given in the question.

The perimeter of a rectangle = 2L + 2W

30 = 2L + 2W

L + W = 15

The length is equal to five inches less than the width.

So L = W - 5

Substitute the value of L = W - 5 in the equation L + W = 15

W - 5 + W = 15

2W = 20

W = 10

L = 5

Therefore, the dimensions of the quilt are width = 10 and length = 5.

Answer:

[tex] \frac{ - 1}{4} [/tex]

1. We know that 1 feet = 12 inches

let x be a number of inches, which when added to 18 inches will give 7 feet

18 inches + x inches = 7 feet

18 inches + x  inches = 84 inches                       [1 feet = 12 inches]

x inches = 84 inches - 18 inches

x inches = 66 inches

2. We know that 1 mile = 1760 yards

let x be the number of yards, when added to 2000 yards will be equal to 2 miles

2000 yards + x yards = 2 miles

2000 yards + x yards = 3520 yards

x yards = 1520 yards

3. We know that 1 feet = 12 inches

Number of feet = Given number of inches / 12

Number of feet = 108 / 12

Number of feet = 9 ft.

4. We know that 1 mile = 5280 feet

let x be the number of feet, when added to 8800 feet. will be equal to 8 miles

8800 feet + x feet = 8 miles

8800 feet + x feet = 42240 feet             [1 mile = 5280 feet]

x feet = 42240 - 8800

x feet = 33440 ft.

5. We know that 12 inches = 1 feet

let x be the number of inches, when added to 37 inches, will be equal to 5 feet

37 inches + x inches = 5 feet

37 inches + x inches = 60 inches         [12 inches = 1 feet]

x inches = 23 inches

6. We know that 1 yard = 3 feet

So, (number of yards)*3 = (number of feet)

Number of yards = number of feet / 3

Number of yards = 73 / 3 = 24.33 yards

7. We know that 1 yard = 3 feet

let x be the number of feet added to 15 feet to make 9 yards

15 feet + x feet  = 9 yards

15 feet + x feet = 27 feet       [1 yard = 3 feet]

x feet = 12 ft

8. We know that 1 mile = 1760 yards

let x be the number of yards remaining to reach 4 miles

3000 yards + x yards = 4 miles

3000 yards + x yards = 7040

x yards = 4040 yards

9. We know that 1 yard = 3 feet

So, number of yards * 3  = number of feet

replacing the values:

number of yards*3 = 114

number of yards = 114/3

number of yards = 38 yards

10. We know that 1 mile = 5280 feet

let x be the number of feet that must be added to 9000 feet to make 3 miles

x feet + 9000 feet = 3 miles

x feet + 9000 feet = 15840 feet

x ft = 6840 ft

11. We know that 12 inches = 1 feet

let x be the number of inches that must be added to 46 inches to get a length of 9 feet

46 inches + x inches = 9 feet

46 inches  + x inches = 108 inches

x inches = 108 - 46 inches

x inches = 62 inches

12. We know that 1 mile = 1760 yards

let x be the number of yards that must be added to 3500 yards to make 2 miles

3500 yards + x yards = 2 miles

3500 yards + x yards = 3520 yards

x = 20 yards

13. We know that 1 ft = 12 inches

So, number of feet * 12 = number of inches

number of feet = number of inches / 12

number of feet in 252 inches

Number of feet = 252/12

Number of feet = 21 ft

14. We know that 1 mile = 5280 feet

let x be the number of feet, when added to 6500 feet, will be equal to 2 miles

x ft + 6500 ft = 2 miles

x ft + 6500 ft = 10560 ft

x ft = 4060 ft

15. We know that 1 mile = 5280 feet

let x be the number of feet, when added to 4500 feet, will be equal to 1 mile

x ft + 4500 ft = 1 mile

x ft + 4500 ft = 5280 ft

x ft = 780 ft

Answer:

First no. = 27

Second no. = 29

Third no. = 31

Step-by-step explanation:

First no. = a (smallest no.)

Second no. = a + 2

Third no. = a + 4 ( largest no.)

Given,

3a - 3 + 2(a + 4) = 140

3a - 3 + 2a + 8 = 140

(3a + 2a) + (-3 + 8) = 140

5a + 5 = 140

5a = 140 - 5

5a = 135

a = 135/5

a = 27

First no. = a = 27

Second no. = a + 2 = 29

Third no. = a + 4 = 31

Around 2 miles

Step-by-step explanation:

Given that the speed of light in this problem travels at 1088 feet per second, with a mile being 5280 feet. If Snoopy heard the sound of thunder 10 seconds later, then snoopy is 10880 feet away or 10880/5280 = 2.0606... ≈ 2 miles.

This is done using the formula for speed which is. s = d/t ; speed = distance divided by time.

To find the distance, rearrange the formula by multiplying time on each side so that we are solving for distance.

s = d/t

×t ×t

(cancels the denominator of t in d/t)

s × t = d / t × t

st = d

(symmetric property of equality)

d = st ; distance = speed × time.

now that we have this formula, just multiply the speed of light, and the time it took for Snoopy to hear the thunder.

Distance = 1088ft/s × 10s = 1088ft × 10 (seconds cancel) = 10880ft.

The final step to finding the milage is converting this measurement of feet into miles by dividing by 5280 as stated in the problem.

So 10880ft/5280ft = 2 R(remainder) 320 ft = 2 + 320 / 5280 = 2 + 6/99 = 2 + 0.0606... = 2.0606... ≈ 2

So basically, let's look at the given. In the problem, Leon is charged a fee of 75. The interest rate would be 12.5 % if he doesn't pay his due amount. So in order to get the total amount that he has to pay if he doesn't pay on time, you just need to multiply 75 with 12.5% or simply 0.125. If you do this, you will get 9.375. After that, you add 9.375 to the principal amount which is 75 and you will get 84.375. So Leon has to now pay a total of 84.375.
