<h3>Answer:</h3>

3:8:1

<h3>step-by-step explanation:</h3>

3/12 x 144= 36

8/12 x 144= 96

96+36= 132

144-132= 12

12/12=1

Therefore, the ratio of Alyssa's nickels to dimes to quarters is 3:8:1

44 square feet



Diameter (4) divided by 2 is radius (2).


SA = 2πr^2 + 2πrh

SA = 2 * 3.14 * 2^2 + 2 * 3.14 * 2 * 3

SA = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 3

SA = 6.28 * 4 + 6.28 * 3

SA = 25.12 + 18.84

SA = 43.96

Round to the nearest tenth.

SA = 44 square feet

SVEN [57.7K]

Answer:$90


Step-by-step explanation: $30 is the cost. 200 is the percent of Mark-up, so you take 100 percent of 30 and add it together then you get 60. Repeat that step for a total of 90. 100 percent of 30 is 30. So 30+ 30+ 30 = 90.

frozen [14]

Answer:

(2,-2)

Step-by-step explanation:

y=-4x+6

y=3x-8

plug the y's in for each other to get:

-4x+6=3x-8   <----- solve from there

+8            +8

-4x+14=3x

+4x         +4x

14=7x

/7     /7

x=2

now plug the x in to get y (in any problem)

y=3(2)-8

y=6-8

y=-2

Given function of f(x) = 2x - 1 and fg(x) = 10x + 3, find the function of g(x)​
denis-greek [22]

Answer:

The function of g(x) = 5x + 2

Step-by-step explanation:

Let us use the composite function to solve the question

∵ f(x) = 2x - 1

∵ f(g(x)) = 10x + 3

→ f(g(x)) means substitute x in f(x) by g(x)

∴ f(g(x)) = 2[g(x)] - 1

→ Equate the two right sides of f(g(x))

∴ 2[g(x)] - 1 = 10x + 3

→ Add 1 to both sides

∴ 2[g(x)] - 1 + 1 = 10x + 3 + 1

∴ 2[g(x)] = 10x + 4

→ Divide each term into both sides by 2

∵ \frac{2[g(x)]}{2} = \frac{10x}{2} + \frac{4}{2}

∴ g(x) = 5x + 2

∴ The function of g(x) = 5x + 2
