Answer: 296.7

i did surface area but i dont think this is right

Step-by-step explanation:

2πr^2+2πrh

2(3.14)(1.5)^2+2(3.14)(1.5)(30)

2(3.14)(2.25)+2(3.14)(45)

2(7.065)+2(141.3)

14.13+282.6=296.73

rounded to the nearest tenth: 296.7

Answer:

The answer instead is 10:14.

Step-by-step explanation:

In this case, there are ten boys and fourteen girls in this class. The ration would then be 10:14. Instead, Jeff said 5:12 which isn't correct. He can correct it by using the number of boys given, find the difference of girls in a class of twenty-four students, and then get his answer!

Please tell me the function( will mark as brainiest) thanks
Alecsey [184]

Answer:

y = 8x+8

Step-by-step explanation:

We can solve for the function by finding the slope of the linear function using two points. Let's use (0,8) and (1,16)

Slope formula is: m = \frac{y2-y1}{x2-x1}

Plug in the 2 points: m = \frac{16-8}{1-0}

Simplify: m = 8

So now, for the equation y = mx+b, we have m which is y = 8x+b

Now we need to find b by using another point from this linear function.

We can use the point (2,24).

Plug this point into the equation y = 8x+b

  • 24 = 8(2)+b
  • 24 = 16 + b
  • b = 8

We have now found the equation of the linear function: y = 8x+8

Answer:

Option C. \$23,134.61

Step-by-step explanation:

we know that

A=\frac{P[(1+r)^{n} -1]}{r(1+r)^{n}}

we have

P=\$400

r=0.075/12=0.00625

n=6*12=72\ months

substitute in the formula

A=\frac{400[(1+0.00625)^{72} -1]}{0.00625(1+0.00625)^{72}}\\ \\A=\frac{226.446972}{0.009788}\\ \\A=\$23,134.61
