Charlie wants to make a one-time investment in an account that earns 4% interest compounded quarterly. To earn $315,930 after 21
KIM [24]

Answer:

B.  $136,960.54

Step-by-step explanation:

Rate = r = 4%

Times = b = 4

Future Value = A = $315,930

No. pf Years = n = 21

Present Value = P = ?

A = P [1 + (r / b)]ⁿᵇ

$315,930 = P [1 + (0.04 / 4]²¹ ˣ ⁴

$315,930 = P [1 + 0.01]⁸⁴

$315,930 = P [1.01]⁸⁴

$315,930 = P x 2.306723

P = $315,930 / 2.306723

P = $136,960.54

A trapezoid has a height of 8 cm and bases with lengths of 14 cm and 8 cm. Tina says the area of the trapezoid is 176 cm2.
Sonbull [250]

Answer:

Step-by-step explanation:

Let's do this properly:

                                 

Area of trapezoid =  average length times height.

Here,

Area = (1/2)(8 cm + 14 cm)(8 cm), or

         = (11 cm)(8 cm) = 88 cm^2

It appears that Tina forgot to divide the sum of 14 cm and 8 cm by 2.  Thus, her answer is twice as large as it should be.

Water freezes at 0° Celsius. The table shows five different temperatures in degrees Celsius. Indicate whether each temperature i
KATRIN_1 [288]
0.5 is above because that .5 of a change is keeping the water from freezing because it is still slightly babouche freezing point.

-13 is below because the number is a negative so is below 0 anyway and is below the freezing point.

100 is above because the number 100 is higher than 0 so it’s above freezing point.

5.5 is above because it is a larger number than the freezing point so the water would not freeze yet at this temperature.

-2.25 is below because it’s a negative number.

I think that’s what you meant not 100% sure but that’s how I would do it :)

AB = \sqrt{36 + 9}

AB = \sqrt{45}

AB = 6.708(approx)

To give answer in 3 significant figures :
