Answer:

9x10^16

Step-by-step explanation:

Since your exponent 16 is same all you have to do is, Add 2+7 and write the same 10^16

So your answer will be 9x10^16

Hope this helps!

Answer:

9 × 10^{32}

All you have to do is simplify!

Step-by-step explanation:

(2 × 10^{16}) + (7 × 10^{16}) = 9 × 10^{32}

All you have to do to simplify is add the 2 whole numbers together (2+7 = 9) and add the powers together (16 + 16 = 32, so the exponent would be 10^{32}).

I hope this helps!

1. Sarah’s corvette used 30 gallons of
Ivenika [448]

Answer:

60% is the answer 60/100

Step-by-step explanation:

30:50 is the ratio

60% is the percentage

as 60/100 is = 30:50

if it was 30% then the gallons held by her car would be 100

because it was 50 we just multiply the top to make a percentage equal to 30 x 2 = 60.

As 50 x 2 =100

= 60/100

point O lies in the interior of angle MNP. if the measure of MNO is x^2 + 10x, the measure of ONP is x^2 - 2x , and the measure
Triss [41]

Answer:

x = 6; ∠ONP = 24°

Step-by-step explanation:

1. Find the value of x

\begin{array}{rcl}\angle MNP & = & \angle MNO + \angle ONP\\3x^{2} + 12 & = & x^{2} + 10x + x^{2} - 2x\\3x^{2} + 12 & = & 2x^{2} + 8x\\x^{2} + 12 & = & 8x\\x^{2} -8x + 12 & = & 0\\(x - 2)(x - 6) & = & 0\\\end{array}

x = 2 \text{ or }x = 6

2. Find the measures of the angles

(a) x = 2

∠ ONP = x² - 2x = 2² - 2(2) = 4 - 4 = 0

This answer does not make sense because O lies in the interior of ∠MNP.

We disregard x = 2.

(b) x = 6

∠ ONP = x² - 2x = 6² - 2(6) = 36 - 12 = 24
