Solving (b): Solve for distance
We have:
Cross multiply
The answer is 43.72 <span>× 10¹² kg.</span>
It is given:
the mass of the Rock of Gibraltar:
m₁ = 1.78 × 10¹² kg
the mass of the Antarctic iceberg:<span>
m</span>₂ = 4.55 × 10¹³ kg = 4.55 × 10 × 10¹² kg = 45.5 × 10¹² kg<span>
To calculate how many more kilograms </span><span>is the mass of the Antarctic iceberg than the mass of the Rock of Gibraltar we need to subtract them:
</span>m₂ - m₁ = 45.5 × 10¹² kg - <span>1.78 × 10¹² kg
</span>m₂ - m₁ = (45.5 - 1.78) <span>× 10¹² kg
</span>m₂ - m₁ = 43.72 × 10¹² kg
First, put the equation of the line given<span> into slope-intercept form by solving for y. You get y = 2x +</span>5<span>, so the slope is –2. </span>Perpendicular lines<span> have opposite-reciprocal slopes, so the slope of the </span>line<span> we want to find is 1/2. Plugging in the </span>point given<span>into the </span>equation<span> y = 1/2x + b and solving for b, we get b = 6.</span>
Answer: the option A. 23.1%
Explanation:
1) You are given the formula:
<span>Mark up rate on selling price = markup rate cost / (1+ markup rate on cost)
</span>
2) You are given the markup rate cost: 30% = 0.30
3) Then, you just have to replace the value in the formula:
<span>Mark up rate on selling price = 0.30 /(1+ 0.30) = 0.30 / 1.30 ≈ 0.2308
</span><span>
</span><span>
</span><span>To pass to percent just multiply by 100: 0.2308 × 100 = 23.08% ≈ 23.1%
</span><span>
</span><span>
</span><span>And that is the answer.
