Answer:
Most credit card companies also apply a late payment penalty if you owe a balance and do not make a payment. Ignoring that fee, Miriam's balance will increase as:
B(n) = 750(1.018)^n
where B(n) is Miriam's balance after n months. The progression will be:
$750.00
$763.50
$777.24
$791.23
$805.48
Step-by-step explanation:
Percent Change from 125cm to 87.5cm
% Change = (87.5 - 125) / 125 * 100%
= -37.5 / 125 * 100%
= -0.3 * 100%
= -30 %
The percent change is -30 % or 30% decrease.
Answer:
<em><u>x=-2</u></em>
Step-by-step explanation:
<u>Let's solve your equation step-by-step.
</u>
<em>3x+9=x+5
</em>
<u>Step 1: Subtract x from both sides.
</u>
<em>3x+9−x=x+5−x
</em>
<em>2x+9=5
</em>
<u>Step 2: Subtract 9 from both sides.
</u>
<em>2x+9−9=5−9
</em>
<em>2x=−4
</em>
<u>Step 3: Divide both sides by 2.
</u>
<em>2x
/2=-4/2</em>
<em>x=−2
</em>
Answer:
Ok where's the fractions?
Step-by-step explanation:
For #4, for any right triangle a^2 + b^2 should equal c^2. Square roots are just numbers to a power of 1/2. You can multiply the exponents together of #^(2 * 1/2) and simply get #. With that in mind, we can use sqrt2 as our a, sqrt3 as b, and sqrt5 as c, since c is always the largest number. For A, sqrt2 squared is 2, for B, sqrt3 squared is 3, and c is 5. Since 2+3 does indeed equal 5 you have a right triangle.
For #5, dilating by 3 means our length will be three times as long as whatever it is there. To find out how long the line is, we can make a right triangle. The differences between the x values are 6, and the differences between the y values are 12. A^2 + b^2 = c^2, 144 + 36 = 180, c= sqrt180, which is approx. 13.416. Multiply that by 3 and you get ≈40.25 as K’L’.
