Hello! So the blocks are lined up in rows of 8. When you count the number of rows, there are 10 of them. 3 rows of 8 blocks are shaded out of 10 of them. That's 24 blocks shaded out of 80, because 8 * 10 is 80, and 3 * 8 is 24. Let's divide. 24/80 is 0.3.Let's multiply that by 100 to get it in percent form. 0.3 * 100 is 30. There. 30% of blocks are shaded in the picture.
<span>Solve this by substitution:
</span>Solve 5x - 4y = -13 for x:<span><span><span><span>5x </span>− <span>4y </span></span>+ <span>4y </span></span>= -<span>13 + <span>4y </span></span></span>(Add 4y to both sides)
<span><span><u>5x </u></span>= <span><span><u>4y - </u><u>13 </u></span><u> </u> </span></span>(Divide both sides by 5)
5 5
<span>x = <span><span><span><u>4</u></span> y </span>+ -<span><u>13</u><span>
</span></span></span></span> 5 5

5x - 4y = -13, 8x +10y = 12 (enter both equations with a comma between them and it will solve for you and show you step by step.
<span>If the radius of a circle is doubled in length, the circumference of the circle is <span>B. doubled.
</span>C = 2</span><span>πr - this is the equation for circle. So if you double the radius, its circumference also doubles.</span>

Answer: 96 teaspoons
Step-by-step explanation:
If 1 cup contains 16 tablespoons the 2 cups will contain;
= 16 * 2
= 32 tablespoons
If 1 tablespoon contains 3 teaspoons then 32 tablespoons will contain;
= 32 * 3
= 96 teaspoons
Answer:
Step-by-step explanation:
A = Pe^rt
A = total
P = amount you start with
r = rate
t = time
Let's calculate the rate.
99000000 = 94000000e^r*6
Divide each side by 94m
99000000/94000000 = e^6r
Take the natural log of e of both sides.
ln(99000000/94000000) = 6r
Divide each side by 6.
(ln(99000000/94000000))/6 = r
Now we can find the population in 2005.
A = 94000000e^0.00863751131 * 12
A = 104265957
The population in 2005 is 104,265,957 people.
