The area of scale drawing of the classroom using the scale factor of 3 cm per foot that has 18 feet length and has 20 feet width is 40 squared cm. This is computed by dividing first the sides by 3 and multiply the result to each other.
B. 0
because it’s a positive parabola and the y-intercept is greater than 0
Answer:
The simplified ratio is<em> 7:6</em>
Step-by-step explanation:
First we have to find the <em>GCF</em> of <em>both 154 and 132</em>. Since the <em>GCF is 22</em>, we will <em>divide 154 by 22</em> and we get<em> 7</em>. Now <em>divide 132 by 22 </em>and we get <em>6.</em> Therefore, the simplest form or the ratio 154:132 is <em>7:6.</em>
Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
...(ii)
Substitute the value of x from (ii) in (i).
Divide both sides by 4.
Putting
in (i), we get



Therefore, Mingfa have $95.
