Answer:
200
Step-by-step explanation:
Given:
0.482 x 61.2^2 ÷ √98.01
61.2^2 = 3745.44
√98.01 = 9.9
So,
0.482 × 3745.44 ÷ 9.9
= 1,805.30208 ÷ 9.9
= 182.35374545454
To one significant figure
= 200
One significant figure means only 1 non zero value and others are zero
Multiply each side by 9:
18 + 4x > 36 + 9x
Subtract 18 from each side:
4x > 18 + 9x
Subtract 9x from each side:
-5x > 18
Divide each side by -5:
x < -3.6
Hope this helps!
Hello,
The function is y=4x+8.
We exchange x and y ==>x=4y+8
and we seach y:
4y=x-8 ==>y=(x-8)/4 ==> y=x/4-2
Answer A
Answer: 9%
Step-by-step explanation:
<em><u>Question:</u></em>
Crispy clover, a popular vegetarian restaurant, introduced a new menu that had 20% more dishes than the previous menu. The previous menu had D dishes. Which of the following expressions could represent how many dishes crispy clovers new menu has?
<em><u>Answer:</u></em>
<em><u>The expression could represent how many dishes crispy clovers new menu has is:</u></em>

<em><u>Solution:</u></em>
Given that,
The new menu had 20% more dishes than the previous menu
The previous menu had D dishes
Therefore,
Previous menu = D dishes
New menu = 20 % more dishes than previous menu
Which means,
New menu = 20 % of previous menu + previous menu
Therefore,
New menu = 20 % of D + D
Solve the above equation

Therefore, new menu has 1.2D dishes
