Answer:
h=48
Step-by-step explanation:
You should create an even proportion. So you could do seconds over heartbeats or the other way around. I decided to do the other way around. Since yu want to see h in m minutes and in a minute there are 60 seconds, I did 8/10 = h/60. Instead of cross multiplying, I saw that 10 times 6 is 60 so 8 x 6=h. 8 x 6 = 48 so h=48.

<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
<span>The <u>correct answers</u> are:
1, 3 and 4.
Explanation<span>:
We use synthetic division to divide a polynomial by a binomial of the form x-c, where c is a constant. x-c is a linear term, so 1 is true.
When we begin synthetic division, we place the value of c outside the box. Since c is a constant, and not a variable, then 2 is not true.
When we finish synthetic division, if there is a number other than 0 in the last term of the quotient (answer), this is a remainder. This makes 3 true.
When converting the answer from synthetic division to a polynomial, we use our numbers in the quotient as the coefficients of variables, starting with exponents that are 1 less than the original dividend; this makes 4 true.</span></span>
