Answer: b) 5

Explanation:

The equation for the temperature in Fahrenheit is:

t = 5h + 61.4

Where h is the number of hours after 4:00 pm

then if this is compared with a linear equation, the y-intercept is 61.4 Fahrenheit, and the slope is 5 Fahrenheit/hour

Now we want to know by how many degrees Fahrenheit will the temperature rise each hour until 4:00 PM, we need to look at the slope in order to answer this.

We know that the slope is 5 Fahrenheit/hour, so each hour that passes the temperature increases by 5 degrees Fahrenheit.

The right option is b) 5.

1) What percent of 440 is 369?

Answer:

119.24

Explanation:

Step 1: We make the assumption that 369 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100%=36.

Step 4: In the same vein, x% = 440.

Step 5: This gives us a pair of simple equations:100%=369(1) 440(2) = x%

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS(left hand side) of both equations have the same unit (%); we have 100%/x% = 369/440

Step 7: Taking the inverse (or reciprocal) of both sides yields x%/100% = 440/369

Therefore, 440 is 119.24% of 369.
