C+32, in degrees Fahrenheit. The hottest temperature ever recorded in Puerto Rico was 40 degrees Celsius.
Based on the information given, the temperature when converted to Fahrenheit will be 104° Fahrenheit.
Solving the temperature.It should be noted that when converting to Fahrenheit from Celcius, one has to multiply by 1.8 and then add to 32.
In this case, the temperature given in Celcius is 40°. Therefore, the Fahrenheit will be;
= (1.8 × 40) + 32.
= 72 + 32

Answer:
Total number of people surveyed = 118
Number of people who own dogs = 78
Number of people who own cat = 44
Number of people who own both cats and dogs = 26
Number of people who only own dogs = 78 - 26 = 52
Number of people who own only cats = 44 - 26 = 18
Only dog owners + Only cat owners + Both + Neither = Total people surveyed
52 + 18 + 26 + Neither = 118

Answer:
B. (0, 4)
Step-by-step explanation:
A function is "increasing" where its slope is positive (up to the right). Here, the graph has positive slope between x=0 and x=4.
The slope is 0 from x=4 to x=7, and the function is decreasing (has negative slope) for x=7 to x=10.
The interval where f(x) is increasing is (0, 4).

Step-by-step explanation:
given f(x) = 3x^4
so let f(x) be y and to find inverse notation, we have to make x the subject
y = 3x^4
[tex]\frac{y}{3}[/tex] = x^4
x = [tex]\sqrt[4]{\frac{y}{3} }[/tex]

1. how many students like peaches
2. how many students do not like peaches
Answer:
1.) 21
2.) 39
Step-by-step explanation:
1.)
convert 35% into a decimal >> (.35)multiply by the whole number of students. (60) * (.35) = 21By doing this, you're essentially solving for 35 percent of the 60 students.2.)
use the answer from the precious question to solve for the students that don't like peaches.60 - 21 = 39How is this number read? 14.102
Answer:
fourteen and one-hundred-two
Step-by-step explanation:
we tend to read "." as "point" but the proper reading would be to read the number left to the decimal point (14), add the word "and" and then read the number to the right of the decimal point (102)
