I am pretty sure it is 100 becayse it looks luke it is doubling the number.
Your answer will be in miles per hour
There are two ways to do this. Both use the forumula
d = v * t
Givens
=====
d = 5/9 mile
t = 1/4 hour
Method One
=========
Use your calculator to get rid of the fractions. (Likely both your teacher and your parents will hate this method, But humor me, do it).
d = 5/9 mile = 0.55555 mile
t = 1/4 hour = 0.25 hour
Calculation
========
v = d/t
v = 0.555555 / 0.25
v = 2.2222222 miles per hour.
Method Two
=========
Use the fractions.
d = 5/9 // 1/4 Invert and multiply by the denominator.
d = 5/9 * 4/1
d = 20 / 9
d = 2 2/9
Answer:
84
Step-by-step explanation:
Total students he surveyed: 27
Amount that found it something OTHER than easy: 14 (11 moderate + 3 difficult)
This means that found it something other than easy
Multiply that by 162 to find the proportion for the larger population:
162 * (14/27), and we get 84.
For question 4,
Question 5. Option a and question 6. Option j
Step-by-step explanation:
Step 1:
The three basic formula needed to solve these questions are:
Step 2:
Using the above formula, we solve the following values
Step 3:
For question 5, The triangle's angle = 23°, opposite side = BC inches and hypotenuse = 4 inches.
SO BC is 1.5628 inches, rounding this off to the nearest tenth, we get BC = 1.6 inches which is option a.
Step 4:
For question 6, The triangle's angle = 50°, opposite side = QR m the adjacent side = 8.1 m.
SO QR is 9.65277 meters, rounding this off to the nearest tenth, we get QR = 9.7 inches which is option j.
Answer: The answer is 12 miles per minute
