Answer:
28.3 yards per hour
Step-by-step explanation:
36 inches=1 yard
17inches*1 yard =.47 yards
/36 inches
In one minute, the turtle moves .47 yards.
60 minutes=1 hour
60minutes * .47 yards =28.3 yards per hour
Answer:
this is an example
Step-by-step explanation:
There are a few different ways to approach this problem, including the following two methods.
1) Find 20% of the original price, then subtract that amount from the original price.
To find a percentage of a number, you multiply the number by the percentage. (You are finding a part of a whole.)
20% = 20/100 = 1/5 or 20% = 0.20
Original Price: $24 Find 20% of $24. (Note: "of" is taking part of a whole, so you multiply.)
0.20 x 24 = 4.80 This is the mark down, or the amount you subtract from original price.
Sale Price = Original Price - Mark Down
= 24.00 - 4.80
= 19.20
2) If you save 20%, you are still paying 80%. (100-20 = 80) Therefore the sale price is 80% of the original price.
80% = 80/100 = 4/5 or 80% = 0.80
Sale Price = 80% of Original Price
= 0.80 x 24
= 19.20
It would be at 0,7. Plug in 0 for x, and you will get 7 for y.
Answer:
<QRP = 48.2°
Step-by-step explanation:
Given:
PR = 18 cm
QR = 12 cm
Required:
<QRP = angle R
Solution:
Reference angle = <R (<QRP)
Adjacent side length = 12 cm
Hypotenuse = 18 cm
Thus:
Cos (R) = 12/18
cos (R) = 0.6667
<QRP = 48.2° (nearest tenth)
The answer is B.
A linear function is a first-order polynomial, which is of the form y = ax + b. It is called first-order because the power of x is 1.
A second-order polynomial is of the form y = ax^2 + b; which eliminates A. This is also known as a quadratic function.
C. can be simplified to y = 2/3 - 7/x, which probably has a name as well.
D. can be simplified to y - y = 3x/8 + 1/8, which is 0 = 3x + 1 or x = -1/3. Not a linear function
