Answer:
27 cookies in each bag.
Step-by-step explanation:
3 trays of 36 cookies is 3 x 36 = 108
108 cookies into 4 bags
108/4 = 27
27 cookies in each bag.
Answer:
Step-by-step explanation:
Ah...right triangle trig. Gotta love this stuff (you better, because it never goes away!). We need to remember SohCahToa which tells us that the sin of an angle is equal to the side opposite the angle over the hypotenuse; the cos of an angle is equal to the side adjacent to the angle over the hypotenuse; the tan of an angle is equal to the side opposite the angle over the side adjacent the angle. x is the side across from our given angle, while 7 is the side adjacent. That means that we will use the tangent ratio to solve.
and filling in:
. Solving for x:
7tan(48) = x. Do this on your calculator in DEGREE mode (NOT radians!) to get that x = 7.77 which rounds nicely to D: 7.8
5 lbs equals 80 ounces because 1 lb is 16 oz
Answer:
The inequality solves to r > 5
The graph has an open hole at 5, with shading to the right
===========================================================
Explanation:
6+9r is the same as 9r+6
We'll subtract 6 from both sides to undo the +6
9r+6 > 51
9r+6-6 > 51-6
9r > 45
Then we'll divide both sides by 9 to isolate r.
9r/9 > 45/9
r > 5
The entire time, the inequality sign stays the same.
The solution set involves anything larger than 5. So something like r = 7 would work while r = 2 does not.
Visually, we'll have an open hole at 5 on the number line. Shade to the right to indicate things larger than 5. The open hole tells the reader "do not include 5 as part of the solution set".
