False. The sum is -4:
-5 + -2 = -7
-7 + 3 = -4
Answer:
CosA/CosB =1
CosA = Adjacent side/Hypotenuse
=AC/AB = 3/4.24
Cos B = Adjacent side/Hypotenuse
= BC/AB = 3/4.24
CosA/CosB = (3/4.24)/(3/4.24) = 1
The value of CosA/CosB = 1
Answer:
$94.38
Step-by-step explanation:
find 20 percent of 78.65
78.65 * .2 = 15.73
(20% as a decimal is .20, or .2)
add the tip to the cost of the meal
78.65 + 15.73 = 94.38
total cost is $94.38
The answer is -.25 4(-.25) = -1 +6 = 5! Hope this helps!!! :)
This problem can be solved using proprtions. Once you set up the proportion, the calculations are easy.
Let x = number of pens made in 1 second.
Now, you just cross multiply and solve.
9 = 3x
x = 3
The rate is 3 pens per second.
