Answer:
You use the product of powers law of exponents to combine the exponents; this law says to add the exponents.
Step-by-step explanation:
got it right
No because a person can buy as many sandwiches as possible and only pay a $10 delivery fee.
=(4.5)x + 10
Because the angle is a straight angle, it means that the total of DEC and CEF would be 180º. (CEF + DEF = 180º) With this information we can make the equasion:
(11x - 12) + (2x + 10) = 180
first, to find x:
to simplify (11x - 12) + (2x + 10) = 180, you add the two equations:
13x - 2 = 180
13x = 182
x = 182/13
x = 14
Now, insert the x (which we found that is 14) to each equation.
DEC: (11 x 14 - 12)
= 154 - 12 = 142
m DEC is 142º.
CEF: (2 x 14 + 10)
=28 + 10 = 38
m CEF is 38º.
<em>check: (CEF + DEC = 180º)</em>
<em>38 + 142 = 180 </em>
therefore, the answers are correct :D
Answer:
She will fill the container after 60 times
Step-by-step explanation:
Given data:
15 gallon to be filled
1 quart container
There are 4 quarts in 1 gallon
Therefore 15 gallons will have (4 * 15) quarts = 60 quarts
She will fill the container after 60 times
Answer:
b
Step-by-step explanation:
it isn't c because theres a theorem that says that opposite angles in a parallelogram are congruent
it isn't d because if the opposite angles are 90 and 90 they are supplementary
a is correct, but for the wrong reason
its b
