Answer:
-4
Step-by-step explanation:
Since the total score <em>I</em><em>n</em><em>c</em><em>r</em><em>e</em><em>a</em><em>s</em><em>e</em><em>d</em><em> </em>by eight than the two matching cards must have been -4.
(total of four cards) + (two matching cards) = total score
(total of four cards) + (two cards × -4) = total score
(total of four cards) - 8 = total score
* take away two matching cards by adding 8 on both sides*
(total of four cards) = total score + 8
Answer:
Step-by-step explanation:
∠1 and ∠3 are supplemental
and ∠2 and ∠4 are supplemental
because they are alternate interior angles.
Answer:
yes, this is a reasonable estimate
Step-by-step explanation:
47.81 x 3/11 = 13.04
Answer:
(2pi)/5
Step-by-step explanation:
The cosine function cos(x) has a period of 2*pi.
If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:
5x = 2*pi
x = 2*pi/5
The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.
Answer:
12 1/3
Step-by-step exp
First, you need to add up 11/4 and
6 1/2
11/ 4 + 6 1/2 = 11/4 + 13/2 = 37 / 4
To find how many 3/4 we have in 37/4, we simply dividw 37/4 by 3/4
37/4 ÷ 3/4
= 37/4 × 4/3 (4 will cancel out 4)
= 37/3
=12 1/3
