Answer:
B, C
Step-by-step explanation:
The sums are ...
A) 59.45
B) 118.16
C) 18.97
D) 27.76
Sums B and C have 8 in the ones place.

You can add the ones-place digits. If the resulting ones-digit is 7 or 8, then add the tenths-place digits. If the carry from that sum, added to the sum of ones-place digits, gives a value of 8 or 18, then you found a sum with a ones digit of 8.
Answer:
80
Step-by-step explanation:
7-(5-3(2+6(2^2)))
When a question has multiple signs, the rule of BODMAS is used. That is, Bracket Of Division Multiplication Addition and Subtraction. The question above will therefore be solved in that order.
The first bracket, we have 2^2
That gives 4
Rewriting the question will give
7-(5-3(2+6(4)))
The question in the next bracket will follow
(2+6(4))
In this bracket too, we have the plus sign and the multiplication sign, so the multiplication will first be solved, them addition will follow.
(2+24)
(26)
Rewriting the question again, we have
7-(5-3(26))
And then, we have the last bracket
(5-3(26))
But we have both the Subtraction sign and the Multiplication sign in this bracket also, so the multiplication will first be solved, before the Subtraction.
(5-3(26))
(5-78)
(-73)
And lastly we have
7-(-73)
7+73
80
Answer:
1.6 gallons (so if you can only buy by the gallon, 2 gallons)
Step-by-step explanation:
You divide the total area by how much a gallon covers to get the number of gallons needed.
40/25=1.6
The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
Its 78/10 = 39/5
