Answer: 2 and 17/20 mm is the total thickness of the stack.
Step-by-step explanation:
Get the values you need for the dime and the penny from the chart:
dime: 1 and 7/20mm , penny: 1 and 1/2mm
Find common denominators for the fractions given in the chart.
20 will work because 1/2 is the same as 10/20.
Add the numerators of the fractions: 7 + 10 = 17 so the fraction will be 17/20
Add the whole numbers 1 + 1 = 2
Put it all together and now you've got 2 and 17/20 mm
Answer:
ABD= 58
BDC= 32
Step-by-step explanation:
complementary = 2 angles equal 90 degrees.
8y+2=90
Subtract 2 both sides.
8y=88
y=11
That's not all, put y into the equations.
ABD
5(11)+3
Multiply
55+3=58
BDC
3(11)-1
MULTIPLY
33-1
SUBTRACT
32
Answer:
A
Step-by-step explanation:
That's the formula for the solution of a quadratic equation, like this:
The formula is:
In your case:
The only answer that has c = -2 is the first one, A.
If you move the 5 to the left-hand side, it becomes -5 and with the +3 gives a -2.
7*8-6+5=55
6*5+7+8=45
5*7+8+6=49
