Answer:

Step-by-step explanation:

The only two numbers that would make the whole expression divisible by 8 are 0 and 8. Since the number also has to be divisible by 5, though, the last digit must be a 0 or a 5. Therefore, A=0. Hope this helps!

URGENT HELP ASAP, PLEASE HELP WITH MY GRADE 11 MATH!

Half-Life Formula:

Amount remaining = (Initial amount)[ (1/2)^(time / half-life) ]

Amount remaining = ?

Initial amount = 200 mg

Time = 2 hours = 120 minutes

Half-Life = 20 mins

---Notice that I changed the time from hours to minutes. The time and half-life time need to be in the same unit.

A = (200)[ (1/2)^(120/20) ]

A = (200)(1/2 ^6)

A = (200)(1/64)

A = 3.125

Answer: 3.125 mg remain

Hope this helps!

Find the area of the triangle.

Ne4ueva [31]

Answer:

10.92cm

Step-by-step explanation:

We can solve this problem by taking the formula to the area of a triangle and substituting our given numbers with the variables in it.

$A = \frac{1}{2}bh$ , where $b$ represents base and $h$ represents height.

So, if we substitute our given measurements with the variables in this formula, we can easily solve this.

$A = \frac{1}{2}(2.8)(7.8)$

Then, using the order of operations, we multiply and ultimately solve this problem.

$\frac{1}{2}*2.8 = 1.4$

$1.4*7.8=10.92$

Thus, our answer is 10.92cm.

What is the value of the expression |a + b| + |c| when a = –5, b = 8, and c = –13?

nasty-shy [4]

|a+b| + |c| when a= -5, b= 8, c= -13:

|-5+ 8|+ |-13|
= |3|+ 13
= 3+ 13
= 16

The correct answer is D. 16~
