Suppose your heart beats 70 times a minute. Combine the time it will take for it to beat 1 million times.

Answers

Answer:

For example, if your heart beats 72 times per minute, 70 beats per minute would give a reasonable estimate. Next find how many days it takes for 1 million heartbeats: 1,000,000 ÷ 100,000 = 10. Thus, 1,000,000 beats take 10 days.

The first part you would add the -1/16 with -11/16 to get an answer of -12/16. Fill in the first blank from the left to be 11 so it is 11/16. The other blank in that row should be a 1 like it is in the original equation.
Second row blank would become 12 because 11+1 =12. The third row of blanks would then simplify 12/16 to be 3/4 because both 12 and 16 can be divided by 4 to make 3 and 4 respectively.
-3/4 + -1/4 equals -1 because -4/4 simplifies to -1.

Which expression represents a simplified form of the algebraic expression shown below?

1/2(2x +4) + x

Question 2 options:

x + 2


2x + 4


2x + 2


3x + 2

Answers

Answer:

2x+2

Step-by-step explanation:

First you want to distribute

1/2(2x+4)

ignore the ending +x for now

Distribute 1/2 to 2x

since 2*1/2 is 1 then we get 1x, or x

next distibute 1/2 to 4

you get +2 since 1/2*4=2

so what you end up with is x+2

However, you still have the +x from the beginning

x+2+x

Imagine that each x has a one in front

1x+2+1x

now re arrange so the common factors are near each other

1x+1x+2

now add the common factors

1x+1x=2x

and finally you get 2x+2

Let the AD be x

Using Pythagorean theorem,

[tex]{p}^{2} + {b}^{2} = {h}^{2} \\

=>{12}^{2} + {x}^{2} = {15}^{2} \\

=>144+{x}^{2}=225\\

Hence,x=AD=9

So,AC=AD+DC=9+16=25.
