Todd's cube has an edge that measures5 inches. Kara's cube has an edge of3 inches. If Kara's cube was stackedon top of Todd's cube, what wouldbe the total volume of the combinedsolid? ?
Answers
Answer:
152 in³
Step-by-step explanation:
Each cube's volume is the cube of its edge length, so the total volume is ...
(5 in)³ + (3 in)³ = 125 in³ +27 in³ = 152 in³

The average heart beat in a lifetime is 2,365,200,00 beats.
Given that,
An average human heart beats 60times per minute.
If an averageperson lives to the age of 75.
We have to determine,
How many times does the averageheart beat in a lifetime.
According to the question,
An average human heart beats 60 times per minute.
And there is 60 beats in a minute and 60 minutes in an hour,
Then,
Heart beat per hour = 60 beats × 60 minutes = 3,600 beats per hour.
Then,
The amount of beats in an hour by the number of hours in a day.
Heart beats per day = 3600 × 24 hours = 86,400 beats per day
Then,
The number of days in a year is 365 in a year, but use the flat rate of 365 since that is generally the accepted answer.
Heart beat per year = 86,400 × 365 days = 31,536,000 beats per year
Therefore,
An average person lives to the age of 75,
Heart beat in a lifetime to age of 75 years,
= 31,536,000 × 75 years = 2,365,200,00 beats in a lifetime.
Hence, The average heart beat in a lifetime is 2,365,200,00 beats.

Answer:
The average number of beats in a lifetime would be 2,365,200,000
Step-by-step explanation:
To find the amount we need to take basic steps. The first step is multiplying the number of beats to find out how many are in an hour. Since there are 60 in a minute and 60 minutes in an hour, multiply the two.
60 beats * 60 minutes = 3,600 beats per hour.
Now multiply the amount of beats in an hour by the number of hours in a day.
3,600 * 24 hours = 86,400 beats per day
Now multiply the number of days in a year. Technically there is 365 1/4 in a year, but we'll use the flat rate of 365 since that is generally the accepted answer.
86,400 * 365 days = 31,536,000 beats per year
And now we take that number and multiply by the number of years that he lines
31,536,000 * 75 years = 2,365,200,00 beats in a lifetime

in a rectangle, all angles are 90 degrees and the diagonals are equal
meaning the diagonals bisect each other, they cut in equal halves
so. those two sides are equal, and thus they make up an isosceles triangle
on the sides
if those two sides are equal, the angles they make on the other side are equal
so if angle D is 55 degrees, angle A is 55 degrees
and the missing angle is 180 - (55 + 55) or 70
that's just the left-side
now, angle "x" on the right side, is a vertical angle of that angle on the left,
and vertical angles are equal, thus x = 70
