Answer:
57 deaths per hour
Step-by-step explanation:
In one year, we have 365 days.
Now, there are 24 hours in a day.
Thus,
Number of hours in one year = 365 × 24 = 8760 hours
Now, since there are half a million heart attacks deaths occurring in the United States of America each year, it means that;
There are 500000 deaths every 8760 hours.
Therefore, death rate per hour = 500000/8760 ≈ 57 deaths per hour
The answer to this question is X= -8
First do the distributive property and you get : -70 + 21x= -238
Then you add 70 to both sides : 21x= -168
Then you divide -168 with 21 and get the answer of -8
Answer:
The slope is 3. The y intercept is 6
Step-by-step explanation:
y=mx+b
m= slope
b= y intercept
Hello there! So, the first thing we do when solving these types of problems is to find the interest rate. Because this is simple interest, the amount earned will be constant. The formula for this is I = prt. The principle is the $2,200. The rate earned per year is 3.4%. 2,200 * 3.4% (0.034) is 74.80. That's $74.80 worth of interest each year. The amount of time is 5.5 years. 74.8 * 5.5 is 411.4. Carmelo will earn $411.40 worth of interest in 5.5 years. However, that's not all. We are looking for the total amount of his bonds, which means add the interest and his initial amount in the bank. 2,200.00 + 411.40 is 2,611.4. Carmelo's saving bonds will be worth $2,611.40 at the end of 5.5 years.
