Answer:
Yes,
Step-by-step explanation:
because two sides are shown equal to each other, a and b. Also two angles are equal to each other, x and y. Once you know two angles or two sides are equal so is the third side.
Another way is SAS (side angle side). There is side a, angle y, and side b. These are shown on both triangles.
Therefore, we can conclude these two triangles are congruent.
The value of $500 after four years is $610
<u>Step-by-step explanation:</u>
It is given that, the value of $500 increases at a rate of 5% per year.
The exponential formula is given by
.
where,
- a is the initial amount.
- b is the growth factor
.
The growth factor b is replaced by either (1 + r) or by (1 - r).
where, r is the rate per year.
b= (1+r) represents the increase in growth rate.
b= (1-r) represents the decrease in growth rate.
Here, the growth rate is increased. So the formula is given by 
where,
- The initial amount, a = 500.
- Rate, r = 5% = 5/100 = 0.05
- Number of years, n= 4.
- y = value of the item after 4 years
<u>To find y value :</u>
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, the value of the item after four years is $610.
If you are asking what the square roots of 121 are and what the square roots of 49 are it is:
11^2=121 and
7^2=49
if, however you're asking what the square roots of 121 divided by 49, I don't know. (this sign '/' is commonly used as a division sign so I'd just want to clarify).
Answer:
The answer is b) 14.7
Step-by-step explanation:
x/0.7 = 21
x = 21(0.7)
x = 14.7
5/4=15/12
1/3=4\12
15+4=19
=19/12= 1 and 7/12
