Step-by-step explanation:
First we get the same denominator by finding a common multiple.
20 is the lowest common multiple so let's use that.
9/10 will have to change so that the denominator is 20.
From 10 to 20 we have multiplemultiplied it by 2 so we will do the same to the numerator.
9 × 2 = 18.
The fraction is now 18/20.
Now 3/4 – we will get to 20 by multiplying by 5.
3 × 5 = 15
Now we can compare
18/20 and 15/20
9/10 and 3/4
In this item, we let x be the amount that is deposited in the account that has a simple interest equal to 7%. With this representation, the amount that is deposited in the account with simple interest of 6% is equal to 12000 - x.
The amount of interest earned from the investment is calculated through the equation,
I = P x (i)
For the first investment,
I = (x)(0.07)
For the second investment,
I = (12000 - x)(0.06)
Adding up the interests,
800 = 0.07x + (0.06)(12000 - x)
The value of x from the equation is 8000.
<em>Therefore, the amount invested to that with 7% interest is $8000 and the amount invested to that with 6% interest is $4,000.</em>
Answer:
B. 200
Step-by-step explanation:
A perfect square is the multiplication of two equal integers such as 1*1=1, 2*2=4, 3*3=9. From the examples, 1, 4, 9 are perfect square.
Non perfect square numbers are 1*2=2,
3*1=3,
5*1=5,
3*2=6,
6*1=6,
7*1=7
Examples of perfect squares:
1*1=1
2*2=4,
3*3=9,
4*4= 16,
5*5=25,
6*6=36,
7*7=49,
8*8=64,
9*9=81,
10*10=100,
11*11=121,
12*12=144,
13*13=169,
14*14=196,
15*15=225 and so on
The 50-20-30 savings rule is a simple plan that helps people on managing their money.
It states that over your total after-tax earnings, 50% should be spent on your needs and obligations. 20% should be spent on savings and debt payments, and 30% on whatever else you like.

PQ and QR are congruent (given)
QS and SQ are congruent (Reflexive Property)
∠PQS and ∠RQS are congruent (again, Reflexive Property)
Note: It is not SSS, becase we do not have the information (yet) to state that PS is congruent with RS
hope this helps
