Answer:
The additional deposit to be made in one year should be $ 301.81.
Step-by-step explanation:
Given that I need to save $ 1,300 to go overseas in two years, and I deposit $ 800 in a savings account today, that earns 10% interest, and I will make an additional deposit in one year, to determine how much must I deposit in one year in order to have enough to go on the trip, the following calculation must be performed:
800 x 1.1 = 880
(880 + X) x 1.1 = 1300
1300 / 1.1 = 1,181.81
1,181.81 - 880 = X
301.81 = X
Therefore, the additional deposit to be made in one year should be $ 301.81.
Can you please say how many snow globes there are so, we can give you an answer?
Answer:
Part 1) The length of the longest side of ∆ABC is 4 units
Part 2) The ratio of the area of ∆ABC to the area of ∆DEF is
Step-by-step explanation:
Part 1) Find the length of the longest side of ∆ABC
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
The ratio of its perimeters is equal to the scale factor
Let
z ----> the scale factor
x ----> the length of the longest side of ∆ABC
y ----> the length of the longest side of ∆DEF
so
we have
substitute
solve for x
therefore
The length of the longest side of ∆ABC is 4 units
Part 2) Find the ratio of the area of ∆ABC to the area of ∆DEF
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of ∆ABC
y ----> the area of ∆DEF
we have
so
therefore
The ratio of the area of ∆ABC to the area of ∆DEF is
I believe the answer would be B
-3x4=-12
9+-12=-4
So the y-intercept is -4
Since you already know the gradient you can form:
y = -3x -4
