We have: I = P × R × T / 100
Here, I = 980
P = 7000
T = 8

Substitute their values into the expression:
980 = 7000 × R × 8 / 100
R = 980 × 100 / 7000 × 8
R = 98000 / 56000
R = 1.75%

In short, Your Answer would be 1.75%

Hope this helps!

boyakko [2]

Answer:

It's the first option.

Step-by-step explanation:

It is turned down so the one half is negative (-1/2)

parabola will be in the form of a(x-h)^2 + k. (-h, k) is your vertex, in this case that is (15,25). so in the equation, you will have

-1/2(x-15)^2 + 25. first one.

Hope this helps!

.`. area=x*y
now new length=x+12x/10=22x/10
width=y-y/5=4y/5

The next statements are are;

Statement                                                  {}        Reason

Segment \overline {DC} ≅ Segment \overline {AB}                        {}   CPCTC

\overline {AD} ≅ \overline {BC} and \overline {DC} ≅ \overline {AB}, therefore;

ABCD is a parallelogram                    {}               Parallelogram side theorem

Step-by-step explanation:

Statement                                                  {}        Reason

Segment \overline {DC} ≅ Segment \overline {AB}  by Congruent Parts of Congruent Triangles are Congruent (CPCTC)

Given that \overline {AD} ≅ \overline {BC} and we have that \overline {DC} ≅ \overline {AB}, we get;

ABCD is a parallelogram                    {}               Parallelogram side theorem

The parallelogram side theorem states that a quadrilateral is a parallelogram if it has two pairs or sets of congruent opposite sides.
