seraphim [82]

Answer:

The answer is below

Step-by-step explanation:

We must first define the concepts a little:

We have that when the sides are congruent that is to say that they have the same direction and the same size and also the two opposite sides are parallel, the angles will be the same.

nikdorinn [45]
To ask how much Mr. Perkins will have after 2 years is asking for the total or the "A".

Interest rate (r) - 5% => 0.05

Term / time period (t) - 2 years

Interest (I) - amnt. after everything is multiplied

I = Prt

A = I + P

Interest = 120 × 0.05 × 2

Total = I + 120

Interest = $12

A = 12 + 120

A = $132

Eliza reads \large \frac{1}{7} of her book on Monday. On Tuesday and Wednesday combined, she reads three times as much as she re
lutik1710 [3]

Answer:

Eliza reads a total of 204 pages in the three days combined.

Step-by-step explanation:

From the given information, we are being told that:

Eliza reads \dfrac{1}{7} of her book on Monday.

On Tuesday and Wednesday combined, she reads thrice as much as she read on Monday.

Let assume that; Tuesday = T and Wednesday = W

Then;

T + w = 3 ( \dfrac{1}{7})

The expression to determine the total number of pages is given as:

\large \dfrac{1}{7}r+3\left(\dfrac{1}{7}r\right)

where;

r = total number of pages in the book.

Assuming that Eliza book contains a total of 357 pages. How many pages does she read in the three days combined together.

i.e.

r = 357

Then;

\implies \large \dfrac{1}{7}(357)+3\left(\dfrac{1}{7}(357)\right)

\implies 51+3(51))

\implies 51+153

= 204 pages

Thus, Eliza reads a total of 204 pages in the three days combined.
