Find an equivalent expression to y + 4 + 3 (y + 2) please answer today

on a trip, you had to change your money from dollars to British pounds. you got 560 pounds for 800 dollars. which is a unit rate

Bond [772]

1pound is 800/560......which is 80/56-->10/7
so 1 pound is 10/7 dollars....
because you don't say for one dollar it is this many pounds.
also for unit rate i divide by 560 on both sides to get one pound on one side and then how many dollars on the other

From his eye, which stands 1.61 meters above the ground, Jacob measures the angle

bixtya [17]

Step-by-step explanation:

we have a right-angled triangle, that is "hovering" 1.61 m above the ground.

the Hypotenuse (the side opposite of the 90 degree angle) is the line of sight from the eye to the top of the skyscraper.

one leg is the height of the skyscraper (minus the 1.61 m).

the other leg is the ground distance from Jacob to the skyscraper (281 m).

we know already 2 angles : the 90° angle between the ground distance and the skyscraper height. and the 25° between the ground distance and the line of sight.

and as we know that the sum of all angles in a triangle is always 180°, we know that the third angle (between the line of sight and the skyscraper height) is

180 - 90 - 25 = 65°

now we can use the law of sines

a/sin(A) = b/sin(B) = c/sin(C)

(the ratio between a side and its opposing angle)

to get all missing side lengths.

the 25° angle is opposite of the skyscraper height, and the 65° angle is opposite of the ground distance (the only side length we know so far).

so,

height/sin(25) = 281/sin(65)

height = 281 × sin(25)/sin(65) = 131.0324519... m

to get the full height of the skyscraper, we need to add the 1.61 m that the described triangle was "hovering" above ground.

therefore, the height of the skyscraper is

131.0324519... + 1.61 = 132.6424519... ≈ 132.6 m

An amount of 19,000 is borrowed for 7 years at 7.75% interest, compounded annually. If the loan is paid in full at the end of th

Kruka [31]

Answer:

The Amount paid back after 7 years is Rs 32,038.674 .

Step-by-step explanation:

Given as :

The loan amount borrowed = p = Rs 19,000

The rate of interest applied = r = 7.75% compounded annually

The time period of loan = t = 7 years

Let The Amount paid back after 7 years = Rs A

<u>Now,From Compound Interest method</u>

Amount = Principal × $(1+\dfrac{\texrm rate}{100})^{\textrm time}$

Or, A = p × $(1+\dfrac{\texrm r}{100})^{\textrm t}$

Or, A = Rs 19,000 × $(1+\dfrac{\texrm 7.75}{100})^{\textrm 7}$

Or, A = Rs 19,000 × $(1.0775)^{7}$

Or, A = Rs 19,000 × 1.686246

∴ A = Rs 32,038.674

So, The Amount paid back after 7 years = A = Rs 32,038.674

Hence, The Amount paid back after 7 years is Rs 32,038.674 . Answer
