Answer:

93.7 miles

Step-by-step explanation:

This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.

We need to find the hypotenuse. We can use Pythagoras rule:

hyp^2 = opp^2 + adj^2

where opp = opposite side to the angle considered

adj = adjacent side to the angle considered

This implies that:

x^2 = 60^2 + 72^2\\\\x^2 = 8784\\\\x = \sqrt{8784} \\\\x = 93.7 miles

The car is 93.7 miles far from its starting point.

Can someone help me plzzzz
PSYCHO15rus [73]

Answer:

279 feet

Step-by-step explanation:

To find x, we solve using the Trigonometric function of Tangent

tan θ = Opposite/ Adjacent

θ = 64°

Length of the shadow = Adjacent = 136 feet

Height of the building = Opposite = h

Hence,

tan 64 = h/136 feet

Cross Multiply

h = tan 64 × 136 feet

h = 278.84132245 feet

Approximately, h to the nearest foot ≈ 279 feet

Therefore, the height of the building = 279 feet

If you deposit ₱10,000 into an account that earns 5% annual interest compounded semiannually, how long will it take until there
emmainna [20.7K]

Answer:

t = 3.69 ≈ 3. 7 years

Step-by-step explanation:

Given :

P = 10,000

r = 5%= 0.05

A = 12,000

n = 2 ( because it is compounded semi - annually )

 

  A = P (1 + \frac{r}{n})^{nt}\\

12000 = 10000(1 + \frac{0.05}{2})^{2 t}\\\\1.2 = ( 1 + \frac{0.05}{2})^{2t}\\\\1.2 = (1.025)^{2t}\\\\log \ 1.2 = 2t \ log \ 1.025\\\\2t = \frac{log 1.2 }{log 1.025} \\\\2t = \frac{0.1823}{0.0247}\\\\2t = 7.3805\\\\t = 3.69

X:y = 9:7 Form an equation that links x and y
sleet_krkn [62]

Equations are expressions with equal values

The equation that links x and y is 7x = 9y

<h3>How to determine the equation</h3>

The ratio is given as:

x : y = 9 : 7

Express the ratio, as a fraction

\frac xy = \frac 97

Cross multiply

7 *x = 9 * y

Evaluate the product

7x = 9y

Hence, the equation that links x and y is 7x = 9y
