Answer:

x=1056.25

Step-by-step explanation:

(2x)(2x)(55)=(65)(65)(55) Multiply

4x(55)=232375 Divide 55 from each side

4x=4225 Divide each side by 4

x=1056.25

Answer:

x = 30

Step-by-step explanation:

Since the triangles are similar, that is

ΔABC and ΔDEC

The 3 angles in ΔDEC sum to 180°, thus

∠C + ∠D + ∠E = 180°, that is

55° + 65° + ∠E = 180°

120° + ∠E = 180° ( subtract 120 from both sides )

∠E = 60° and

∠E = ∠B = 2x = 60 ( divide both sides by 2 )

x = 30

The simple interest on a certain sum of money for 2 years at 5% per annum is Rs 320. What will be the compound interest on the s

Brilliant_brown [7]

Answer:

Rs 328

Step-by-step explanation:

Find the principal amount invested.

Simple Interest Formula

I = Prt

where:

I = interest earned
P = principal
r = interest rate (in decimal form)
t = time (in years)

Given:

I = Rs 320
r = 5% = 0.05
t = 2 years

Substitute the given values into the formula and solve for P:

⇒ 320 = P(0.05)(2)

⇒ 320 = P(0.1)

⇒ P = 3200

Compound Interest Formula

$\large \text{$ \sf I=P\left(1+\frac{r}{n}\right)^{nt} -P$}$

where:

I = interest earned
P = principal amount
r = interest rate (in decimal form)
n = number of times interest applied per time period
t = number of time periods elapsed

Given:

P = 3200
r = 5% = 0.05
n = 1 (annually)
t = 2 years

Substitute the given values into the formula and solve for I:

$\implies \sf I=3200\left(1+\frac{0.05}{1}\right)^{2} -3200$

$\implies \sf I=3200\left(1.05\right)^{2} -3200$

$\implies \sf I=3200\left(1.1025\right) -3200$

$\implies \sf I=3528-3200$

$\implies \sf I=328$

Therefore, the compound interest on the same sum for the same time at the same rate is Rs 328.

Two vertical buildings 57 meters apart are 158 meters and 237 meters high. Find the angle of elevation from the top of the short

miskamm [114]

Given :

Two vertical buildings 57 meters apart are 158 meters and 237 meters high.

To Find :

The angle of elevation from the top of the shorter building to the top of the taller building.

Solution :

Distance between height of building, h = 237 - 158 = 79 m.

Distance between these building , d = 57 m.

Now,

$tan\ \theta = \dfrac{h}{d}\\\\tan\ \theta = \dfrac{79}{57}\\\\tan\ \theta = 1.386\\\\\theta = tan ^{-1} 1.386\\\\\theta = 54.19^{\circ}$

Therefore, the angle of elevation from the top of the shorter building to the top of the taller building is 54.19°.

Hence, this is the required solution.

Each calendar will sell for 5 each. Write an equation to model the total income, y, for selling x calendars

OleMash [197]

Answer:

y = 5x

Step-by-step explanation:

If each calendar, x, sells for $5 each, you would multiply 5·x because $5 is how much you earn per calender. Therefore, your total income would be 5 times the number of calendars you sell, or in equation "language", y = 5x
