You stand 100’ from the base of a tower. The tower is 1,058’ tall. What is the angle from where you are standing to the top of t

hodyreva [135]

Answer: 85°

Step-by-step explanation:

Trig functions are remembered by

SOD CAD TOA,

sin = opposite / distance, cos = adjacent / distance, and tan = opposite / adjacent.

Here we have the adjacent side = 100, opposite side = 1058. The tower would fall over if it weren't vertical, and we assume the area is flat and level. So tangent of the answer is 10.58.

We need the angle whose tangent is 10.58.

On Android calculator you swipe left to get the trig functions, tap INV, if RAD is showing tap it to change it to DEG, and tap tan⁻¹. Swipe right and you see tan⁻¹(. Enter 10.58 and the result shows 84.6005606. If it shows 1.47655833 tap the RAD in upper left to change to DEG.

On a 300 point standardized test, Luca earned 82% of the points. How many of the 300 points did Luca earn?

Zina [86]

Answer:

1. He earned 246

82% = 0.82

Move decimal right twice

82 x 300 is 24600

Move decimal left twice

= 246

2. 25

Solve for Y (Total Diamonds)

12 = 48% × Y

12 = $\frac{48}{100}$ × Y

Y = 12 × $\frac{100}{48}$

Y = 12 × 100 ÷ 48

Y = 25

3.80.95%

Solve for "%"

% = 34/42

% = 0.8095 (rounded)

Convert decimal to percent using percent formula:

% = 0.8095 × 100 = 80.95%

A checkers board is eight squares long and eight squares wide. The area of each square is 14 cm². Estimate the perimeter of the

Tamiku [17]

Answer:

Perimeter of the board is 119.7 cm.

Step-by-step explanation:

We are given that,

Area of each square = 14 cm²

i.e. $Side^2=14$

i.e. $Side= \sqrt{14}$

i.e Side = 3.74 cm

So, we get the side of each square is 3.74 cm.

Since, Perimeter of a square = $4a$

→ Perimeter of each square = $4\times 3.74$

→ Perimeter of each square = 14.96 cm

<em>Since, there are 8×8= 64 squares on the board.</em>

Thus, the perimeter of the board = 8 × Perimeter of each square.

i.e. Perimeter of the board = 8 × 14.96

i.e. Perimeter of the board = 119.68 cm

Hence, the perimeter of the board rounded to the tenths is 119.7 cm.

Local income tax defention

mamaluj [8]

Answer:

Local governments in several states impose a local income tax. Local taxes are in addition to federal and state income taxes. Local income taxes generally apply to people who live or work in the locality. As an employer, you need to pay attention to local taxes where your employees work.

If the local income tax is a withholding tax, then you are required to withhold it from employee wages. Or if the local income tax is an employer tax, you must pay it.

Local income taxes are typically used to fund local programs, such as education, parks, and community improvement.
