LT1 10th grade level. How tall I’d the building?

Answers

Answer 1

Answer: 99.2 m

Step-by-step explanation:

Given

The height of the flagpole is 35 m which is situated at 60 m

It is clear that the angle of elevation for the flagpole and building is the same, let say [tex]\theta[/tex]

from the figure, we can write

[tex]\Rightarrow \tan \theta=\dfrac{35}{60}=\dfrac{h}{170}\\\\\Rightarrow h=170\times \dfrac{35}{60}\\\\\Rightarrow h=99.166\approx 99.2\ m[/tex]

Thus, the height of building is 99.2 m

What is the solution to this system of equations?

Answers

Answer:

(2, 6).

Step-by-step explanation:

The solution is the ordered pair where the 2 lines intersect.

Answer:

(2, 6)

Step-by-step explanation:

Take a look at the graph.

The problem has rather helpfully graphed out the two equations presented to us, and the point in which both lines intersect is (2, 6), making this pair your solution.

If you'd like to check, plug in the corresponding variables.

x = 2

y = 6

First equation:

y = x + 4

6 = 2 + 4

6 = 6

The equation is true.

Second equation:

y = -0.5x + 7

6 = (-0.5 x 2) + 7

6 = -1 + 7

6 = 6

This equation is true as well.

The price of gas went up by 0.5% last month.
Suppose gas currently costs $2.44 a gallon.

If the price of gas continues to increase at this rate, what will it cost on year from now?

Answers

The gas will cost $8.44 in a year

If price of gas went up by 0.5% last month. Suppose gas currently costs $2.44 a gallon. If the price of gas continues to increase at this rate then 2.5864 cost on year from now

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

0.5% convert to decimal

0.5/100=0.005

We need to calculate what is 0.5 percentage of 2.44.

0.005×2.44=0.0122

The cost increases after one year i.e is twelve months.

0.0122×12=0.1464

Now add 0.1464 with 0.0122

2.44+0.1464

Two point five eight six four.

=2.5864

Hence 2.5864 is the price of gas after one year.

Answers

Answer:

V = 497.8 cm^3

Step-by-step explanation:

Thats Righttt

The volume of the cone is 1592.6 cm³

What is volume?

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

The right circular cone's vertex is immediately above the base's centre. The line connecting the vertex with the centre point of the base is perpendicular to the cone's radius. A cone, on the other hand, can have its vertex anywhere.

Given that, a right circular cone with the height of 19.4 cm and a base with a diameter of 9.9 cm. we need to find the volume,

Volume of cone = 1/3 × π × radius² × height

= 1/3 × 3.14 × (9.9/2)² × 19.4

= 1592.6 cm³

Hence, the volume of the cone is 1592.6 cm³

height for the building = 551.8 ft

Step-by-step explanation:

The info given describes the shape of a right triangle.

Thus:

Reference angle = Angle of elevation = 23°

Opposite side = height of the building = ?

Adjacent side = 1,300 ft

Apply trigonometric function, TOA:

Tan 23 = Opp/Adj

Tan 23 = Opp/1,300

1,300 × Tan 23 = Opp
