The result of evaluating 67.8046 + 8.264 - 243.5 is -167.431

The expression is given as:

67.8046 + 8.264 - 243.5

The highest number of significant figures in the expression is 6 (i.e. 67.8046)

This means that the result must be in 6 significant figures.

Next, we evaluate the expression as follows:

67.8046 + 8.264 - 243.5 = -167.4314

Approximate to 6 significant figures.

67.8046 + 8.264 - 243.5 = -167.431

Hence, the result of evaluating 67.8046 + 8.264 - 243.5 is -167.431

Answer:

B

Step-by-step explanation:

In the given figure, the length of BC is 6.66 cm and the length of DC is 5.33 cm

From  the question, we are to determine the length of BC and DC

Considering the diagram,

First, we will determine the measure of angle A

Using SOH CAH TOA

We can write that

[tex]sin A = \frac{4}{5}[/tex]

sin A = 0.8

∴ A = sin⁻¹(0.8)

A = 53.13°

Now, we will determine the measure of angle C

∠A + ∠ABC + ∠C = 180° (Sum of angles in a triangle)

53.13° + 90° + ∠C = 180°

∠C = 180° - 90° - 53.13°

∠C = 36.87°

Also,

Using SOH CAH TOA

[tex]tan C = \frac{BD}{DC}[/tex]

[tex]tan36.87 ^\circ=\frac{4}{DC}[/tex]

[tex]0.7500 = \frac{4}{DC}[/tex]

[tex]DC = \frac{4}{0.75}[/tex]

DC = 5.33 cm

By the Pythagorean theorem,

/BC/² = /BD/² + /DC/²

/BC/² = 4² + 5.33²

/BC/² = 16 + 28.4089

/BC/² = 44.4089

/BC/ = √44.4089

/BC/ = 6.66 cm

Hence, the length of BC is 6.66 cm and the length of DC is 5.33 cm

Answer:

14π cm

Step-by-step explanation:

Circumference of a circle given the diameter is :

πd

We simply substitute the value given in the image into our formula to find our answer:

πd = π×14 = 14π

Units will be cm as circumference is a length

This is our final answer as the question states to leave it in pi form .

Hope this helped and brainliest please

Answer:

14π cm

Step-by-step explanation:

Circumference of a circle with radius r = 2πr or 2rπ

The diameter d is twice the radius so circumference = dπ

Here d= 14 so the answer is 14π cm

The area of the equilateral, isosceles and right angled triangle are 12.6mm², 9.61in² and 16.81yds² respectively.

Note that:

The area of an Equilateral triangle is expressed as A = ((√3)/4)a²

Where a is the dimension of the side.

The area of an Isosceles triangle is expressed as A = (ah)/2

Where a is the dimension of the base and h is the height.

The area of a Right angled triangle is expressed as A = (ab)/2

Where a and b is the dimension of the two sides other than the hypotenuse.

For the Equilateral triangle.

Given that;

A = ((√3)/4)(5.4mm)²

A = ((√3)/4)( 29.16mm² )

A = 12.6mm²

Area of the Equilateral triangle is 12.6mm²

For the Isosceles triangle.

Given that;

The height h is the imaginary line drawn upward from the center of a.

First, we calculate the height using Pythagorean theorem

x² = y² + z²

Where x = b = 5.9in, y = a/2 = 3.4in/2 = 1.7in, and z = h

(5.9in)² = (1.7in)² + h²

34.81in² = 2.89in² + h²

h² = 34.81in² - 2.89in²

h² = 31.92in²

h = √31.92in²

h = 5.65in

Now, the area will be;

A = (ah)/2

A = (3.4in × 5.65in )/2

A = 19.21in²/2

A = 9.61in²

Area of the Isosceles triangle is 9.61in².

For the Right angled triangle

Given that;

A = (ab)/2

A = ( 8.2yds × 4.1yds)/2

A = ( 33.62yds²)/2

A = 16.81yds²

Area of the Right angled triangle is 16.81yds²

Therefore, the area of the equilateral, isosceles and right angled triangle are 12.6mm², 9.61in² and 16.81yds² respectively.

The total length of the trip 190.08 miles

How you do it is to add the 44% of 132 to 132

= (132 + (132×44%))

Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived.

First, you have to find out how much 44% is. Change it into decimal form (0.44) and then multiply the two together.

132 × 0.44 is 58.08 miles.

Then you add that to the rest of the trip, 132 miles.

Answer:

  1.962×10^8 cm

Step-by-step explanation:

The area and perimeter formulas can be use to find the perimeter of this rectangle, given its area and the length of one side.

  A = LW

  P = 2(L +W)

__

Solving the area formula for width, we have ...

  W = A/L

Using that in the perimeter formula, we find the perimeter to be ...

  P = 2(L +W) = 2(L +A/L)

Using the given values for area and length, we find the perimeter is ...

  P = 2(9.2×10^7 +5.612×10^14/(9.2×10^7)) = 1.962×10^8 . . . cm

The perimeter of the rectangle is 1.962×10^8 cm, or 1962 km.

_____

Additional comment

The width is 6.1×10^6 cm, or 0.61×10^7 cm. Then the sum of length and width is (9.2 +0.61)×10^7 = 9.81×10^7 cm. The perimeter is twice that, or 19.62×10^7 cm = 1.962×10^8 cm. 1 km = 10^5 cm, so this is 1.962×10^3 km, or 1962 km.
