A triangle with side lengths of 200 meters, 300 meters, and 250 meters is shown. a surveyor measures the lengths of the sides of a triangular plot of land. what is the measure of the angle of the triangular plot at which the surveyor stands? approximate to the nearest degree. cos–1(0.75) = 41° cos–1(0.125) = 83° cos–1(0.563) = 56° cos–1(0.15) = 89°

Answers

Answer 1

The angle of the triangular plot at which the surveyor stands is 83°

What is a triangle?

A triangle is a shape with three sides and three angles. From the information given, the sides of the three angles are different, we can say the triangle is a scalene triangle since no sides are equal.

To determine the angle of the triangular plot at which the surveyor stands, we need to use the cosine formula.

Given that:

a = 300 mb = 250 mc = 200 m

Let's assume that the angle at which the surveyor stands is ∠A, then:

[tex]\mathbf{a^2= b^2+c^2-2 bc \times Cos A}[/tex]

Making cos A the subject, we have:

[tex]\mathbf{cos \ A = \dfrac{ b^2+c^2-a^2}{2bc}}[/tex]

[tex]\mathbf{cos \ A = \dfrac{ 250^2+200^2-300^2}{2(250 \times 200)}}[/tex]

[tex]\mathbf{cos \ A = 0.125}[/tex]

A = cos⁻¹ (0.125) ≅ 83°

a packaging designer wants to find how much fabric is needed to cover the jewelry box shown the box is 12cm shown 4 cm wide and 5m high find the surface area of the box

Answers

Step-by-step explanation:

I guess you mean it is

12 cm long, 4cm wide and 5 cm high.

and the fabric goes outside on the box ? strange, but ok.

a box (like a die) has 6 sides in the form of 3 pairs of equal rectangles :

top-bottom, left-right, front-back

the surface area is the sum of all 6 rectangles.

top-bottom :

2 × 12×4 = 2 × 48 = 96 cm²

left-right :

2 × 4×5 = 2 × 20 = 40 cm²

front-back :

2 × 12×5 = 2 × 60 = 120 cm²

in total

120 + 40 + 96 = 256 cm²

Find the area of the shaded sector. round to the nearest tenth. Please help!!

Answers

Answer:

Step-by-step explanation:

Remark

If the entire circle was shaded the radius sweeping out the circle would go through 360 degrees.

So the way to solve this problem is to multiply the entire area of the circle by (81/360)

Area of the sector = (81/360) * pi * r^2

pi = 3.14

r =8.91 cm

Area of the sector = (81/360) * 3.14 * 8.91^2

Area of the sector = 56.09

Rounded to the nearest tenth, the answer is 56.1

Using factoring, what is the solution to the equation 2x2 + 3x – 5 = 0

Answers

Here if this helps your welcome if not I’m sorry

So start with

2x2+3x-5=0

2x2=4

4+3x-5=0

Subtract 4 from both sides

4+3x-5=0
-4. -4

The 4 cancels out

3x-5= -4

Now add 5 to each side and the 5 will cancel

3x-5=-4
+5. +5

3x=1

Divide 3 from both sides the 3 cancels

3x=1

3/3x= 1/3

So your answer is:

In 1983, a winter hat cost $12.95. today, a winter hat costs $24.50. if the cpi is 219, what is the percent relation of the actual price of a winter hat to the expected price? a. the actual price is 39.3% higher than the expected price. b. the actual price is 15.8% higher than the expected price. c. the actual price is 13.6% lower than the expected price. d. the actual price is 29.8% lower than the expected price.

Answers

The actual price is 13.6% lower than the expected price.

What is cpi?

CPI or Consumer Price Index is a measure of determining retail inflation in an economy, based on price variations in a fixed basket of goods and services, over overtime periods.

Let's suppose the expected price is x.

The percent relation of the actual price of a winter hat to the expected price is given by;

CPI = ( expected price ) : ( price in 1983 ) × 100

219  =  ( x  : 12.95 ) × 100

Divide both sides by 100.

x : 12.95 = 2.19

x =2.19 × 12.95

x = $28.36 ( expected price )

p = ( 24.50 × 100 ) / 28.36

p= 2450/28.36

p = 86.4 %

100 % - 86.4 % = 13.6 %

Hence, the actual price is 13.6% lower than the expected price.

if a rectangle has a perimeter of 18 cm, and a height of 4 cm, what is the area?

Answers

20 cm²

Step-by-step explanation:

Look at the diagram attached.

If the height is 4cm, we will have two sides that are 4cm for our rectangle.

We can label the other sides as x.

They are both x since opposite sides of a rectangle are equal in length.

We can make an equation with our perimeter:

[tex]2(4) + 2(x) = 18\\8 + 2x = 18\\2x = 10\\x = 5[/tex]

Square pyramids A and B are similar. In pyramid​ A, each base edge is 20 cm. In pyramid​ B, each base edge is 5 cm and the volume is 25 cm.
a. Find the volume of pyramid A.
b. Find the ratio of the surface area of A to the surface area of B.
c. Find the surface area of each pyramid.

Answers

Answer:

Below in bold.

Step-by-step explanation:

a) The volumes will be in the ratio of the cubes  of the edges.

So volume of A / volume B = 20^3 / 5^3

Volume A / 25 = 8000/125

Volume a = (25* 8000) / 125

= 8000/ 5

= 1600 cm^3.

b) ratio of the surface area of A to surface area of B

=  20^2 : 5^2

= 400:25

= 16:1.

c. The volume of pyramid B is 25 cm*3 so it' height is  25 / area of its base = 25/5^2

= 1 cm.

Now its slant height = √(1^2 + (2.5)^2)

= √7.25

= 2.6926 cm

So surface area = 25 + 4 * 1/2 * 5 * 2.6926

= 51.926

= 51.93 cm^2 to nearest hundredth.

and the surface area of pyramid B = 51.926 * 16

= 830.82 cm^2 to nearest hundredth.
