Answer:

Below in bold.

Step-by-step explanation:

C1 = 180 - C2

= 180 -  (170-2x)

= 10 + 2x

So B3 = 10+2x (alternate angles).

and B2 = 90 - B3

= 90 - (10 + 2x)

= 80 - 2x.

Answer: THIS IS SO HARD!

Step-by-step explanation:

The required boiling temperature of platinum is 3,739 degrees Celsius.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.

According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,

Boiling temperature of platinum = 4z + 199

So the expression that represents the boiling temperature of platinum in degrees Celsius is:

4z+199

b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:

4z+199 = 4(907)+199 = 3,739

Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

Answer:

1: 55     2: 40

Step-by-step explanation:

For the first problem, by the triangle angle theorm, the three angles in a triangle add up to 180, so

90+35+x=180

125 + x = 180

x = 55

Now, the angle you just found (x = 55) and the exterior angle are supplementary so they also add up to 180

55 + y = 180

y = 125

For the second problem, the two angles in a triangle non-adjacent to the exterior angle are equal to the exterior angle, so

40 + 2x = 3x

x = 40

Answer:

0.03906square foot

Step-by-step explanation:

Given the dimension of the bedroom yo be 2.25in by 2.5in

First we need to convert to foot

2.25in = 0.08333×2.25 = 0.1875feet

2.5in = 0.08333×2.5 = 0.2083feet

Area of the rectangular bedroom = length × width

Area of the rectangular bedroom = 0.1875×0.2083

Area of the rectangular bedroom = 0.03906square foot

Given:

Post office is located at P(1,5).

Market is located at Q(4,9).

To find:

Distance between the post office and the market.

Solution:

Distance between two points is:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The post office is located at P(1,5) and the market is located at Q(4,9). So, the distance between the post office and the market is:

[tex]PQ=\sqrt{(4-1)^2+(9-5)^2}[/tex]

[tex]PQ=\sqrt{(3)^2+(4)^2}[/tex]

[tex]PQ=\sqrt{9+16}[/tex]

[tex]PQ=\sqrt{25}[/tex]

[tex]PQ=5[/tex]

The axes show distance in miles.

Therefore, the distance between the post office and the market is 5 miles.

Step-by-step explanation:

f(x) = x³-1 is the same as y = x³-1

Replace x with y, and y with x =

x = y³ - 1

y³ = x + 1

y = ∛(x+1)

To do this, we simply consider the intervals of the hair lengths where they are lots of data; i.e. where frequency is greater than 1

For the first cluster, we can select the following interval

[tex]\frac{1}{2} \to 2[/tex]

Because;

hair length [tex]\frac{1}{2}[/tex] has a frequency of 3

and the data continues till hair length 2 which has a frequency of 2

For the second cluster, we can select the following interval

[tex]3\frac{1}{2} \to 4\frac{1}{2}[/tex]

Because;

hair length [tex]3\frac{1}{2}[/tex] has a frequency of 3

and the data continues till hair length [tex]4\frac{1}{2}[/tex] which has a frequency of 2

Note that, hair lengths with 0 or 1 as their frequency were not selected as part of the cluster

Answer:

c = 20

Step-by-step explanation:

You have not really asked a question.

I will assume you are asking about the value of c.

The measure of angle 1 is 10 (assuming degrees!), so the measure of angle 2 is 80.  (Complementary angles have measures that sum to 90.)

The measure of angle 2 is also described as 4c, so 4c = 80.  That makes c = 20.

Answer:

MJ = 6.5

Step-by-step explanation:

Tangent lines to a circle are perpendicular to the radius.

tan 68° = JL/3

2.4751 = JL/3

JL = 7.4253

∠JLK = 90° - 68° = 22°

∠MLJ = 61° - 22° = 39°

sin 61° = MJ/7.4253

MJ = 7.4253(0.8746) =  6.5

The length of radius MJ is 5.99 units

Start by calculating the length JL using the following tangent ratio

tan(68°) = JL/3

Make JL the subject

JL = 3 * tan(68°)

Evaluate the product

JL = 7.4

From the figure, the measure of angle MLJ is:

∠MLJ = MLK - JLK

Where:

∠JLK = 90° - 68° = 22°

So, we have:

∠MLJ = 61 - 22

∠MLJ = 39

The radius MJ is then calculated using the following tangent ratio

tan(39) = MJ/JL

This gives

tan(39) = MJ/7.4

Make MJ the subject

MJ = 7.4 * tan(39)

Evaluate

MJ = 5.99

Hence, the length of radius MJ is 5.99 units

Answer:

[tex]525\pi[/tex]

Step-by-step explanation:

Volume of a cylinder is given by the function [tex]v=\pi r^{2}h[/tex]

where v is volume, r is radius and h is height.

In order to find the radius we just divide the diameter in half and get

[tex]\frac{10}{2} =5=r[/tex]

now we just plug the values in the formula

[tex]v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi[/tex]

Answer:

Volume of a cylinder: V = π (r^2) h

Step-by-step explanation:

First, find your radius and your height.

H = 21

D = 10

R = 1/2 d = 5

Then plug them into the equation: V = π (r^2) h

V = π (5^2) 21

V = π (25) 21

V = π (25 x 21)

V = π (525)

V = 525π

Answer:

X = 2

Step-by-step explanation:

-1/2X+4= X+ 1

Add 1/2X to each side

-1/2X+ 1/2 X+4= X+ 1 + 1/2 X

4 = 3/2 X +1

Subtract 1 from each side

4-1 = 3/2 X +1-1

3 = 3/2 X

Multiply each side by 2/3 to isolate x

3 * 2/3 = 3/2 X * 2/3

2 =X
