Answer:

Solving for x;

2x + 85 + 5x + 29 = 930

combine like terms:

7x + 114 = 930

-114          -114

7x = 816

/7      /7

x = 116.57, now we replace the x with it's actual value:

∠ZT = 2(116.57) + 85 = 318.14°

∠ZV = 5(116.57) + 29 = 611.85°, lets double check if they both equal 930;

318.14 + 611.85 = 929.99, which is close to 930 so we are correct.

Answer:

No, it can not.

Step-by-step explanation:

For a triangle to exist. The two sides of length of every triangle added up must be greater than the other length.

Here,

13 + 3 > 10

13 + 10 > 3

but,

3 + 10 > 13 is false

so, the side lengths 3, 10, 13 can not form a triangle.

Answer:

  0.57 inches

Step-by-step explanation:

To find the quantity, multiply the rate by the time.

  (0.057 in/min) × (10 min) = 0.57 in

At the given rate, 0.57 inches fell in 10 minutes.

Answer:

a)

[tex]8(x + 5)[/tex]

b)

[tex]13y + 10[/tex]

Step-by-step explanation:

Answer:

(a) 1st, 2nd

(b) 4th

Step-by-step explanation:

(a) Option 1: Expanding with the distributive property, we have

[tex]8(x+5)=8x+8\cdot 5\\~~~~~~~~~~~~=8x+40,[/tex]

which is equivalent.

Option 2: Multiplying the terms gives

[tex]8\cdot x+8\cdot 5= 8x+40[/tex],

which is equivalent.

Option 3: We don't know what x is, so there is no way to write [tex]48x[/tex] as [tex]8x+40[/tex]. This is not equivalent.

Option 4: Expanding with the distributive property gives

[tex]8(5x+1) = 8\cdot 5x+8\cdot1\\~~~~~~~~~~~~~=40x+8,[/tex]

which is not equivalent.

(b) First, we combine like terms in the given expression:

[tex]12+14y-2-y=12-2+14y-y\\~~~~~~~~~~~~~~~~~~~~~~~=10+(14-1)y\\~~~~~~~~~~~~~~~~~~~~~~~=10+13y.[/tex]

Looking at the given answer choices, only the fourth option is equivalent.

Step-by-step explanation:

The value of cosθ from the trigonometric identity is equal to -21/29

Data;

This formula is used to find the missing side of a right angle triangle.

This is given as

[tex]hypothenuse^2 = adjacent^2 + opposite^2[/tex]

But in trigonometric ratio, the sine ratio is

[tex]sin \theta = \frac{opposite}{hypothenuse}[/tex]

This implies that

Let's find the adjacent using Pythagorean theorem

[tex]x^2 = y^2 + z^2\\29^2 = 20^2 + z^2 \\z^2 = 29^2 - 20^2\\z^2 = 441\\z = \sqrt{441} \\z= 21[/tex]

Now that we know the value of adjacent,

The value of cos(0) will be

[tex]cos \theta = \frac{adjacent}{hypothenuse} \\cos \theta =- \frac{21}{29}\\[/tex]

Note: The negative sign in front of the ratio indicates the fact that in the second quadrant, only sine theta is positive, the rest are negative.

The value of cosθ is equal to -21/29

Considering the volume of a rectangular prism, it is found that the volume of the wooden mold is given by:

In this problem, the wooden mold is composed by two rectangular prisms:

Hence the volume in cubic inches is given by:

[tex]V = 25(10)(12) + 20(12)(12) = 5880[/tex]

Rounding, it is closest to 6000 in³, hence option C is correct.

Answer:

y = - 3x - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 10 - 3x = - 3x + 10 ← is in slope- intercept form

with slope m = - 3

y = - 6x - 4 ← is in slope- intercept form

with y- intercept c = - 4

then equation of required line is

y = - 3x - 4

Hello!

The slope of the first line is -3.

The y-intercept of the second line is -4.

How did I identify the slope & y-intercept?

Let me share my "secret"

Well, both equations are written in slope-intercept form (y=mx+b)

where m = slope & b = y-intercept.

Now you know ;-)

Anyway, the new line should have the same slope as the first line (-3)

And the y-intercept of the second line is -4.

So the equation is

y=-3x-4

Hope everything's clear!

The height of the tree to the nearest tenth of foot is 20.5 ft

A right angle triangle has one of its angles as 90 degrees. The sides can be found using Pythagoras theorem.

The side of the base triangle can be found using Pythagoras theorem.

c² = a² + b²

c² = 9.2² + 5.8²

c² = 84.64 + 33.64

c = 10.9 ft

using similar triangle ratio,

5.8 / 10.9 = 10.9 / x + 5.8

5.8x = 118.81 - 33.64

x = 85.17 / 5.8

x = 14.6844827586

x = 14.7 ft

The height of the tree to the nearest foot is  14.7 + 5.8 = 20.5  ft

Step-by-step explanation:

The domain is all of the numbers that the graph is on, over the x-axis. Looking at the x-axis, the graph only spans across 0-170, so the answer would be   a.) Domain: all numbers from 0 to 170.

The range is all of the numbers that the graph is on, over the y-axis. Looking at the y-axis, the graph only spans across 0-60, so the answer would be   d. Range: all numbers from 0 to 60.

Answer:

[tex](A)\frac 1 {cosx} \frac 1 {sin x} - \frac {cosx} {sin x} = \frac {sin x} {cosx} \\\\(B)\frac{1-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(C) \frac{(sin^2x + cos^2x)-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(D) \frac{sin^2x }{cos x sin x} = \frac {sin x} {cosx}\\\\(E)\frac {sin x}{cos x} = \frac {sin x}{cos x}[/tex]

In step A, you replace all trigonometric functions with their definitions in terms of sine and cosine.

In step B, you add the two together as you add fractions.

In step C, you replace 1 with the sum of the squares of sine and cosine.
In step D, you add the cosine terms together so they disappear.

In step E, finally, you divide numerator and denominator by [tex]sin x[/tex].
