Answer:

A geologist had to rocks on a scale that weighed 3.3 kg together the first rock was 0.3 of the total weight how much did each Rock weigh?

First thing you have to do is take 3.3 and multiply it by 0.3, that gives you 0.99. And just take the 0.99 and subtract 3.3 by 0.99. that gives you your ANSWER(2.31 kg) Hope that helps!

Step-by-step explanation:

To solve the problem, we first find the weight of the first rock by multiplying the total weight of the rocks by 0.3, then subtract the weight of the first rock from the total weight to find the weight of the second rock. The first rock weighs 0.99 kg and the second rock weighs 2.31 kg.

The problem involves understanding proportions since the first rock weighs 0.3 of the total weight. First, let us find the weight of the first rock. Multiply the total weight of the rocks, which is 3.3 kg, by 0.3 to find the weight of the first rock. That is 3.3 kg * 0.3 = 0.99 kg.

Next, subtract the weight of the first rock from the total weight to find the weight of the second rock. That is 3.3 kg - 0.99 kg = 2.31 kg. So, the first rock weighs 0.99 kg while the second rock weighs 2.31 kg.

Step-by-step explanation:

Answer:

Let x represents the number of apple tree and y represents the number of pear tree and z represents the number of cherry tree in an orchard.

From the given statement: The number of apple trees is 8 more than twice the number of pear trees.

⇒ [tex]x = 2y + 8[/tex]                         .....[1]

Also, It is given that the number of cherry and pear trees combined is 11 more than the number of apple trees.

⇒[tex]y + z = x + 11[/tex]                    ......[2]

The farmer plants 143 trees total.

⇒[tex]x +y +z =143[/tex]                        .....[3]

Substitute equation [2] into [3] we get;

[tex]x + x + 11 = 143[/tex]

Combine like terms;

[tex]2x +11 = 143[/tex]

Subtract 11 on both sides we get;

2x + 11 -11 =143 -11

Simplify:

2x = 132

Divide both sides by 2 we get;

x = 66

Substitute the value of x in equation [1];

66 = 2y + 8

Subtract 8 on both sides we get;

[tex]66 -8 =2y + 8 -8[/tex]

Simplify:

58 = 2y

Divide by 2 on both sides we get;

y = 29

Substitute the value of x and y in equation [3];

we have;

29 + 66 + z = 143

95 + z =143

Subtract 95 on both sides, we get;

95+ z -95 = 143- 95

Simplify:

z = 48

The framer plant in the orchard =  66 apple trees , 29 pear trees and 48 cherry trees

Step-by-step explanation:

The measurement representing the largest volume among the options is D) 1.02 L, as it is larger than .99 L, 0.999 L and 0.998 L, which are the rest of the options converted into the same unit (liters).

In order to determine which of these measurements represents the largest volume, we need to make sure we're comparing them using the same units of measure. So, we'll convert everything to liters (L), as this is the most common unit among the options.

First of all, A) 999 milliliters (mL) is equal to 0.999 Liters (L) because 1 L = 1000 mL. B) .99L is just .99L. For C) 998 cubic centimeters (cm³), we need to know that 1 cm³ is equal to 1 mL, so 998 cm³ equals 0.998 L. Finally, D) 1.02 L is already in liters.

Looking at these conversions, D) 1.02 L represents the largest volume among the given choices.

Answer:

(-3,3)

Step-by-step explanation:

3x=36-15y and 11x =-78+15y

We move all x  and y terms to the left hand side of the equation , so that we can apply elimination method

3x=36-15y , Add 15 y on both sides , 3x + 15y = 36

11x =-78+15y, subtract 15y on both sides, 11x -15y = -78

Now we add both equations

3x  + 15y = 36

11x -15y = -78

------------------------

14x  = -42

divide both sides by 14

x= -3

Now Plug in -3 for x in any one of the given equation

3x=36-15y

3(-3) = 36 - 15y

-9 = 36 - 15y

Subtract 36 on both sides

-45 = -15y

Divide both sides by -15

So y= 3

Answer:

1.) 64

2.) x= -5+4i and x= -5-4i

3.) (4x+3iy)(4x-3iy)

Answer:

When we are completing squares, we need to divide by 2 the linear term and then find its square power, that's the term we need to add on both sides of the equality, as follows

[tex](\frac{16}{2})^{2} =(8)^{2}=64[/tex]

Basically, we need to add the number 64 both sides

[tex]x^{2} +16x+64=18+64[/tex]

The given equation is

[tex]x^{2} +10x+41=0[/tex]

We need to apply the quadratic formula to solve this equation

[tex]x_{1,2} =\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

Where [tex]a=1[/tex], [tex]b=10[/tex] and [tex]c=41[/tex]. Replacing these values, we have

[tex]x_{1,2} =\frac{-10(+-)\sqrt{10^{2}-4(1)(41) } }{2(1)}\\x_{1,2} =\frac{-10(+-)\sqrt{100-164 } }{2}=\frac{-10(+-)\sqrt{-64} }{2}[/tex]

There we need to use complex number, to transform the subradical number in a positive number

[tex]x_{1,2}=\frac{-10(+-)\sqrt{64}i }{2}=\frac{-10(+-)8i}{2}\\ x_{1,2}=-5(+-)4i[/tex]

Therefore, the complex solutions are

[tex]x_{1}=-5+4i\\ x_{1}=-5-4i[/tex]

The given expression is

[tex]16x^{2} +9y^{2}[/tex]

To solve this expression, remember that [tex]i=\sqrt{-1}[/tex]

First, we expresse both squares uniformly,

[tex]16x^{2} +9y^{2}=(4x)^{2}+(3y)^{2}[/tex]

But, we know that [tex]-(-1)=1[/tex], so

[tex](4x)^{2}+(3y)^{2}=(4x)^{2}-(-1)(3y)^{2}[/tex]

Then,

[tex](4x)^{2}-(-1)(3y)^{2}=(4x)^{2}-(3y)^{2}i^{2}[/tex], because [tex]i^{2}=-1[/tex]

Therefore, the expression with complex numbers is

[tex](4x)^{2}-(3iy)^{2}\\\therefore (4x+3iy)(4x-3iy)[/tex]

Final answer:

The rate of the boat is 7 mph and the rate of the current is 3 mph.

Explanation:

To find the rate of the current in this problem, we can use the equation:

Rate of downstream trip = Rate of boat + Rate of current

Rate of upstream trip = Rate of boat - Rate of current

Let's assign variables to the rate of the boat and the rate of the current. Let B represent the rate of the boat and C represent the rate of the current.

From the information given, we know that:

40 miles = (B + C) x 4 hours

40 miles = (B - C) x 10 hours

Now we can solve these equations to find B and C. Let's start by simplifying the equations:

40 = 4B + 4C

40 = 10B - 10C

Divide both sides of the equations by 4 and 10 respectively:

10 = B + C

4 = B - C

Add the two equations together:

10 + 4 = 2B

14 = 2B

Divide both sides by 2:

7 = B

Substitute the value of B back into one of the equations to solve for C:

10 = 7 + C

Subtract 7 from both sides:

3 = C

Therefore, the rate of the boat is 7 mph and the rate of the current is 3 mph.

Answer:

Step-by-step explanation:

First we add 3.5% to the total.

Second we see that the total is over $125.01 thus we add another 10.95 and get 196.3185, rounded to 196.32

Answer:

Option C., $196.32 is the answer.

Step-by-step explanation:

Millicent filled out an order, worth of items = $179.10

The sales tax on that item = [tex]3\frac{1}{2}[/tex]% = 3.5%

total price of the item = 179.10 + ( 3.5% of 179.10)

179.10 + (0.035 × 179.10)

179.10 + 6.2685 = $185.3685 ≈ $185.37

Shipping and handling charges up to $125.01 and above is $10.95

Total price + shipping = 185.37 + 10.95 = $196.32

The total amount of her order is $196.32

Answer: choice C, y = 0.014x+0.85

==============================

Explanation:

Each column of the table represents an (x,y) pair of values

x = number of pages

y = cost

If we look at the first two columns, we see the two points (50,1.55) and (100,2.25). The x value is listed first. Let's compute the slope of the line through these two points

m = (y2-y1)/(x2-x1)

m = (2.25-1.55)/(100-50)

m = 0.7/50

m = 0.014

So far, we see the answer is between A,B or C as they have the slope of 0.014

Use this slope value, and one of the points -- say (x,y) = (50,1.55) -- to find the y intercept b

y = mx+b

y = 0.014x+b .... plug in the slope found earlier

1.55 = 0.014*50+b ... plug in the point (x,y) = (50,1.55)

1.55 = 0.7+b

1.55-0.7 = 0.7+b-0.7 ... subtract 0.7 from both sides

0.85 = b

b = 0.85

With m = 0.014 as the slope and b = 0.85 as the y intercept, we can say that y = mx+b turns into y = 0.014x+0.85. That narrows the answer down to choice C.

pi/3 and 2pi/3

=========================================

Work Shown:

2*sin(x) - sqrt(3) = 0

2sin(x) = sqrt(3)

sin(x) = sqrt(3)/2

Using the unit circle, we see that sin(theta) is equal to sqrt(3)/2 when theta is theta = pi/3 in quadrant I, and when theta = 2pi/3 in quadrant II.

So sin(pi/3) = sqrt(3)/2 and sin(2pi/3) = sqrt(3)/2

--------------------

You can check these answers by replacing x with the value in question and seeing if you get zero. Make sure your calculator is in radian mode

Plug in x = pi/3

2*sin(x) - sqrt(3) = 0

2*sin(pi/3) - sqrt(3) = 0

0 = 0 .................... this is a true equation, x = pi/3 is confirmed as a solution

Plug in x = 2pi/3

2*sin(x) - sqrt(3) = 0

2*sin(2pi/3) - sqrt(3) = 0

0 = 0 .................... true equation, x = 2pi/3 is confirmed as a solution

Plug in x = 4pi/3

2*sin(x) - sqrt(3) = 0

2*sin(4pi/3) - sqrt(3) = 0

-3.4641016 = 0 ............ false equation, x = 4pi/3 is a nonsolution

Plug in x = 5pi/3

2*sin(x) - sqrt(3) = 0

2*sin(5pi/3) - sqrt(3) = 0

-3.4641016 = 0 ............ false equation, x = 5pi/3 is a nonsolution

Final answer:

To solve the trigonometric equation 2 sin x - √(3) = 0 within the interval 0 ≤ x < 2π, we find that sin x = √(3)/2 at x = π/3 and 2π/3, which are the correct answer choices.

Explanation:

To solve for x in the given trigonometric equation 2 sin x - √(3) = 0, we first isolate the sine function by adding √3 to both sides and then divide by 2, giving us sin x = √(3)/2. Now, we seek the angles x within the interval 0 ≤ x < 2π (where π is pi) that satisfy this equation. We know that sin x is √(3)/2 at the angles π/3 and 2π/3 in the first and second quadrants, respectively. These are the two angles where the sine function takes the value of √(3)/2 between 0 and 2π. Therefore, the correct answer choices are π/3 and 2π/3.

It is important to consider that the sine function is positive in the first and second quadrants, and given the range for x, we don't need to consider the third or fourth quadrants where sine is negative. Additionally, the angles 4π/3 and 5π/3 correspond to a negative value of the sine function, thus they do not satisfy the equation.

Answer:

First question answer: The limit is 69

Second question answer: The limit is 5

Step-by-step explanation:

For the first limit, plug in [tex]x=8[/tex] in the expression [tex](9x-3)[/tex], that's the answer for linear equations and limits.

So we have:

[tex]9x-3\\9(8)-3\\72-3\\69[/tex]

The answer is 69

For the second limit, if we do same thing as the first, we will get division by 0. Also indeterminate form, 0 divided by 0. Thus we would think that the limit does not exist. But if we do some algebra, we can easily simplify it and thus plug in the value [tex]x=1[/tex] into the simplified expression to get the correct answer. Shown below:

[tex]\frac{x^2+8x-9}{x^2-1}\\\frac{(x+9)(x-1)}{(x-1)(x+1)}\\\frac{x+9}{x+1}[/tex]

Now putting 1 in [tex]x[/tex] gives us the limit:

[tex]\frac{x+9}{x+1}\\\frac{1+9}{1+1}=\frac{10}{2}=5[/tex]

So the answer is 5
