On a trip to the grocery store, Zach purchased 7 pounds of fruits and vegetables. How many
kilograms is 7 pounds? Round your answer to the nearest hundredth of a kilogram.

Answer:

See Below.

Step-by-step explanation:

We are given the equation:

[tex]a=2x+6xz[/tex]

And we want to solve for x.

On the right-hand side, we can factor:

[tex]a=x(2+6z)[/tex]

And divide both sides by the factored expression. Hence:

[tex]\displaystyle x=\frac{a}{6z + 2}[/tex]

And we're done!

Answer:

x=a/2(1+3z)

Step-by-step explanation:

The easiest way to visualize this problem is to sketch a quick diagram.

For this problem, you are given an angle and the length of the side of a triangle. If you look at the diagram, you'll see that the length given is the opposite side of the angle given. For this situation, that means you will use the sine function (refer to SOH-CAH-TOA acronym). Then you plug in the given values and solve for x.

Answer 7

Step-by-step explanation

do theis prdcjkfbiubnvckdnsgjibjkdsvhbrhvbbghbvhvbhbgfndjsnjdnsndj

Step-by-step explanation:

Area of triangle = 1/2 × the width × the length

42 = 1/2(x+3)(2x+8)

42 = 1/2×2×(x+3)(x+4)

42 = (x+3)(x+4)

(x+3)(x+4) = 42

x² + 7x + 12 = 42

x² + 7x + 12 - 42 = 0

x² + 7x - 30 = 0

(x-3)(x+10) = 0

x = 3, -10

x can't be -10 because the width and the length should be only + values

x = 3

The value of x found by using the area of triangle concept is 3

What is the Area of a Triangle?
The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area. The fundamental equation for a triangle's area is A = 1/2 b × h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, may be calculated using this formula. It is important to keep in mind that a triangle's base and height are perpendicular to one another.

In the question, It is given that:

Area of triangle = 42.

Width of the triangle = x+3

Length of the triangle = 2x+8;

And, we know that:

Area of triangle = [tex]\frac{1}{2}[/tex]×[tex]lw[/tex]

⇒[tex]42[/tex] = [tex]\frac{1}{2}[/tex]×[tex](x+3)(2x+8)[/tex]

⇒42 = (x+3)(x+4)

⇒(x+3)(x+4) = 42

⇒x² + 7x + 12 = 42

⇒x² + 7x + 12 - 42 = 0

⇒x² + 7x - 30 = 0

⇒(x-3)(x+10) = 0

⇒x = 3, -10

x can't be -10 because the width and the length should be only + values

⇒x = 3

Hence, The value of x is 3.

Answer: 144

Step by step: In order to solve this easily, you should convert 3/5 into a decimal. In order to do that, you have to divide the numerator by the denominator. 3 divided by 5 = 0.6. Then you multiply 240 by 0.6 to get your answer, 144.

Hey There!! ~

The answer to this is: the upper bound for the length is [tex]21.5cm.[/tex] Lower and Upper Bounds

The lower bound is the smallest value that will round up to the approximate value.

The upper bound is the smallest value that will round up to the next approximate value.

Ex:- a mass of 70 kg, rounded to the nearest 10 kg, The upper bound is 75 kg, because 75 kg is the smallest mass that would round up to 80kg.

Here , A length is measured as 21cm correct to 2 significant figures. We need to find what is the upper bound for the length . let's find out:

As discussed above , upper bound for any number will be the smallest value in decimals which will round up to next integer value . So , for 21 :

⇒  [tex]21.5cm.[/tex]

21.5 cm on rounding off will give 22 cm . So , the upper bound for the length is [tex]21.5cm.[/tex]

the answer is 1/6.......

Answer:

  86°

Step-by-step explanation:

If you draw a line segment AC, it forms the rest of right triangle ACB with the right angle at C. Then angle BAC is the complement of the given angle:

  ∠BAC = 90° -47° = 43°

The inscribed angle BAC intercepts arc BC, so the arc measure will be double the angle measure.

  arc BC = 2·43° = 86°

__

Another way to get there is to realize that arc BCA is 180°, because AB is a diameter. As above, arc AC will be double the measure of inscribed angle ABC, so arc AC has measure 94°.

  arc BC = arc ACB - arc AC

  arc BC = 180° -94°

  arc BC = 86°

Answer:N/B The amount is in thousands

The total amount earned by a Bachelor's person be $x:

amount earned by a masters person will be $(2x-38)

Total amount earned by the two individuals will be:

x+(2x-38)=115

solving for x we get:

x+2x-38=115

3x=115+38

3x=153

x=153/3

x=51

also:

2x-38=2*51-38=64

therefore we conclude that master's individual earns average of $ 64,000 while the Bachelor's individual earns $51,000.

Answer: 5 feet

Step-by-step explanation: To find the width of the rectangle,

start with the formula for the perimeter, shown below.

Perimeter = 2l + 2w

Since we know the perimeter is 36 and the

length is 13, we have 36 = 2(13) + 2w.

Simplifying on the right, we have 36 = 26 + 2w.

Not subtract 26 from both sides to get 10 = 2w.

Now divide both sides by 2 and 5 = w.

So the with is 5 feet.

Answer:

19

Step-by-step explanation:

So we have the function:

[tex]f(x)=40+4x+x^2[/tex]

And we want to find the slope of the chord that connects the points (5,f(5)) and (5+Δx, f(5+Δx)).

So first, find the two points.

1) (5,f(5))

Substitute in 5 for x:

[tex]f(x)=40+4x+x^2\\f(5)=40+4(5)+(5)^2[/tex]

Square and multiply:

[tex]f(5)=40+20+25[/tex]

Add:

[tex]f(5)=85[/tex]

So, our first point is (5,85)

2) (5+Δx, f(5+Δx))

Remove the Δx by substituting it with 5. Thus:

[tex](5+\Delta x,f(5+\Delta x))=(5+5,f(5+5))=(10,f(10))[/tex]

Now, substitute in 10 for x. Thus:

[tex]f(10)=40+4(10)+(10)^2[/tex]

Square and multiply:

[tex]f(10)=40+40+100[/tex]

Add:

[tex]f(10)=180[/tex]

So our second point is (10,180).

Now, just find the slope between (5,85) and (10,180) using the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (5,85) be x₁ and y₁ and let (10,180) be x₂ and y₂. Substitute:

[tex]m=\frac{180-85}{10-5}[/tex]

Subtract:

[tex]m=\frac{95}{5}[/tex]

Divide:

[tex]m=19[/tex]

So, the slope that connects the chord is 19.

And we are done :)

Answer:

x= -30.5

Step-by-step explanation:

In order to solve equations like this, we need to have all the x terms on one side, and all the other terms on the other side. For this equation so far, the x term (2x) is not alone (there is a +2) so we need to move the +2 to the other side to have x by itself. Whatever you do to one side of equation, you must also do to the other side to keep the equation equal. Therefore we can subtract 2 from both sides which moves the two to the other side while keeping the equation equal. In order to move a term to the other side, we must do the operation opposite to what the term has. E.g. +2 is adding 2, so to move it to the other side, we need to subtract 2.

2x +2 -2 = -59 -2

Which cancels out the 2 on the left side and gives us:

2x = -59-2

2x = -61

Then we just need to remove the 2.

In this case, this 2 is being multiplied to the x, so to move it, we will need to divide both sides by 2.

2x/2 = -61/2

which finally gives us:

x = -30.5

Answer:

Step-by-step explanation:

Given the expression u= av + bw where u = 2i + j, v = i + j, and w = i - j, to find the scalars a and b, we will first substitute the vectors into the expression given as shown;

u= av + bw

2i + j = a( i + j)+b(i-j)

open the parenthesis

2i + j = ai+aj+bi-bj

collect like terms at the right hand side of the equation

2i + j = ai+bi+aj-bj

2i + j = (a+b)i+(a-b)j

compare the coefficient of complex value i and j on both sides

a+b = 2 ............... 1

a-b = 1................. 2

solve the resulting equation simultaneously using elimination method

Subtract both equation from each other.

(a-a) +(b-(-b))= 2-1

0+2b = 1

b = 1/2

Substitue b = 1/2 into equation 2 to get a

From equation 2, a = 1+b

a = 1 + 1/2

b = 3/2

Hence the scalars a and b are 1/2 and 3/2 respectively

[tex]a=\frac{3}{2},b=\frac{1}{2}[/tex]

A complex number is of the form [tex]\boldsymbol{a+ib}[/tex] where [tex]a,b[/tex] are real numbers.

[tex]u=2i+j[/tex]

[tex]v=i+j[/tex]

[tex]w=i-j[/tex]

[tex]u=av+bw[/tex]

So,

[tex]2i+j=a(i+j)+b(i-j)[/tex]

[tex]2i+j=(a+b)i+(a-b)j[/tex]

Therefore,

[tex]2=a+b\\1=a-b[/tex]

Add these equations.

[tex]3=2a\\\frac{3}{2}=a[/tex]

So,

[tex]1=\frac{3}{2}-b\\\\b=\frac{3}{2}-1\\[/tex]

  [tex]=\frac{1}{2}[/tex]
