How much do you need to subtract from 53/6 to make 8

Answer:

-9.5

Step-by-step explanation:

To solve for z, use inverse operations by multiplying both sides by 2.

-4.75 = z/2

-9.5 = z

To solve the equation -4.75 = z/2, multiply both sides by 2 to isolate z, which gives you the solution z = -9.5.

To solve for z in the equation -4.75 = z/2, you need to isolate z on one side of the equation. This can be achieved by multiplying both sides of the equation by 2 (the reciprocal of 1/2, which is the current coefficient of z) to cancel out the division.

Here's the calculation step by step:

Therefore, the solution to the equation is z = -9.5.

Answer: 215 seconds

Step-by-step explanation:

This is a ratio problem so you can set up the ratio like this:

120 words : 100 second.

If you divide both sides of the ratio by 120 you get:

1 word: 0.8333 seconds

Multiply both sides of the ratio by 258 and you get:

258 words: 215 seconds.

Therefore typing 258 will take them 215 seconds.

This will take 215  seconds  to type 258 words.

This problem is solved by the concept of unitary method.

Given that  Typist types 120 words in 100 seconds

so in one second he types 120/100 words = 1.2 Words per second

let us suppose he types  258 words in 'x' seconds  

so in one second he types 258/x words

258/x = 1.2  

x = 258/1.2  

x = 215 seconds

First, you need to find out the are of the whole rectangle, which as you probably know, you just need to multiply base by height.

Then, you need to substract the are of the two little squares, which luckily are both the same size. To find out the are of a square you multiply a side twice.

Therefore,

Whole rectangle area:

(32+8) * (8+8) = 40 * 16 = 640 sq. ft.

Two small squares:

2 * (8 * 8) = 2 * 64 = 128 sq. ft.

We substract:

640 - 128 = 512 sq. ft.

Answer:

512

Step-by-step explanation:

i fond the area of the whole big rectangle , so to do this i did 32+8 because i needed to find length. then i found the width, which was 8+8, 16. to find area , i need to multiply with times height so i did 40 x 16. this gets me to 640, but now i need to take out the two smaller cubes since i included them when i found the are of the rectangle. since the sides of both squares are 8 by 8, we can do 8 x 8 x 2 to find the area of both of them. now we taake 128(the product of 8 x 8 x 2) and subtract it from the big rectangle with the area of 640. 640-128 is 512.

Answer:

1. add up all of the arcs.

2x+3x+4x-8+x-12

2. all of the arcs equal 360

2x+3x+4x-8+x-12=360

3. Find x

10x-20=360, x=38

4. angle LTE is equal to half of the sum of the intercepted arcs.

.5(arc LE +GF)

5. plug in LE +GF with x

.5(76+144)

LTE=110

Applying the angles of intersecting chords theorem, m∠LTE = 110°.

When two chords intersect inside a circle, according to the angles of intersecting chords theorem, the vertical angle formed equals the half the sum of the measures of the intercepted arcs.

Given the following:

A full circle = 360°

Therefore we would have:

2x + 3x + 4x - 8 + x - 12 = 360

Add like terms

10x - 20 = 360

10x = 360 + 20

10x = 380

x = 38

Based on the angles of intersecting chords theorem, we have:

m∠LTE = 1/2(EL + GF)

Substitute

m∠LTE = 1/2(2x + 4x - 8)

m∠LTE = 1/2(6x - 8)

Plug in the value of x

m∠LTE = 1/2(6(38) - 8)

m∠LTE = 1/2(220)

m∠LTE = 110°

Answer:

See the attached image

Step-by-step explanation:

You must graph the system of equations. To do so, find the intersection points of each line with the axes.

2x-y=4   intersection with the x axis. -----y=0

2x = 4

x = 2.

2x-y=4   intersection with the y axis. -----x=0

-y = 4

y = -4.

Now we have

3y-3x=6     intersection with the x axis. -----y=0

-3x = 6

x = -2

3y-3x=6     intersection with the y axis. -----x=0

3y = 6

y = 2.

Now you can graph both lines. The solution the system will be the intersection of both lines

Answer:

[tex]B=12x[/tex]

Step-by-step explanation:

Given: [tex]cos^2(6x)-sin^2(6x)=cos(B)[/tex]

Let's simplify the left part of the equation:

[tex]cos(12x)=cos(B)[/tex]

Solve for B:

[tex]B=12x[/tex]

Final answer:

To find the value of B for the given equation, we employ the cosine double angle identity, which leads us to determine that B equals 12x or 12x ± 2kπ, considering the periodic nature of the cosine function.

Explanation:

The question asks us to find the value of B given that cos2(6x) - sin2(6x) = cos(B). This expression can be rewritten using a trigonometric identity, the cosine difference identity, which states that cos(A) - cos(B) = -2sin((A+B)/2)sin((A-B)/2). However, in our case, we use the cosine double angle identity, which states that cos(2θ) = cos2(θ) - sin2(θ). Applying this identity to the given expression gives us cos(12x) = cos(B). Therefore, B = 12x or B = 12x ± 2kπ, where k is an integer, because the cosine function is periodic with a period of 2π.

Answer:

(3,1)

Step-by-step explanation:

Calculate the rise-over-run ratio to find the slope between the points.

r/r between 0,5 and 2,2 was -3/2

r/r between 2,2 and 4,-1 was -3/2

r/r between 0,5 and 4,-1 was -6/4 = -3/2

r/r between 0,5 and 3,1 was -4/3

r/r between 2,2 and 3,1 was -1/1

as you can see the r/r for the points involving 3,1 was inconsistent with the rest, therefore it is not part of the linear system.

The point that the graph does not pass through is (3 ,1)

An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.  

An equation in which the slope is constant is called a linear equation.

Slope of the graph between points (0, 5), (2, 2) =   [tex]\frac{2-5}{2-0} = -\frac{3}{2}[/tex]

Slope of the graph between points (2, 2) , (4, -1) = [tex]\frac{-1-2}{4-2} = - \frac{3}{2}[/tex]

Slope of the graph between points (0, 5), (4, -1) =  [tex]\frac{-1-5}{4-0} = -\frac{-6}{4} = - \frac{3}{2}[/tex]

Slope of the graph between points (3, 1) , (0, 5) = [tex]\frac{5-1}{0-3} = - \frac{4}{3}[/tex]

Slope of the graph between points  (3, 1) ,  (2, 2) = - 1

Slope of the graph between points  (3, 1) , (4, -1) = -2

So, we can say the graph is not passing through the point (3 , 1).

Answer:

x² + 50x + 600

Step-by-step explanation:

The length changes from 20 yards to 20 + x. The width changes from 30 to 30+x.

The area will be A = l*w = (20+x)(30+x).

Use the distributive property to find the polynomial simplified.

A = (20+x)(30+x) = 600 + 30x + 20x + x² = 600 + 50x + x²

Write the polynomial in descending order by writing the exponents first.

x² + 50x + 600

The polynomial representing the area of the new parking lot would be 600 + 50x + x^2 square yards, where x is the amount by which both the length and width are increased.

The area of the initial parking lot can be computed using the formula for the area of a rectangle, which is length times width. In this case, the area would be 20 yards times 30 yards, or 600 square yards.

If we let x be the amount by which both the length and the width are increased, the new length becomes 30 + x yards, and the new width becomes 20 + x yards.

Therefore, the polynomial representing the area of the new parking lot would be (30+x)(20+x), which equals 600 + 50x + x^2 square yards.

The scale factor of triangle ABC to triangle DEF is 1/6.

Compare corresponding side lengths:

I observed that a side length of triangle ABC (2 units) is 6 times smaller than the corresponding side length of triangle DEF (12 units).

This initial comparison hinted at a scale factor of 1/6.

Checked other side lengths:

To confirm, I verified that the other side lengths also have a ratio of 1/6.

AB = 2 units, DE = 12 units (2/12 = 1/6)

AC = 4 units, DF = 24 units (4/24 = 1/6)

BC = 2 units, EF = 12 units (2/12 = 1/6)

Since all corresponding side lengths have a ratio of 1/6, this confirms that triangle ABC is a scaled-down version of triangle DEF with a scale factor of 1/6.
