Answer:

The answer is 1/4

Step-by-step explanation:

1.) Take 75% and convert it to a decimal, which is 0.75

2.) Then multiply 1/3 by 0.75

3.) Your answer is 0.25, and when 0.25 is converted to a fraction it is 1/4.

The fraction of 1/3 that is equal to 75% is = 1/4

The percentage given is = 75%

The fraction given is = 1/3

To convert 75% into fraction is = 75/100

Therefore, 75/100 of 1/3

[tex] \frac{75 \times 1}{100 \times 3} [/tex]

[tex] \frac{75}{300} [/tex]

= 1/4

Therefore, the fraction of 1/3 that is equal to 75% is = 1/4.

Answer:

Function A

Step-by-step explanation:

Lets plug in the same x values used in Function A into Function B to determine the answer. Assuming -1 is the initial.

[Plug in values]

y = 3(-1) + 4 = -3 + 4 = 1

y = 3(0) + 4 = 0 + 4 = 4

By inspection, the y value when x = -1 in A is 12, which is bigger than 1 in Function B.

Answer: Function A

Step-by-step explanation:

Answer:

a. The area of the wall is 60 ft.²

b. The minimum length of wallpaper to be purchased is 30 ft

Step-by-step explanation:

a. The given diagram is a pentagon, with the two vertical sides equal in length and the  two slant sides equal in length and one horizontal

The length of the vertical sides = 6 feet each

The length of the horizontal side = 8 feet

The height of the pentagon = 9 feet

The pentagon can be split into a rectangle with a triangular cap by an horizontal line drawn at point of intersection of the vertical sides and the horizontal sides

The area of the formed rectangle = Base  × Height of rectangle

∴ The area of the formed rectangle = 6 × 8 = 48 ft.²

The area of the triangular part of the figure = 1/2 × base × Height of triangle

a = 9 - 6 = 3 feet

∴ The area of the triangular part of the figure = 1/2 × 8 × 3 = 12 ft.²

The area of the wall = The area of the formed rectangle + The area of the triangular part of the figure

∴ The area of the wall = 48 ft.² + 12 ft.² = 60 ft.²

The area of the wall = 60 ft.²

b. The width of the sold wallpaper = 2 feet wide

The area of wallpaper = Length of wallpaper × The width of the sold wallpaper

The area of wallpaper required = The area of the wall = 60 ft.²

∴ 60 ft.² = Length of wallpaper × 2 ft.

Length of wallpaper = 60 ft.²/2 ft. = 30 ft.

The minimum length of wallpaper to be purchased = 30 ft.

you can get 6 whole pieces because .54 divided by .08 equals 6.75, but you have to have whole pieces, so 6. hope you get a good grade!

Answer: (second option) (-4,1)

Step-by-step explanation:

Transformations of Points and Shapes

The image shows a trapezoid ABCD where point A has coordinates (-4,1).

The following transformations are performed:

Reflection over the y-axis: If a point (x,y) is reflected over the y-axis, it becomes (-x,y). Thus point A becomes A'=(4,1)

Reflection over the x-axis: If a point (x,y) is reflected over the x-axis, it becomes (x,-y). Thus point A' becomes A''=(4,-1)

Rotation 180°: If a point (x,y) is rotated 180°, it becomes (-x,-y). Thus point A'' becomes A'''=(-4,1)

Answer: (second option) (-4,1)

[tex]\displaystyle y=\frac{1}{2}x-7[/tex]

Step-by-step explanation:

Perpendicular Lines

Two lines of slopes m1 and m2 are perpendicular if their slopes meet the condition:

[tex]m_1\cdot m_2=-1\qquad \qquad [1][/tex]

The slope-intercept form of a line with slope m and y-intercept of b is:

[tex]y=mx+b[/tex]

The point-slope form of a line with slope m that passes through the point (h,k) is:

[tex]y-k=m(x-h)[/tex]

We are given the line

[tex]y=-2x+4[/tex]

From which we can know the value of the slope is m1=-2

The slope of the required line m2 can be calculated from [1]

[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{-2}=\frac{1}{2}[/tex]

Now we know the slope and the point (8,-3) through which our line goes, thus:

[tex]\displaystyle y-(-3)=\frac{1}{2}(x-8)[/tex]

To find the slope-intercept form, operate:

[tex]\displaystyle y+3=\frac{1}{2}x-\frac{1}{2}\cdot 8[/tex]

[tex]\displaystyle y=\frac{1}{2}x-4-3[/tex]

[tex]\mathbf{\displaystyle y=\frac{1}{2}x-7}[/tex]

Answer:

The second answer choice, 85

Step-by-step explanation:

That is a 180 degree angle, and the entire angle must add up to 180 degrees. 55+40=95, 95+85=180

We need to set up an equation where all 3 terms (x, 55°, and 40°) add up to equal 180.

Here is how we do it:

[tex]x + 55 + 40 = 180\\\\x + 95 = 180\\\\x = 85[/tex]

The answer is B: 85°.

Answer:

Because 43.3 > 40, it is possible that the picture fits in the frame.

Step-by-step explanation:

The correct explanation will be;

''Because 43.3 > 40, it is NOT possible that the picture fits in the frame.''

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

A picture frame is 24 in. wide and 36 in. high.

And, A picture with a 40 in. diagonal fit in it.

Now,

Since, A picture frame is 24 in. wide and 36 in. high.

Hence, The length of diagonal is;

⇒ d² = 24² + 36²

⇒ d² = 1,872

⇒ d = 43.26

But, Here a picture with a 40 in. diagonal fit in it.

Hence, The correct explanation will be;

''Because 43.3 > 40, it is NOT possible that the picture fits in the frame.''

Step-by-step explanation:

Answer:

v=7

Step-by-step explanation:

You want to write your equation and it should look like this:

12 - 3V+ 12Y = 4

next you wanna plug in y which in this case it is 3 now your equation should look like this:

12 - 3V+ 12(3) = 4

next you wanna multiply 12 and 3 so keep everything the same your new equation should look like this:

12 - 3V+ 36 = 4

now you wanna combine like terms and the like terms here would be 12 and 36 so you wanna subtract 12 from 36 to get you 24 and your new equation should look like this:

3V+ 24 = 4

next you want to subtract 24 from 4 and it should look like this:

3V= -20

now you want to get the variable by itself and you can do that by dividing 3 from -30 and your new equation should look like this:

v=-6.666666666666667

but you cant submit that so you wanna say v=7
