Step-by-step explanation:

420(0.882)^16 ~ 56.3 grams left

Answer: 56.3

Step-by-step explanation:

Answer:

(only ii right?)

Since we have the total number is 360° and our section is 72°, we know that the percentage of students who choose the cinema should be the number that we have divided to the total amount and then multiply the result by 100 ( it's fine if you write 100%, but when you actually calculate it, it's only 100, not 100%):

(72/360) . 100 = 20%

Width= 8 cm

Because 192 / 2 = 96 / 12 = 8

SA= (perimeter * height) + 2 (length * width)

SA= (20*12)+2(2*8)

SA= 240+32

SA= 272 cm2

Answer:

Width : [tex]8cm[/tex]

Surface Area : [tex]272cm^2[/tex]

Step-by-step explanation:

Let's consider the formula for the volume of a rectangular prism.

[tex]V=whl[/tex]

Plug the values we know into the equation.

[tex]192=w*2*12 \\ \\ 192=24w \\ \\ w=8[/tex]

So the width is 8cm.

Now let's consider the formula for the surface area of a rectangular prism.

[tex]A=2(wl+hl+hw)[/tex]

Plug in the values we know into the equation.

[tex]A=2(16+24+96) \\ \\ A=2*136 \\ \\ A=272[/tex]

So the surface area is [tex]272cm^2[/tex].

Answer:

B

Step-by-step explanation:

The question is on inverse of functions

f(x)=2x-9 -----------to find f ⁻(x)

replace f(x) with y;

f(x)=2x-9----------------y=2x-9

replace y with x and x with y

y=2x-9------------------x=2y-9

solve for y

x=2y-9

x+9=2y

(x+9)/2 =y

replace y with g(x) or f ⁻(x)

g(x)=x+9 /2

Answer:

2x+3y-5=0

Step-by-step explanation:

We have been given two points  (4,-1) and (-2,3). Now we need to find about

what is the equation of the line that passes through (4,-1) and (-2,3).

Slope of the line through the points  (4,-1) and (-2,3)  is given by:

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

[tex]m=\frac{3-\left(-1\right)}{-2-4}=\frac{3+1}{-6}=\frac{4}{-6}=-\frac{2}{3}[/tex]

Now plug the slope [tex]m=-\frac{2}{3}[/tex] and point (4,-1) into point slope formula

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y--1=-\frac{2}{3}\left(x-4\right)[/tex]

[tex]y=-\frac{2}{3}x+\frac{5}{3}[/tex]

or we can rewrite that as 2x+3y-5=0

Hence final answer is 2x+3y-5=0

The answer is:

The second option

[tex]2x+3y-5=0[/tex]

To know which is the equation of the line, we need to follow the next steps:

Find the slope of the line:

We are given the points:

[tex](-2,3)\\(4,1)[/tex]

Where,

[tex]x_1=4\\y_1=-1\\x_2=-2\\y_2=3[/tex]

Also, we know that we can calculate the slope of a function using the following formula:

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

Now, using the slope formula, and substituting the given points, we have:

[tex]m=\frac{3-(-1)}{-2-4}[/tex]

[tex]m=\frac{4}{-6}[/tex]

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

Find the "b" value:

In order to find "b" we need to substitute any of the given points, we know that line pass through both of the given points, so, substituting the point (4,-1), we have:

Writing the slope form of the function,

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

[tex]y=-\frac{2}{3}x+b[/tex]

[tex]-1=-\frac{2}{3}*(4)+b\\\\b=-1+\frac{2}{3}*(4)=-1+\frac{8}{3}=\frac{-3+8}{3}=\frac{5}{3}[/tex]

Now that we know the slope and "b", we can write the equation of the line in slope-intercept form:

Writing the equation of the equation, we have:

[tex]y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Then, by multiplying each side of the equation by 3 in order to simplify the fractions, we have:

[tex]3y=(3)*(-\frac{2}{3}x)+(3)*(\frac{5}{3})[/tex]

[tex]3y=-2x+5[/tex]

Rewriting the equation, we have:

[tex]2x+3y-5=0[/tex]

Hence, we have that the correct option is the second option, the equation of the line that passes through the given points is:

[tex]2x+3y-5=0[/tex]

Have a nice day!

Answer:

The answer to this is 11.666.....

Step-by-step explanation:

To find mean we add up all value and in this case we add all of which resulting into 105 and to find out average we must divide by the amount of terms (this case numbers)

105/9 gives us an answer of 11.666...

Hope this helps and enlightens your day

To find the mean, you add up all of the numbers, then divide the sum by the amount of numbers you have.

You have 9 numbers:

22, 7, 22, 1, 7, 18, 16, 6, 6

Now you need to add them together

22 + 7 + 22 + 1 + 7 + 18 + 16 + 6 + 6 = 105

Now you divide:

[tex]mean=\frac{105}{9}=\frac{35}{3}[/tex] or 11.6666666666.......

Answer:

Step-by-step explanation:

Here we are going to use the rule which says that

i) equal arc segments subtends equal angles at the circle

ii) The Angle subtended by any arc segment at center is double to that of the angle subtended by the same arc at its circumference.

For more details please refer to the image attached to this problem.

Let us say that the angle subtended by arc mAB at center O = 6∅

Hence , ∠AOB=6∅

Hence ∠ADB = 3∅ ( Rule ii as discussed above )

Also as length of arc mCD = x , the angle subtended by it on the center will be in the same ratio as it was subtended by arc with length 6x

Hence

∠COD=∅

Hence

∠CAD=∅/2

Hence in ΔATD

∠ATD + ∠ADT +∠DAT = 180°

∠ATD + 3∅+∅/2= 180°

∠ATD = 180° - (3∅+∅/2)    ----------(A)

Also

∠ATD + ∠ATB = 180°

From (A)

180° - (3∅+∅/2) +∠ATB =  180°

∠ATB = (3∅+∅/2)

∠ATB = (6∅+∅)/2

∠ATB = (7∅)/2

However , in order to find the exact value of∠ATB  we need to evaluate  ∅, and to find it , we must have some value of x .

Answer:

Slope: 7

y-intercept:-6

Step-by-step explanation:

The equation of the line in Slope-intercept form is the following:

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

Where "m" is the slope of the line and "b" is the y-intercept.

You have the equation of the given line:

[tex]y=7x-6[/tex]

You can observe that it is written in Slope-intercept form, therefore, you can identify that the slope and the y-intercept are the following:

[tex]m=7\\b=-6[/tex]

A. The slope is 7.

B. The line rises steeply right 7 units for every 1 unit increase in x.

Here's how to find the slope and y-intercept directly from the equation:

Understanding the Slope-Intercept Form:

The equation of a line can be written in *slope-intercept form* as `y = mx + b`, where:

`m` represents the slope of the line.

`b` represents the y-intercept, which is the point where the line crosses the y-axis.

Identifying Slope and Y-Intercept:

In the given equation, `y = 7x - 6`, we can directly identify the values:

The slope `m` is the coefficient of `x`, which is 7.

The y-intercept `b` is the constant term, which is -6.

Interpreting the Slope:

A slope of 7 indicates that for every 1 unit increase in `x`, the `y` value increases by 7 units. This means the line rises steeply from left to right.

Question:

Find the slope and y-intercept of the line whose equation is y= 7x-6.

What is the slope? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A. The slope is ______ (Type an integer or a fraction.)

B. The slope is undefined.

Answer:

x=7

Step-by-step explanation:

We know that When we total the angles in the same arm od trapezoid wee will obtain 180°.

Hence :

12x+3+13x+2=180

25x+5=180

5x+1=36

5x=35

x=7

Greetings From Poland :)

Answer:

the answer is D:  median

Step-by-step explanation:

Median and mean are measures of center.

Mean is best to use when the data distribution is symmetric or mostly symmetric, whereas median is best to use when the data distribution is not symmetric, or skewed.

Since the data distribution is skewed and not symmetric, the median is the best measure of center for the data.

ANSWER

[tex]1 \frac{11}{16} ounces[/tex]

EXPLANATION

It was given that,a bottle of la belle bœuf contains 3/8 ounces of perfume.

We want to find how many ounces of perfume would 4 1/2 bottles contain.

If 1 bottle contains 3/8 ounces;

Then 4½ bottles should contain more ounces.

If more less divides.

4½ bottles contain

[tex] \frac{4 \frac{1}{2} \times \frac{3}{8} }{1} [/tex]

[tex] = \frac{27}{16} [/tex]

=1.6875 ounces.

4 (1/2) bottles of  la belle bœuf contains 1 (11/16) ounces of perfume.

To find out how many ounces of perfume are in 4(1/2) bottles of La Belle Bœuf, we need to multiply the amount of perfume in one bottle by the number of bottles.

First, let's convert 4(1/2) bottles into an improper fraction:

Next, multiply by the amount in one bottle:

Therefore, 4(1/2) bottles of La Belle Bœuf contain 1 (11/16) ounces of perfume.

-25x ≥ 100 → -25(4) ≥ 100 → -100  ≥ 100 FALSE

25x < 100 → 25(4) < 100 → 100 < 100 FALSE

25x ≤ 100 → 25(4) ≤ 100 → 100 ≤ 100 TRUE

Answer:

x=200

Step-by-step explanation:

x−y=80

3/5 = y/x

Multiply the second equation by x

3/5 x = y/x *x

3/5 x = y

Substitute this into the first equation for y

x-y =80

x - 3/5x = 80

2/5 x = 80

Multiply each side by 5/2 to isolate x

5/2 *2/5x = 80 *5/2

x = 200

3) The equation of the line in standard form is equal to [tex]4x-3y=-3[/tex]

Step-by-step explanation:

we have that the line passes through the points

(9,11) and (21,27)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

substitute the values

[tex]m=\frac{27-11}{21-9}[/tex]

[tex]m=\frac{16}{12}[/tex]

[tex]m=\frac{4}{3}[/tex]

step 2

Find the equation of the line into point slope form

The equation of the line is

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{4}{3}[/tex]

[tex]point (9,11)[/tex]

substitute

[tex]y-11=\frac{4}{3}(x-9)[/tex] -----> equation of the line into point slope form

step 3

Find the equation of the line in slope intercept form

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

[tex]y-11=\frac{4}{3}(x-9)[/tex]

[tex]y=\frac{4}{3}x-12+11[/tex]

[tex]y=\frac{4}{3}x-1[/tex] -----> equation of the line in slope intercept form

Answer:

Andy = 84 and Bart = 105

Step-by-step explanation:

Given that the ratio is 4 : 5 = 4x : 5x

Andy loses 9 thus 4x - 9

ratio 4x - 9 : 5x = 5 : 7, that is

[tex]\frac{4x-9}{5x}[/tex] = [tex]\frac{5}{7}[/tex] ( cross- multiply )

25x = 7(4x - 9) ← distribute

25x = 28x - 63 ( subtract 28x from both sides )

- 3x = - 63 ( divide both sides by 3 )

x = 21

Hence

Andy = 4x = 4 × 21 = 84 marbles

Bart = 5x = 5 × 21 = 105 marbles

Answer:

1). This is a right angle triangle = TRUE

2). The hypotenuse of the triangle has a length of 21 = FALSE ("C" is the hypotenuse which makes 21 and 20 the leg of the triangle)

3). One of the legs has a length of 20 = TRUE

4). The length of "c" can be found by 202 + c2 = 212 = FALSE (To calculate the hypotenuse of the triangle you should use the formula a² + b² = c² )

"A" and "C" are the correct answers <3

Answer:

y = 23

Step-by-step explanation:

Since it's a rhombus, we know that the two diagonals are perpendicular.

That means that angle 1 is necessary a right angle, so it's worth 90 degrees since it's at the meeting point of the two perpendicular diagonals.

So, we have

∠1 = 4y - 2

All we have to do is to replace ∠1 by its value (90) and solve the mini-equation:

90 = 4y - 2

92 = 4y

y = 23

Step-by-step explanation:

I assume that the figure is a square

The area of a square is equal to

[tex]A=b^{2}[/tex]

where

b is the length side of the square

In this problem we have

[tex]b=2(\sqrt{7})=2\sqrt{7}\ m[/tex]

substitute in the formula

[tex]A=(2\sqrt{7})^{2}[/tex]

[tex]A=28\ m^{2}[/tex]

Answer:

The correct answer option is B. 21.

Step-by-step explanation:

We are given a figure where the line KL is intersecting another line MN such that angle from K to N is equal to the angle opposing it which is the angle measuring [tex](5x)[/tex].

Measure of angle K - N = 90° + 15° = 105°

Since angle K - N = angle M - L, we can write it as:

105° = 5x

x = 105/5

x = 21

Therefore, the correct answer option is B. 21.

Answer:

The correct answer is option B

21

Step-by-step explanation:

From the figure we can see a number of line segments

To find the value of x

Let the point of intersection of line segments be 'o'

From the figure we get, <KON and <MOL are vertically opposite angles

m<KON = m<MOL

90 + 15  = 5x

5x = 105

x = 105/5 = 21

Therefore the value of x = 21

You would do 180 - 115 and that gives you the < for 7

Answer:

1. 65 deg

2. 115 deg

3. 115 deg

Step-by-step explanation:

1.

Angles 7 and 8 are supplementary. Their measures add to 180 deg.

m<7 + m<8 = 180

m<7 + 115 = 180

m<7 = 180 - 115

m<7 = 65

2.

Since lines p and q are parallel lines cut by a transversal, corresponding angles 6 and 8 are congruent.

m<6 = m<8

m<6 = 115

3.

Angles 1 and 6 are vertical angles, so they are congruent.

m<1 = m<6

m<1 = 115
