PLEASE HELP WHAT IS THIS PKLEASE :


x/12 = -2

Answer:

9 :  7, or 9/16 to 7/16

Step-by-step explanation:

We know that there are 9 blue hats.

We know there are 7 red hats.

This is a 9 : 7 ratio.

In fraction form, we must find the total ratio, use that as the denominator, then take the seperate amounts, such as bluei adn red hats, and use that as the numerator:

9+7=denominator

denominator = 16

Blue hats = 9

Ratio of red = 9/16

Red hats = 7

Ratio of red = 7/16

Hope this helps!

Answer:

The steps as for drawing a random sample as stated in Sampling Theory textbook by Shalabh, IIT Kanpur are;

1) Specify the population from which the sample is to be drawn by numbering each unit

2) From the random number table, arbitrarily select a number and read the selected number

3) From the population the unit that has the corresponding serial number with the selected random number

4) If a selected random number is repeated, ignore the number when performing Simple Random Sampling Without Replacement SRSWOR

5) Continue the process until the 20 units in the sample are selected

Answer:

10 quarters

40 dimes

Step-by-step explanation:

q + d = 40

25q + 10d = 625

25 > 10

q < d

25(10) = 250

10(40) = 400

$2.50 + $4.00 = $6.00

Answer:

9

Step-by-step explanation:

Because all other answers round down

Answer:

The missing digit is 9

Step-by-step explanation:

For this question, we would look at rounding rules. Given that the first 3 numbers after the decimal are 383, if we want the secon 3 to round up to a 4, then the 4th number after the decimal would have to be greater than or equal to 5. The only option that matches this is 9. Hope this helps!

Answer:

y=-4x+4

Step-by-step explanation:

y-y1=m(x-x1)

y-(-4)=-4(x-2)

y+4=-4(x-2)

y=-4x+8-4

y=-4x+4

A slope of a line is the change in y coordinate with respect to the change in x coordinate. The equation of the line in slope intercept form which is passing through (2,-4) is  -4x +7.

A slope of a line is the change in y coordinate with respect to the change in x coordinate. The equation of a line in slope intercept form is given by

y = mx + c.

Given the slope of the line, m=-4. Also, the point through which the line is passing,

(x₁ ,y₁) =(2,-4)

Since the equation of the line in the slope-intercept form of the line is given by

y = mx +c

Since, the above line is passing through (2, -4) and the slope is -4.

Therefore,-4 = -4(2) + c⇒ -4 = -8 + c⇒ -1 +8 = c⇒ c = 7

Substitute the value of m and c in the equation

y = mx + c

⇒ y = mx + c

⇒ y = -4x +7

Therefore, the equation of line in slope intercept form which is passing through (2, -4) is y = -4x +7.

Answer:

Option (2)

Step-by-step explanation:

1). Equation of the line given in the question is,

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

Slope of the line = [tex]\frac{1}{2}[/tex]

Slope of the line given in the graph = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

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

But [tex]\frac{1}{2}\neq \frac{3}{4}[/tex]

Therefore, slopes of the line and the line given in the graph are not equal.

Option (1) is incorrect

2). Since, [tex]\frac{3}{4}> \frac{1}{2}[/tex]

Therefore, Option (2) is correct.

3). Since, graph has a greater slope, option (3) is incorrect.

Option (2) is the correct statement.

Explanation:

HA = hypotenuse angle

The tickmarks tell us that the hypotenuse IJ is the same length as the hypotenuse LM. So that's the "hypotenuse" portion of "HA".

The "angle" portion refers to the acute angles HIJ and KLM being the same measure, as shown by the curved arc marking. We aren't referring to the right angles because the HA theorem can only be used for right triangles, so that means the right angle is already built into it (and we can ignore the right angles).

Notice how HA is a special case of AAS.

Answer:

the answer is A

Step-by-step explanation:

Answer:

1 = 117 ( vertically opposite angles are equal )

2 = 117 ( corresponding angles are always equal )

Step-by-step explanation:

Answer:

angle one=122 because it is using the alternate interior angle theorem

angle 2=58 because it is using the consecutive interior angle theorem

hope this helps

have a good day :)

Step-by-step explanation:

remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58

since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle

Answer:

I'll setup the problem, you do the calculation

Step-by-step explanation:

given the area of a square, you take the square and that is the side of the square

[tex] \sqrt{9 {q}^{4} {r}^{8} {s}^{6} } [/tex]

the square root of a number that is raised to a power is found by dividing the power by 2

example

[tex] \sqrt{ {x}^{6} } = {x}^{3} [/tex]

do that for each term and you have you answer

Answer:

x = 22

Step-by-step explanation:

line AD is 180°

so 40° + (5x + 30°) = 180°

solve for x.

5x = 180-30-40

5x= 110

x = 110/5

x= 22

Answer: 22

180 - 40 = 140

5(22) = 110

110 + 30 = 140

Answer:

The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04

Step-by-step explanation:

Answer:

Volume - 452.16 cm

Step-by-step explanation:

First we need to find the area of the circle.

Area of a circle - (3.14)r^2

Insert the radius in the formula -

(3.14) (4)^2

3.14 x 16

50.24 is the area of the circle

Now, we have to multiply this value by the height of the cylinder in order to find the volume.

50.24 x 9 = 452.16 cm

Answer:

2(2x + y + 3y)

=

4x + 8y

4x + 2y + 6y

Answer:

96×pi ft³

Step-by-step explanation:

by the way, it is totally easy to search for formulas on the internet.

the volume of a cone is

Vc = pi×r²×height/3

we have been given the slant height (10 ft) and the lateral "wall" area of the cone (60×pi ft²).

this wall area is

Aw = pi×r×slant height

60×pi = pi×r×10

60 = r×10

6 = r

so, now we know r fuer the volume formula, and we need the height of the cone (the inner one).

we use Pythagoras

10² = r² + height²

100 = 36 + height²

height² = 64

height = 8 ft

so, now we use the main formula for the volume

Vc = pi×r²×height/3 = pi×6²×8/3 = pi×36×8/3 = pi×12×8 =

= 96×pi ft³

cubic feet ! it is a volume !
