What is the most specific name for quadrilateral PQRS?

Answer:

A 18° and 72°

Step-by-step explanation:

As you know, the sum of two complementary angles = 90

The ratio 1 : 4 = 1 + 4 = 5

So 90/5 = 18

1 x 18 = 18

4 x 18 = 72

The two complementary angles are  18° and 72°

Answer

A 18° and 72°

Start with

[tex]6-\dfrac{2}{3}x<x-9[/tex]

Add 9 to both sides

[tex]15-\dfrac{2}{3}x<x[/tex]

Add [tex]\frac{2}{3}x[/tex] to both sides

[tex]15<\dfrac{5}{3}x[/tex]

Multiply both sides by 3/5

[tex]9<x[/tex]

Which is the same as

[tex]x>9[/tex]

Answer:

It's -6. She did a bunch of weird work under my answer.

Step-by-step explanation:

The x-intercept of the graph of the equation 3x + 12 = -6 can be found by solving for x. Performing the necessary operations we get x=-6, thus, the x-intercept is -6.

To find the x-intercept of the graph of the equation 3x + 12 = -6, let's first solve the equation for x. The x-intercept is the value of x where the graph intersects with the x-axis, this is the point where y = 0. By rearranging the equation, we can first subtract 12 from both sides to get 3x = -18, then divide both sides by 3 to get x = -6. So, the x-intercept of the graph is -6.

Here, we haven't needed to use information about the slope or the y-intercept, which do not affect the x-intercept. The slope of the line determines its steepness and direction, while the y-intercept determines where it crosses the y-axis. These shape the line but will not change where it crosses the x-axis.

Ok ima be your math teacher. So basically 11 squared by two equals 121. Well you may be like Why!??!?! And it is because 11 squared by two is 11X11. Lets say the question was 11 squared by 4 then the answer would be 11X11X11X11 4 times! GET IT?!

Answer:

choice c is believe is the answer

Step-by-step explanation:

Applying the Pythagorean theorem, the distance between kensington and greenwich is: b. 20√5 mi.

To solve a right triangle, where a and b are the legs and c is the longest side (hypotenuse), the Pythagorean theorem states that, c = √(a² + b²).

Apply the Pythagorean theorem to find the distance:

Distance between kensington and greenwich = √(40² + 20²)

= √(1,600 + 400)

= √2,000

= 20√5 mi.

The standard error of the proportion is

Step-by-step explanation:

Assuming that the size of population N is large enough, and with a sample [tex]n = 30[/tex], so that:

[tex]\frac{n}{N}\leq0.05[/tex] then the standard error of the proportion is:

The sum (answer) is [-1, 2, 1, 9].

Step-by-step explanation:

Here we're asked to sum up two matrices of the same dimensions (1 by 4).

The value in the first matrix, first column, is 1; that in the second matrix, first column, is -2.  Combining 1 and -2, we get -1, which is the first column value in the answer matrix.

Continuing in the same manner:  -4 + 6 = 2; 3 - 2 = 1; and 5 + 4 = 9.

The sum (answer) is [-1, 2, 1, 9].

Answer:

Y=-|x-2|

Step-by-step explanation:

To find which equation matches the graph, take 1 or 2 values of the line on the graph and enter the X and Y values of those points in the equations to see if they match

One good strategy is to take points that are along the axis. I'll first pick (1,-1) and will use (0,-2) to validate if one equation matches (1,-1) first.

Y=-|x|+2

for (1,-1) => -|1| + 2 = = -1 + 2 = 1 NO, should be -1

Y=-|x|-2

for (1,-1) => -|1| - 2 = = -1 - 2 = -3 NO, should be -1

Y=-|x+2|

for (1,-1) => -|1 + 2| = = -|1 + 2| = -3 NO, should be -1

Y=-|x-2|

for (1,-1) => -|1 - 2| = = -|-1 | = -1 YES

for (0,-2) => -|0 - 2| = = -|-2| = -2 YES

Answer:

25 minutes

Step-by-step explanation:

By using the rule of three we can solve this problem:

If a machine makes 312 bolts in 30 minutes, how much time it would take to produce 260 bolts?

312 bolts -----> 30 minutes

260 bolts ------>      X

X = (260*30)/312 = 25 minutes

312/30=10.4.

260/10.4=25

Answer:

15, 94

Step-by-step explanation:

Answer:

Given in the question an expression,

y = 3x/(8+x)

Step1

interchange the variables

x = 3y/(8+y)

Step 2

x(8+y) = 3y

Step 3

8x + xy = 3y

Step 4

8x = 3y - xy

Step 5

8x = y(3 - x)

Step 6

8x = y(3 - x)

Step 7

y = 8x/(3-x)

Step 8

y = f(x^-1) = 8x/(3-x)

So the inverse of  f(x)= 3x/(8+x) is f(x^-1) = 8x/(3-x)

Answer: 14.555

Step-by-step explanation: so you take $3.85 multiplied by 3 because they bought 3 toy cars plus a $4.56 and take the answer of that and divide by 2 because they split the cost. Hope this helps

Answer:

each girl had to pay around $8.06

Step-by-step explanation:

They bought 3 toy cars and each car was $3.85.

You have to multiply $3.85*3 which is $11.55.

Then add the $4.56 of shipping fee which is $16.11.

since the 2 girls shared the total cost, divide 16.11/2

16.11/2= $8.06

Okay so like maybe next time try to include a picture so we can see it, because we cant solve anything

Answer:

1. Area of the land which can be ploughed daily is 50 hectares (and 70 hectares at higher rate)

2. Area of the field is 700 hectares

Step-by-step explanation:

Let x hectares be the number of hectares the farmers  normally ploughed in a day. At this rate, they will complete the work in 14 days, so they have to plough

[tex]14\cdot x=14x\ hectares.[/tex]  

Then x+20 hectares is the number of hectares the farmers ploughed in a day when they increased their productivity of work. At this rate, they will complete the work in 10 days, so they have to plough

[tex]10\cdot (x+20)=10(x+20)\ hectares.[/tex]

The work is the same, so

[tex]14x=10(x+20)\\ \\14x=10x+200\\ \\14x-10x=200\\ \\4x=200\\ \\x=50[/tex]

Ploughing 50 hectares each day 14 days in a row they will plough

[tex]14\cdot 50=700\ hectares[/tex]

Answer:

[tex]ln(e^x)=ln(3)[/tex]

[tex]x=1.099[/tex]

Step-by-step explanation:

You have the following exponential expression:

[tex]2e^x=6[/tex]

You need to divide both sides of the equation by 2:

[tex]\frac{2e^x}{2}=\frac{6}{2}\\\\e^x=3[/tex]

Now apply the function Natural logarithm to both sides of the function:

[tex]ln(e^x)=ln(3)[/tex]

Note that now the exponential function is transformed into a logarithmic function.

By definition:

[tex]ln(e^x)=x[/tex] Because the base of the Natural logarithm is the Euler's number "e".

Then you can solve for "x":

[tex]x=ln(3)\\x=1.099[/tex])

Answer:

(a) Option A. independent

(b) [tex]P(A\ and\ B) = 0.0312[/tex]

Step-by-step explanation:

Two events A and B are considered dependent if the occurrence of one affects the probability of occurrence of another.

In this case, the events are independent because the birth of a girl or a boy does not affect the probability of obtaining a 1 by throwing a 16-sided die.

In the same way, throwing a die and obtaining the number 1 does not affect the probability that a baby is a girl or a boy.

When two events are independent then

[tex]P(A\ and\ B) = P(A)*P(B)[/tex]

The probability that a baby is a girl is

[tex]P(A) = 0.5[/tex]

The probability of obtaining a 1 when casting a 16-sided die is:

[tex]P(B) = \frac{1}{16}[/tex]

Then:

[tex]P(A\ and\ B) = 0.5 * \frac{1}{16}[/tex]

[tex]P(A\ and\ B) = 0.0312[/tex]

Answer:

Step-by-step explanation:

if its diameter is 30, then its radius is half that, or 15.

[tex]\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=15 \end{cases}\implies A=\pi 15^2\implies A=225\pi \implies A\approx 706.86[/tex]

Area of the circle is the area which is occupied by the circle in the two- dimensional plane. The area of the circle is equal to the area of the bottom of the circular swimming pool. Thus the blue paint is total 707.143 square feet.

The diameter of the circular swimming pool is 30 feet.

To find out the square feet of blue the area of the circle has to be calculated.

Area of the circle is the area which is occupied by the circle in the two- dimensional plane. The area of the circle with diameter [tex]d[/tex] can be calculated as,

[tex]A=\pi\times \dfrac{d^2}{4}[/tex]

Put the value of the diameter, we get,

[tex]A=\dfrac{22}{7} \times \dfrac{30^2}{4}[/tex]

[tex]A=707.143[/tex]

The area of the circle is 707.143 square feet.

As the area of the circle is equal to the area of the bottom of the circular swimming pool. Thus the blue paint is total 707.143 square feet.
