Step-by-step explanation:

cuz it's the number below

Answer:

131 is prime. So the answer is A

Step-by-step explanation:

Remark

x is one of the legs. The other one is √65

Equation

x^2 + (√65)^2 = 14^2

Solution

x^2 + 65 = 196                 Subtract 65 from both sides

x^2 = 196 - 65

x^2 = 131                          Take the square root of both sides.

√x^2 = √131

x = √131                    

Answer:

the output is 3

Step-by-step explanation:

look for the point on the graph whose coordinate is -1

the point on the graph whose x coordinate is -1 is (-1,3)

so its 3

Answer:

1/3

Step-by-step explanation:

Y/x=k that is the equation for constant of proportionality

2/6=k

1/3=k

Answer:

Step-by-step explanation:

We observe that the difference of terms is 4, 7 and 15 and next level difference is 4. It means the sequence is quadratic.

We can compare this with simple quadratic sequence

and find out that doubling each term gives us

This is close to our sequence, write the terms as follows to find exact rule

The first term:

The second term

The third term:

The fourth term:

The nth term as per observation above is:

Answer:

D 30

Step-by-step explanation:

each angle in the hexagon=120°

angleSMN=120°

all triangles =180° in total

180-120= 60

60÷2 =30

remaining 2 angles = 30° each

Answer:

3* 2*3*2 is n

Step-by-step explanation: well find a way to put 3 and 2 two times in expressions and expressions have no equal signs steer clear of that.

Answer:

C

Step-by-step explanation:

Because lets say we have a point (1,2)

when reflecting this point over the y-axis it becomes (-1,2) so only the sign of the X value changes. Therefore by writing the system f(x)=g(-x) it changes the X value.

Answer:2=B , -3=T. 5=S. 40=L

Step-by-step explanation:

Answer:

The points are 1 unit apart.

Step-by-step explanation:

Given points are:

(3.1,-1) and (4.1,-1)

Distance formula is given by;

Distance between points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where,

[tex](x_1,y_1)[/tex] = Coordinates of first point

[tex](x_2,y_2)[/tex] = Coordinates of the second point

Putting the values,

Distance = [tex]\sqrt{(4.1-3.1)^2 + (-1-(-1))^2[/tex]

Distance = [tex]\sqrt{(1)^2 + (-1+1)^2[/tex]

Distance = [tex]\sqrt{(1)^2}[/tex]

Distance = 1 unit

Hence,

The points are 1 unit apart.

Answer in fraction form =  7/20

Answer in decimal form = 0.35

Answer in percent form = 35%

These are three ways to say the same thing.

======================================================

Explanation:

To get the relative frequency, you divide the number of times heads comes up out of the number of tosses total. Reduce the fraction as much as possible. In this case, 7 and 20 have no factors (other than 1) in common. So the fraction 7/20 cannot be reduced further.

The fraction 7/20 converts to the decimal form 0.35 after using a calculator or long division.

0.35 converts to 35% after moving the decimal over to the right two spots.

Answer:

[tex]x+y= 15---------------------1\\\\5.5x+7.6y= 75.5----------------2[/tex]

Step-by-step explanation:

Given data

let the number of peanuts be x

and the number of cashew be y

so

x+y= 15---------------------1

and

5.5x+7.6y= 75.5----------------2

Hence the system of equation is given as

[tex]x+y= 15---------------------1\\\\5.5x+7.6y= 75.5----------------2[/tex]

Step-by-step explanation:

plato / edmentum answer

Answer:

z=50

y and x=65

Step-by-step explanation:

z=180-130=50 because the total angles on a straight line sum up to 180

x and y=(180-50)/2=65 because 2 angles in an isosceles triangle are equal

Answer:

$1.46

Step-step explanation:

We have to find out what 6.5% of 22.5 is, our keyword is of, so we're multiplying. Our equation is:

22.5 x 0.065 = 1.46

So our tax is $1.46

Answer:

(3x + 11) units

Step-by-step explanation:

The length of a rectangle is 5(x+2) units.

The width of the rectangle measures (2x-1) units.

The difference between the rectangles length and width is given as:

Length - Width

(5(x + 2) - (2x - 1) units

(5x + 10 - 2x + 1) units

(5x - 2x + 10 + 1) units

(3x + 11) units

Therefore, the algebraic expression for the difference between the rectangles length and width is given as:

(3x + 9) units

Answer: c(1 + 0.065)

Step-by-step explanation:

Given:

The side lengths of two cubes are 2.5 yd and 2 yd.

To find:

The side length of third cube.

Solution:

From the given figure it is clear that the cubes are inclined to each other in such a way so that they form a right angle triangle and side length of third cube is the base.

Let x be the side length of the third cube.

Using Pythagoras theorem, we get

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

[tex](2.5)^2=(x)^2+(2)^2[/tex]

[tex]6.25=x^2+4[/tex]

[tex]6.25-4=x^2[/tex]

[tex]2.25=x^2[/tex]

Taking square root on both sides, we get

[tex]x=\pm\sqrt{2.25}[/tex]

[tex]x=\pm 1.5[/tex]

Side cannot be negative. So,

[tex]x=1.5[/tex]

Therefore, the side length of the  third cube is [tex]x=1.5[/tex] yd.

Answer:

75

Step-by-step explanation:

To determine how much of a persons weight is water, multiply 3/4 by their weight.

weight of water =  weight x 3/4                              

100 x 3/4 0r 100 x 0.75 ( same thing)

75

The student weighs 75 lbs underwater

P.S it's not 3.4 it's 3/4 = 75% of our body is made up of water.
