105 grams as percentage of 2kg

Answer: $225

Step-by-step explanation: 900 * .25 = 225

Answer:

$225

Step-by-step explanation:

25 : 100 = x : 900

x = 25 * 900 / 100

x = 25 * 9

x = 225

The required value of RT is 10 units when RS = 7, ST = 3x, and RT = x + 9.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment RT, where the length of line segment RT refers to the distance between its endpoints, R and T.

RS = 7, ST = 3x, and RT = x + 9

R______________S______________T

⇒ RT = RS + ST ....(i)

Substitute the values of RS = 7, ST = 3x, and RT = x + 9,

⇒ x + 9 = 7 + 3x

⇒ 3x - x = 9 - 7

⇒ 2x = 2

⇒ x = 1

Substitute the values of x = 1 in RT = x + 9

So RT = 1 + 9 = 10

Hence, the value of RT is 10 units.

Answer:

y + 1 = 1/2 (x - 3)

Step-by-step explanation:

Point-slope form of an equation is a shortcut, fill-in-the-blank way to write the equation of a line. All you need is slope (usually symbolized with an m) and a point (any point on the line)

Here's Point-slope:

y - Y = m (x - X)

The slope they gave you is 1/2, put that in for the m.

And also fill in 3 for the X and -1 for the Y. Because a point is (X,Y)

Just leave the first y as a y, right there. And leave the first x in the parentheses as an x. They are variables in the equation. They stay letters.

y - -1 = 1/2 (x - 3)

Simplify.

y + 1 = 1/2 (x - 3)

Minus a negative is the same as plus a positive, that's what happened there on the left. Also, when you write it, make sure the 1/2 is beside the parentheses on the right. The parentheses should not be on the bottom with the 2, but just beside the fraction.

The probability of selecting a blonde is 0.40

Probability is the likelihood that something will occur.

In this case, from the twenty students, it should be noted that the number of blondes are 8.

Black hair = 5

Blonde hair = 8

Brown hair = 5

Red hair = 2

Therefore, the probability of choosing a blonde will be:

= Number of blonde / Total students

= 8/20

= 0.40

The probability is 0.40

The value of A rounded to the nearest hundredth is 0 and the value of A rounded to the nearest tenth is 10

From the given number line

The value of A = 7.51

The number line is defined as the straight line that consist of integers in equal intervals. We can also says that the number line is the pictorial representation of numbers on a horizontal line.

The rounding of a number is defined as a number is make it simple by keeping its value intact but closer to the next number. The closer to tenth, hundredth, thousand etc.

The value of A = 7.51

Rounding the rounder to nearest tenth = 10

Rounding the number to nearest hundredth = 0

Hence, the value of A rounded to the nearest hundredth is 0 and the value of A rounded to the nearest tenth is 10.

The amount of money left over after buying the laptop is $55.17.

From the information, the laptop he wants is in stores for $749.99 but is on sale for 25% off and after the discount is removed, a tax rate of 5.75% is added on.

This will be:

= $749.99 - (25% × $749.99)

= $749.99 - $187.50

= $562.49

The addition of the tax will be:

= $562.49 + (5.75% × $562.49)

Between the two variables, the number of cold, snow days, and the amount of hot chocolate sold at a ski resort, there is causation.

For two variables x and y, we have causation when a change in one of the variables causes an immediate change in the other variable as a response.

Here we have the two variables:

x = number of cold, snow days.

y = amount of hot chocolate sold at a ski resort.

Obviously, there is a correlation there, we can even assume that if the days are cold enough, a larger percentage of the people in the ski resort will decide to stay there, and then there is a larger posibility that they will consume hot chocolate there, so yes, there is causation between these two variables.

Every day mass of sunfish is multiplied by factor of (ln(67/50)/6).

In the given question we have a relation between mass of sunfish and time elapsed t. Relation is

M(t) = (67/50) ^(t/6+4) -----(1)

To find out the factor which multiple by mass of sunfish each day, we can take derivative of M(t) function.

Derivative of a function measures the change in fucyion value with respect to change in its argument. It gives rate of change of function with respect to change in given variable value. So, in this problem derivative of mass function M(t) gives the rate of change of M(t) with respect to time , t .. It is represented by dM(t)/ dt.

dM(t)/ dt =( 67/50)^(t/6+4) (1/6)ln(67/50)

We have the used derivative formula d(a^t)/dt = a^t (1) lna

dM(t)/dt = ln(67/50)/6 (67/50)^(t/6+4)

dM(t)/dt = (ln(67/50))/6 M(t)

We can see here that mass funtion is increased by factor ln(67/50)/6 each day.

The exterior angle theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.  

In other words the sum of the remote interior angle is equals to the external angle.

Therefore,

110 = 3x + 2x

Answer:

y = -0.5x + 7

Step-by-step explanation:

Equation of a Line is y = mx + c

where m is the slope and c is the y-intercept

Given two lines are Perpendicular

Then [tex]m_{1} m_{2} =-1[/tex]

So we given Line whose Equation is y = 2x +8

Then [tex]m_{1} =2[/tex] (Coefficient of x)

Since the Line we want is Perpendicular to that line

Then [tex]m_{1} m_{2} =-1[/tex]   ,  [tex]2m_{2} =-1 , m_{2} =\frac{-1}{2}[/tex]

So the Equation of the required Line is y = -0.5x +c

Since the Line passes through (2 , 6) , Then y = 6 when x = 2

By substitution , 6 = -0.5*2 + c  ,   6 = -1 + c

Then c = 6+1 =7

Then the Equation will be y = -0.5x + 7

Answer:   y= -1/2x+7
