The solution of expression 19×50 is found as 950.
What is defined as the distributive property?This property states that multiplying the product of two or more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.
The distributive property holds true for division the same way that it holds true for multiplication. However, with division, the concept of "breaking apart" or "distributing" can only be applied by dividing the numerator into lesser numbers that are exactly divisible even by divisor.In other words, the distributive property requires a phrase of the form:
A (B + C) can be simplified as A (B + C) = AB + AC.
This same applies foe the subtraction;
Thus, for the given numerical;
= 19×50
Using distributive property.
= (20 - 1)×50
Open the braces;
= 20×50 - 1×50
= 1000 - 50
= 950
Therefore, the solution of the numerical 19×50 is 950.

The least common multiple is the smallest common(of equal value) number. we get this number by multiplying the two numbers by a number value till we get a common number between the two.
For a normally distributed population with a mean of 150 and standard deviation of 25, approximately what percentage of the observations should we expect to lie between 100 and 200?
The percentage of observations which we expect to lie between 100 and 200 is 3.38%
Given, the mean is 150 and
standard deviation(sd) = 25
what percentage of observation lie between 100 and 200.
x + 1sd = 175
x - 1sd = 125
x + 2sd = 200
x - 2sd = 100
x + 3sd = 225
x - 3sd = 7
observation between 100 and 200 lie from x + 1sd
Therefore P(x) = (100-175)÷25
= -3
=3.38%
Hence the percentage of observations that lie between 100 and 200 is 3.38%

rectangle has a length of 35 yards less than 7 times its width. If the area of the rectangle is 6468 square yards, find the length of the rectangle.
Therefore the width of the rectangle is 33 yards
length of the rectangle is 196 yards.
Let the width of the rectangle be 'x'
Given the length of the rectangle = 35 yards less than 7 times the width
= 7x - 35
Given the area of rectangle = 6468 square yards
We know that area of rectangle = length * width
= (7x - 35 ) * x
By comparing both we get,
(7x - 35) * x = 6468
7x² - 35x - 6468 = 0
By dividing the equation by '7' we get
x² - 5x - 924 = 0
Factorize the above equation we get
x² - 33x + 28x - 924 = 0
x ( x - 33) +28 (x - 33 ) = 0
( x - 33 ) ( x + 28 ) = 0
∴ x = 33 , -28
Negative values are not consider
Therefore the width of the rectangle is 33 yards
length of the rectangle = 7(33) - 35
= 231 - 35
= 196 yards

The ball bearing have volumes of 1.6 cm cube and 5.4 cm cube. What is the ratio of their areas?
The ratio of area of the ball bearings will be equal to 4 / 9.
We are given the volume of the ball bearings as:
Volume 1 = 1.6 cm³
Volume 2 = 5.4 cm³
Now, the ratio of their volumes will be equal to:
r = 1.6 / 5.4
r = 16 / 54
r = 8 / 27
Now, we know that, the scale factor will be:
k = ∛8 / 27
k = 2 / 3
Also, we know that, the ratio of their areas is the square of their scale factor.
So, the ratio of area will be equal to:
R = (2 / 3)²
R = 4 / 9
Therefore, we get that, the ratio of area of the ball bearings will be equal to 4 / 9.

The ratio of their areas is 4 / 9.
The scale factor for the linear dimensions of the ball bearings will be the cube root of the volume scale factor:
[tex]$$k=\sqrt[3]{(1.6 / 5.4)}=2 / 3$$[/tex]
Then the scale factor for the areas will be the square of this scale factor: ratio of surface area =(2 / 3)^2=4 / 9
The area is the product of two linear dimensions, so its scale factor is the product of the linear dimension scale factors. That is, the scale factor for area is the square of the linear dimension scale factor.
Similarly, volume is the product of three linear dimensions, so its scale factor is the cube of the linear dimension scale factor.
To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilized. It is employed to change the size of an item.
If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined. A rectangle, for instance, has dimensions of 5 units in length and 2 units in breadth.
The sides of this rectangle will change to 10 units and 4 units, respectively, if the size of the rectangle is increased by a scale factor of two. Therefore, we may use the scale factor to determine the modified figures' dimensions.

The doctor has determined that one reason for the sickness is due to Cameron’s diet and that he has a protein deficiency. A change in his diet is necessary. He must increase the amount of protein that Cameron consumes. To begin this process, Cameron has to figure out how much protein he should consume in a day. Assume that he is 25 years old and weighs 132 lbs. According to the Food and Nutrition Board, Institute of Medicine, National Academies website, adults need 0.66 g/kg/d of protein.
How many grams of protein does he need each day?
Using proportions, it is found that he needs 39.5 grams of protein each day.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
First we have to convert his weight to kg. Each lb has 0.453592 kg, hence his weight in kg is given by:
132 x 0.453592 = 59.87 kg.
Each day, he needs to consume 0.66 g for each kilogram in his body, hence the amount of protein that he needs to consume each day is given by:
0.66 x 59.87 = 39.5.

Answer:
A) y = 0.3x+24
B) 283.5 dollars
Step-by-step explanation:
A) To create an equation in slope-intercept form, we can start by using the numbers the problem gave us and represent them as coordinates. Generally, time is always our x-value.
(230,93)
(530,183)
Now that we have our two coordinates, we can plug them into the slope-intercept formula: y₂-y₁/x₂-x₁ to find our slope.
(183-93)/(530-230) = 0.3
Now that we have our slope, we can plug it into our equation.
y = 0.3x + b
To find our y-intercept, we can take either one of our 2 coordinates (x,y) and plug them into the equation to solve for b.
93 = 0.3(230) + b
93 = 69 + b
93 - 69 = b
b = 24
Now that we have found our y-intercept, we can plug it into b to complete the equation.
y = 0.3x +24
B) If 865 minutes are used, we can plug 865 into x in our equation to find the total cost.
0.3(865) + 24 = 283.5

The Andersons are planning to take a 960-mile trip. They will travel 840 miles by car. What percent of the distance will they not travel by car?
The percent of distance that the Andersons will not travel by car is 12.5%, If they are planning to take a 960-mile trip and they will travel 840 miles by car.
Total distance the Andersons are planning to take is 960-mile
They will travel 840 miles by car
Distance they will not travel by car = total distance - distance travelled by car
= 960 - 840 miles
=120 miles
Percentage formula = (value/ total value) x 100
percent of the distance will they not travel by car =
(total distance - distance travelled by car) x 100/total distance
