solve for the variable c in this equation: a(c + b) = d question 2 options: or c = d/a - b or c = d/a + b or c = b - d/a or c = d/b - a
Answers
Solving the equation a(c + b) = d for variable c, the variable c = (d/a) – b. (Option A)
Equation refers to a statement that represents an equality of values of two mathematical expressions and is indicated by the sign =.
In the given equation a(c + b) = d, in order to solve for the variable c, we must isolate the c variable at one side and collect other variables on the other side of the equation.
Given equation is:
a(c + b) = d
Divide both sides by a:
(1/a)*a(c + b) = d/a
c + b = d/a
Subtract b from both sides:
c + b – b = (d/a) - b
c = (d/a) – b

a satellite in a circular orbit 1250 kilometers above earth makes one complete revolution every 110 minutes. find its linear speed, round your answer to 2 decimal places. assume that earth is a sphere of radius 6400 kilometers.
Answers
Its linear speed would be 1637.75 miles/hour
Vt = 435,49 Km/min
Vt = 26129 Km/hour
Vt = 16630, 35 miles/hour
The distance from the earth center up to the satellite position is:
Earth radius + distance above the earth
radius of satellite 6400 + 1250 = 7650 Km
linear speed = Vt = 2π*r/T
where
r is the radius of the satellite and T period = 110 min
Then
Vt = 6,28* 7650 / 110
Vt = 4804/110
Vt = 43,674.54 Km/min
To get it in Km/h we must multiply by 60
Vt = 26204m/hour
And finally, to get it in miles per hour we divide it by 16
Vt = 1637.75 miles/hour

Find the slope
Answers
The slope is -1/3.
The slope of a line, also known as the gradient is defined as the value of the steepness or the direction of a line in a coordinate plane. Slope can be calculated using different methods, given the equation of a line or the coordinates of points lying on the straight line.
Slope = m = tan θ = (y2 - y1)/(x2 - x1)
Slope = 2−1 / 2−1
= 4-0 / -2-10

Step-by-step explanation:
Inequality could the theme park use to determine the Total number of tickets that must be sold in a day to make a profit is 159.50a + 109c ≥5,490,000.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Given, Tickets for an amusement park are available for adults (a) for $159.50 and for kids (c) for $109.00. The theme park requires daily revenue of at least $5.49 million to turn a profit.
total earning per day = 159.50a + 109c
this should be greater than (>) or at least equal to 5.49 million.
Therefore, The total number of tickets that must be sold in a day to generate a profit is 159.50a + 109c ≥ 5,490,000. Inequality might be used by the theme park to calculate this amount.

a ladder reaches a maximum length of about 23 m. for any ladder to be safe, the angle it makes with the ground should be between 65° and 70°. one storey of a building is about 4 m. a fire breaks out on the fifth storey of a building. will the extension ladder reach the fifth storey safely?
Answers
Answer:
Given,
Let's assume the maximum safe height of wall = h
angle formed between ladder and ground = 70°
length of ladder = 16 ft
From the given data, it can be seen that ladder will form a right angle triangle structure with the wall
So,from the concept of trigonometry,
Sin70^o\ =\ \dfrac{\textrm{maximum safe height of wall}}{\textrm{length of ladder}}Sin70
o
=
length of ladder
maximum safe height of wall
= > Sin70^o\ =\ \dfrac{h}{16\ ft}=>Sin70
o
=
16 ft
h
= > \ h\ =\ 16\times Sin70^o=> h = 16×Sin70
o
=> h = 16 x 0.9396
=> h = 15.03 ft

An urn has 4 green balls and 6 red balls. A experiment consists of selecting 5 balls from the urn without replacement. Find the expected number of red balls chosen, and its variance.
Answers
The expected variance of red balls chosen is 2/3 from the urn.
Define the term variance?Variability is measured by the variance. The average of the squared variance is used to calculate it. The degree of dispersion within your data set is indicated by variance. The variance is greater in respect to the mean the more dispersed the data.Six red balls and four green balls are in an urn.
Till a urn is empty, we take balls out of it one at a time without replacing them and noting their order of the colors.
Let X represent the proportion of red balls in the initial five drawings.Y represent the proportion in the next five draws.The, the variance is found as-
Variance(X,Y) = E(XY) - E(X).E(Y).E(XY)
E(XY) = 25×(6/10)(4/9)
E(X) = 5×(6/10)
E(Y) = 5×(4/10)
Thus,
Variance(X,Y) = 25(6/10)(4/9) - 25(6/10)(4/10)
Variance(X,Y) = 2/3
Thus, the variance for choosing red balls is 2/3.

Angle C must measure (90 − 40) degrees.
Angle C must measure (90 − 30) degrees.
Answers
The correct measure of the third angle in the triangle as we can see is 40 degrees.
What is a right angled triangle?We know that a right angle triangle is one in which one of the angles of the triangle is 90 degrees. If we know that one of the angles of the triangle has been given as 90 degrees, it then follows that the other two angles would have to be complementary.
Let us remind ourselves here and now that the angles that we say that they are complementary are the angles that do add up to about an angle of ninety degrees.
Having said this, we can see that the third angle is the angle A measures 90 degrees and angle B measures 50 degrees, it then follows that the third angle must have to measure 40 degrees. This would now give the correct balance of all the angles in the triangle.

Which form of a linear equation do you prefer to use: slope-intercept form or point-slope form? list advantages and disadvantages of each. Compare your answer with a classmate's and discuss any differences.
Answers
Both slope-intercept form and point-slope form are equally important and useful, and easy to use. The advantages and disadvantages of both forms of linear equations are shown below.
Point-slope form:Advantages: One of the three forms we can use to express a straight line is the point-slope form, also referred to as the point-gradient form.
This form is helpful since it allows us to find the equation of the line by only knowing the slope and one point along the line.
Disadvantages: Since vertical lines have arbitrary slopes, one limitation of the point-slope form is that it cannot be used to describe the equation of a vertical line.
Standard form and slope-intercept form are two additional frequently used forms.
Slope-intercept:
Advantages: The slope of the line and the y-intercept are both clearly displayed in slope-intercept form.
The slope of the line and the single point the line passes through are both plainly displayed in point-slope form.
When working with equation systems, the standard form is more convenient. (specifically, to locate the intersection with matrices).
Disadvantages: Slope-intercept form has the same drawbacks as a point-slope form in that vertical lines cannot be represented since the slope of a vertical line is ill-defined.
Therefore, both slope-intercept form and point-slope form are equally important and useful, and easy to use. The advantages and disadvantages of both forms of linear equations are shown below.
