Which of the following could be used as a statement in a two-column proof?

Answer: 15 cm

Step-by-step explanation:

just divide 60 by 4 and because a squar has 4 sides and that is it

If  each week it grow by 4% more than it did the previous week by  it grow in 9 week is  17.67cm.

Now let find the growth in 9 week

Growth in 9 week = 1.67cm × [( 1+ 0.04)^9 -1] ÷ [(1+0.04)-1]

Growth in 9 week = 1.67cm × [( 1.04)^9 -1] ÷ (1.04)-1]

Growth in 9 week = 1.67cm ×  [( 1.4233 -1) ÷ 0.04

Growth in 9 week = 1.67cm ×  [0.4233 ÷  0.04

Growth in 9 week = 1.67cm × 10.5825

Growth in 9 week = 17.67cm

Therefore 17.67cm is the 9 week growth.

The Z-score for a GPA of 2.98 is 1.60345

A Z-score is a numerical value or measurement that explains the relationship between a value of data and the mean of a group of values. It will be calculated in terms of standard deviations from the mean.

The formula to calculate the Z -score is given by

                     Z - score =  [tex]\frac{( \bar{x} -\mu) }{\sigma}[/tex]    

Where  [tex]\bar {x}[/tex]  = test value

μ = mean and σ = standard deviation

Here we have

GPAS at CCCOnline are normally distributed with a mean of 2.05 and a standard deviation of 0.58

⇒ mean μ = 2.05

⇒ Standard deviation σ = 0.58  

And we need to find the z-score for a GPA of 2.98

⇒  [tex]\bar {x}[/tex] = 2.98

From above observations

Z - score =  [tex]\frac{( 2.98 -2.05) }{0.58}[/tex]  

= [tex]\frac{( 0.93) }{0.58}[/tex]

= 1.60345  

Therefore,

The Z-score for a GPA of 2.98 is 1.60345

The pressure at an altitude of 5000 m if The atmospheric pressure at sea level is about 101 kilopascals. For every 1000-m increase in altitude, the pressure decreases by about 11.5% is  58.08 kPa.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

The atmospheric pressure, P = 101 kPa,

For every 1000 meters, the pressure decreases by 11.5%,

So at the height of 5000 meter, the % decrease will be 5 × 11.5 = 57.5%,

Now let the 57.5% of 101 kPa be x then,

x = 57.5/100 × 101  kPa,

x = 58.08 kPa,

Therefore, the pressure at an altitude of 5000 m if The atmospheric pressure at sea level is about 101 kilopascals. For every 1000-m increase in altitude, the pressure decreases by about 11.5% is  58.08 kPa.

The value of the angles that are intersected by BC are m/ABC is 35° and m/DBC is 43°

In the given figure the angle ∠ABD is intersected by the straight line BC such that two new angles are formed ,∠ABC and ∠ADC  .

Now from the properties of angles on a 2-dimensional plane we can see that :

m ∠ABC + m ∠ADC  = m ∠ABD

The values of the angles given are:

m ∠ABC = 5x - 5

m ∠ADC = 5x + 3

m ∠ABD = 78°

now we put these above values in the equation:

(5x - 5) + (5x + 3) = 78

or, 10 x - 2 = 78

or, 10 x = 80

or , x = 8

m ∠ABC = 5×8 - 5 = 35°

The materials travel faster on Belt One, considering the constants of the proportional relationships.

A proportional relationship is a linear function with intercept zero in which the output variable symbolized by y is given by the multiplication of the input variable symbolized by x and the constant of proportionality symbolized by k, according to the equation presented as follows:

y = kx

For each belt in this problem, the constant gives the velocity that the materials travel.

For Belt One, the relation is:

y = 157.1x.

Hence the velocity is of 157.1 inches per minute.

For Belt Two, the velocity is obtained as follows:

k = 125.6/2 = 62.8 inches per minute.

157.1 > 62.8, hence it travels faster on Belt One.

The earnings per hour be after working for 15 years is $11.4.

From the given table (2, 6.85), (4, 7.55), (6, 8.25).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

1) Now, put (x1, y1)=(2, 6.85) and (x2, y2)=(4, 7.55) in slope formula, we get

m=(7.55-6.85)/(4-2)

= 0.7/2

= 0.35

Substitute m=0.35 and (x, y)=(2, 6.85) in y=mx+c, we get

6.85=0.35(2)+c

⇒ 6.85=0.7+c

⇒ c=6.85-0.7

⇒ c=6.15

Now, equation is y=0.35x+6.15

2). Put x=15 in the obtained equation, we get

y=0.35×15+6.15

⇒y=$11.4

3). Put y=9.65 in the obtained equation, we get

9.65=0.35x+6.15

⇒0.35x=9.65-6.15

⇒0.35x=3.5

⇒x=3.5/0.35

⇒x=10 years

The y-intercept is what we get when we evaluate in x = 0, then:

y = -0.25*x² + 4x + 3

replacing x by zero we get:

y = -0.25*0² + 4*0 + 3 = 3

The y-intercept is y = 3.

The maximum height is at the vertex, we know this because the leading coefficient is negative, which means that the parabola opens down.

The vertex is at:

The equation of the line passing through y = 3x-1 and (3,2) is y = 3x-7.

According to the question,

We have the following information:

y = 3x-1 and the point through which line is passing is (3,2)

We know that the slope of the given line (denoted by m) is 3.

Now, the following formula is used to find the equation of the line passing through a point:

y-y' = m(x-x')

In this case, we have x' = 3 and y' = 2.

y-2 = 3(x-3)

y-2 = 3x-9

Moving 2 from the left hand side to the right hand side will result in the change of the sign from minus to plus:

y = 3x-9+2

y = 3x-7

Hence, the equation of the line passing through y = 3x-1 and (3,2) is y = 3x-7.
