Answer:

21.25 days

Step-by-step explanation:

We first need to find the rate that he read the book for the first 5 days:

180 (pages)/5 (days)= 36

So he reads 36 pages a day. Now we need to find how many days it will take him to read the whole book, while reading 36 pages a day.

765 (total pages)/36 (pages he reads in a day) = 21.25

Have a wonderful day, my friend.

Answer:

y = -3x + 4

Step-by-step explanation:

y = mx + b

y = y coordinate

m = slope (rise/run, up/over, change in y/change in x)

x = x coordinate

b = y intercept (where the line crosses the y-axis.

1. Write the equation                                                            y = mx + b

2. Substitute the numbers in the proper place.                y = 3/1 x + 4

3. Check for the type of slope- (positive or negative)      y = -3x + 4

    (Downhill slopes are always negative.)

Answer:

y = 52

Step-by-step explanation:

y/4 - 7 = 6 (get the y isolated)

y/4 = 13 (add 7 to both sides)

y = 52 (multiply 4 on both sides)

Answer:

Step-by-step explanation:

S=4πr²

ds/dt=4π×2r×dr/dt=8πr dr/dt

dr/dt=60 cm/min

ds/dt=8π×60r=480πr

r=16,t=0

at t=2,r=16+32=48 cm

so ds/dt=480π×48=23040 πcm²≈72382.79 cm²

Answer:

0.8 meters

Step-by-step explanation:

The scale factor is 1:250 (can be rewritten as 1/250 or 1 to 250).

1/250 × 212 = 0.848 Meters

Round to the nearest tenth, the scale model will be 0.8 meters.

OR: SET UP A PROPORTION:

[tex] \frac{250}{1} \times \frac{212}{x} [/tex]

cross-multiply

[tex]250x = 212[/tex]

[tex]x = 0.848[/tex]

The solution of the system of linear equations is [tex]x = 3[/tex] and [tex]y = -4[/tex].

In this question, we notice that given system of linear equations consist of two equations and two variables, which means that solution is unique and can be found by graphic means. We proceed to graph each line with a graphing tool and label the point, in which both lines intersect each other.

The outcome from the graphing tool is presented below as attachment. In a nutshell, the solution of the system of linear equations is [tex]x = 3[/tex] and [tex]y = -4[/tex].

Answer:

p = 3

Step-by-step explanation:

The price elasticity of demand at the equilibrium points occurs when quantity demand equals quantity supply.

So,

72-8p= -24 +24p

Taking like terms together,

72+24 = 24p+8p

96 = 32p

p = 3

Hence, the price elasticity of demand is at p = 3.

Answer:

B = 243°

Step-by-step explanation:

Full revolution = 360°

360 - 117 = 243

Answer:

243 degrees

Step-by-step explanation:

The angle of a full circle = 360 degrees

360 - 117 = 243

The solution of the system of equations is (4, 2).

A system of equations is graphed on the set of axes below.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The solution to a system of linear equations is the point at which the lines representing the linear equations intersect.

From the given graph, two lines intersecting at the point (4, 2)

Hence, the solution of the system of equations is (4, 2).

Answer:

C = 75 in

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in.

This means that [tex]\mu = 69, \sigma = 2.9[/tex]

Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team.

This is the 100 - 2.5 = 97.5th percentile, which is X when Z has a pvalue of 0.975, so X when Z = 1.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.96 = \frac{X - 69}{2.9}[/tex]

[tex]X - 69 = 1.96*2.9[/tex]

[tex]X = 74.7[/tex]

Rounded to the nearest inch,

C = 75 in

Step-by-step explanation:

Answer:

x = -4.

n = -2.

v = -5.

Step-by-step explanation:

18 = -4x + 2

18 - 2 = -4x

x = 16/-4

x = -4.

6 + 2n = 2

2n = 2 - 6 = -4

n = -2.

5v + 8 = -17

5v = -17 - 8

5v = -25

v = -5.
