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 = 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:

1/2K - 1/6m

Step-by-step explanation:

You can combine the ones with the same variable.

First, rearrange the equation:

3/4K - 1/4K - 5/6m + 2/3m

Then simplify each part

1/2K - 1/6m

Answer:

[tex] m\widehat{AB} =55 \degree[/tex]

Step-by-step explanation:

[tex] \because m\angle APC=m\angle DPE[/tex]

(Vertical angles)

[tex] \therefore m\widehat {ABC} =m\widehat {DE} [/tex]

(Measure of minor arc is equal to the measure of it's corresponding central angle)

[tex] \therefore m\widehat {AB}+m\widehat {BC} = m\widehat {DE} [/tex]

[tex]\therefore m\widehat{AB} = m\widehat {DE} - m\widehat {BC} \\ \\ m\widehat{AB} =93 \degree - 38 \degree \\ \\ m\widehat{AB} =55 \degree[/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].

If you face South, perform an about face (180-degree turn), and then turn 90 degrees to the right, you will be facing West.

If you are facing South and make an about-face, then turn 90 degrees right, you will be facing West. This is because an about-face means to turn around 180 degrees, so you would now be facing North.

Then, turning 90 degrees to the right from the North would put you in the direction of the West. To summarize, if you start off facing South, making an about-face means turning around 180 degrees to face North.

From there, turning 90 degrees to the right puts you in the direction of the West. Therefore, you would be facing West after making an about-face and turning 90 degrees to the right.

Step-by-step explanation:

Girls = 84

Boys = 84 * 2 = 168

Total = 252

Answer:

Step-by-step explanation:

no of girls in grade 3 = 84

by the question no of boys are twice the number of girls so

no of boys = 2 * 84 = 168

Total no of pupil in grade 3

= 168 + 84

= 252

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:

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.

Answer:

4 and -3

Step-by-step explanation:

So our function is f(x) = x² - x -12

We need to find factors such that 0 = x² - x -12

So, it looks something like this 0 = (x - a)(x - b)

We know that the first term is x², which can only be obtained if we multiply x by another x.

Now, we need to find the other terms a and b. We know that a × b = -12

The correct answer would be that a = 4 and b = -3

0 = (x - 4)(x + 3)

We know this because, if we multiply this out, we get x² + 3x -4x -12, which can be simplified to x² -x -12.

Our zeroes are the values of x that this equation 0 = (x - 4)(x + 3) is true. What values of x will make this zero?

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
