Tim has read 30 % of a book. He has 56 more pages to finish. How many pages are there in the book?
Answer:
80 pagesStep-by-step explanation:
Let the number of pages is xTim has read 30 % of a bookRemaining
100% - 30% = 70%70% of x is 0.7x
0.7x = 56x = 56/0.7x = 80 pagesAnswer:
[tex] \bf \huge 80 \: pages[/tex]
Step-by-step explanation:
Given that :Tim has read 30 % of a book.He has 56 more pages to finish.to find :How many pages are there in the book ?let us assume :total pages of book is 100•/•explanation :⟼ total book = 100•/•
⟼ Tim has read 30 % of a book.
⟼ 100 - 30 •/• = 70 •/•
⟼ 70 •/• = 56 pages
⟼ 1 •/• = 56 / 70
⟼ 100 •/• = 56 / 70 × 100
⟼ 100 •/• = 56 / 7 × 10
⟼ 100 •/• = 8 × 10
⟼ 100 •/• = 80 pages
∴ tim has 80 total pages in book.

Use the distance formula to find the distance between each pair of points round to the nearest 10th if necessary
Given:
The pairs of points are:
a. A(-6,-4), B(-3,-1)
b. C(3.5,1), D(-4,2.5)
c. X(5,-5), Y(-5,5)
To find:
The distance between the pair of points by using the distance formula.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
a.
Using the distance formula, the distance between the points A(-6,-4) and B(-3,-1) is:
[tex]AB=\sqrt{(-3-(-6))^2+((-1-(-4))^2}[/tex]
[tex]AB=\sqrt{(3)^2+(3)^2}[/tex]
[tex]AB=\sqrt{2(3)^2}[/tex]
[tex]AB=3\sqrt{2}[/tex]
[tex]AB\approx 4.2[/tex]
Therefore, the distance between the points A(-6,-4) and B(-3,-1) is about 4.2 units.
b.
Using the distance formula, the distance between the points C(3.5,1) and D(-4,2.5) is:
[tex]CD=\sqrt{(-4-3.5)^2+(2.5-1)^2}[/tex]
[tex]CD=\sqrt{(-7.5)^2+(1.5)^2}[/tex]
[tex]CD=\sqrt{56.25+2.25 }[/tex]
[tex]CD=\sqrt{58.5 }[/tex]
[tex]CD\approx 7.6[/tex]
Therefore, the distance between the points C(3.5,1) and D(-4,2.5) is about 7.6 units.
c.
Using the distance formula, the distance between the points X(5,-5) and Y(-5,5) is:
[tex]XY=\sqrt{(-5-5)^2+(5-(-5))^2}[/tex]
[tex]XY=\sqrt{(-10)^2+(10)^2}[/tex]
[tex]XY=\sqrt{100+100}[/tex]
[tex]XY=\sqrt{200}[/tex]
[tex]XY\approx 14.1[/tex]
Therefore, the distance between the points X(5,-5) and Y(-5,5) is about 14.1 units.

Find the volume of the rectangular prism.
Write your answer in simplest form.
3/5m
4/9m
2/5 m
Answer:
8/75
Step-by-step explanation:
To find the volume of a rectangular prism you multiply the length, width, and height.
So you do (3/5)*(4/9)*(2/5), and to multiply fractions you multiply the tops by eachother, and then the bottoms by eachother.
So its (3*4*2) over (5*9*5)
which gives you 24/225 which simplifies to 8/75

If the probability that the Islanders will beat the Rangers in a game is 78%, what is
the probability that the Islanders will win at least five out of six games in a series
against the Rangers? Round your answer to the nearest thousandth.
Answer:
Submit Answer
Answer:
(17/25)^5 = 0.145393 = 14.539%
Step-by-step explanation:
78% = 78/100 or 17/25 simplified
probability of winning each game is 17/25
The probability that the Islanders will win at least five out of six games in a series against the Rangers is 0.4.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
The probability that the Islanders will win the Rangers in a game = 78% ⇒ [tex]0.78[/tex]
The probability that the Islanders will lost the Rangers in a game is
⇒ [tex]1-0.78=0.22[/tex]
The probability that the Islanders will win at least five out of six games in a series against the Rangers is
⇒ [tex]6C_{5} (0.78)^{5}(0.22)^{1}[/tex]
⇒ [tex](6)(0.2887)(0.22)[/tex] [∵ [tex]6C_{5} =6[/tex]]
⇒ [tex]0.3811[/tex] ≈ [tex]0.4000[/tex]
Hence we can conclude that the probability that the Islanders will win at least five out of six games in a series against the Rangers is 0.4.

A coach is buying snacks for 22 players on a soccer match chip is a total of $77 to buy each player a bottle of water and energy bar the price of one energy bar is two dollars
The question is incomplete:
A coach is buying snacks for 22 players at a soccer match. She pays a total of $77 to buy each player a bottle of water and an energy bar. The price of one energy bar is $2. Let w equal the price of a bottle of water. Write an equation that represents the situation.
Answer:
x=44+22w, where
x is the total amount paid
w is the price of a bottle of water
Step-by-step explanation:
With the information provided, you can say that the total amount paid is equal to the result of multiplying the price per energy bar for the number of energy bars purchased plus the result of multiplying the price per bottle of water for the number of bottles of water:
price per energy bar= $2
number of enrgy bars= 22
price per bottle of water= w
number of bottles of water= 22
x=(2*22)+(w*22)
x=44+22w, where
x is the total amount paid
w is the price of a bottle of water

The straight line PQ with P(1,6) and Q(-6, 1). PQ is mapped onto P'Q' by a reflection in the line = 2. What are the coordinates of P
Answer:
[tex]P' = (1,-2)[/tex]
Step-by-step explanation:
Given
[tex]P = (1.6)[/tex]
[tex]Q = (-6,1)[/tex]
Reflection over: [tex]y = 2[/tex]
Required
Determine the coordinates of P'
From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2
Since we are to reflect over y = 2, only the y coordinate of P will be affected.
The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]
So, what to do is:
First, calculate the difference between the y coordinates of P and the line of reflection.
The y coordinate of P is 6 and the line of reflection is at y = 2.
So, the difference is: 6 -2 = 4
Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'
y coordinate of P' = 2 - 4 = -2
Hence, the coordinate of P' is: (1,-2)
