Answers

Answer 1

Answer:

80 pages

Step-by-step explanation:

Let the number of pages is xTim has read ​30 % of a book

Remaining

100% - 30% = 70%

70% of x is 0.7x

0.7x = 56x = 56/0.7x = 80 pages
Answer 2

Answer:

[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.

What is the likelihood that a point chosen inside the square will also be inside the circle ?It Chose one : A. is impossible ,B. it is unlikely, C it is likely D. it is certain

Answers

Answer:

C. It is likely

Step-by-step explanation:

Given

See attachment for diagram

For the square.

Let

[tex]Length = L[/tex]

So, the area is:

[tex]Area = Length^2[/tex]

[tex]A_1=L^2[/tex]

The side length of the square equals the diameter of the circle.

So:

[tex]diameter (d) = L[/tex]

The radius is:

[tex]r = \frac{1}{2}d[/tex]

[tex]r = \frac{1}{2}L[/tex]

The area is:

[tex]Area = \pi r^2[/tex]

[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]

[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{28} L^2[/tex]

The likelihood that a point will be common to the square and the circle is:

[tex]Pr = \frac{A_2}{A_1}[/tex]

[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]

[tex]Pr = \frac{22}{28}[/tex]

[tex]Pr = 78.57\%[/tex]

The above probability is greater than 50% but less than 100%.

Hence, it is likely

Answer:

C. Likely

Step-by-step explanation:

all the points are in the circle so it's likely to choose a point inside the circle

Step-by-step explanation:

Given

u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is

u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )

Then

v • w

A traffic camera sits on top of a tower that has a height of 39 ft. The angles of depression of a car on a straight road at the same level as that of the base of the tower and on the same side of the tower are 31°. Calculate the the distance between the base of the poll and the car. Round to the nearest tenth of a foot. *

Answers

Answer:

48ft

Step-by-step explanation:

Distance of car A from the towerConsider ∆ACD tan25 = 50/AC AC  = 50/tan25 = 50/0.4663 = 107.2 ft Distance of car B from the towerConsider ∆BCD tan40 = 50/BC AC  = 50/tan40 = 50/0.8391 = 59.6 ft

Distance from cars A and B AB = AC – BC = 107.2 – 59.6 = 48 ft The distance between the two cars is 48ft

The tip is 11% of the price of the pizza.

The price of the pizza is $452.

The tip is 11% of $452.

To find a percent of a number, change the percent to a decimal and multiply by the number. To change a percent to a decimal, divide the percent by 100 which is the same as moving the decimal point two places to the left.

11% of $452 =

Ben score is 56 out of 79 marks what is his score as a percentage

Answers

Answer:

71%, without rounding 70%

Step-by-step explanation

We know our total number of marks is 79 if we only get 56 out of 79 we take 56/ 79. You'll end up with a number of 0.7088. You will ALWAYS end up with a decimal point. Because its a percentage we move the decimal point over 2 spots making the number 070.88 the 0 in front of of the 70.88 gets removed so you're left with 70.88 so rounded it would be 71%. Hope this helps

Answer:

70.88% or 70.9%(if rounded off)

Step-by-step explanation:

1. 100 ÷ 79 = 1.2658227848

2. 1.2658227848 × 59 = 70.8860759494

3. 70.88 rounded off to the nearest tenths is 70.9
