p(t) = 4t – 1, what is the value of p(4)?

Answer:

(x-2)2=8

Step-by-step explanation:

The probability of selecting one student who is both from math and science is 1/10

There are the total number of student = 300

Out of which,the number of students who are only in Maths  = 120

The number of students who are only in Science  = 50 and  the students who are not from any subject = 100

Total no of students=science student+math students +none

Therefore,the number of student who are from both math and science = Total student - Math student (only) - science student (only) - None

= 300 - 120 - 50 - 100

= 30

That is, there are 30 students who are both from science and math,

Thus, the probability of selecting one student who is both from math and science = 30/300 = 1/10

Answer:

x < 6

Step-by-step explanation:

Step 1: Subtract 12 from both sides.

Thus, the answer is x < 6.

Answer:

Answer:

x=11

Step-by-step explanation:

Subtract 3 from both sides

x+3=2x-8

x+3-3 =2x-8-3

Then simplify it

x=2x-11

Again, subtract 3 from both sides

x-2x=2x-11-2x

Simplify

-x=-11

Divide both sides and simplify and then you get x=11

Answer:

-4

Step-by-step explanation:

The total number of books that are in Francisca's bookcase is 125 books.

Let the total number of books be B.

Given the following data:

Number of paperbacks = 40.

Percentage = 32%.

In this exercise, you're required to determine the total number of books that are in Francisca's bookcase if there she has 40 paperbacks in her bookcase. Thus, we would write a mathematical expression for the word problem.

Translating the word problem into an algebraic expression, we have;

[tex]\frac{32}{100} \times T=40\\\\0.32T=40\\\\T=\frac{40}{0.32}[/tex]

T = 125 books.

Answer:

4 tiles

Step-by-step explanation:

12 * 10 = 120 for each tile

24 * 20 = 480 for entire floor

480/120 = 4

4 tiles

Answer: Below

Step-by-step explanation:

This is a pretty simple problem, so hopefully you catch on to it quickly.

Since we have two measurements for two sides of a rectangle, we know they are referring to square centimeters for both the floor and the tiles. Since the units match up, we can divide.

24 * 20 = 480 cm squared

12 * 10 = 120 cm square.

480/120 = 4 tiles.

Our answer is 4 tiles.

Answer:

[tex]\frac{15}{16}[/tex] ton of pebbles will cover the whole garden.

Step-by-step explanation:

So [tex]\frac{3}{4}[/tex] ton covers [tex]\frac{4}{5}[/tex] of the garden.

Let x be pebbles required to cover the entire garden, we can set up a proportion:

[tex]\frac{\frac{3}{4} }{\frac{4}{5} } =\frac{x}{1}[/tex]

[tex]\frac{3}{4}[/tex] / [tex]\frac{4}{5}[/tex]  = x

[tex]\frac{3}{4}[/tex] * [tex]\frac{5}{4}[/tex] = x

[tex]\frac{15}{16}[/tex] = x

[tex]\frac{15}{16}[/tex] ton of pebbles will cover the whole garden.
