there are more than 200 pages but fewer than 800 in my book. all thre digits of my number are the same. the number is divisible by 9. how many pages sre in my book

Step-by-step explanation:

X-intercept is where the line crosses the x-axis or where y = 0

So, put y = 0 in the given equation

4x + 2(0) = 12

4x = 12

x = 12/4

x = 3

The probability of selecting at least one defective item at random is 0.3017.

The probability of an event occurring at least once will be calculated as the complement of the probability of the event never occurring. You can use exponents to multiply the number of events that occurred when calculating this amount.

Defect rate = P(defect) = 0.05

Probability is defined as the required outcome divided by the total number of possible outcomes.

P( at least 1 is defective) = 1 - P(none is defective)

P(not defective) = 1 - P(defective) = 1 - 0.05 = 0.95

P(none is defective) = P(non defective)^7

P(none defective) = 0.95× 0.95 × 0.95 × 0.95 × 0.95× 0.95× 0.95=0.6983

P(at least one is defective) = 1 - 0.6983 = 0.3017

Therefore, probability of at least one defective item is 0.3017.

Answer: 1080 [tex]cm^{2}[/tex]

Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).

The sides of the triangular base are:

b1 = 13 in.

b2 = 14 in.

b3 = 15 in.

The triangular base is a right triangle, and so the height is one of our sides. We will use

h = 12 in.

The length of the prism is

l = 20 in.

total surface area = bh + (b1+b2+b3)*l

bh = 12*20 = 240 [tex]cm^{2}[/tex]

l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840 [tex]cm^{2}[/tex]

The first washing machine appear to have more savings in cost

The question is a percentage problem

The first is marked down by ​50%

= 50 percent

= 50 / 100

What is a triangle?

A triangle is a three sided two dimensional figure. A triangle has three sides and three interior angles. The sum of the interior angles of a triangle is 180°

Let a = 8, b = 13 and let the third side be c

We know sum of two sides of a triangle is always greater than the third side

a < b + c

8 < 13 + c

c > 8 - 13
c > -5, which is obvious

b < c + a

13 < c  + 8

c > 13 - 8

c > 5

c < a + b

Answer:

5√3

Step-by-step explanation:

There are two triangles shown in the image.

First one is a 45°-45°-90° right triangle with side lengths represented with a-a-a√2 respectively to the angle measures.

The second triangle is 30°-60°-90° special right triangle with side lengths represented with b-b√3-2b respectively to the angle measures.

In first triangle hypotenuse (the side length represented with a√2) is given as 10√2 so a = 10.

This is also the measure of hypotenuse for the second triangle which is represented with 2b, so b = 5 in this case.

x is the side length that sees angle measure 60° which we said is represented with b√3, we said b = 5 so the value of x = 5√3 the answer is the first option.

For the given values of the arithmetic sequence d = -2 , a₂₁ = 18,then the value of a₁ = 58.

As given in the question,

Given values of the arithmetic sequence :

Common difference 'd' = -2

Twenty first term a₂₁ = 18

Formula for the nth term of arithmetic sequence with common difference 'd' and first term a₁ is given by:

aₙ = a₁ + (n -1) d

Substitute the value n =21 , a₂₁ =18 and d = -2 in the above equation we get,

⇒a₂₁ = a₁ + (21 -1)(-2)

⇒18 = a₁ + 20(-2)

⇒ a₁ = 18 +40

⇒a₁ = 58

Therefore, for the given values of the arithmetic sequence d = -2 ,

a₂₁ = 18,then the value of a₁ = 58.

The function's y = 3(x + 5)² +11 width will be narrower.

In mathematics, a function from a set x to a set y assigns each element of x precisely one element of y. The subsets x and y are referenced to as the function's domain and codomain, correspondingly. A relationship between a number of inputs and one output per input is referred to as a function. Simply described, a function is an association between inputs in which each piece of data is connected to exactly one output. There is a domain and a codomain, or range, for every function. A function is a type of rule that produces one output from one input. y = x² is a good illustration of this. Any information for x yields a single output for y.

A parabola is made narrow by a large positive value of a and wide by a large positive value of a that is close to 0.

Compare the given equation y = 3(x + 5)² + 11 with y = x² + c

So, a = 3

Therefore, the function will be narrower.

The sum of the first 16 terms of the defined arithmetic sequence is given as follows:

-520/16.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant, being called common difference d.

The nth term of an arithmetic sequence is given by the equation presented as follows, called general equation:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term of the arithmetic sequence.

The sum of the first n terms is given by the equation presented as follows:

[tex]S_n = \frac{n(a_1 + a_n)}{2}[/tex]

The sequence in this problem is defined as follows:

[tex]a_n = \frac{5}{8} - \frac{5}{16}n[/tex]

The first term is of:

[tex]a_1 = \frac{5}{8} - \frac{5}{16} = \frac{5}{16}[/tex]

Hence the 16th term of the sequence is of:

[tex]a_{16} = \frac{5}{8} - \frac{5}{16}(16) = \frac{5}{8} - 5 = -\frac{35}{8}[/tex]

Hence the sum of the first 16 terms of the arithmetic sequence is defined as follows:

[tex]S_{16} = 8\left(\frac{5}{16} - \frac{35}{8}\right) = 8 \times \left(-\frac{65}{16}\right) = -\frac{520}{16}[/tex]

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined.

This ultimately implies that, a domain is the set of all possible input numerical values or numbers (x-values) to a function and the domain of a graph comprises all the input numerical values which are located on the x-coordinate.

In order to determine the domain of this function, we would equate the x-value to zero and then evaluate as follows:

Step-by-step explanation:

The mason should order 250 cubic yards of grit to use all the cement.

It is given that the mixture has 20 cubic yards of grit for 4 cubic yards of cement.

So the unit rate for the number of cubic yards of grit for per unit of cement is given by : 20 ÷ 4 = 5 cubic yards.

Now amount of grit required for 50 cubic yards of cement

= 50 × 5 = 250 cubic yards.

By utilising 1 as the denominator, a unit rate compares two quantities while using the second quantity as the unit of measurement. If someone runs three kilometers in 30 minutes, they have ran one mile.

Miles per minute is a unit of measurement for how far something is moving in a certain amount of time. For unit rate, the quantity value 1 is always used.
