How many possible 10-digit phone numbers are possible (7 digits plus the
area code)? Type your answer into the box.
Using the Fundamental Counting Theorem, it is found that 3,250,000,000 phone numbers are possible.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
For the first 3 digits, which correspond to the area code, there are 325 options in total, that is, [tex]n_1n_2n_3 = 325[/tex].For the final 7 digits, each of them has 10 options.Hence:
[tex]T = 325 \times 10^7 = 3,250,000,000[/tex]
3,250,000,000 phone numbers are possible.

Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle? the triangle is acute because 22 52 > 42. the triangle is acute because 2 4 > 5. the triangle is not acute because 22 42 < 52. the triangle is not acute because 22 < 42 52.
A triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle Thus, the triangle is not acute because 2² + 4² < 5².
What is the acute angle?An acute angle is defined as the measure of an angle that is less than 90 degrees.
The square of the hypotenuse of a right triangle with the given sides would be 2² +4² = 20.
So, that hypotenuse would be √20, about 4.47.
The long side of this triangle is longer than that, hence the angle opposite is larger than 90°. The triangle with sides 2, 4, and 5 is an obtuse triangle.
The triangle is not acute because 2² + 4² < 5²

Find the surface area of the cylinder
Answer:
Surface area of the cylinder is 377 cm² (approximately)Step-by-step explanation:
Given :-
Radius of the cylinder = 6cmHeight of the cylinder = 4 cmTo find :-
Surface areaSolution :-
We know that,
Surface area of cylinder = 2πr(h + r)Substituting the required values,
➝ Surface area= 2 × 22/7 × 6 (6 + 4)
➝ Surface area = 264/7 (10)
➝ Surface area = 2640/7
➝ Surface area ≈ 377 cm²
Hence,
Surface area of the cylinder is 377 cm² (approximately)After refering the diagram given in attachment, we clearly came to knew that the radius of the cylinder is 6 cm and height of that cylinder is 4 cm.
Radius (r) = 6 cm Height (h) = 4 cmAs we know that total surface area of cylinder is calculated by the formula :
T.S.A. = 2πr (h + r)Where,
r is radius h is height Value of π is 22/7★ Putting the values in the formula :
>> T.S.A. = 2πr (h + r)
>> T.S.A. = 2 × (22/7) × 6 (6 + 4)
>> T.S.A. = 2 × (22/7) × 6 (10)
>> T.S.A. = 2 × (22/7) × 6 × 10
>> T.S.A. = 2 × (22/7) × 60
>> T.S.A. = (44 / 7) × 60
>> T.S.A. = 44 × 60 / 7
>> T.S.A. = 2640 / 7
>> T.S.A. = 377
★ Therefore,

7/8 inches
1 1/8 inches
5/8 inches
3/8 inches
The dot plot shows the frequency or length of the tadpoles
The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches
How to determine the total length?From the dot plot, we have the following parameters:
3 tadpoles have a length of 1/82 tadpoles have a length of 1/4So, the total length is:
Total = 3 * 1/8 + 2 * 1/4
Evaluate the product
Total = 3/8 + 1/2
Rewrite as;
Total = 3/8 + 4/8
Evaluate the sum
Total = 7/8
Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

Represent the depths as integers.
Which plant is closer to the surface?
Step-by-step explanation:
here will take the earth's surface as 0.
hence,
the first hole that Sally dug is 5 feet below the surface making its integer -5
the second hole Sally dug was 8 feet below the surface making its integer -8
therefore, the roses are closest to the surface.
Two spheres have volumes of 8π cm3 and 64π cm3. if the surface area of the smaller sphere is 16π cm2, what is the surface area of the larger sphere? 64π cm2 96π cm2 128π cm2 256π cm2
The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.
The volume of the larger sphere = 64π cm³
let us take the radius of the larger sphere r
So, 4/3*π*r³ =64π
r³=48
r=2∛6
What is the surface area of a sphere?The surface area of a sphere with radius r is 4πr².
So, the surface area of the larger sphere = 4π(2∛6)²
The surface area of the larger sphere = 16π∛36
Hence, The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

The unshaded area inside the figure to the right is 648 in.² Use this fact to write an equation involving x. Then solve the equation to find the value of x.
Length of rectangle is 40 inches
Width of rectangle is 22 inches
Border inside rectangle is x
The second order polynomial that involves the variable x (border inside the rectangle) and associated to the unshaded area is x² - 62 · x + 232 = 0.
How to derive an expression for the area of an unshaded region of a rectangle
The area of a rectangle (A), in square inches, is equal to the product of its width (w), in inches, and its height (h), in inches. According to the figure, we have two proportional rectangles and we need to derive an expression that describes the value of the unshaded area.
If we know that A = 648 in², w = 22 - x and h = 40 - x, then the expression is derived below:
A = w · h
(22 - x) · (40 - x) = 648
40 · (22 - x) - x · (22 - x) = 648
880 - 40 · x - 22 · x + x² = 648
x² - 62 · x + 232 = 0

The maximum revenue of the craftsman is an illustration of objective function
The craftsman can at most make $500, if he makes 100 bracelets
How to determine the maximum revenue?Represent bracelet with b and necklace with n.
From the question, we have:
b n Total
Unit 10 20 1000
Time 10 40 1600
Cost 5 7.5
So, we have the objective function to be:
Max C = 5b + 7.5n
And the constraints are:
10b + 20n ≤ 1000
10b + 40n ≤ 1600
b ≥ 0
n ≥ 0
From the given graph of the constraints, we have the following feasible points
(b,n) = (0,0) (40,30) (0,50) and (100,0)
Substitute these values in the objective function
C(0,0) = 5(0) + 7.5(0) = 0
C(40,30) = 5(40) + 7.5(30) = 425
C(0,50) = 5(0) + 7.5(50) = 375
C(100,0) = 5(100) + 7.5(0) = 500
The maximum revenue is at the point (100,0)
Hence, the craftsman can at most make $500, if he makes 100 bracelets
