Answer:
Place Value
Step-by-step explanation:
To Find:in a multi-digit number, the number place that a digit is in determines it's?
Solution :
The number place that a digit is in determines it's PLACE VALUE
Definition of place value : Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Thus in a multi-digit number, the number place that a digit is in determines it's PLACE VALUE.
Eg . 389
Since the digit 8 is on tens place
So, it makes us to determine its place value
Place value of 8 is 80
Hence in a multi-digit number, the number place that a digit is in determines it's PLACE VALUE.
factor 9x^4 -225y^8 10 points
Answer:
9(x² + 5y⁴) (x² - 5y⁴)
Step-by-step explanation:
9x⁴ - 225y⁸
factor out a 9
9(x⁴ - 25y⁸)
factor (x⁴ - 25y⁸)
(x⁴ - 25y⁸)
x² • x² = x⁴
5y⁴ • -5y⁴ = -25y⁸
(x² + 5y⁴) (x² - 5y⁴)
↓
9(x² + 5y⁴) (x² - 5y⁴)
the fourth term of a sequence is 40. write the first 5 terms of two different sequences that satisfy that condition
Answer:
A.P. : 10, 20, 30, 40, 50
G.P. : 5, 10, 20, 40, 80 .
Step-by-step explanation:
It is given that fourth term of a sequence is 40.
It is not given that whether the sequence is A.P. or G.P.
We need to write two different sequences that satisfy the given condition.
For A.P.,
Required sequence : 10, 20, 30, 40, 50
Here, first term is 10, common difference is 10.
For G.P.,
Required sequence : 5, 10, 20, 40, 80
Here, first term is 5, common ratio is 2.
Therefore, the two sequences are 10, 20, 30, 40, 50 and 5, 10, 20, 40, 80 .
Evaluate -3 to the 2 power + (2-6)(10)
pls hurry i need help on it
Answer:
-31
Step-by-step explanation:
-3 to the power of 2 means -3*-3 and since negative multiplied by negative is positive, that will give 9
9 + (2-6)(10)
9+-4(10)
9+ -40
9-40
-31
A come and a pyramid has equal heights and volumes.if the base area of the pyramid is 154cm2.find the radius of the cone.
Answer:
Radius = 8.575 cm
Step-by-step explanation:
Formula for volume of a pyramid is;
V_p = ½Ah
Where A is area of base and h is height
Also, formula for volume of cone is given as;
V_c = ⅓πr²h
Now, we are told that V_p = V_c and that h is the same for both shapes.
Thus ;
½Ah = ⅓πr²h
h will cancel out to give;
½A = ⅓πr²
Cross multiply to give;
3A/2π = r²
Base area of pyramid is given as 154 cm². Thus;
(3 × 154)/2π = r²
r = √((3 × 154)/2π
r = 8.575 cm
Simplify this expression

What’s f(g(x)) if f(x) = 3x + 7 and g(x) = 6x - 5
Answer:
f(g(x)) = 18x - 8
Step-by-step explanation:
f(x) = 3x + 7 and g(x) = 6x - 5
Substitute g(x) into f(x):
f(g(x)) = 3(6x - 5) + 7
Distribute the 3 from outside the parentheses:
f(g(x)) = (18x - 15) + 7
Combine like terms:
f(g(x)) = 18x - 8

Three spherical balls with radius r are contained in a rectangular box. two of the balls are each touching 5 sides of the rectangular box and the middle ball. the middle ball also touches four sides of the rectangular box. What is the volume of the space between the balls and the rectangular box? This is a SAT question and is no calculator. Show all the work Answer is 4r^3(6-pi)
Answer:
[tex]\bold{4r^3 (6-\pi)}[/tex]
Step-by-step explanation:
Let us try to visualize the given situation in the form of 2 Dimensional image as shown in the attached diagram.
Let the Diameter of spherical balls be D.
As the spherical balls are completely fit in the rectangular box, the sides of box become:
[tex]D \times D\times (3 \times D)[/tex] OR [tex]D\times D\times 3D[/tex]
We know that Diameter is twice of radius.
Therefore [tex]D = 2r[/tex]
So, the dimensions of rectangular box becomes:
[tex]2r \times 2r \times 6r[/tex]
Volume of a rectangular box is given as:
[tex]V = Length \times Width \times Height\\\Rightarrow V = 2r\times 2r\times 6r = \bold{24r^3}[/tex]
Now, let us find out the volume of each spherical ball.
Volume of a sphere with radius 'r' is given as:
[tex]V_{sphere} = \dfrac{4}{3}\pi r^3[/tex]
Volume of 3 spheres = [tex]3\times \frac{4}{3}\pi r^3 =4\pi r^3[/tex]
Now, the volume of space between the balls and rectangular box is = Volume of rectangular box - Volume of 3 balls
[tex]24r^3 - 4\pi r^3\\\Rightarrow \bold{4r^3 (6-\pi)}[/tex]
What are the zeros of f(x) 3x^2+9x+12
Answer:
there are no zeros in f(x)
Step-by-step explanation:
[tex]f(x)=3x^2+9x+12\\\\f(x)=0\\\\0=3x^2+9x+12\\\\[/tex]
to know if the equation has real solutions we have to know if
[tex]b^2-4ac\geq 0[/tex]
a=3
b=9
c=12
[tex]9^2-4*3*12\\\\=81-144\\\\=-63[/tex]
so there aren't real solutions
hence there aren't any zeros in f(x)
Use the table to find the number of miles x you need to bike on friday so that the mean number of miles biked per day is 5
Answer:
Friday needs 11 bikes
Step-by-step explanation:
Mean = (summation of all the numbers)/the total number of the given data
(summation of all the numbers)
= 3.5+5.5+0+5+x
(summation of all the numbers)
= 14+x
the total number of the given data
=5
Mean= 5
Mean= (summation of all the numbers)/the total number of the given data
5= (14+x)/5
25= 14+x
25-14=x
11= x
A carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.
What is the ratio of the total length of the 2-inch screws to the total length of all the screws? Do not reduce.
Answer:
48/132
Step-by-step explanation:
The length of 1.5-inch screws is ...
36 × 1.5 in = 54 in
The length of 2-inch screws is ...
24 × 2 in = 48 in
The length of 2.5-inch screws is ...
12 × 2.5 = 30 in
The total length of all screws is ...
54 in + 48 in + 30 in = 132 in
Then the ratio of 2-in screw length to total screw length is ...
2-in : total = 48 : 132

what is 1/4 * 32 I need help please
Answer: 8
Step-by-step explanation: Think of the 32 in this problem as 32/1.
So rewriting, we have 1/4 × 32/1.
Now, the 4 and 32 cross-cancel to 1 and 8.
So we have 8/1 or just 8.

Answer:
60
Step-by-step explanation:
1, Extand line y for which y intercepts CB at point K
2, line y is a straight line and thus KAB=180-110=70
3, AY parallel to CX thus angle CKA=130 which is a alternative angle of BCX (if you can't see then try to extend CX as well
4,BKA=180-130=50 as BC is a straight line
5, the sum of interior angle of a triangle is 180, and we have KAB and BKA, thus angle ABC = 180-KAB-BKA=180-70-50=60

- 4(2x - 3)
Answer:
-8x + 12
Step-by-step explanation:
We can use the distributive property of multiplication which states that a(b + c) = a * b + a * c. Therefore:
-4(2x - 3)
= -4 * 2x - 4 * (-3)
= -8x + 12
Answer: -8x -12
Step-by-step explanation:
Multiply -4 by 2x getting -8x
Then Multiply -4 by 3 getting 12
Since you can't subtract 12 from -8x this is the simplest way

"Two more than three times a number is seven"
Add 2 to 3n and set it equal to 7.
The equation that represents the mentioned condition will be 3n + 2 = 7. Then the correct option is C.
How to convert the sentence into an expression?The expression is defined as the relations of the numbers and the variables combined together to form the equation by the use of mathematical algebraic symbols like equal greater than or less than.
From the statement, two more than three times a number is seven.
Let n be the number. The three times a number is then written as,
⇒ 3n
And the expression that is 2 more than 3n is written as follows:
⇒ 2 + 3n
The expression equals 7. The equation is then given as,
3n + 2 = 7
The equation that represents the mentioned condition will be 3n + 2 = 7. Then the correct option is C.
