__________
Step-by-step explanation:
Note: " (6)(6)(6) " ; is the value of the
[number "6" ; multiplied by that same number, "6" —two additional times;
→ so the same number, "6" ; being multiplied: "3 (three) times'
= 6 * 6 * 6 = 6³ ; that is: the number "6", raised to the third power (as an exponent);
→ since: there are 3 (three) of the same numbers being multiplied;
⇒ hence the exponent, "3" .
__________
The answer is: " 6³ " .

Factorisation of 3p^3 + 9p^2- 15pq
Answer:
STEP 1:Equation at the end of step 1 ((3 • (p3)) + 32p2) - 210p
STEP 2 :Equation at the end of step 2: (3p3 + 32p2) - 210p
STEP 3:STEP 4:
Pulling out like terms 4.1 Pull out like factors : 3p3 + 9p2 - 210p = 3p • (p2 + 3p - 70)
Trying to factor by splitting the middle term 4.2 Factoring p2 + 3p - 70 The first term is, p2 its coefficient is 1 .The middle term is, +3p its coefficient is 3 .The last term, "the constant", is -70 Step-1 : Multiply the coefficient of the first term by the constant 1 • -70 = -70 Step-2 : Find two factors of -70 whose sum equals the coefficient of the middle term,
which is 3 . -70 + 1 = -69 -35 + 2 = -33 -14 + 5 = -9 -10 + 7 = -3 -7 + 10 = 3 That's itStep-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 10 p2 - 7p + 10p - 70
Step-4 : Add up the first 2 terms, pulling out like factors : p • (p-7) Add up the last 2 terms, pulling out common factors : 10 • (p-7)Step-5 : Add up the four terms of step 4 : (p+10) • (p-7) Which is the desired factorization
Final result : 3p • (p + 10) • (p - 7)

The product of the two terms [tex]\dfrac{4n}{(4n-4)} \times \dfrac{(n-1)}{(n+1)}[/tex] is [tex]\dfrac{n}{(n+1)}[/tex].
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25.
The product of the two fractions can be written as,
[tex]\dfrac{4n}{(4n-4)} \times \dfrac{(n-1)}{(n+1)}[/tex]
Taking 4 as the common term from both numerator and denominator of the first fraction, therefore,
[tex]\dfrac{4n}{4(n-1)} \times \dfrac{(n-1)}{(n+1)}\\\\=\dfrac{n}{(n-1)} \times \dfrac{(n-1)}{(n+1)}\\\\[/tex]
Now, cancelling the common factor from the numerator and the denominator, we will get,
[tex]=\dfrac{n}{(n-1)} \times \dfrac{(n-1)}{(n+1)}\\\\\\=\dfrac{n}{(n+1)}[/tex]
Hence, the product of the two terms [tex]\dfrac{4n}{(4n-4)} \times \dfrac{(n-1)}{(n+1)}[/tex] is [tex]\dfrac{n}{(n+1)}[/tex].

At a shelter 15% of the dogs are puppies there are 60 dogs at the shelter. How many are puppies?
Explanation:
One method is to do the steps like this
15% of 60 = 0.15*60 = 9
Or you can solve like this
part/whole = percent/100
x/60 = 15/100
100x = 60*15
100x = 900
x = 900/100

The radius of a circle is 16 millimeters. What is the circle's area?
Use 3.14 for .
please answer windowesssssssssssssss
Answer:
803.84 millimeters²
Step-by-step explanation:
How do we find the area of a circle?
The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.Solving
[tex]3.14 *16^2[/tex] [tex]3.14*256[/tex] [tex]803.84[/tex]Therefore, the area is 803.84 square millimeters.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Solution:
We know that:
Radius = r = 16 mmArea of circle = (π)(r²)Finding the area of the circle:
Area of circle = (3.14)(16²)=> Area of circle = 3.14 x 16²=> Area of circle = 3.14 x 256=> Area of circle = 803.84 mm²Rewrite each algebraic expression with as few terms as possible using the Commutative and Associative Properties. (2x - 2y) + (5x + 7y)

What will be the linear model for the given data?Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option
So if we put the value x=1980 in the [tex]Y=0.213x-352[/tex] then
[tex]Y=0.213(1980)-352[/tex]

The houses in a row are numbered consecutively from 1 to 49. Show that there exists a value of x such that the sum of numbers of houses preceding the house numbered x is equal to sum of the number of houses following x.
Don't Spam
Answer:
Number of the houses as x =35
Step-by-step explanation:
The number of houses is 1, 2, 3, ..., 49
By observation, the numbers of houses are in an A.P.
Hence
First-term, a = 1
Common difference, d = 1
Let us assume that the number of xth house can be expressed as below:
We know that sum of n terms in an A.P. is given by the formula Sₙ = n/2 [2a + (n - 1) d]
Sum of number of houses preceding xth house = Sₓ ₋ ₁
Sₓ ₋ ₁ = (x - 1) / 2 [2a + ((x - 1) - 1)d]
= (x - 1) / 2 [2 × 1 + ( x - 2) × 1]
= (x - 1) / 2 [2 + x - 2]
= [x (x - 1)] / 2 ---------- (1)
By the given information we know that, sum of number of houses following xth house = S₄₉ - Sₓ
S₄₉ - Sₓ = 49 / 2 [2 × 1 + (49 - 1) × 1] - x / 2 [2 × 1 + (x - 1) × 1]
= 49 / 2 [2 + 48] - x / 2 (2 + x - 1)
= (49 / 2) × 50 - (x / 2) (x + 1)
= 1225 - [x (x + 1)] / 2 ---------- (2)
It is given that these sums are equal, that is equation (1) = equation(2)
x (x - 1) / 2 = 1225 - x (x + 1) / 2
x² / 2 - x / 2 = 1225 - x² / 2 - x / 2
On solving further we get,
x² = 1225
x = ± 35
As the number of houses cannot be a negative number, we consider the number of houses as x = 35
35 is the correct answer
Step-by-step explanation:
Given that the houses in a row are numbered consecutively from 1 to 49. We need to show that there exists a value of x such that the sum of numbers of houses preceding the house numbered x is equal to sum of the number of houses following x. Making it more simple for you; sum of (1, 2, 3, 4.... upto x - 1) is equal to sum of (x + 1), (x + 2), (x + 3).... upto 49.
→ Sum of (x - 1) terms = Sum of (49 - x) terms
"x" is the number of houses required. The sum of houses are in AP where the value of a is 1 and d is also 1; where 'a' is first term and 'd' is common difference. We know that sum of nth term of an AP is given by: T(n) = a + (n - 1)d and upto nth term by S(n) = n/2 (2a + (n - 1)d). And also by T(n) = S(n) - S(n - 1).
As per given problem:
→ (x - 1)/2 (Sum of first and last term) = (49 - x)/2 (Sum of first and last term)
→ (x - 1)(Sum of first and last term) = (49 - x) (Sum of first and last term)
Where first term and last term in LHS is 1 and (x - 1) & in RHS is (x + 1) and 49. Substitute them.
→ (x - 1) (1 + (x - 1)) = (49 - x) ((x + 1) + 49)
→ (x - 1) (1 + x - 1) = (49 - x) (x + 1 + 49)
→ (x - 1) (x) = (49 - x) (x + 50)
→ x² - x = 49x + 2450 - x² - 50x
On solving we get,
→ 2x² - 2450 = 0
→ 2x² = 2450
→ x² = 1225
→ x = ± 35
The number of houses is a positive integer. So negative value neglected. We left with x = 35. Therefore, the value of x is 35.

Step-by-step explanation:
x + 61 = 90
Because of the right angle symbol
x = 90 - 61
x = 29°
x + y = 90
Because vertically opposite angles are equal
29 + y = 90
y = 90 - 29
y = 61°

B. 339.12 cubic cm
C. 3052.08 cubic cm
D. 1017.36 cubic cm
Answer:
3052 cm^3 (Answer C)
Step-by-step explanation:
The formula for the circumference of a circle of radius r is C = 2(pi)(r). We know that C = 56.52 cm and want to find the model's radius:
C 56.52 cm
Solving for r, we get ---------- so that in this case r = ------------------ or
2(pi) 6.28
r = 9 cm.
The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r^3), which here comes out to:
V = (4/3)(3.14)(9 cm)^3 = 3052 cm^3 (Answer C)

(b) II only
(c) I and II
(d) I and III
(e) I, II, and III
The statements about the power that is true include E. I, II, and III.
What is power?Power simply means the amount of energy that is transferred or converted per unit time.
It should be noted that an increase in sample size increases power and a test with a higher power is more likely to reject false null hypothesis.
Increasing sample size will make the hypothesis test more sensitive and thus more likely to reject the null hypothesis. Thus, it increases the power of the test.
