Answer:

volume of the square pyramid is:

V = s2h/3

where s=side length and h= height

for square pyramid A

h(a)= 8in and s(a)=12in

volume of square pyramid for A =

V(a)=s2(a) h(a)/3

V(a)=122 . 8/3 \implies⟹ 144 . 8/3 \implies⟹ 1152/3 \implies⟹ 384 in3

for square pyramid B

h(b)=24in and s(b)=36in

volume of square pyramid for B =

V(b)=s2(b) h(b)/3

V(b)=362 . 24/3 \implies⟹ 1296 . 24/3 \implies⟹ 31104/3 \implies⟹ 10368 in3

We want to know how many times the volume of pyramid B is bigger than pyramid A :

= V(b)/V(a)

=10368/384

= 27 times

Step-by-step explanation:

hope this helps if not let me know have a great day

Add the mixed number fractions. Simplify, if possible.
Vladimir79 [104]

Answer:

8 4/15

Step-by-step explanation:

Rewriting our equation with parts separated

= 5 + 2/3 + 2 + 3/5

Solving the whole number parts

5 + 2 = 7

Solving the fraction parts

2/3 + 3/5 = ?

Find the LCD of 2/3 and 3/5 and rewrite to solve with the equivalent fractions.

LCD = 15

10/15 + 9/15 = 19/15

Simplifying the fraction part, 19/15,

19/15 = 1 4/15

Combining the whole and fraction parts

7 + 1 + 4/15 = 8 4/15

M³×n=189 Find m and n
Flura [38]

Answer:

m=3, n = 7

Step-by-step explanation:

Assuming m and n are integers, the following are the possible values of m and n

Let m = 1, then m³ = 1 and n= 189

If m = 2 we get 8n = 189 and 189/8 is not an integer so m ≠ 2

If m = 3, we get 27n = 189 and n = 189/27 = 7

Any higher integer values of m will not result in n being an integer and I am assuming m > 1 so the correct answer is m=3, n = 7

Need some help with this question!
Veronika [31]
1. solve for x in first to just find nterms of y

x=12-y
sub that for x in other one
first divide that one by 2 to make it easier
2x-y=18
2(12-y)-y=18
24-2y-y=18
24-3y=18
minus 24 both sides
-3y=-6
divide -3
y=2

D is answer




2.
find intersection of x+y=5 and -2x+3y=6
or easiers, just test the intersections
wait, they all intersect in the same place
this is super easy
pick ANY point that is in that reigon and see if it is true

A, if we pick lets say (5,5)
that is false for x+y<5
not A

B
pick (10,0)
false for first one
not B

C
pick (0,0)
true for first
false for 2nd
not C


D. pick (-10,0)
true for first
true for 2nd


answer is D


answer is D for both questions

Which of the following is the product of the rational expression shown below
wolverine [178]

Option C: \frac{x^{2}-9}{x^{2}-4} is the product of the rational expression.

Explanation:

The given rational expression is \frac{x+3}{x+2} \cdot \frac{x-3}{x-2}

We need to determine the product of the rational expression.

<u>Product of the rational expression:</u>

Let us multiply the rational expression to determine the product of the rational expression.

Thus, we have;

\frac{(x+3)(x-3)}{(x+2)(x-2)}

Let us use the identity (a+b)(a-b)=a^2-b^2 in the above expression.

Thus, we get;

\frac{x^{2} -3^2}{x^{2} -2^2}

Simplifying the terms, we get;

\frac{x^{2}-9}{x^{2}-4}

Thus, the product of the rational expression is \frac{x^{2}-9}{x^{2}-4}

Hence, Option C is the correct answer.
