What is the volume of the following rectangular prism?​

Answer:

99

Step-by-step explanation:

Through some clever algebra, we can combine our first two equations using the fact that

[tex](a+b)^2=a^2+2ab+b^2[/tex]

We have the a² and the b² in the equation [tex]a^2+b^2=81[/tex], and we almost have a 2ab in the equation [tex]ab=9[/tex]. To get that 2ab, we can simply double both sides of the first equation to get [tex]2ab=18[/tex]. From there, we'll add the first two equations together, giving us the summed equation

[tex]a^2+b^2+2ab=81+18\\a^2+2ab+b^2=99[/tex]

And since [tex](a+b)^2=a^2+2ab+b^2[/tex], we can equivalently say that

[tex](a+b)^2=99[/tex]

b 5s

c 2r -76 this can be the answer

Answer: A) 3p , B) 5s , C) -6r+8t-76

Step-by-step explanation:

A ) 4p + 2p – 3p

combine like terms :-

(4p+2p+-3p)

(4p+2p+-3p) = 3p

= 3p

B ) 9s- 5s + 2s-S

combine like terms :-

( 9s-5s+2s+-s)

( 9s-5s+2s+-s) = 5s

C )  8t + 3r - 76 - 9r​

combine like terms :-

(3r+-9r)+(8t)+(-76)

= - 6r+8t+-76

Answer:

The Price of socks is

Explanation:

Given -

Discount 25%

Price of shirt before discount  

=

24

Amount spent on both shirt and socks after applying discount  

=

24

Assume the price of socks  

=

$

x

Then Shirt + Socks before discount =

(

24

+

x

)

After discount one has to pay 75% of the article.

Then -

How to verify your answer -

One way

Price of shirt =$24

Price of socks =$8

Total =$32

Discount =25%

Discount for $32 is

8

Amount one has to pay after discount  

=

Another way is -

Discount 25%

It means after discount it is enough if he pays 75% of the price.

In our case - Actual price is

Answer:

[tex]\Huge\boxed{76}[/tex]

Step-by-step explanation:

Hello There!

The first thing we want to do is find the proportional relationship between to two triangles

The smaller triangles longest side is 18

Given the longest side of the similar triangle we can divide the longest side of the preimage by the longest side of the similar triangle

So the proportional relationship would be

36/18 or 2

Our next step is to find the the sides of the similar triangle

To do so we multiply the sides of the preimage by 2 (because 2 is the proportional relationship between the two triangles)

12x2=24

8x2=16

and we already know that the longest side measures 36

Now we can find the perimeter by adding all of the side lengths

36+24+16 = 76

So we can conclude that the perimeter of the dilated image is 76

The perimeter of the dilated triangle is 81.

Answer:

39/16 or 2 7/16 miles

Step-by-step explanation:

find the common denominator between all fractions (16).

1/2 = 8/16

3/4 = 12/16

8 + 11 + 8 + 12 = 39

Therefore, Joey walked 39/16 or 2 7/16 miles in total

Answer:

Step-by-step explanation:

S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.

If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle)  the hypotenuse of the two triangles will be congruent.

Now, as hypotenuse  and  one leg are congruent in both triangles, we can apply RHS congruent

Answer:

lateral area = 180π in²

Step-by-step explanation:

The lateral area is the surface of the cone only.

perimeter of base = 12 x 2 = 24π in

Surface Area = 1/2 perimeter x slant height

SA = 1/2 x 24π x 15 = 180π in²

Answer

15 plates, 12 napkins and 10 cups

Step-by-step explanation:

To find the least amount, you have to find the lcm of all three numbers. In this case the lcm of 8,10, and 12 is 120. Afterwards you need to divied 120 by all numbers. So 120 divided by 8 is 15, so 15 plates. 120 divided by 10 is 12, so 12 napkins and finally 120 divided by 12 is 10, so 10 cups

The least number of packages of plates, napkins, and cups Maia has to buy so that she has the same number of each Item for her birthday party is 15, 12, and 10, respectively.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given that paper plates come in packages of eight, napkins come in packages of 10, and paper cups come in packages of 12. Therefore, to find the least number of packages of plates napkins and cups Maria has to buy so that she has the same number of each Item for her birthday party, we need to take the LCM of the following.

LCM of 8, 10, and 12 = 120

Now, the number of packages,

[tex]\text{Number of paper plate packs} = \dfrac{120}{8}=15[/tex]

[tex]\text{Number of napkins pack} = \dfrac{120}{10}=12[/tex]

[tex]\text{Number of paper cups pack} = \dfrac{120}{12}=10[/tex]

Hence, the least number of packages of plates, napkins, and cups Maia has to buy so that she has the same number of each Item for her birthday party is 15, 12, and 10, respectively.
