Answer:
$24, $30, $36
Step-by-step explanation:
First we need to find the unit rate.
1. 18÷3 = 6
So that means one taco costs $6.
6*4 = 24
6*5 = 30
6*6 = 36
Answer:
cylinder has greatest volume
Step-by-step explanation:
solution
given,
radius of cylinder(r)=6cm
height of cylinder (h)=6cm
we know,
volume of cylinder=πr^2h
=22÷7×6×6×6
=4752÷7
=678.857cm^3
radius of cone(r)=6cm
height of cone(h)=12cm
we know,
volume of cone=1÷3πr^3
= 1÷3×22÷7×6×6×6
= 4752÷21
=226.2857cm^3
as a result,cylinder has greatest volume
Answer:
option c
Step-by-step explanation:
<em>Step 1: Multiply each number in matrix A by -4</em>
( -4x-4 -4x-4 1x-4 )
( 1x-4 4x-4 7x-4)
( 2x-4 3x-4 3x-4)
( 16 16 -4 )
( -4 -16 -28)
( -8 -12 -12)
<em>Step 2: Multiply each number in matrix B by 8</em>
( 2x8 9x8 -9x8 )
( 8x8 8x8 -2x8 )
( 4x8 10x8 1x8 )
( 16 72 -72 )
( 64 64 -16 )
(32 80 8 )
<em>Step 3: Form the matrix of -4A + 8B by adding the correspondent numbers in the matrix.</em>
( 16+16 16+72 -4-72 )
( -4+64 -16+64 -28-16 )
( -8+32 -12+80 -12+8)
( 32 88 -76 )
( 60 48 -44)
( 24 68 -4 )
Therefore option c is correct.

Answer: 49
==============================================
Explanation:
HI is parallel to KL, so this means that the two triangles can be proven similar through the AA (angle angle) similarity theorem.
Consequently, that means we can set up the proportion below
JH/JK = HI/KL
noticed how the left slant sides JH and JK pair up together on one side; the horizontal sides HI and KL pair up on the other side. I have the larger triangle's side lengths as the numerator for each side
Plug in the given values. Solve for HI
JH/JK = HI/KL
35/15 = HI/21
7/3 = HI/21
21*7 = 3*HI
3*HI = 147
HI = 147/3
HI = 49
This means that 35/15 = HI/21 turns into 35/15 = 49/21
Note: to check the answer that the last equation mentioned is true, we can subtract the fraction 49/21 from both sides to end up with 35/15 - 49/21 = 0. If you type "35/15 - 49/21" into your calculator, you should get 0, which will help confirm we have the right answer.
