If 27^27+27^27+27^27=3^k What is k?

JulijaS [17]

Answer:

$\large{\boxed{k=82}}$

Step-by-step explanation:

$27^{27}+27^{27}+27^{27}=3^k$

$3 \cdot 27^{27}=3^k$

$3 \cdot (3^3)^{27}=3^k$

$3 \cdot 3^{81}=3^k$

$3^{82}=3^k \implies k=82$

Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees

Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)

A rectangular garden is to cover 468 square feet of area. If the width 8 feet less than the length find both dimensions, with th

melisa1 [442]

Length of garden is 26cm and width is 18cm.

Step-by-step explanation:

Given,

Area = 468 Square feet

Let l be the length and w be the width.

According to statement;

w = l - 8 Eqn 1

Area = w*l = 468 Eqn 2

Putting Eqn 1 in Eqn 2

$(l-8)*l=468\\l^2-8l=468\\l^2-8l-468=0$

Solving the equation by factorization;

$l^2+18l-26l-468=0\\l(l+18)-26(l+18)=0\\(l+18)(l-26)=0\\$

Either,

l+18=0 => l= -18

Or,

l-26=0 => l=26

As length cannot be negative, therefore,

l=26cm

w= $l-8=26-8\\$

w=18cm

Length of garden is 26cm and width is 18cm.

Samuel and Randi are placemat weavers. Samuel can weave 7 placemats in 8 hours. Randi can weave 5 placemats in 4 hours. How many

goblinko [34]

Answer: 85 placemats

Step-by-step explanation:

Let’s split it into three parts: how much Samuel can weave, how much Randi can weave, and how much they can weave in total

Part 1: Samuel

First, let’s figure out how much Samuel can weave!

First, we know that Samuel can weave 7 placemats in 8 hours (1 day). So, if he weaved placemats for 5 days, then:

= 7 x 5

= 35

Therefore, Samuel weaved 35 placemats in 5 days if he worked 8 hours each day.

Part 2: Randi

We know that Randi makes 5 placemats in 4 hours, which is half, a day. But lets figure out how many placemats he can make it a day.

All we have to do is multiply by two.

= 5 x 2

= 10

So, we now know that he can make 10 placemats in a day. Now, let’s see how many placemats he can make in five days.

= 10 x 5

= 50

Therefore, Randi weaved 50 placemats in 5 days if he worked 8 hours each day.

Part 3: Adding Them

Now, we have 35 placemats from Samuel and 50 placements from Randi. So, we have to add them.

= 35 + 50

= 85

Therefore, Randi and Samuel can make 85 placemats in 5 days together if they work 8 hours each day.
