2 boxes of eggs = 1.30 × 2 = 2.60

1 bottle of juice = 2.60

he payed 10 and got 0.90 so he payed 9.10

Is the following statement true or false?

andrew-mc [135]

True because you can put it in any order without affecting it. Example : 5 • 7 = 7 • 5. Either way they still equal 35, therefore the answer will be true.

Hope this helps :)

Answer:

Total number of unemployment in 2018 = 3,276,420

Step-by-step explanation:

Given:

Total number of unemployment in 2017 = 3,766,000

Decreased in unemployment = 13%

Find:

Total number of unemployment in 2018

Computation:

Total number of unemployment in 2018 = Total number of unemployment in 2017 - Decreased in unemployment

Total number of unemployment in 2018 = 3,766,000 - 13%

Total number of unemployment in 2018 = 3,276,420

Solve the equation log4(x + 20) = 3

salantis [7]

Answer:

Step-by-step explanation:

I don not understand what is for 4 here. So there are 2 cases:

Case 1: If you mean: log[4(x+20)]= 3

We know 3 = log(10^3)= log(1000)

So we have log[4(x+20)]= log(1000)

so 4(x+20)= 1000

and x+20 = 1000/4

x+20 = 250 and finally x= 250-20, x=230

The solution is 230.

Case 2; If you mean that 4 is the base of logarithm.

$log_{4}(x+20)= 3$

and we know that $3=log_{4}(3^{4} )= log_{4}(81)$

So we have $log_{4}(x+20)= log_{4}(81)$

and x+20 = 81

or x= 81-20

x=61

The answer is 61.

Hope that useful for you, both cases.

Which set of points is not coplanar?

spin [16.1K]

we know that

Coplanar points are three or more points which lie in the same plane. Remember that a plane is a flat surface which extends without end in all directions. Any three points in 3-dimensional space determine a plane.

case a) points A, B, E

Any group of three points determines a plane

The points A,B,E are coplanar

case b) points A, B,C,E

The four points do not belong to the same plane

The points A,B,C,E are not coplanar

case c) points B, C, D

Any group of three points determines a plane

The points B, C, D are coplanar

case d) points A,B, C, D

The base of the pyramid is a flat surface, the four points lie in the same plane

The points A,B, C, D are coplanar

therefore

the answer is the option

points A, B, C, E are not coplanar
