Step-by-step explanation:

a(n) = a +(n-1)d

a=-5

d=5

a(n) = -5 +(n-1)5

=-5+5n-5

=5n-10

a(50) = -5 +(50-1)5

= 240

a bricklayer needs to order 6300kg of building sand.one grain of this sand weighs 7x10^-5. how many grains of sand are there in

gavmur [86]

Answer:

44.1 x 10^-2

Step-by-step explanation:

Since one grain

= 7 x 10^-5

6300kg = 7 x 10^-5 x 6300

Put 6300 in standard form

7 x 10^-5 x 6.3 x 10^3

Multiply the whole numbers and add the exponents

7 x 6.3 x 10^-5 + 3

44.1 x 10^-2

There are 44.1 x 10^-2 grains of sand in 6300kg

If each acute angle of a parallelogram measures 59 degrees, then what is the masure of each obtuse angle?

xenn [34]

A parallelogram has to have a total of 360 degrees in angles, so we take 59 x 2 to get 118, we then subtract 118 from 360, 360 - 118 = 242, we then divide by two because a parallelogram has 2 obtuse angles, giving us an answer of 121 degrees. Hope this helps
