A bricklayer needs to order 6300kg of building sand
luda_lava [24]

Answer:

9\times 10^7\ \text{grains of sand}

Step-by-step explanation:

Given that,

A bricklayer needs to order 6300kg of building sand.

1 grain of this sand weighs 7\times 10^{-5}\ kg.

We need to find how many grains of sand are there in 6300 kg.

It can be just calculated as follows :

1 grain of sand =  7\times 10^{-5}\ kg

6300\ kg=\dfrac{6300}{7\times 10^{-5}}\\\\=9\times 10^7\ \text{grains of sand}

or

= 90000000  grans of sand

So, 6300 kg is equal to 9\times 10^7\ \text{grains of sand}.

Find the measure of angle ABD
Brut [27]

Answer:

137

Step-by-step explanation:

The sum of all three angles; <ABC, <ABD, and <CBD is equal to 360

now we know <ABC = 118 and

the measure of central angle <CBD is equal to measure of the arc it sees so it's = 105

we are asked to find the  m<ABD

118 + 105 + <ABD = 360 add like terms

223 + <ABD = 360 subtract 223 from both sides

m<ABD = 137
