14) A solid metallic block measures 1.5m long, 0.4m wide and 0.25m high. The solid is made of

GREYUIT [131]

Answer:

<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>

Step-by-step explanation:

To find the mass in kg we must first convert the density from g/cm³ to kg/m³

That's 7.5 g/cm³ = 7500kg/m³

Density = mass / volume

Volume of block = 1.5 × 0.4 × 0.25

= 0.15m³

mass = Density × volume

= 7500 × 0.15

Hope this helps you

Which of the following represents a geometric series (remember what a series is as opposed to a sequence)?

juin [17]

Answer:

4 + 12 + 36 + ...

Step-by-step explanation:

4, 12, 36, ... is a geometric sequence, it has a common ratio of $r=\frac{36}{12}=\frac{12}{4}=3$

When we add the terms of a geometric sequence we get a geometric series.

4+12+36+ ... is a geometric series, it has a common ratio of $r=\frac{36}{12}=\frac{12}{4}=3$

4 + 12 + 20 + ... is not a geometric series because it has no common ratio

$\frac{20}{12}\ne \frac{12}{4}$

The second choice is correct

Divide 33 photos into two groups so the ratio is 4 to 7

Advocard [28]

4 to 7
or
4+7= 12
4x+7x=33
x=3
so,
(4×3)+(7×3)=33
12+21=33
or
12 and 21.
hope it helped
