Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8 ?
Minchanka [31]

Answer:

2.3 × 10^{-4} is 20,000 times greater than 1.15 × 10^{-8}

Step-by-step explanation:

Given as :

The first number= x = 2.3 × 10^{-4}

The second number= y = 1.15 × 10^{-8}

Let The first number is z times greater than second number

i.e x = z × y

Or, z = \dfrac{x}{y}

Or, z = \dfrac{2.3\times 10^{-4}}{1.15\times 10^{-8}}

Or, z = 2 × 10^{4}

∴  z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 × 10^{-4} is 20,000 times greater than 1.15 × 10^{-8} . Answer

Given ∆QRS≅∆TUV, QS=4v+3, and TV=7v-9, find the length of QS and TV.?
Anon25 [30]
If we are supposed to assume that QS=TV

4v+3=7v-9
minus 4v both sides
3=3v-9
add 9
12=3v
divide 3
4=v
v=4

sub back

4v+3=QS=TV
4(4)+3=QS=TV
16+3=QS
19=QS=TV

then answer is C
