Answer:
3.3 kg
Step-by-step explanation:
1 pound = 0.453592kilogram
so you just need to 7.3*0.453592= 3.3kilograms
Answer:
$28,455
Step-by-step explanation:
Change 15% into a decimal.
(15)(1/100)=0.15
***(1/100) because 15 part of the whole 100 percent/.
(189,700)(0.15)
=28455
Answer:
x=12
Step-by-step explanation:
1/2*x =1/2x
1/2*2 =1
you need to get the constants on one side so subtract 1 on all sides to get 6=1/2x, then divide by 1/2 on all sides to get x= 12
Answer:
y = 10
Step-by-step explanation:
based on the question if y varries directly as x
mathematically
y ∝ x
also, y varries inversly as z can be mathematically expressed as
y ∝ 1/z
combining the two expressions
y ∝ x ∝ 1/z
i. e
y = kx/z..... where k is the constant of proportionality
make k the subject of formulae
yz = kx
Divide both sides by x
k =yz/x
when y=100 , x = 5 z =10
k = 100 × 10/5
k = 200
to find y when x = 3 and z = 60
<h3>from the equation connecting x,y,z</h3>
k =yz/x
200 =60y/3
cross multiply
60y = 200 × 3
60y = 600
divide both sides by 60
y = 10
