Answer:
a: 9
b: 27
Step-by-step explanation:
Let's define
P = amount of model cars that Peter has
J =amount of model cars that Jade has
A = amount of model cars that Andre has
a: We need to find out how many model cars does Peter have, i.e. we need to find out P.
We know that Andre has 36 model cars and he has 4 times as many model cars as Peter. If we write that as an equation, we have
A = 4*P = 36
Now we just have to divide by 4:
4*P/4 = 36/4
P = 9
Peter has 9 model cars.
b: Now we need to find out how many model cars does Jade have, i.e. we need to find out J.
We will resolve it as in part a:
Peter has 9 model cars and he has one-third as many model cars as Jade, that is
P = 1/3*J = 9
We multiply by 3 and we have:
1/3*J*3 = 9*3
J = 27
Jade has 27 model cars.
(2^8 *3^-5* 6^0)^-2 * ((3^-2)/(2^3))^4 * 2^28
anything to the 0 power is 1
(2^8 *3^-5* 1)^-2 * ((3^-2)/(2^3))^4 * 2^28
using the power of power property to take the power inside
(2^(8*-2) *3^(-5* -2) * (3^-2*4)/(2^3*4) * 2^28
simplify
2^ -16 * 3^10 * 3^-8 /2*12 * 2^28
get rid of the division by making the exponent negative
2^-16 * 3^10 * 3^-8 *2*-12 * 2^28
combine exponents with like bases
2^(-16-12+28) * 3^(10-8)
2^(0) *3^2
anything to the 0 power is 1
1*9
9
You can also just multiply by the decimal equivalent.
12*.35=4.2
35% of 12 is 4.2
Hope this helps!
Answer:
4.2
Step-by-step explanation:
Find 35% of 12.
To find 35% of 12, you can use the method you demonstrated above by solve
35% = 35/100
of 12 = multiplication.
35/100 × 12
0.35 × 12
= 4.2
OR
35 × 12/100
420/100
= 4.2
Hope this helps!
