Steven’s mother asked him to buy 750 grams of sugar. At the supermarket, he finds that the sugar packages give the weight in kil
9966 [12]
1, 000 grams = 1 kg
(divide both sides by 1, 000)
1 gram = 1/1, 000 kg
750 grams = 750 x (1/1000) kg = 0.75 kg

Therefore, Steven needs to buy 0.75 kg of sugar!

hope this helps! let me know if you need help with anything else! :)

What is the area of this rectangle? Provide supportive evidence so I can learn better about this. I’m having troubles.
Katyanochek1 [597]

Answer:

the answer is 15x^8 y^3

Step-by-step explanation:

the area of a rectangle is length times width right? this means you have to multiply the values that represent the length and width. in this case those values would be 5x^6 y^2 and 3x^2 y

step 1. set up your problem

it should look like this:

(5x^6 y^2)(3x^2 y)

step 2. multiply the values with corresponding variables

first, x values

(5x^6)(3x^2)

5×3=15 and x^6 × x^2=x^8 when multiplying exponents you add the powers the numbers are raised to. in this case 6+2=8

you should end up with 15x^8

next, y values

y^2 + y

remember what i said about multiplying exponents? you just add the power the variables are raised to. in this case, 2 and 1. when their is no exponent we just add a 1. so, 2+1=3

you end up with y^3

lastly, combine

15x^8 + y^3 = 15x^8y^3

An=an−1−4 a1=15 to explicit formula
USPshnik [31]

Answer:

a_n=3n-12

Step-by-step explanation:

We are given the recursive formula:

a_n=a_{n-1}-4, a_1=15

This is the recursive formula for an arithmetic sequence.

The explicit formula for an arithmetic sequence is given by:

a_n=a_1 + d({n-1} )

Where d=3 is the common difference.

We plug in this values to get:

a_n=15 + 3({n-1} )

We now expand and simplify to get:

a_n=15 + 3n-3

We simplify to obtain:

a_n= 3n-12
