if $20.00 is for 12.25kg of peas ...what weight of peas can i get for $4.00​

Answers


2.45kg

First you calculate the price per kg as follows:

If it’s $20 for 12.25 kg, the price per kg is $20/12.25=$1.63 per kg


If you have $4, you can figure out what weight you can get by taking $4/the price per kg, so $4/$1.63, which is 2.45 kg.

Find the quotient and remainder 975 divided by 17

Answers

Answer:

975 / 17 = 57 R 6

Step-by-step explanation:

To get a good starting point, let's round these values to "nicer" numbers. 975 is close to 1000, and 17 is close to 20, and 1000 / 20 = 50, so let's start by looking at 17 x 50 and go from there.

There are a few ways to calculate 17 x 50, but here I'm gonna go off what we already know: 20 x 50 = 1000, and 20 - 3 = 17, so 17 x 50 = 20 x 50 - 3 x 50, or 1000 - 150, which is 850. How many more 17s can we fit from 850 to 975? Well, the difference between the two numbers is 125, so finding the quotient of 125 and 17 should be enough: 17 fits into 125 7 times, with 6 remaining.

Altogether then, 975 / 17 has a quotient of 50 + 7 = 57, and a remainder of 6.

X^2+9x+7=y standard to vertex form

Answers

Answer:

y = (x + 4.5)² - 13.25

Step-by-step explanation:

y = x² + 9x + 7

We need to get a perfectly squared binomial as part of the right side.

Take the '9x' term, divide it in half, square it, add and also subtract it on the right side, as shown below. That would be (4.5)² = 20.25 added and subtracted.

y = x² + 9x        + 7

y = x² + 9x + 20.25       + 7 - 20.25

y = (x² + 9x + 20.25)  - 13.25

y = (x + 4.5)² - 13.25

y = (x + 4.5)² - 13.25

Vertex Form is y = a(x-h)² + k, where the parabola vertex is (h, k)

So if you wrote this as y = 1(x - [-4.5] )² + (-13.25), we would see that a = 1, and h = -4.5 and k = -13.25.

Vertex = (-4.5, -13.25)

I verified on a graphing calculator that this is indeed the vertex of the parabola.
