Answer:

d = -4.7

Step-by-step explanation:

d + 0.7 = -4

subtract 0.7 from both sides

d + 0.7 = -4

- 0.7 -0.7

d = -4.7

Ben needs to buy orange juice. He can buy 64 fl oz at the grocery store for $2.00, or he can buy 256 fl oz at the wholesale club

crimeas [40]

Unit price so compare
2 gets 64 or 7.50 get 256
grocery store 2:64=1:32=32 oz per $1
wholesale club 7.5:256=1:34.133=34.133 oz per $1
wholesale club gets you more oz of juice for the same price

A: 32 oz per $1 or $0.031 per 1 oz
B: 34.133 oz per $1 or $0.029 per 1 oz
C: best deal is at wholesale club

Write 0.0000002711 in scientific notation. (Use 2 numbers after the decimal point.)

Lesechka [4]

Answer:

$Number = 2.71 * 10^{-7}$

Step-by-step explanation:

Given

$Number = 0.0000002711$

Required

Write, using scientific notation

The scientific notation is written in the form:

$Form = a * 10^n$ Where n is an integer and $1 \leq a \leq 10$

To start with; Represent the given number as fraction

$Number = \frac{2711}{10000000000}$

Represent the denominator as an exponent

$Number = \frac{2711}{10^{10}}$

This can be rewritten in form of:

$Number = 2711 * 10^{-10}$

Remember that: $Form = a * 10^n$ Where n is an integer and $1 \leq a \leq 10$

This implies that; we need to adjust 2711 to a number between 1 and 10;

This gives:

$Number = 2.711 * 1000 * 10^{-10}$

Write 1000 as an exponent

$Number = 2.711 * 10^3 * 10^{-10}$

Apply law of indices

$Number = 2.711 * 10^{3-10}$

$Number = 2.711 * 10^{-7}$

The question requires 2 numbers after the decimal point;

So, 2.711 will be approximated to 2.71

$Number = 2.71 * 10^{-7}$

Hence;

$0.0000002711$ is equivalent to $2.71 * 10^{-7}$

A line segment has one endpoint of A (-3,2) and a slope of (-3/5). Find coordinates for B

bekas [8.4K]

Answer:

Step-by-step explanation:

This is a very interesting problem. We are given the slope and one point, which makes this funner than normal ;)

Filling in the slope formula with what we are given:

$-\frac{3}{5}=\frac{y-2}{x-(-3)}$ which simplifies to

$-\frac{3}{5}=\frac{y-2}{x+3}$

Since slope is rise over run, the rise number is -3; the run number is 5. That means that the equation to find the y coordinate comes from -3 = y - 2; the equation to find the x coordinate comes from 5 = x + 3 (keep in mind that you could have made the x coordinate the negative one; it doesn't matter. You will get the same answer regardless...promise).

Solving for y:

-3 = y - 2 and

y = -1

Solving for x:

5 = x + 3 and

x = 2

Let's check those coordinates in the slope formula and see if our slope is in fact -3/5:

$m=\frac{-1-2}{2-(-3)}=-\frac{3}{5}$ so we're all good!

The coordinates of B are (2, -1)
