Answer:

Two expressions are said to be equivalent , if after assigning the value of variable by some constant value the , the numerical value of original expression and Equivalent expression are same.

Original Expression=6g-18 h

Equivalent Expression

=2 × 3×g -2×3×3 h

=2×3×(g-3h)

=6(g-3h)

A baker purchases flour each week from a wholesale warehouse. The chart shows the quantities and prices available this week. If

scZoUnD [109]

The chart showing the quantities and prices is;

Best Deal 1

Quantity of Flour Price

3 pounds $5.25

5 pounds $9.75

7 pounds $12.60

10 pounds $14.20

12 pounds $18.24

Answer:

difference between last weeks best deal = $0.3

Step-by-step explanation:

Let's calculate the unit price for each of the quantities in the chart.

For quantity of 3 pounds;

We have; unit price = 5.25/3 = $1.75

For 5 pounds;. Unit price = 9.75/5 = $1.95

For 7 pounds; unit price = 12.6/7 = $1.8

For 10 pounds; unit price = 14.2/10 = $1.42

For 12 pounds; unit price = 18.24/14 = $1.3

Thus, last weeks best deal is the lowest = $1.3

Thus; difference between last weeks best deal is given as;

= this weeks best deal - last weeks best deal

This gives;

$1.6 - $1.3 = $0.3

A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 42 states. What is the probability that sh

Andrews [41]

Answer:

P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷

Step-by-step explanation:

Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:

$n=\frac{42!}{(42-4)!}\\n=42*41*40*39\\n=2,686,320\ ways$

Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷

If sinx=1/5 and x terminates in the first quadrant, determine cos 2x.

LenaWriter [7]

Hey there! I'm happy to help!

Let's think of this angle being put inside of a unit circle (a circle with a radius of one). This angle is going to stay inside the first quadrant, so all of its trigonometric ratios will be positive.

We are given that the sin of x is 1/5. To get the x by itself, we can just find the inverse sine of both sides to isolate the x.

x=sin $^-1$ (1/5)

x≈ 11.536959

2x≈ 23.073918

Now, we just cosine this value.

cos2x≈ 0.92

I hope that this helps! Have a wonderful day!
