solve the equation by using trial and error method 6 - x =2​

Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

The given equation is :

6 - x =2​

Put x = 1 and see LHS is equal to RHS or not.

So,

6-1 ≠ 2

Put x = 2 and see LHS is equal to RHS or not.

So,

6-2 ≠ 2

Put x = 3 and see LHS is equal to RHS or not.

So,

6-3 ≠ 2

Put x = 4 and see LHS is equal to RHS or not.

So,

6-4=2

2 = 2

So, the solution of the given equation is x = 4.

There are some red counters and some yellow counters in a bag in the ratio 1 : 5
There are 20 yellow counters in the bag.
Janet puts some more red counters into the bag.
The ratio of the number of red counters to the number of yellow counters is now 1 : 2
How many red counters does Janet put into the bag?

Answers

Answer:

Janet put 6 red counters into the bag

Step-by-step explanation:

There are 5 yellow counters for every 1 red counter. If there are 20 yellow counters in the bag then there are 4 red counters. (20/5). If the ratio becomes 1:2 this means there are 2 yellow counters for every 1 red counter. There are 20 yellow counters so there must be 10 red counters in the bag. (20/2). 10 - 4 = 6. Janet put 6 red counters into the bag. (Brainliest would be appreciated!)

1. Rita has 3 ¾ cups of potato chips to share with 6 friends. How many cups does EACH friend get

Answers

Answer:

Each friend will get 5/8 (excluding Rita)

Each person will get 15/28 (including Rita)

Step-by-step explanation:

You must simply divide 3 3/4 ÷ 6 (excluding Rita)

You must simply divide 3 3/4 ÷ 7 (including Rita)

5/8 cups

You divide 3 3/4 by 6 so

3.75/6 = 0.625

Then make that back into a fraction
0.625= 5/8

There’s a different way where you keep it a fraction but it takes longer so here you go I hope it helps some.

What are the domain restrictions of q^2-3q-4/q^2-7q-8

Answers

Fourth option.

We cannot divide by zero, so the denominator cannot equal zero.

0 = q^2 - 7q - 8
0 = (q - 8) * (q + 1)

0 = q - 8 when q = 8
0 = q + 1 when q = -1

So q cannot equal 8 or -1

A loan of $20,000 is made at 7% interest, compounded annually. After how many years will the amount due reach $41,000 or more?​

Answers

Answer:

Step-by-step explanation:

11 years

Using the compound interest formula. :

Final amount, A = 41000 or more

Rate, r = 7% = 0.07

Loan amount, P = 20,000

Number of compounding times per period = 1

A = P(1 + r/n)^nt

41000 = 20000(1 + 0.07)^t

41000/20000 = 1.07^t

2.05 = 1.07^t

t = log(2.05) / log(1.07)

t = 10.609727

t = 11 years

It has been estimated that a certain stream can support 85,000 fish if it is pollution-free. It has further been estimated that for each ton of pollutants in the stream, 1700 fewer fish can be supported. Assuming the relationship is linear, write the equation that gives the population of fish p in terms of the tons of pollutants x.

Answers

Answer:

[tex]p = 85000 - 1700x[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Fish = 85000[/tex]

[tex]Rate = 1700[/tex]

Required

Determine the equation

For 1 ton, there is a reduction of 1700 fishes

This implies that:

For x tons, there will be a reduction of 1700x fishes

So, the function is:

[tex]p = Initial\ Fishes - Rate * x[/tex]

We used minus because the number of fishes reduced.

So, we have:

[tex]p = 85000 - 1700*x[/tex]

[tex]p = 85000 - 1700x[/tex]

Hence, the function is: [tex]p = 85000 - 1700x[/tex]

The length of a rectangle is 2ft longer than its width.
If the perimeter of the rectangle is 40ft , find its area.

Answers

The area is 96ft.

We know that the perimeter includes four sides. Divide the 40 by 4. You will get 10. Four sides of ten would get you a perimeter of 40. Now take two tens, one for the length and the width. Add 2 to one side and subtract 2 from the other. This will get a length of 12 and a width of 8. Than multiply the 12 and 8 to get the area. You will get 96.

Tasha is packing gift bags that include

the same items. She has 72 glow sticks,

36 markers, and 24 bottles of bubbles.

Tasha believes that she can pack no

more than 6 bags using all of her

supplies. Do you agree with Tasha? Explain.

Answers

Answer:

No, I do not.

She can pack up to 12 bags

Step-by-step explanation:

Given

[tex]Glow\ sticks = 72[/tex]

[tex]Markers = 36[/tex]

[tex]Bubbles = 24[/tex]

Required

Is Tasha correct?

The maximum number of bags she can pack is determined by the greatest common factors (GCF) of the items.

i.e. GCF of 72, 36 and 24.

This is calculated as:

[tex]24 = 2*2*2*3[/tex]

[tex]36 = 2 * 2 *3*3[/tex]

[tex]72 = 2 * 2 * 2 *3*3[/tex]

Multiply all common factors:

[tex]GCF = 2 * 2 * 3[/tex]

[tex]GCF = 12[/tex]

The GCF is 12.

This implies that she can pack up to 12 bags

the nearest tenth, what is the height of the pole?
65°
21 ft.
Plz help

Answers

Answer:

h = 452.5 ft

Step-by-step explanation:

Angle of elevation from P to top of the pole = 65°

Horizontal distance between the pole and point P = 21 ft

By Applying tan rule in the given triangle ABP,

tan(∠APB) = [tex]\frac{AB}{PB}[/tex]

tan(65°) = [tex]\frac{h}{21}[/tex]

h = 21[tan(65°)]

h = 452.491

h ≈ 452.5 ft

Therefore, height of the pole is 452.5 ft.

The music first entered the American consciousness on a nationallevel when Scott Joplin published "Maple Leaf Rag" in 1899. It was the first instrumental plece to sell overa million coples. Scott Joplin's work saw a revival during the 1970s with the success of the movie The Sting.Joplin did not invent ragtime, however. The music's origins can be traced to the African Americanmusic of the late nineteenth century. Ragtime incorporated the rhythms and beats of African Americanmusic with the march music of the era, which had its origins in European classical. Once the dance musicof ragtime became popular, it didn't take long to spread from the Southern hubs of New Orleans and St.Louls to the metropolitan centers of New York and Chicago.By the 1920s, the ragtime craze was fading. It continued to be performed and recorded, but it wasbeing replaced with new kinds of music. However, it had a lasting influence, evident in the early Jazzstyles that emerged/ Some might argue that ragtime is the starting point for all popular music in America.Before ragtime, American music lacked individuality and character. The advent of this music instilled anew rhythm and style into popular American music that continues to this day.8. Which of the following conclusions can be drawn from the passage?A. Ragtime music had an influence on European music.B. Modern pop music is based on European styles.C. Scott Joplin is the founder of American jazz.D. Modern music can be traced as a progression of style.
