Answer:
(-5, 0)
Step-by-step explanation:
f(x) = (x - 1)(x2 + x - 20) = 0
x - 1 = 0
x = 1
x^2 + x - 20 = (x + 5)(x - 4)
x + 5 = 0; x - 4 = 0
x = -5; x = 4
Answer: (-5, 0)

John is collecting orange and green marbles in a bag. The ratio of orange marbles to green marbles is 6 to 4. If he has a total of 200 marbles in the bag, how many green marbles will there be? pls help and answer soon!
Answer:
120:80
120 orange
80 green
The number of orange marbles to green marbles will be 120 and 80 respectively.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that John is collecting orange and green marbles in a bag. The ratio of orange marbles to green marbles is 6 to 4. If he has a total of 200 marbles in the bag.
The number of bags will be calculated as:-
6x + 4x = 200
10x = 200
x = 20
Orange = 6x = 6 x 20 = 120
Green = 4x = 4 x 20 = 80

Round 46.832 to the nearest tenth
Answer:
46.8
Step-by-step explanation:
The reason for this is because if it is 5 or more round it up. if it is 4 or less let it rest. The answer 46.832 would hence round to 46.8 since the 8 in 46.832 is the tenths place.

Find the degree measure of each angle in tbr triangle
Answer: ∠p = 85; ∠Q = 72; ∠R = 23
have: m∠P + m∠Q + m∠R = 180°
=> 4x - 7 + 3x + 3 + x = 180°
⇔ 8x - 4 = 180
⇔ x = (180 + 4)/8
⇔ x = 23
=> m∠P = 4.23 - 7 = 85°
m∠R = 23°
m∠Q = 3.23 + 3 = 72°

In 2000, the population of Snowy Egrets went from 5,000 individuals to 15,000 individuals. What is the growth rate over those 4 years?
Answer:
[tex]x=\sqrt[4]{3}-1[/tex] or [tex]x=0.316[/tex]
Step-by-step explanation:
To write this equation you would need to use this equation for growth.
Final amount=initial amount (1+growth rate)^time
We have the final amount, 15,000, the initial amount, 5,000, and the time, 4 years. Now we have to plug in the values. We can write the growth rate as x.
[tex]15,000=5000(1+x)^4[/tex]
Now start by dividing both sides by 5000.
[tex]\frac{15000}{5000} =(1+x)^4[/tex]
[tex]3=(1+x)^4[/tex]
Now you can find the fourth root of both sides to get rid of the exponent.
[tex]\sqrt[4]{3} =1+x[/tex]
Finally, subtract 1 from both sides.
[tex]x=\sqrt[4]{3}-1[/tex]
And, if allowed, you can use a calculator to find the value in decimal form which would be:
[tex]x=0.316[/tex]

x=11 and the measure for angle B is 80
Step-by-step explanation:
First you would set the equations equal to each other
8x-8 = 5x+25
-5x -5x
Then i subtracted 5x from both sides
3x-8 = 25
+8 +8
Then I added 8 to both sides
3x = 33
Divide both sides by three and you'll get x=11

What is the value of x?
Answer:
x = 6
Step-by-step explanation:
Use the exterior angle theorem, which states that the 2 opposite interior angles add up to the measure of the exterior angle.
Set up an equation:
(8x - 13) + (9x - 10) = 11x + 13
Add like terms and solve for x:
17x - 23 = 11x + 13
6x - 23 = 13
6x = 36
x = 6
So, x = 6

solve for w and simplify this fraction 3/2w=-20
Answer:
If I'm correct, the answer should be negative 40/3.
Step-by-step explanation:
Because you first combine multiplied terms into a single fraction, then you multiply all terms by the same value to eliminate fraction denominators. Now you simplify it, by canceling multiplied terms that are in the denominator and then you multiply the numbers. Now you will divide both sides of the equation by the same term. Finally, you will simplify the equation.

A T-shirt takes ten minutes to make and a sweatshirt takes 20 minutes
to make. You have at most 20 hours to make shirts. The supplies for a
T-shirt cost $4 and the supplies for a sweatshirt cost $20. You want to
spend no more then $600 on supplies. You want to have at least 50
items to sell. How many T-shirts and how many sweatshirts should you
make to maximize your profit? The profit per T-shirt is $6 and the profit
per sweatshirt is $20,
I would use T-Shirts as sweatshirts make you no profit. 20 hours = 1200 / 10 (cuz it takes 10 min) = 120.
So you can make 120 shirts. 120 x4(for the cost of supplies) =$ 480.
you would make profit of 120 x 6 = 720.
720 - 480 = 240.
You would make $240 profit of making 120 shirts

Vera went to the local salon to get a haircut. The cost was $24. Vera tipped the hair stylist 18%. What was the total cost of the haircut including the tip? Round to the nearest cent.
Answer:
28.32
Step-by-step explanation:
The total cost of the haircut including the tip will be $28.32.
How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
It is given that Vera went to the local salon to get a haircut. The cost was $24. Vera tipped the hair stylist 18%.
SO,
18% = 18/100 = 0.18
18% of 24 = 0.18*24
= 4.32
The tip is $4.32
Adding this tip amount onto the original bill leads to;
4.32+24 = 28.32
Hence, the total cost of the haircut including the tip will be $28.32.
