Bruce bought 5/8 ounces of peppers and 2/3 ounces of onions. How many more ounces of onions did he buy compared to peppers?
Answer:
The price of one pound of bell peppers is $0.6.
Step-by-step explanation:
This problem is equivalent to the following:
"if 10 oranges cost $20, how much does 1 orange cost? "and the answer to that question is:
price of 1 orange = $20/ 10 oranges = $2 per orange.
Put simply, we divided the total price by the total number of items, and we shall do the same thing for the case of bell peppers:
price of 1 pound = $1.25/ 2.5 pounds = $0.5/ pound.
The price for 1 pound of bell peppers is $0.5.

You are having a movie marathon. Each movie lasts about 12 hours.
If you want to watch 4 movies, how long will your movie marathon last?
Answer:
Your movie marathon will last 6 hours.
Step-by-step explanation:
This question can be solved using a rule of three.
Each movie lasts hours. How much do 4 movies last?
So
1 movie - 1.5 hours
4 movies - x hours
x = 4*1.5 = 6
Your movie marathon will last 6 hours.
Answer:
48 hours or 2 days
Step-by-step explanation:
There are 4 movies
Each movie lasts 12 hours
4 x 12 or 12 x 4 equals 48
The marathon lasts 48 hours
In a certain year, a magnitude 7.8 earthquake struck California. In another year, a magnitude 5.8 quake struck Kansas. How many times as intense as the Kansas quake was the California quake?
Answer:
The California quake was 1.34 times as intense as the Kansas quake.
Step-by-step explanation:
To find how many times as intense as Kansas (K) quake was the California (C) quake first, we need to find the ratio of intensity (I) between those earthquakes:
[tex] \frac{I_{C}}{I_{K}} = \frac{7.8}{5.8} = 1.34 [/tex]
Now, by multiplying the above number for the intensity of the Kansas quake we should have the intensity of the California quake:
[tex] I_{K} = 1.34*5.8 = 7.8 [/tex]
Therefore, the California quake was 1.34 times as intense as the Kansas quake.
I hope it helps you!

HELP PLEASE ! Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y= -1/3x+4
Answer:
y = 3x - 9
Step-by-step explanation:
✔️Find the slope of the line perpendicular to the given graph of equation:
A line that is perpendicular to the graph of the equation y = -⅓x + 4, will have a slope value that is the negative reciprocal of the slope of the graph of the given equation.
The slope of y = -⅓x + 4 is -⅓.
Negative reciprocal of -⅓ = 3
Slope of the line (m) = 3
✔️Find the y-intercept (b):
Substitute (x, y) = (4, 3) and m = 3 into y = mx + b
3 = 3(4) + b
3 = 12 + b
3 - 12 = b
-9 = b
b = -9
✔️Write the equation:
Substitute m = 3 and b = -9 into y = mx + b
y = 3x + (-9)
y = 3x - 9

A surfboard that has a regular price of $150 is on sale at a 40% discount. What is the sale price with a 9% tax?
Answer:
$98.10
Step-by-step explanation:
150 decrease 40% =
150 × (1 - 40%) = 150 × (1 - 0.4) = 90
90 increase 9% =
90 × (1 + 9%) = 90 × (1 + 0.09) = 98.1
The ratio of rainbow trout to mackinaw released into a lake was 4:7. A total of 682 fish were released. How many were mackinaw?
Answer:
There are 450 trout in the lake.
B - brown trout;
R - rainbow trout.
B : R = 6 : 9 = 2 : 3
B = 2 t
R = 3 t
2 t + 3 t = 5 t
5 t = 450
t = 450 : 5
t = 90
R = 3 * 90 = 270
Answer:
There are 270 rainbow trout in the lake.

Which point on the coordinate plane below is (-9, 3)?
Point D
Point C
Point B
Point A
Answer:B
Step-by-step explanation: x is -9 and y is 3
Since it’s negative you’d go left by 9 blocks and the y is positive so you go up 3
Answer:
The answer is point B
Step-by-step explanation:
I know this because (-9, 3) seems to be located in quadrant 2 because in quadrant 2 along the x-axis it is negative and along the y-axis it is positive. So, when l look in quadrant 2 there seems to be only one point, point B, which if you look at it is 9 units to the left and 3 units upward.
Robert is serving 16 drinks to his friends. Three times as many friends are drinking lemonade as tea, and 4 are drinking water. How many of each type of drink does Robert serve?
Answer:
9 lemonade, 3 tea, 4 water
Answer: Robert should serve 3 for tea, 9 for lemonade, and 4 for water.
Step-by-step explanation:
Since you don't know how many friends are drinking lemonade or tea, you should give them variables.
x = amount of friends drinking tea
3x = amount of friends drinking lemonade
We already know how many are drinking water, so there's no need for a variable.
Then, make an equation:
x + 3x + 4 = 16
Simplify:
4x + 4 = 16
Isolate the variable by subtracting 4 from both sides:
4x = 12
Isolate the variable by dividing both sides by 4:
x = 3, so 3 friends are drinking tea
3x = 9, so 9 friends are drinking lemonade
Double check the work by replacing the variables with their actual numbers:
3 + 9 + 4 = 16
Simplify:
16 = 16
Therefore, the answer is correct.
if x is a positive integer, for how many dofferent values of x is square root 48 over x a whole number
