A ratio is written in the form a : b. In this case, there are 6 gray keys for every 7 blue keys. So the ratio for gray to blue keys would be 6:7.
Since 6 and 7 don't have common factors, the ratio 6:7 cannot be simplified further.
So the ratio for gray to blue keys is 6:7.
To find your answer you would need to add both colors(blue and green)
to do this you need to make the denominators the same :
24 is a number we can get 8 and 6 to :
1×4=4
6×4=24
5×3=15
8×3=24
your new fractions are 4/24 and 15/24, now we can add them :
4+15=19
and 24 stays the same
your answer is 19/24 (you can not simplify this)
hope this helped
Answer:
The minimum width of the placemat is 10 inches.
Step-by-step explanation:
Let suppose that placemat has a square form, whose width must be at least equal to the diameter of the pizza, so that pizza does not touch the table. Hence, the following relationship is obtained:
Where:
- Width of the placemat, measured in inches.
- Diameter of pizza, measured in inches.
The area of the pizza, measured in square inches, is determined by this formula:
The diameter is cleared afterwards:
If 
and 
, then:
The minimum width of the placemat is 10 inches.
Hello,
The function is y=4x+8.
We exchange x and y ==>x=4y+8
and we seach y:
4y=x-8 ==>y=(x-8)/4 ==> y=x/4-2
Answer A
Answer:
378.5 or just 378
Step-by-step explanation:
This is a linear model with x representing the number of generations that's gone by, y is the number of butterflies after x number of generations has gone by, and the 350 represents the number of butterflies initially (before any time has gone by. When x = 0, y = 350 so that's the y-intercept of our equation.)
The form for a linear equation is y = mx + b, where m is the rate of change and b is the y-intercept, the initial amount when x = 0.
Our rate of change is 1.5 and the initial amount of butterflies is 350, so filling in the equation we get a model of y = 1.5x + 350.
If we want y when x = 19, plug 19 in for x and solve for y:
y = 1.5(19) + 350
y = 378.5
Since we can't have .5 of a butterfly we will round down to 378
