Answer:3 to 2
Step-by-step explanation: 6:4 reduces to 3:2
Answer:
scale factor = 1/2
Step-by-step explanation:
for AC: 4 + 4 = 8
8 is the AC of the red triangle
4 is the AC of the blue triangle
to get from 8 to 4, we divide by 2 or multiply by 1/2 (they mean the same thing)
10 is the CB of the red triangle
5 is the CB of the blue triangle
to get from 10 to 5, we divide by 2 or multiply by 1/2
Given equation : -6x+3y=18.9.
We need to find x and y-intercepts.
<em>In order to find the x-intercept, we need to plug y=0 and solve the equation for x.</em>
Plugging x=0 in given equation, we get
-6(0)+3y=18.9
0 +3y = 18.9
3y = 18.9
Dividing both sides by 3, we get
y = 6.3
<em>In order to find the y-intercept, we need to plug x=0 and solve the equation for y.</em>
Plugging y=0 in given equation, we get
-6x+3(0)=18.9
-6x = 18.9
Dividing both sides by -6, we get
x = -3.15.
<h3>Therefore, x-intercept is -3.15 and y-intercept is 6.3.</h3>
We could write them as coordinates
<h3>x-intercept (-3.15, 0) </h3><h3>y-intercept (0, 6.3).</h3>
Answer: 16
Step-by-step explanation:
The constant of proportionality is a ratio that exist between two directly proportional quantities. From the question, recipe says to use 1.5 cups of flour to make 24 cookies.
y = the number of cookies made
x = the number of cups of flour used
y = kx
k = y/x
k = 24/1.5
k = 16
Therefore, the constant of proportionality which relates the number of cookies made, y, to number of cups of flour used, x is 16.
