Answer:
y=3x+3
Step-by-step explanation:
slope is 3 because rise over run. Rise is 3 and run is 1. 3/1 is 3. and b= y-intercept and the poiunt wehre the line intercepts the y axis is 3. so your answer is y=3x+3
X+y=15
0.3x+0.6y=0.4*15=6
solve the system of equation.
Multiply equation one by 0.3: 0.3x+0.3y=4.5
subtract the new from the second equation: 0.3y=1.5
y=5
x=10
The way to multiply fractions include:
- The first step when multiplying fractions is simply to multiply the two numerators.
- The second step is to multiply the two denominators.
- Finally, simplify the new fractions
<h3>What are fractions?</h3>
It is important to note that fractions are part of whole numbers.
Fir example, to multiply 2/3 by 1/5 will be:
= 2/3 × 1/5
= 2/15
In conclusion, one has to multiply the numerator and them multiply the denominator.

Answer:
I think B is the correct choice.
Answer:
C. 134.04 
Step-by-step explanation:
The formula to calculate the volume of the cone is:
+) <em>Volume of a cone = 1/3 x Area of base x Height</em>
<em />
The base of the cone is a circle, so that the formula to calculate the are of the base is: <em>Area of base = </em>
x
The radius of the base is 4cm
=> <em>Area of base = </em>
x 4^2 = 3.14 x 16 = 16

The height of the cone is given equal to 8 cm
So the volume of the cone is:
+) <em>Volume of a cone = 1/3 x Area of base x Height = 1/3 x 16</em>
<em> x 8 = 134.04 </em>
<em />
<em />
So the answer is C
