y=70
step by step explanation:
In the question,
<em>Si</em><em>nce</em><em> </em><em>the</em><em> </em><em>trian</em><em>gle</em><em> </em><em>two</em><em> </em><em>sides</em><em> of</em><em> the</em><em> </em><em>traingl</em><em>e</em><em> </em><em>is</em><em> </em><em>equal</em><em>,</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> </em><em>triangle</em><em>.</em>

Answer:
1. 5 cups of yellow paint.
2. 15 cups of yellow paint to 3 cups of blue paint.
3. 1:5 is the proportional relationship.
4. 5 is the constant of proportionality, it represents the . of yellow cups of paint.
Step-by-step explanation:
sorry if 4 is wrong
I believe the answer is D because if you use the largest number in that group of numbers and divide that by 6 you get 6.6666 which is less than 7
Therefore the answer is D
4)
I:3x+4y=67
II:5x-y=35
to eliminate y when they are added one of the equations must contain -ay and the other +ay (with a being some number)
in this case we have in I already a positive term and in II a negative, but they have different numbers
by using multiplication (property of equations) we can multiply II by 4 so the negative and positive parts match
II*4: 20x-4y=140
when I and 4*II get added this results in
3x+20x+4y-4y=67+140
23x=207
5)
in this case I and II were added which can be seen in the left side of the equation((3x+4y)+(5x-y)=8x+3y), so to get the right side we have to also add the right sides 67+35=102
so the full equation would be:
8x+3y=102
Answer:
9,216π or 28,938.2 meters³
Step-by-step explanation:
Given: diameter 48 inches
Radius 24 inches
Note:
Volume of hemisphere = volume of sphere / 2
Volume of hemisphere = 1/2 • 4/3 • πr³
= 1/2• 4/3×π×24³
= 1/2•18432π
= 9,216π
= 28,938.2 meters³
