<span>We need to divide 72 rolls into 2 groups so that their ratio is 3:5. First, we can see that the ratio of 3:5 tells us there is 8 separate groups of rolls. Now its easy, since we have 72 rolls and we need to divide them into 8 equal groups: 72/8=9. So each group has 9 rolls. Now we separate them into groups with the ratio 3:5, so: 3*9:5*9 and that is: 27 rolls and 45 rolls. </span>

Answer:
Below
Step-by-step explanation:
Let's say that each square on the grid represents 1 cm
First find the area of the two triangles
For the larger one: A = bh/2
A = 3 x 3 / 2
= 4.5 cm^2
For the smaller one : A = bh/2
A = 2 x 2 / 2
= 2 cm^2
For the rectangle : A = lw
A = 4 x 5
= 20 cm^2
Add them all up to get the area
4.5 + 2 + 20 = 26.5 cm^2
Hope this helps!
Answer:
X=9 Angle= 55
Step-by-step explanation:
The sum of all the angles of a triangle is always 180
so we add the angles
50 + 75 + (5x + 10)=180
125 +5x+ 10=180
135 +5x = 180
5x= 45
x=9
to find the angle we substitute x for 9
5(9)+10=55
Answer:
m∠2 = 118, and m∠3 = 31
Step-by-step explanation:
The 2 opposite angles of a rhombus are equal.
Angle 1 and Angle 2 are opposite to each other. Since Angle 1 is 118, angle 2 is also 118.
Now looking at the bottom triangle in the rhombus, the two sides are equal (given by 2 lines). Hence, the 2 opposite angles are equal. Since we know 3 angles of a triangle add up to 180 degrees, we can write: (let angle 3 be x):
x + x + 118 = 180
2x = 180 - 118
2x = 62
x = 62/2
x = 31
So m∠2 = 118, and m∠3 = 31
