Let's first turn 1 9/10 into an improper fraction, which is 19/10

so if R/12 equa;s 19/10, cross multiply

10r equals 228

divide both sides by 10, you get r= 22.8

The volume of the rectangular prism can be found with the formula
v= length × width × height
V = 10×10×30 = 3000

the volume of the triangular prism can be found with
v = 1/2(base×width×height)
v=1/2×30×9×10 = 1/2×2700
v = 1350

Now add the two volumes together for the total volume...

3000+1350 = 4,350 in^3

How do you solve: 4/10y+28=0
Bezzdna [24]

Answer:

<h2>y = -70</h2>

Step-by-step explanation:

\dfrac{4}{10}y+28=0\qquad\text{subtract 28 from both sides}\\\\\dfrac{4:2}{10:2}y=-28\\\\\dfrac{2}{5}y=-28\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{2}{5\!\!\!\!\diagup_1}y=-140\\\\2y=-140\qquad\text{divide both sides by 2}\\\\y=-70
