This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find th

NISA [10]

Answer:

The volume of the triangular prism: 59.2 $ft^{3}$

The value of the concrete used is: 16*4 = $64

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo

My answer:

As we know that, the formula to find out the volume of the triangular prism is:

V = $\frac{1}{2} a*b*h$ when h is the height and a&b are the length of the two square edges. So we have:

V = $\frac{1}{2}$ *4*4*7.4 = 59.2 $ft^{3}$

To find the concrete used in the ramp if the cost of concrete is $ 4.00 per cubic foot, we need to know the area of the ramp, which is:

S = 4*4 = 16 $ft^{2}$

Hence, the value of the concrete used is: 16*4 = $64

strojnjashka [21]

Answer:

2x + y = 15

Step-by-step explanation:

Total amount with Manuel = $15

Cost of apps = $2

Cost of song = $1

x = number of apps purchased

y = number of songs purchased

Cost of apps × number of apps purchased + Cost of song × number of songs purchased = Total amount with Manuel

2*x + 1*y = 15

2x + y = 15

The linear equation that represents the combination of apps and songs manuel can purchase is 2x + y = 15
