Marta's jump rope is 10" shorter than four times the length of Dilbert's rope. If both their ropes laid together end to end and
sladkih [1.3K]

Answer:

Marta's rope is 94"

Step-by-step explanation:

D = dilberts rope length

M = marta's rope length

Marta's jump rope is 10" shorter than four times the length of Dilbert's rope

M = 4D-10

both their ropes laid together end to end and measured 120" long

M+D = 120

Substitute 4D-10 for M in the second equation

4D-10 + D = 120

Combine like terms

5D-10=120

Add 10 to each side

5D-10+10 =120+10

5D =130

Divide by 5

5D/5 = 130/5

D =26

Now we need to find M

M+D = 120

M +26 = 120

Subtract 26 from each side

M = 120-26

M = 94

What is the surface area of the triangular prism Not drawn to scale 2001 2376 2592 4320
liq [111]

Answer:

Option B. 2376 Square feet

Step-by-step explanation:

The following were obtained obtained from the question:

Base (B) = 24ft

Length (L) = 40ft

Height (H) = 9ft

Slant height (S) = 15ft

Surface Area (A) =?

The surface area (A) for triangular prism is given below:

A = BH + 2LS + LB

Where:

B is the Base

L is the Length

H is the Height

S is the Slant Height

A is the Surface Area

Using the above equation, the surface area can be obtained as follow:

A = BH + 2LS + LB

A = (24x9) + (2x40x15) + (40x24)

A = 216 + 1200 + 960

A = 2376 ft2
