Please help me with this ACT Prep problem.

Answer:

Option C

Step-by-step explanation:

ΔABC and ΔDEF are similar triangles.

By the property of similar triangles, corresponding sides of the similar triangle are proportional.

\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}

\frac{6}{DE}=\frac{6}{3}=\frac{10}{5}

\frac{6}{DE}=\frac{6}{3}

DE = 3

Perimeter of ΔDEF = Sum of measures of the sides of the triangle

                                = DE + EF + DF

                                = 3 + 3 + 5

                                = 11

Therefore, Option C will be the correct option.

The density of concentrated sulphuric acid is 1.8 g/cm.calculate the volume of 3.1 kg of the acid​
Sphinxa [80]

Step-by-step explanation:

density =  \frac{mass}{volume} \\ volume =  \frac{mass}{density}  \\ changing \: 1.8 {gcm}^{ - 3} to \:  {kgm}^{ - 3}  \\ multiply \: by \: 1000 \\  = 1800 {kgm}^{ - 3}  \\ volume =  \frac{3.1}{1800}  \\  = 0.00172 {m}^{ 3}

One day last summer, Jim went kayaking on the Little Susitna River in Alaska. Paddling upstream against the current, he traveled
miv72 [106K]

Answer:

6.5 miles per hour

Step-by-step explanation:

At first, Jim was paddling against the current for 3 hours. Then, he paddled for 1 hour with the help of the current.

Let x be Jim's rate without the current and y be the rate of the current:

(x-y)*3=12\\(x+y)*1=17

By solving the linear system, we can find the rate of the current y:

x=17-y\\(17-y-y)*3=12\\y=\frac{39}{6}\\y=6.5\ \frac{miles}{hour}

The current has a rate of 6.5 miles per hour.
