John and Maria are spending the afternoon hiking in the desert. They purchased 6 bottles of water for $9.00, two protein bars for $5.00, and some peanuts for $3.00 as a snack. Suppose they star hiking at 11.30 A.M. and finish the hike at 3.45 P.M. What is the unit rate of money spent to hours hiked? Show your work.

Answers

Answer:

They spent $4 per hour hiked.

Step-by-step explanation:

They spent

$9.00 in water.
$5.00 in protein bars.
$3.00 in peanuts.

Total cost $17.

Now, if the hiked from 11.30 AM to 3.45 PM, then they hike for 4 hours and 15 minutes. However, we need to transform those minutes into hours before we find the rate

$15min(1hr)/(60min)=(1)/(4)hr=0.25hr$

So, they hiked for 4.25 hours.

Then, to find the unit rate of money spent per hour hiked, we just need to divide $17 by 4.25 hr.

$(\$17)/(4.25hr)=4(\$)/(hr)$

Therefore, they spent $4 per hour hiked.

for irregular shapes, simply cut the shapes into recognizable shapes like square, rectangle, triangle. Solve the area of each shape and add it up to get the total area of the irregular shape.

1) rectangle 1 = 5cm * 3cm = 15cm²
rectangle 2 = 2cm * 4cm = 8cm²
15cm² + 8cm² = 23 cm²

2) rectangle 1 = 9cm * (10cm-6cm) = 9cm * 4cm = 36cm²
rectangle 2 = 6cm * 2cm = 12cm²
36cm² + 12cm² = 48cm²

3) square 1 = (2cm)² = 4cm²
square 2 = (4cm)² = 16cm²
shaded area only. subtraction performed.
16cm² - 4cm² = 12cm²

4) square = (10cm)² = 100cm
triangle = (10cm * 10cm)/2 = 100cm² / 2 = 50cm²
100cm² + 50cm² = 150cm²

5) rectangle 1 = 4mm * 3mm = 12mm²
rectangle 2 = 8mm * 10mm = 80mm²
12mm² + 80mm² = 92mm²

it is (C) because the line is ZERO meaning the line is vertical and since it goes through 5, it is y=5 cuz u always have the formula for slope; y=mx+b and since there is o x intercept you just stick with the y intercept which is 5 so long story short, it is y=5 (c)
