vredina [299]

Answer: 4.1 feet : 4 feet

Step-by-step explanation:

From the question, we are informed that Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.

The conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet goes thus:

Since 1 feet = 0.305 meters

2.5 meters will be = 2.5/0.305 = 8.2 feet

Therefore the conversion ratio will be:.

= 8.2 : 8

Reducing to lowest term will be

= 4.1 feet : 4 feet.

= 4.1 : 4

The answer is the second choice, or B; 240 ft^2.

You have to find the area of all four triangles and just add those all together. 

Two of the triangles have an area of 
5*16=80
Multiply that by two
80*2=160

The other two smaller triangles have an area of 
8*5=40
Multiply that by 2 also
40*2=80

Add 160+80 and the answer is 240.

frozen [14]

Answer:

2\frac{2}{3}\text{ ft}^3\approx 2.67\text{ ft}^3

Step-by-step explanation:

We have been given that Martha has 8 cubic feet of putting soil in the 3 flowerpots. She wants to put the same amount of soil in each pot.

To find the amount of soil in each pot, we need to divide total soil (8 cubic feet) by number of pots (3) as shown below:

\text{Amount of soil in each pot}=\frac{8\text{ ft}^3}{3}

\text{Amount of soil in each pot}=2\frac{2}{3}\text{ ft}^3

\text{Amount of soil in each pot}=2.6666\text{ ft}^3

\text{Amount of soil in each pot}\approx 2.67\text{ ft}^3

Therefore, Martha needs to put approximately 2.67 cubic feet of soil in each flower pot.

Triangle ABC has coordinates A (0, 1) B (0, 2) and C (3,2). If Triangle ABC is equivalent to triangle EDF, what is the measure o
Elanso [62]

Answer:

  3

Step-by-step explanation:

Segment BC corresponds to segment DF. The length of BC is the distance between coordinates (0, 2) and (3, 2). These points are on the same horizontal line (y=2), so the distance between them is the difference of their x-coordinates: 3 - 0 = 3.
