Joseph and Molly each have coin collections. Joseph starts with 15 coins in his collection and adds 25 coins each month. Molly starts with 25 coins in her collection and adds 25 coins each month. If Joseph and Molly continue to collect in this way, how many coins will each person have after 10 months? Enter your answers in the boxes. After 10 months, Joseph will have coins in his collection, and Molly will have coins in her collection.

Answers

Answer:

Joseph will have 265 coins and Molly will have 275 coins after ten months.

Explanation:

Joseph already has 15 coins and adds 25 coins after each month. So after ten months the total number of coins Joseph will have is [tex]15+25\times 10=265[/tex] coins.

Molly already has 25 coins and adds 25 coins after each month. So after ten months the total number of coins Joseph will have is [tex]25+25\times 10=275[/tex] coins.

So, Joseph will have 265 coins and Molly will have 275 coins after ten months.

(HELP WANTED AUTOMATIC BRAINLY) Which statement describes how the muscular and skeletal systems cause parts of the body to move?
A. When a muscle relaxes, it causes a bone to shorten.
B. When a bone shortens, it lengthens the muscle attached to it.
C. When a bone bends, it pushes a muscle in the opposite direction.
D. When a muscle contracts, it pulls a bone in one direction.

Answers

Answer:

C.

Explanation: Because when a bone does bend the muscles pull back so the bone doesnt dislocate.

The statement describes how the muscular and skeletal systems cause parts of the body to move is when a muscle contracts, it pulls a bone in one direction.

What is skeletal system?

The skeletal system is the in charge of all the bones and skeleton of the body. The skeletal system provides structure and strength to the body and protects the soft tissues.

The muscular system and the skeletal system work together as the muscles and bones are connected with each other.

\/(*^*)\/

Explanation:

Based on the graph in Figure 2, identify the environmental conditions (flower density AND proportion of deep flowers) where a short- tongued bee has the greatest relative advantage over a long tongued bee. Based on the graph in Figure 2, identify the range of proportion of deep flowers at which a long tongued- bee always has an advantage over a short tongued bee.

Answers

Answer:

The correct answer would be - low flower density and low deep flower proportion

Explanation:

To find the environmental conditions for a short-tongued bee has the greatest relative advantage over long-tongued bees it is required to find the highest value of relative advantage short-tongued bees has on long-tongued bees which is the point where flower density and deep flower proportion is lowest (near the zero) according to the graph. That is represented in the graph by the peak in the white shaded portion.

To find the range of deep flower proportion at which a long-tongued bee has an advantage take a closer look to the grey shaded area where if the deep flower proportion move from 0.6 to 1 the advantage of long-tongued bees over short-tongued.

Floral density with the graph shows the low flower density and low deep flower proportion. Floral density often influences the species composition of flower visitors.

This variation in visitor species composition has significant effects on pollination success and plant fitness, poorly understood, especially in the many pollination guilds dominated by non-territorial species.

How do flower visitors diverse the traits?

It explores how flower visitors with diverse traits should distribute themselves across resource patches differing in floral density.

The model predicts that species with low flower search speeds and low flower handling costs compared to competitors will usually dominate dense flower patches.

In addition, amongst flower visitors that have lower energy expenditure rates while handling flowers than while traveling, species maximizing energetic efficiency are associated with dense flower patches.

Therefore, the correct answer is low flower density and low deep flower proportion.

Answers

Incomplete question. Attached is the image of the map below.

Explanation:

From the map, we could notice the contour lines around the Chimney Bluff areas are closely packed together. In other words, the spacing between the contour lines is narrower than those found in other locations.

This assertion is accurate because it is a standard practice in many maps to indicate the steepness of an area by having the contour lines in close proximity.
