535.25 is the answer bc you add the deposits and subtract the withdrawals
after April 13th Raul would have $535.25 on his account

explanation:

on 4/2 the balance was $539.50
on 4/2 $35.50 was taken out of the account
on 4/6 $23.75 was taken out of the account
on 4/13 $55.00 was added to the account

that means in all, $59.25 was taken out of the account
so, taking it out of the original balance,
539.50 - 59.25 = $480.25
but $55.00 was then added to the account so we add it to the new balance.
$480.25 + $55.00 = $535.25

so, that’s means there is now $535.25 on the account

Sam walked to a nearby shop to purchase a gallon of ice cream. The shop is 400 meters from his house, and it took him 4 minutes to get there. At the shop, it took 2 minutes to choose a flavor and purchase the ice cream. He walked home in 3 minutes, at a faster pace than before so the ice cream wouldn’t melt.

Draw a graph that models Sam’s distance from home (in meters) in terms of time (in minutes). Label the graph with appropriate intervals and units.

Answers

Answer:

  see the attached graph

Step-by-step explanation:

The axes and units for the graph are given in the problem statement. The range of the graph is also given, but figuring the domain requires a little arithmetic. We assume the walking pace is constant, so the graph will be piecewise linear.

Axes

The vertical (y) axis is labeled with what the graph is modeling, "distance from home (in meters)." The horizontal (x) axis is labeled with what the model is in terms of "time (in minutes)."

The range of the graph is 0 to 400 meters, the range of distances Sam may be from home.

The domain of the graph is 0 to 9 minutes. The time it takes to complete the trip is 4 minutes to the shop, 2 minutes at the shop, and 3 minutes coming home, for a total of 4+2+3 = 9 minutes.

Graph

We are given that points on the graph will be (0, 0), (4, 400), (6, 400), and (9, 0). That is Sam is ...

at home at 0 minutes400 meters from home (at the shop) after 4 minutesremaining 400 meters from home for 2 more minutes (until 6 minutes)at home after 3 more minutes (at 9 minutes).

Since we assume walking is at a steady pace, we connect these dots with straight lines. The resulting graph is attached.

Estimate the perimeter of the figure.

A. about 20.5 units

B. about 25.5 units

The questions:
The figure shows the dimensions of a backyard. Find the area.
The area of the backyard is ______ square yards.

Answers

7273

......................

Answer: 700yd^2

Step-by-step explanation:

Area of Square - Area of Triangle

Area of Square: 30^2 = 900yd^2

Area of Triangle: (20) (20) / 2 = 200 yd^2

from the left side we can see the whole side is 30yd long. On the right we see its only 10 yd, meaning the triangle takes up the remaning 20yds. The whole bottom line equals 40 yd. The top line is only 20yd, leaving the other 20yd for the triangle.

900 - 200 = 700yd^2
