Answer:
The replacing the grass will cost Mr. Ishimoto $14.00.
Step-by-step explanation:
The area of a rectangular field is:

It is provided that Mr. Ishimoto needs to replace the grass in the section of his lawn.
The grass section can be broken into 2 rectangles.
First rectangle: Base = 7 feet and Height = 3 feet.
Second rectangle: Base = 2 feet and Height = 7 feet.
Compute the area of both the rectangles as follows:

Now the cost of the new grass is $0.40 per square foot.
Compute the cost of replacing the grass in the first rectangular section as follows:


Compute the cost of replacing the grass in the second rectangular section as follows:


The total cost of replacing the grass is:


Thus, the replacing the grass will cost Mr. Ishimoto $14.00.
Answer:
f(32)=3
Step-by-step explanation:
once again plug 32 in for X and you end up with 3
Answer:
B. 33
Step-by-step explanation:
Let the number of Fuji trees be F, the number of gala be G and the total number of trees be x.
10% cross pollinated, this means 1/10 cross pollinated or 0.1x
Number of Fuji plus cross pollinated is 187.
And cross pollinated is 3/4 of total or let’s say 0.75 of total which is 0.75x
Now, adding 0.1x + 0.75x would equal 187
0.85x = 187
x = 187/0.85 = 220 trees
The total number of trees is 220.
The number of gala trees is thus 220 - 187 = 33 trees
Let x be the number of 20 ton cars
Then,
380<{15(22-x)+20x}<400
380<{330-15x+20x}<400
380<{330+5x}<400
Subtract 330 on both sides
50<5x<70
Divide both sides by 5;
10<x<14
Therefore, the range of 20 tonne cars is between 10 and 14 cars.
