Mathematics
1 answer:
emmasim [6.3K]3 years ago
8 0

Answer:

Step-by-step explanation:

It is clear that the wall makes a right angle with the ground. Therefore, we can apply Pythagoras theorem to get its sides.

Hypotenuse ^2= altitude^2+ base^2

altitude ^2=hypotenuse^2-base^2

=13^2-5^2

=144

Altitude/the point where the ladder meets the wall = 12.(√144)

The unit cost of the fencing and the cost of a bag of mulch together with

the area and perimeter of the garden give a cost sum of $36.5.

Response:

  • The amount required to spend is <u>$36.5</u>

<h3>How does the unit cost determine the total cost?</h3>

Cost of the barrier per feet (unit cost) = $0.75

Area covered by one bag of mulch = 7 square feet

Cost of one bag of mulch (unit cost) = $5

From the given diagram, we have;

Area of the garden = 8 ft. × 2 ft. + 0.5 × 8 ft. × 3 ft. = 28 ft.²

Number \ of \ bags \ of \ mulch \ required = \dfrac{28 \, ft.^2}{7 \, ft.^2/ bag} = \mathbf{ 4 \, bags}

Length of fencing = 2 ft. + 8 ft. + 2 ft. + 5 ft. 5 ft. = 22 ft.

  • Amount to spend = 4 bags × $5 + 22 ft. × $0.75 =<u> $36.5</u>

A 5-gallon bucket is full of pure water. Suppose we begin dumping salt into the bucket at a rate of 1/4 pounds per minute. Also,
Tatiana [17]

Answer and explanation:

1. In one minute, there would be zero pounds of salt in the bucket because there's 0.25 pounds of salt in one minute and 0.5 gallons of water leaves the bucket in same minute, eliminating the 0.25 pounds of salt.

2. In ten minutes there would be zero pounds of salt because theres 0.25×10= 2.5 pounds of salt and 0.5×10=5 gallons of water would leave the bucket, eliminating the salt.

3. In 60 minutes there would still be zero salt because water leaves the bucket more than salt enters

4. Zero salt too after bucket leaks

5. Zero salt
