GREG PUTS MONEY IN HIS DAUGHTERS PIGGY BANK EVERY DAY HE PUTS IN $0.75 BUT ON SUNDAYS HE PUTS IN $5.75 IF HE CONTINUES THUS FOR

Harman [31]

Greg's daughter will have $533 in her piggy bank in a year

The money in the piggy bank would increase everyday by the amount put in it. There are seven days in a week. If he puts $0.75 everyday apart from on Sundays when we puts $5.75, the amount that would be in the piggy bank in a week is the sum of the money deposited each day.

Total amount in a week = total amount deposited from Monday to Saturday + amount deposited on Sunday

Amount that Greg puts in 6 days : ($0.75 x 6) = $4.50
Amount deposited on Sunday = $5.75
Total amount = $5.75 + $4.50 = $10.25

The total amount Greg's daughter would have in a year is a function of the number of weeks in year and the total amount saved in a week

Total amount in a year = number of weeks in year x the total amount saved in a week

Number of weeks in year = 52
The total amount saved in a week = $10.25

$10.25 x 52 = $533

In order to determine how much Greg's daughter would have in a year, first determine how much she would have in a week. Multiply this amount by the number of weeks in a year

In a grid of a backyard, the vertices of the floor of a shed are (20, 80), (50, 60), (50, 20), and (20, 20). The coordinates are

sdas [7]

Answer:

The area of the floor of the shed is <u>1500 square feet.</u>

Step-by-step explanation:

Given:

The vertices of the floor of a shed are: (20,80), (50,60), (50,20) and (20,20)

Let us plot the given vertices on a graph.

From the graph, it is clear that the given figure is a trapezium with opposite parallel sides being parallel to the y axis. The height of the trapezium is the side that is parallel to x axis.

The area of the trapezium ABCD is given as:

$A=\frac{1}{2}(AB+CD)\times AD$

From the graph, AB = 60 ft, CD = 40 ft, AD = 30 ft

Therefore, the area is given as:

$A=\frac{1}{2}(60+40)\times 30\\A=\frac{1}{2}\times 100\times 30=1500\ ft^2$

Therefore, the area of the floor of the shed is 1500 square feet.

Can someone help me with part b on this question please?

Galina-37 [17]

Answer:

12.0 cm

Step-by-step explanation:

The Pythagorean theorem applies:

(12 cm)² +b² = (17 cm)²

b² = (289 -144) cm² = 145 cm²

b = √145 cm ≈ 12.04 cm

b ≈ 12.0 cm . . . . rounded to 1 decimal place
