The table shows the height of Sonya‘s siblings who is taller Frida or Julia compare their hearts using the simple &gt;
Vladimir [108]

Answer:

The  height of Julio greater than  the height of Frieda .

Step-by-step explanation:

Given height as :

The height of Frieda = 5\frac{1}{4} ft

The height of Julio = 5\frac{5}{6} ft

So, The height of Frieda = 5\frac{1}{4}

                                         = 5 + \frac{1}{4}

                                         = \frac{20+1}{4}

                                         = \frac{21}{4}  feet

∴  The height of Frieda = 5.25 feet

And The height of Julio = 5\frac{5}{6} ft

So, The height of Julio    = 5\frac{5}{6}

                                         = 5 + \frac{5}{6}

                                         = \frac{30+5}{6}

                                         = \frac{35}{6}  feet

∴ The height of Julio    = 5.83 feet

Since 5.83 feet  > 5.25 feet

So  the height of Julio >  the height of Frieda

Hence The  height of Julio greater than  the height of Frieda . Answer

On cyber Monday a 40$ hard drive was discounted by 30%. If the tax rate in your city is 7%, what is the total cost of the hard d
Georgia [21]

The total cost of hard drive is $29.96

Step-by-step explanation:

Given,

Original price = $40

Discount = 30%

Discount amount = 30% of $40 = \frac{30}{100}*40

Discount amount=\frac{1200}{100}= \$12

Price after discount = Original price - discount amount

Price after discount = 40-12 = $28

Tax rate = 7%

Tax amount = 7% of price after discount

Tax\ amount=\frac{7}{100}*28\\Tax\ amount=\frac{196}{100}\\Tax\ amount=\$1.96

Total cost of hard drive = Price after discount + Tax amount

Total cost of hard drive = 28+1.96 = $29.96

The total cost of hard drive is $29.96

A rectangle has an area of 2020cm2. All side lengths are a whole number in centimetres. What is the greatest possible number of
MissTica

Answer:

The greatest possible number of centimeters in the perimeter of the rectangle is 1009.

Step-by-step explanation:

The perimeter of a rectangle with length l, and breadth b is given as

P = 2(l + b)

Since we are told it has an area of 2020 cm²,

This means that

2(l + b) = 2020

or

l + b = 1010

The length can be 1009cm while the breadth is 1cm l, or vice versa.

So, the greatest possible number of centimeters in the perimeter of the rectangle is 1009
