Answer:
20%
Step-by-step explanation:
Step one:
given data
Normal price = £24
Sale price of $19.20
From the data above, the price has been marked down by a certain percent
Required
The percent mark down
Step two:
Percent mark down= Normal-sale/Normal*100
Percent mark down= 24-19.20/24*100
Percent mark down= 4.8/24*100
Percent mark down=0.2*100
Percent mark down=20%
<h3>Given:</h3>
PQRS is a rectangle.
PS = 5cm
PQ = 12cm
<h3>To Find:</h3>
The length of qr ,sr and the two diagonals pr and qs.
<h3>Solution:</h3>
Opposite sides of a rectangle are equal.
QR = PS = 5cm
SR = PQ = 12cm
By using Pythagoras Theorem, we get
PR = √PS^2 + SR^2
or, PR = √25 + 144
or, PR = √169
or, PR = 13cm
Diagonals of a rectangle are equal.
QS = PR = 13cm
<h2>Answer:</h2>
QR = 5 cm
SR = 12 cm
PR = 13 cm
QS = 13 cm
Answer:
L = 14/
<u>OR</u> 9.899
Step-by-step explanation:
cos(angle) = adjacent/ hypotenuse
hypotenuse = length of ladder
adjacent = 7 feet
length of ladder = L
1/L = cos(45)/7
L = 7/cos(45)
<u><em>MAKE SURE CALCULATOR IS IN DEGREE MODE</em></u>
L = 7/(
/2)
L = 14/
WHERES THE CALCULATOR_____ WHERE IS IT
The answer to the question would be 2 3/8
Hope this helps.
