X= number of nickels
3x= number of dimes
Each nickel is $0.05 and each dime is $0.10. Multiply each coins monetary value by the quantity of each. Add them equal to the total $9.10.
(0.05 * x) + (0.10 * 3x)= 9.10
multiply inside parentheses
0.05x + 0.3x= 9.10
add
0.35x= 9.10
divide both sides by 0.35x
x= 26 nickels
DIMES
3x= 3(26)= 78 dimes
CHECK:
(26 nickels * 0.05) + (78 dimes * 0.10)= 9.10
$1.30 + $7.80= $9.10
$9.10= $9.10
ANSWER: There are 26 nickels and 78 dimes.
Hope this helps! :)
Answer:
Width = 6.45 cm
Length = 8.6 cm
Step-by-step explanation:
the sides of a rectangle are such that the width is three-quarters of the length. if the diagonal is 15cm find the length and the width.
From the question,
W = 3/4L
W = 3L/4
When given diagonal,
W² + L² = D²
Where, D = Diagonal
W = Width
L = Length
Hence, Substituting 3L/4 for W
(3L/4)² + L² = 15²
9L²/16 + L² = 225
L²(9/16 + 1) = 225
Divide both side by 9/16 + 1
L² = 225/(9/16 + 1)
Square root both side
L = √225/(9/16 + 1)
L = 15/3/4 + 1
L = 15 ÷ 1 3/4
L = 15 ÷ 7/4
L = 15 × 4/7
L = 8.6cm
W = 3L/4
W = 3(8.6)/4
W = 6.45cm
Answers:
1.)529.934 sq feet
2.) $185,260
3.)(usd) $349.59 per square foot
Explanation:
1.) 1 meter is 3ft and 3.37 inches. All you have to do is multiply that by 160
2.)one euro is worth 1.18 usd, so all you have to do is multiply the amount of euros (157,000) by 1.18
3.) this uses a combination of what we have gotten. You have to divide the total price in usd (185,260) by the amount of square feet there are (529.934)

From the division computed, it should be noted that the number of hours that the battery will be able to provide 7 amperes will be 50 hours.
The information given is about the division of numbers. It was stated that the battery is rated at 350 ampere-hours.
The number of hours that it will be able to provide 7 amperes will be:
= 350 / 7
= 50 hours.
