The formula can be used to work outthe cost, in riyals, of hiring a helmet inQatar for a number of days.Kasun wants to hire a bi
Margaret [11]

Answer:

The answer is below

Step-by-step explanation:

a) Cost of hiring the bicycle for 14 days is:

Cost = 65 * 14 days + 44 = 954 riyals

b) The number of days the bicycle is hired is to be the same as the number of days the bicycle is to be hired. Let us assume that the bicycle and helmet is to be hired for x days, hence:

Cost of bicycle = 65 * x + 14 = 65x + 44

Cost of helmet = 12.5 * x = 12.5x

Total cost = 65x + 44 + 12.5x = 77.5x + 44

Since 750 riyals is available, hence:

750 = 77.5x + 44

77.5x = 706

x = 9.11

Therefore the maximum number of days is 11. The total cost for 11 days is:

Total cost = 77.5(9) + 44 = 741.5 riyals

Money not spent = 750 riyals - 741.5 riyals = 8.5 riyals

Point \blue{A}Astart color blue, A, end color blue is at \blue{(-4, 8)}(−4,8)start color blue, left parenthesis, minus, 4, comma
ASHA 777 [7]

Answer:

The coordinates of point B are (6,7).

Step-by-step explanation:

Given points are

Blue = A(-4,8)

Purple = M(1,7.5)

Green = B

It is given that point M is the midpoint of point A and B.

Let coordinates of points are (a,b).

Midpoint of two points is

Midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

M=(\dfrac{-4+a}{2},\dfrac{8+b}{2})

Coordinates of midpoint are (1,7.5).

(1,7.5)=(\dfrac{-4+a}{2},\dfrac{8+b}{2})

On comparing both sides we get

1=\dfrac{-4+a}{2}\Rightarrow 2=-4+a\Rightarrow a=6

7.5=\dfrac{8+b}{2}\Rightarrow 15=8+b\Rightarrow b=7

Therefore, the coordinates of point B are (6,7).

Karen's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 57 liters. What
guapka [62]

Answer:

Karen has to at least spend 11 minutes.

Step-by-step explanation:

This is because 57 - 13 = 44. 44 divided by 4 = 11. This means that in 11 minutes Karen will have a 57 liter tank. But she could keep going, but the least number of minutes would be 11 minutes, to get to 57 liters.

I hope this helps! Please mark me Brainliest if it did! Thank you and have a nice day!

EastWind [94]
5/g=n because the denominator is always the total amount and g is the total amount of granola bars in the box. And the 5 comes from the amount of kids that received the bars and the n is on the outside because your looking for that amount. I’m sorry if this doesn’t make sense, i tried my best to explain.
