John earned $12 a day for babysitting his siblings after school each weekday (he did not babysit on weekends). He liked to have

a small amount of money to spend on treats at the school canteen that his parents refuse to buy, but he also wanted to build up some savings. John decided to put a fraction of his earnings into a jar straight away. He spent all the rest on canteen treats.
How much money did John earn over a nine week term?

After 9 weeks, John had $378 in his jar. What percentage of his money did he save?

Answer:

He earns $540

70% of his money went to savings

Step-by-step explanation:

9 weeks x 5 days a week = 45 days

45 days x $12 a day = $540

378 * 100 / 540 =  (378*100) / 540 =  37800/540 = %70

Which is the equation of a circle with center (-2, 3) and radius r = 5?
Arisa [49]

Answer:

(x+2) ^2 + (y-3)^2 = 25  

Step-by-step explanation:

The equation of a circle is given by

(x-h) ^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x--2) ^2 + (y-3)^2 = 5^2

(x+2) ^2 + (y-3)^2 = 25

What is the difference between a relation
taurus [48]

Answer:

Not all relationships are functions, but all functions are also relationships

Step-by-step explanation:

A relationship is a correspondence between two sets of values.

A relationship assigns values from an output set called range to a set and input called a domain.

On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).

In other words, if an input value x_1 is assigned two or more output values y_1, y_2, y_3 .. then the relationship is not a function. This means that <em>not all relationships are functions</em>.

y=\±\sqrt{x} +3   is a relation but it is not a function.

because when x = 4 then y = 1 and y = 5.

Not all relationships are functions, but all functions are also relationships

15) If the point (6, 3) is rotated 180° clockwise about
dalvyx [7]

Answer:

B. (-2, 15)

Step-by-step explanation:

Pretend that your fixed point [2, 9] is at the origin for now by translating it two units <em>west</em><em> </em>then nine units <em>south</em><em> </em>[0, 0]. Now, the same goes for [6, 3]. Translate it two units <em>west</em> then nine units <em>south</em><em> </em>to get [4, -6]. Then, according to the <em>180°-rotation rule</em>, you take the OPPOSITE of both the x-coordinate and y-coordinate:

[4, -6] → [-4, 6]

Now, that you have your rotated point, we have to shift EVERYTHING BACK to the way it was from when we shifted the fixed point of [2, 9] to the origin. We do that by translating everything in reverse order, which is 9 blocks <em>north</em><em> </em>then 2 blocks <em>east</em>:

→ [0, 0] back to [2, 9]

Translation

→ [-4, 6] to the new coordinate of [-2, 15]

I am joyous to assist you anytime.
