Divide 33 by 4, which is 8. Now do 8 times 7. 7 is the hours and 8 is the cost per hour, which is why me multiply. 8 times 7 = 56. Hope this helps

Can someone help me please and fast

1)
Worked out for 6 days

During each workout he rode his bike for 45 minutes

6 days x 45 mins
= 270 minutes

2) To find the amount of time that he jogged, you do:
Total - time spent biking = time spent jogging

360 mins - 270 mins
= 90 minutes spent jogging

3) To find out how much time he spent jogging each day you do:
Time spent jogging / days worked out

90 mins / 6 days
= 15 minutes

He jogged 15 minutes a day

Hope this helped!

How many equivalence relations are there on the set 1, 2, 3]?

Alex787 [66]

Answer:

We need to find how many number of equivalence relations are on the set {1,2,3}

A relation is an equivalence relation if it is reflexive, transitive and symmetric.

equivalence relation R on {1,2,3}

1.For reflexive, it must contain (1,1),(2,2),(3,3)

2.For transitive, it must satisfy: if (x,y)∈R then (y,x)∈R

3. For symmetric, it must satisfy: if (x,y)∈R,(y,z)∈R then (x,z)∈R

Since (1,1),(2,2),(3,3) must be there is R, (1,2),(2,1),(2,3),(3,2),(1,3),(3,1). By symmetry,

we just need to count the number of ways in which we can use the pairs (1,2),(2,3),(1,3) to construct equivalence relations.

This is because if (1,2) is in the relation then (2,1) must be there in the relation.

the relation will be an equivalence relation if we use none of these pairs (1,2),(2,3),(1,3) . There is only one such relation: {(1,1),(2,2),(3,3)}

we can have three possible equivalence relations:

{(1,1),(2,2),(3,3),(1,2),(2,1)}

{(1,1),(2,2),(3,3),(1,3),(3,1)}

{(1,1),(2,2),(3,3),(2,3),(3,2)}

Rewrite in a simpler equivalent form and solve

AveGali [126]

Given:

The equation is

$\dfrac{3x}{7}+\dfrac{2}{7}=2$

To find:

The simpler equivalent form and solve the given equation.

Solution:

We have,

$\dfrac{3x}{7}+\dfrac{2}{7}=2$

It can be written as

$\dfrac{3x+2}{7}=2$

Multiply both sides by 7.

$3x+2=14$

$3x=14-2$

$3x=12$

Divide both sides by 3.

$x=\dfrac{12}{3}$

$x=4$

Therefore, the simpler equivalent form of the given equation is $3x+2=14$ and the solution is x=4.

What is the exact value of the expressions the square root of 180 - the square root of 125 + the square root of 5? Simplify if p

Paraphin [41]

So for this, we will be simplifying √180 and √125 using the product rule of radicals (√ab = √a * √b)

Starting with √180: $\sqrt{180}=\sqrt{10} *\sqrt{18} =\sqrt{5} *\sqrt{2}*\sqrt{9} *\sqrt{2}=3*2*\sqrt{5} =6\sqrt{5}$

Now with √125: $\sqrt{125}=\sqrt{25}*\sqrt{5} =5\sqrt{5}$

Now that we have our simplified radicals, our equation looks like this: 6√5 - 5√5 + √5 . Combine everything, and your answer will be 2√5.
