A Canadian dollar is worth about $0.85 in

Both of them can complete 7/12 of the job in  2 hours.

Rate is the mathematical term use to show how one quantity varies with a standard quantity.

Analysis:

If He can do the job in 8 hours, then he can do 1/8 of the job in 1 hour

If his friend can do the same job in 6 hours, then he can do 1/6 of that job in 1 hour.

So both of them would do the same job combine in 1 hour = 1/8 + 1/6

LCM of 6 and 8 is 24 so that 3/24 + 4/24 = 7/24

In 2 hours they would complete = 7/24 x 2 = 7/12

In conclusion, both of them can do 7/12 of that job in  2 hours.

Answer:

volume of water in the tank when it its half full

The capacity of the water tank = (5.04) /2 = 2.52 m³

2,520 litres

Step-by-step explanation:

Dimensions of a water tank:

Length (l) = 2.0 m,

wide (w) = 1.4 m,

Depth (h)= 1.8 m,

Volume of the tank (V)

LWH

2.0m × 1.4m × 1.8 m

= 5.04 m³

= 5.04 × 1000 litres

/* 1m³ = 1000 litres */

5,040 litres

Therefore,

The capacity of the water tank = 5.04 m³

5,040 litres

Answer: C.) 4/27

Step-by-step explanation:

Given that:

One out of three cards is a winner :

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

(2/3) × (2/3) × (1/3)

4 / 27

Probability of first winning on third try = 4/27

Answer:

495 students

Step-by-step explanation:

The 4 part of the ratio is the number of boys.

Divide the number of boys by 4 to find the value of one part of the ratio.

220 ÷ 4 = 55 ← value of 1 part of the ratio, thus

5 parts = 5 × 55 = 275 ← number of girls

Number of students = 220 + 275 = 495

Answer:

Step-by-step explanation:

[tex]220 \: boys \\ 4:5 = 4 + 5 \\ boys \: = \frac{4}{9} \times x = 220 \\ = \frac{4x}{9} = \frac{220}{1} [/tex]

Answer:

$27.14

Step-by-step explanation:

Given the following :

Discount on Jean:

20% off the original price = (100 - 20) × original price = (80% × original)

Original price = $32

Sales price after discount :

(80/100) × $32

0.8 × $32

= $25.6

Tax fee on sales price :

Tax rate = 6%

(6/100) × $25.6

0.06 × $25.6 = $1.536

Therefore, final cost of the Jean ;

Discounted price + tax fee

$25.6 + $1.536

= $27.136

= $27.14

Answer:

B.

[tex]y = - x + 2[/tex]

Answer:

b. y=-x+2

Step-by-step explanation:

hi!

the slope intercept form is y=mx+b where m is the slope, and b is the y intercept.

since the y intercept is postive 2, we can first eliminate choices A and C since they show a y intercept of negative 2, not positive 2.

next, we can eliminate d since the line of the graph is going downwards, meaning that the slope or m is negative.

Therefore, the correct answer is b.

u can also use a graphing calculator if youre unsure and plug in each equation and see if it matches with the graph.

Answer: C

Step-by-step explanation:

C) All four sides are congruent

A rectangle does not have all four sides that are congruent to each other (In harmony) however a square does because all it's sides are equal!

A rectangle does not have equal sides, only it's parrel sides are equal to each other.

Answer:

x=35

Step-by-step explanation:

Since a quadrilateral's interior angles add up to 360°, we get this:

360-85-20=360-4x+x

340-85=360-3x

255=360-3x

-105= -3x

Multiply both sides by -1

105=3x

3x=105

Divide both sides by 3

x=35

Answer:

Option D. 91/4950

Step-by-step explanation:

The following data were obtained from the question:

Barcelona (B) = 23

Real Madrid (R) = 23

Liverpool (L) = 22

Manchester City (M) = 18

Juventus (J) = 14

Total (T) = 100

Next, we shall determine the probability of the first pick i.e probability of Juventus. This is illustrated below:

P(J1) = n(J) /n(T)

P(J1) = 14/100

Now, the picking is done without replacement. The next pick being Juventus will reduce in number and likewise the total number will also reduce i.e

Juventus = 13

Total = 99

Therefore, the probability that the 2nd pick is Juventus is given below:

P(J2) = 13/99

Now, we can obtain the probability that the 1st and 2nd student prefer Juventus as follow:

P(J1 and J2) = P(J1) x P(J2)

P(J1) = 14/100

P(J2) = 13/99

P(J1 and J2) = P(J1) x P(J2)

P(J1 and J2) = 14/100 x 13/99

P(J1 and J2) = 7/50 x 13/99

P(J1 and J2) = 91/4950

Therefore, the probability that the 1st and 2nd student prefer Juventus is 91/4950

Answer:

Step-by-step explanation:

Answer:

C). y = ln x + 4

Step-by-step explanation:

First off, we can cancel out the [tex]e^{x}[/tex] graphs.

Now looking at the graph, one can see that when x = 1, y = 4.

So for each [tex]ln[/tex] function, plug in 1 for x.

In doing this, one will find that y = ln x + 4 is the only [tex]ln[/tex] graph that produces 4 when x = 1.

Answer: The radius and the cord must be perpendicular to each other.

Step-by-step explanation:

A cord is a line from a point of circumference of a circle to another point of the circumference of the circle without passing through the centre.

A radius is a line from the centre of a circle to the circumference of the circle.

When the radius line intersect and bisects a cord of a circle, the radius and the cord must be perpendicular to each other.

Answer:

if in a circle a radius bisects a chord then the radius is perpendicular to the chord,

Step-by-step explanation:

4.825-0.145=4.68 in

The inside diameter of the pipe is 4.68 inches.

A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.

Given:

The outside diameter of a pipe is 4.825 inches.

If the pipe wall is 0.145 inches thick,

the inside diameter of the pipe,

= 4.825 - 0.145

= 4.68

Therefore, the diameter is 4.68 inches.

Answer:

v = -23/4 = -5 3/4

Step-by-step explanation:

4= - 3/(v+5)

Multiply each side by (v+5)

4 (v+5) = -3

Distribute

4v+20 = -3

Subtract 20 from each side

4v +20-20 = -3-20

4v = -23

Divide by 4

4v/4 = -23/4

$400 is the principal, 0.03 is the decimal value for the annual rate, and the time is 1 year.

Answer:

One half of X are employees.

One third of X are employee's spouses.

We add one half PLUS one third:

1/2 + 1/3 = 3/6 + 2/6 = 5/6

Then we subtract that fraction from one whole, or 1,

to see what fraction is left.  That is, we say

1 minus 5/6

which is

1 - 5/6

Now write 1 as 6/6

6/6 - 5/6

We get 1/6

So 1/6 is left.  Now we need to make that into

a percent by multiplying it by 100 and tacking on a "%"

1/6 � 100

1/6 � 100/1

100/6

50/3

16 2/3 %

So 16 2/3 % of the people in

attendance are neither employees

nor employee's spouses.

Now let's check:

1/2 are employees.  That's 50%

1/3 are wmployee's spouses. That's 33 1/3%

15 2/3 % are neither employees nor employee's spouses.

Add them up

50     %

33 1/3 %

16 2/3 %

--------

99 3/3 %

And 99 3/3% = 100%
