Answer 1

Answer: Hello,
In a Venn 's diagram: A={Custumer edu},B={french}, U=the class.

#(A\B)=22-2=20
#(B\A)=20-2=18
#(A∩B)=2
#U=80

p=(20+2+18)/80=20/40=1/2

Answer C (11/40+1/4-1/10=20/40=1/2)

Sorry for the mistake.

Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?

Answers

The total amount she spent is equal to the sum of the amount for food and hotel accommodation. Letting x be the percent tax that Tracy was charged for his food, the equation that best represent the given is,
280.74 / 3 = 49 + (0.10)(49) + 32 + (0.15)(32) + (x)(32)
The value of x from the equation is 0.09. Thus, Tracy is charged 9% tax on his food.

How do i identify the slope,y intercept,x intercept, and zero on a graph

Answers

To find the slope of a line, you need to find the change in x over the change in y, or rise over run. You can do this by taking two points and using the formula $(y_(2) -y_(1))/(x_(2) -x_(1))$ .

To find the y-intercept, find where the graph touches the y-axis.

To find the x-intercept, find where the graph touches the x-axis.

Zeroes on a graph are the same as its x-intercepts.

If 3/2+x/3=11/6,find x .

Answers

Answer:

x = 1

Step-by-step explanation:

3/ 2 + x/ 3 = 11/ 6

taking LCM

(9 + 2x)/ 6 = 11/ 6

multpiying both sides by 6

9 + 2x = 11

subtracting btih sides by 9

2x = 11 - 9

2x = 2

dividing both by 2

x = 1

Step-by-step explanation:

$(3)/(2) + (x)/(3) = (11)/(6)$

$(x)/(3) = (11)/(6) - (3)/(2)$

$(x)/(3) = (11 - 3 * 3)/(6)$

$(x)/(3) = (11 - 9)/(6)$

$(x)/(3) = (2)/(6)$

$(x)/(3) = (1)/(3)$

$x = (3 * 1)/(3)$

$x = 1$

Solve the system using multiplication for the linear combination method.6x – 3y = 3
–2x + 6y = 14
What is the solution to the system?
(2, 1)
(2, –3)
(2, –1)
(2, 3)

Answers

If you would like to solve the system of equations, you can calculate this using the following steps:

6x – 3y = 3
–2x + 6y = 14 /*3
_________
6x – 3y = 3
–6x + 18y = 42
_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3

6x – 3y = 3
6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2

(x, y) = (2, 3)

The correct result would be (2, 3).

The equation of a line is x + 5y = 12. What is the y-intercept of the line? a. 12 b. 512 c. 125 d. −12

Answers

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + 5y = 12 ( subtract x from both sides )

5y = - x + 12 ( divide through by 5 )

y = - $(1)/(5)$ x + $(12)/(5)$ ← in slope- intercept form

with y- intercept c = $(12)/(5)$

What is 6/25 as a percentage

Answers

6/25 as a percentage is 24%.

Commonly, to change a fraction into its percentage form, you would multiply the numerator (the top number) and the denominator (the bottom number) by 100, which is a numerical number that is used.

So, in this case, we would divide:

6/25 × 100

After calculating that, you should know that it equals 24. That should be our answer to solving 6/25 as a percentage.

Also, if you did not know how to simplify the problem:

$(6)/(25) * 100 \n \n (600)/(25) = 24 \n \n$

You basically just focus on the numerator being multiplied by the whole number (which is 100), so 6 multiplied by 100 equals 600, and that is the new numerator. The next step would to be to simplify it by solving what multiples by 25 to get the result of 600. 24 times 25 equals 600...so 24 is the answer.
