Answer:
BD>DA>AB
Step-by-step explanation:
Since ACB = 60, ACD = 120. Since ACD>ACB then DA is greater than AB. Then we can see that AC + DC has to be greater than DA because of triangle property theorem. That's the same as BC + CD by transitivity and BC + CD is BD by PWP. That means that BD > DA. Since we know that BD > DA, we can say, BD > DA > AB.

Answer:
158.76 square centimeters
Step-by-step explanation:
The quadrilateral is made up of 2 right triangles if you divide the quadrilateral using line segment BD.
The triangle on the bottom has an area of 11.7*15.6/2, which is 91.26.
The triangle on the top has an area of 7.5*18/2, which is 67.5.
If you add up the area of these 2 triangles, you get 67.5 + 91.26 = 158.76
Therefore, the answer is 158.76 square centimeters.
I hope this helped you.

18) The school that John goes to is selling tickets to the annual talent show. On the first day of ticket
sales the school sold 3 senior citizen tickets and 5 student tickets for a total of $71. The school
took in $190 on the second day by selling 10 senior citizen tickets and 12 student tickets. Find
the price of a senior citizen ticket and the price of a student ticket.
Answer:
Student ticket=$10. Senior ticket=$7
Step-by-step explanation:
If we say Student ticket price = Y. and senior ticket price = X. Then we can say:
[tex]3x+5y=71\\10x+12y=190[/tex]
We can rewrite one of the equations as y equals:
[tex]10x=190-12y[/tex]
Then, we simply solve for x.
[tex]\frac{10x=190-12y}{10}=x=19-1.2y[/tex]
Then, we use the other equation and replace x with the equation we just solved
[tex]3(19-1.2y)+5y=71\\[/tex]
We simplify and it becomes:
[tex]57-3.6y+5y=71[/tex]
Then we subtract 57 from each side and get:
[tex]-3.6y+5y=-14[/tex]
Next, we combine the y and get:
[tex]1.4y=14[/tex]
Then we divide by 1.4 and get:
[tex]\frac{1.4y=14}{1.4} =y=10[/tex]
This means that the cost per student ticket is $10
Next we replace the y value in an equation with 10 and solve:
[tex]3x+5y=71\\3x+5(10)=71\\3x+50=71\\[/tex]
Then we subtract 50 from each side:
[tex]3x+50=71\\-50\\3x=21[/tex]
Finally, we divide each side by 3:
[tex]\frac{3x=21}{3} =x=7[/tex]
This means that each senior ticket costs $7
Using this and the knowledge that 32° F = 0°C and 212°F = 100°C, find an equation that computes Celsius temperature in terms of Fahrenheit temperature; i.e., an equation of the form C = “an expression involving only the variable F.”
c=(f-32)/1.8
Likewise, find an equation that computes Fahrenheit temperature in terms of Celsius temperature; i.e. an equation of the form F = “an expression involving only the variable C.”
f=1.8c+32
(a) How cold was it in Oslo in °F?
(b) What temperature is it the same in °F and °C?
Answer:
(a)
Step-by-step explanation:
The relationship between temperatures measured in Fahrenheit, and in Celsius can be represented using equations.
The equations are: [tex]F = 1.8C + 32[/tex] and [tex]C = \frac{(F - 32)}{1.8}[/tex].The temperature in Oslo is [tex]60.8^oF[/tex].[tex]-40^oF[/tex] is equivalent to [tex]-40^oC[/tex]Given that:
[tex](F_1,C_1) = (32,0)[/tex]
[tex](F_2,C_2) = (212,100)[/tex]
First, calculate the slope (m)
[tex]m = \frac{C_2 - C_1}{F_2 - F_1}[/tex]
So we have:
[tex]m = \frac{100 - 0}{212 - 32}[/tex]
[tex]m = \frac{100}{180}[/tex]
[tex]m = \frac{5}{9}[/tex]
So, the equation is calculated using:
[tex]C= m(F - F_1) + C_1[/tex]
So, we have:
[tex]C = \frac 59(F - 32) + 0[/tex]
[tex]C = \frac 59(F - 32)[/tex]
Rewrite as:
[tex]C = \frac{(F - 32)}{9/5}[/tex]
[tex]C = \frac{(F - 32)}{1.8}[/tex]
To solve for F, we multiply both sides by 1.8
[tex]1.8C =F - 32[/tex]
Add 32 to both sides
[tex]F = 1.8C + 32[/tex]
(a) The temperature of Oslo in F
We have:
[tex]C = 16[/tex]
So, we make use of:
[tex]F = 1.8C + 32[/tex]
[tex]F = 1.8 \times 16 + 32[/tex]
[tex]F = 60.8[/tex]
The temperature in Oslo is [tex]60.8^oF[/tex]
(b) When F = C
We have:
[tex]F = 1.8C + 32[/tex]
Substitute F for C
[tex]F = 1.8F +32[/tex]
Collect like terms
[tex]F - 1.8F =32[/tex]
[tex]-0.8F =32[/tex]
Make F the subject
[tex]F = \frac{32}{-0.8}[/tex]
[tex]F = -40[/tex]
Hence,
[tex]-40^oF[/tex] is equivalent to [tex]-40^oC[/tex]

Step-by-step explanation:
Suppose a firm loses $4,000 in its first month, but increases its profit by $575
each month for the first year. Find the firm's total profit or loss in the first
year.
O Loss of $10,050
O Loss of $2,250
O Profit of $2,325
O Profit of $85,950
Answer:
profit of $2325
Step-by-step explanation:
so a loss of $4000 in the first month, with profit of $575 each month. let's say a year have 12 months, first month with loss, the other 11 months with profit. so, $575 x 11 months = $6325. $6325 is the amount for 11 months with $575 profit. take $6325 and minus with $4000 and you will get $2325, which is the profit for the first year.

Given z=-4-6i
Write down the conjugate of z
Answer:
z = -4 + 6i
Step-by-step explanation:
A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x+y is x−y . We can also say that x+y is a conjugate of x−y . In other words, the two binomials are conjugates of each other.

suppose y varies directly with x, and y=24 when x= 8. What is the value of y ehen x= 10
Answer: 30 = y
Step-by-step explanation: When we have two sets of directly related coordinates, x₁ and y₁, and x₂ an y₂, we can use the ratio below to find the missing value.
y₁ / x₁ = y₂ / x₂
We know that y = 24 when x = 8.
So one set of coordinates will be 24 and 8.
We want to know the value of y when x = 10.
So the other coordinates will be y and 10.
So we have 24/8 = y/10.
Now, we can solve for y using cross products.
So we have (24)(10) which is 240 and (8)(y) is 8y.
So we have 240 = 8y.
Now dividing both sides by 8, we have 30 = y.
So 30 is equal to y.

The mean gas mileage for cars driven by the students at Chillville High School is 28.0 miles per gallon, and the standard deviation is 4.0 miles per gallon. Assume that the gas mileages are normally distributed.
What percent of the cars driven by the students at Chillville have gas mileages between 24.0 and 32.0 miles per gallon?
68%
95%
32.8%
34%
Using the Empirical Rule, it is found that 68% of the cars driven by the students at Chillville have gas mileages between 24.0 and 32.0 miles per gallon.
What is the Empirical Rule?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, considering the mean of 28 mpg and the standard deviation of 4 mpg, we have that 24.0 and 32.0 mpg is within 1 standard deviation of the mean, hence the percentage is of 68%.
