What is the answer to this
Answer: C. 124
Step-by-step explanation:
In parallelograms, any two consecutive interior angles add to 180 degrees. CDA and BCD are consecutive interior angles. Since the measure of angle CDA is 56 and the sum of CDA and BCD equal 180, then to find the value of BCD, evaluate 180-56.
180 - 56 = 124

Can the lengths 40, 60, and 80 form a supplementary triangle?
Answer: Yes
Step-by-step explanation:
A supplementary triangle has sides adding up to 180°.
We have the side lengths 40, 60, and 80.
To find out if it is a supplementary triangle, we will add all the sides.
40 + 60 + 80 = 180
We get 180° as our answer when we add.
We got 180°, so the answer is yes, it can.
Best of Luck!
Answer:
yes.
Step-by-step explanation:
Any angle that adds up to 180 is a supplementary angles.
based on your examples 40, 60, 80, if you sum it up...
it equates to 180. so the answer is yes.

In a certain state's lottery, 40 balls numbered 1 through 40 are placed in a machine and 7 of them are drawn at random. If the 7 numbers drawn match the 7 numbers a player has chosen, in any order, she or he win $2,500,000. Alternatively, if 6 of the numbers drawn match 6 of the 7 numbers a player has chosen, in any order, the player wins $40,000, and if 5 of the numbers drawn match 5 of the 7 numbers a player has chosen, in any order, the player wins $10,000.
Required:
a. What is the probability a player who buys one ticket will win the $2,500,000 prize?
b. What is the probability a player who buys one ticket will win the $10,000 prize?
Answer:
Step-by-step explanation:
From the given information;
The total number of ways to choose 7 number = [tex]^{40}C_7[/tex]
Number of ways to choose 7 correct numbers = [tex]^{7}C_7[/tex]
∴
The probability P( win $2500000) is;
[tex]= \dfrac{^{7}C_7}{^{40}C_7}[/tex]
[tex]= \dfrac{\dfrac{7!}{7!(7-7)!} }{\dfrac{40!}{7!(40-7)!}}[/tex]
[tex]= \dfrac{1 }{\dfrac{40!}{7!(40-7)!}}[/tex]
[tex]= \dfrac{1 }{\dfrac{40!}{7!(33)!}}[/tex]
[tex]= \dfrac{1 }{18643560}[/tex]
= 5.36 × 10⁻⁸
The probability P( win $10000) is:
[tex]= \dfrac{^7C_5 \times ^{33} C_2}{^{40}C_7}[/tex]
[tex]= \dfrac{ \dfrac{7!}{5!(7-5)!} \times \dfrac{33!}{2!(33-2)!} }{ \dfrac{40!}{7!(40-7)!}}[/tex]
[tex]= \dfrac{ \dfrac{7!}{5!(2)!} \times \dfrac{33!}{2!(31)!} }{ \dfrac{40!}{7!(33)!}}[/tex]
[tex]= \dfrac{ 21 \times 528 }{ 18643560}[/tex]
[tex]= \dfrac{ 11088 }{ 18643560}[/tex]
[tex]=\dfrac{462}{776815}[/tex]

A basketball is thrown upward from a height of 1.8 m at a velocity of 12 m/s. How long until it reaches the ground?
(Recall: h(t)=-4.9t^2-v_0 t+h_0, where v_0 is initial velocity and h_0 is initial height.)
Answer:
Step-by-step explanation:
The quadratic is
[tex]s(t)=-4.9t^2+12t+1.8[/tex]
where s(t) is the height of the ball after a certain amount of time goes by. If we are looking for how long til it hits the ground, we know 2 things from that question. First we know that the height of an object on the ground is 0, and we also know that t is the time that the ball is in the air. Because the height of the ball when it's on the ground is 0, we will set s(t) equal to 0 and factor the quadratic to solve for t, the time the ball is in the air. Throw it into the quadratic formula to find those times.
[tex]t=\frac{-12+/-\sqrt{144-4(-4.9)(1.8)} }{2(-4.9)}[/tex] which will simplify to
[tex]t=\frac{-12+/-\sqrt{179.28} }{-9.8}[/tex]
The 2 solutions we get from that are that
[tex]t=\frac{-12+\sqrt{179.28} }{-9.8}=-.1417906 sec[/tex] and
[tex]t=\frac{-12-\sqrt{179.28} }{-9.8}=2.59077sec[/tex]
Now, the 2 things in math that will never be negative are distances and time, so we will disregard the negative time and go with t = 2.59 seconds. Not sure to where you need to round.
Brad works in the sales department for a furniture store. He earns a salary of $2,500 a month and a 3% commission if he meets his quota of $10,000 in sales for the month.

10(-2.5)(-4) what is the answer plz explain
Answer:
100
Step-by-step explanation:
10(-2.5) = -25 since negative times positive is negative.
-25(-4)=100 since negative times negative is positive.
Basically, the negative inverts the sign so a negative negates a positive yielding a negative while a negative negates a negative yielding a positive.

The temperature on Monday was 16.3 degrees and on Tuesday it was 3 degrees colder. What was the temperature on Tuesday?
Answer:
The temperature on Tuesday was 13.3 degrees Celcius, 3 degrees less than that of Monday.
Step-by-step explanation:
Given that the temperature on Monday was 16.3 degrees Celsius, and the following Tuesday the temperature dropped about 3 degrees, to determine the temperature of that day the following calculation must be made:
16.3 - 3 = X
13.3 = X
Thus, the temperature on Tuesday was 13.3 degrees Celcius, 3 degrees less than that of Monday.
write the possible range of the measurement 214 ounces +1.2% round to the nearest hundredth if necessary
9514 1404 393
Answer:
[211.43,216.57]
Step-by-step explanation:
1.2% of 214 is ...
0.012 × 214 = 2.568 ≈ 2.57 . . . . rounded to hundredths
Then the minimum possible value is ...
214 -2.57 = 211.43
and the maximum possible value is ...
214 +2.57 = 216.57
The range is 211.43 to 216.57.
