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

write the possible range of the measurement 214 ounces +1.2% round to the nearest hundredth if necessary

Answers

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.

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.)

Answers

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.

WILL MARK BRAINLIEST Every month Jordan puts $14 into her bank account. Her grandma puts additional money into Jordan's bank account every month. After 12 months, Jordan has $216 in her bank account. How much did Jordan's grandma put into the account each month?

Answers

Jordan puts 14 per month for 12 months:

14 x 12 = 168 total.

Subtract the amount Jordan put in from the total:

216 - 168 = 48

Her grandma put a total of 48 in the bank. Divide that by 12 months:

48/12 = 4

Her grandma put $4 per month in the bank.

Answer:

The answer is his grandma puts $4 in per month.

Step-by-step explanation:

Take 14 and multiply it buy how many months are in a year. That equals 168. take 216 minus 168. That's 48. Divide 48 by 12 and that gets you 4. I hope this helps!

The temperature on Monday was 16.3 degrees and on Tuesday it was 3 degrees colder. What was the temperature on Tuesday?

Answers

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.

b. What is the probability a player who buys one ticket will win the $10,000 prize?

Answers

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!(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]

Can the lengths 40, 60, and 80 form a supplementary triangle?

Answers

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.
