A quadratic equation has exactly one real number solution. Which is the value of its discriminant?
-1
0
1
2
Answers
Exactly one solution means the quadratic is a perfect square, so the usual two solutions coincide. When we have repeated roots that means the discriminant is zero.

Answer:
2y° + x° + y° + 2x° + (180-33)° = 360°
3x + 3y + 147 = 360
3(x+y) = 360 - 147
3(x+y) = 213
x+y = 71
2y + 2x + K = 180
2(x+y) + K = 180
2 *71 + K = 180
142 + K = 180
K = 38°

At lunch, there are 7 cartons of milk sold for every 3 juice boxes sold. If 210 drinks are sold on Friday, how many of those drinks are juice boxes?
THIS IS OVERDUE HELP
Answers
Answer: 63 Juice boxes
Step-by-step explanation: So you know that 7(cartons of milk)+3(juice boxes)= 10 so you divide 210 by 10 and you get 21. 21x3 is 63 so 63 juice boxes are sold. To check the answer i did 21x7 and i got 147. 147+63=210
63 juice boxes and 147 cartons of milk are sold.
Explanation-
7 + 3= 10 (the 7 represents the milk cartons and the 3 represents the juice boxes). Since 210 drinks are sold that means you must divide 210 by 10 (since 10 is the total), when you divide 210 by 10 you get 63. So in conclusion the answer is 63.

7. Danielle went to the grocery store to buy pies for a family dinner.

Is the relationship between the number of pies and the cost proportional? JUSTIFY YOUR ANSWER

Answer:
No
Step-by-step explanation:
The relationship between the number of pies and the cost is not proportional. This is because the third pie is at half price, meaning it's not consistent with the price of the other two.

B 1616

D 1313
E 17
Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:

this will result in 45/4, or 11.25
now, you have to figure out how many small cubes will fit inside prism ll
we know that the side lengths of the small cubes are 1/4, and since cubes have equal side lengths, you can multiply 1/4, 1/4, and 1/4 to find the area
this will result in 1/64
divide the area of prism ll, 11.25, by the area of the small cubes, 1/64, to get 720
then, do the same thing for prism l
multiply 7/4, 3/2, and 5/4 to get 105/32
divide this by the previous 1/64 to get 210
lastly, to determine how many more small cubes can fit into prism ll, subtract 210 from 720
720-210=510
final answer: 510 cubes

15/56 in simplest form
If you get it right I will mark brainly!
Answers
15/56 is already in the simplest form. It can be written as 0.267857 in decimal form (rounded to 6 decimal places).
Steps to simplifying fractionsFind the GCD (or HCF) of numerator and denominator
GCD of 15 and 56 is 1
Divide both the numerator and denominator by the GCD
\(\dfrac{15\div1}{56\div1}\)
Reduced fraction:
\(\dfrac{15}{56}\)
Therefore, 15/56 simplified to lowest terms is 15/56.
Answer:
15/56
Step-by-step explanation:
What is a fraction?A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
To put the fraction 15/56 in its simplest form, you need to find the greatest common divisor (GCD) of the numerator (15) and the denominator (56). The GCD of 15 and 56 is 1. Dividing both the numerator and denominator by their GCD gives us:
\(\frac{15}{1}\) ÷ \(\frac{56}{1}\) = \(\frac{15}{56}\)Therefore, 15/56 is already in its simplest form.
