How many real solutions does the equation 8x^2 − 10x + 15 = 0 have?
Answers
Answer:
It has no real solutions.
Step-by-step explanation
Once you calculate the discriminant, D= (-10)^2 -4 (8)(15), you simplify the expression to get D= -380, which has no real solutions.
Answer:
No solutions
Step-by-step explanation:
Quadratic equations are in the form of ax^2+bx+c, so a = 8, b= -10, and c = 15.
Use b^2 - 4ac to find the discriminant.
-10^2 - 4(8)(15) = -580
If a discriminant is < 0 then there are no real solutions to a quadratic equation. -580 < 0
Therefore, there are no real solutions

Answer:
1). Number of kids on the other side = 16
2). Brian took the time to each piece of pie = 20 seconds
Step-by-step explanation:
1). Let the number of kids on one side = x
Then the number of kids on other side = 2x
3 adults helped the side having number of kids = x, then the number of people on this side = x + 3
Since the total number of people on this side = 11
Then the equation will be,
x + 3 = 11
x = 11 - 3
x = 8
Then number of kids on the other side = 2x = 2×8
= 16
2). By unitary method,
∵ Brian took the time to eat 6 pieces of the pie = 2 minutes
∴ Brian will take time to eat 1 piece of pie = [tex]\frac{2}{6}[/tex] minutes
= [tex]\frac{2}{6}\times 60[/tex] seconds

The area of triangle is 1/5 feet².
Step-by-step explanation:
You have to use area of triangle formula, A = 1/2×height×base. Then substitute the following values into the formula :

Let height = 3/5,
Let base = 2/3,
[tex]area = \frac{1}{2} \times \frac{3}{5} \times \frac{2}{3} [/tex]
[tex]area = \frac{1}{2} \times \frac{1}{5} \times \frac{2}{1} [/tex]

The number of State Parks in California is 36 more than one third the number of State Parks in Florida. There are 85 State Parks in California. Which of the following equations would you use to find the number of State Parks in Florida? Note: f represents the number of state parks in Florida
Answers
Answer:
number of state parks in Florida is 147.
Equation is 1/3(f) + 36 = 85
Step-by-step explanation:
Given that f represents the number of state parks in Florida.
Also given that number of State Parks in California is 36 more than one third the number of State Parks in Florida
number of State Parks in California = 1/3 (number of State Parks in Florida) + 36
but it is given that There are 85 State Parks in California
and f represents the number of state parks in Florida
85 = 1/3(f) + 36 _________equation
=> 85 - 36 = 1/3 (f)
=> 49 = 1/3 f
=> 49*3 = f
=> f = 147
Thus, number of state parks in Florida is 147.
Equation is 1/3(f) + 36 = 85

Ivan and Polina have each drawn a conclusion about multiplying negative fractions. Ivan: The product of an even number of negative fractions is always positive. Polina: The product of an odd number of negative fractions is always negative. Whose conclusion is correct?
Answers
Answer:
Both conclusions are correct
Step-by-step explanation:
Ivan: The product of an even number of negative fractions is always positive.
When even numbers of same negative fractions are multiplied together, the product is positive.
For instance: -1 × -1
Since the total numbers to be multiplied are even (two -1), the product becomes +1
Ivan's conclusion is correct.
Polina: The product of an odd number of negative fractions is always negative.
When odd numbers of same negative fractions are multiplied together, the product is negative.
For instance: -1 × -1 × -1 × -1 ×-1
Since the total numbers to be multiplied are odd (five -1), the product becomes -1
(-1 × -1) × (-1 × -1) ×-1
= +1 × +1 × -1
The multiplication of same sign gives positive value while the multiplication of two different signs gives a negative value
= +1 × -1
= -1
Polina's conclusion is correct
Both are correct.

Irrational numbers: Decimal numbers that are not represented by patterns, that is, for example, 0.1033430290339. Real numbers: Rational plus irrational.----------------------------------
-5 is a negative number, so it is integer.All integers are rational and real, and thus, -5 is integer, rational and real.A similar problem is given at https://brainly.com/question/10814303
