Answer:

answer is $330

Step-by-step explanation:

If you are ever dealing with percentages always put them into a decimal itll make things a lot easier

how you do that is 55/100 which is 0.55

then just multiply by the original number

0.55 times 600 which is 330

on the coordinate plane, what is the length of the line segment that connects points at (5, 4) and (−3, −1) ? Enter your answer

gtnhenbr [62]

Distance between points
D= $\sqrt{(y2-y2)^2+(x2-x1)^2}$
<span>
points are (5, 4) and (−3, −1)
</span>
D=√(-1-4)^2+(-3-5)^2
D=√25+64
D=√89
D=9.433 units

If discriminant (b^2 -4ac>0) how many real solutions

MaRussiya [10]

Answer:

If Discriminant, $b^{2} -4ac >0$

Then it has Two Real Solutions.

Step-by-step explanation:

To Find:

If discriminant (b^2 -4ac>0) how many real solutions

Solution:

Consider a Quadratic Equation in General Form as

$ax^{2} +bx+c=0$

then,

$b^{2} -4ac$ is called as Discriminant.

So,

If Discriminant, $b^{2} -4ac >0$

Then it has Two Real Solutions.

If Discriminant, $b^{2} -4ac < 0$

Then it has Two Imaginary Solutions.

If Discriminant, $b^{2} -4ac=0$

Then it has Two Equal and Real Solutions.

Chris pays a fee if her balance falls below $10 on the statement data. Prior to the statement date, her balance was -$3.46. Then

alisha [4.7K]

Answer:

The solution of the inequality required for the situation is d ≥ $13.46.

Step-by-step explanation:

i) the minimum deposit is $10.

ii) the balance before the statement is $-3.46

iii) a deposit d is made so that the fee did not have to be made

iv) therefore d + (-3.46) ≥ 10

d - 3.46 ≥ 10

therefore d ≥ 10 + 3.46

therefore d ≥ $13.46
