I have one more Brainliest

Tresset [83]

Okay, so we need to find the price of the original shirt and the discounted shirt with the 5% tax.

5% (into a real number) is .05

Multiply 20.98 and 15.48 by .05

20.98*.05= 1.049 I am going to round to 1.05

15.48*.05= 0.774 I am going to round to .75

Now we know the prices of both, so we subtract them by each other.

20.98+1.05= 22.03
15.48+.75= 16.23

22.03-16.23= 5.80

But since we rounded the numbers, I would go with choice D.

Hope this helps!

The ratio between the number of red and green marbles in a box is 3:7. How many marbles are in the box if there are 20 fewer red

jeyben [28]

Answer:

50 marbles

Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.

4 units = 20

1 unit = 20÷4 = 5

Total = 10 units

10 unit = 5 ×10 = 50

Ans : 50 marbles

Given x² - 16x + 4 = 0:

arsen [322]

PART A
General formula of quadratic equation
ax² + bx + c = 0
To find the discriminant of the quadratic equation shown above, use this following formula.
d = $\sqrt{b^{2}-4ac}$

There is a quadratic equation below
x² - 16x + 4 = 0
therefore
a = 1
b = -16
c = 4

Plug in the numbers to the formula
d = $\sqrt{b^{2}-4ac}$
d = $\sqrt{(-16)^{2}-4(1)(4)}$
d = $\sqrt{(256-16}$
d = $\sqrt{240}$

Simplify
d = $\sqrt{16*15}$
d = $4 \sqrt{15}$
The value of the discriminant is 4√15

PART B
If the discriminant is less than zero (negative), the quadratic equation has imaginary solution.
If the discriminant is equal to zero, the quadratic equation has only one solution.
If the discriminant is more than zero (positive), the quadratic equation has two real solutions.

Because the discriminant of the quadratic equation is 4√15 and it's positive, <u>the quadratic equation has two real solutions.</u>

Yes because you are moving both the 120 for the clockwise and another 120 to get all the the way around from the counter part of counterclockwise
