Answer:
its 25° .
because its an isosceles trangle as jk=kl =7.
and angle J is equal to angle L as they are base angles of an isosceles triangle.
The probability of the spinner landing on a two is three eighths aka 3/8 aka c
Solve the following system:
{1.8 x - 0.5 y = -6.4
{0.6 x + 2.1 y = 2.4
In the first equation, look to solve for x:
{1.8 x - 0.5 y = -6.4
{0.6 x + 2.1 y = 2.4
1.8 x - 0.5 y = (9 x)/5 - y/2 and -6.4 = -32/5:
{(9 x)/5 - y/2 = -32/5
Add y/2 to both sides:
{(9 x)/5 = 1/10 (5 y - 64)
{0.6 x + 2.1 y = 2.4
Multiply both sides by 5/9:
{x = 1/18 (5 y - 64)
{0.6 x + 2.1 y = 2.4
Substitute x = 1/18 (5 y - 64) into the second equation:
{x = 1/18 (5 y - 64)
{2.1 y + 0.0333333 (5 y - 64) = 2.4
2.1 y + 0.0333333 (5 y - 64) = 2.1 y + (0.166667 y - 2.13333) = 2.26667 y - 2.13333:
{x = 1/18 (5 y - 64)
2.26667 y - 2.13333 = 2.4
In the second equation, look to solve for y:
{x = 1/18 (5 y - 64)
{2.26667 y - 2.13333 = 2.4
2.26667 y - 2.13333 = (34 y)/15 - 32/15 and 2.4 = 12/5:
(34 y)/15 - 32/15 = 12/5
Add 32/15 to both sides:
{x = 1/18 (5 y - 64)
{(34 y)/15 = 68/15
Multiply both sides by 15/34:
{x = 1/18 (5 y - 64)
y = 2
Substitute y = 2 into the first equation:
Answer: {x = -3, y = 2
Answer:
The center is at (3,1) and the radius is 
Step-by-step explanation:
I am going to assume you meant to write
Since if both variables were x it would not be a circle:
Then you can find the center and radius using the general formula of a circle:
where the center is at (h,k) and r is the radius
Therefore:
The center is at (3,1) and the radius is
Answer:
46.77
Step-by-step explanation:
First, we need to determine what the final price is for each pair in these two stores. In Super Sports, the shoes were originally $72.50, but they had a 20% discount. This means that you would pay for 80% (0.8) of the price:
72.50 * 0.8 = 58
A 6.5% sales tax will be applied to the discounted price. This means you would pay for 106.5% of the price:
58 * 1.065 = 61.77
On the other hand, at Double Dribble, the shoes are originally $54.75. A 9% processing fee is applied to this:
54.75 * 1.09 = 59.67
plus a shipping fee of $5.99:
59.67 + 5.99 = 65.67
If we were to buy 12 pairs of shoes, the prices would be:
Store A: 61.77 * 12 = 741.24
Store B: 65.67 * 12 = 788.01
The difference would be $46.77 (788.01 - 741.24).
