Answer:
5% sales-tax rate was she charged for this blazer
Step-by-step explanation:
As per the statement:
Jan bought a blazer for $39.90.
The price of the blazer was $38.
Sales tax price = 39.90 - 38 = $1.90
We have to find the sales-tax rate was she charged for this blazer percentage wise.
Using formula:
Substitute the given value we have;
Therefore, 5% sales-tax rate was she charged for this blazer percentage wise
arrive at his destination in 5 minutes. The teacher knows
he will need to save 30 seconds to pack up his materials.
What is the maximum number of exit tickets that he can
grade?
A) 8
B) 7
C) 6
D) 5
Answer:
6 papers
Step-by-step explanation:
5 minutes = 5 * 60 = 300 seconds
He needs to save 30 seconds
300 - 30 = 270 seconds
270 seconds / 42.5 seconds per paper

The two figures that multiply to-48 and add up to-2 are-8 and 6.
Let's assume the two figures are x and y.
According to the problem, we've two conditions
x y = -48
x y = -2
To break this, we can rewrite the alternate equation as
x = -2- y
Now substitute this value of x in the first equation
(-2 - y) y = -48
- 2y- y² = -48
Rearranging the terms
y² + 2y- 48 = 0
Now, solving the Quadratic Equation
(y+ 8)( y- 6) = 0
Setting each factor to zero
y + 8 = 0--> y = -8
y- 6 = 0--> y = 6
So we've two possible values for y is -8 and 6.
Substituting these values back into the equation x + y = -2, we can break for x
For y = -8
x(- 8) = -2
x- 8 = -2
x = 6
For y = 6
x 6 = -2
x = -2- 6
x = -8
Thus, the two figures that multiply to-48 and add up to-2 are-8 and 6.

D. 8
Answer:
the answer is -1/ 8
Step-by-step explanation:
(−2−6)(23)
=(−1/64)(2x3)
=−1/64 (2x3)
2x2x2= 8
-1/64 8/8
Now you divide both sides by 8
-1/64 / 8/8= -1/8
So your answer is −1/8(C)
