Step-by-step explanation:
Cost = $112
30% discount coupon on the item he's going to buy
=$112 × 30/100 (or you can write 30%)
=$168/5 ($33.6)
7% tax on the item=$112 × 7/100(or you can write 7%)
= $196/25 ($7.84)
Total amount altogether=$112 - $33.6 - $7.84
=$70.56
not sure for the answer^^
The scale factor of the Reba's drawing is 9/84, 3/28
Step-by-step explanation:
The scale factor is the ratio between the two corresponding sides of the figure. The point worth noting in computing the scale factor is that both sides must have similar units of dimension while using for comparison purpose.
Given the scale used by Reba is 9 inches to 7 feet
Since both the units are different, we have the option to either convert inches to feet or vice versa
We proceed with converting feet to inches
We know that 1 foot equals to 12 inches. Hence 7 feet would equal 84 inches.
Now scale factor= first dimension/ corresponding dimension
Scale factor= 9/84 which can be reduced to 3/28
You need Pythagorean theorem for this.
a² + b² = c², where c is the hypotheneus and a and b are the sides of the right triangle.
24² + x² = 26²
x² = 676-576
x = ±√100
x = 10 (-10 is rejected because length of triangle cannot be a negative number)
Answer:
Step-by-step explanation:
Midpoint = (x₁+ x₂)/2 , (y₁ +y₂)/2
= [(-1)+(-3))/2] , (-2 + 9)/2
= (-4/2) , (-7/2)
= (-2 , -3.5)
Answer:
In Step 1: option D is correct
And in step 2: option A is correct.
Step-by-step explanation:
We have been given the graph
The figure in fourth quadrant after rotating 90 degrees counterclockwise about the origin will shift in first quadrant.
And after translating 4 units left will give the figure shown in second quadrant.
Therefore, In Step 1: option D is correct
And in step 2: option a is correct.
