Answer:
The customer's total cost for the DVD is $19.26
Step-by-step explanation:
Store buy the dvd for $12.00.
The store price is $12.00+50% more
The store price= $12.00 *(1+0.5)= $18.00
Final price (tax added)= $18.00 + 7%
Final price= $18.00 * (1 + 0.07)= $19.26
Answer:
Triangles ABC and DCB are congruent by SAS
Step-by-step explanation:
Angle CAB is congruent to angle CDB. Side DB is congruent to side AC. Then Ab is congruent to side CD.
What is the exact question? It seems like you are asking for the Pythagorean theorem. Ok, I’ll try to help if that’s the case.
a^2 + b^2 = c^2
4^2 + 5^2 = c^2
16 + 25 = c^2
41 =c^2
6.403124237432849 = c
So now since we have the answer, we need to figure out if this result and 6 are equal.
6^2 = 36
25 + 16 = 41
41 and 36 are not equivalent so if the case is that u want me to find the Pythagorean theorem, then the answer is that they aren’t equal. And the real answer is that c equals 6.403124237432849. Which means that 4in, 5in, 6in is not the correct order. And that 16in, 25, 41 is the correct order.
I hope this helped!
Correct answer: <span>y=1/2x-5
</span>
given: point = (2,-4)
slope = 1/2
Explanation: equation of line is: y = mx + c
where, m is the slope
c is the y-intercept
Now,
here, y = 1/2x + c
put, x = 2, y = -4
we get, -4 = (1/2).2 + c
or c = -4 - 1
or c = -5
Hence, equation of line is : y = 1/2x-5
Answer:
Step-by-step explanation:
length=4×28=112 mm=11.2 cm
three centers form an equilateral triangle each side=2×28=56mm=5.6 cm
to find the height
h=√(5.6²-2.8²)=2.8√3
width=2.8+2.8√3+2.8=5.6+2.8√3=2.8(2+√3)
area=11.2×2.8(2+√3)≈117.03 7cm²≈117 cm²
