Answer:
C. 1059.50
Step-by-step explanation:
Sales price x sales tax rate = sales tax
16299.99 x .065 (6.5%) = 1059.50
Step-by-step explanation:
<u>Given:</u>
- Investment P₁ = $3670
- Investment P₂ = $2040
- Rate of interest r₁ = 1.9% SI
- Rate of interest r₂ = 5.5% SI
- Time t = 5 years
<u>Find amount of interest in both investments:</u>
- I₁ = P₁r₁t = $3670*(1.9/100)*5 = $348.65
- I₂ = P₂r₂t = $2040*(5.5/100)*5 = $561.00
<u>As we see the</u><u> online savings account</u><u> earns more interest and the difference is:</u>
- $561.00 - $348.65 = $212.35 ≈ $212
Because the two triangles together create another 90 degree angle on the right-most side, we can tell the triangle is a 45-45-90 triangle
So the base of the height (the given value is 3). Because it is a 45-45-90, the height is also 3.
You can now find x by using Pythagorean theorem OR just the proof of a 45-45-90 triangle.
Pythagorean theorem version:
a^2 + b^2 = c^2
3^2 + 3^2 = x^2
9 + 9 = x^2
18 = x^2
x = 3
45-45-90 proof
The legs of a 45-45-90 triangle are congruent so you just take the value of a leg and place a
at the end of it.
Leg length is 3 units. Slap a
on the end; answer is 3
Answer:
98
Step-by-step explanation:
the time taken is directly proportional and so we multiply 7 by 56 and the divide the answer by 4 to get 98
