Answer:
100 inches
Step-by-step explanation:
A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.
This is calculated using proportion
Side length/Perimeter
Hence:
Side length of smaller triangle = 19 inches
Perimeter of smaller triangle = 95 inchee
Side length of larger triangle = 20 inches
Perimeter of larger triangle = x
19/95 = 20/x
Cross Multiply
19x = 95 × 20
x = 95 × 20/19
x = 100 inches
The perimeter of the larger triangle = 100 inches
Answer:
A) 0.05
Step-by-step explanation:
Let's summarize into an equation the information we can get from that table.
We have 4 liters of an acid of an unknown concentration, let's call it (4x).
We have 10 liters of an acid with known concentration of 0.40.
And we have a total of 14 liters overall with a concentration of 0.3o.
That's like a weighted average formula: 4x + 10 y = 14z
Let's replace the concentration values we know and solve this:
4x + 10 (0.4) = 14 * 0.3
4x + 4 = 4.2
4x = 0.2
x = 0.05
So, the concentration of the 4 liters of acid on concentration X are in fact of concentration of 0.05.
To find the y-intercept, we set x=0 and solve for y.
Answer:
45°
Step-by-step explanation:
Complementary angles sum to 90°, thus
90° - 45° = 45° ← is the complement of 45°
Answer:
Compount interest earns more. Difference between 2 interest is $92 445.39
Step-by-step explanation:
Simple Interest:
p = $10000
r = 3%
t = 2years
I = (10000×3×2)/100
= $600
Total amount = $10 600
Compound Interest:
p = $100000
r = 3/730 (daily)
t = 730 (2yrs)
A = 100000[1+(3/73000)]^730
= $103 045.39 (2d.p)
Difference = $103045.39 -
$10600
= $92 445.39
