Answer:
42.0 ft
Step-by-step explanation:
let t be the height of the tree.
<u><em>At the same time ,the measure of something </em></u>
<u><em>and its shadow are proportional</em></u> .
Then
Then
2t = 6 × 14
Then
2t = 84
Then
t = 84/2
Then
t = 42
Therefore the tree is 42 ft tall
Brian is correct. Because when you add or subtract fractions with common denominators, it follows the rule of addition. The denominator stays the same and you simply need to get the sum of the numerators. It is pretty straightforward. For example:
Answer:

Answer:
y = 8x + 9
Step-by-step explanation:
Parallel lines have the same gradient,
So m = 8
y = 8x + c
When x = -1 ,y = 1
1 = 8(-1) + c
c = 9
y = 8x + 9
Answer:
मापनको एकाईलाई हर्ट्ज (हर्ट्ज) भनिन्छ, जुन प्रति सेकंड टेक्निकली एक चक्र हो, घडीको गति मापन गर्न प्रयोग हुन्छ। ... कम्प्युटरको घडी गति सामान्यतया मेगाहेर्ट्झ (मेगाहर्ट्ज) वा गिगाहर्ट्ज (GHz) मा मापन गरिएको छ। एक मेगाहेर्ट्ज प्रति सेकेन्ड १० लाख टिक्स बराबर हुन्छ, र एक गिगाहर्ट्ज बराबर एक सेकेन्ड टिक टिक प्रति सेकेन्ड।
