Answer:
<em>B. 25,636 feet</em>
Step-by-step explanation:
sin(55) = h/x
h = 21,000
sin(55) = 21,000/x
x = 21,000/sin(55)
x = 25636.27 ≈ 25,636 feet
Hope this helped! :)
Answer:
The second number is four more than, two times the first number. The third ... Start by writing an expression for each of the three numbers. They are all formed from the first number, so let's call the first number x . Let the first number be x. The second number is 2x+4. The third number is 3x−5. We are told .
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
divide both sides by 5- 2x + 5 = 13 subtract 5 from both sides
- 2x = 8 divide both sides by 2
- x = 4
Answer:
Part A
30
44
26
Part B
176
Step-by-step explanation:
Total: 65+110+75 = 250
P(O) = 75/250 × 100 = 30%
P(A) = 110/250 × 100 = 44%
P(K) = 65/250 × 100 = 26%
Apple juice:
44% of 400
44/100 × 400

Answer:
2m/s²
Step-by-step explanation:
If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:
F∝a
F = ka.
F is the force
a is the object's acceleration
From the expression;
k is the constant of proportionality
When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then
k = 25/5
k = 5Ns²/m
If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above
F = ka
Given F = 10N and k = 5Ns²/m
a = F/k = 10/5
a = 2m/s²
The acceleration of the object will be 2m/s²
