Use of distributive property will be
(30 x 5) + (9 x 5)
21. the error for x - 28 = 375 is not 347 is because the student subtracted both sides by 28. 347 - 28 is 319 not 375. One must add 28 to both sides of -28 and 375. The -28 and 28 is zero. 375 + 28 = 403.
22. The next three terms are 0.93, 1.02, and 1.11. The rule in the number pattern is one must add 0.09.
Answer: 94 cm^3.
Step-by-step explanation: You use the formula 2(ab+bc+ca). You plug in 3, 4, and 5 to get 94.
The distance between park station 1 and the point where the flare was set off is 73.9 km.
<h3>What is distance?</h3>
Distance is the length between two points expressed in meters or kilometers.
To calculate the distance between park station 1 and the point where the flare was set off can be calculated using Sine Rule
Formula:
- a/sinA = b/sinB....................... Equation 1
Where:
- a = Distance between park station 1 and the point where the flare was set off.
Make a the subject of the equation
- a = bsinA/sinB............ Equation 2
From the diagram,
Given:
- A = 59°
- B = (180-59-75) = 46°
- b = 6.2 km
Substitute these values into equation 2
Hence, the distance between park station 1 and the point where the flare was set off is 73.9 km.
