Answer:
3cm
Step-by-step explanation:
A particular satellite is 15 m wide
Model of it was built with a scale of 1 cm: 5 m
=> scale of the model will be: 1/500cm and A particular satellite is 1500 cm wide
=>1500*1/500=3(cm)
Answer:
105 degrees
Step-by-step explanation:
To start this think about what you know has to be true about this:
- Angle WRQ and PRQ when added will equal 180
- Triangle PRQ when all the angles are added will equal 180
- We have to find x to find what the angle measure of angle WRQ is
So let's start to write an equation:
Let's say angle PRQ is y.
20x + 5 + y = 180
27 + y + 14x + 8 = 180
Now let's use substitution to solve for y:
20x + 5 + y = 180
subtract 5 from both sides:
20x + y = 175
subtract 20x from both sides:
y = -20x + 175
Let's now plug in y to our other equation:
27 + (-20x + 175) + 14x + 8 = 180
now combine all like terms:
-6x + 210 = 180
now solve for x:
subtract 210 from both sides:
-6x = -30
divide both sides by -6:
x = 5
Now that we have x, let's plug it in for the equation of angle WRQ:
20(5) +5
Simplify:
105
Hope this helps!
Answer:
c. (3, 2)
Step-by-step explanation:
Equating the values of y :
- -x + 5 = x - 1
- x + x = 5 + 1
- 2x = 6
- <u>x = 3</u> [x-coordinate of the solution]
Finding y by substituting x in one of the equations :
- y = x - 1
- y = 3 - 1
- <u>y = 2</u> [y-coordinate of the solution]
Solving :
- Solution = (x, y)
- Solution = (3, 2)
