Answer:
∠S = 38°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so you have ...
(x+17)° +(2x-2)° +(5x+5)° = 180°
8x +20 = 180 . . . . . divide by °, collect terms
8x = 160 . . . . subtract 20
x = 20 . . . . . . divide by 8
∠S = (2x -2)° = (2·20 -2)°
∠S = 38°

Travelling with a current, a boat covers a distance 1.5times greater than travelling against the current in the same amount of time. What is the speed of the boat in still water if the speed of the current is 1.5 mph
Answers
and the speed of the boat in still water equal b.
b + c = 1.5 (b - c)
b + c = 1.5b - 1.5c
0.5b = 2.5c
b = 5c
The speed of the current is 1.5 mph so
b = 5 * 1.5 = 7.5 mph

What is the measure of x?
Answers
Answer:
38°
Step-by-step explanation:
y = 142°
x + y = 180°{ being supplementary angles }
x + 142° = 180°
x = 180° - 142°
x = 38°

Answers
Answer:
Step-by-step explanation:
To multiply 4×5⅜, the mixed number can be broken down into a whole number and a fraction. In this case, that whole number would be 5 and the fraction would be three-eighths. Each of these parts are then multiplied by 4 and the products are added together.
4×5⅜ = 4×(5+⅜)
= 4×5 + 4×⅜
= 20 + 3/2
= 20 + 1½
= 21½

What is the length of arc S shown below? Enter an exact expression. The angle in the figure is a central angle in radians.
Answers
Answer:
The arc length S = 11.304 cm
Step-by-step explanation:
Explanation:-
Given that the radius of the circle 'r' = 6 cm
Given that the central angle = [tex]\frac{3\pi }{5}[/tex]
The Arc length is defined by
S = r θ
S = 6 × [tex]\frac{3\pi }{5}[/tex]
[tex]S = \frac{18\pi }{5}[/tex]
[tex]S = \frac{18(3.14) }{5}[/tex] (∵ π = 3.14)
S = 11.304 cm
The arc length S = 11.304 cm

Write an equation in slope-intercept form for the line between (2,7) and (6, 19)
Answers
Answer:
y= 3x +1
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope and c is the y-intercept.
Gradient= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
☆ (x1, y1) is the 1st coordinate and (x2, y2) is the 2nd coordinate
Using the formula above, slope of line
[tex] = \frac{19 - 7}{6 - 2} \\ = \frac{12}{4} \\ = 3[/tex]
Subst. m=3 into the equation:
y= 3x +c
To find the value of c, substitute a pair of coordinates.
When x= 2, y= 7,
7= 3(2) +c
7= 6 +c
c= 7 -6
c= 1
Thus, the equation of the line is y= 3x +1.
