Problem #3

Mathematics
1 answer:
AfilCa [17]2 years ago
8 0

Answer:

b = 115.4 feet

Step-by-step explanation:

b^2 = a^2 + c^2 - 2 (a)(b) x cos B

b^2 = 230^2 + 360^2 - 2(230)(360) x cos(38 degrees)

b^2 = 52,900 + 129,600 - 2(230)(360) x cos(38 degrees)

b^2 = 182,500 - 165,600 x cos(38 degrees)

b = \sqrt{(16,900)(cos(38)) }

b = 115.4 feet

i hope this helps!! :)

Write an equation of the line that is perpendicular to y = 1/2
atroni [7]

Answer:

the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)

= -5 = -2x + 15

Step-by-step explanation:

Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).

Using the slope intercept equation,

y = mx +c

m = slope = 1/2

For two lines to be perpendicular, the product of their slopes is -1

Let the slope of the other line be m2

m1×m2 =-1

1/2×m2 = -1

m2 = -1/(1/2) = -2

Slope of line = -2

For points (10, -5), x = 10, y =-5

-5 = -2× 10 +c

-5 = -20+ c

c = -5+20= 15

the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)

-5 = -2x + 15

10 beads fit on a bracelet. Ben has 34 beads in all. How many bracelets can he make with 10 beads on each
Lady_Fox [76]

Answer:

3 with a remainder of 4 beads

Step-by-step explanation:

if you want to put 10 beads on each bracelet but you only have 34 beads you are going to do subtraction (this is division but subtraction is the easiest way to explain it) so you have 34 bead and that’s more than 10 so you can make a bracelet so subtract 10 from 34, so now you have 24 beads and one bracelet, now 24 is greater than 10 so subtract again, 24-10 which is 14 so now you have 14 beads and 2 bracelets and 14 is greater than 10 so we can make another, 14-10 is 4 so now you have 4 beads and 3 bracelets now 4 is less than 10 so you can’t make another (hope this helps)

If a student has an average exam score between 70 and​ 79, he will earn a grade of C in his algebra course. Suppose he has three
goldenfox [79]

Answer:

(64,86.5)

Step-by-step explanation:

find the case where he gets 70 and the case where he gets 79

if his average is 70:

(75+62+85+2x)/5=70

(222+2x)/5=70

222+2x=350

2x=128

x=64

if his average is 79:

(75+62+85+2x)/5=79

(222+2x)/5=79

222+2x=395

222+2x=395

2x=173

x=86.5
