<h3>Answer: b = 17</h3>

====================================================

Explanation:

The line must go through the point (5,2) which means x = 5 and y = 2 pair up together.

We'll plug these x and y values into the equation and solve for b.

y = -3x+b

2 = -3(5)+b

2 = -15+b

2+15 = b

17 = b

b = 17

The equation y = -3x+b turns into y = -3x+17

Jack collected 1350 pounds of waste paper for recycling today. If he decided to collect 24% more pounds of waste paper tomorrow,

miv72 [106K]

324 pounds

24% = $\frac{24}{100}$ = 0.24

0.24 × 1350 = 324 pounds

He should collect 324 more pounds of waste paper

A running circuit is in the shape of a triangle with lengths of 6km, 6.5km and 7km. What are the sizes of the angles (in minutes

Rudik [331]

A triangle is an example of a class of figures referred to as plane shapes. It has three straight sides and three internal angles which sum up to $180^{o}$ . The measures of the internal angles of the triangle given in the question are A = $52.6^{o}$ , B = $59.4^{o}$ , and C = $68^{o}$ .

A triangle is an example of a class of figures referred to as plane shapes. It has three straight sides and three internal angles which sum up to $180^{o}$ .

Considering the given question, let the sides of the triangle be: a = 6 km, b = 6.5 km, and c = 7 km.

Apply the Cosine rule to have:

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2ab Cos C

So that;

$7^{2}$ = $6^{2}$ + $(6.5)^{2}$ - 2(6 * 6.5) Cos C

49 = 36 + 42.25 - 78Cos C

78 Cos C = 78.25 - 49

= 29.25

Cos C = $\frac{29.25}{78}$

= 0.375

C = $Cos^{-1}$ 0.375

= 67.9757

C = $68^{o}$

Apply the Sine rule to determine the value of B,

$\frac{b}{Sin B}$ = $\frac{c}{Sin C}$

$\frac{6.5}{Sin B}$ = $\frac{7}{Sin 68}$

SIn B = $\frac{6.5 *Sin 68}{7}$

= 0.861

B = $Sin^{-1}$ 0.861

= 59.43

B = $59.4^{o}$

Thus to determine the value of A, we have;

A + B + C = $180^{o}$

A + $59.4^{o}$ + $68^{o}$ = $180^{o}$

A = $180^{o}$ - 127.4

= 52.6

A = $52.6^{o}$

Therefore the sizes of the internal angles of the triangle are: A = $52.6^{o}$ , B = $59.4^{o}$ , and C = $68^{o}$ .

Please help I don’t understand.... I will give brainliest to first and I will thank you!

Stolb23 [73]

To find the answer we can break the figure into two parts: a rectangle and a semi circle.

The perimeter of the rectangle:

(10+4)×2

=28 ft

The perimeter of the semi circle:

perimeter of a circle: 2×兀×radius

(The radius: 4/2)

We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.

[2(3.14)(4/2)] / 2

=6.28 ft

We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:

28+6.28-4

=30.28ft

Therefore the answer is 30.28ft.

Hope it helps!

Help Me Please!!! : Determine the intercepts of the line.

DENIUS [597]

Answer:

The intercepts if this line are -7 and 2.

Y-intercept is (0,2)

and the other one is (-7,0)

Intercpts are where the line goes through another line.
