<h2>Answer:</h2><h2> Since the rate of change with each value is 12, 12x will appear somewhere in the formula for this sequence. = 12x + c, where c is a constant value. The tenth term gives a value of 52. So, 52 = 12(10) + c c = -68 </h2>

Step-by-step explanation:

$\angle 4, \:60\degree \:\&\:61\degree$ are straight line angles.

$\therefore \angle \: 4 + 60 \degree + 60 \degree = 180\degree \\ \\ \therefore \: \angle \: 4 = 180\degree - 121\degree \\ \\ \huge \red {\boxed {\therefore \: \angle \: 4 = 59\degree}}$

Answer:

$350 * D \geq 1400$

$D\ge 4$

This means that the family must travel for at least 4 days.

Step-by-step explanation:

Given

$Rate = 350\ miles\ daily$

$Distance = 1400\ miles\ (atleast)$

Required

Determine and solve the inequality

The number of days is represented with D

So:

On any D number of days, the family would have covered a distance of 350 * D miles

If the total distance is at least 1400, then the inequality is:

$350 * D \geq 1400$

[The term "At least" is used to represent greater than or equal to]

$350 * D \geq 1400$

Divide through by 350

$\frac{350 * D}{350} \ge \frac{1400}{350}$

$D \ge \frac{1400}{350}$

$D\ge 4$

This means that the family must travel for at least 4 days.

-3 1/2 + ( -6 1/2) = 5/8 - {-2/8} = - 9/10 - 2/5 = 6 3/5 - (-2 1/5)

marin [14]

Answer:

-3 1/2 + ( -6 1/2) = -10

5/8 - {-2/8} = 7/8

- 9/10 - 2/5 = -4

6 3/5 - (-2 1/5) = 44/5

Step-by-step explanation:

-3 1/2 + ( -6 1/2) = -7/2 + (-13/2) = -20/2 = -10

5/8 - {-2/8} = 5/8 + 2/8 = 7/8

- 9/10 - 2/5 = -18-2/5 = -20/5 = -4

6 3/5 - (-2 1/5) = 33/5 + 11/5 = 44/5

The two white triangles have areas of 1/2 x 3 x 10 and 1/2 x 6 x 10 = 15 + 30 = 45 cm^2
The shaded area will be 10 x 10 - 45 = 55 cm^2
The percentage shaded = 55 / 100 x 100% = 55%
