Answer:

$28.571429\%$

Step-by-step explanation:

1) To convert the fraction to a decimal, divide the numerator by the denominator.

$2 \div 7$

2) Use long division.

$0.285714$

3) To convert to a percent, multiply the decimal by 100.

$0.285714 \times 100 = 28 .571429$

4) Add the percent sing.

In Triangle BCD, BC=BD, and angle B =13x-35, angle C = 5x-19, angle D=2x+14. Find the measure of each angle

aleksandr82 [10.1K]

Answer:

$B = 108$

$C = 36$

$D = 36$

Step-by-step explanation:

Given

$B =13x - 35$

$C = 5x - 19$

$D=2x+14$

$BC = BD$

Required

Determine the measure of each angle

The angles in a triangle sum up t 180. i.e.

$B + C + D = 180$

Since $BC = BD$ , then $C = D$

$B + C + D = 180$ can then be rewritten as:

$B + C + C = 180$

$B + 2C = 180$

Substitute values for B and C

$13x - 35 + 2(5x - 19) = 180$

Open Bracket

$13x - 35 + 10x - 38 = 180$

Collect Like Terms

$13x + 10x = 180 + 38 + 35$

$23x= 253$

Divide both sides by 23

$x = 11$

To get the measure of each angle, substitute 11 for x in the expressions of B, C and D

$B =13x - 35$

$B = 13 * 11 - 35$

$B = 108$

$C = 5x - 19$

$C = 5 * 11 - 19$

$C = 36$

$D=2x+14$

$D = 2 * 11 + 14$

$D = 36$

If your slope is undefined, what would you put for M in Point slope form?

ivann1987 [24]

Answer:

You can not write an equation then because it would just be a vertical line, ex: x=4 or x=-4. I hope this helps!

3(x-6)^4+11=15 solve for x

Tamiku [17]

Answer:

x = 7.07 or 4.925

Step-by-step explanation:

3(x-6)^4+11=15

3(x-6)^4=15-11

(x-6)^4=4/3

x-6 = + $\sqrt[4]{4/3}$ or - $\sqrt[4]{4/3}$

x= + $\sqrt[4]{4/3}$ +6 or - $\sqrt[4]{4/3}$ +6

x = 7.07 or 4.925

Olivia bought some granola bars and spent at least $6.24. Write and solve an equality to find the number of granola bars she bou

marishachu [46]

Answer:

n ≥ 6.24/x

Step-by-step explanation:

Given that :

Amount spent is atleast $6.24

Let price spent = p

p ≥ $6.24

If cost of granola bar = x

The number of granola bars, n purchased will be :

n ≥ 6.24/x

Since cost of granola bar isn't given, we represent it as x.
