When Famke charges her phone, it gains 2 percentage points each minute. When Frmke uses her phone, it loses 5 percentage points

pentagon [3]

It only lasts for 20 minutes, and takes 50 minutes to charge (She needs a new phone). 100-(10*5)=50
50+(20*2)=90%
she uses it for 10 minutes and charges it for 20 minutes.

What is the length of BC¯¯¯¯¯ ? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vertex A lies above

OlgaM077 [116]

Answer: The length of BC is 22 units.

Explanation:

It is given that the Triangle ABC with horizontal side BC. Vertex A lies above side BC. Angle B and angle C are marked congruent. The length of side AC is labeled as 2x-24. The length of side AB is labeled as x-2. The length of side B C is labeled as x.

If two angles of a triangle are same it means the triangle is an isosceles triangle.

Since the angle B and C are congruent therefore the lines AB and AC are same.

$2x-24=x-2$

$2x-x=-2+24$

$x=22$

Since the side BC=x therefore the measure of BC is 22 units.

identify an equation in point slope form for the line perpendicular to the y=-1/2x+11 that passes through (4,-8). a. y+8=1/2(x-4

Solnce55 [7]

Answer:

d. y+8=2(x-4)

Step-by-step explanation:

There are 2 important parts to this question. First, understanding which slopes are perpendicular. The negative reciprocal of a number will be perpendicular to it. So, since the original slope is -1/2 the new slope should be 2.

Then, remember what the point-slope formula is. The point-slope formula is: $y-y_{2}=m(x-x_{2})$ . So if you plug in the point and slope the new equation looks like, $y--8=2(x-4)$ . Then, simplify for the final answer of $y+8=2(x-4)$ .
