Answer:

isosceles triangle

Step-by-step explanation:

line CB is the transversal for the two parallel lines, so angle CBA and angle BCE are the same.

since a straight line is 180 degrees, we can solve for angle BCA by subtracting the other angles on the line from 180

180-80-50 = 50

since triangles have 180 degrees, we can solve for the last angle by subtracting the angles we already know from 180

180-80-50

two of the angles are the same, making this an isosceles triangle

1/3k+80=1/2k+120 what does k equal?

LenaWriter [7]

Answer:

k = -1/240

Step-by-step explanation:

to evaluate the value of k in the expression 1/3k+80=1/2k+120

we have

1/3k+80=1/2k+120

collect the like terms for easy evaluation

1/3k - 1/2k = 120 -80

1/3k - 1/2k = 40

find the lcm

2 - 3/6k = 40

-1/ 6k = 40

cross multiply

6k x 40 = -1

240k = -1

divide both sides by 240

240k/240 = -1/ 240

k = -1/240

therefore the value of k in the expression 1/3k+80=1/2k+120 is equals to -1/240

Ms.Wright opens a savings account with a deposit of $800. The bank will pay her 3% interest per year A.) how much interest will

Norma-Jean [14]

A) Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Ms.Wright receive $24 as interest at the end of 1 year.

Step-by-step explanation:

The sum deposited in the bank = Principle = $800

The rate of simple interest = 3%

The time = 6 months = (6/12) years = 0.5 years

$\textrm{SIMPLE INTEREST} = \frac{P \times R \times t}{100} \\\implies SI = \frac{800 \times 3 \times 0.5}{100} = 12$

So, here simple interest = $12.

So Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Now here Time = 1 year

so, Simple interest = $\frac{800 \times 3 \times1 }{100} = 24$

So Ms.Wright receive $24 as interest at the end of 1 year.
