Solve For The Value Of K. How? How Can I Solve It

Answers

Answer 1

Answer:

6

Step-by-step explanation:

The total of all the angles must be 180, since there is a straight line. We already know the 40 degree angle and the 90 degree angle, meaning that the remaining angle must be equal to 180 - 90 - 40, which is 50 degrees. Therefore, 50 = 7k + 8. 7k = 50-8 = 42, and k = 6.

Answers

Answer:

58° , 122° , 29°

Step-by-step explanation:

The triangle on the left has 2 congruent sides thus is isosceles.

Then the 2 base angles are congruent, so

∠ 1 = [tex]\frac{180-64}{2}[/tex] = [tex]\frac{116}{2}[/tex] = 58°

∠ 2 and 58° are adjacent angles and supplementary, that is

∠ 2 + 58° = 180° ( subtract 58° from both sides )

∠ 2 = 122°

The triangle on the right has 2 congruent sides and is isosceles

Then the 2 base angles are congruent, so

∠ 3 = [tex]\frac{180-122}{2}[/tex] = [tex]\frac{58}{2}[/tex] = 29°

0.40

Step-by-step explanation:

Here is a list of the data in order from least to greatest:

$0.00, $0.00, $0.02, $0.40, $1.25, $2.00, $10.75.

There are seven numbers in the list, so the median is the fourth number, which is $0.40.

What are the corordinates of point F on a coordinates plane point F is 4 units to the right and 2.5 units

Answers

Correct Question

What are the coordinates of point F on a coordinates plane point F is 4 units to the right and 2.5 units down.

Answer:

coordinates of point F are (4,2.5)

Step-by-step explanation:

The horizontal line is x axis which is 4 points on coordinate plane.

The vertical line is y axis which is 2.5 points on coordinate plane

the coordinates are written as (x,y)

therefore the coordinates of point F are (4,2.5) as (x,y)

Help me please

Answers

Answer:

4+7/16

Answer is 11/16

Step-by-step explanation:

Transform the expression then calculate

Answer:

11/16

Step-by-step explanation:

First- make sure they have the same denominator (the number located at the bottom)

(the denominator is the least common multiple (LCM) or essentially where the numbers meet up)

^ 4 and 16 meets up at 16.

^7/16 already has 16 as the denominator, however 1/4 does not.

Therefore-

1/4 * 4/4 + 7/16 * 1/1

^ 4/16 + 7/16

(they have the same denominator, therefore when you add you DO NOT change the denominator)

4+7 is 11- and you keep the denominator

11/16 is a number which you can NOT simplify.

Therefore ^ 11/16 is your answer

Answer:

Step-by-step explanation:

"Inversely proportional to x" in this situation is represented by a = k/x.

Find k:

Let a = 15 and x = 25, then calculate k:

15 = k/25)

Multiplying both sides by 25 yields k = 15(25), or k = 3/5

4. Some banks charge a fee on savings accounts that are left inactive for

an extended period of time. The equation y = 5000(0.98)x represents the

value, y, of one account that was left inactive for a period of x years. What

is the y-intercept of this equation and what does it represent? *

Answers

Answer:

(0, 5000)

The value of the account at the start of the year is 5000

Step-by-step explanation:

Given the equation that represents the  value, y, of one account that was left inactive for a period of x years as;

y = 5000(0.98)^x

The y-intercept of the equation occurs at x = 0

Substitute x = 0 into the expression

y = 5000(0.98)^0

y = 5000(1) (any value raise to power of zero is 1)

y = 5000

Hence the y intercept is (0, 5000)

This means that the value of the account at the start of the year is 5000
