ΔABC is a right triangle in which is a right angle, AB = 1, AC = 2, and BC = .

1 answer:

8 0

We are asked to solve for the measurement of side BC in the given right triangle ΔABC and other side measurements were also given such as AB=1 and AC = 2. Since this is a right triangle, we can use and apply the Pythagorean theorem c²= a² + b² and the solution is shown below:
c = AC
b = BC
a = AB
AC² = AB² + BC² , substitute values we have:
2² = 1² + BC²
BC² = 4-1
BC = √3
BC = 1.732

The answer for the length of BC is 1.732 units.

Let’s think about another type of scenario. What if you were told that a bracelet requires 10 beads and 10 minutes to make while

Georgia [21]

Answer:

$425

Step-by-step explanation:

Let x represent the number of bracelets made and let y represent the number of necklace made.

Since the craftsman has 1000 beads to work with, hence:

10x + 20y ≤ 1000 (1)

Also, the craftsman has 1600 minutes, hence:

10x + 40y ≤ 1600 (2)

From ploting equations 1 and 2 on the geogebra online graphing, we can see that the solution to the problem is (40, 30).

Since the bracelet costs $5 and a necklace costs $7.50, hence the maximum revenue is:

Revenue = 5x + 7.5y = 5(40) + 7.5(30) = $425

Chen has 17CDs. She gives 2 to her brother and buys 4 more. Her brother gives her 1 and she gives 3 to her best friend. How many

d1i1m1o1n [39]

Answer: she has 17 CDs now.

Step-by-step explanation:

The total number of CDs that Chen had initially is 17.

She gives 2 to her brother. This means that she would be having

17 - 2 = 15

She buys 4 more. It means that she would be having

15 + 4 = 19

Her brother gives her 1. So the number that she has is

19 + 1 = 20

she gives 3 to her best friend. Therefore, the number of CDs that Chen has now is

20 - 3 = 17

What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)

LuckyWell [14K]

Answer:

y= -4/5x+33/5

Step-by-step explanation:

for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.

x1=7 and y1=1

x2=-3 and y2=9

now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5

now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.

to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).

1= -4/5 x 7+b. b= 33/5

HOPE THIS HELPS!!
