Triangle ABC has perimeter 22 cm.
AB = 8cm
BC = 5cm
By calculation, deduce whether triangle ABC is a right-angled triangle.

Answers

Answer 1

Answer:

Step-by-step explanation:

A = 8 cm

B = 5 cm

C = 22 - 8 - 5 = 9 cm

Use the Pythagreom Theroem (a^2 + b^2 = c^2) if the two sides are equal to one another than it is a right triangle.

8^2 + 5^2 = 9^2

64 + 25 = 81

89 = 81

89 does not equal 81, so this is not a right triangle.

Answer:

x = 18

Step-by-step explanation:

10  − 3x = − 2 (x + 4)

=> 10  − 3x = -2x - 8

=> x = 18

Hoped this helped.

Answer:

x = 18

Step-by-step explanation:

10 - 3x= -2(x+4)

First, we solve inside the parentheses.

10 - 3x= -2x - 8

Like terms:

-3x + 2x= -10 - 8

-x/-1 = -18/-1

x = 18

4800 persons run a marathon, 1200 reach the finish line. What is the percent of people reach the finish line at the marathon?

Answers

Answer: 25%

Step-by-step explanation: So first make the number of people who ran the marathon and the number of people who finished the marathon into a ratio

1200:4800

then make that into a fraction, 1200/4800

then make the percent of people who reached the marathon into a fraction, using 100 as the denominator and a variable as the numerator.

for example. p/100 (p, represents the percent)

then cross multiply.

1200x100=1200000

Last divide 1200000 by 4800 to get 25%.

Answer:

y = 12

x = 4.4

Step-by-step explanation:

Scale factor is calculated by comparing the opposing side lengths and writing them as a fraction:

8/20 = 2/5 is the scale factor now to find the value of x and y we can use this scale

y/30 = 2/5 cross multiply expressions

5y = 60 divide both sides by 5

y = 12

same goes for x:

x/11 = 2/5 cross multiply

5x = 22 divide both sides by 5

x = 4.4

Using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 0-3)/(2-0)

The y intercept is 3

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept
