the mearsure of a triangle are in the ratio 2:3:4 in degrees what is the largest angle in the triangle​

Mathematics

SOVA2 [1]3 years ago
5 0

Answer:

80

Step-by-step explanation:

Since the three angles of a triangle add to give 180°

The the size of the largest angle 4 = 180° ×

                                                      =  180° ×

∴ the size of the largest angle = 80°

tank contains 20002000 liters​ (L) of a solution consisting of 112112 kg of salt dissolved in water. Pure water is pumped into t
Ganezh [65]

Answer:

Answer:

t ≅ 5.09 min

Step-by-step explanation:

we have that if in 4000 L/sol there is 132 kg salt and the pumping speed is 12L/s, we must find how much of salt is pumping per second and then find the amount of salt remaining

12L/s*132kg salt/4000L = 0.396 Kg salt/s,  this means that 0.396 kg per second comes out , It should be found that the amount of salt must be drained so that only 11 kg of salt remain

132kg salt - 11 kg salt = 121 kg salt, so

121Kg salt*s/0.396Kg salt ≅ 305.55 s ⇒ 305.55s*min/60s ≅ 5.09 min

Given ΔABC with A(–4, –2), B(4, 4), and C(18, –8), write the equation for the line containing median segment The term is line se
Monica [59]
Here we want to find the equation of the line containing the median CP.

P, being the midpoint of AB can be found using the midpoint formula as:

\displaystyle{ P=( \frac{-4+4}{2} ,  \frac{-2+4}{2} )=(0, 1).


The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{-8-1}{18-0}= \frac{-9}{18}= \frac{-1}{2}.


Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

y-1= \frac{-1}{2}(x-0)\\\\y= -\frac{1}{2}x+1.


Answer: y=-\frac{1}{2}x+1

What is an equation for the line with slope 2/3 and 7-intercept 9? 30 points to whoever answers this correctly and gets brainlie
Annette [7]

The equation of the line is y = \frac{2}{3} x + 9

Step-by-step explanation:

The equation of a line in slope-intercept form is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept ⇒ the value of y when x = 0

∵ The line has a slope \frac{2}{3}

∴ m = \frac{2}{3}

∵ The y-intercept is 9

∴ b = 9

- Substitute the values of m and b in the form of the equation below

∵ y = m x + b

∴ y = \frac{2}{3} x + 9

The equation of the line is y = \frac{2}{3} x + 9

Solve the system of equations {3x-y=10, -x y=12} for Y
Novosadov [1.4K]
3x - y = 10 . . . (1)
-x + y = 12 . . . (2)

(1) + (2) => 2x = 22 => x = 22/2 = 11

From 2, -11 + y = 12 => y = 12 + 11 = 23
