Answer: A

Step-by-step explanation:

Looking at the conditions, we can eliminate D. An isosceles triangle has 2 equal sides. 2 cm, 3 cm, 4 cm don't have 2 equal lengths.

We can next eliminate C. C is a right scalene triangle. Even if this is a scalene triangle, the key is the work "right". Any right triangle, regardless of it's angles, always fit the Pythagorean Theorem. C does not fit the Pythagorean Theorem.

2²+3²=4²

4+9=16

13≠16

We are left with the options A and B. A and B can both be correct answers, but it is the condition given in the problem that makes A the right answer. A states acute scalene triangle. That means there is at least 1 acute angle. Technically, B is also correct, but because the problem explicitly states 29°, that makes A the correct answer.

Answer:

Step-by-step explanation:

The discriminant is what's under the square root sign in the quadratic equation. The equation for the discriminant is $b^{2}-4ac$ , where b is the coefficient of x, a is the coefficient of $x^{2}$ , and c is the number with no variable attatched to it. If we plug in the numbers ( $17^{2} -4*4*3$ ) it gives you 241, which is the discriminant. Since 241 is more than zero, it has 2 zeros. If the discriminant was 0, there'd be 1 zero, and less then zero there would be zero zeros.

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 71°, a

mr_godi [17]

$\boxed{\text{Area of the triangle:} \dfrac{a \times c \times sin(\measuredangle B)}{2}} \\ \\ A = \dfrac{a \times c \times sin(\measuredangle B)}{2} \\ \\ A= \dfrac{11 \times 18 \times sin71 ^o }{2} \\ \\ \\ Note : sin 71^o \approx 0,94 \\ \\ \\ A = \dfrac{198 \times 0,94}{2} \\ \\ A= \dfrac{186.12}{2} \\ \\ A=93.6 \ cm^2$

How many minutes is it before 12 noon if 68 minutes ago it was three times as many minutes past 10 a.m.?

umka21 [38]

If 68 minutes ago it (then) was three times as many minutes past 10 am (now)

x + 68 = 3 ×
×
(120 - x) →
→
x = 73 min
… if 68 minutes ago it (now) was three times as many minutes past 10 am (then)

x = 3 ×
×
[120 - (x + 68)] →
→
x = 39 min
… if 68 minutes ago it (then) was three times as many minutes past 10 am (then)

x + 68 = 3 ×
×
[120 - (x + 68)] →
→
x = 22 min

How the Industrial Revolution changed American Economics.

Feliz [49]

Answer:

The Industrial Revolution shifted from an agrarian economy to a manufacturing economy where products were no longer made solely by hand but by machines. This led to increased production and efficiency, lower prices, more goods, improved wages, and migration from rural areas to urban areas.
