Answer: 0.4m

Step-by-step explanation:

From the question, photographer takes a picture of a train travelling at the speed of 40m/s and the camera takes 0.01sec to take picture. We want to know the distance that the train travelled in this time.

Distance = speed × time

Distance = 40m/s × 0.01s

= 0.4m

In rhombus MOTH, angle HTM=(5x+6) degrees. If angle HMO=(12x-6)degrees, what is angle HMO?
forsale [732]

Answer:

m∠HMO=102°

Step-by-step explanation:

we know that

In a Rhombus the diagonals bisect the angles and opposite angles are equal

In this problem

Angles HMO and HTO are opposite angles

m∠HMO=m∠HTO

m∠HTM=(1/2)m∠HMO ----> because the diagonals bisect the angles and opposite angles are congruent

substitute the values

(5x+6)\°=(1/2)(12x-6)\°

solve for x

10x+12=12x-6\\12x-10x=12+6\\2x=18\\x=9

<em>Find the measure of angle HMO</em>

m∠HMO=(12x-6)°

substitute the value of x

m∠HMO=(12(9)-6)=102°

see the attached figure to better understand the problem

Triangle DEF is on a coordinate plane with its
antoniya [11.8K]

Answer:

21\ \text{square units}

Step-by-step explanation:

The points are D(-3,5), E(-3,-2) and F(3,0).

Area of a triangle is given by

A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}

\Rightarrow A=\dfrac{-3(-2-0)+-3(0-5)+3(5-(-2))}{2}

\Rightarrow A=21\ \text{square units}

The area of the given triangle is 21\ \text{square units}.
