Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h

23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified


24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values

.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.

Help with translations!
Vadim26 [7]

Given:

The figure of a trapezoid.

The figure is translated down 5 units and then rotated 180 degrees clockwise.

To find:

The coordinates of the image of point W after these transformation.

Solution:

From the given figure it is clear that the coordinates of point W are (-6,3).

The figure is translated down 5 units. So,

(x,y)\to (x,y-5)

W(-6,3)\to W'(-6,3-5)

W(-6,3)\to W'(-6,-2)

After that the figure is rotated 180 degrees clockwise.

(x,y)\to (-x,-y)

W'(-6,-2)\to W''(6,2)

Therefore, the coordinates of point W after the given transformations are (6,2).

In the accompanying diagram, what is sin E? A. B. E C. D. 4 G A B С OD​
IRINA_888 [86]

Answer:

Sin(E) = \frac{4}{5}

Step-by-step explanation:

The full question is as follows :

To find - In the accompanying diagram, what is sin E?

Proof -

We know that,

Sin(theta) = (opposite side) / (hypotenuse)

From the diagram, we can see that,

Base = 3

Perpendicular = 5

Hypotenuse = 5

So,

For angle E,

Opposite side = 4

Hypotenuse = 4

∴ we get

Sin(E) = \frac{4}{5}

100 Points <br> Easy question <br><br><br> Topic: Multiplying and dividing fractions
katrin [286]

Answer:

see below

Step-by-step explanation:

The trip takes 2 hours

Stopping every half hour means stopping at 30 minutes, 1 hour, 1.5 hours

We would not stop at 2 hours because we would be done.

One the number line R means rest stops

200 Km /4 means at 50 km, 100 km 150 km and 200 km

The rest stops are at 50 km 100 km 150 km  (the one at 200 is at the end of the trip so it is not a rest stop

We have to stop for gas 3/4 of the way

200 *3/4 = 150 km

We will stop for gas at a rest stop at 150 km

Find the domain and range of this relation? (Assume there are arrows at both ends of the relation.)
Radda [10]

Answer:

Domain: ( -∞ , ∞ )
Range: ( -∞ , 4 ]

Step-by-step explanation:

Hi there!

The domain tells us the possible x-values of a function. Because there are arrows at the end of each side, it means the graph is travelling infinitely to both the left and the right side. This means the the domain is all real numbers, meaning that for any value of x, there is a real value for y.

( -∞ , ∞ )

The range tells us the possible y-values of a function. Both sides of the graph are travelling infinitely downwards, starting from 4.

( -∞ , 4 ]

I hope this helps!
