A scale model of a street sign is in the shape of a triangle. The base is 4.25 cm and the height is 8.8 cm what is the area of t

agasfer [191]

Answer:

18.7 cm²

Step-by-step explanation:

To work out the area of a triangle you have to use the formula

$\frac{1}{2} * B * H$

Where "B" is the base and "H" is the height

Since these are decimals, I like to convert them into fractions which makes them easier to calculate with

The base is 4.25 cm which will turn into $4\frac{1}{4}$

The height is 8.8 cm which will turn into $8\frac{8}{10}$

Now we use the formula

$\frac{1}{2} * B * H$

$\frac{1}{2} * 4\frac{1}{4} *8\frac{8}{10}$

→ Convert to improper fractions

$\frac{1}{2} * \frac{17}{4} *\frac{88}{10}$

→ Simplify

$\frac{187}{10}$

→ Convert into decimal

18.7

Rzqust [24]

In order to find the number of hats, multiply all the choices together, disregarding size:

4 * 4 * 7 <-- 4 styles * 4 stitches * 7 yarns
= 16 * 7 = 112

112 different hats can be made.

Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral a b c d the coordinates of a r the reflected q

Zina [86]

Solution :

From the figure,

The coordinates of --

A = (-5,-3)

B = (-6,-1)

C = (-3,-1)

D = (-2,-3)

When it undergoes reflection about x-axis, we have the coordinates of the quadrilateral as

A' = (-5,+3)

B' = (-6,+1)

C' = (-3,+1)

D' = (-2,+3)

Now A'B'C'D' is translated 3 units to right, so the coordinates will be --

A" = (-2,3)

B" = (-3,1)

C" = (0,1)

D" = (1,3)

When the quadrilateral moves third and two units up, we get

A"' = (3,3)

B"' = (2,1)

C"' = (5,1)

D"' = (6,3)
