CRITICAL THINKING The total area of the polygon is 176 square feet. What is the value of $x$ ?
Katarina [22]

Answer:

x = 6

Step-by-step explanation:

this figure involves two triangle and one rectangle

for area of rectangle= Length * Width = 16 * 8 = 128 feet^2

for area of one triangle = 1/2 * base * height = 1/2 * x *8 = 4x

for two triangles = 8x ft^2 total

whole area = two triangles + one rectangle

176 = 8x + 128

8x =48

x = 6

A company buys pens at the rate of $5.50 per box for the first 10 boxes, $4.50 per box for the next 10 boxes, and $3.50 per box
marusya05 [52]

So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 55$ obviously. Secondly 45$ for the next 10 boxes.

So for now we can simply calculate that we have spent around 100$ which means 20 boxes. The remaining money left is 77$ so we can buy 77/3.5 = 22 only 22 boxes with that money. Hence a total of 42 boxes.

Agora chess club has 16 members and gains a new memeber every month. The key club has 4 members and gains 4 new members every mo
svlad2 [7]

Answer:

For chess club:

y1 = 16 + 1*x where y1=total number of members after x months  

For film club

y2 = 4 + 4*x where y2=total number of members after x months  

y1 = y2 at  

16 + x = 4 + 4x

3x = 12  

x = 4  

Therefore, after 4 months they the same number of members (equals 20 members, 16 + 1*4 or 4 + 4*4).

Type the dimensions of a different shaped box that has the same volume
defon

Step-by-step explanation:

120ft³ = 3ft × 4ft × 10ft

120ft³ = 1ft × 1ft × 120ft

120ft³ = 2ft × 2ft × 30ft

120ft³ = 5ft × 3ft × 8ft

...

Taking fractions or mixed numbers as dimensions, you can give infinitely many such shapes with a volume of 120ft³.
