Mathematics
1 answer:
Pavel [41]3 years ago
5 0

Answer:

a) 92 m

b) 74 cm

Step-by-step explanation:

a)

2(length) + 2(width) = perimeter

2(x) + 2(73) = 330 m

2x + 146 = 330

2x = 184

x = 92 m

b)

length * width = area

85 * x = 6290 cm²

85x = 6290

x = 74 cm

Find the value of the variable in the parallelogram.<br><br> RZ = 4x + 2<br> SW=9x - 8<br><br> X=
ipn [44]

Answer:

x=12

Step-by-step explanation:

This parallelogram contains a right angle. This tells us that the parallelogram is a rectangle.

The diagonals in a parralelogram bisect each other.

The diagonals in a rectangle are congruent.

RZ+ZT=RT\\(4x+2)+(4x+2)=RT\\8x+4=RT

RT=SW\\8x+4=9x-8\\4=x-8\\x=12

Phil and matt make cookies for a fundraiser at their school
Ivahew [28]
The equation would be y=0.45x.

Let x be the number of cookies Matt made.  Since Phil made 25% more, and 100%+25%=125%=125/100=1.25, the number of cookies Phil made can be represented by 1.25x.

Together the cookies they made are represented by x+1.25x=2.25x

Since there were 20% of the cookies remaining, this means they sold 100%-20%=80%=80/100=0.8 of the cookies:
0.8(2.25x) = 1.8x

Each cookie sold for 0.25, so we have
0.25(1.8x) = 0.45x

Letting y be the money they make, we have
0.45x=y
