Answer: x = 21; y = 29.5

because 2y° and 59° are 2 opposing angles ⇒ 2y° = 59° ⇔ y = 29.5°

we also have: (3x - 4)° = 59° ( because of 2 parallel lines)

⇔ 3x = 59 + 4 = 63

⇔ x = 63/3 = 21

.25(4) = 1 gallon

.25(8) = 2 gallons

.25(12) = 3 gallons

.25(16) = 4 gallons

.25(20) = 5 gallons

it would take 20 minutes to remove half the water (aka 5 gallons)

Can someone help me please

malfutka [58]

Answer:

-2.5

Step-by-step explanation:

We need to find the slope using and two points

m = ( y2 -y2)/(x2-x1)

= ( 25-20)/(-10 - -8)

= 5/( -10+8)

= 5/-2

- 2.5

The side of a square is 2.5 cm. Find its perimeter and area.

Neko [114]

Answer:

Perimeter = 10 cm

Area = 6.25 cm²

Step-by-step explanation:

$\bf \: Given :$

$\sf \: Side \: of \: the \: square = 2.5 \: cm$

$\bf \: To \: find:$

$\rightarrow \sf \: Perimeter$

$\sf\rightarrow Area$

$\bf \: Solution :$

$\rm \: First \: w e \: need \: to \: find \: out \: the \: perimeter \: o f \: it.$

So to find the Perimeter of the square, we'll use this formula :

$\boxed{ \sf\longrightarrow \: Perimeter = 4 \times side}$

$\bf \: Step \: 1 : \rm \: Put \: the \: value \: of \: side \: of \: the \: square :$

$\sf\longrightarrow \: Perimeter = (4 \times 2.5)cm$

$\bf \: Step\;2 : \rm Multiply :$

$\sf\longrightarrow \: Perimeter = 10 \: cm$

Hence, the perimeter would be 10 cm .

$\rule{225pt}{2pt}$

$\sf \: Now,\; let's\; find \: the \: Area .$

We know that the formula of Area to find the square is,

$\boxed{ \sf \longrightarrow \: Area = (side) {}^{2} }$

Note : The answer would always be in cm².

$\bf Step\; 1 :\rm Put\; the\; value \; of\; side \; of \; the\; square :$

$\sf\longrightarrow{Area} = (2.5) {}^{2} \: cm {}^{2}$

$\sf\longrightarrow{Area} = (2.5 × 2.5 ) \: cm {}^{2}$

$\bf \: Step\;2 : \rm Multiply :$

$\longrightarrow\sf \: Area = 6.25 \: cm {}^{2}$

Hence, the area of the square would be 6.25 cm².

$\rule{225pt}{2pt}$

I hope this helps!
