Answer:

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

Step-by-step explanation:

Let's

p = area covered by a can of paint

W = the total area of the walls

n = number of paint cans to buy

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

That is,

n = W / p

If the total area of the walls = 100 m²

A can of paint covers 5 m². Find the number of cans of paint needed?

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

n = W / p

= 100 m² / 5 m²

n = 20 cans of paint

Solve for X in 3x/10+x/5=15 PLEASE SHOW WORK

Firlakuza [10]

Answer:

x=30

Step-by-step explanation:

10(3x/10) + 10(x/5) = 10(15)

3x + 2x = 150

5x = 150

(5x)÷5 = (150)÷5

x = 30

Find the perimeter of the figure.

Ksenya-84 [330]

Answer:

Well I’m not sure what you want but I’ll give you both,

The perimeter is 25 units

The area is 28.5 units ^2

Step-by-step explanation:

Well to find perimeter just count every unit which is what I did and got 25 units.

To find the area jsut split them into two shapes and find the area for both.

Triangle formula: bh/2

Rectangle: Lw

Well we have 3 for base and 3 for height.

3*3=9

9/2=4.5

4.5 is the triangle

We got 3 for width and 8 for length

3*8=24

24 is the rectangle

Add them up

24+4.5= 28.5

28.5 units

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 5 sin(xy), (0, 2) maximu

Ahat [919]

Answer with Step-by-step explanation:

We are given that

$f(x,y)=5 sinxy$

Point=(x,y)=(0,2)

We have to find the maximum rate of change of f at given point.

$f_x(x,y)=5ycos(xy)$

$f_x(0,2)=5(2)cos0=10$

$f_y(x,y)=5xcosxy$

$f_y(0,2)=5(0)cos0=0$

$\Delta f(0,2)=f_x(0,2)+f_y(0,2)=10i+0j$

Maximum rate of change of f at point (0,2)= $\mid \Delta f(0,2)\mid=\sqrt{x^2+y^2}$

Where x=Coefficient of i

y=Coefficient of j

By using the formula

Maximum rate of change of f at point (0,2)= $\sqrt{(10)^2+0}=10$

Direction of maximum rate of change of f= $\Delta\har{f}=\frac{\Delta f(0,2)}{\mid\Delta f(0,2)\mid}=\frac{10i}{10}=i$

The price of a dress was reduced from $40 to $30. By what percentage was the price of the dress reduced? STEP BY STEP

VARVARA [1.3K]

Answer:

The price was reduced by 25%

Step-by-step explanation:

Not sure how to go step by step on this, because it's kinda obvious once you think about it a bit. You need to find what percent of 40 that 10 equals (if that makes sense). So really it's just what percent of 40 equals 10? and since 10 is one fourth of forty, 1/4, then you convert that to percent: 25% (sorry if this made no sense, i'm not very good at explaining things)
