Cos = adjacent / hypotenuse

cos 25° = 4 / AB

cos 25° • AB = 4 / AB • AB

AB cos 25° ÷ cos 25° = 4 ÷ cos 25°

AB = 4/cos 25°

AB = 4.41 (nearest hundredth)

A potter uses three fifths of a pound to make a bowl, how many bowls can a potter make from ten pounds?

mestny [16]

One bowl needs 3/5 of a pound. Knowing that, we just need to find out how many 3/5s may fit in 10:

10 ÷ 3/5 =
= 10 * 5/3 =
= 50/3 =
= 16 2/3

Assuming the potter can't make a 2/3 of a bowl, he'll be able to make 16 bowls from 10 pounds.

The area of a rectangle is 259 cm2 and its lenght is 18.5 cm find

crimeas [40]

The breadth of rectangle is 14 cm

The perimeter of rectangle is 65 cm

<em><u>Solution:</u></em>

Given that,

Area of rectangle = 259 square centimeter

Length of rectangle = 18.5 cm

<em><u>The area of rectangle is given by formula:</u></em>

$Area\ of\ rectangle = length \times breadth$

<h3><u>Find the breadth:</u></h3>

Substitute the given values in above formula:

$259 = 18.5 \times breadth\\\\breadth = \frac{259}{18.5}\\\\breadth = 14$

Thus breadth is 14 cm

<h3><u>Find the perimeter:</u></h3>

The perimeter of rectangle is given by formula:

$Perimeter = 2(length + breadth)$

Substitute the given values in above formula:

$perimeter = 2(18.5+14)\\\\perimeter = 2(32.5)\\\\perimeter = 65$

Thus perimeter of rectangle is 65 cm

Claudia was cooking breakfast for her entire family she may double the amount of chocolate chip pancakes as she did regular panc

maw [93]

Answer: she made 36 chocolate chip pancakes, 18 regular pancakes, 9 blueberry pancakes and 27 sausagesl

Step-by-step explanation:

Let w represent the number of chocolate chip pancakes that she made.

Let x represent the number of regular pancakes that she made.

Let y represent the number of blueberry pancakes that she made.

Let z represent the number of sausages that she made.

she made double the amount of chocolate chip pancakes as she did regular pancakes. This means that

w = 2x

x = w/2

she only made half as many blueberry pancakes and she did regular pancakes. This means that

y = x/2

y = w/4

she made triple the amount of sausage as blueberry pancakes. This means that

z = 3y

z = 3w/4

if she cooked 90 items total, it means that

w + x + y + z = 90 - - - - - - - - - -1

Substituting x = w/2, y = w/4 and z = 3w/4 into equation 1, it becomes

w + w/2 + w/4 + 3w/4 = 90

Multiplying through by 4, it becomes

4w + 2w + w + 3w = 360

10w = 360

w = 360/10

w = 36

x = w/2 = 36/2

x = 18

y = w/4 = 36/4

y = 9

z = 3y = 3 × 9

z = 27
