7 0

Step-by-step explanation:

sol;

l=5w

area=l*w

or,45=5w*w

or,45=5w2

or,45\5=w2

0r\sqrt{9}=w

or,3=w

again,

l=5w

l=5*3

l=15

Therefore, length is 15 inch and width is 3 inch.

The length of one of the equal sides of an isosceles triangle is 4 cm. If its base is 2 cm, then what is its area?​
TEA [102]

Answer:

A = 1/2bh

b = 2cm

h will be found using the side of the triangle with Pythagoras theorem

h² + 1² = 4²

h² = 15

h = √15 cm

then,

A = <u>2</u><u>*</u><u>√</u><u>1</u><u>5</u><u> </u>

2

A = √15cm²

I need help on question #20 please!!!! Also show work!!! And tell me why the answer to the problem is correct. THANK YOU!!!

1188 = π<em>r</em>²<em>h</em>

For the formula to solve for <em>h, </em>you have to change the equation to:

<em>h </em>= 1188/π<em>r</em>²

which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.

because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)

Since you don't know the radius, you can't simplify this equation.

The answer is <em>h </em>= 1188/π<em>r</em>²

My divisor is 4/7 and my quotient is 7/24. what is the dividend
kompoz [17]

Answer:

1/6.

Step-by-step explanation:

x / 4/7 = 7/24  where x is the dividend.

7x/4  = 7/24

Cross multiply:

7x * 24 =  4*7

x = 28/(7*24)

= 28/168

= 1/6.
