Yolanda invested her savings in two investment funds. The $2000 that she invested in fund A returned a 4% profit. The amount that she invested in fund b returned a 1% profit. How much did she incest in fund b, if both funds returned a 2% profit

she invested $4000 in fund B.

Step-by-step explanation:

Let x represent the amount invested in fund B.

The $2000 that she invested in fund A returned a 4% profit. It means that the profit made from fund A is

4/100 × 2000 = 0.04 × 2000 = 80

The amount that she invested in fund b returned B 1% profit. It means that the profit made from fund B is

1/100 × x = 0.01x

if both funds returned a 2% profit, it means that the profit made from both accounts is

2/100 × (2000 + x) = 0.02(2000 + x)

= 40 + 0.02x

The expression becomes

80 + 0.01x = 40 + 0.02x

0.02x - 0.01x = 80 - 40

0.01x = 40

x = 40/0.01

x = 4000

step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
