Answer:

5/2 cups of warm water

Step-by-step explanation:

Recipe for homemade slime solution

Warm water : cups of soap

5/3 : 1/3

if she has 2/4 cup of soap how many cups of warm water will she need

Let

x = cups of warm water she will need

Warm water : cups of soap

x : 2/4

Equate the two ratios

5/3 : 1/3 = x : 2/4

5/3 ÷ 1/3 = x ÷ 2/4

Cross product

5/3 * 3/1 = x * 4/2

15/3 = x * 2

5 = 2x

Divide both sides by 2

x = 5/2 cups

She will need 5/2 cups of warm water

Which shows the correct substitution of the values a, b, and c from the equation 0 = 4x2 + 2x – 1 into the quadratic formula bel

Basile [38]

Answer:

x = StartFraction negative 2 plus or minus StartRoot 2 squared minus 4(4)(negative 1) EndRoot Over 2(4) EndFraction

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$4x^{2} +2x-1=0$

$a=4\\b=2\\c=-1$

substitute in the formula

$x=\frac{-2(+/-)\sqrt{2^{2}-4(4)(-1)}} {2(4)}$

therefore

x = StartFraction negative 2 plus or minus StartRoot 2 squared minus 4(4)(negative 1) EndRoot Over 2(4) EndFraction

Find the surface area of each figure. Round your answers to the nearest tenth, if necessary

Inga [223]

Let A be the surface area, b the base, h the height;

h₁=8.4 cm

h₂=7.8 cm

b= 9 cm

A= 3(1/2bh₁)+1/2 bh₂

A=3(1/2(9)(8.4))+1/2 (9)(7.8)

A= 148.5 cm³
