Answer:

Step-by-step explanation:

a)1) As denominators are same, keep the same denominator for the result also

Add the numerators and write the new numerator.

$\frac{3y}{4}+\frac{5y}{4}=\frac{3y+5y}{4}=\frac{8y}{4}$ = 2y

20 Reduce to simplest form by dividing the numerator and denominator by GCF

Answer:

I FOUND IT ACTUALY 22.857 lacs $2,285,714

Step-by-step explanation:

do the formula

is/of = %/100

$\frac{17.5}{100} = \frac{4}{x}$

100*4=400

400/17.5=22.857

Tiffany and Dion are having a walking race. The equation and graph show the distance each person is from the starting line,

satela [25.4K]

Answer:

Step-by-step explanation:

Tiffany's distance is defined by the equation,

d = 2.5t

Here, d = distance of Tiffany from the starting line

t = time

a). d = 2.5t

$\frac{d}{t}=2.5$

Tiffany's rate = 2.5 yards per second

b). Since, slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of the line passing through two points (0, 10) and (10, 35)

= $\frac{35-10}{10-0}$

= 2.5 yards per second

Dion's walking rate = 2.5 yards per second

Equation that defines the distance of Dione,

d = mt + b

Here, m = rate of the walking by Dione

b = y-intercept

Hence, equation will be,

d = 2.5t + 10

c). If d = 60 yards

For Tiffany,

d = 2.5t

60 = 2.5t

t = 24 seconds

For Dion,

d = 2.5t + 10

60 = 2.5t + 10

2.5t = 50

t = 20 seconds

Therefore, Dion will take less time and finish first.

If one of the roots of the equation x² – 4x + k = 0 exceeds the other by 2, then find the roots and determine the value of k.

Verizon [17]

Step-by-step explanation:

the solutions for a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = -4

c = k

x = (4 ± sqrt(16 - 4k))/2 = 2 ± sqrt(4 - k)

x1 = 2 + sqrt(4 - k)

x2 = 2 - sqrt (4 - k)

x1 = 2 + x2

2 + sqrt(4 - k) = 2 + 2 - sqrt(4 - k)

2×sqrt(4 - k) = 2

sqrt(4 - k) = 1

4 - k = 1

k = 4 - 1 = 3

x1 = 3

x2 = 1
