Answer:

2.5

Step-by-step explanation:

t = 0.25 $d^{1/2}$

Substitute d with 100

t = 0.25 x ( $100^{1/2}$ )

A number to the half power is equal to the square root of a number.

Square root of 100 is 10: $\sqrt{100} = 10$

t = 0.25*10

t = 2.5

Hope this helps :)

I'm confused on how to create ratios

Rzqust [24]

Answer:

Latoya:

cran : lem = 2 1/5 : 1 4/5

= 11/5 : 9/5

= 11 : 9

Lem : total = 9 : 20

Parker:

cran : lem = 2 1/2 : 3 1/2

= 5/2 : 7/2

= 5 : 7

Lem : total = 7 : 12

(b) The area of a rectangular painting is 7719 cm2.

Nataliya [291]

Given:

The area of a rectangular painting is 7719 cm²
Width of painting = 83cm

To Find?

Length of painting.

Solution:

Let length of painting be x cm

Using formula:

Area of rectangle = L × B

Where,

Length = x cm
Breadth = 73 cm

→ 7719 = x × 83

→ x = 7719/83

→ x = 93 cm

Hence,

Length of painting is 93cm

"if f(x)=x+1/x then the set of values for which f increases is"

Anettt [7]

The solution for this problem would be:
f'(x) = 1 - 1/x^2 = (x^2 - 1)/x^2
is positive where |x| > 1
hence (-inf, -1) and (1, inf) are the regions in which f' is positive and therefore f is increasing.
Therefore, the answer is (-infinity,-1] U [1,infinity).
