1 1/3 divided by 3/5 and i wil name brainliest

Answers

Answer 1
Answer:

Answer:

(20)/(9) or 2(2)/(9)  or 2(1)/(3)

Step-by-step explanation:

1(1)/(3) = (4)/(3) and (3)/(5)

to

(4)/(3) divided by (3)/(5)

                    ↑

flip the second number

(4)/(3) divided by (5)/(3)

but instead of divison it becomes multiplication,

(4)/(3) × (5)/(3)

=

(20)/(9)

Mixed number form is:

2(2)/(9)

or

Simplify:

2(1)/(3)
Answer 2
Answer:

Answer:

2 2/9

Step-by-step explanation:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

4/3÷3/5

Applying the fractions formula for division,

=4×5

3×3

=20/9

Simplifying 20/9, the answer is

=2 2/9

Graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4x
g(x) = 4x2

The 2 in the 2nd equation is supposed to be an exponent btw

Answers

Answer:

Hi,

The answer is (-0.383,1) and (2,∞).

Step-by-step explanation:

See the attachment.

g(x) is a parabolic function, and the Image is always ≥ 0.

f(x) is a exponential function, and the Image is always ≥ 0.

At x = -0.383 , g(x) = 0.588 and f(x) = 0.588.

For x=(-0.383, 1), g(x) is greater than f(x).

At x = 1, g(x) = 1 and f(x) = 1.

For x=(1, 2), f(x) is greater than g(x).

At x= 2, g(x) = 16 and f(x) = 16

For x=(2,∞), g(x) is greater than f(x)

The yard behind the Cindy’s house is rectangular in shape and has a perimeter of 72 feet. If the length l of the yard is 18 feet longer than the width w of the yard, what is the area of the yard, in square feet?

Answers

let
L----------> the length of the yard
W--------> the width l of the yard

we know that
the perimeter is equal to
P=2*[W+L]
72=2*[W+L] \n 36=W+L  --------> equation 1
L=W+18  ------> equation 2
substitute equation 2 in equation 1
36=W+18+W \n 36=2W+18 \n W=(36-18)/2
W=9 ft
L=W+18 \n L=9+18 \n L=27 ft

we know that
Area of the rectangular yard is equal to
A=L*W \n A=27*9 \n A=243 ft^(2)

Answer:

2187\text{ ft}^2

Step-by-step explanation:

Let l be the length and w be the width of yard behind Cindy's house.

We have been given that the length of the yard is 18 feet longer than the width of the yard. We can represent this information in an equation as:

l=w+18...(1)

We have been also given that the perimeter of the yard is 72 feet. Since perimeter of a rectangle is 2 times the sum of its length and width, so we can represent this information in an equation as:

2(l+w)=72...(2)

Dividing both sides of equation (2) by 2 we will get,

l+w=36...(2)

Substituting equation (1) in equation (2) we will get,

w+18+w=36

2w+18=36

2w+18-18=36-18

2w=18

(2w)/(2)=(18)/(2)

w=9

Upon substituting w=9 in equation (1) we will get,

l=9+18

l=27

\text{Area of rectangle}=l\cdot w

\text{Area of rectangle}=27\text{ yards}\cdot 9\text{ yards}

\text{Area of rectangle}=243\text{ yards}^2

Now, we need to convert the area of rectangle form square yards to square feet.

1\text{ yards}^2=\text{9 foot}^2

243\text{ yards}^2=243* \text{9 foot}^2

243\text{ yards}^2=2187\text{ foot}^2

Therefore, the area of yard behind Cindy's house is 2187 square feet.

If 5x + x² > 100, then x is not 10 8 7 9

Answers

We will solve the equation:
x^2+5x-100≥0 x_(12) = (-5\pm √(25+400) )/(2)= (-5\pm20.6)/(2)      x1≈-12.8   x2≈ 7.8
It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).
Answer: C) x ≠ 7
Thank you.

If inequality 5x + x² > 100, then x is not equal to 7.

The given inequality looks like you have a quadratic inequality that we have to solve,

5x + x² > 100

To determine which values of x will not satisfy this inequality,

We can use algebraic manipulation.

We can rewrite the inequality as,

x² + 5x - 100 > 0

Then, we can use the quadratic formula to find the roots of the equation, which are x = (-5 ± √(425)) / 2.

x ≈ -12.8 or 7.8

It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).

Hence, x ≠ 7
