Answer: He will travel \frac{1}{4} miles in 1 hour.

Step-by-step explanation:

Let's use the rule of 3.

I'm going to type the time info in the left side, and the distance in the right side.

\frac{\frac{2}{3}h }{1h} =\frac{\frac{1}{6} mi}{xmi}

x=\frac{\frac{1}{6}*1 }{\frac{2}{3} }

x=\frac{\frac{1}{6} }{\frac{2}{3} }

Multiply by the reciprocal of the fraction in the denominator.

x=\frac{1}{6}*\frac{3}{2}

x=\frac{1}{4}

Fern knitted 20 scarves over 5 nights. After 8 nights of knitting, how many scarves would fern have made in total.
Studentka2010 [4]

Answer:

Fern will knit 32 scarves in 8 nights.

Step-by-step explanation:

Number of scarves knitted by Fern in 5 night = 20

Relation between number of scarves knitted and number of nights is proportional,

Therefore, Number of scarves knitted (s) ∝ Number of nights spent to knit the scarves (n)

s ∝ n

s = kn

k = \frac{s}{n}

Here, k = proportionality constant

For s = 20 and n = 5,

k = \frac{20}{5}

k = 4 scarves per night

For 8 nights, by using the same proportionality rule,

k = \frac{s}{8}

4 = \frac{s}{8}

s = 32 scarves

Therefore, Fern will knit 32 scarves in 8 nights.

Can someone help me please
Dafna1 [17]

Answer:

none

Explanation:

Fill in each option for x individually.

I)     9 \leq -10 - 4(-1)  

II)    9 \leq -10 - 4(-3)  

III)   9 \leq -10 - 4(-2)

Then, simplify the right side of each inequality.

I)    9 \leq -6

II)   9 \leq 2

III)  9 \leq -2

Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.

What is the quadratic equation that has roots of ,-3 And 2/5​
prohojiy [21]

Answer: 5x² + 13x - 6 = 0

Step-by-step explanation:

Represent the roots with X i.e.

X = -3 ; X = 2/5

Moving the values of X over the equator we have;

X + 3 = 0 ; 5X - 2 = 0

Equating both equations to zero we can obtain;

(X + 3)(5X - 2) = 0

Opening the brackets we get;

5x² - 2x + 15x - 6 = 0

The  result of the above equation gives;

5x² + 13x - 6 = 0
