8 0

A unit fraction is a fraction where the denominator is one, so the easiest way to write 4/5 as a sum of unit fractions is to use 1/5.
So the answer would be 1/5+1/5+1/5+1/5.
Add up all the numerators and put that over their like denominators to get 4/5!

Answer:

$\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}$

Step-by-step explanation:

we know that

A unit fraction is a fraction with a numerator equal to $1$

In this problem we have

$\frac{4}{5}$

rewrite as a sum of unit fractions

$\frac{4}{5}=4*\frac{1}{5}=\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}$

Sanjay bought a basket of oranges, a basket of apples,a basket of mangoes and a basket of peaches.He paid a total of Rs 790 for

Margarita [4]

Let a the price of a basket of oranges be O, that of a basket of apples A, a basket of mangoes M and a basket of peaches P, then
O + A + M + P = 790 . . . (1)
M - 4 = P + 7 = 3O = A/2 . . . (2)
From (2), we have:
M = P + 11
O = (P + 7)/3
A = 2P + 14

Substituting for M, O and A into (1), gives:
(P + 7)/3 + 2P + 14 + P + 11 + P = 790
P + 7 + 6P + 42 + 3P + 33 + 3P = 2370
13P + 82 = 2370
13P = 2288
P = 176

Therefore, the price of a basket of peaches is Rs176.

AleksAgata [21]

Answer:

Over 2 oz. Class A-II felony

Step-by-step explanation:

One would need to carefully weigh the material.*

0.06 kg ≈ 2.12 oz

Note that .06 kg is 1 significant figure, so this rounds to 2 oz (1 significant figure). Given the precision of the reported weight, there is insufficient precision to say the amount is actually over 2 oz.

If you take the numbers at face value, the suspect is in possession of over 2 oz, so will be charged with a Class A-II felony.

_____

* 2.00 ounces translates to about 0.0567 kg, which rounds to 0.06 kg.

The equation y=−0.0088x2+0.79x+15 models the speed x (in miles per hour) and average gas mileage y (in miles per gallon) for a v

Neko [114]

we are given

$y=-0.0088x^2+0.79x+15$

where

y is average gas mileage in miles per gallon

x is speed in miles per hour

we have to find average gas mileage at a speed of 60 miles per hour

so, we have

$x=60mph$

now, we can plug it and find y

$y=-0.0088(60)^2+0.79(60)+15$

we get

$y=30.72$

so,

the best approximate for the average gas mileage at a speed of 60 miles per hour is 30.7 mi/gal...........Answer

Gekata [30.6K]

Answer:

$\text{A and B are independent events}, P(A|B)=P(A)=0.16$

Step-by-step explanation:

First of all we need to know when does two events become independent:

For the two events to be independent, $P(A|B)=P(A)$ that is if condition on one does not effect the probability of other event.

Here, in our case the only option that satisfies the condition for the events to be independent is $P(A|B)=P(A)=0.16$ . Rest are not in accordance with the definition of independent events.
