13 cans of paint with 5/6 liters of paint in each were used to paint 4 identical cars. How can you calculate the amount of paint

brilliants [131]

Answer:

(B) 5/6 ·13÷4

(D) 5/6 · 13/4

Step-by-step explanation:

Amount of paint per can = $\frac{5}{6}$ liters.

Number of cans used to paint 4 cars = 13

Total amount of paint used for 4 cars = $13 * \frac{5}{6}$ liters.

= $\frac{13 * 5}{6}$ liters.

= $\frac{65}{6}$ liters.

Total amount of paint used for 1 car = $\frac{65}{6} \div 4$ liters.

= $\frac{65}{24}$ liters.

Of the given options, option B,C and D correspond to the same value.

F(x)=9÷4x-15 for x=4

enyata [817]

9/4x -15 for x=4

To find this answer you must plug the 4 everywhere the x is located.

(9/4)(4) -15

Multiply 9/4 by 4

(9/4) x 4 = 9

Now we take our 9 answer and add it to -15.

9-15 = -6

The answer is -6

For the other equation, you also must plug in 3 where ever x is located in the equation.

5/3x -3/5

(5/3)(3) -3/5

Multiply 5/3 and 3

(5/3) x 3 = 5

Take that answer of 5 and add -3/5

5- (3/5) =4 2/5

The answer to this equation would be 4 2/5 or 4.4

If point P is 4/7 of the distnace frm M to N, what ratio does the point P partiion the directed line segment from M to N

vredina [299]

Answer: 4:3.

Step-by-step explanation:

Given: Point P is $\dfrac{4}{7}$ of the distance from M to N.

To find: The ratio in which the point P partition the directed line segment from M to N.

If Point P is between points M and N, then the ratio can be written as

$\dfrac{MP}{MN}=\dfrac{MP}{MP+PN}$

As per given,

$\dfrac{MP}{MP+PN}=\dfrac{4}{7}\\\\\Rightarrow\ \dfrac{MP+PN}{MP}=\dfrac{7}{4}\\\\\Rightarrow\ \dfrac{MP}{MP}+\dfrac{PN}{MP}=\dfrac{7}{4}\\\\\Rightarrow\ -1+\dfrac{PN}{MP}=\dfrac{7}{4}\\\\\Rightarrow\ \dfrac{PN}{MP}=\dfrac{7}{4}-1=\dfrac{7-4}{4}=\dfrac{3}{4}\\\\\Rightarrow\ \dfrac{PN}{MP}=\dfrac{3}{4}\ \ \or\ \dfrac{MP}{PN}=\dfrac{4}{3}$
