Answer:

308 m^3

Step-by-step explanation:

The volume is given by

V = l*w*h where l is the length , w is the width and h is the height

V = 7*4*11

V = 308 m^3

Answer: 5/66 (I'm so sorry if this is wrong)

Step-by-step explanation: First you divide 10 and 3 3/4. 10 ÷ 3 3/4 = 0.0757575757575.

To turn that back into to a fraction, let X equal the decimal number

Equation 1:

X = 0.0757575757575 (1)

With 12 digits in the repeating decimal group,

create a second equation by multiplying

both sides by 1012 = 1000000000000

Equation 2:

1000000000000X = 75757575757.5757575757575 (2)

Subtract equation (1) from equation (2)

1000000000000X = 75757575757.5757575757575...

X = 0.0757575757575...

999999999999X = 75757575757.5

We get

999999999999X = 75757575757.5

Solve for X

X = 75757575757.5/999999999999

Multiply to eliminate 1 decimal places.

Here you multiply top and bottom by 1 10's

= 101 = 10

75757575757.5/999999999999 × 10/10 = 757575757575/9999999999990

Find the Greatest Common Factor (GCF) of 757575757575 and 9999999999990, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 151515151515,

757575757575/9999999999990 ÷ 151515151515/151515151515 = 5/66

Therefore

X = 5/66

In conclusion,

0.0757575757575 = 5/66

Find the coordinates of a point that divides the directed line segment PQ in the ratio 5:3. A) (2, 2) B) (4, 1) C) (–6, 6) D) (4

Yuri [45]

Answer:

The answer is explained below

Step-by-step explanation:

The question is not complete we need point P and point Q.

let us assume P is at (3,1) and Q is at (-2,4)

To find the coordinate of the point that divides a line segment PQ with point P at $(x_1,y_1)$ and point Q at $(x_2,y_2)$ in the proportion a:b, we use the formula:

$x-coordinate:\\\frac{a}{a+b}(x_2-x_1)+x_1 \\\\While \ for\ y-coordinate:\\\frac{a}{a+b}(y_2-y_1)+y_1$

line segment PQ is divided in the ratio 5:3 let us assume P is at (3,1) and Q is at (-2,4). Therefore:

$x-coordinate:\\\frac{5}{5+3}(-2-3)+3 \\\\While \ for\ y-coordinate:\\\frac{5}{5+3}(4-1)+1$

What's the answer for 41

NeTakaya

Pick any negative integer you want for x. Let's say we pick x = -10. Replace x with this value. So replace x with -10

x - y = -1
-10 - y = -1

Now isolate y. We do this in two steps. First we add 10 to both sides. Then we multiply both sides by -1

-10 - y = -1
-10 - y + 10 = -1+10
-y = 9
-1*(-y) = -1*(9)
y = -9

So one ordered pair is (x,y) = (-10,-9). There are infinitely many of these ordered pairs. Another ordered pair is (-11,-10) which is found following the same steps as shown above. The only thing that matter is that x-y is equal to -1. There are infinitely many ways to subtract two values to get -1.
