Answer:

65 cm

Step-by-step explanation:

Remember that

1\ m=100\ cm

step 1

Convert 2.5 m to cm

2.5\ m=2.5(100)=250\ cm

step 2

To find out how much of the initial long pipe is left, subtract the lengths of 60 cm, 35 cm and 90 cm from the initial long pipe

250-(60+35+90)=250-185=65\ cm

Solve for the indicated variable. Include all of your work in your answer. Submit your solution.
levacccp [35]

Answer:

The answer is L=\frac{A}{W}

Step-by-step explanation:

In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.

In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.

A=LW

We divide each side by "W":

\frac{A}{W}=\frac{LW}{W}

We simplify the "W" in the right side:

\frac{A}{W}=L

Finally, the solution for "L" is :

L=\frac{A}{W}

Question 1
ASHA 777 [7]
Question 1 Simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). If the final answer is written in the form Ax2 + Bx + C, what is the value of B?

Solution:

5x^2 + 3x + 4 - 2x^2 + 6x - 3 = 3x^2 + 9x + 1

Then, B = 9

Question 2
Simplify: (3x2 − 2) + (2x2 − 6x + 3)

5x2 − 6x + 1

5x2 − 6x − 1

x2− 6x + 1

5x2 − 8x + 3

Solution:

3x^2 - 2 + 2x^2 - 6x + 3 = 5x^2 - 6x + 1

Question 3
A sports company conducted a road test of a new model of a geared bike. The test rider cycled (3x - 2) miles on a flat road, (x2 - 5) miles uphill, and (2x + 7) miles downhill. Which simplified expression is equivalent to the total distance, in miles, for which the bike was tested?

x2 - x

x2 + 5x

x2 − x + 14

x2 + 5x + 14

(3x - 2) + (x2 - 5) + (2x + 7) = 3x - 2 + x^2 - 5 +2x + 7 = x^2 + 5x

Question 4
Simplify: (4x − 6) − (5x + 1)

x + 7

−x + 7

x − 7

−x − 7

(4x − 6) − (5x + 1) = 4x - 6 - 5x - 1 = -x -7

Question 5
Simplify the following expression: (x + 6y) - (3x − 10y). If the final answer is written in the form Ax + By, what is the value of A?

(x + 6y) - (3x − 10y) = x + 6y - 3x + 10y = -2x + 16y

A = -2

Question 6
Simplify: (3x − 5) + (3x + 6)

6x − 1

1

6x − 11

(3x − 5) + (3x + 6) = 3x - 5 + 3x + 6 = 6x + 1

The sum of the measures of two of the angles formed by the intersection of two lines is 114°. Find the measures of all angles. I
JulijaS [17]

Answer:

Measures of all angles are 57°, 57°, 123°, 123°

Step-by-step explanation:

Given:

Sum of two angles = 114°

Find:

Measures of all angles

Computation:

Sum of all 4 angles = 360°

Sum of remain 2 angles = 360° - 114°

Sum of remain 2 angles = 246°

So, first two angles = 114° / 2 = 57°

Second two angles = 246° / 2 = 123°

So, measures of all angles are 57°, 57°, 123°, 123°
