a rectangular field is 0.35 kilometers long and 0.3 kilometers wide. What is the area of the field in square meter

2 answers:

5 0

Remember that the formula for area for a rectangle is A=LW so knowing this
L= 0.35km
W=0.3
So 0.35 times 0.3 is equal to 0.105,
A= 0.105

Area is base times height, 0.3 times 0.35 is 0.105. Hope this helps!!!

HOW DO U DO THIS!?<br><br>2x+3=13

Soloha48 [4]

Answer:

x = 5

Step-by-step explanation:

Solve for x:

2 x + 3 = 13

Hint: | Isolate terms with x to the left hand side.

Subtract 3 from both sides:

2 x + (3 - 3) = 13 - 3

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

2 x = 13 - 3

Hint: | Evaluate 13 - 3.

13 - 3 = 10:

2 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 10 by 2:

(2 x)/2 = 10/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = 10/2

Hint: | Reduce 10/2 to lowest terms. Start by finding the GCD of 10 and 2.

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

How to solve ,step by step

Serggg [28]

Answer:

gradient = slope = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ = $\frac{rise}{run}$

Slope intercept Form equation : y = mx + b

m = slope or gradient

b = y - intercept ( where the line crosses the y = axis)

x and y = are place holders for a coordinate pair that makes the equation true

c) y = -6x + 8

The -6 is the m. It's the slope or gradient.

the + 8 is the b. It's the y- intercept.

d) y = 4

This is a horizontal line. It intercepts the y-axis at 4.

That means the 4 is the y-intercept.

There is no x. That means the slope is 0. The line rises 0 as it runs left to right.

e) y -4x= 0

equation needs to be is standard form y = mx + b.

add 4x to both sides in order to isolate the y variable.

y = 4x + 0.

The slope or gradient is 4. The y - intercept is 0. The line crosses through the origin.

f) y -x = -8

Add x to both sides.

y = x - 8

There is one x. That means the gradient is 1. The y-intercept is the -8

g) y + 3x = 7

Subtract 3x from both sides.

y = -3x + 7

-3 = gradient. 7 = y-intercept.

h) y + $\frac{1}{2}$ x = -4

Subtract $\frac{1}{2}$ x from each side.

y = - $\frac{1}{2}$ x - 4

One last thing. If you are presented with an equation without a y, the gradient is 'undefined'.

example : x = 4

This a vertical line passing through 4 on the x-axis. There is no 'b' because its not crossing the y-axis.

Why is it 'undefined' ?

As the line rises it, it does not 'run' left or right. $\frac{rise}{0}$ . Zero can never, ever be in the denominator. Denominators can't be zero. That is why we say it's 'undefined'.

Hope this helps.

Mr. Roboto has bought a can of paint can you use 3/8 of it to paint a bookshelf in use 1/4 of its pink leg and he used some of i

NNADVOKAT [17]

Answer: Fraction of paint used for bird house = $\dfrac14$

Step-by-step explanation:

Let quantity of the total paint be 1.

Given: Fraction of paint to book shelf = $\dfrac38$

Fraction of Paint to leg = $\dfrac14$

Fraction of Paint left = $\dfrac18$

Let x= fraction of paint used for bird house.

Total paint = $\dfrac38 +\dfrac 14+\dfrac18+x=1$

$\Rightarrow\ \dfrac{3+2+1}{8}+x=1\\\\\Rightarrow\ \dfrac{6}{8}+x=1\\\\\Rightarrow\ x=1-\dfrac68\\\\\Rightarrow\ x=\dfrac{2}{8}=\dfrac14$

So, Fraction of paint used for bird house = $\dfrac14$
