What is 36kg in the ratio 7:2

Mathematics
1 answer:
babymother [125]3 years ago
6 0

Answer:

28 Kg : 8 Kg

Step-by-step explanation:

Sum the parts of the ratio, 7 + 2 = 9 parts

Divide 36 Kg by 9 to find the value of one part of the ratio.

36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus

7 parts = 7 × 4 Kg = 28 Kg

2 parts = 2 × 4Kg = 8 Kg

36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg

VMariaS [17]

28.3

Step-by-step explanation:

the difference is the answer to a subtraction problem so we can plug in our numbers like this

25.6-(-2.7) which equals 28.3

a good thing to remember when subtracting negative numbers is that a positive and negative won't always make a negative like in this example

What is the equation in point−slope form of the line passing through (−3, −4) and (0, 2)?
Nana76 [90]

Answer:

y = 2x + 2

Step-by-step explanation:

To find the slope we do (Y1 - Y2)/(X1-X2) aka rise over run

So, m = (-4 - 2) / (-3 - 0)

m = 2

Now we have y = 2x +b

Notice one of our points is (0,2)

Since the x value of that point is 0, it is the y intercept.

In the slope intercept form b = y-intercept

Therefore b = 2

So, y = 2x + 2

Can you help me please??
dusya [7]

Answer:

y = \frac{4}{5}x+\frac{54}{5}

Step-by-step explanation:

Equation of a line has been given as,

y=\frac{4}{5}x+\frac{3}{5}

Here, slope of the line = \frac{4}{5}

y-intercept = \frac{3}{5}

"If the two lines are parallel, there slopes will be equal"

By this property slope of the parallel line to the given line will be equal.

Therefore, slope 'm' = \frac{4}{5}

Since, slope intercept form of a line is,

y = mx + b

Therefore, equation of the parallel line will be,

y = \frac{4}{5}x+b

Since, this line passes through a point (-6, 6),

6 = \frac{4}{5}(-6)+b

6 = -\frac{24}{5}+b

b = 6+\frac{24}{5}

b = \frac{30+24}{5}

b = \frac{54}{5}

Equation of the parallel line will be,

y = \frac{4}{5}x+\frac{54}{5}
