The mean length of 6 childrens' big finger is 9cm. The mean length of 4 adults' big finger is 9.7cm. What is the mean length (rounded to 2 DP) of these 10 people's big finger?

Answer:

300%

Step-by-step explanation:

To find percent change we need to use this formula:

[tex]change = \frac{Amount of change}{Original} * 100[/tex]

To find the amount of change we need to minus 50 from 200:

200 - 50 = 150

Now that we have the amount of change we can plug it in to the equation with the original amount (50):

[tex]change = \frac{150}{50} = 3 * 100 = 300[/tex]

Therefore, the percent of change is 300%.

I hope this helps!!

Answer:

-3

Step-by-step explanation:

Y = mx + c

m is the slope or the gradient and b is the y-intercept.

m = 5-8 / -6 - -7

m = -3

Given:

Point = (3,4)

Slope : m = -z

To find:

The point slope formula.

Solution:

Point slope form: If a line passes through the point [tex](x_1,y_1)[/tex] and having slope m, then the point slope form of the line is

[tex]y-y_1=m(x-x_1)[/tex]

The line passing through the point (3,4) and having slope -z.

Putting [tex]x_1=3,y_1=4, m=-z[/tex], we get

[tex]y-4=-z(x-3)[/tex]

Therefore, the required point slope form is [tex]y-4=-z(x-3)[/tex].

Answer:

16(4b - 1c)

Step by step explanation:

The gcf is 16.

so you divide 16 by both numbers

and

you have to start forming the equation

Step-by-step explanation:

4/7 of distance = 2/9 of potion

=> 7/7 of distance = 2/9 * (7/4) = 7/18 of potion.

The dragon has used 7/18 of the potion for the journey, and only have 11/18 of it left.

Amount left = 630 ounces * 11/18 = 385 ounces.

Answer:

number of green ÷ total number of marbles

times by

number of red ÷ total number of marbles left

so

(3/9) × (2/8) = (1/12)

Answer:

Step-by-step explanation:

m<7=3x-10

m<3=2x+5

we know that from corresponding angle axiom that

m<7=m<3

3x-10=2x+5

3x-2x=10+5

x=15

m<7=45-10=35,  

m<7=m<1=35

Given:

A profit of 60$.

To find:

An integer for the given situation.

Solution:

The given situation is "A profit of 60$".

We know that,

1. Negative integers are used to represent loss.

2. Positive integers are used to represent profit.

Here, the profit is 60$. So, the sign of required integer must be positive and the value of the integer is 60.

Therefore, the required integer is 60.

Step-by-step explanation:

Using synthetic division of polynomials 3x⁴-2x²+4x+9÷x+2. Rewrite the dividend as 3x⁴+0x³-2x²+4x+9

2 | 3 0 -2 4 9

| 6 -12 20 -32

3 -6 10 -16 41

So the quotient is 3x³-6x²+10x-16 with a remainder of 41

Therefore, 3x³-6x²+10x-16+(41/x+2)

x=10

Step-by-step explanation:

2x-10=10

2x=20

x=10

Answer:

x=10

Step-by-step explanation:

2(x - 5) = 10

You would first multiply 2 by x and 5

2x-10 = 10

then you would add ten to both sides

2= 20

then you would divide 2 by 20

x=10
