The number of girls is 9 :) you add the two ratio numbers to equal 5 you then divide the 15 children by the ratio of 5, which is 3. you then times 2x3 and 3x3 to get the boy and the girls numbers which are 6 &9 so the number of girls is 9

finlep [7]

Answer:

D

Step-by-step explanation:

you have to multiply .79 to both a and 1.2. A is wrong because it's saying we need to multiply .79 to 1.2lb. which is the weight of oranges and the total cost of apples and oranges which is 6.27.

Find u, v , u , v , and d(u, v) for the given inner product defined on Rn. u = (0, −4), v = (5, 3), u, v = 3u1v1 + u2v2
tigry1 [53]

Answer:

=-12

d(u,v)=2\sqrt{31}

Step-by-step explanation:

We are given that inner product defined on R_n

=3u_1v_1+u_2v_2

u=(0,-4),v=(5,3)

We have to find the value of <u,v> and d(u,v)

We have u_1=0,u_2=-4,v_1=5,v_2=3

Substitute the value then we get

=3(0\cdot5)+(-4)(3)=-12

Now, d(u,v)=\left \|v-u\right \|

Using this formula we get

d(u,v)=\left \| (5,7) \right \|=\sqrt{3(5)^2+(7)^2}=\sqrt{75+49}=\sqrt{124}

d(u,v)=2\sqrt{31}

What is the slope of this graph and what does the slope mean?
Alchen [17]

Answer:

3,500,000/ 13

It means every 13 years it grows 3,500,000.

Step-by-step explanation:

The slope is a ration of the vertical distance to the horizontal distance between any two points on the line.  This means count the up and down distance and the left and right distance between two points.

Find two points on the line that cross through the grid line intersections like here (200, 500,000) and (2013, 4,000000).

The vertical distance is 4,000,000 - 500,000 = 3,500,000.

The horizontal distance is 2013-2000 = 13.

Write a ratio or fraction between the two distances.

3,500,000/ 13

It means every 13 years it grows 3,500,000.
