Answer:

Rate

Step-by-step explanation:

The rate of one quantity with another quantity (usually of different units) is the ratio that compares those two quantities. In other words, a rate is a comparison of two quantities of different units in ratio form. For example;

We know that velocity is the rate at which distance changes with time. This means that velocity is a rate comparing two different quantities which are distance and time which both have different units. Distance has an S.I unit of meters(m) while time has an S.I unit of seconds(s). This can be written as follows;

Velocity = distance : time or \frac{distance}{time}

Answer:

Rate

Step-by-step explanation:

Rate is basically also a ratio. but it is the comparing of two different quantities with different units.

As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.

for example:

When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.

20 meters : 15 seconds

thus the lowest form of this relationship will be:

4 meters : 3 seconds

when i write it in Decimal form it becomes :

Ans : 1.33 meters/second   (Distance per unit time)

As this ratio have remaining units thus it is referred to as "RATE".

Pls help for number 6

A: 45x + 30y = 1350
Since we don’t know how many adults and children are in the group, we use x and y

b: x-intercept= 30 y-intercept=45
To find the x-intercept you need to isolate the variable. 45x/45 = x
Then you do the same thing to the other side. 1350/45 = 30
So x=30
Same thing with the y-intercept.
30y/30 = y 1350/30 = 45
y=45 (Not really sure what it means by “what they represent” but I thinks it’s that there are 30 adult tickets and 45 children tickets )

c: so our points are (30,0) and (0,45) so you would graph that.
To find how many children tickets were bought if there were 20 adult tickets just look at the photo I put. I don’t know how to explain this.


Hope this helps

6) find HJ<br> 8)find IK
Anastasy [175]

Answer:

HJ = 17

IK = 30

Step-by-step explanation:

to find HI :

GH : 2

HI : ?

IJ : 12

GI : 7

HI = GI - GH

HI = 7- 2

HI = 5

HI + IJ = HJ

5 + 12 = HJ

17 = HJ

To find IK

IJ = ?

JK = 12

KL = ?

IL = 49

JL = 31

To find IK we need to find KL and IJ

KL = JL - JK

KL = 31 - 12

KL = 19

IJ = IL - (JK + KL)

IJ = 49 - 31

IJ = 18

IK = IJ + JK

IK = 18 + 12

IK = 30

tatuchka [14]

Answer:

61°

this triangle is split in half and forms 2 triangles. These triangles must be congruent since they are each excatly half of this rectangle

Therefore, <2 is going to be equal to the m< the corresponding angle in the other triangle. <2 = 61°

<2 is also equal to 61° by the interior angles theorem

Answer my math question I asked so many times I lost most of points by
kumpel [21]

Answer:

i think ur in a higher grade then me but im good w/ equations so OoOO0p

Step-by-step explanation:

equation: y = x - 6 + x^2

(6,0) (7,1) (8,4) (9,9)

I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.
