Answer:

16 units

Step-by-step explanation:

For a right triangle, a²+b²=c², where a and b are leg lengths, and c is the hypotenuse. Given one leg length and the hypotenuse, we can find the other leg length by plugging in our given information:

a²+b²=c²

12²+b²=20²

144+b²=400

b²=256

b=16

Therefore, the missing leg length is 16 units.

The graph represents function 1, and the equation represents funtion 2:
horsena [70]

Answer:

8

Step-by-step explanation:

we know that

The rate of change of a linear equation is a constant that is the same that the slope

step 1

we have

The equation of the graph (function 1) is equal to

y=4

Is a horizontal line

The slope is equal to zero

so

The rate of change of function 1 is zero

step 2

The equation of the function 2 is

y=8x+12

This is a linear equation in slope intercept form

where

the slope is equal to m=8

so

The rate of change of function 2 is 8

therefore

The rate of change of function 2 is 8 more than the rate of change of function 1

1. If a tank leaks 10 mL of fluid each hour, how long will it take to fill up a one liter jar?
AnnZ [28]
Q1. The answer is 100 hours


10 ml is for 1 hours
1l is for x hours
1l = 1000 ml

So, make a proportion: 
10 ml is for 1 hours
1000 ml is for x
10 ml : 1h = 1000 ml : x
x = 1h * 1000 ml : 10 ml = 100 hours



Q2. The answers are:

1. kg - measurement of mass
2. cm² - measurement of area
3. L - measurement of volume (1L = 1 dm³)
4. m - measurement of length

Write a linear function f with the values f(0)=−3 and f(7)=11 <br> A function is f(x)=
Rudik [331]

Answer:

f(x) = 2x - 3

Step-by-step explanation:

x    y

0  -3

7   11

when x = 0, y = -3.  When x increases by 7, y increases by 14, or when x increases by 1, y increases by 2.

Given sets X, Y, Z, and U, find the set Xn(X - Y) using the listing method.
Aliun [14]

Answer:

{f, a}

Step-by-step explanation:

Given the sets:

X = {d, c, f, a}

Y = {d, e, c}

Z ={e, c, b, f, g}

U = {a, b, c, d, e, f, g}

To obtain the set X n (X - Y)

We first obtain :

(X - Y) :

The elements in X that are not in Y

(X - Y) = {f, a}

X n (X - Y) :

X = {d, c, f, a} intersection

(X - Y) = {f, a}

X n (X - Y) = elements in X and (X - Y)

X n (X - Y) = {f, a}

Rachel really wants to purchase a new skateboard and her mother has agreed to give her a weekly allowance that she can save unti
Slav-nsk [51]

Answer:

Step-by-step explanation:

10x+ 150=220 is the equation for the second plan you subtract 150 from 220 to get 70 and divide that by 10 and you get 7 which is the number of weeks it'll take

220/25=x

So for this one it'll take 8.8 weeks to get enough money and you divide 220 by the amount which is 25 to get 8.8 the number of weeks I'll take

I dont understand what the second one is asking so sorry dude but I think that's right
