If we fill a wheelbarrow with dirt, it ways 60 pounds. When we only fill the wheelbarrow 1/4 full, it weighs 33 pounds. How much

irga5000 [103]

Answer:

24 pounds

Step-by-step explanation:

Let's call the weight of the empty wheelbarrow X, and the weight of dirt to fill the wheelbarrow Y.

So, we can formulate the following equations:

X + Y = 60

X + (1/4)*Y = 33

Subtracting the second equation from the first one, we have:

3/4 * Y = 27

Y = 27 * 4 / 3 = 36

Now, we can calculate X:

X + 36 = 60

X = 24 pounds

Find the value of x, y, and z in the image below.

Yakvenalex [24]

Answer:

Step-by-step explanation:

y=18°

x=64°

x+y+z=180

64+18+z=180

82+z=180

z=180-82=98°

Graph this equation of a circle?<br>I'm stuck and I don't know how to approach this math problem.

Soloha48 [4]

First use the distance formula to find the radius of the circle:
d= $\sqrt{ ( x_{2}- x_{1}) ^{2}+ ( y_{2}- y_{1}) ^{2} }$

d= $\sqrt{ (-1-23)^{2}+ (5--2)^{2} }$

d= $\sqrt{ (-24)^{2}+ (7)^{2} }$

d= $\sqrt{ (-24+7)^{2} }$

d= $\sqrt{ (-17)^{2} }$

d=|17|
d=17

Next, find the equation of the circle (use the first picture):
(x+1)^2+(y-5)^2=17^2

Finally, input the equation into a graphing calculator:
