Answer:

44%

Step-by-step explanation:

Solution:

Calculate percentage change

from V1 = 2000 to V2 = 1120

(V2−V1)|V1|×100

=(1120−2000)|2000|×100

= −8802000×100

= −0.44×100

= −44%change

Derrick had $100 to spend at a sporting goods store. He bought a pair of shorts for $11.36 and a pair of athletic shoes for $47.
olga_2 [115]

Answer:

$40.82

Step-by-step explanation:

Subtract $11.36 from $100 and you'll get $88.64 and then just subtract $47.82 and the answer is $40.82. Not sure if u know how to subtract but just line the decimals up and take the smaller number away from the bigger one so in this case it would just be 100-11.36=88.64 and since he spent more money it would be 88.64-47.82=40.82

Jasmine, Abby, and Amber had $865 altogether. Jasmine spent 2/5 of her money. Abby spent $40, and Amber spent twice as much as J
erastovalidia [21]

Answer:

288.333333333

Step-by-step explanation:

Me, personally am not great with math, but I can say you have to take $865 then take away $40 then decide how much they get apiece. to do that you must divide 865 from 3. afterwards you should take that number away from 865 remember that you are also taking away 40 then you have your final answer

Type the correct answer in each box.
Mariulka [41]

Answer:

(x-5)^2+(y+4)^2=100

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center and any point that lie on the circle is equal to the radius

we have the points

(5,-4) and (-3,2)    

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the values

r=\sqrt{(2+4)^{2}+(-3-5)^{2}}

r=\sqrt{(6)^{2}+(-8)^{2}}

r=\sqrt{100}\ units

r=10\ units

step 2

Find the equation of the circle

we know that

The equation of a circle in standard form is equal to

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center

r is the radius

we have

(h,k)=(5,-4)\\r=10\ units

substitute

(x-5)^2+(y+4)^2=10^2

(x-5)^2+(y+4)^2=100
