Answer:
Claire borrowed $500 from her father.
Step-by-step explanation:
Interest = $90
p = ?
r = 6% or 0.06
t = 3
Simple interest formula is :
![I=p\times r\times t](https://tex.z-dn.net/?f=I%3Dp%5Ctimes%20r%5Ctimes%20t)
Putting values in formula we get;
![90=p\times0.06\times3](https://tex.z-dn.net/?f=90%3Dp%5Ctimes0.06%5Ctimes3)
![90=0.18p](https://tex.z-dn.net/?f=90%3D0.18p)
p = $500
Hence, Claire borrowed $500 from her father.
Answer:
The cost of the mug is of $6.50.
Step-by-step explanation:
The cost of the mug and r refills is given by the following equation:
![C(r) = 2.3r + 6.5](https://tex.z-dn.net/?f=C%28r%29%20%3D%202.3r%20%2B%206.5)
Cost of the mug:
The cost of the mug is found when no refills are bought, that is, C when
, which is ![C(0)](https://tex.z-dn.net/?f=C%280%29)
![C(0) = 2.3*0 + 6.5 = 6.5](https://tex.z-dn.net/?f=C%280%29%20%3D%202.3%2A0%20%2B%206.5%20%3D%206.5)
The cost of the mug is of $6.50.
Answer:
The price of the burrito is $3.5 and the price of the taco is $2.5.
Step-by-step explanation:
2x+5y=19.5
5x+2y=22.5
------------------
5(2x+5y)=5(19.5)
-2(5x+2y)=-2(22.5)
-----------------------------
10x+25y=97.5
-10x-4y=-45
-----------------------
21y=52.5
y=52.5/21=2.5
2x+5(2.5)=19.5
2x+12.5=19.5
2x=19.5-12.5
2x=7
x=7/2=3.5
x=3.5, y=2.5
The price of the burrito is $3.5 and the price of the taco is $2.5.
Step-by-step explanation:
![63 + x = 180 \\ x = 180 - 63 \\ x = 117 \\ so \: the \: supplemetary \: angle \: of \: 63 \: deg \: is \: 117 \: deg.](https://tex.z-dn.net/?f=63%20%2B%20x%20%3D%20180%20%5C%5C%20%20x%20%3D%20180%20-%2063%20%5C%5C%20%20x%20%3D%20117%20%5C%5C%20so%20%5C%3A%20the%20%5C%3A%20supplemetary%20%5C%3A%20angle%20%5C%3A%20of%20%5C%3A%2063%20%5C%3A%20deg%20%5C%3A%20is%20%5C%3A%20117%20%5C%3A%20deg.)
