The correct question is
The local currency it gives is a total of 275 Yuan. <span>If the yuan is worth 6.58 to a US$, what would the price to a US$ be if the yuan changed to 6.25
The </span><span>options are A)$2.21 B)$2.50 C)$13.31 D)$41.79 E)$44.00
we know that
</span><span>at the current exchange rate give (6.58)
</span>if 1 usd-----------------> 6.58 yuan
X usd------------------> 275 yuan
X=275/6.58------------> X=41.79 usd
at the current exchange rate give (6.25)
if 1 usd-----------------> 6.25 yuan
X usd------------------> 275 yuan
X=275/6.25------------> X=44 usd
so
the change in price in US$ would be [44-41.79]=US$2.21
the answer is the option
A)$2.21
Answer:
x^2+y^2=25
Step-by-step explanation:
For my graphing utility, entering the given equation will generate the required graph. (The parentheses are not needed, but do no harm.)
Answer:
A = π · (r²)
Step-by-step explanation:
π · r² is the area of a circle.
While π · r² · h can also give you the radius, it can only do so for the Volume 
, not the Area 
.
doesn't really apply for a circular object, as it requires the length and width. For circular objects, both are equal to the diameter of the object, and 2² · r² · h does not equal the Volume.
π · r³ seems awfully like the volume of a sphere, but there's something missing. The true volume of a sphere is 
· π · r³, not π · r³.
only applies for triangles.
Answer: The answer is option C: 10cm, 6cm and 8cm
Step-by-step explanation: A right angled triangle has an hypotenuse (the longest of all three sides) facing the 90 degree angle. Also a right angled triangle can be solved by means of the Pythagoras theorem which states that;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse (10cm) and AB (6cm) and BC (10cm) are the other two sides.
If that is the case, we can insert the values as given in option C to know whether or not they make up a right angled triangle. Therefore
10^2 = 6^2 + 8^2
100 = 36 + 64
100 = 100
Therefore the side lengths 10cm, 6cm and 8cm satisfies the requirements for a right angled triangle
Answer:
The correct answer is +45; -18; -7.
Step-by-step explanation:
Parvana records the transactions for her bank account for the week .
On Monday, Parvana deposited $45. Thus Parvana made an addition of $45 in her account. Therefore a +45 integer is used to represent this transaction into her account.
On Tuesday she used her debit card to $18 for a new shirt. Thus Parvana made a deduction of $18 from her account. Therefore a -18 integer is used to represent this transaction into her account.
On Thursday she withdrew $7 from an ATM. Thus Parvana made a deduction of $7 from her account. Therefore a -7 integer is used to represent this transaction into her account.
Thus the integers +45; -18 and -7 are used to represent transactions in Parwana's account.
