Answer:
vertically opposite angle
Step-by-step explanation:
Answer:
trapezoid
Step-by-step explanation:
There is only one group of shapes that could be a trapezoid
A square, a rectangle, a rhombus, a trapezoid, a kite, and other 4-sided shapes fall under the category of quadrilateral
A rhombus, a parallelogram, and a square are all rhombuses
Answer:
One
Step-by-step explanation:
9/sin(34) = 6/sinC
sinC = 0.372795269
C = 21.9, 158.1
Since 158.1 + 34 = 192.1 > 180
It will not form a triangle
So,
Only one triangle with angle 21.9° at C
Answer:
Step-by-step explanation:
1/8 = 1/9 + x ...multiply by LCD of 72
9 = 8 + 72x
9 - 8 = 72x
1 = 72x
1/72 = x
1/8 = 1/10 + x....multiply by 40
5 = 4 + 40x
5 - 4 = 40x
1 = 40x
1/40 = x
1/8 = 1/11 + x....multiply by 88
11 = 8 + 88x
11 - 8 = 88x
3 = 88x
3/88 = x
can all unit fractions be made in more then 1 way like this ?
not to sure because that last one....because it has been that a unit fraction is the outcome of adding together 2 unit fractions...but that last one...3/88 is not a unit fraction
Hello! I can help you with this!
a. The function that would best represent Samantha's account is f(5) = 500(1 + 0.04)^5. This is because $500 is the principal, the interest rate is 4%, and we're looking for the amount in the savings account 5 years later.
b. Okay. 1 = 0.04 is 1.04. 1.04^5 is 1.216652902. It's a long decimal, but don't delete it. Multiply that decimal by 500 and you get 608.32645 and other numbers behind it or 608 when rounded to the nearest dollar. Samantha will have about $608 in her savings account in 5 years.
Note: The formula goes like this: f(x) = P(1 + r)^x. This means, you add 1 and the simple interest rate in decimal form together and raise that up by the exponent. There is no shortcuts for this, so you'll have to use the calculator. There will be a very long decimal, but don't clear it. Instead, multiply it by the principal to get the answer. It seems very complicating, but if you do this right, it gets easier overtime and you'll make less errors. There are more complex problems out there, so this formula is very important, but it was kept simple for this question.
