Answer:
1 1/5 or 12/10
Step-by-step explanation:
310+910=?
The two fractions have like denominators so you can add the numerators.
Then:
3+910=1210
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 12 and 10 using
GCF(12,10) = 2
12÷210÷2=65
The fraction
65
is the same as
6÷5
Convert to a mixed number using
long division for 6 ÷ 5 = 1R1, so
65=115
Therefore:
310+910=1 1/5
Hope this Helps!
Answer:
1. ¹⁰/₁₂ and ⅚;
2. ⁸/₁₂ and ⁴/₆;
3. ⁶/₁₂ and ³/₆
Step-by-step explanation:
The question is asking what fractions of 12 are equivalent to fractions of some smaller number.
Derek cut his pizza into 12 slices. Let's say that Ryan cut his into 6 slices.
Scheme 1
Derek eats 10 slices, and Ryan eats 5 (Fig A
)
Then Derek has eaten ¹⁰/₁₂ = ⅚ of a pizza and Ryan has eaten ⅚ of a pizza.
They each have ⅙ of a pizza left over.
The fractions here are ¹⁰/₁₂ and ⅚.
Scheme 2
Derek eats 8 slices, and Ryan eats 4 (Fig. B)
Then Derek has eaten ⁸/₁₂ = ⅔ of a pizza and Ryan has eaten ⁴/₆ = ⅔ of a pizza.
They each have ⅓ of a pizza left over.
The fractions here are ⁸/₁₂ and ⁴/₆.
Scheme 3
Derek eats 6 slices, and Ryan eats 3 (Fig. C)
Then Derek has eaten ⁶/₁₂ = ½ of a pizza and Ryan has eaten ³/₆ = ½ of a pizza.
They each have ½ of a pizza left over.
The fractions here are ⁶/₁₂ and ³/₆.
Answer:
Yolanda will have a balance of $34,043.10 in 14 years.
Step-by-step explanation:
This is an Ordinary annuity question where you pick the hint from the equal and recurring monthly payment.
To find the Future value of Yolanda's savings after 14 years, use Future value of annuity formula FVA = ![\frac{PMT}{r}[1-(1+r)^{-t} ]\\](https://tex.z-dn.net/?f=%5Cfrac%7BPMT%7D%7Br%7D%5B1-%281%2Br%29%5E%7B-t%7D%20%5D%5C%5C)
PMT= recurring payment = $300
r = discount rate; monthly rate in this case = 6% / 12 =0.5% or 0.005 as a decimal.
t = total duration ; 14 *12 = 168 months
Next, plug in the numbers into the FVA formula;
FVA = ![\frac{300}{0.005} [ 1-(1+0.005)^{-168} ]](https://tex.z-dn.net/?f=%5Cfrac%7B300%7D%7B0.005%7D%20%5B%201-%281%2B0.005%29%5E%7B-168%7D%20%5D)
FVA = 60,000 * 0.5673849
FVA = 34,043.0969
Therefore, Yolanda will have a balance of $34,043.10 in 14 years
Answer:
4 batches
Step-by-step explanation:
4.8/1.2 = 4
Answer:
Step-by-step explanation:
If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b
x^2 + x - 12
Now factor this trinomial.
(x + 4)(x - 3)
Now put b back into the equation
(√b + 4)(√b - 3)
