on a day in winnipeg with 10 1/2 h of daylight, it was sunny for 1/3 of that time. for how many hours was it sunny that day
Considering the multiplication of mixed fractions, [tex]\frac{21}{6}[/tex] or 3.5 hours was sunny that day.
Multiplication of mixed fractionsTo multiply mixed fractions, it is necessary to transform these fractions into improper fractions. To do this, the whole part is multiplied by the denominator of the fraction that accompanies it. The result of the multiplication is added to the numerator of the fraction that accompanies it, and it will be the denominator of the new fraction, while the denominator remains the same.
After transforming the mixed fractions to be multiplied into improper fractions, they are multiplied. To do this, it is necessary to multiply the numerators of the two fractions, and the denominators of the fractions. If the resulting product needs to be simplified to lowest terms, divide the numerator and denominator by common factors.
Sunny hoursOn a day in winnipeg with 10[tex]\frac{1}{2}[/tex] h of daylight, it was sunny for [tex]\frac{1}{3}[/tex] of that time. This is:
10[tex]\frac{1}{2}[/tex] h × [tex]\frac{1}{3}[/tex]
Solving:
10[tex]\frac{1}{2}[/tex] h × [tex]\frac{1}{3}[/tex] = [tex]\frac{10x2+1}{2}[/tex] × [tex]\frac{1}{3}[/tex] = [tex]\frac{21}{2}[/tex] × [tex]\frac{1}{3}[/tex] = [tex]\frac{21x1}{2x3}[/tex]= [tex]\frac{21}{6}[/tex]= 3.5
Finally, [tex]\frac{21}{6}[/tex] or 3.5 hours was sunny that day.

A student chose a number, multiplied it by 2, then subtracted 138 from the result and got 102. What was the number he chose?
Answer:
51
Step-by-step explanation:
let's set the starting number as x
1. x times 2 = 2x
2. 2x- 138
3. result = 102
So, 2x-138 = 102
Now lets work backwards to solve for x.
1. 2x = 102
x = 51
So the starting number was 51.
If a person is chosen at random in this survey, what is the P(decaf or sugar)?
HELP PLS!
The value of the probability P(decaf or sugar) is 0.41
How to determine the probability?From the table, we have:
P(decaf) = 0.05 + 0.08 + 0.09 = 0.22
P(sugar) = 0.19 + 0.08 = 0.27
P(decaf and sugar) = 0.08
The required probability is:
P = P(decaf) + P(sugar) - P(decaf and sugar)
This gives
P = 0.22 + 0.27 - 0.08
Evaluate
P = 0.41
Hence, the value of the probability P(decaf or sugar) is 0.41

please explain how you got the answer!
The function represents the weekly weed growth f(x) = 86(1.01)^7x; They grow at approximately the rate of 1% per day.
What is a function?The function is a type of relation, or rule, that maps one input to specific single output.
The following function represents the weekly weed growth:
f(x) = 86(1.08)x.
we'll represent the growth function by day g(x). If x is to represent days, then x/7 represents weeks.
We can write,
g(x) = f(x/7) = 86·1.08^(x/7)
g(x) = 86·(1.08^(1/7))^x
g(x) = 86·1.011055^x

Use slopes and y-intercepts to determine if the lines 10x+3y=−3 and 5x−4y=−3 are parallel.
Answer:
They are not parallel
Step-by-step explanation:
original equation
10x + 3y = -3
subtract 10x
3y = -10x - 3
divide by 3
y = -10/3x - 1
original equation
5x - 4y = -3
subtract 5x
-4y = -5x-3
divide by -4
y = 5/4x + 3/4
the slopes are not equal to each other (5/4x and -10/3x) so they are not parallel
