josh allowance is m cents per week. Represent the number of dollars he gets in a year.
a) 3m/25
b) 1200m
c) 13m/25
d) 25m/13
Answer:
The number of $ Josh receives in a year should be 13m / 25
Step-by-step explanation:
This is quite a simple a question.
Consider how many weeks there are in a year. Well there are about 52 weeks, you can say. Knowing that, you could apply the following conversion factor -
[tex]\frac{52 ( weeks ) }{ 1 ( year )}[/tex] ... at the same time we have to consider how many cents there are in a dollar. There are 100 cents, giving us the conversion factor [tex]\frac{1 ( dollar )}{100 ( cents )}[/tex]. Therefore, Josh's allowance should be, after 1 year -
m [tex]*[/tex] [tex]\frac{52}{1}[/tex] [tex]*[/tex] [tex]\frac{1}{100}[/tex]
= [tex]\frac{52m}{100}[/tex] - Which, simplified, = [tex]\frac{13m}{25}[/tex].
Our solution here is option c, rather option d.
The number of dollars he gets in a year is 13m/25 option (c) is correct if josh allowance is m cents per week.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We have:
Josh's allowance is m cents per week.
As we know,
Total number of weeks in a year = 52 weeks
In 1 dollar there are 100 cents
josh's allowance is m cents per week
The number of dollars he gets in a year = (52/100)m
After simplification:
The number of dollars he gets in a year = 13m/25
Thus, the number of dollars he gets in a year is 13m/25 option (c) is correct if josh allowance is m cents per week.

A). m + 2 = 1
B). m + 1 = 3
C). m + 1 = 2

Answer: C
Step-by-step explanation:
not A because m=1 so 1+2 doesn’t equal 1.
Not B because m=1 and 1+1=2 not 3.
Not D because m=1 and 1-2= a negativ.
C because m=1 and 1+1=2 like shown for C.

What is the probability that a number selected at random from set S above will also be in set T?
O 0.1
O 0.2
O 0.4
O 0.5
Answer:
0.2
Step-by-step explanation:
the total is 10
they said that it has to be the same group as S and T
the only numbers that are in the same groups is 2 and 4
the fraction is then 2/10
which is .2
correct me if i am wrong
The probability that a number selected at random from set S above will also be in set T will be 0.2 hence, option (B) will be correct.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
Do not take underestimate probability it has several uses in daily life whether forecasts and like that.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
Given that the S = {2, 4, 6, 8, 10 and T = {1, 2, 3, 4, 5)
Now there are a total of 10 numbers. The common number among S and T are 2 and 4 only so
Probability = 2/10 = 0.2 hence it will be correct.

Two cars are travelling from Toronto to Quebec. Car A left Toronto at 8 a.m. and is moving with an average speed of 70 km/h. Car B left Toronto at 10 a.m. and its average speed is 90 km/h. How many hours will it take for car B to catch car A?
(please show all your work Let, So, Equation and Solution and Therefore Statement)
Answer:
It'll take 7 hours for the car B to cath up to A
Step-by-step explanation:
In order to solve this problem we can write the equation from the distance of each car. Assuming that t = 0 happens when the second car leaves Toronto. When the second car leaves Toronto, the first one is on the road for two hours already, thefeore it travelled a total of:
distance = speed*time = 70*2 = 140
We have:
Car A:
x(t) = 70*t + 140
Car B:
x(t) = 90*t
We now need to find the value of "t" that makes x(t) the same for both cars:
90*t = 70*t + 140
20*t = 140
t = 140 / 20 = 7 h

Find the area of the trapezoid.
Answer:
A = 108 m^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases
A = 1/2(10+14) (9)
A = 1/2 (24)*9
A = 108 m^2
Answer:
108 meters squared
Step-by-step explanation:
Area = (1/2)(base 1 + base 2)*height
Area= (1/2)(14+10)*9
Area= (1/2)(24)(9)
Area= 12*9
Area= 108 meters squared

The quotient of the given function is [tex]\frac{\sqrt{3}}{2}[/tex]
Given the radical function
[tex]\dfrac{3\sqrt{8} }{4\sqrt{6} }[/tex]Rationalizing the denominator:
[tex]= \dfrac{3\sqrt{8} }{4\sqrt{6} } \times \dfrac{\sqrt{6} }{\sqrt{6} }\\= \dfrac{3\sqrt{8} (\sqrt{6}) }{4\sqrt{6} \cdot \sqrt{6}}\\[/tex]
Multiplying the numerator and denominator:
[tex]=\dfrac{3\sqrt {48}}{4(6)} \\=\dfrac{3(4\sqrt{3})}{24} \\=\dfrac{4\sqrt{3}}{8} \\=\dfrac{\sqrt{3}}{2}[/tex]
