Jasmine is traveling at 45 miles per hour. At that same rate, which of the following proportions could be used to find how long it will take her to travel 135 miles?
1. 45 miles / 1 hour = n hours/135 miles
2. 45 miles/n hours = 135 miles/1 hour
3. 45 miles /1 hour = n miles /135 hours
4. 45 miles/1 hour = 135 miles/n hours
Answers
Answer:
3 hours
Step-by-step explanation:
Jasmine's hourly distance covered (her rate of travel) is 45 mi / hr.
45 miles 135 miles
-------------- = ----------------
1 hour x
Cross-multiplying, we get 45x = 135, or x = 3 hours

Answers
Answer:
C
Step-by-step explanation:
If 30% of the entire population of students are seniors, then this will apply to the female population as well. This means that the probability of being a female senior is 30% * 54%=0.3*0.54=0.162=16.2%, or answer choice C. Hope this helps!
A ( 10cm height) and B ( 15cm height) are two similar solids the volume of A is 400cm^3 work out the volume of b
Answers
Answer:
1350 cm³
Step-by-step explanation:
Given 2 similar solids with sides in the ratio a : b , then
ratio of volumes = a³ : b³
Here the ratio of heights of A : B = 10 : 15 = 2 : 3 , thus
ratio of volumes A : B = 2³ : 3³ = 8 : 27
let x represent the volume of B then using proportion
[tex]\frac{8}{400}[/tex] = [tex]\frac{27}{x}[/tex] ( cross- multiply )
8x = 10800 ( divide both sides by 8 )
x = 1350
The volume of solid B = 1350 cm³

y = -3x + 60
Step-by-step explanation:
For the answer to the question above,
let x = number of weeks let y = amount of waste.
The linear equation may be expressed as,y = mx + b
m and b are the slope and y - intercept, respectively. Substituting the corresponding values,
(Week 5) 45 = 5m + b
(Week 10) 30 = 10m + b
Solving for m and b gives the values as m = -3 and b = 60. Thus, the equation is
y = -3x + 60

A car was marked $25,000. Ms. Eve bought it at a discount of
18%. In addition, she had to pay 7% tax. If Ms. Eve had to put
14% of what she had to pay as down payment, how much
money did she have to pay for the down payment?
4
Answers
Answer:
$3,745
Step-by-step explanation:
First, you have to calculate the price after the discount is applied:
Price of the car: $25,000
Discount: 18%
$25,000*18%= $4,500
$25,000-$4,500= $20,500
Second, you have to calculate the total amount she has to pay including the 7% tax:
$25,000*7%= $1,750
$25,000+$1,750= $26,750
Third, as the statement indicates that Ms. Eve had to put 14% of what she had to pay as down payment, you have to calculate the 14% of $26,750:
$26,750*14%= $3,745
According to this, Ms. Eve has to pay $3,745 for the down payment.

the weights of cars passing over a bridge have a mean of 3550 lb and a standard deviation of 870 pounds. Assume that the weights of cars passing over the bridge or never distributed. Use the empirical rule to estimate the probability that a randomly-selected car going over the bridge will weigh less than 940 lbs
Answers
Answer:
a. 0.15%
Step-by-step explanation:
The Z-score of 940 pounds is ...
(X -µ)/σ = (940 -3550)/870 = -3
The empirical rule tells you that 99.7% of the normal distribution lies within Z = ±3. Half of the remaining 0.3% lies below Z = -3, which is the set of weights of interest.
The probability that a car weighs less than 940 lbs is about 0.15%.

Answers
Answer:
Series "A" has an r value of "2/5" where 0 < |r| < 1 . So, we can find the sum of the series. The sum of the series is "50/3".
Step-by-step explanation:
To find the r (rate) of each series, we can divide one term by the term before:
Series A: 4 / 10 = 2/5
Series B: (3/5) / (1/5) = 3
So the series A has an r value between 0 and 1, so we can find the sum of the series.
The sum is given by the formula:
Sum = a1 / (1 - r)
Where a1 is the first term. So we have that:
Sum = 10 / (1 - (2/5))
Sum = 10 / (3/5)
Sum = 10 * (5/3) = 50/3
Answer:
Series "A" has an r value of "2/5" where 0 < |r| < 1 . So, we can find the sum of the series. The sum of the series is "50/3".
