A car travels a distance of 50km in 30mins. what is the average speed?
Answer:
r = 100 km/hr is the average speed of the car.
Step-by-step explanation:
The formula which relates distance d, time t, and speed or rate of travel r is:
d = rt.
We're given that the distance traveled d = 50 km and the time t traveled = 30 minutes = 1/2 hr. Substituting this given information into the distance-rate-time formula for d and t to find r, we get:
50 km = r(1/2 hr)
Now, dividing both sides by 1/2 hr, we have:
50 km/(1/2 hr) = [r(1/2 hr)]/(1/2 hr)
50 km/(1/2 hr) = r[(1/2 hr)/(1/2 hr)]
[50 km/(1/2)] km/hr = r[(1/2 hr)/(1/2 hr)]
50(2/1) km/hr = r[1]
100 km/hr = r[1]
r = 100 km/hr is the average speed of the car.
Mr Baxter deposits 2,000 in an account that earns %5 simple interest how much is mr Baxter investment after 8 years?
Answer:
$2,800
Step-by-step explanation:
The formula for simple interest is I = PRT, where I is the interest (earned or paid), P is the principal amount invested/borrowed, R is the rate in decimal form, and T is the time in years.
I = (2000)(0.05)(8)
I = $800
Then we add that to the principal to get $2,800
---------------------------------
Joey made a deposit into an account that earns 6% simple interest. After 3 years, Joey earned $400. How much was Joey's initial deposit?
I = PRT
400 = P(0.06)(3)
400 = 0.18P
P = $2,222. 22

Peter is calculating the interest earned on a deposit of $275 in an account that earns 8% simple interest after 12 years. What is the ??? guessing interest earned?

Judy built a rectangular patio that is 9 units wide and has a perimeter of 40 units.
Which image correctly labels the given information?
Answer:
See attachment for image
Step-by-step explanation:
Given
[tex]Width = 9[/tex]
[tex]Perimeter = 40[/tex]
Required
The image that illustrates the patio
The question is incomplete as the possible images are not given. So, I will attach an image that illustrates the scenario.
But first, the length of the patio must be calculated using perimeter formula
[tex]Perimeter = 2 *(Length + Width)[/tex]
[tex]40 = 2 *(Length + 9)[/tex]
Divide both sides by 2
[tex]20 = Length + 9[/tex]
Solve for Length
[tex]Length = 20 - 9[/tex]
[tex]Length = 11[/tex]
This implies that the dimension of the patio is 11 units by 9 units (See attachment)

Ty tried to evaluate an expression step by step.
8x2x3
Step 1: =8x(2x3)
Step 2: =8x6
Step 3: =42
Find Ty's mistake.
Choose 1 answer:
(Choice A)
Step 1
(Choice B)
Step 2
(Choice C)
Step 3
(Choice D)
Ty did not make a mistake.
Answer: C. Step 3
Step-by-step explanation:
Since we are informed that Ty tried to evaluate the expression step by step. The expression given is:
8x2x3
Step 1: =8x(2x3)
Step 2: =8x6
Step 3: =42
From the above, we can see that both step 1 and step 2 are correct but step 3 is wrong because 8 × 6 isn't equal to 42 but rather 48.
8 × 6 = 48 and not 42.
Therefore Ty's mistake is step 3.

A new phone system was installed last year to help reduce the expense of personal calls that were being made by employees. Before the new system was installed, the amount being spent on personal calls follows a normal distribution with an average of per month and a standard deviation of $50 per month. Refer to such expenses as PCE's (personal call expenses). Find the point in the distribution below which 2.5% of the PCE's fell.
Answer:
The point is [tex]\mu - 98[/tex], in which [tex]\mu[/tex] is the average per month.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normal distribution with an average of per month and a standard deviation of $50 per month.
Average of [tex]\mu[/tex], standard deviation [tex]\sigma = 50[/tex]
Find the point in the distribution below which 2.5% of the PCE's fell.
This is below the 2.5th percentile, which is the X when Z has a pvalue of 0.025, so X when Z = -1.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.96 = \frac{X - \mu}{50}[/tex]
[tex]X - \mu = -1.96*50[/tex]
[tex]X = \mu - 98[/tex]
The point is [tex]\mu - 98[/tex], in which [tex]\mu[/tex] is the average per month.

Answer:
m(arc FE) = 166°
Step-by-step explanation:
By theorem of intersecting chords and tangent of a circle,
Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.
m(∠GFE) = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]
83° = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]
m(arc FE) = 166°

Mike gets an 8% commission on the sporting goods that he sells.one day he sold sporting goods worth 1,384 find his commission for that day
Given:
Mike gets an 8% commission on the sporting goods that he sells.
One day he sold sporting goods worth 1,384.
To find:
The commission for that day.
Solution:
According to the given information,
Commission = 8% of total sales of sporting goods
One day he sold sporting goods worth 1,384. Then, the commission for that day is
[tex]\text{Commission}=\dfrac{8}{100}\times 1384[/tex]
[tex]\text{Commission}=\dfrac{11072}{100}[/tex]
[tex]\text{Commission}=110.72[/tex]
Therefore, the commission for that day is 110.72.
Use the figure below and 2-3 sentences to explain the following:
The side opposite angle E is side ____?
The side adjacent to angle E is side ____?
The hypotenuse is side ____?
Answer/Step-by-step explanation:
The triangle given is a right triangle
Reference angle = angle E
Thus:
The side that is opposite to angle E is side DF = e
The side that is adjacent to angle E is side EF = d
The hypotenuse side is the longest side that is opposite go the right angle of the triangle = DE = f

Caviar is an expensive delicacy, so companies that package it pay very close attention to the amount of product in their tins. Suppose a company that produces over 1,000 tins of caviar per day took an SRS of 20 tins from one day's production. The sample showed a mean of 99.8 g of caviar per tin with a standard deviation of 0.9g The amounts were roughly symmetric with no outliers. Based on this sample, which of the following is a 95% confidence interval for the mean amount of caviar (in grams) per tin from that day's production?
Answer: 99.8+-2.093(.9/V20)
