What’s - 46.15 as a mixed number
Answer: -46 15/100
Explanation: (see pic attached)
Answer:
46 3/20
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
46.15=46.15/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10^2 = 100
46.15/1 x 100/100= 4615/100
Find the Greatest Common Factor (GCF) of 4615 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5
4615/100 divided by 5/5= 923/20
Simplify the improper fraction
46 3/20
In conclusion
46.15= 46 3/20

You placed each of these cards in a brown paper bag and randomly select one and then record your results. After each selection, you place it back in the bag and select another. You do this for a total of 50 times and your results are: 6 times you picked the ace, 14 times you picked the 2, 13 times you picked the 3, 4 times you picked the 4, and 13 times you picked the 5. After looking at your results, what is the experimental probability of selecting the 4? Hint: You may have to reduce. *
Answer:
The experimenta probability of picking a 4 is [tex]\frac{4}{50}[/tex]
Step-by-step explanation:
To determine the experimental probability, we just need to divide the number of observations of the specific event by the total number of trials. In this case, we are interested in the event "picking a 4 card". This event happened 4 times. We have a total number of trials of 50. So , the experimental probability is
[tex]\frac{4}{50}[/tex]

Chen bikes 212 miles in 512 hour. What is Chen’s unit rate in miles per hour
Answer:
Unit rate = 0.414 mph
Step-by-step explanation:
Distance travelled = 212 miles
Time taken = 512 hours
[tex]Unit \: rate = \frac{distance \: travelled}{time \: taken} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{212}{512} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 0.414 \: mph (miles \: per \: hour)[/tex]
Answer:
53/128 mph
Step-by-step explanation:
Unit rate is essentially just asking for the number of miles Chen can bike in only 1 hour. That's what "unit" means - 1.
Here, we know that Chen can bike 212 miles in 512 hours, so let's set up a proportion:
[tex]\frac{212mi}{512hr} =\frac{x}{1hr}[/tex] , where x is the number of miles Chen can bike in 1 hour
Cross multiply:
512x = 212
Divide by 512:
x = 212 / 512 = 53/128 miles
So, Chen's unit rate is 53/128 mph.

Find the area of the Combined Rectangles.
Answer:
128
Step-by-step explanation:
First, I cut this rectangle in half vertically, right through the middle.
To find the area of an rectangle, multiply length by the height
Left rectangle area : 8*10 = 80 ( 8 is the height and 10 is the length)
Right rectangle area: 8*6 = 48 (8 is the length and 6 is the height)
Add the lengths together : 80+48= 128
The area of this rectangle is 128

Professor Trey Angle writes the equation y=10000(0.75)x on the chalkboard to introduce exponential decay to their students. They explain how when x = 0, y = 10000 and when x = 1, y = 7500. Finish his next statement: "As one gets larger, the other gets smaller. So If x = 3, then y = , which is under half the original value.
Answer:
"As one gets larger, the other gets smaller. So if x = 3, then y = 4218.8, which is under half the original value."
Step-by-step explanation:
In order to complete the sentence we must find the value of "y" when x = 3. We have:
y = 10000*(0.75)^3
y = 4218.8
The sentence then is:
"As one gets larger, the other gets smaller. So if x = 3, then y = 4218.8, which is under half the original value."

A trail mix consist of 7 3/4 oz of sunflower seeds, 9 1/4 oz of raisins, 4 1/4 oz of walnuts, and 7 1/2 oz of soybeans. If the mix is split equally between eight hikers, how much would each one get?
Answer:
Each biker gets 3 19/32 of the mix.
Step-by-step explanation:
In the questions, we are told that a trail mix consist
7 3/4 oz of sunflower seeds,
9 1/4 oz of raisins
4 1/4 oz of walnuts
7 1/2 oz of soybeans
Step 1
Add up every element in the trail mix
We have are given mixed numbers which is made up of whole number and a proper fraction
7 3/4 oz + 9 1/4 oz + 4 1/4 oz + 7 1/2 oz
So we add up the whole numbers first
27 + ( 3/4 oz + 1/4 oz + 1/4 oz + 1/2 oz)
Next, We find the lowest common multiple of the denominators of the proper fractions which is 4
= 27 + ((3×1) + (1×1) + (1×1) +(1×2)/4)
27 + (3+1+1+2) / 4
27 + 7/4
27 + 1 3/4
27 + 1 + 3/4
Total mix = 28 3/4
Step 2
If the mix is split equally between eight hikers, how much would each one get?
We would convert 28 3/4 into an improper fraction and divide it by 8 bikers
115/4 ÷ 8
115/ 4 × 1/8
= 115/32
Turning it into a mixed fraction, we have:
3 19/32
Therefore, each biker gets 3 19/32 of the mix.

start overline, A, B, end overline is a diameter of circle OOO.
What is the measure of \angle B∠Bangle, B?
^\circ
∘
degrees
Answer:Angle B is 44 Degrees
Step-by-step explanation: Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees
The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees
The angles of triangle ABC must add up to 180 degrees
m∠A+m∠B+m∠C=180
46+m∠B+90=180
m∠B+136=180
m∠B=44
The measure of Angle B in the given diagram is 44 Degrees
Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees
The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees
What is the sum of the angles in a triangle?The angles of triangle ABC must add up to 180 degrees.
The total sum of the angle in triangles is180 degrees.
m∠A+m∠B+m∠C=180
46+m∠B+90=180
m∠B+136=180
m∠B=44
Therefore, The measure of Angle B in the given diagram is 44 Degrees.

You put $2000 into an account earning 4% interest compounded continuously. Find the amount in the account at the end of 8 years.
Answer:
You'll need the attached formula.
Total = Principal * e ^ (rate * years)
rate = .04
Total = 2,000 * 2.718281828 ^ (.04 * 8)
Total = 2,000 * 2.718281828 ^ (.32)
Total = 2,000 * 1.3771277643
Total = 2754.2555285231
Total = 2,754.26 (rounded)
Step-by-step explanation:
The amount in the account at the end of 8 years will be $2,737.12.
To understand the calculations, check below.
