Answer:
The volume is 878.625
Step-by-step explanation:
First you can convert the mixed numbers and fractions into decimals to make life so much easier. 4 1/2 = 4.5 and 71/4 =17.75
Then simply mulitply 4.5 x 11 x 17.75 and get 878.625

Jennifer has a collection of 1,600 coins. Of the coins, 40% are dated before 1940, 35% are dated from 1940 to 1980, and the rest are dated after 1980. How many coins in Jennifer’s collection are dated after 1980?
Answer:
Step-by-step explanation:
40% + 35 % = 80 % so 20% are dated after 1980
20% is .20 in decimal form
.20 (1600) = 320 coins dated after 1980

Answer:
SA;
Area that will be covered with blue paint = 486 ft²
Step-by-step explanation:
✔️The four walls of Frank's room is to be covered with blue paint, therefore, it is a Surface area (SA) problem.
✔️Solve:
The number of square feet to be covered with blue paint = the surface area of the 4 faces
✔️Two of the faces have the following equal dimensions:
Length = 15 ft; height = 9ft
Surface area of the two faces = 2(15*9)
= 270 ft²
✔️The other two faces have the following equal dimensions:
Length = 12 ft, height = 9 ft
S.A = 2(12*9)
S.A = 216 ft²
Total area of the wall to be covered with blue paint = 270 + 216 = 486 ft²

The American College of Sports Medicine considers age as one factor when it recommends low and
high heart rates during workout sessions.
For safe and efficient exercise, your heart rate should be between 55% and 90% of the maximum
heart rate level. The maximum heart rate is calculated by subtracting a person's age from 220
beats per minute.
(Let a represent a person's age and h represent the person's recommended heart rate.)
1. The following equation represents the low value for heart rate. Simplify the equation.
h = .55(220-a)
2. The following equation represents the high value for heart rate. Simplify the equation.
h = .90(220-a)
3. Use these two expressions to write a system of inequalities that represents the heart rate range
for safe and efficient exercise. (Hint: you need to write two separate inequalities)
Answer:
.55(220-a) + .90(220-a)

Grace and her friends are playing a game that uses two dice. Each die is a tetrahedron –
a four‐sided shape with each side an equilateral triangle. Each side of the die contains
one of the digits 1, 2, 3, or 4.
a. Create the sample space of all possible outcomes if you were to roll the two dice
simultaneously. List the digit on the first die first and the digit on the second die
second (i.e. 1,1; 1,2; and so on.) (10 points)
b. What is the theoretical probability that the sum of the two numbers on a roll will
be five? (2 points)
c. If Grace and her friends were to roll the two dice 100 times, how many of the
100 times could they expect to roll the same number on each die? (In other
words, the outcome would be 1,1 or 2,2 or 3,3 or 4,4.) (4 points)
Answer:
Step-by-step explanation:
Very interesting problem. Be thankful it is not a six sided dice.

4 out of the 16 outcomes are possible
P(5) = 4/16 = 0.25
Part C
The theoretical out come would be 4 times
4/16 = 0.25
On a hundred rolls, you would expect to get 25 sets of doubles.

3 1 3 2 3 3 3 4 4 1 4 2 4 3 4 4
b.
4 possible outcomes!
c.
25 sets!
Step-by-step explanation:
a.
Try making a probability by using the counting principle method.
1 1 1 2 1 3 1 4 2 1 2 2 2 3 2 4
3 1 3 2 3 3 3 4 4 1 4 2 4 3 4 4
These numbers are the possible outcomes. Each 2 numbers stand for 1 outcome.
b.
16 possible outcomes
1 4 4 1 2 3 3 2
4/16 possible
P(5) = 4/16 = 0.25
c.
The theoretical outcome = 4 times
4/16 = 0.25
25 sets of rolls are expected to be rolled on the same number per 100 rolls.

What is the surface area of the jewelry box? And an explanation too, but if not, it’s alright!
Answer:
400
Step-by-step explanation:
The surface area is found when adding the areas of all the squares in the prism. 5x10=50, and we have that square twice, so 100. Again, 5x10=50, and we have that twice, so another 100. Then, 10x10, which is 100, and we have two of those, so 200. 100+100+200=400
Hope that helped, have a nice day!
Answer:
A. 400cm²
Step-by-step explanation:
The jewelry box is a rectangular prism.
Formula for surface area of a rectangular prism:
A = 2(w*l+h*l+h*w)
Plug in the numbers:
A = 2(10*10+5*10+5*10)
A = 400

What is equavalent 3 11/40.
The best estimate close to this answer 3 11/40
A. 2 1/2
B. 3 Plzz help me
C. 3 1/2
D. 4
Answer:
C. 3 1/2Step-by-step explanation:
Estimate the fraction part of the number.
11/40 > 10/40 = 1/4We can estimate the fraction part as 1/2 since its greater than 1/4.
The number becomes 3 1/2.
Best choice is C
Answer:
11/40>10/40=1/4 is a part of ½
so
best estimate is 3 ½.

Answer:
The height of the building is: 86.61m
Step-by-step explanation:
Given
The question is illustrated with the attached image
Required
Find h
To solve for h, we apply tangent formula i.e.
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
This gives:
[tex]\tan(60) = \frac{h}{50}[/tex]
Make h the subject
[tex]h = 50 * \tan(60)[/tex]
[tex]\tan(60) = \sqrt 3[/tex]
So, we have:
[tex]h = 50 * \sqrt 3[/tex]
[tex]h = 50 * 1.7321[/tex]
[tex]h = 86.61m[/tex]

A normal work day for Carl is from 8:00 a.m. to 4:30 p.m. Carl wants to figure out the degree measure that the hour hand makes while he is at work. Carl believes that if he divides 360 by 12 and multiplies the result by 8.5 he will have the correct degrees the hour hand moves. Is Carl correct? If not, choose the appropriate explanation.
A
Yes, Carl is correct. The process he takes will give him the correct degrees the hour hand moves.
B
No, Carl is incorrect. He must take the number he ends up with and subtract it from 360.
C
No, Carl is incorrect. The hour hand will go around the clock 360 degrees.
D
No, Carl is incorrect. He must first multiply 360 by 12 and then divide by 8.5.

A study has been done to test the effect of rock music on auditory attention. Eighteen eighth-grade students are randomly divided into two groups of 9 students, and the same hearing test was given to these students. The first group of students listened to rock music for 25 minutes right before taking the test, and the other group of students took the test without listening to the music. Here are their scores.
Group with music: 78 85 87 93 97 80 94 88 86
Group without music: 64 66 77 84 63 72 85 79 80
Assume normal populations with equal variance and construct a 95% confidence interval for the mean difference.
Find the lower bound of the confidence interval (round off to the nearest integer).
Answer:
The Lower bound of the confidence interval to the nearest integer = 6
Step-by-step explanation:
Calculate the Lower bound of the confidence interval
First step : Calculate the mean and standard deviation for each groups
Group 1 ( group with music )
N = 9
Total ( ∑x ) = 788
mean = 788 / 9 = 87.55
Variance ( s^2 ) = 39.777
s = [tex]\sqrt{39.77}[/tex] = 6.31
Group 2 ( group without music )
N = 9
∑x = 670
mean = 670 / 9 = 74.44
variance ( s^2 ) = 72.27
s = [tex]\sqrt{72.27}[/tex] = 8.50
Next : Calculate the pooled variance , standard error and confidence interval
Pooled variance ( Sp^2 ) : 896.43 / 16 = 56.03
standard error : S ( M1 - M2 ) = √((56.03 / 9) + (56.03 / 9)) = 3.53
confidence interval : μ1 - μ2 = ( M1 - M2 ) ± Ts ( M1 - M2 )
= 13.1111 ± (2.12 * 3.53 )
= ( 5.630 , 20.591 )
The Lower bound of the confidence interval to the nearest integer = 6

Five friends built a marble tower. The marble tower had a curved track. The track was designed so that the marbles would move down the track in a circular path. The track ended on the floor. Each friend predicted how he or she thought the marble would move when it rolled off the end of the track onto the floor. This is what they said:
Answer:
The best answer is of Keira's.
Step-by-step explanation:
The full question is as follows :
Given - Each friend predicted how he or she thought the marble would move when it rolled off the end of the track onto the floor.
This is what they said:
Magda : '' I think it will roll in circles.''
Soledad : '' I think it will curve for a bit and then straighten out.''
Allen : '' I think it will roll out in one big curve.''
Keira : '' I think it will roll in a straight line,''
Rafael : '' I think it will zigzag for a little while.''
To find - Which friend do you most agree with ?
Proof -
The best answer is Keira's.
The marble having the track will travel in a straight line.
The behavior is true for all objects.
If no outside force act on an object, the object will travel in a straight line at a constant speed.
When the marble leaves the end of the track, it is no longer in contact with the walls of the track.
That is , the marble has no longer a center-pushing force.
According to Newton's First law, an object remains at rest or in uniform motion in a straight line unless acted upon by an external force.
Since, there is no longer a center-pushing force so the marble rolls off the end of the track in a straight line path across the floor.
