Answer:the ages of the youngest and the eldest is 4 years and 20 Years respectively

Step-by-step explanation:

Ratio of the ages of three children is 2:5:1.

Total ratio =2+5+1=8

So that

the 1st Child's age =2/8 x 32=8  years

2nd  Child's age =5/8 x 32= 20 years

3rd Child's age =1/8 x 32= 4  years

Therefore the ages of the youngest and the eldest is 4 years and 20 Years respectively.​

Answer:

Step-by-step explanation:

Domain of a function defines the input values (x-values) of the function.

Given linear function is,

y = -2x - 5

Domain of the function is,

{-6, -5, -2, 0, 1}

By substituting the values of x in the equation we can get y-values (output values).

Input-output table for the function,

x            -6            -5            -2             0             1

y             7             5             -1             -5           -7

Now we can plot these points of the graph.        

Answer:

The function f(x) = 4.95x represents the cost to purchase x pounds of chocolate from a candy company. The function g(x) = 0.99x + 2.25 models the cost to ship x pounds of chocolate from the company.

8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.

Your answer would be 2.

Answer:

2 students cannot sit down at tables.

Step-by-step explanation:

Since there are a total of 58 students and only 7 tables and each table can only fit 8 students, you'll need to calculate how many students can sit at 7 tables first:

7(8) = 56 So, with 8 students sitting at all 7 tables, there are 56 students that can sit at a table.

To find how many students can't sit at a table you'll have to subtract 56 from 58,

58-56 = 2 So, 2 students will not be able to sit down at tables.

Answer:

B

Step-by-step explanation:

The interior angles of a triangle always add up to 180 degrees.

We have two angles already and they add up to 60+63=123 degrees

180-123=57

so the remaining angle is 57 degrees

9514 1404 393

Answer:

  D.  123°

Step-by-step explanation:

The external angle is equal to the sum of the remote internal angles.

  m∠1 = 60° +63°

  m∠1 = 123°

Answer:

the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis is;

[tex]\frac{\pi }{2} [e^2 - 1 ][/tex]  or 10.036

Step-by-step explanation:

Given the data in the question;

y = [tex]y = e^{(x - 1 )[/tex], y = 0, x = 1, x = 2.

Now, using the integration capabilities of a graphing utility

y = [tex]y = e_2}^{(x - 1 )_[/tex], y = 0

Volume = [tex]\pi \int\limits^2_1 ( e^{x-1)^2} - (0)^2 dx[/tex]

Volume = [tex]\pi \int\limits^2_1 ( e^{x-1)^2 dx[/tex]

Volume = [tex]\pi \int\limits^2_1 e^{2x-2}dx[/tex]

Volume = [tex]\frac{\pi }{e^2} \int\limits^2_1 e^{2x}dx[/tex]

Volume = [tex]\frac{\pi }{e^2} [\frac{e^{2x}}{2}]^2_1[/tex]

Volume = [tex]\frac{\pi }{2e^2} [e^4 - e^2 ][/tex]  

Volume = [tex]\frac{\pi }{2} [e^2 - 1 ][/tex]  or 10.036

Therefore, the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis is;

[tex]\frac{\pi }{2} [e^2 - 1 ][/tex]  or 10.036

Step-by-step explanation:

Carmen's father is 28 years older than her, 3 years ago we was 5 times her age, what are their ages?

The best centre of measure for this data is the mean which is equal to 10.90 seconds.

Mean, median and mode are use to measure for central tendency. Therefore, let's arrange the values in ascending order.

10.72, 10.75, 10.78, 10.80, 10.80, 10.88, 10.96, 10.99, 11.02, 11.10, 11.10,

According to the data, the values are very close to catch. Therefore, the mean will be used. Therefore,

mean = sum of data / number of data

mean = 10.72 + 10.75 + 10.78 + 10.80 + 10.80 + 10.88 + 10.96 + 10.99, 11.02 + 11.10 + 11.10  / 11

mean = 119.9 / 11

mean = 10.90

Answer:

384

Step-by-step explanation:

I just went to my calculator and did 24×16 and I got 384

Answer:

a: m=5/3

b: m=-3/5

Step-by-step explanation:

first, before answering the questions, let's change the line from standard form (ax+by=c), where a and b are free coefficients into slope-intercept form (y=mx+b), where m is the slope and b is the y intercept

subtract 5x from both sides

-3y=-5x+7

divide by -3

y=5/3x-7/3

now to answer part a:

parallel lines have the same slopes, but different y intercepts.

the slope of the given line is 5/3, so therefore, a parallel line to the line y=5/3x-7/3 will also be 5/3

part b:

perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1

so to find the slope of a perpendicular line, use this formula:

5/3m=-1

multiply by 3/5 to isolate the variable

m=-3/5

therefore the slope of a perpendicular line will be -3/5

hope this helps!

Answer:

m<1 = 125°

m<2 = 55°

Step-by-step explanation:

Okay, so we're dealing with alternate interior angles and all that sorta stuff, so I'll try to explain it best I can, if I'm too confusing let me know, let's go:

So the angle labeled 125° and angle 1 are alternate interior angles, so they're equal (yes, we're ignoring the fact that that might not me right because the other line isn't straight, I don't have another solution okay) anyways, so that means that:

1 = 125°

Now we know what 1 and 2 are on the same plane or axis or something like that, so basically, 1 and 2 HAVE TO add up to 180°, so that means that:

125 + x = 180

And now we just have to do the inverse operations thing:

180 - 125 = 55

So, m<1 = 125° and m<2 = 55°

tell me if this is wrong so I can fix it

Answer:

3.5944

Step-by-step explanation:

first the fraction is mixed and you need to change the fraction to proper or improper fraction

the denominator 4 is multiply 16

16×4=64

then the numerator 3 is add to 64

64+3=67

the fraction will be

=====67/4

the denominator is not change from the first part

》》do the same thing by the other mixed fraction

the final answer would be 3.5944

first calculate 67÷4=16.75

the second calculate 14÷3=4.66

in the second part i get 14/3 that means i change the mixed fraction to the normal fraction

calculate 16.75÷4.66=3.5944
