GCF of 38 and 48

First find the prime factorization of 38 and 48.

38=2*19

48=2*2*2*2*3

The two number share the factor 2 and only 2. The GCF = 2.

Final answer:

The greatest common factor (GCF) of the number 38 is technically 38 itself. However, in the context of two or more numbers, it's the largest factor they share in common. For the single number 38, its factors are 1, 2, 19, and 38.

Explanation:

Finding the Greatest Common Factor (GCF) of 38

The greatest common factor of a number is the largest number that divides it, other than the number itself. Since 38 is a composite number and not a prime number, its factors are 1 and 38. The number 38 can also be divided evenly by 2 and 19, because 38 = 2 × 19. So, the factors of 38 are 1, 2, 19, and 38 itself. However, when we refer to the greatest common factor, it is usually in the context of finding the GCF between two or more numbers. For the single number 38, the GCF can be considered as the largest factor, which is 38 itself. But typically, the term 'greatest common factor' is more relevant when comparing it with another number to see the largest factor they have in common.

Answer:

y=-2x+7

Step-by-step explanation:

Memorize the formula y=mx+b where m=slope and b=y-intercept.

y=-2x+b passes through the point (1, 5)

5=-2(1)+b

5=-2+b

b=5-(-2)=5+2=7

So the y-intercept in this case is 7.

y=-2x+7

Answer:

[tex]x=\frac{1}{4}[/tex]

Step-by-step explanation:

We can use some logarithmic rules to solve this easily.

Note: Ln means [tex]Log_e[/tex]

Now, lets start with the equation:

[tex]ln(2x) + ln(2) = 0\\ln(2x) = -ln(2)[/tex]

Writing left side with logarithmic base e, we have:

[tex]Log_{e}(2x) = -ln(2)[/tex]

We can now use the property shown below to make this into exponential form:

[tex]Log_{a}b=x\\means\\a^x=b[/tex]

So, we write:

[tex]Log_{e}(2x) = -ln(2)\\e^{-ln(2)}=2x[/tex]

We recognize another property of exponentials:

[tex]a^{bc}=(a^{b})^{c}[/tex]

So, we write:

[tex]e^{-ln(2)}=2x\\(e^{ln(2)})^{-1}=2x[/tex]

Also, another property of natural logarithms is:

[tex]e^{(ln(a))}=a[/tex]

Now, we simplify:

[tex](e^{ln(2)})^{-1}=2x\\(2)^{-1}=2x\\\frac{1}{2}=2x\\x=\frac{\frac{1}{2}}{2}\\x=\frac{1}{4}[/tex]

This is the answer.

Answer:

1/5

Step-by-step explanation:

First, put the equation into slope-intercept form: y=mx+b, where m is the slope and b is the y-intercept.

5y=x+10, then divide both sides by 5;

y=1/5x+2

The slope is m, and m=1/5.

2. There was 5.33% error.

Step-by-step explanation:

1. Jerri estimated that 30 people would attend the dinner event, but only 25 people attended.

Exact value = 25

Approx value = 30

Percent error = [tex]\frac{|approx-exact|}{exact}*100[/tex]

Percent error = [tex]\frac{|30-25|}{25}*100 = \frac{|5|}{25}*100[/tex]

Percent error = [tex]\frac{500}{25} = 20\%[/tex]

There was 20% error.

2. Gene estimated the length of the fence to be 150 feet, but the actual measurement was 142.

Exact value = 142 feet

Approx value = 150 feet

Percent error = [tex]\frac{|150-142|}{150}*100 = \frac{|8|}{150}*100[/tex]

Percent error = [tex]\frac{800}{150} = 5.33\%[/tex]

28 to nine means it is 8:32 ( to get this you subtract 28 from 9.) ( its saying there are 28 minutes left until it is 9)

add 8 hours

= 8+ 8 = 16

well we arent talking about military time sooo 16-12 = 4

4 : 32 and you need to add the 59 so

32+ 59 = 91

91 - 60 = 31 (dont forget to add the extra 1 hour because we subtracted 60 minutes :). )

so the correct time will be 5: 31

Answer: 5:31

Step-by-step explanation:

28 minutes to 9 is 8:32

8 hours and 59 minutes later it would be 5:31

Check the picture below.

the idea being that sides of 2.5 andd 8 are fixed, what's are the possible lengths of "x"?

well, if we open the fixed sides, we'll end up with a 3rd side of 2.5 + 8 = 10.5, however if "x" is ever 10.5, the figure will become a flat-line and we'd be losing the triangle.

and if we close the fixed sizes, the longest "x" could be is 8 - 2.5 = 5.5, but the same, it can't be 5.5 exactly otherwise the figure will turn to a flat-line.

Answer:

We need to use the compound interest formula where the future amount is determined by

A = P(1 + r/n)nt

A = future or present amount = 5,000,000

P = initial amount invested = 8,000

r = interest rate as a decimal (to be determined)

n = # times compounded in a year = 1

t = # years = 200

5000000 = 8000(1+r/1)1(200)= 8000(1+r)200

(1+r)200 = 5,000,000/8,000

(1+r)200 = 625

1+r = 200√625

1 + r = 6251/200

r = 6251/200 - 1 = 0.0327

r ≅ 3.27%

Step-by-step explanation:

3.27% is interest rate compounded annually would this growth occur.

What exactly does "interest rate" mean?

The formula is -

A = P(1 + r/n)nt

given,

A = 5,000,000

P = 8,000

r = ?

n =  1

t =  200

put all the value in formula

5000000 = 8000(1+r/1)1(200)

5000000 = 8000(1+r)200

(1+r)200 = 5,000,000/8,000

(1+r)200 = 625

(1+r) = 200√625

(1 + r) = 6251/200

r = 6251/200 - 1

r = 0.0327

There are 8046.75 meters in 5 miles

Step-by-step explanation:

Method 1:

First of all we have to calculate the unit conversion.

Assuming that 3 miles is equal to 4828.05 meters

We have to find that how many meters make one mile

So,

3 miles = 4828.05 meters

[tex]1\ mile=\frac{4828.05}{3}\\=1609.35\ meters[/tex]

Now we know that:

[tex]1\ mile=1609.35\ meters\\5\ miles=1609.35*5 = 8046.74\ meters[/tex]

Method 2:

We can also use ratios to find the number of meters in 5 miles as:

3:4828.05::5:x

where x is the number of meters in 5 miles

[tex]\frac{3}{4828.05}=\frac{5}{x}\\x=\fac{5*4828.05}{3}\\=8046.75\ meters[/tex]

Hence,

There are 8046.75 meters in 5 miles

LENGTH OF AC IS 6

Step-by-step explanation:

Given :

the side AC = x ;

we need to find x;

since ∠A = ∠C , It's an isosceles triangle . i.e ,

the sides opposite to the angles ( AB and CB ) are also equal.

thus ,

side

AB = x+4 ;

CB = 3x-8 ;

thus AB = CB or ,

x+4 = 3x-8 ,

2x = 12 ,

x = 6 ;

therefore the side AC is 6.

Answer:

x = 64

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Sum the given angles and equate to 360

x + 2x + 114 + x - 10 = 360, that is

4x + 104 = 360 ( subtract 104 from both sides )

4x = 256 ( divide both sides by 4 )

x = 64

Without Table 14, a specific answer can't be provided. But generally you would find the y value when x is 3 for f(3), or find the x value when y is 1 for f(x)=1.

This question pertains to the evaluation of f(3) and solving for f(x)=1 within the given function f that's represented in Table 14. Unfortunately, as the Table 14 isn't provided, I can't give a specific answer. However, generally, to evaluate f(3), find the pair where the x value is 3; the corresponding y (or f(x)) value is the result of f(3). To solve f(x)=1, look for the pair in the table where the f(x) (or y) value is 1; the corresponding x value is the solution for f(x)=1.

Answer:600

Step-by-step explanation:

The 6 is in the hundreds place, so you in order to round it you would look at the 4. Since 4 is a a number less than 5 you round down. That would mean 600 instead of 700.

Answer: 600

Step-by-step explanation: To round 649 to the nearest hundred, we first find the digit in the rounding place which in this case is the 6 in the hundreds place.

To decide whether to round up or down, we look at the digit to the right of the 6 which is 4.

According to the rules of rounding, if the digit to the right of the rounding place is less than 5, we round down.

So in this problem, since 4 is less than 5, we round down.

This means that the 6 in the hundreds place stays the same and all digits to the right if 6 become 0.

So 649 rounded to the nearest hundred is 600.

The other leg is 12cm long.

Step-by-step explanation:

Given,

Hypotenuse = c = 15cm

One leg = a = 9cm

Other leg = b

As the triangle is right angled, therefore, using Pythagoras theorem;

[tex]a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\[/tex]

Taking square root on both sides;

Answer:

angle sum of a triangle’Formula

Step-by-step explanation:

N stands for the number of edges, - 2 is the result after finishing, 2 has no special significance. Because the sum of outer angles is a constant n-edge shape with 360 degrees, take n flat angles 180n = inner angle and + 360, so the sum of inner angles = 180n-360 = 180 (n-2)

That formula tells you what is the sum of the interior angles of a polygon with n sides.

So, for example, a triangle has n=3 sides, and in fact the sum of its interior angles is

[tex](3-2)\cdot 180=180[/tex]
