The base 10 log table shows that the value of log10^50 is about 1.69897. explain or show why it makes sence that the value is between 1 and 2
Answer:
Step-by-step explanation:
Given
[tex]\log _{10}\ 50=1.69897[/tex]
and we know that
[tex]\log _a\ a=1[/tex]
therefore
[tex]\Rightarrow \log _{10}\ 10=1[/tex]
and [tex]\Rightarrow \log _{10}\ 100=\log _{10}\ 10^2=2[/tex]
and [tex]50[/tex] lies between [tex]10[/tex] and [tex]100[/tex] . So, its value must lie between [tex]1[/tex] and [tex]2[/tex]

the sum of four consecutive integers is 34. find the least of the numbers
Answer:
7
Step-by-step
n=smallest integer; n+1=second integer; n+2=third integer; n+3=fourth integer
n+(n+1)+(n+2)+(n+3)=34
4n+6=34
4n=28
n=7 ANSWER: The smallest integer is 7
CHECK:
7+8+9+10=34
34=34
the least of the four consecutive integers is 7.
Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.
According to the given information, the sum of these four consecutive integers is 34:
x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34
Simplifying the equation:
4 x + 6 = 34
Subtracting 6 from both sides:
4 x = 28
Dividing both sides by 4:
x = 7
The four numbers are 7, 8, 9, 10
Therefore, the least of the four consecutive integers is 7.

Jakob was asked to write an equation and solve this problem. Max saved enough money to buy three tickets to a baseball game. If each ticket costs $18.75, how much money did Max save? Jakob’s work is shown below.
Answer:
$56.25
Step-by-step explanation:
We know that Max has just enough money to buy 3 tickets that each cost $18.75, so let's write the expression:
18.75 * 3
We just solve this by multiplication:
18.75 * 3 = $56.25
Max saved $56.25.
Answer:
$56.25
Step-by-step explanation:
His savings were equal to the cost of 3 tickets, therefore
Savings = 3 × 18.75
Savings = 56.25

Which expression finds the measure of an angle that is coterminal with a 126° angle?
Answer:
Therefore the expression that finds the coterminal angles is:
[tex]coterminal = 126\º \pm 360[/tex]
Step-by-step explanation:
Coterminal angles are angles that finish at the same line. Therefore in order to find the coterminal angles with 126º we need to add or subtract a angle of 360º. So the expressions are:
coterminal angle = 126º + 360º = 486º
coterminal angle = 126º - 360º = -234º
Therefore the expression that finds the coterminal angles is:
[tex]coterminal = 126\º \pm 360[/tex]
Answer:
126° + (720n)°, for any integer n or D on edge :)

Each interior angle of a regular polygon is 140°.Find the number of sides of the polygon.
Answer :
9 sides
Explanation:
Step 1
Since the interior angle is 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Step 2
Method 2: Since the exterior angle is 140°
The sum of the interior angles = (2n - 4) × right angles.
So 140n =(2n - 4) ×right angles, or we can also say
140n =(2n - 4) × 90
140n = 180n - 360
40n = 360
Divide both sides of the equation by 40
n = 9 sides.
n = 9 sides.Hence the number of sides is 9 sides.

The weight of an object on Moon is 1/6 its weight on Earth. Find the weight of the object on Moon which weighs 28/5 Kg on Earth.
Find 3/4 of 5/7
It'd really help me out if anyone answers this!!
Answer:
1) A profit of Rs 250 is made.
3) 11 marks
3) 14/15 kg
4) 15/28
Step-by-step explanation:
1) A profit of Rs.10 per bag of oranges and a loss of Rs.5 per bag of grapes sold. The total profit/loss from selling 200 bags of oranges and 350 bags of grapes is:
total profit/loss = 200 (10) - 5(350) = 2000 - 1750 = Rs 250
A profit of Rs 250 is made.
2) (+5) marks are given for every correct answer and (-3) marks are given for every incorrect answer and 0 for answer not attempted. If he answer 4 correct and 3 incorrect out of 7 questions. His score is:
Score = 5(4) - 3(3) = 20 - 9 = 11 marks
His score is 11 marks
3) An object weighs 28/5 kg on earth. Since its weight on moon is 1/6 its weight on Earth.
The weight on moon = 1/6 × 28/5 = 14/15 kg

f(x) = 4^x-1; find f(3)
Answer:
f(3) = 63
Step-by-step explanation:
f(x) = 4^x-1;
Let x =3
f(3) = 4^3 -1
= 64-1
=63
Answer:
f(3)=16
Step-by-step explanation:
This question asks us to find f(3). We have to find what f(x), or y is, when x is equal to 3.
f(x)=4^x-1
Substitute 3 in for x.
f(3)=4^3-1
First, subtract what is in the exponents.
f(3)=4^2
4^2 is the same as multiplying 4, 2 times.
4^2=4*4=16
f(3)=16
Find the value of c (x-2) is a factor of the polynomial p(x). P(x)=x^3-4x^2+3x+c
Answer:
c = 2
Step-by-step explanation:
P(x)=x^3-4x^2+3x+c
The polynomial has x - 2 as a factor
Rewriting the polynomial as:
x^3-4x^2+3x+c = x^3 - 2x^2 - 2x^2 + 4x - x + c =x^2(x - 2) - 2x(x - 2) - (x - c)As we see the first 2 terms have (x -2) as a factor, so the third term:
(x - c) = (x - 2) c=2Answer is c= 2

a light bulb manufacturer finds that 4% of the bulbs it makes are defective. The quality control officer predicts that 700 bulbs will be defective out of 15,500 bulbs made. Do you agree? Explain.
Answer:
No, 4% is 620 light bulbs
Step-by-step explanation:
No, because 700 out of 15,500 is 4.5% not 4 %. 4% of 15,500 would be 620 light bulbs

If 30% of the students taking a module failed the practical test. The class has 130 students. How many students passed the test?
Answer:
91 students passed the test.
Step-by-step explanation:
130 / 10 = 13
13 x 3 = 39
130 - 39 = 91
Answer:
91 students passed the test.
Step-by-step explanation:
We need to find 10% of 130.
130÷10=13
Then we need to make it 30% in order to see the amount of students that failed the test.
13×3=39
Then we need to do 130 - 39 (The whole class- 30%)
130-39=91

What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
Answer:
Step-by-step explanation:
if m is the slope of given line.
Then eq. of parallel line through (-4,-6) is
y+6=m(x+4)
Answer:
y=-6
Step-by-step explanation:
The line shown is a horizontal line through the y-axis and has the equation y=4. A parallel line to it is a line that does not cross it. It will also have the form y=a where a is the y-coordinate of its points. The point (-4,-6) is on the line so y=-6 is the line.
