Three rock samples have masses of 74.05 grams, 9.72 grams, and 45.49 grams. A scientist estimates the tatal mass of the samples by rounding each mass to the nearest whole number. Which lists the number will he add?
A. 75,10, and 46
B. 74.1, 9.7, and 45.5
C. 74, 10, and 45
D. 75, 10, and 50
The lists he would add would be C because 74.05 rounds to 74, 9.72 rounds to 10 and 45.49 rounds to 45 because it is closer to 45 than 46.
The Answer Is C) because 74.05 rounds to 74, 9.72 rounds to 10 and 45.49 rounds to 45 because it is closer to 45 than 46.

I know that: the first term of the sequence is -2, and the fifth term is -1/8
.
What do you know?
Solution
Here the first term = -2
5th term = -1/8
Now we have to find the common ratio (r)
Fifth term A5 = -1/8
-1/8 = [tex]a_{1} r^{4}[/tex]
Here [tex]a_{1} = -2[/tex]
Plug in [tex]a_{1} = -2[/tex] in the fifth term and find the value of r.
-1/8 = -2[tex]r^{4}[/tex]
r^4 = 1/16
Taking 4th root, we get
r = 1/2
Now let's find the second term.
first term *r = -2 *1/2 = -1
2nd term = first term * 1/2 = -1
3rd term = second term * 1/2 = -1 * 1/2 = -1/2
4th term = 3rd term *r = -1/2 *1/2 = -1/4
Thank you :)
For which of the following statements is the inverse false?
ANSWER
The correct answer is D
EXPLANATION
The conditional is
"If an angle's measure is [tex]35\degree[/tex], then it is an acute angle"
The above statement is true because both the premise and the conclusion are true.
Now let us consider the inverse of the above statement.
"If an angle's measure is not[tex]35\degree[/tex], then it is not an acute angle"
The above statement is false.
For example [tex]60\degree[/tex] is an acute angle even though its measure is not [tex]35\degree[/tex]
Handsome Jack is buying a pony made of diamonds. The price of the pony is PPP dollars, and Jack also has to pay a 25\%25%25, percent diamond pony tax.
Which of the following expressions could represent how much Jack pays in total for the pony?
Choose 2 answers:
A: P+1/4
B: P + 0.25 P
C: (P + 1/4) P
D : 5/4 P
E: 0.25P
Answer:
B: P + 0.25 P
D : 5/4 P
Step-by-step explanation:
The price is P.
The tax is 25% of P, or 0.25P.
The total price is the price plus the tax,
P + 0.25P = P + 1/4P = 4/4P + 1/4P = 5/4P
A percentage is a number expressed fraction of hundred
The correct options for the expression that represent how much Jack pays in total are;
B: P + 0.25·P
D: (5/4)·P
Reason:
The given parameters are;
Material from which the pony is made = Diamond
Price of the pony = P dollars
Amount Jack has to pay as diamond pony tax = 25%
Required:
The expression that represents how much Jack pays per pony
Solution:
The amount Jack pays, A = The price of the pony + Tax
The amount paid as tax = 25% of P = 0.25·P
∴ A = P + 0.25·P
The total amount Jack pays in total for the pony, A = P + 0.25·P[tex]\therefore A = P + 0.25 \cdot P = P + \dfrac{1}{4} \cdot P = \dfrac{5}{4} \cdot P[/tex]
Therefore; The total amount paid = P + 0.25·P = (5/4)·PThe correct options are; B: P + 0.25·P, and D: (5/4)·P

How much of an alloy with 30% copper must be added to 25 pounds of a second alloy that is 20% copper to create a 27% alloy? 33.85 lb 58.33 lb 391.67 lb
Answer:
58.33 lbs.
Step-by-step explanation:
There are already 25 lbs of alloy of copper
Of this 25 lbs, 20% is pure i.e. copper content = 25(0.5) = 5lbs.
Now available is
Copper Other metals
5 lbs 20 lbs
Let x lb of 30% copper is added.
Then new alloy will have 5+0.3x lb copper in total of 25+x lbs
Percentage pure = [tex]\frac{5+0.3x}{25+x} =27%[/tex]
Simplify to get
[tex]\frac{5+0.3x}{25+x} =\frac{27}{100} \\\\Cross multiply:\\27(25+x) =100(5+0.3x)\\500+30x =675 +27x\\3x = 175\\x = 175/3 = 58.33 lbs[/tex]
Hence answer is 58.33 lbs should be added.
The answer should be B or the second option. :)
which number is the additive inverse of-10 1/4
The additive inverse of the number is the same number but with the opposite sign.
The number you are given is negative, so the additive inverse would be positive.
The answer is 10 1/4
The additive inverse of -10 1/4 is 10 1/4, as it is the number that results in zero when added to the original.
The additive inverse of a number is the number that, when added to the original, will result in zero. For the number -10 1/4, its additive inverse would be the opposite sign of that number. Therefore, the additive inverse of -10 1/4 would be 10 1/4.
If x=12y, which expression represents 1x?
The correct answer is easy 1x=12y
simplify (12x-14)-(3x+9)-(-4-1)
(12x-14)-(3x+9)-(-4-1)
= 9x-18
12x-3x=9x
-14-9+4+1=-18
*Subtracting a group of numbers in parenthesis is the same as -1 times what every is in the parenthesis.
So it would be (12x-14)+(-3x-9)+(4+1)... which makes the equation alot easier to simplify.

Gabe drove 124 miles in 150 minutes. find Gabe's speed in kilometers per hour. HELP PLEASE FOR MY TEST TMMRW
First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words the kilometers per hour, which equals 49.6 km/h

write thw equation of the line that it is perpendicular to y=7x-3 and passes through the origin
Answer:
Equation of the line that it is perpendicular to y=7x-3 and passes through the origin is given by 7y + x = 0
Explanation:
We have equation of line , y =7x -3, comparing it with y = mx +c
So slope of line , m = 7
We know that the product of slopes of perpendicular lines = -1
So m*Slope of perpendicular line = -1
7* slope of perpendicular line = -1
slope of perpendicular line = -1/7
Given that the perpendicular line passes through origin (0,)0)
We also know that equation of a line passing though origin is given by the expression, y = mx
Here m = -1/7
So equation of perpendicular line, y = -x/7
or 7y + x = 0
Equation of the line that it is perpendicular to y=7x-3 and passes through the origin is given by 7y + x = 0
Complete the sentence. 0.05 is 1/10 the value of __?
To find the answer, multiply the decimal by 10. 0.05 X 10 = 0.5, and since 0.05 goes into 0.5 10 times, it is equivalent to 1/10th of 0.5.
0.05 is 1/10 the value of 0.5.
In this question, we are given that 0.05 is 1/10 the value of something, and we need to find out what that something is. To solve this, we can set up an equation:
0.05 = 1/10 * x
To isolate x, we can multiply both sides of the equation by 10:
0.05 * 10 = 1/10 * 10 * x
0.5 = x
Therefore, 0.05 is 1/10 the value of 0.5.

A "principal square root" is always...
A: a negative fraction
B: a positive integer
C: a negative integer
D:a positive fraction
Really none of the above.
A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.) It's not necessarily a positive integer, √2 being the obvious example.
Is √2 a positive fraction? We can write it as √2 / 1 so I suppose it is. It's certainly not a rational number. Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction. So "always" isn't correct.
I'd go with none of the above, but if I had to choose I'd choose D.

Out of 50 students, 11 are taking neither English nor Chemistry.
Explanation:To find the number of students taking neither English nor Chemistry, we need to subtract the number of students taking English, the number of students taking Chemistry, and the number of students taking both from the total number of students. So, the number of students taking neither is:
Total number of students - Number of students taking English - Number of students taking Chemistry + Number of students taking both = 50 - 15 - 30 + 6 = 11.
