Skye wants to buy 3 erasers each for her 4 best friends. If erasers cost $0.72 each, how much money does Skye need?
Answer:
3 x 4 = 12 erasers 12 x $0.72 = $8.64
Step-by-step explanation:
Answer: Skye will need $8.64
Step-by-step explanation:
We can start by seeing how many erasers she needs in total. We can multiply the 3 erasers for all 4 of her friends.
3 x 4 = 12 Erasers
Now we multiply the cost of one eraser by the total amount she needs, 12.
0.72 x 12 = 8.64
So the amount of money Skye needs for all her friends to have 3 erasers is $8.64
My neighbor has two cats and both cats have yellow eyes.
Therefore when two cats live together, they will both have yellow eyes.
The given conclusion uses inductive reasoning because it is based on which of the following?
A two observations
B using previously-proven theorems to show that two cats living together will have yellow eyes.
C showing that all cats with yellow eyes live together
D many observations
A: two observations.
The rest would prove for definite but due to the lack of observations (one case, two observation) this allows us to disprove (most likely) this conclusion.
write 7 83/100 as a decimal number
Answer: 7.83
Step-by-step explanation:
83 over 100 is the same as 83 divided by 100. 83/100 = 0.83
7 + 0.83 = 7.83
Answer:
7.83
Step-by-step explanation:
7 is the whole number
83 is the number that goes to the right of the decimal point
the 100(denominator) shows which place value it should be in, in the decimals place.

Answer:
D cos (1/2 x )
Step-by-step explanation:
y = cos (x/2)
because from the graph x = 2pie
= cos pie = -1
The function whose graph is given by; cos (1/2 x )
What is graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, the function must be having increasingly output for inputs greater than that value of x.
If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(π) = -1, thus
y = cos (x/2)
because from the graph x = 2π
The function whose graph is given by; cos (1/2 x )

The ratio for mixing mortar using sand, lime and cement is 3:2:1.
How many parts of each do you need to mix 42 parts in total?
sand
101
lime
cement
Answer:
Sand: 21 parts.
Lime : 14 parts.
Cement: 7 parts.
Step-by-step explanation:
The number of parts is 3 + 2 + 1 = 6.
So for 42 parts we need:
Sand: 3/6 * 42 = 1/2 * 42 = 21.
Lime: 2/6 * 42 = 1/3 * 42 = 14,
Cement: 1/6 * 42 = 7.

Answer:
To convert fahrenheit to celsius subtract 32 from the fahrenheit number and then multiply it by 5/9!!
1. a. about -17.78 degrees celsius
work: 0-32 = -32 times 5/9
-32*5 = -160
-160/9 = about -17.78
b. 0 degrees celsius
work: 32-32 = 0
0*5/9 = 0
c. about 21.11 degrees celsius
work: 70-32 = 38
38*5/9 = about 21.11
d. 37 degrees celsius
work: 98.6-32 = 66.6
66.6*5/9 = 37
e. about 37.78 degrees celsius
work: 100-32 = 68
68*5/9 = about 37.78
f. 100 degrees celsius
work: 212-32 = 180
180*5/9 = 100
celsius to fahrenheit is that number times 9/5, then + 32
2. (all of these answers are in degrees FAHRENheit. Make sure to write that!)
a. 32
work: 0*9/5 = 0 and 0+32 = 32
b. 89.6
work: 32*9/5 = 57.6.
57.6+32 = 89.6
c. 158
work: 70*9/5 = 126. 126+32 is 158
d. 209.48
work: 98.6*9/5 = 177.48. 177.48+ 32= 209.48
e. 212
work: 100*9/5 = 180. 180 + 32 = 212
f. 413.6
212*9/5 = 381.6. 381.6+32 = 413.6

Answer:
12. -11
13. 2
Step-by-step explanation:
12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction
For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.
From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.
Your new equation is -10-8+7 = -11
13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))
keep in mind there’s an addition between the twoDivision and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17
Second multiply 5 x -3 = -15
Now you can combine the two answers using addition: 17 + (-15) = 2
Divide (long division)
(4n^4+4n^3+16n^2)+4^2
9514 1404 393
Answer:
n^2 +n +4
Step-by-step explanation:
Since the divisor has only one term, the quotient is formed by dividing the terms one at a time.
[tex]\dfrac{4n^4+4n^3+16n^2}{4n^2}=\dfrac{4n^4}{4n^2}+\dfrac{4n^3}{4n^2}+\dfrac{16n^2}{4n^2}=\boxed{n^2 +n +4}[/tex]
__
Your long division tableau will subtract n^2×4n^2 = 4n^4 to form the new dividend 4n^3+16n^2. Then you will subtract n×4n^2 = 4n^3 to get the new dividend of 16n^2. The final quotient term is 4, and you will subtract 4×4n^2 to get a remainder of 0. You will have written the quotient as n^2+n+4.

6. Find the equation of the line perpendicular to y=2 through (1,5). * A. y 2 B.X D.X=2 耕
Answer:
Step-by-step explanation:
To convert the measurements of metric system into another units of metric system we have to either multiply it by 10, 100, 1000, 10000, 100000, etc or divide by 10, 100, 1000, 10000, 100000, etc.
If we have to convert bigger unit into smaller unit then we have to multiply the unit by the multiples of 10, then the decimal point is shifted to right by 1 or 2 or 3 or 4 , etc. places.
For example, 1.2 kg is converted into g so we have to multiply it by 1000, so decimal point is shifted to right by 3 places, i.e.,
1.2 x 1000 = 1200 g
If we have to convert smaller unit into bigger unit then we have to divide the unit by the multiples of 10, then the decimal point is shifted to left by 1 or 2 or 3 or 4 , etc. places.
For example, 12 cm is converted into m so we have to divide it by 100, so decimal point is shifted to left by 2 places, i.e.,
12 / 100 = 0.12 m
