Answer:
In mathematics, a cube root of a number x is a number y such that y³ = x. All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x: {\displaystyle r^{n}=x, } where n is a positive integer, sometimes called the degree of the root. A root of degree 2 is called a square root and a root of degree 3, a cube root.

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked

Evaluate the function rule for the given value. f(x) = 3^x for x = –5
A. 1/243
B. –15
C. 1/729
D. –125
Answer:
A. 1/243
Step-by-step explanation:
f(x) = 3^x
Let x = -5
f(-5) = 3^-5
We know a^-b = 1/a^b
f(-5) = 1/3^5
= 1/243

7+ 3 . (4)^2
7+3 . 16
10 . 16

Part: A Explain, using the complete sentences, what Jillian’s error was
Part B: show how the expression should have bee simplified using a similar format.
Please help me how should I explain it
Answer:
Part A: Jillian added 7+3 first rather than multiplying 3*16 b/c multiplication comes before addition
Part B:
7 + 3 * (10 - 6) ^2
7+ 3 * (4)^2
7+3 * 16
7 + 48

Step-by-step explanation:
Answer:
Part A:
Jillian's error was that they added the 7 and the 3 to get 10 and then multiplied by 16. Jillian should have multiplied the 3 and the 16 first and then added 7. This is because multiplication comes before addition in PEMDAS.
Part B:

i have been struggling for this work that has been assigned to me at the first day of school after a long time.
Answer:
Fill the gaps in this sequence:
25 36 49 64 81 100
This sequence is the numbers 5, 6, 7, 8, 9, and 10 squared.
Work out the cube root of 343, then square it.
49
Since 7 cubed equals 343, then 7 squared is 49.
When you subtract one square number from another the answer is 7.
What are the two square numbers?
16 and 9
These are the only squares that fit the criteria.
Write down a number you can square to give an answer bigger than 200 but smaller than 300.
15, 16, 17
All of those answers work. 15² is 225, 16² is 256, and 17² is 289. You can choose any of them to enter in and it should work.

Use the Pythagorean theorem to solve for the diagonal distance
Diagonal = sqrt(50^2 + 150^2)
Diagonal distance = sqrt(25,000)
Diagonal distance = 158.11 feet
Round to 158 feet.
If the stayed on the sidewalk they would walk 50 + 150 = 200 feet.
The distance they saved = 200-158 = 42 feet
Answer: 42 feet.

A. 0.07
B. 0.4
C. 0.6
D. 0.55
A. 0.07
Explaination:
if you were to say these are money.
0.59 would be 59 cents. 0.07 would be 7 cents.
59 is greater then 7 cents. so A is your answer
Answer:
0.07,0.4,.55 are all less than.59
Step-by-step explanation:
0.6 stands for 0.60 so it is the only one that is more than .59.
the hcf of 90 and x is 18. the lcm of 90 and x is 540. find the value of x.
The value of x is 108.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the HCF of 90 and x is 18.
And the LCM of 90 and x is 540.
We have to determine the value of x.
Since the product of two numbers equals the product of their HCF and LCM.
So 90 × x= HCF × LCM
Substitute the values of given data,
⇒ 90×x = 18×540
⇒ 90×x = 9720
⇒ x = 9720/90
⇒ x = 108
Hence, the value of x is 108.

Solve the system using the elimination method.
2x + 2y + 5z =−1
2x − y + z =2
2x + 4y − 3z =14
What x,y, and z?
Answer:
x=151/64 y=9/8 z=-51/32
Step-by-step explanation:
2x+2y+5z- (2x-y+z)=-1-2
3y+4z=-3
2x+2y+5z- (2x+4y-3z)=-1-14
-2y+8z=-15
We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)
3y+4z=-3 (2)
-2y+8z=-15 (-3)
6y+8z=-6
6y-24z=45
(6y+8z)- (6y-24z)= -6-45
32z=-51
z=-51/32
3y-204/32=-3
3y= -96/32+204/32
3y=108/32
y=36/32=9/8
2x+2*9/8+5*(-51/32)=-1
2x+9/4-255/32=-1
2x+72/32-255/32=-1
2x-183/32=-32/32
2x=151/32

Which expression can be used to convert 488 miles to yards
Answer:
488 Miles (mi)
=
858879.99997 Yards (yd)
Step-by-step explanation:
mile is a most popular measurement unit of length, equal to most commonly 5,280 feet (1,760 yards, or about 1,609 meters). The mile of 5,280 feet is called land mile or the statute mile to distinguish it from the nautical mile (1,852 meters, about 6,076.1 feet). Use of the mile as a unit of measurement is now largely confined to the United Kingdom, the United States, and Canada.
Yards : A yard (symbol: yd) is a basic unit of length
We have that The expression for converting 488 miles to yards will be
488miles*1760yard
From the question we are told that
Convert 488 miles to yards
Generally the expression for the conversion is is mathematically given as
Where
1mile=1760yards
Therefore
The expression for converting 488 miles to yards will be
488miles*1760yard
