Step-by-step explanation:
5³ − (6/48) + 10²
= 125 - (0.125) + 100
= 224.875
or
5³ − (6/48) + 10²
= 125 - 1/8 + 100
= -1/8 + 225
= (225 * 8)/8 - 1/8

How do I solve this question? Rayne sold 3 desks at a local trade show. he payed $4.00 to rent the booth. he gave half of his revenue to the carpenter and was left with $185.50. at what price did Rayne sell each desk
Answer:
$125
Step-by-step explanation:
I suspect there's an error in the problem statement. Revenue is the money made from selling the desks. Profit is the revenue from the desks minus the cost of the booth rental.
If Rayne gives half of his profit to the carpenter, and x is the price per desk, then:
185.50 = ½ (3x − 4)
371 = 3x − 4
375 = 3x
x = 125

Answer/Step-by-step explanation:
Given:
[tex] 9w - 4w + 6 [/tex] < [tex] 1 + 5w [/tex]
To solve, collect like terms.
Subtract 5w from both sides
[tex] 9w - 4w + 6 - 5w [/tex] < [tex] 1 + 5w - 5w [/tex]
[tex] 9w - 4w - 5w + 6 [/tex] < [tex] 1 [/tex]

"Find an equation for the family of linear functions with slope 4. (Use the standard coordinate variables x and y. You may use m for the slope and b for the y-intercept as needed.)"
Answer:
Y= 4x +y1-4x1
4 represent the slope m
+Y1 - 4x1 represent the intercept b
Step-by-step explanation:
Formula for the equation of the linear function
(Y-y1)/(x-x1) = m
We will transform it into the equation form
Y= mx + b
Where m = slope=4
b = intercept
(Y-y1)/(x-x1) = m
(Y-y1)/(x-x1) = 4
(Y-y1)= 4(x-x1)
Y-y1= 4x -4x1
Y= 4x +y1-4x1
4 represent the slope m
+Y1 - 4x1 represent the intercept b
An equation for the family of linear functions with slope 4 is; y = 4x +b
Equation of a straight lineThe equation of a line can be determined by means of the slope as follows;
slope,m = (y-y1)/(x-x1)Therefore, for this scenario;
Slope,m = 4 = (y-y1)/(x-x1)By Cross-product, we have;
4x - 4x1 = y -y1Since, the y-intercept, b is the value of y for which x= 0.
Hence;
4x - 0 = y-by = 4x +bRead more on slope-intercept form;

If 5(x-4)+2= -173 what is the value of x?
Answer:
38.2
Step-by-step explanation:
5 (x-4) + 2 = 173
=> 5x - 20 + 2 = 173
=> 5x - 18 = 173
=> 5x - 18 + 18 = 173 + 18
=> 5x = 191
=> 5x/5 = 191/5
=> x = 38.2
So, x is 38.2
what is the gcf of 54, 72 and 108
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{18}}}}}[/tex]
Step-by-step explanation:
The GCF of any numbers can be obtained by using two methods. They are :
Prime factorization methodDivision methodNow, I am going to find out the GCF of 54 , 72 and 108 using these both methods :
Let's find out using the prime factorization method
First of all , find the prime factor of each numbers
54 = 2 × 3 × 3 × 3
72 = 2 × 2 × 2 × 3 × 3
108 = 2 × 2 × 3 × 3 × 3
Take out the common prime factors of given numbers
Common prime factors = 2 , 3 and 3
Multiply those common prime factors and the number obtained is G.C.F
GCF = Common prime factors
= 2 × 3 × 3
= 18
-----------------------------------------------------------
Now,let's find out using another method i.e division method
Steps for finding G.C.F by using division method:
Step 1 : Divide the larger number by smaller one.
Step 2 : In case of remaining remainder, divide the first division by that remainder.
Step 3 : Again if remainder leaves, divide the second divisor by the remainder.
Step 4 : Repeat the process until the remainder becomes the zero. So , that the last divisor is the G.C.F

A test consists of 20questions. Multiple choice questions earn 4points for a correct answer, and free response questions earn 8points for a correct answer. If the test is out of 100points, how many of each type of question are on the test?
Answer:
15 multiple choice questions
5 free response questions
Step-by-step explanation:
This is basically a systems of equations word problem.
To solve this, we need to create two equations that represent this scenario. Let's suppose [tex]m[/tex] represents the amount of multiple choice questions and [tex]f[/tex] represents the amount of free-choice questions.
We can create the following equations:
[tex]4m + 8f = 100[/tex]
[tex]m+f=20[/tex]
To solve for m and f, we can use elimination.
Let's multiply the equation [tex]m+f=20[/tex] by -4.
[tex]-4m - 4f = -80[/tex]
Great! Now let's add this equation to our first one, [tex]4m + 8f = 100[/tex].
[tex]4m + 8f = 100[/tex]
[tex]-4m - 4f = -80[/tex]
___________________
[tex]0m + 4f = 20[/tex]
[tex]4f=20[/tex]
Dividing both sides by 4 get us [tex]f=5[/tex].
So there are 5 free choice questions. To find m, we can substitute inside the equation [tex]m+f=20[/tex]
[tex]m+5=20\\\\m=20-5\\\\m=15[/tex]
So there are 15 multiple choice questions.

Elizabeth is selling jam at a farmers market, and she earns $5.00 for each jar of jam that she sells. Her goal for the weekend is to earn at least $450.00, and she has already made $95.00 from jam sales as well as $24.00 from leading a demonstration. What is the minimum number of jars Elizabeth must sell at this point to reach her goal?
Answer:
66 jars of jam
Step-by-step explanation:
Elizabeth is selling jam at a farmers market.
She earns $5 for each jar of Jan that she sells
Her goal is to earn $450 during the weekend.
Elizabeth has already made $95 from the sale of her jams and $24 from leading a demonstration
Therefore the total amount that has been made is
= $95 + $24
= $119
Since her target is $450 and she has already made $119 then the amount remaining to complete the target can be calculated as follows
= $450 - $119
= $331
The minimum number of jars that Elizabeth must sell to realize her goal can be calculated as follows
= 331/5
= 66
Hence Elizabeth must sell 66 jars of jam to reach her goal.

Answer:
Step-by-step explanation:
to compare them, we need to convert them into like fractions
4/3 and 5/2
lcm of 3 and 2 is 6
4/3 × 2/2 = 8/6
5/2 × 3/3 = 15/6
15/6 is greater than 8/6
so 5/2 is greater than 4/3
similarly,
-3/2 and -4/5
we need to convert them into like fractions
lcm of 2 and 5 is 10
-3/2 × 5/5 = -15/10
-4/5 × 2/2 = -8/10
-8/10 is greater than -15/10
so -4/5 is greater than -3/2

Because of the rainy season, the depth in a pond increases 3% each week. Before the rainy season started, the pond was 10 feet deep. What is the equation that best represents the depth of the pond each week? Hint: Use the formula y = P(1 + r)x. y = 10(0.03)x y = 10(0.3)x y = 10(1.3)x y = 10(1.03)x
Answer:
y = 10(1.03)^x
Step-by-step explanation:
In the formula y = p(1 + r)^x, p is the starting amount and r is the growth rate.
In this problem, the starting amount is 10. So, p = 10.
The growth rate is 3% each week, which is the same as 0.03 as a percentage. So, r = 0.03.
Plug these into the equation:
y = 10(1.03)^x will be the equation for this situation
The equation that best represents the depth of the pond each week is y = 10(1.03)× option (D) is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×
where a is a constant and a>1
We have:
A pond increases 3% each week.
The exponential growth is represented by:
y = p(1 + r)×
p = 10 feet
r = 3% = 0.03
y = 10(1 + 0.03)×
y = 10(1.03)×
Thus, the equation that best represents the depth of the pond each week is y = 10(1.03)× option (D) is correct.
