hi, can someone please help me with this. will give brainliest.
Answer:
It will be a positive sign.
Step-by-step explanation:
Since the exponent is an odd number, the base is going to keep the same sign. Then, since you are dividing a negative number by a negative number, you will get a positive number.
I hope this helps!
A carpenter charges $45 for every 50 feet of fence he builds plus a travel charge of $37.50. If the equation, C = 4550F + 37.5 , can be used to determine the total cost, C, of building F feet of fence, how many feet of fence can be built for a cost of $352.50?
Answer:
Step-by-step explanation:
Given the total cost of the building expressed as;
C = 4550F + 37.5
C is the total cost
F is the length of the fence
Given
C = $352.50
Required
The length of the fence F
Substitute into the formula;
C = 4550F + 37.5
$352.50 = 4550F + 37.5
4550F = 352.50 - 36.5
4550F = 316
F = 316/4550
F = 0.0695 feet
hence 0.0695 feet of fence will cost $352.50

Katie has f fish. Alejandro has 11 fish, which is 3 fewer than twice the number Katie has.
Which equation shows an equality between two different ways of expressing how many fish Alejandro has?
A. f + 3 = 11
B. f – 3 = 11
C. f/2 - 3 = 11
D. 2f – 3 = 11
Answer:
The answer would be D
Step-by-step explanation:
To find how many Katie has, you would have to double it ( times by 2 ). Then subtract 3, since Alejandro has three less than twice as many as Katie.
Answer:
the answer is d just did the test got it right

Solve the system of linear equations using multiplication. - 3x + 2y 5x - 3y = 17 The solution is
Answer:
Required Answer:-
Given:
5x - 3y = 2
3x - 2y = 4
To Find:
The values of x and y.
Solution:
We have,
→ 5x - 3y = 2 – (i)
→ 3x - 2y = 4 – (ii)
Multiplying equation (i) by 2, we get,
→ 10x - 6y = 4 – (iii)
Multiplying equation (ii) by 3, we get,
→ 9x - 6y = 12 – (iv)
Subtracting (iii) from (iv), we get,
→ -x = 8
→ x = -8
Now, from (i),
→ 5 × (-8) - 3y = 2
→ -40 - 2 = 3y
→ -42 = 3y
→ y = -14
So,
→ (x, y) = (-8, -14)
Answer:
(x, y) = (-8, -14)

What represents 200 million
Answer:
200 million represents a very large number and therefore it is not commonly encountered in the history of the people of God. However, is reflected in the number of silver coins annually paid by the vinedressers who farmed King Solomon's vineyards (ie, 1,000 x 1,000 x 200).

What is an equation of the line that passes through the point (6, 1) and is
perpendicular to the line 2x + 3y = 18?
Answer: y=1,5x-8
Step-by-step explanation:
At first transform the equation
2x+3y=18
3y= 18-2x
y= 6 - (2/3)x
The linear function has general form, which looks like that:
y=mx+n
perpendicular means that m1*m2=-1
In our case m1= -(2/3) and m2 is unknown
(-2/3)*m2= -1
m2=3/2 so m2=1,5
The line has to go through the point (6,1)
so 1=6*1,5+n
1=9+n
n= -8
so the function looks like that y=1,5x-8
Point A is located at -4.5, and point B is 3.25 units from point A. Write two additional equations that could be used to determine the location of point B.
Answer:
The equations are B = -4.5 + 3.25 and B = -4.5 - 3.25
Step-by-step explanation:
Since point A is located at -4.5 and point B is 3.25 units away from A, point B can either be located on the left or on the right of point A.
If point B is located at the right of A, the equation for point B is -4.5 + 3.25.
If point B is located at the left of A, the equation for point B is -4.5 - 3.25.
So, the equations are B = -4.5 + 3.25 and B = -4.5 - 3.25
Kim creates a model of a building. The scale of her model building is 1 foot to 8 inch. Some of the measurements are shown in the table. 11 Enter numbers in the empty boxes to correctly complete the table.
Answer:
Left
50 feet
Right
16 inches
10 inches
Step-by-step explanation:
Here, we want to make a conversion and fill in the empty spaces
The scale is 1 foot is 1/8 inch
To convert from foot to inch, we multiply by 1/8
To convert from inch to foot, we multiply by 8
Thus, we have ;
Let’s fill in the left spaces first;
6.25 * 8 = 50 feet
Right spaces, top to bottom;
128 * 1/8 = 16 inches
80 * 1/8 = 10 inches
3) A product is marked down 15%; the sale price is $127.46. What was the
original price?
Answer:elling price (S.P) = (100 - m)% ⋅ Original price -----(1)
Here,
S.P = 127.46, m = 15
Substitute 127.46 for S.P and 15 for m in (1).
127.46 = (100 - 15)% ⋅ Original price
127.46 = 85% ⋅ Original price
127.46 = 0.85 ⋅ Original price
127.46 / 0.85 = Original price
149.95 = Original price
So, the original price is $ 149.95.
Step-by-step explanation:
The original price of product when the product is market down by 15% and the sales price is given so it is $149.95.
Calculation of price:Price is down by 15%, so m = 15% or 0.15.
So, Original price = [tex]\frac{Selling price}{( 1 - m)}[/tex]
By putting the value, we get
Original price = [tex]\frac{127.46}{(1 - 0.15)}[/tex]
= [tex]\frac{127.46}{0.85}[/tex]
= $149.95
Hence the original price of of the product was $149.95

Please help and look at the image. (The table shows the transportation method of employees at a certain company. What percent of the employees walk to work?
)
Answer:
0.5% to walk to work.
Step-by-step explanation:
First, find town many employees in total, Add all the numbers to find it. We get 1400, next we find the percentage of 1400 that gets us the number 7.
0.5% of 1400 is 7 so 0.5% is the answer :)
Michael record the number of miles he runs each week for the nine weeks 6,11,13,8,15,9,11,5,9 which box plot represents the data
Five number summary
min = 5Q1 = 7median = 9Q3 = 12max = 15===============================================
Explanation:
The given list of values is {6, 11, 13, 8, 15, 9, 11, 5, 9}
It sorts to {5, 6, 8, 9, 9, 11, 11, 13, 15}
The middle most value is the second 9. We have four items below or at the median {5,6,8,9} and four values above the median {11,11,13,15}
The middle item of {5,6,8,9} is (6+8)/2 = 14/2 = 7. This is the value of Q1.
The middle item of {11,11,13,15} is (11+13)/2 = 24/2 = 12. This is Q3.
The min is 5 since it is the smallest of the original list.
The max is 15 because it is the largest of the original list.
The five number summary is
min = 5Q1 = 7median = 9Q3 = 12max = 15The boxplot that matches with this five number summary is the boxplot in the upper right corner.
The min is the left whisker. The max is the right whisker.
The left edge of the box is Q1. The right edge of the box is Q3.
The middle vertical line inside the box is the median.
Answer:
upper right corner

Triangular numbers can be represented with equilateral triangles formed by dots the first fire triangle numbers are 1 3 6 10 and 15 is there a direct variation between a triangle number and its position in the sequence explain your reasoning
Answer:
There's no direct variation
Step-by-step explanation:
Required
Determine if there's a direct variation between the number and its position
I'll start by giving an illustration of how the triangle is represented using stars (*)
*
**
***
****
*****
Represent the line number with y and it's position with x
On line 1:
y = 1, x = 1
On line 2:
y = 2, x = 3
On line 3:
y = 3, x = 6
On line 4:
y = 4, x = 10
On line 5:
y = 5, x = 15
Note that, x is gotten by calculating the accumulated number of stars while y is the line number.
Direct variation is represented by
y = kx
Or
kx = y
Where k is the constant of variation
For line 1:
Substitute 1 for y and 1 for x
k * 1 = 1
k = 1
For line 2:
Substitute 2 for y and 3 for x
k * 3 = 2
Divide through by 3
k = ⅔
Note that the values of k in both computations differ.
This implies that there's no direct variation and there's no need to check further.
