Answer:
8/1.50 = 128/x
Step-by-step explanation:
In this case, I put the amount of fruit drink over the cost!
8 ounces/$1.50
there are 128 ounces in a gallon and we want to find out the cost of a gallon, so we can put that as x!
128 ounces/x
There's your proportion! Hope this helps :)
What is the equation of the line that passes through the point ( -1, 1) and is perpendicular to 2x + 4y = 16?
A. y = −2x − 1
B. y − 3 = 2x
C. y = 6x + 7
D. Cannot be determined
Answer:
B
Step-by-step explanation:
We want the equation of the line that passes through the point (-1, 1) and is perpendicular to:
[tex]2x +4y=16[/tex]
Remember that the slopes of perpendicular lines are negative reciprocals of each other.
So, let's find the slope of the original line first. We can do so by converting it to slope-intercept form. Thus:
[tex]4y=-2x+16[/tex]
Therefore:
[tex]\displaystyle y=-\frac{1}{2}x+4[/tex]
The slope is -1/2.
The negative reciprocal of -1/2 is 2.
Thus, the slope of our new line is 2.
The slope is 2 and it passes through the point (-1, 1).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]y-(1)=2(x-(-1))[/tex]
Distribute:
[tex]y-1=2x+2[/tex]
Subtracting 2 from both sides yields:
[tex]y-3=2x[/tex]
Therefore, our answer is B.

What is a word problem?
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Let the two numbers be x and y.
Two numbers have a negative sum, but a positive product.
So, the two numbers are -x and -y.
Let us consider the two numbers be -2 and -3
Sum of two numbers = [tex]-2+(-3)[/tex]
⇒ [tex]-5[/tex]
Product of two numbers = [tex](-2)(-3)[/tex]
⇒ [tex]6[/tex]
Thus the sum have a negative number and the product is a positive product.

A 12 foot ladder is leaning against a house. The bottom of the ladder is 3 ft from
the house. How high does the top of the ladder reach? Round to the nearest
tenth.
Answer:
h = 11.61 foot
Step-by-step explanation:
Given that,
The length of a ladder, l = 12 foot
The bottom of the ladder is 3 ft from the house.
We need to find how high does the top of the ladder reach. Let it is h. The length of the ladder will be the hypotenuse. 3 ft will be the base. So,
[tex]12^2=3^2+h^2\\\\h^2=144-9\\\\h=11.61\ \text{foot}[/tex]
So, the top of the ladder is at a height of [tex]11.61\ \text{foot}[/tex].

If you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Complete question :
Mitch is making birdhouses to sell. He needs to make at least $678. Each birdhouse costs $28 to make. He is selling them for $40 each. What is the minimum he can sell to reach his goal?
Answer:
57
Step-by-step explanation:
you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Target profit = $678
Expenses per product = $28
Income per sale = $40
Profit per sale = $(40 - 28) = $12
Let number of sales or product = x
Hence,
$12 * x ≥ 678
12x ≥ 678
x ≥ 678 / 12
x ≥ 56.5
To the nearest whole number = 57

The line of best fit can be written as:
y = mx + c
Here m is the slope of the line best fit and c is the y-intercept
Putting the values in the formula we get:
m = 0.15
c = -23.21
The line of best fit is:
y = 0.15x - 23.21
Thus, the line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.

HELP “The vertical supports in this truss bridge are built so that
AABO=AOCD. Which of the following statements
is NOT true?”
Answer:
The statement that is not true is;
c) m∠ABO = m∠ODC
Step-by-step explanation:
With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;
Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD
Vertices B and C on ΔABO and ΔOCD are corresponding vertices
Therefore;
Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively
Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD
Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD
Therefore;
m∠ABO = m∠OCD by definition of congruency

What is the equation for the nth term of the sequence
And what is the 52nd term of the sequence. -8,-12,-16
Given:
The sequence is -8, -12, -16.
To find:
The nth and 52th term of the given sequence.
Solution:
We have,
-8, -12, -16
It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is
[tex]r=a_2-a_1[/tex]
[tex]r=-12-(-8)[/tex]
[tex]r=-12+8[/tex]
[tex]r=-4[/tex]
The nth term of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is first term and d is common difference.
Putting a=-8 and d=-4, we get
[tex]a_n=-8+(n-1)(-4)[/tex]
[tex]a_n=-8-4n+4[/tex]
[tex]a_n=-4-4n[/tex]
Putting n=52, we get
[tex]a_{52}=-4-4(52)[/tex]
[tex]a_{52}=-4-208[/tex]
[tex]a_{52}=-212[/tex]
Therefore, the equation for the nth term of the given sequence is [tex]a_n=-4-4n[/tex] and the 52nd term of the sequence is -212.
