There are 9.5 ounces of juice in a container. an additional 1.75 ounces of juice are poured into the container each second. how many ounces of juice are in the container after 6 seconds? enter your answer in the box. ounces
For this case, the first thing we must do is define variables.
We have then:
x: time in seconds
y: number of ounces
We then have an equation of the form:
[tex] y = mx + b
[/tex]
Where,
b: initial amount of juice
m: amount of juice added every second.
Substituting values we have:
[tex] y = 1.75x + 9.5
[/tex]
For 6 seconds later we have:
[tex] y = 1.75 (6) +9.5
y = 20
[/tex]
Answer:
20 ounces of juice are in the container after 6 seconds

What is the y-intercept of the equation 5x - 6y = 18?
A.-6
B. -3
C .5
D. 18
The y-intercept is for x = 0.
Put the value of x = 0 to the equation 5x - 6y = 18:
5(0) - 6y = 18
0 - 6y = 18
-6y = 18 divide both sides by (-6)
y = -3 → B.

A local company manufactures netbook computers. Their profit function is given by this equation: y equal minus x to the power of 2 plus 120 x plus 3000 where x is the number of netbooks produced in one day and y is the profit (in dollars) the company makes that day. What is the maximum profit that the company can make? (Hint: Find the vertex of the parabola.)
Answer: $6,600
Step-by-step explanation:
Given: The profit function is given by the equation:
[tex]y=-x^2+120x+3000[/tex],where x is the number of netbooks produced in one day and y is the profit (in dollars) the company makes that day.
To find the maximum profit, first we need to find critical point of the function.
For that, first differentiate the above function w.r.t. x, we get
[tex]y'=-2x+120[/tex]
Now, Put [tex]y'=0[/tex], we get
[tex]-2x+120=0\\\\\Rightarrow\ x=60[/tex]
Again differentiate the above function w.r.t. x, we get
[tex]y"=-2<0[/tex]
By second derivative test, at x=60 , attains its maximum value.
Now, the Maximum profit will be :
[tex]y=-(60)^2+120(60)+3,000=6,600[/tex]
Hence, the maximum profit that the company can make = $6,600

A forester wants to estimate the height of a tree. He is 6 ft tall and cast a shadow of 4 ft. If the shadow of the tree is 60 ft, how tall is the tree?
Answer:
90 ft
Step-by-step explanation:
Given,
The 6 ft tall man casts 4 ft long shadow,
So, the ratio of the height of the man and its shadow = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]
Now, suppose the height of the tree that casts the shadow of 60 ft long is h ft,
So, the ratio of the height of tree and its shadow = [tex]\frac{h}{60}[/tex]
At the same time,
[tex]\frac{h}{60}=\frac{3}{2}[/tex]
[tex]h=60\times\frac{3}{2}=30\times 3=90[/tex]
Hence, the height of the tree is 90 ft

CDs and DVDs Solve by setting up a system of linear equations with 2 variables and 2 unknowns. CDs cost $5.96 more than DVDs at All Bets Are Off Electronics. How much would 6 CDs and 2 DVDs cost if 5 CDs and 2 DVDs cost $127.73?
The relationship between the total cost and the costs of CDs and DVDs are represented by a linear function.
The cost of 6 CDs and 2 DVDs is $147.68
Let:
[tex]C \to CDs[/tex]
[tex]D \to DVDs[/tex]
From the question, we have:
[tex]C = D + 5.96[/tex]
[tex]5C + 2D = 127.73[/tex]
Substitute [tex]C = D + 5.96[/tex] in [tex]5C + 2D = 127.73[/tex]
[tex]5 \times (D + 5.96) + 2D = 127.73[/tex]
[tex]5D + 29.8 + 2D = 127.73[/tex]
Collect like terms
[tex]5D + 2D = 127.73 - 29.8[/tex]
[tex]7D = 97.93[/tex]
Divide both sides by 7
[tex]D = 13.99[/tex]
Substitute [tex]D = 13.99[/tex] in [tex]C = D + 5.96[/tex]
[tex]C = 13.99 + 5.96[/tex]
[tex]C = 19.95[/tex]
The cost of 6 CDs & 2 DVDs is represented as:
[tex]Cost =6C + 2D[/tex]
So, we have:
[tex]Cost =6 \times 19.95 + 2 \times 13.99[/tex]
[tex]Cost =147.68[/tex]
Hence, the cost of 6 CDs & 2 DVDs is $147.68

The [tex]\angle[/tex]C is [tex]77^o[/tex] in the triangle ABC inscribed in the circle as evident from the figure.
A triangle is a polygon with three angles, three edges, and three vertices. It's one of the most introductory and abecedarian shapes in geometry.
Triangles can be classified by their side lengths, their angles, or their symmetry.
As the angle on the circumference is double the angle on the semicircle,
therefore,
[tex]\angle[/tex]B = [tex]\frac{110^o}{2}[/tex]
= [tex]55^o[/tex].
As the sum of a triangle is [tex]180^o[/tex],
So,
[tex]\angle[/tex]A + [tex]\angle[/tex]B + [tex]\angle[/tex]C = [tex]180^o[/tex],
Given that [tex]\angle[/tex]A = [tex]48^o[/tex],
[tex]48^o[/tex] + [tex]55^o[/tex] + [tex]\angle[/tex]C = [tex]180^o[/tex],
[tex]\angle[/tex]C = [tex]180^o[/tex] - [tex]48^o[/tex] - [tex]55^o[/tex],
[tex]\angle[/tex]C = [tex]77^o[/tex]
So, the [tex]\angle[/tex]C is [tex]77^o[/tex].

Each baby dinosaur made 15 paintings and each adult dinosaur made 7 paintings. The entire herd made 208 paintings in total, and there were 3 times as many baby dinosaurs as adult dinosaurs.
Answer:
Adult dinosaurs=4
Baby Dinosaurs=12
Step-by-step explanation:
You only have to put an X to a certain number, in this case it will be like this:
Adult dinosaurs=x
Baby Dinosaurs= 3x
So the equation will be:
15(3x)+7(x)=208
You multiply it and add it and it will end up like this:
52x=208
x=4
So there were 4 adult dinosaurs.
And baby dinosaurs there are 3x which equals 12.

nate had 88.65 to convert into shekalim. the currency exchange he is using charges an 8% surcharge when converting currency. about how many more shekalim will nate recieve if he makes his trade on the day with the most favorable exchange rate than if he makes his trade on yhe day with the least favorable exchange rate?
Possible Answers
A. INS 41.69
B. INS 38.35
C. INS 31.68
D. INS 6.67
The correct answer is:
B) INS 38.35
Explanation:
The day with the best exchange rate is Friday; the rate is 1:6.1715. Converting 88.65£ with this rate, we have:
88.65(6.1715) = 547.103475.
Since he is charged an 8% surcharge, he gets to keep 100%-8% = 92% = 92/100 = 0.92 of this:
0.92(547.103475) = 503.335197
The day with the worst exchange rate is Wednesday, with a rate of 1:5.7012. Converting 88.65£ at this rate,
88.65(5.7012) = 505.41138. 4
0.92(505.41138) = 464.9784696
The difference between Friday and Wednesday is:
503.335197-464.9784696 = 38.3567274, or 38.35.
Nate would receive about 38.35 more shekalim if he made his trade on the day with the most favorable exchange rate than if he made his trade on the day with the least favorable exchange rate.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The day with the best exchange rate is Friday; the rate is 1:6.1715. Converting 88.65£ with this rate, we have:
88.65(6.1715) = 547.103475.
Since he is charged an 8% surcharge, he gets to keep 100%-8% = 92% = 92/100 = 0.92 of this:
0.92(547.103475) = 503.335197
The day with the worst exchange rate is Wednesday, with a rate of 1:5.7012.
Converting 88.65£ at this rate,
88.65(5.7012) = 505.41138. 4
0.92(505.41138) = 464.9784696
The difference between Friday and Wednesday is:
503.335197-464.9784696 = 38.3567274, or 38.35.
Hence, Nate would receive about 38.35 more shekalim if he made his trade on the day with the most favorable exchange rate than if he made his trade on the day with the least favorable exchange rate.
