The supply curve for steel is 90x−y=−50. The demand curve is 10x+y=200. x is quantity in thousands of metric tons y is price in dollars per metric ton What are the values for quantity and price at the intersection point of the two curves? To find the values, first use addition to combine the left sides and to combine the right sides of the two equations.
Answer:
The intersection point of the two curves is [tex](x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)[/tex].
Step-by-step explanation:
From statement we get the following equations:
Supply curve
[tex]90\cdot x - y = -50[/tex] (1)
Demand curve
[tex]10\cdot x + y = 200[/tex] (2)
Where:
[tex]x[/tex] - Quantity, measured in thousands of metric tons.
[tex]y[/tex] - Price, measured in US dollars per metric tons.
If we add both equations, then we find that quantity is:
[tex](90\cdot x -y )+(10\cdot x +y) = -50+200[/tex]
[tex]100\cdot x = 150[/tex]
[tex]x = \frac{3}{2}\,kton.m[/tex]
Then, we finally find the price by substituting on (2):
[tex]y = 200-10\cdot \left(\frac{3}{2} \right)[/tex]
[tex]y = 200-15[/tex]
[tex]y = 185\,USD[/tex]
The intersection point of the two curves is [tex](x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)[/tex].
a. {[(-15+5)×2+8]-32÷8}-(-7)
b. (5-2)³×2+[-4+(-7)]÷(-2+4)²
c. {-10-[12+(-3)²] + 3³}+3³}÷(-3)
I'll mark you brainliest if you solve these with explanation
Answer:
Step-by-step explanation:
The answers are:
A) {[(-15+5)×2+8]-32÷8}-(-7)
Calculate within parentheses: -16 - (-7)
Add and subtract (left to right): -16 - (-7) = -9
B) (5-2)³×2+[-4+(-7)]÷(-2+4)²
To solve this problem, you need to follow the steps of order of operations.
Calculate within parentheses: [tex]3^{3}[/tex] * 2 + [-4 + (-7)] ÷ (-2+4)²
Calculate within parentheses: [tex]3^{3}[/tex] *2 -11 ÷ (-2+4)²
Calculate within parentheses: 27 × 2 - 11 ÷ (-2+4)²
Calculate exponents: 27 × 2 -11 ÷ 4
Multiply and divide: 54 - 11 ÷ 4
Multiply and divide: 54 - [tex]\frac{11}{4}[/tex]
Add and Subtract: [tex]\frac{205}{4}[/tex]
Convert improper fractions to mixed numbers: [tex]\frac{205}{4}[/tex] = [tex]51\frac{1}{4}[/tex]
C) {-10-[12+(-3)²] + 3³}+3³}÷(-3)
Calculate within parentheses: -4 ÷ (-3)
Multiply and divide: [tex]\frac{-4}{(-3)}[/tex]
Simplify and convert improper fraction to a mixed number:
[tex]\frac{-4}{(-3)}[/tex] = [tex]\frac{4}{3}[/tex] = [tex]1\frac{1}{3}[/tex]

The triangle ΔABC is similar to the triangle ΔADE. Then the value of the variable 'x' will be 4 units.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
The triangle ΔABC is similar to the triangle ΔADE. Then the ratio of the corresponding sides will be constant. Then the equation is given as,
2 / (2 + x) = 1 / 3
Simplify the equation, then we have
2 / (x + 2) = 1 / 3
6 = (x + 2)
x = 6 - 2
x = 4

Answer:
A. 904.3 cm³
Step-by-step explanation:
Radius of the ice cream cone (r) = 6 cm
Height of the ice cream cone (h) = 12 cm
Radius of the shape of hemisphere formed by the half scope of ice cream = 6 cm
Total volume of ice cream = volume of cone + volume of hemisphere
= [tex] (\frac{1}{3} \pi r^2 h) + (\frac{2}{3} \pi r^3) [/tex]

64, degrees.
Answer:
If angle a and b are complementary angles, and angle a is 64, complementary equals 90, so 90-64= 26 degrees for angle b.
Angles ∠a and ∠b are complementary angles. Then the measure of the angle ∠b will be 64°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
The measure of the angle ∠a is 64°. And angles ∠a and ∠b are the complementary angles. Then the equation is given as,
∠a + ∠b = 90°
64° + ∠b = 90°
∠b = 26°
The measure of the angle ∠b will be 64°.

the measure of angle of a quadrilateral is 50 120 and 100 degree. find the measure of fourth angle
Answer:
The measure of the fourth angle is 90°.
Step-by-step explanation:
Let x be the measure of the fourth angle.
Given measures of the other angles : 50°,120° & 100°.
Knowledge Required :
The sum of all the interior angles of a quadrilateral is 360°.
Then,
50°+120°+100°+x=360°
⇒x = 360°-270°
⇒x = 90°
.°. x = 90°
Hence, the measure of the fourth angle is 90°.

Swanton Savings Bank pays 5.5% interest compounded quarterly on a regular savings account. John deposited $4400 in regular savings accounts for 1.5 years. How much interest did he earn?
Answer:
$375.71
Step-by-step explanation:
Given that:
Rate of interest = 5.5% compounded quarterly
Time = 1.5 years
Principal amount deposited in savings account = 1.5 years
To find:
Interest earned = ?
Solution:
Formula for amount with interest compounding quarterly:
[tex]A = P(1+\dfrac{r}{4\times 100})^{4t}[/tex]
Putting the values:
[tex]A = 4400(1+\dfrac{5.5}{4\times 100})^{4\times 1.5}\\\Rightarrow 4400\times 1.01375^6\\\Rightarrow 4400\times 1.085\\\Rightarrow \$ \bold{4775.71}[/tex]
Interest earned = Amount - Principal
Interest earned = 4775.70 - 4400 = $375.71

The cost of 5 pounds of boudin is $26.What is the constant of proportionality that relates the cost in dollars,y, to the number of pounds of boudin,x?
Given :
The cost of 5 pounds of boudin is $26.
To Find :
The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .
Solution :
Price per boudin in terms of x and y is :
[tex]P=\dfrac{y}{x}[/tex]
Price per boudin by given data :
[tex]P=\dfrac{26}{5}[/tex]
So,
[tex]\dfrac{y}{x}=\dfrac{26}{5}\\\\y = \dfrac{26}{5}x[/tex]
Therefore, the constant of proportionality is [tex]\dfrac{26}{5}[/tex].

Choose Yes or No to tell if the number 103 will make each equation true. 6.01 × □ = 601 No 0.305 × □ = 305 No 0.54 × □ = 540 No 0.097 × □ = 970 Yes
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equations :
6.01 × □ = 601 No 0.305 × □ = 305 No 0.54 × □ = 540 No 0.097 × □ = 970 Yes
Will the number 103 will make each true?
601 / 6.01= 100 (No, not true)
305 / 0.305 = 1000 (No, not true)
540 / 0.54 = 100 (No, not true)
970 / 0.097 = 10000 (No, not true)
Hence, multiplying each of the equation above by 103 will not make any of the equations true.

Given :
There are 40 DuBois students going on a field trip.
Each one pays their teacher $8.75 to cover admission to the museum and lunch.
Admission for the students is $120 and each one gets an equal amount to spend on lunch.
To Find :
How much will each DuBois student be able to spend on lunch.
Solution :
Amount they paid for admission :
[tex]P =\$ \dfrac{120}{40}\\\\P=\$3[/tex]
Now, amount of money to spend on lunch is $8.75 - $3 = $5.75 .
Hence, this is the required solution.
The $414 price charges a store for a small refrigerator consists of the refrigerator's original cost to the store plus a profit 15% what was the refrigerator's original cost to the store?
Answer:
$351.9Step-by-step explanation:
the question is not formatted well
A store charges $414 for a small refrigerator, the price consists of the refrigerator's original cost to the store plus a profit 15% what was the refrigerator's original cost to the store?
Step one:
given data
we are told that the price of the small refrigerator contains both the original price and 15% profit
mathematically
$414= original price + 15% profit
Step two:
let us solve for 15% of 414
=(15/100)*414
=0.15*414
=$62.1
This shows that the profit is $62.1
let the original price be x
$414= x + 62.1
solve for x
x=414-62.1
x=351.9
The refrigerator's original cost to the store $351.9
