The price of the jacket is $23.75
Let m be the price of a jacket and n be the price of pair of pants.
The total cost of a jacket and a pair of pants was $52.37
So, we get an equation,
m + n = 52.37 ................(1)
Also, the price of the jacket was $4.87 less than the pair of pants
So, we get an equation,
m = n - 4.87 .............(2)
Substitute above value of m in equation (1)
⇒ (n - 4.87) + n = 52.37
⇒ 2n - 4.87 = 52.37
⇒ 2n = 52.37 + 4.87
⇒ 2n = 57.24
⇒ n = 28.62
This means, the cost of a pair of pants is $28.62
Substitute above value of n in equation (2)
⇒ m = n - 4.87
⇒ m = 28.62 - 4.87
⇒ m = 23.75
This means, the cost of a jacket is $23.75
Therefore, the price of the jacket is $23.75

Use the table to write an expression that shows how many total baskets the Cavaliers made during the season. Simplify the expression.
The expression that shows how many total basket the Cavaliers made during the season is 1978+f
The total number of free throws = 1484
The number of two point field goals = f
The number of 3 point field goals = 494
Total number of basket Cavaliers made during the season = Number of free throws + Number of two point goals + Number of three point field goals
Substitute the values in the equation
Total number of basket Cavaliers made during the season= 1484 + f +494
Add them together
1484+ f +494= 1978+f
Hence, the expression that shows how many total basket the Cavaliers made during the season is 1978+f

The amount of oil imported to Country A from Country B in millions of barrels per day can be approximated by the equation y=0.051x+1.38, where x is the number of years since 1970. Solve this equation for x. Use the new equation to determine in which year the approximate number of oil barrels imported from Country B per day will be 1.89 million.
First, solve the equation for x.
algebraic equation solving x, we concluded that In the year 1980 the approximate number of oil barrels imported from Country B per day will be 1.89 million.
What exactly is a mathematical linear equation?An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.
Given the equation is :y=0.051x+1.38
Let us put y = 1.89
1.89 = 0.051x + 1.38
⇒ x = 0.51/0.051
⇒ x = 10
After ten years, 1.89 million oil barrels per day will be roughly imported from Country B.
Around 1.89 million oil barrels per day would be imported from Country B in the year 1980.

The value of the ratio to fill in the following two multiplicative comparison statements are:
(A) The number of pancakes made is 5 times the amount of flour required. (B) The amount of flour required is 1/5 of the number of pancakes made.What do we mean by ratio?A ratio in mathematics indicates how many times one number contains another. For example, if a bowl of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six (that is, 8:6, which is equivalent to the ratio of 4:3). Similarly, the proportion of lemons to oranges is 6:8 (or 3:4), and the proportion of oranges to total fruit is 8:14. (or 4:7).The number of pancakes made is five times the amount of flour required. The amount of flour required is one-fifth of the number of pancakes made.Therefore, the value of the ratio to fill in the following two multiplicative comparison statements are:

A graphic designer enlarges a 12 inch long picture to a 2 1/2 foot long banner. At this setting if the picture is 16 inches wide how wide is the banner
Based on the enlargement the graphic designer applied to the length of the picture, the banner is as wide as 3 ⁸/₁₂ foot long
What is the width of the banner?The fact that 12 inch was enlarged to 2.5 foot means that every inch is:
= 2.5 / 12
= 2.5/12 foot
This means that if the picture was 16 inches wide, the enlarged size of the banner would be:
= 16 x 2.5/12
= 40 / 12
= 3.33
= 3 ⁸/₁₂ foot long

Classify each of the following statements as true or false. If false, tell why. a. 5 is a divisor of 20. b. 10 is a multiple of 20.
Answer:
Yes; no
Step-by-step explanation:
a. If we divide 20 by 5, we get 4. Meaning, both 4 and 5 are divisors of 20.
b. 10 is not a multiple of 20; The multiples of 20 are 20, 40, 60, 80, 100, 120, 140, etc. Multiples only go upwards not down. Nothing plus 20 is equal to 10 therefore 10 is not a multiple of 20. 20 is a multiple of 10 though.
square root of 72/98
Answer:√78= 8.9 √98= 9.9
Step-by-step explanation:
Answer:
6/7
Step-by-step explanation:
So first, we can simplify 72/98. If we divide both the numerator and denominator by 2, to get a simplified fraction. So we need to solve 72/2 and 98/2. 72/2 = 36 and 98/2 = 49 So now we have a simplified fraction. So now, we are left with the square root of 36/49, and we apply the radical rule. So now we have simplified radicals that make things easier. The square root of 36 is 6, while the square root of 49 is 7. This is because 36 can be broken down into factors of 6 and 6, so like 6^2 = 36. So square root of 36 is 6. While 49 can be broken down as 7 and 7, so like 7^2 = 49, so square root of 49 is 7. Therefore our answer is 6/7.

how to increase the accuracy of simpson rule and maclaurin series expansion respectively?
Because it matches a parabola to the curve rather than a straight line, Simpson's rule is more precise.
The other approaches are only accurate for functions whose graphs are linear, whereas Simpson's rule yields the exact area beneath the graphs of functions of degree two or less (parabolas and straight lines).Why is trapezoidal less accurate than Simpson's rule?
When the underlying function is smooth, Simpson's Rule is more accurate than the trapezoidal rule because it employs quadratic approximations rather than linear ones. In cases where there are an odd number of evenly spaced points, the formula is typically provided.What are Simpson's rule's restrictions?
It is obviously incorrect because the actual integral will always differ from it (except in some cases, such as the area under straight lines). Integrals, unlike Simpson's technique, allow you to obtain precise results in terms of basic constants.Learn more about Simpson's Rule

w = −1.3
w = 1.3
w = 5.6
w = 13.34
Answer:
d. w=13.34
Step-by-step explanation:
The value of w is 13.34 for the given equation. The correct answer is option D.
What is the solution to the equation?A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
The equation is given as follows:
3(−5.8 + w) = 22.62
First, we distribute the 3 on the left side of the equation:
-17.4 + 3w = 22.62
Next, we isolate the variable by adding 17.4 to both sides of the equation:
-17.4 + 3w + 17.4 = 22.62 + 17.4
3w = 40.02
Finally, we solve for w by dividing both sides of the equation by 3:
w = 13.34
Therefore, the value of w is 13.34, so the answer is option D.

14. The maximum capacity for seating in a theater is 500 people. The theater sells two types of tickets, adult tickets for $7.25 each and child tickets for $4 each. If they sold out on a certain showtime and made a total of $3,157 in ticket sales, how many of each types of tickets was sold out that showtime?
Step-by-step explanation:
set x as the number of the adults in the show
500-x - number of children
(500-x)×4+7.25x=3157
2000-4x+7.25x=3157
3.25x=1157
3×1/4x=1157
13/4x=1157/×4
13x=4628/÷13
x=356
356 adult tickets was sold out.
500-356=144
144 child tickets was sold out.
Answer:
Adult tickets sold = 356
Child tickets sold = 144
Step-by-step explanation:
Given information:
Maximum number of seats = 500Cost of adult ticket = $7.25Cost of child ticket = $4Total revenue of sold-out show = $3,157Define the variables:
Let x = the number of adult tickets sold.Let y = the number of child tickets sold.Create two equations from the given information:
[tex]\textsf{Equation 1}: \quad x + y = 500[/tex]
[tex]\textsf{Equation 2}: \quad 7.25x+4y=3157[/tex]
Rewrite Equation 1 to make y the subject:
[tex]\implies y=500-x[/tex]
Substitute this into Equation 2 and solve for x:
[tex]\implies 7.25x+4(500-x)=3157[/tex]
[tex]\implies 7.25x+2000-4x=3157[/tex]
[tex]\implies 3.25x+2000=3157[/tex]
[tex]\implies 3.25x=1157[/tex]
[tex]\implies x=356[/tex]
Substitute the found value of x into the rewritten form of Equation 1 and solve for y:
[tex]\implies y=500-356[/tex]
[tex]\implies y=144[/tex]
