Answer:

Step-by-step explanation:

The region R is bounded below by y=1 and above by f(x) where

[tex]f(x)=\begin{cases}3,&1\leq x\leq 2\\\\-x+5,&2\leq 3\end{cases}[/tex]

and we integrate the R over the interval [1,3]

A.

[tex]V=\int_1^3 \pi(f(x)^2-1^2)\, dx\\V=\int_1^2 \pi(3^2-1^2)\, dx +\int_2^3 \pi((-x+5)^2-1^2)\, dx\\=9\pi + \int_2^3 \pi(x^2-10x+24)\, dx\\=9\pi +\pi\left({[(1/3)x^3-5x^2+24x]_2^3\right)\\=9\pi + \pi( (19/3) -25 +24)\\=9\pi +(16/3)\pi=43/3 \pi.[/tex]

For part B

[tex]V=\int_1^3 2\pi x(f(x)-1)\, dx[/tex]

and you can compute the integral similarly as above, just split the integral into two integrals, one over [1,2] and the other is over [2,3].

Answer:

third angle = (-6x + 161)°

Step-by-step explanation:

180° = (x)° + (5x + 19)° + third angle →

180° = (6x + 19)° + third angle →

180° – (6x + 19)° = (6x + 19)° + third angle – (6x + 19)° →

180° – (6x + 19)° = third angle →

180° + -(6x + 19)° = third angle →

180° + (-6x)° + (-19)° = third angle

180° – 6x° – 19° = third angle

(180° – 19°) – 6x° = third angle

161° – 6x° = third angle

third angle = 161 – 6x°

third angle = -6x° + 161°

third angle = (-6x + 161)°

The fraction 1/4 can be rewritten as the division expression: 1 ÷ 4.

Fraction: 1/4

To rewrite this fraction as a division expression, we can simply put the numerator (1) as the dividend and the denominator (4) as the divisor:

Division Expression: 1 ÷ 4

In this expression, the number 1 is being divided by the number 4, which is equivalent to the fraction 1/4.

So, the detailed solution is that the fraction 1/4 can be represented as the division expression 1 ÷ 4.

Answer:

10

Step-by-step explanation:

So you start with

0.10x+0.25(24-x)=4.50

First you do the parenthesis

.25x24 is 6.

So

.10x+6-.25x=4.5

Combine like terms

-.15x+6=4.5

Now isolate the x so you can find what x is

4.5-6

-.15x=-1.5

Then divide

-1.5/-.15

The two negatives make it positive

So 1.5/0.15

Comes to 10.

x=10

The 10 comes like this .15 is 15/100

Simplify that to 3/20

1.5 is 15/10

Simplify that to 3/2

Then divide those

3/2 ÷ 3/20

You cant divide fractions so flip the other side and multiply

3/2 × 20/3

60/6

10

Answer:

2 1/4

Step-by-step explanation:

First you have to do 2 x 1 = 2

Then add 2 + 1 = 3

Next do 3/2 x 3/4

You will have to find the common denominator which is 8

Do 4 x 3 = 12 and 3 x 2= 6

Add 12 + 6 = 18

You get the answer 18/8

You can go and put this answer into an improper fraction

2 2/8

Since 2/8 can be divided by 2

You will get an answer of 2 1/4

Answer:

4 1/8

Step-by-step explanation:

first, you do 11 * 3/ 2* 4 which equals 33/8.

Answer:The cost would be 4.72

Step-by-step explanation: I copyed and pasted your question on another tab on brainly then found a answer that had how many lemmons they would need to buy.the () is how i know in there answer.

Total cost to buy required lemons = $ 2.8

Step-by-step explanation:

Selling price of each lemon = $0.35

One 9-inch lemon pie requires 0.5 cup of lemon juice

⇒ Two 9-inch lemon pie will require 2 × 0.5 = 1 cup of lemon juice

In general, One cup contains 16 tablespoons of juice

(Now, 2 tablespoons of juice is yielded by one lemon)

NOw, Cost of 1 lemon = $0.35

(Therefore, Cost of 8 lemons = 8 × 0.35 =$ 2.8)

Hence, Total cost to buy required lemons = $ 2.8

ignore the rest.

Then i looked up 8 times 0.59 and thats what i got.

Purchasing enough lemons to create two 9-inch lemon pies will cost $4.72.

The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

Given, the store is selling lemons at $0.59 each. Each lemon gives about 2 tablespoons of juice.

data gathered from the internet

1 cup = 16 tablespoons

To make one 9-inch Lemon pie there is 1/2 cup of Lemon juice required.

Thus, to make two 9-inch Lemon pies required lemon juice = 2*1/2 cup

to make two 9-inch Lemon pies required lemon juice = 1 cup

Since, 1 cup = 16 tablespoons

Thus,

to make two 9-inch Lemon pies required lemon juice = 16 tablespoon

given one lemon = 2 tablespoon juice

So, for 16 tablespoons of juice required lemon = 8

price of one lemon =  0.59

Price of 8 lemons = 0.59 * 8

the total price of 8 lemons or 16 tablespoons of lemon = 4.72

Thus,

to make two 9-inch Lemon pies required money = 4.72$

Therefore, it will cost $4.72 to buy enough lemons to make two 9-inch lemon pies.
