Oi mans needs help

Answers

Answer:

3p

Step-by-step explanation:

4p + 2р - Зр

Combine like terms

6p -3p

3p

Answer:  3p

Think of 4p as having 4 pizzas

Adding on 2 more pizzas gets you 4p+2p = 6p

So we have 6 pizzas now.

Then we subtract off 3 pizzas

6p-3p = 3p

Leaving us with 3 left when everything is said and done

So,

4p + 2p - 3p = 6p-3p = 3p

Answer:

(8√2) / 15

Step-by-step explanation:

A curve bounded by the y-axis is represented by in terms of dy;

[tex]\int \:x\:dt[/tex]

When the curve crosses the y-axis, x will be 0. In this case x is the function of t, so we have to solve for x(t) = 0;

0 = t^2 + 2t --- (1)

Solution(s) => t = 0, t = 2

dy = (1/2 * 1/√t)dt --- (2)

Our solutions (0, 2) are our limits. The area of the curve is in the form [tex]A\:=\:\int _b^a\:f\left(t\right)g'\left(t\right)dt[/tex] , so now let's introduce the limits of integration, x(t) and dy/dt. Remember, dy/dt = (1/2 * 1/√t) (second equation). 1/2 * 1/√t can be rewritten as 1/2 * t^(-1/2)....

[tex]A\:=\:\int _2^0\:\left(t^2-2t\right)\left(\frac{1}{2}t^{-\frac{1}{2}}\right)dt\\\\= \int _2^0\:\left(\frac{1}{2}t^{\frac{3}{2}}-t^{\frac{1}{2}}\right)dt\\\\= \left[\frac{t^{\frac{5}{2}}}{5}-\frac{2t^{\frac{3}{2}}}{3}\right]_2^0\\\\= 0\:-\:\left(\frac{4\sqrt{2}}{5}-\frac{4\sqrt{2}}{3}\right)\\\\= \frac{8\sqrt{2}}{15}[/tex]

Your solution is 8√2 / 15

the scale is evenly balanced. explain how you could find the weight ( w ) of one turtle.

Answers

Answer:

count all of the weight on the right side, subtract 4 pounds from both sides, and divide it by 2.

Step-by-step explanation:

The weight of a turtle equals to 1+7=8unit. Remove 4 from each side since they both have one, now leaving 3 turtles on one side, whereas the other side has 3(1+7). Divided each side by 3, so one turtle has a weight of 8unit.

Robert earned $10, which was 4 less than twice what Eric earned , How much money did Eric earn?

Answers

Answer:

Eric's earning is $7

Step-by-step explanation:

Given

Represent Robert's earnings with R and Eric's with E.

[tex]R = 10\\R = 2E - 4[/tex]

Required

What is the value of E?

Substitute 10 for R in the second equation.

[tex]10 = 2E - 4[/tex]

Solve for 2E

[tex]2E = 10 + 4[/tex]

[tex]2E = 14[/tex]

Solve for E

[tex]E = 14/2[/tex]

[tex]E = 7[/tex]

Eric's earning is $7

Answers

Answer:

Step-by-step explanation:

3x - 4y = 13 (1)

2x + y = 5 (2)

——————

3x - 4y = 13

4(2x + y = 5) (2) times 4

——————-

3x - 4y = 13

8x + 4y = 20

——————-

11x = 33

x = 33/11

x = 3

Plug x = 3 in (2):

2(3) + y = 5

6 + y = 5

y = 5-6

y = -1

Thus, x = 3 and y = -1

-3x + 8 = 17 and 1 + 4x = -15

Answers

Answer:

1) x= -3

2) x=-4

Step-by-step explanation:

The first equation is :

-3x+8=17

solving for x

-3x=17-8 ------------by collecting like terms

-3x=9

Divide both sides by -3

-3x/-3=9/-3

x= -3

In the second equation

1+4x= -15

solving for x

4x=-15-1

4x = -16

x=-16/4

x= -4

The protein lysozyme unfolds at a transition temperature of 75.5C, and the standard enthalpy of transition is 509 kJ mol-1. Calculate the entropy of unfolding of lysozyme at 25.0C, given that the difference in the constant-pressure heat capacities upon unfolding is 6.28 kJ K-1 mol-1 and can be assumed to be independent of temperature. Hint: Imagine that the transition at 25.0C occurs in three steps: (i) heating of the folded protein from 25.0C to the transition temperature, (ii) unfolding at the transition temperature, and (iii) cooling of the unfolded protein to 25.0C. Because the entropy is a state function, the entropy change at 25.0C is equal to the sum of the entropy changes of the steps. In Beowulf, who do you think is a better representative of a hero?
