Answer:

If each of three people are given three-tenth of an apple shared, what fraction of the apple was received by the three people?

9/10

Explanation:

The given multiplication is 3 x 3/10

The word problem that can result to the mathematical expression 3 x 3/10 is:

<em>If each of three people are given three-tenth of an apple shared, what fraction of the apple was received by the three people?</em>

Since each of the people get 3/10 of the apple

The three people received a total share of 3 x 3/10 = 9/10r

What is the length of cloth needed to make 24 shirts if each shirt is made from .75 yards of material?

RideAnS [48]

Answer:

18 yards of material needed to make 24 shirts

Step-by-step explanation:

The unit rate is

1 shirt

------------------------------ = 1 1/3 shirts per yard of material = 4/3 shirt/yard

0.75 yards material

This rate could also be written as 3/4 yard per shirt

Multiply this latter rate by 24 shirts:

3 yard

-------------- * 24 shirts = 18 yards of material needed to make 24 shirts

4 shirt

Find the work done by force dield f(x,y)=x^2i+ye^xj on a particle that moves along parabola x=y^2+1 from(1,0) to (2,1)

NemiM [27]

Call the parabola $P$ , parameterized by $\mathbf r(y)=\langle y^2+1,y\rangle$ with $0\le y\le 1\rangle$ . Then the work done by $\mathbf f(x,y)$ along $P$ is

$\displaystyle\int_P\mathbf f(x,y)\cdot\mathrm d\mathbf r=\int_{y=0}^{y=1}\mathbf f(x(y),y)\cdot\dfrac{\mathrm d\mathbf r(y)}{\mathrm dy}\,\mathrm dy$
$=\displaystyle\int_0^1\langle(y^2+1)^2,ye^{y^2+1}\rangle\cdot\langle2y,1\rangle\,\mathrm dy$
$=\displaystyle\int_0^1(2y^5+4y^3+2y+ye^{y^2+1})\,\mathrm dy=\frac73-\frac e2+\frac{e^2}2$

What is the y and x intercept for f(x)=3x-2 find f(-5)

masya89 [10]

Answer: The y- intercept is -2. The x-intercept is 2/3

The attachment shows the solutions.

Step-by-step explanation: The y-intercept is the "b" term in the slope-intercept form of the equation. To find the x-intercept, substitute 0 for the output and solve for x.

0 = 3x -2 . Add 2 to both sides

2 = 3x . Divide both sides by 3

2/3 = x the x-intercept is 2/3

To find f(-5) substitute -5 for x and solve.

f(-5) = 3(-5) -2

f(-5) = -15 -2

f(-5) = -17
