It's a 1x2x3 box, aka parallelepiped.  So we have 2 1x2 faces, 2 2x3 faces and 2 1x3 faces.  We add them up:

A = 2(1 × 2 + 2 × 3 + 1 × 3) = 2(2+6+3) = 22

Answer: d. 22

What is the slope?<br>if possible can you explain?​
Mandarinka [93]

Answer:

m =  \frac{4}{5}

Step-by-step explanation:

The slope of a graph is also known as its gradient, which is the steepness of the graph.

If we are given two points on the line, we can find the slope by taking rise/ run, which is the ratio of the change in y-coordinate against the change in the x-coordinate. This can also be written as a formula:

\boxed{slope =  \frac{y1 - y2}{x1 - x2} }

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

In this question, we are given the equation of the line. This equation is already in the slope-intercept form (y= mx +c) since the coefficient of y is 1 and all the other terms are on the other side of the equal sign. In the slope-intercept form, m is the slope while c is the y-intercept.

m= ⅘ since the coefficient of x is ⅘ in the given equation (when the equation is in the slope-intercept form).

Lourdes plans to jog at least 1.5 miles. Write an inequality and solve an inequality to find x, the number of hours Lourdes will
Paraphin [41]

Answer:

1.5 ≤ 3.75x

Step-by-step explanation:

Given that:

Distance, D to jog is atleast 1.5 miles

D ≥ 1.5 miles

x = number of hours to jog

Jog rate = 3.75 mph

Actual distance covered if jog last for X hours

Actual Distance = speed * time

Actual Distance = 3.75 * x = 3.75x

Hence,

D ≤ Actual distance

1.5 ≤ 3.75x

I need help with this work
Anton [14]

Answer:

Please find the answer in the image attached

Step-by-step explanation:

Here we are asked to solve a pair of linear inequalities.

In order to do so , we are first required to plot the two lines with inequalities taking into considerations.

Hence let us plot

x+2y=-4 and 5x+2y=4

let us first plot x+2y=-4

y=\frac{-4-x}{2}

let us plot a table for the same for two random values of x and putting them into above equation

x     y

0    -2

2    -3

Let us now plot these points and join the line .

Let us check whether (0,0) satisfies the in equation or not

0+2(0)≤-4

0≤-4

Which is not true , Hence we shade the portion divided by our line which does not contain (0,0)

Now let us plot the second line 5x+2y=4

y = \frac{4-5x}{2}

let us plot a table for the same for two random values of x and putting them into above equation

x     y

0     2

1     -0.5

Let us now plot these points and join the line .

Let us check whether (0,0) satisfies the in equation or not

5(0)+2(0)≤4

0≤4

Which is true , Hence we shade the portion divided by our line which does  contain (0,0)

Please refer to the image attached with this answer.

now the commonly shaded area as shown in the image will be our solution to the above pair of in equations.
