Answer:

A = 2.83 feet²

Step-by-step explanation:

From the attached figure,

Length of the cube, l = 1.5 ft

Breadth of thecube, b = 0.5 ft

Height of the cube, h = 4 inches

We need to find the surface area of this figure.

We know that : 1 foot = 12 inch

4 inches = 0.334 foot

It is in the form of a cubiod. The formula for the surface area of a cuboid is given by :

A = 2(lb+bh+hl)

Put all the values in the above formula :

A = 2(1.5×0.5+0.5×0.334 +0.334×1.5)

A = 2.83 feet²

So, the surface area of this figure is 2.83 feet².

Answer:

We conclude that all the pairs of points have positive slopes.

Thus, there is NO pair of points that has a negative slope.

Step-by-step explanation:

a)

Determining the slope between (-10, -3), (-7, 6)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-10,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-7,\:6\right)[/tex]

[tex]m=\frac{6-\left(-3\right)}{-7-\left(-10\right)}[/tex]

[tex]m=3[/tex]

b)

Determining the slope between (7, 7), (-8, 1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{1-7}{-8-7}[/tex]

[tex]m=\frac{2}{5}[/tex]

c)

Determining the slope between (5,2), (-9,-10)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{-10-2}{-9-5}[/tex]

[tex]m=\frac{6}{7}[/tex]

d)

Determining the slope between  (2,9), (-3,-1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{-1-9}{-3-2}[/tex]

[tex]m=2[/tex]

We conclude that all the pairs of points have positive slopes.

Thus, there is NO pair of points that has a negative slope.

Answer:

Step-by-step explanation:

Ok, first put the equation into y=mx+b form

3x-2y=2

subtract 3x from both sides

-2y=-3x+2

divide by -2

y=3/2x-1

Parallel lines have the same slope, but a different y intercpet.

So the new equation so far is y=3/2x+b

Since the line has to pass through the given point, substitute (-6,-2) into the equation

-2=3/2(-6)+b

-2=-9+b

7=b

so the line is y=3/2x+7

Answer:

2(30) + 2x = 245

Step-by-step explanation:

As u know a rectangle has four sides, two equally long sides and two equally short sides. If each of the short sides are 30, that means 30 times 2 adding the 2 missing long sides would equal 245. So the long sides are going to be represented with x in this equation:

2(30) + 2x = 245

To make sure our equation is right, lets try solving it:

2(30) + 2x = 245

60 + 2x = 245

subtract 60 from both sides

2x = 185

x = 92.5

Now put 92.5 in the equation instead of x to confirm:

2(30) + 2(92.5) = 245

60 + 185 = 245

245 = 245

Answer:

Step-by-step explanation:

1 is also known as 8/8, because anything that has all the parts to it is a whole.

Meaning, we can change this equation into 8/8-3/8, which makes it much easier.

With that, if you subtract the numerators, 8-3,  you get 5. In other words, you are subtracting three "pieces" from the eight "pieces". You end up with 5 of the original 8 "pieces", or 5/8.

Answer:

2x + 11

$706.82 total cost for laptop

Step-by-step explanation:

$652.95 x .0825 = $53.868.    (Move decimal twice to the left to change % to decimal)

$652.95 + $53.868 = $706.818 = $706.82

Answer:

smaller number is 10

larger number is 39

Step-by-step explanation:

a = small number

b = larger number

a + b = 49

2a = 3b - 97

substitute 49-a into second equation for b

2a = 3(49-a) - 97

2a = 147 - 3a - 97

5a = 50

a = 10

b = 39

there is an error in step 2

8 should have multiplied with x and -1, but at the end the answer is the same so I guess it can be all corect or the error in step 2

Step-by-step explanation:

I can't show the pencil or paper :/

1180(4) = 4720

4720/4 = 1180

In a company, there are 5,900 workers can work.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

In a company, 80% of the workers are men.

And, 1,180 people work for the company who aren't men.

Let total workers in a company = x

So, we can formulate;

In a company, 80% of the workers are men.

⇒ 20% of workers are not men's.

Here, 1,180 people work for the company who aren't men.

Hence, We get;

⇒ 20% of x = 1180

⇒ 20 / 100 × x = 1180

⇒ 20x = 1180 × 100

⇒ x = 1180 × 5

⇒ x = 5900

Answer:

Cost = $51.96

Step-by-step explanation:

The radius of a regular hexagonal window, r = 2 feet

The area of a hexagonal shaped figure is given by :

[tex]A=\dfrac{3\sqrt3}{2}r^2[/tex]

Put r = 2 feet in above formula

[tex]A=\dfrac{3\sqrt3}{2}\times (2)^2\\\\A=10.392\ \text{unit}^2[/tex]

Replacement glass for energy-efficient windows costs $5.00 per square foot. It means, the total cost will be :

[tex]A=10.392\times 5\\\\A=\$51.96[/tex]

So, the required cost will be $51.96. Hence, the correct option is (d).

Answer:

x = 15/7

Step-by-step explanation:

-7x - 3 = 12

    -7x = 12 + 3

    -7x = 15

       x = 15/7

Hope this helps :) Pls mark Brainliest!

Answer:

x = -15/7

Step-by-step explanation:

1. First we need to add 3 to both sides, and then evaluate.

−7x − 3 + 3 = 12 + 3

= −7x − 3 + 3 = 15

= −-10x + 3 = 15

= −7x=15

2.  Now we need to divide both sides by -7

-7x/-7 = 15/-7

x = -15/7
