Answer:

48.02 or 48 1/50 cubic feet and 3193.33 or 3193 33/100 LB ( I do rsm too )

Step-by-step explanation:

The width is 3.5

The length is 3.5*7/5 which is 4.9

The height is 4/5 of 3.5 which is 2.8

So, the volume in cubic feet is 3.5*4.9*2.8 which is 48.02 or 48 1/50

So, the amount in Lb is 66.5*48.02 which is 3193.33 or 3193 33/100

A rectangular prism is a three-dimensional solid object that has six rectangle-shaped faces.

Length of a rectangular prism [tex](l)=3.5[/tex] feet

Width of a rectangular prism [tex](w)=\frac{5}{7}(3.5)[/tex]

                                               [tex]=2.5[/tex] feet

Height of a rectangular prism [tex](h)=\frac{4}{5}(3.5)[/tex]

                                                  [tex]=2.8[/tex] feet

Volume of a milk tank [tex]=lwh[/tex]

                                     [tex]=3.5(2.5)(2.8)[/tex]

                                     [tex]=\boldsymbol{24.5}[/tex] cubic feet

                                    [tex]=24.5(66.5)[/tex] pounds

                                    [tex]=\boldsymbol{1629.25}[/tex] pounds

So, a tank can hold [tex]\boldsymbol{24.5}[/tex] cubic feet of milk and a tank can hold [tex]\boldsymbol{1629.25}[/tex] pounds.

Answer: 5 hours

Step-by-step explanation:

The car has already travelled 25 miles into the 200 miles that it is meant to travel.

The distance left is therefore:

= 200 - 25

= 175 miles

The car is travelling at 35 miles per hour.

The time left for travel is:

= Distance /  Speed

= 175 / 35

= 5 hours

Step-by-step explanation:

Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.

Step-by-step explanation:

First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).

For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.

While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.

Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.

For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Answer:

(1.5, -2)

Step-by-step explanation:

First subract -3 from 6 to find the total distance of the line segment.

6 - (-3)

Two negatives make a positive

6 + 3

9 units distance

Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.

-3 + 4.5

-3 + 3 + 1.5

(1.5, -2)

6 - 4.5

6 - 4 - 0.5

2 - 0.5

(1.5, -2)

The midpoint of segment RS is (1.5, -2).

Answer:

$480

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Original cost including sales tax = $1,200

Discount = 60%

So, we can calculate the cost of TV after discount by using following formula:

Cost of TV after discount =  $1,200 - ( $1,200 × 60%)

= $1,200 - $720

= $480

Hence, Cost of TV after discount is $480.

Given:

The given system of equation is:

[tex]y=-2x+1[/tex]

[tex]4x+2y=-3[/tex]

To find:

The solution of given system of equations using subtraction.

Solution:

We have,

[tex]y=-2x+1[/tex]             ...(i)

[tex]4x+2y=-3[/tex]         ...(ii)

First equation can be rewritten as

[tex]2x+y=1[/tex]             (Adding 2x on both sides)

[tex]4x+2y=2[/tex]       ...(iii)        (Multiplying both sides by 2)

After subtracting (ii) from (iii), we get

[tex]4x+2y-(4x+2y)=2-(-3)[/tex]

[tex]4x+2y-4x-2y=2+3[/tex]

[tex]0=5[/tex]

This statement is false because [tex]0\neq 5[/tex]. It means, there is no value of x and y for which the given system of equations are true.

Therefore, the given system of equations has no solution and the correct option is b.

Answer:

19 cents

Step-by-step explanation:

Natalie buys 4 buttons at 3 cents each. She also buys 1 zipper at 7 cents

We are to find the total amount that she spends for each costume

I converted cents to dollars.

4 buttons at 3 cents = 4x0.03 (3 cents is 0.03 dollars)

= 0.12

The zipper = 7 cents = 0.07 dollars

The total amount she spent = 0.12+ 0.07

= 0.19 dollars = 19 cents

Therefore she 19 cents in total for each costume

4 buttons at

Answer:

2y + 2z

6x³+2x²-10 + 2x²-24

6x³+4x²-34 ■

Step-by-step explanation:

The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.

Here, y = 3x³+x²-5 and z = x²-12

Now,

2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )

2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )

2 ( y + z ) = 6x³ + 4x² - 34

Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
