The volume of a right rectangular shipping carton is 948.75 cubic meters. The height of the shipping carton is 11 meters, and the width is 7.5 meters. What is the length of the shipping carton? Enter your answer as a decimal in the box.

Answers

11.5 meters I think.. took teh test

If volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that volume of a right rectangular shipping carton is 948.75 cubic meters.

The height of the shipping carton is 11 meters, and the width is 7.5 meters.

We have to find the length of the shipping carton

V=Length × width × height

V= Length x 7.5 x 11

948.75 = 82.5 length

Divide both sides by 82.5

Length = 948.75/82.5

Length = 11.5 meters

Hence, if volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.

-x+y=5 4x+y=10 Use addition to solve the linear system of equations. Include all of your work in your final answer

Answers

Answer:
x = 1
y = 6

Explanation:
The first given equation is:
-x + y = 5
Multiply this equation by -1, you will get:
x - y = -5 ............> I

The second given equation is:
4x + y = 10 ..........> II

Add the two equations I and II as follows:
x - y = -5
+ 4x + y = 10
..............................
5x = 5
Therefore:
x = 5/5
x = 1

Substitute with x in equation I to get y as follows:
x - y = -5
1 - y = -5
y = 1 + 5
y = 6

Lucy is a dress maker. She sews 4/7 of a dress in 3/4 hour. Lucy sews at a constant rate. At this rate, how many dresses does Lucy sew in one?

Answers

To find out how many dresses she can sew in one hour, divide the fraction of the dress she makes by the number of hours it takes for her to make the dress.

[tex]\sf\dfrac{4}{7}\div\dfrac{3}{4}[/tex]

When dividing fractions we flip the one we're dividing by and multiply:

[tex]\sf\dfrac{4}{7}\times\dfrac{4}{3}[/tex]

Multiply the numerators and denominators together:

[tex]\boxed{\sf\dfrac{16}{21}}[/tex]

So she sews 16/21 of a dress in one hour.

Hey there.

As we are looking for the perimeter of the polygon, we should understand the formula for each figure. For #2, we can clearly see that we have a square, which concludes that the perimeter for the figure is going to be 4S ('S' being the length of one side as all sides are equal).

Let's apply this to our problem.
P = 4S;
S = 6x + 3; set this up as an equation.

P = 4(6x + 3); apply the distributive property to the right side of the equation.
P = 4(6x) + 4(3);
P = 24x + 12

As we can see above, the perimeter of the square in problem #2 is going to be 24x + 12.

what is yhe best approximation of the value of w?
A) 1.4 cm
B) 4.0 cm
C) 6.0 cm
D) 7.3 cm

Answers

b 4.0 cm because if you think about it the one that says 3.3 cm is actually just slightly shorter than w so it has to be 4.0cm

Answer

B) 4.0 cm

Explanation

First, we can adapt the law of sines to the notation of our triangle:

[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]

Now, we can infer from our diagram that [tex]W=39[/tex], [tex]U=31[/tex], and [tex]u=3.3[/tex], so we can replace the values in our previous expression:

[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]

[tex]\frac{sin(39)}{w} =\frac{sin(31)}{3.3}[/tex]

Finally, we can solve for [tex]w[/tex]:

[tex]\frac{3.3sin(39)}{w} =sin(31)[/tex]

[tex]3.3sin(39)=wsin(31)[/tex]

[tex]\frac{3.3sin(39)}{sin(31)} =w[/tex]

[tex]w=\frac{3.3sin(39)}{sin(31)}[/tex]

[tex]w=4.03224[/tex]

Which rounds to [tex]w=4.0[/tex]

We can conclude that the best approximation of w is 4.0 cm

In ABC what is the measure of C

Answers

C = 36

To solve this equation, you know what each angle is equal to, and all triangles add to equal 180 degrees, so you can set it up like so:

6x + 2x + 2x = 180 Then combine all the x's and simplify by dividing.

Answer:

36 °

Step-by-step explanation:

Hello

In geometry an interior angle or an internal angle is an angle formed by two sides of a polygon that sharing a common end is contained within the polygon, and the sum of these angles is given by

sum=(n-2)*180°

where n is the number of sides of the polygon,in our case n= 3 (a triangle)

Step 1

find the sum o internal angles

sum=(3-2)*108°

sum=1*180°

(1)sum=180°

step 2

find x

now, according to the graph the sum of internal angles is

sum(graph)=6x+2x+2x

(2)sum=10x

(1) must be equal to (2)

180°=10x

isolating x

x=18

Step 3

find C

by the graph ,we know

C=2x

and x=18

replacing

C=2(18)

C=36°

a 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building. what angle does the ladder make with the ground?

Answers

66.42° you can just do 66.4°

The ladder makes an angle of 63.43 degrees with the ground.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building

We need to find the angle which the ladder make with the ground.

tan(x) = opposite side / adjacent side

In this case, the opposite side is the height of the building, which is 20 feet.

The adjacent side is the distance from the wall to the base of the ladder, which is 8 feet.

Plugging in the values:

tan(x) = 20 / 8

x=tan⁻¹(20/8)

x=63.43 degrees

x is the angle

Hence, the ladder makes an angle of 63.43 degrees with the ground.
