Given:

The dimensions of a box are 3ft, 3ft and 13 ft.

To find:

The length of the longest flagpole that could be shipped inside the box.

Solution:

We know that the length of longest flagpole that could be shipped inside the box is equal to the length of the diagonal.

[tex]Diagonal=\sqrt{l^2+b^2+h^2}[/tex]

Where, l is length, b is breadth and h is height.

[tex]Diagonal=\sqrt{(3)^2+(3)^2+(13)^2}[/tex]

[tex]Diagonal=\sqrt{9+9+169}[/tex]

[tex]Diagonal=\sqrt{187}[/tex]

[tex]Diagonal\approx 13.67[/tex]

Therefore, the longest flagpole that could be shipped is about 13.67 feet long.

What's the answer to 8m - 14=3m+46​

Answers

Answer:

Simplifying

8m + -14 = 3m + 46

Reorder the terms:

-14 + 8m = 3m + 46

Reorder the terms:

-14 + 8m = 46 + 3m

Solving

-14 + 8m = 46 + 3m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-3m' to each side of the equation.

-14 + 8m + -3m = 46 + 3m + -3m

Combine like terms: 8m + -3m = 5m

-14 + 5m = 46 + 3m + -3m

Combine like terms: 3m + -3m = 0

-14 + 5m = 46 + 0

-14 + 5m = 46

Add '14' to each side of the equation.

-14 + 14 + 5m = 46 + 14

Combine like terms: -14 + 14 = 0

0 + 5m = 46 + 14

5m = 46 + 14

Combine like terms: 46 + 14 = 60

5m = 60

Divide each side by '5'.

m = 12

Simplifying

m = 12

Answer:

m = 12

Step-by-step explanation:

We want to isolate "m" on one side of equation to see what it is equal to.

Step 1.

Add 14 to both sides of the equation to get 8m = 3m + 60

Step 2.

Subtract 3m from both sides to get 5m = 60

Step 3.

Divide both sides by 5 to get m = 12.

if this is true for the triangles then they are indeed right triangles

for figure 1...

[tex]6^2=36\\8^2=64\\36+64=100\\10^2=100\\100=100[/tex]

this is true therefore figure 1 is a right triangle

Chris pays a fee if the bank balance falls below $10 on the statement dae. Prior to the statement date her balance was -3.46. Then Chris made a deposit (d) in time so she does not have to pay the fee.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Balance prior to statement date = - 3.46

Minimum bank balance to avoid penalty = $10

The amount of deposit, d made in time in other to avoid penalty fee?

Minimum amount that most have been deposited, d :

Balance prior to statement + d ≥ minimum bank balance to avoid penalty

-3.46 + d ≥ 10

d ≥ 10 + 3.46

d ≥ 13.46

Hence, the minimum amount that must have been deposited to avoid penalty is 13.46

The graph of the equation is attached with the answer below. Showing the coordinates ( 0,10 ) and ( 5, 0 ).

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the equation of the line is y = 10 - 2x. When the graph is plotted for the equation y = 10 - 2x it cut the x-axis at the coordinate ( 5, 0 ) and cut the y-axis at the coordinate ( 0, 10).

The graph of the line y = 10 - 2x is attached with the answer below.

Hence to verify :

(82 * 9) + 7

738 + 7
