Answer:

The answer would be yes and no!! But, it would be no!

Step-by-step Explanation:

Yes: On Monday and Tuesday, those would be proportional because they are just counting by 60´s. 60 plus 60 would give you 120.

No: On Wednesday, this ¨person¨ traveled 360 miles in 3 hours. Now, you aren´t counting by 60´s anymore. Even though you started out counting by the 60´s, doesn´t mean you will finish like that.

60´s:

1 hour = 60 mi

2 hours = 120 mi

3 hours should be = 180 miles, not 360 Because:

360 mi would be equal to 6 hours. Do you see where I´m going with this?

Hope that helps you so you can put it in a mathematical way. Have a great day!!

If you get it wrong, plz notify me any way possible...... :)

Answer:

It's not proportional

Step-by-step explanation:

The first 2 days are proportional because, they travel at an increment of 60 miles an hour.

But, on the third day, it is not proportional because they travel at an increment of 90 miles an hour.

360 / 4 = 90

120 / 2 = 60

60 / 1 = 60

so, I need to just find the missing length, if you can, please explain the pythagorean theorem to find the missing side. I don't

ANTONII [103]

The surface area of the triangular prism is 828 in².

Solution:

Let the missing length of the triangle be x.

Using Pythagoras theorem,

In right triangle, square of the hypotenuse is equal to the sum of the squares of other two sides.

$12^2+x^2=15^2$

$144+x^2=225$

Subtract 144 on both sides of the equation.

$x^2=225-144$

$x^2=81$

Taking square root on both sides, we get

x = 9

The missing length of the triangle is 9 in.

Area of the front triangle = $\frac{1}{2}\times 12\times 9$

= 54 in²

Area of the back triangle = $\frac{1}{2}\times 12\times 9$

= 54 in²

Area of the sloping rectangle = 20 × 9

= 180 in²

Area of the back rectangle = 20 × 12

= 240 in²

Area of the base rectangle = 20 × 15

= 300 in²

Total area = 54 in² + 54 in² + 180 in² + 240 in² + 300 in²

= 828 in²

The surface area of the triangular prism is 828 in².

Imagine drawing a figure with the following conditions: A quadrilateral with at least two right angles. Is the figure described

Mrac [35]

Answer:

The figure is NOT unique.

Imagine the following quadrilaterals:

Rectangle

Square

We know that:

Both quadrilaterals have at least two right angles.

However, they are not unique because they depend on the lengths of their sides.

Step-by-step explanation:

To construct a quadrilateral uniquely, five measurements are required. A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given or if the lengths of its three sides and two diagonals are given.

Just given two angles we cannot construct a unique quadrilateral. There may be an infinite number of quadrilaterals having atleast two right angles

Examples:

All squares with varying sides

All trapezoids with two right angles

All rectangles with different dimensions

and so on.

Answer is

No.

the leungs sold a valuable painting for 55,000. this price is 1,000 more than twice the amount they originally paid for it. how

LekaFEV [45]

55,000-1000= 54,000
54,000/2= 27,000
The originally price was $27,000
