How do you estimate 10.43
Veronika [31]

Answer:

Step-by-step explanation:

Given 10.43, you can 'estimate' it only by rounding off:

10.43 to the nearest tenth is 10.4.

10.43 to the nearest whole number is 10; we drop the fraction 0.43.

How many times does a dragonfly's wing beat per minute
marshall27 [118]
<span>A dragonfly beats its wings about 30 times a second. This is necessary to allow the insect to keep itself airborne, due to the relative weight of its body. Luckily, dragonflies have two sets of wings, or they would have to work even harder to stay up in the air.</span>

Kristin graphed the locations of several places in her school on the coordinate plane shown below. Determine if each statement a
wel

Answer:

Step-by-step explanation:

1). Coordinates of Art → (1, -5).

   Coordinates of Library → (1, 9)

   Coordinates of Science → (-5, -5)

   Distance between Art and Library = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

                                                             = \sqrt{(1-1)^2+(9+5)^2}

                                                             = 14 units

   Distance between Art and Science = \sqrt{(1+5)^2+(-5+5)^2}

                                                               = 6 units

   Since 14 > 6,

   Art is closer to Science than Library.

   Answer is False.

2). Coordinates of Cafeteria → (-7, 9)

    True.

Evaluate (y - 9) + (3 + x), when y = 15 and x = 5​
svet-max [94.6K]

Answer:

14

Step-by-step explanation:

It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5​'.

So we'd put 15 in y's place. It'll look like this (15 - 9).

Then we'd put 5 in x's place. It'll look like this (3 + 5).

You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!

Thanks and a metal to who ever answers:) Cuban military invaded Eastern Mexico in a surprise attack. Cuba intends to gain territ
Aleksandr-060686 [28]
The United Nations has historically been the place to ask for aid and sometimes for mediation when one nation attacks another - as in Korea in 1950 or Kuwait in 1990. 

Most nations in North and South America are members of the Organization of American States the OAS, which is, among other things, a mutual defense treaty to support one another in the event of attack. 

I assume from your question that in this exercise you are imagining yourself to be the US President or his advisors. 

Responses in a case like this would be military, using naval and air forces to support Mexican military operations, perhaps including transport of US troops to Mexico to assist. Also, bombing strategic military stations in Cuba would weaken the Cuban military's ability to support its invasion.
