The answer to this would actually be B.

50 is the minimum because it is the first number and 80 is the maximum because its the last number. All of the answer choices have different answers for maximum and minimum. So the only answer to prove me correct is answer choice B.

The measures of the angles of a quadrilateral are in the

bearhunter [10]

Answer:

140

Step-by-step explanation:

Consider a square for just a second. It has 4 angles each of 90 degrees. The total number of degrees in a square is 4 * 90 = 360.

It should be at least an appeal to your intuition to say that a quadrilateral has a total of 360 degrees.

Therefore the ratio you have been given must have 4 angles that add to 360.

2x + 3x + 6x + 7x = 360

18x =360

x = 20

So the 4 angles are

2* 20 = 40

3*20 = 60

6*20 = 120

7*20 = 140

Total 360

The largest angle is 140

Solve Triangle DEF. - Math

Brrunno [24]

Answer:

$p = 52.942259755149776$

Step-by-step explanation:

This is basic trigonometry.

$\cos(39) = \frac{e}{22}$

$e = \cos(39) \times 22$

$\sin(39) = \frac{d}{22}$

$d = \sin(39) \times 22$

And finally perimeter (p):

$p = 22 + e+ d$

Little Johnny is fleeing from a horde of zombies. He is 4000 feet from a safe zone where a gate will be closed in 3 minutes. If

Free_Kalibri [48]

Answer:

Johnny will be able to reach the safe zone before the gate is closed.

Step-by-step explanation:

Given that:

Distance of Little Johnny from safe zone = 4000 feet

Time = 3 minutes

Speed = 22 mph

To find:

Will Johnny be able to reach the safe zone ?

Solution:

Johnny can only be safe if he can travel 4000 feet in 3 minutes with the given speed.

Let us try to find out, the distance that he can travel in 3 minutes at speed of 22 mph.

Let us have a look at the formula of distance traveled:

$Distance = Speed \times Time$

Time = 3 minutes = $\frac{3}{60}$ hrs

Speed = 22 mph

$Distance = 22 \times \frac{3}{60}\\\Rightarrow Distance = \dfrac{22}{20}\ miles \\\Rightarrow Distance = 1.1\ miles$

We know that 1 mile = 5280 feet

Therefore 1.1 miles = 5280 $\times$ 1.1 feet = 5808 feet

Distance traveled by Little Johnny is greater than 4000 feet.

Therefore Johnny will be able to reach the safe zone before the gate is closed.

(2,?) is on the line 4x – 5y = -7. Find the other half of the coordinate.

Cerrena [4.2K]

$(x,y)=(2,?) \\ x=2 \\ y=? \\ \\
4x-5y=-7 \\
4 \times 2-5y=-7 \\
8-5y=-7 \\
-5y=-7-8 \\
-5y=-15 \\
y=\frac{-15}{-5} \\
y=3$

The coordinate is (2,3).
