The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

<h3>What is the measure of the missing interior angle in a heptagon?</h3>

Heptagons are polygons with seven sides, seven vertices, seven <em>interior</em> angles and seven <em>central</em> angles. Herein we know the value of the sum of six interior angles and we need to know the measure of the seventh <em>interior</em> angle. We can determine the measure of the seven interior angles by using the following expression:

θ = (n - 2) · 180°, where n is the number of sides of the polygon. (1)

If we know that n = 7, then sum of the internal angles in the heptagon is:

θ = (7 - 2) · 180°

θ = 900°

And the measure of the final interior angle is found by subtraction:

θ₇ = 900° - 776°

θ₇ = 124°

The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

The height, h, in feet of a gold ball above the ground after being hit into the air is given by the equation. H=-16t2+64t, where

stiv31 [10]

Answer:

4 seconds

Step-by-step explanation:

Given : $H = -16t^{2} +64t$

To Find: How many seconds does it take for the golf ball to hit the ground?

Solution :

Since we are given an equation : $H = -16t^{2} +64t$

Where H denotes height

t denotes the number of seconds elapsed since the ball was hit.

When he golf ball to hit the ground at that time the height becomes 0

So, put H = 0 in the equation

$H = - 16t^{2} +64t$

$0 = - 16t^{2} +64t$

$16t^{2} = 64t$

$16t = 64$

$t =\frac{64}{16}$

$t =4$

Thus it take 4 seconds for the golf ball to hit the ground

2x^2 + 3x - 12 when x = 5 help pls

cluponka [151]

$\huge\textsf{Hey there!}$

$\mathsf{2x^2 + 3x - 12}$

$\mathsf{= 2(5)^2 + 3(5) - 12}$

$\mathsf{5^2}$

$\mathsf{= 5 \times 5}$

$\mathsf{\bf = 25}$

$\mathsf{2(25) + 3(5) - 12}$

$\mathsf{2(25)}$

$\mathsf{= \bf 50}$

$\mathsf{3(5)}$

$\mathsf{= \bf 15}$

$\mathsf{= 50 + 15 - 12}$

$\mathsf{50 + 15}$

$\mathsf{= \bf 65}$

65 - 12

$\mathsf{= \bf 53}$

$\boxed{\boxed{\huge\textsf{Answer: \bf 53}}}\huge\checkmark$

The product of 1.3x10^-4 and a number n results in 2.6x10^12. What idle the value of n

Mademuasel [1]

1.3 x 10^-4 * n = <span>2.6 x 10^12
n = </span>2.6 x 10^12 / 1.3 x 10^-4
n = (2.6 / 1.3) x 10^16
n = 2 x 10^16

Answer
Idle the value of n = 2 x 10^16

Please solve with working out <br> simultaneous equations<br> 3x+2y=12<br> 2x+2y=10

Novay_Z [31]

Here, 3x + 2y = 12
2x + 2y = 10

Subtract 2nd from 1st equation,
x = 2

Now, substitute in 2nd,
2(2) + 2y = 10
2y = 10 - 4
y = 6/2
y = 3

In short, Your Answer would be: (2, 3)

Hope this helps!
