Answer:

65

Step-by-step explanation:

115-180=65 degrees

Answer:

68+47+x= 180

x=180-115

x=65

Answer:

a = 60km

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

a² + 32² = 68²

a² + 1024 = 4624

*subtract 1024 from both sides to isolate a² *

a² + 1024 - 1024 = 4624 - 1024

a² = 3600

*square root both sides to isolate a*

√(a²) = √3600

a = 60km

Answer:

a. 20

b. 25

Step-by-step explanation:

Let find the side lengths of the rectangle,

We can complete the square.

[tex] {x}^{2} + 4x - 21[/tex]

[tex] {x}^{2} + 4x = 21[/tex]

[tex] {x}^{2} + 4x + 4 = 25[/tex]

[tex](x + 2) {}^{2} = 25[/tex]

[tex](x + 2) = 5[/tex]

[tex]x = - 7[/tex]

or

[tex](x + 7)[/tex]

[tex]x = 3[/tex]

or

[tex](x - 3)[/tex]

This means the perimeter of is

2 times -7 equal 14

2 times 3 equal 6

14+6=20.

The side lengths of the square is equal so each side length will measure 5.

[tex] {5}^{2} = 25[/tex]

Answer:

Yes, that's an angle bisector.

You are correct in saying that this is a bisector.

Answer:

$197.28

Step-by-step explanation:

perimeter of a square = 4 x length

length = perimeter / 4 =  68/4 = 17 ft

Price of the first fence = perimeter x price per foot

68 x 1.37 = 93.16

Perimeter of the second fence = (17 + 2 ) x 4 = 76

total price  = sum of the price of the two fences

Price = 76 x 1.37 = 104.12

total price = 197.28

Answer:

x=-16

Step-by-step explanation:

from x=-3 to get to y=12 u need to multiply x=-3 by -4 to get to 12 so for y=64 u need to divide by -4 which equals x=-16

Answer:

x is (-16)

Answer:

B) (3,1)

Step-by-step explanation:

y = -2x + 7

y = 3x - 8

3x - 8 = -2x + 7

combine like terms:

5x = 15

divide both sides of the equation by 5:

x = 3

y = 3(3) - 8 = 1

Answer:

96

Step-by-step explanation:

Step-by-step explanation:

Answer:

B) -9/2 , 3/2

That's the correct answer

The midpoint of the given segment is (-9/2, 3/2), so the correct option is b.

For a segment whose endpoints are (a, b) and (c, d), the midpoint of that segment is given by the point:

( (a + c)/2, (b + d)/2).

In this case the endpoints are (-3, 4) and (-6, -1), using the above formula, we get that the midpoint is:

( (-3 - 6)/2, (4 - 1)/2) = (-9/2, 3/2)

We can see that the correct option is B.

Answer:

Let Kylie use the simple interest option

Step-by-step explanation:

Given data

Principal=  $5,000

I will advise Kylie to pay up the loan using the simple interest option, this is because the interest does not get to compound (pile-up) over time

But with the compounding interest option, the interest tends to increase exponentially

Answer:

28 cubs

Step-by-step explanation:

Since one and a half bear produces one and a half cub, then 6 bears will produce 6 cubs in one and a half days.

We need to find 7 days, though but we have the rate for six bears for 1.5 days which 6 bears one a half day.

What is the rate for a day?

6/1.5 =

6 bears produce 4 cubs a day.

Now just do 4 x 7

4 x 7 = 28

Therefore, 6 bears produce 28 cubs in 7 days.

Answer:

The displac ment between t = 1 and t = 4 is 272 feet

Step-by-step explanation:

To get the displacement of the ball, we first need to get the equation for the position of the ball with respect to time.

We can do this by differentiating the velocity equation given:

v(t) = -32t +96

integrating between the limits of t = 1 and t = 4, we have

[tex]s = \int\limits^4_1 {-32t +96} \, dt[/tex]

[tex]s(t) = -32t^2/2 +96t[/tex]

[tex]s =[ -16t^2 +96t] t = 4, t =1[/tex]

where t = 4.

s = 256 + (96) =352 feet

Where t = 1

s = 80

Displacement of the ball = 352 -80 = 272ft

The displac ment between t = 1 and t = 4 is 272 feet

Answer:4

Step-by-step explanation: 17 = 5y-3

Answer:

10

Step-by-step explanation:

Answer:

p = s + dgh

p - s = dgh

(p - s) / dg = h

Answer = h= p-s/dg

The formula that represents the height "h" in terms of p, s, d, and g is expressed as  (p - s)/dg

Given the formula for determining the pressure, p, exerted  on an object at a depth, h, below the surface of a  liquid expressed as p = s + dgh where:

s is the atmospheric  pressure,

d is the density of the liquid, and;

g is the  acceleration due to gravity

We are to make h the subject of the formula;

p = s + dgh

Subtract s from both sides

p - s = dgh

dgh = p - s

Divide both sides by dg

dgh/dg = (p - s)/dg

h =  (p - s)/dg

Hence the formula that represents the height "h" in terms of p, s, d, and g is expressed as (p - s)/dg

Answer:

[tex] slope(m) = \frac{3}{2} [/tex]

Step-by-step explanation:

Slope (m) = change in y / change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use any two pairs of values to find the slope. Thus, let's use (-14, 3) and (-12, 6):

Where,

[tex] (-14, 3) = (x_1, y_1) [/tex]

[tex] (-12, 6) = (x_2, y_2) [/tex]

Plug in the values

[tex] m = \frac{6 - 3}{-12 -(-14)} [/tex]

[tex] m = \frac{3}{2} [/tex]
