The measures of the acute angles of a right triangle are in the ratio 5:7

Answer: z = -3

Step-by-step explanation:

2/3z = -2

2z = -6 (Multiply both sides by 3)

z = -3 (Divide both sides by 2)

Answer:

The correct options are;

A. [tex]-\dfrac{8}{3} \ miles[/tex]

D.  [tex]2\dfrac{2}{3} \ mile[/tex] below sea level

Step-by-step explanation:

The given parameters are;

The distance Sasha travels down before a stop = -2/3 mile

The level at which Sasha starts to hike into the canyon = Sea level

Therefore, we have;

Her elevation at the fourth rest station = 4 × -2/3 mile = -8/3 miles

Therefore, we have;

-8/3 mile = [tex]2\dfrac{2}{3} \ mile[/tex] below sea level

Therefore, the correct options are;

-8/3 mile and  [tex]2\dfrac{2}{3} \ mile[/tex] below sea level.

Answer:

Step-by-step explanation:

8p < -3

You must isolate P

In order to do this, you need to get rid of anything on that side.

P is being multiplied by 8, so you must do the inverse in order to get rid of it.

The opposite of multiplying is dividing, so divide BOTH sides by 8.

8p / 8 < -3 / 8

You are left with:

p < -3 / 8

That is the answer

Answer:

b. 144 degrees

Step-by-step explanation:

(n-2)(180)

10-2=8

8*180=1440

The polygon has 10 sides so divide by 10

1440/10= 144

Answer: 140

Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D

Answer: f(-4) = 17

Step-by-step explanation: Substitute (-4) for x.

Answer: x = -0.2651 and y = -0.9759

Step-by-step explanation:

Solution by substitution method

8x+5y= -7

-7x+6y= -4 = 7x-6y=4

Suppose,

8x+5y=-7→(1)

7x-6y=4→(2)

Taking equation (1), we have

8x+5y= -7

⇒8x= -5y -7

⇒x= -5y-7 / 8 →(3)

Putting x= -5y-7 / 8

in equation (2), we get 7x-6y=4

7(-5y-7/8)-6y=4

⇒-35y-49-48y=32

⇒-83y-49=32

⇒-83y=32+49

⇒-83y=81

⇒y= 81 / -83

⇒y= -0.9759→(4)

Now, Putting y= -0.9759 in equation (3), we get

x= -5y-7

x= -5(-0.9759)-7/8

⇒x= 4.8795-7/8

⇒x= -2.1205/8

⇒x= -0.2651

∴x= -0.2651 and y = -0.9759

Answer:

The giraffe will be 2 inches

Step-by-step explanation:

If we know that if the scale is 1/2 inch to 5 feet we simply just have to divide the height of the giraffe by 5 feet and then multiply it by 1/2 inches. So we do...

20feet / 5 feet x 1/2 inches = 4 x 1/2inches = 2 inches

Answer: REMEMBER (X, Y)

x(4 1/4, 0)

y(0, -5 2)

Step-by-step explanation:

Find the x-intercept

To find x intercept subtract y equals 0

4 x - 3 × 0 = 17

Any equation multiplied by  0 equals 0

4x - 0 = 17

When adding or subtracting zero quality does not change

4x = 17

Divide both sides of the equation by 4

x = 17/4

Solution

X = 17/4

Alternate form

X = 4 1 / 4, x = 4.25

Find y-intercept

To find y intercepts subtract x equals 0

4 × 0 - 3y = 17

Solve the equation for y

Y = -17 / 3

Solution

y = -17 / 3

Alternate form

y = -5 2 / 3, y = -5.6

Complete question :

Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. The box contains 72 chocolates altogether. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white?

Answer:

7 / 9

Step-by-step explanation:

Calculate the number of each type of chocolate :

Milk : plain : white = 4 : 3 : 2

Total ratio = (4 +3 +2) = 9

Milk = (4/9) * 72 = 32

Plain = (3/9) * 72 = 24

White = (2/9) * 72 = 16

Probability of picking a chocolate that is not white :

Number of non-white :

(plain + milk) = (24 + 32) = 56

Probability = (required outcome / Total possible outcomes)

P(not white chocolate) = (number of non-white / total number of chocolates)

= 56 / 72

= 7 / 9

Answer:

x = 20

Step-by-step explanation:

Here, we want to get the value of x

To get the value of x, we need to know the kind of relationship that exists between the two given angles

Both angles lie on a straight line and that means they are supplementary

What this mean is that they add up to 180

(5x-7) + (3x + 27) = 180

5x -7 + 3x + 27 = 180

5x + 3x -7 + 27 = 180

8x + 20 = 180

8x = 180-20

8x = 160

x = 160/8

x = 20
