I need help on question a and b. please help me asap?!?!?

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:

6

Step-by-step explanation:

I think this is the answer but I'm not sure

[tex] {4x}^{2} + 3x - 10[/tex]

1. Use foil method.

[tex] {4x}^{2} 5x + 8x - 10[/tex]

2. Collect like terms.

[tex] {4x}^{2} + ( - 5x + 8x) - 10[/tex]

3. Simplify.

[tex] {4x}^{2} + 3x - 10[/tex]

Therefor, the answer is.

[tex] {4x}^{2} + 3x - 10[/tex]

Answer:

(x+2)(4x−5)=4x2+3x−10.

Step-by-step explanation:

 multiply (x+2)(4x−5)

using FOIL.

((x)+(2))((4x)+((−1)5))=(x)⋅(4x)+(x)⋅((−1)5)+(2)⋅(4x)+(2)⋅((−1)5)=

=(4x2)+(−5x)+(8x)+(−10)=

=4x2+3x−10

11=x+5 so 5+ what = 11 so, 6

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

meh not good at this

Explanation:

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:

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:

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.

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
