Answer: 4.8

Step-by-step explanation:0.6*5+0.6*1 1/2*2

Answer:

14/33

Step-by-step explanation:

Okay so first of all, we want to find the probability of picking that first purple marble. There are 8 purple marbles you can chose out of a possible 12 marbles, so the probability is 8/12, or 2/3.

Next, find the probability of finding the second purple marble. Since you took out one purple marble already, there are 7 purple marbles you could chose out of a possible 11 marbles, so the probability is 7/11.

To find out the probability of both of these events happening, you multiply these probabilities:

[tex]\frac{2}{3} * \frac{7}{11}\\\frac{2*7}{3*11} \\\frac{14}{33}[/tex]

Step-by-step explanation:

Surface area is the area of all sides added

Volume is LengthxWidthxHeight divided by three

Answer:

12 feet

Step-by-step explanation:

Given: length = 15 feet, width = L x 80%

Unknown: width = ?

 width = L x 80%

        w = (15ft) x 80%     or (15ft) x .80

        w = 12 ft

Answer:

Formula of rectangle :-

l ×b

80/100 × 15 ×b

8/10 × 15 ×b

80/100 × 15 =b

8/10 ×15 =b

4/5 × 15 =b

4 × 3 = b

b = 12feet

b = 12 feet

Answer:

x = 142°

Step-by-step explanation:

Since angle x and the 38° angle are supplementary angles, we know that the following is true...

x + 38° = 180°

x = 180° - 38°

x = 142°

Actually Welcome to the Concept of the quadratic equations.

Since, as the question told,

=>

[tex] \frac{ {x}^{2} }{3} - 3 = 0[/tex]

hence now solving we get as,

[tex] \frac{ {x}^{2} }{3 } = 3 [/tex]

now, we get as,

[tex] {x}^{2} = 9[/tex]

now, then

[tex] \sqrt{ {x}^{2} } = \sqrt{9} [/tex]

so finally, positive value of x is 3

Step-by-step explanation:

it does not matter which side you put the eight.

Answer:

that is the first one and the last one.

Step-by-step explanation:

we have to check which ones have negative eight as y values so that is the first one and the last one.

if my answer helps please mark as brainliest.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

The ordered pair that is a solution to y = -8 are:

(5, -8) and (-7, -8).

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

y = -8

We have the ordered pairs:

(5, -8), (-8, 9), (0, 6), and (-7, -8).

Now,

The solutions to y = -8.

y = -8 is a constant function.

This means,

Any value of x will give -8.

Now,

The ordered pair that is a solution to y = -8 are:

(5, -8) and (-7, -8).

Step-by-step explanation:

you can use fraction strips by using them 3/4 and 6/8 because they are equivalent  and that's just life :)

3/4 and 6/8 are equivalent numbers/fractions

The fractions are given as:

[tex]\frac 34[/tex] and [tex]\frac 68[/tex]

To model 3/4 using number lines, we do the following steps

To model 6/8 using number lines, we do the following steps

When both points are compared, then we find out that:

[tex]\frac 34 \equiv \frac 68[/tex]

Hence, 3/4 and 6/8 are equivalent

77 pots

Step-by-step explanation:

To find how many pots he washes in 1 3/4 hours, multiply 44 by 1.75, since

3/4 = 0.75.

44(1.75)

= 77

So, Randy can wash 77 pots in 1 3/4 hours

Answer:

77

Step-by-step explanation:

He washes 11 every quarter of an hour, so just add 33 to 44

Answer:

When we have  a set of N numbers like:

{x₁, x₂, ..., xₙ}

The mean of the set is:

M = (x₁ + x₂ + ... + xₙ)/N

In this case, we have the set:

{250, 280, 265, 245, 270, 255, 290}

So we have a set of 7 elements.

The mean of this set will be:

M = (250 + 280 + 265 + 245 + 270 + 255 + 290)/7 = 1855/7 = 265

So the mean number of stomata per mm of leaf surface is 265.
