Answer:

It is a polygon, hexagon.

Step-by-step explanation:

Types of polygons include: Triangle, quadrilateral, Pentagon, hexagon, heptagon, octagon, nonagon, and decagon. a hexagon has 6 sides this has 8 so it isn't a hexagon but it can be a decagon so it's the second answer.

it is a polygon and it would be a decagon since there are 10 sides

The number line is a graph of... a. real numbers b. integers c. rational numbers

kap26 [50]

Integers

An integer is a whole number that is not a fraction

Whereas real numbers include fractions and so do rational numbers.

Rational numbers include terminating decimals and fractions. Meaning, they have an end number.

Pi for instance is an irrational number because it never ends

Sin x = cos x = tan x =

madreJ [45]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

so Sin(x) = d/f

Cos(x) = e/f

Tan(x) = d/e

got it? :)

Suppose that Jamal can choose to get home from work by taxi or bus. When he chooses to get home by taxi, he arrives home after 7

qwelly [4]

Answer:

0.55

Step-by-step explanation:

There are four things you need to keep in mind,and the question is too easy to solve , so following are those four things

1)Jamal travelling by Taxi before 7 PM

It is given that Jamal uses the bus for 70 percent of the time so he will use the taxi for (100-70)%=30% of the time.

and also it is given that he arrives home by taxi after 7 PM , 15% of the time so he will arrive home by taxi before 7 PM ,(100-15)=85% of the time,

so by multiplication law of probability , the probability that Jamal will arrive by taxi before 7 PM =0.30*0.85=.255

2)Jamal travelling by Taxi after 7 PM

Similarly by considering the above situations as described in first part,

the probability that Jamal will arrive by taxi after 7 PM=0.30*0.15=.045

3) Jamal travelling by Bus before 7 PM

Now considering the case of the bus, it is given that Jamal arrives home after 7 PM 8 percent of the time. so for before 7 PM it will be 100-8= 92%

Similarly the probability that Jamal will arrive by bus before 7 PM=0.70*0.92=.644

4) Jamal travelling by Bus after 7 PM

Similarly on the basis of above explanation we can easily say that the probability that Jamal will arrive by bus after 7 PM=0.70*.08=.056

so, the probability that Jamal chose to get home from work by bus, given that he arrived home after 7 pm= $=\frac{Jamal travelling by bus after 7 PM}{(Jamal travelling by taxi after 7 PM +Jamal travelling by bus after 7 PM}$

$=\frac{0.056}{0.056+0.045}$

$=\frac{0.056}{0.101} \\=0.554$

Angelo brought apples and bananas at the fruit stand. He bought 20 pieces of fruit and spent $11.50 apples cost $.50 and bananas

Jlenok [28]

Angelo bought 14 apples and 6 bananas

Solution:

Let "a" be the number of apples bought

Let "b" be the number of bananas bought

Cost of 1 apple = $ 0.50

Cost of 1 banana = $ 0.75

He bought 20 pieces of fruit. Therefore,

number of apples bought + number of bananas bought = 20

a + b = 20 -------- eqn 1

He spent $ 11.50. Therefore, we frame a equation as:

number of apples x Cost of 1 apple + number of bananas x Cost of 1 banana = 11.50

$a \times 0.50 + b \times 0.75 = 11.50$

0.50a + 0.75b = 11.50 ------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

a = 20 - b ------ eqn 3

Substitute eqn 3 in eqn 2

0.50(20 - b) + 0.75b = 11.50

10 - 0.5b + 0.75b = 11.50

0.25b = 11.50 - 10

0.25b = 1.5

Divide both sides of equation by 0.25

Substitute b = 6 in eqn 3

a = 20 - 6

Thus he bought 14 apples and 6 bananas
