Answer:

Step-by-step explanation:

Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring.

Answer:

1 ) Adjacent angles,

2 ) See solution below

Step-by-step explanation:

Question 1. Provided ∠ 1 and ∠ 1 are near one another, they can be referred to as adjacent ∠s;

Solution; Adjacent angles

Question 2.

Angles 5, and 6 are consecutively near one another, and thus are adjacent angles,

Angles 5 and 9 are supplementary knowing that they lie on a straight angle, so that they can be best named a linear pair, provided there are only two of these angles,

Angles 5 and 8 are opposite to one another so that they are ≅, thus should be names as vertical angles

Solution;

Angle | Adjacent Angles | Linear Pair | Vertical angles

∠ 5, 6 |        Check!          |                    |                        

∠ 5, 9 |                              |    Check!    |

∠ 5, 8 |                              |                    |        Check!

b)

[tex]x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}[/tex]

Step-by-step explanation:

Step(i):-

Given quadratic equation ax² + bx + c = 0

step(ii):-

ax² + bx = -c

Step(iii):-

Dividing 'a' on both sides , we get

[tex]\frac{ax^{2} +bx }{a} = \frac{-c}{a}[/tex]

[tex]x^{2} + \frac{bx}{a} = \frac{-c}{a}[/tex]

Step(iv):-

Adding  [tex](\frac{b}{2 a} )^{2}[/tex] on both sides , we get

[tex]x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}[/tex]

Answer:

35 ÷ 5 = g

Step-by-step explanation:

First, you snatch her/his money to do math, then you take the $35 and look the the thing that tells you how much games cost then do 35 ÷ 5 but since you cant solve it just put 35 ÷ 5 = g , and last but not least you take Kendle's money because no lazer tag during a pandemic and run home before you get yelled at because you were at a lazer tag place and took someones money.

Answer:

35/5=g

Step-by-step explanation:

it's pretty simple! she has 35$ but each game is 5$ so 35 over 5 is g. and g= 7 hope this helped

Answer:

8/25

Step-by-step explanation:

We do this by multiplying the top first, and we get 32.

We then multiply the bottom, and get 100.

You might think the answer is 32/100.

Well, kind of! We need to simplify!

we divide the top and bottom by four to get our answer, 8/25.

Answer:

The answer is 40

Step-by-step explanation:

The reason for this is because. . .

(-1,-4) , (3,6)

so you have count from -1 to 3 and u will get 4, because if you can put (-1,-4) and (3,6) on a graph. If you did that then u must count horizantolly from -1 to 3 since they are on the x-axis. In the end you will get 4 since 3 minus -1 is 4. Also if your counting horizantally then that's ur width.

width = 4

To find the length, it is very simple. Subrtract 6 from -4 and you will get 10. And since the y-axis is being counted vertically, that is your length.

length = 10

To find the area, u have to do width times length so in this case you have to do 4 time 10 and you will get 40.

area = 40

Answer:

6.95 cm

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the height )

Here A = 34.75 and h = 5, thus

34.75 = 5b ( divide both sides by 5 )

b = 6.95 cm

Answer:

-x² + x - 1

Step-by-step explanation:

(f/g)(x) means that you have to divide f(x) by g(x).

[tex]\frac{x^4-x^3+x^2}{-x^2}\\ -x^2+x-1[/tex]

When dividing exponents with the same base, you have to subtract the exponents to find the quotient.

When dividing with negatives, you have to switch the sign of the other number.

Answer:

The car has an initial speed of 35 units and is slowing down by 4 units per second.

Step-by-step explanation:

The changing speed of a car is modeled by the function :

[tex]s(t)=-4t+35[/tex]

t is time in seconds

Initial speed means at t = 0

s(0) = 35 units

Here the change in speed is negative, it means that the car is slowing down by this rate.

So, the correct answer is : The car has an initial speed of 35 units and is slowing down by 4 units per second.

Answer:

y=18.51

Step-by-step explanation:

First we must figure out the value of "x". We can do that in the first equation. To find the value of "x" you divide both sides by 20. That will give you the value of "x" which is 2.7. With this information, you can plug in that value into the second equation to get the value of "y". 2(2.7)(y)=100. Multiply 2 and 2.7 to get 5.4. Then divide 5.4 from both sides to get the value of "y" which is around 18.51. I hope this helped.

Let x represent distance between the base of the tower and the fire.

We have been given that a forest forest ranger is on a lookout tower in a forest. His observation tower is 214.7 feet above the  ground when he spots an illegal forest fire. The angle of elevation from the fire to the top of  the lookout is 78 degrees.

To find the distance between the base of the tower and the fire, we will use trigonometric ratio.

First of all, we will draw a right triangle using our given information as shown in the attached image.

We can see that x is adjacent side and 214.7 is opposite side to angle 78 of degrees.

[tex]\tan=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

[tex]\tan(78^{\circ})=\frac{214.7}{x}[/tex]

[tex]x=\frac{214.7}{\tan(78^{\circ})}[/tex]

[tex]x=\frac{214.7}{4.704630109478}[/tex]

[tex]x=45.63589379[/tex]

Upon rounding to nearest tenth, we will get:

[tex]x\approx 45.6[/tex]

Therefore, the distance between the base of the tower and the fire is approximately 45.6 feet.

Answer:

C

Step-by-step explanation:

i may be wrong sorry

60 total fourth graders and 43 are girls. To find the number of boys, subtract.

60 - 43 = 17 boys

If 5 girls were absent, subtract.

43 - 5 = 38 girls present

If 4 boys were absent, subtract.

17 - 4 = 13 boys present

Therefore, there were 13 boys present.

Best of Luck!

Answer:

13 boys were present

Step-by-step explanation:

→ In total there is 60 fourth graders at the Small Tree School.

→ 43 of them are girls and this information is given to us which means that there is 17 boys because 60 - 43 = 17

→ We want to know know how many boys were at the school on Friday considering that 5 fourth grade girls and 4 fourth grade boys were absent

→ We know that there is a total of 17 boys and 4 fourth grade boys were absent so 17 - 4 will give us the number of boys that were present  on Friday so 17 - 4 = 13. 13 boys were present considering 5 fourth grade girls and 4 fourth grade boys were absent

Answer:

73

Step-by-step explanation:

I think you mean the discriminant.

You calculate it by using b^2 - 4ac

a = 2

b = 7

c = -3

So it would be 49 - 4 * 2 * -3

49 + 24

73
