Please help im confused on the last question on my warm up!

Answer:

AC ≈ 5.5

Step-by-step explanation:

Angle bisector theorem states that "angle bisector of an angle divides the opposite side into two segments which are proportional to the other two sides of the triangle."

By applying this theorem in the given ΔABC,

AD is the angle bisector of ∠CAB which divides the opposite side of the angle into two segments BD and CD.

Therefore, [tex]\frac{AB}{BD}=\frac{AC}{CD}[/tex]

[tex]\frac{5.1}{4}=\frac{AC}{4.3}[/tex]

[tex]AC=\frac{5.1\times 4.3}{4}[/tex]

AC = 5.4825

AC ≈ 5.5 units

Answer:

800 cm squared

Step-by-step explanation:

10 x 15 x 4 = 600 + 10 x 10 x 2 = 200

600 + 200 = 800

Answer:

D

Step-by-step explanation:

With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.

A is incorrect as it is possible to land heads on any flip.

B is incorrect as there is always a possibility of landing tails on every flip.

C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely.

Hence D is the answer.

Answer:

4.189 radians

Step-by-step explanation:

Given data

θ=240 degrees

Let us convert from  degrees to radians

Angle in Radian= Angle in degree* π/180

Substitute

Angle in Radian= 240* π/180

Angle in Radian= 4* π/3

Angle in Radian= 4* 3.142/3

Angle in Radian=12.568/3

Angle in Radian=4.189 radians

Answer:

193.69

Step-by-step explanation:

Answer:

x = -180

Step-by-step explanation:

0 = 0.65x + 117

-117 = 65x/100

cross-multiply to solve for 'x':

65x = -11700

x = -11700/65

x = -180

Answer:

Using the "AC Method" I got (w - 2) (w + 9)

Step-by-step explanation:

Answer:

(w−2)(w+ 9)

Step-by-step explanation:

Grouping

Step 1:

Use the sum-product pattern

w²  + 7 − 18

w² + 9 − 2 −18

Step 2:

Common factor from the two pairs

w²+ 9 − 2 − 18w

( w+ 9) − 2( w+ 9)

Step 3:

Rewrite in factored form

(w + 9) − 2( w+ 9)

(w−2)(w+9)

Answer:

E) 37

Step-by-step explanation:

The total measurement for the angle ABC is 90 as it is a right angle.

Add your known angles together and substract from 90 to get your unknown.

90 - 21 - 32 = 37

Answer:

E. Subtract 21 and 32 from 90, x=37

Step-by-step explanation:

Since there are 90 degrees in a right angle, we can find the missing angle by adding the two angles we have together and then subtracting the sum from 90.

Answer:

Amount of water in each balloon = 300 milliliter

Step-by-step explanation:

Given:

Amount of water used in balloon = 6 liter

Number of water balloon  = 20 balloon

Find:

Amount of water in each balloon

Computation:

Amount of water used in balloon = 6 x 1000

Amount of water used in balloon = 6,000 milliliter

Amount of water in each balloon = Amount of water used in balloon / Number of water balloon

Amount of water in each balloon = 6,000 / 20

Amount of water in each balloon = 300 milliliter

Answer:

12 cm^2

Step-by-step explanation:

Here the base and height of a triangle are given.  To find the area, we use the formula A = (1/2)(base)(height), which here is

A = (1/2)(8 cm)(3 cm) = 12 cm^2

The effect on the parabola y = x^2 - 1 when it is changed to y = x^2 + 6 is a translation of 7 units upwards.

First let's do an introduction, for any function f(x), we can define a vertical translation of N units as:

g(x) =f(x) + N

Where if N > 0, the translation is upwards, and if N < 0, the translation is downwards.

In this case, we start with the parabola:

y = f(x) = x^2 - 1

Now we know that the transformed function is:

y = g(x) = x^2 + 6

Now, notice that if we apply a translation upwards of 7 units of the original function we will get:

y = f(x) = x^2 - 1 + 7 = x^2 + 6

We got the transformed function.

Then the effect on the parabola is a translation of 7 units upwards.

Answer:

La respuesta esta abajo

Step-by-step explanation:

Un triángulo es un polígono con tres lados y tres ángulos.

Se dice que dos triángulos son proporcionales si la razón de sus lados correspondientes está en la misma proporción.

de la pregunta, el lado AB es proporcional a DF, AC es proporcional a DE y BC es proporcional a FE

Por lo tanto, dado que ambos triángulos son proporcionales, entonces:

DE / DF = AC / AB

Answer:

(1/2, 19/4)

Step-by-step explanation:

So the formula is y=-b/2a.

a= 1

b= -1

Plug in the values to get x=1/2.

you then plug in 1/2 to get the y

you end up with 19/4.

Your vertex ends up as (1/2, 19/4).

Answer:

[tex] \displaystyle PW = \underline{ \quad18 \quad}[/tex]

Step-by-step explanation:

by tangent property we acquire:

[tex] \displaystyle 3x - 6 = x + 10[/tex]

add 6 to both sides:

[tex] \displaystyle 3x= x + 16[/tex]

cancel x from both sides:

[tex] \displaystyle 2x= 16[/tex]

divide both sides by 2:

[tex] \displaystyle x= 8[/tex]

so,

[tex] \displaystyle PW = 3x - 6[/tex]

plug in the got value of x:

[tex] \displaystyle PW = 3.8 - 6[/tex]

simplify multiplication:

[tex] \displaystyle PW = 24- 6[/tex]

simplify Substraction:

[tex] \displaystyle PW =18[/tex]

hence, The measure of PW is 18 unit

[tex] = ( - \dfrac{1}{2} ) \times ( - \dfrac{1}{2} ) \times ( - \dfrac{1}{2} ) \\ = ( - \frac{1}{2} ) ^{3} [/tex]

Answer: [tex]\dfrac{2}{9}[/tex]

Step-by-step explanation:

Given

The spinner has 6 equal sections A, B, C, D, E, and F

The two events occurred one after the other. So, the probability is the product of the probabilities of each event.

There are two consonants in the given 6 letter

The probability of landing over a consonant  is

[tex]P_1=\dfrac{2}{6}[/tex]

The number greater than 2 in a cube are 3,4,5,6

So, probability corresponding to it

[tex]P_2=\dfrac{4}{6}[/tex]

So, the required probability is

[tex]\Rightarrow P=P_1\times P_2\\\Rightarrow P=\dfrac{2}{6}\times \dfrac{4}{6}\\\\\Rightarrow P=\dfrac{8}{36}\\\\\Rightarrow P=\dfrac{2}{9}[/tex]
