Answer:

4a^2 + 9a + 10

Step-by-step explanation:

First we distribute

-4a^2 + (−6a) + (5)(3a) + (5)(2)

-4a^2 - 6a + 15a + 10

Then we combine like terms

4a^2 has no like terms, so it cannot be added onto anything else.

We add -6a to 15a

15a - 6a = 9a

4a^2 + 9a + 10

Answer:

Simplifying

(6a + -8)(4a2) = 0

Reorder the terms:

(-8 + 6a)(4a2) = 0

Remove parenthesis around (4a2)

(-8 + 6a) * 4a2 = 0

Reorder the terms for easier multiplication:

4a2(-8 + 6a) = 0

(-8 * 4a2 + 6a * 4a2) = 0

(-32a2 + 24a3) = 0

Solving

-32a2 + 24a3 = 0

Solving for variable 'a'.

Factor out the Greatest Common Factor (GCF), '8a2'.

8a2(-4 + 3a) = 0

Ignore the factor 8.

Subproblem 1

Set the factor 'a2' equal to zero and attempt to solve:

Simplifying

a2 = 0

Solving

a2 = 0

Move all terms containing a to the left, all other terms to the right.

Simplifying

a2 = 0

Take the square root of each side:

a = {0}

Subproblem 2

Set the factor '(-4 + 3a)' equal to zero and attempt to solve:

Simplifying

-4 + 3a = 0

Solving

-4 + 3a = 0

Move all terms containing a to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 3a = 0 + 4

Combine like terms: -4 + 4 = 0

0 + 3a = 0 + 4

3a = 0 + 4

Combine like terms: 0 + 4 = 4

3a = 4

Divide each side by '3'.

a = 1.333333333

Simplifying

a = 1.333333333

Solution

a = {0, 1.333333333}

Answer:

r = 11.94

Step-by-step explanation:

Circumference Formula:

C = 2πr

75 = 2(3.14)r

75 = 6.28r

r = 75/6.28

r = 11.94

Answer:

Step-by-step explanation:

Midsegment means it's the middle, or half-way .  It chops the sides into even parts.  The line that's the midsegment is going to be parallel to the base and half the size of the base.  In other words, double the midsegment and that's equal to the base.  Then, just solve for x.

Answertank cu

Step-by-step explanation:

Answer:

Answer:

Charlene earns $700 per week

Kristi earns $550 per week

Sascha earns $800 per week

Step-by-step explanation:

Since Kristi earns 150 less than Charlene which is 100 less than Sascha, this is equal to the value of Sascha minus 250. We put this in the equation as s-250.

Together, they all earn $2050, so we must equal this to Charlene's value k+150, plus Kristi's value k, plus Sascha's value s.

k+150+k+s=2050

The next step here is to put the variables on one side and to put the numeric values on the other.

2k+s=1900

Like we said before, Kristi's value is equal to s-250, so we would replace k with that expression.

2(s-250)+s=1900

2s-500+s=1900

3s=2400

s= 800

We now have Sandra's weekly pay, which we can use to find the others' pay.

c= s-100

c= 800-100

c= 700

k= c-150

k= 700-150

k= 550

313.120 (round as you would like)

Step-by-step explanation:

First you take the 51.5%, and divide it by 100, you should get 0.515. Now multiply with the 608 students, your answer should be 313.20, Ta Da!!! its right!!      P.S You should also round (to 313) Please make this brainliest

Theoretical Probability:

P(rolling a 2) = 16.7%

P(rolling a 5) = 16.7%

P(rolling 2 or 3) = 33.4%

P(greater than 4) = 33.4%

P(3 or less) = 50.1%

Experimental Probability:

P(rolling a 2) = 20%

P(rolling a 5) = 6%

P(rolling 2 or 3) = 36%

P(greater than 4) = 24%

P(3 or less) = 54%

Explanation:

Theoretical probability can be calculated based on the idea that each of the six numbers on the die has an equal chance of being rolled and all numbers' probabilities total to 100%. Experimental probability is based on the outcomes of your experiment (rolling the dice yourself).

When finding the probability of rolling a number or another number (for example, rolling a 2 or 3), just add the probabilities together (You rolled 2 ten times and 3 eight times, so the experimental probability of rolling a 2 or 3 is 18/50 = 36%)

Answer:

x=-6

Step-by-step explanation:

The only thing to do is to transpose 4 and it will become negative,so-2-4=-6

Answer:

X = -6

Step-by-step explanation:

The equation is x + 4 = -2. Make the (+4) to cross over the equal sign which makes a new equation :- x = -2 - 4

Work out the new equation:-

x = -2 - 4

NOTE: -2 - 4 = -6

Therefore x = -6

Answer:

56 degrees

Step-by-step explanation:

just cause

Answer:

56 degrees

Step-by-step explanation:

the total degrees in a quadrilateral is 360

and in a trapezoid the top two angles measure the same and the bottom two measure the same

so since one of the top angles is 124 the one beside it is too

add 124 and 124 you get 248

then subtract it from 360 and you get 112

divide 112 by 2 and you get 56 which is the angle of x

Solution :

a). [tex]$P(0)$[/tex] is true

Then ,[tex]$P(0+2)=P(2)$[/tex] is true.

         [tex]$P(2+2)=P(4)$[/tex] is true

          [tex]$P(4+2)=P(6)$[/tex] is true.

Therefore, we see that [tex]$P(n)$[/tex] is true for all the even integers : [tex]$\{0, 2,4,6,...\}$[/tex]

b). [tex]$P(0)$[/tex] is true

Then ,[tex]$P(0+3)=P(3)$[/tex] is true.

         [tex]$P(3+3)=P(6)$[/tex] is true

          [tex]$P(6+3)=P(9)$[/tex] is true.

Therefore, we see that [tex]$P(n)$[/tex] is true for all the multiples of 3 : [tex]$\{0, 3,6,9,12,...\}$[/tex]

c). [tex]$P(0)$[/tex] and [tex]$P(1)$[/tex] is true, then [tex]$P(0+2)=P(2)$[/tex] is true

[tex]$P(1)$[/tex] and [tex]$P(2)$[/tex] is true, then [tex]$P(1+2)=P(3)$[/tex] is true.

[tex]$P(2)$[/tex] and [tex]$P(3)$[/tex] is true, then [tex]$P(2+2)=P(4)$[/tex] is true.

So, we observe that  [tex]$P(n)$[/tex] is true for all the non- negative integers : [tex]$\{0, 1,2,3,4,5,6,...\}$[/tex].

d). [tex]$P(0)$[/tex] is true,

   So, [tex]$P(0+2)$[/tex] and [tex]$P(0+3)$[/tex] is true or [tex]$P(2)$[/tex] and [tex]$P(3)$[/tex] is true.

   Now,   [tex]$P(2)$[/tex] is true.

Again, [tex]$P(2+2)$[/tex] and [tex]$P(2+3)$[/tex] is true or [tex]$P(4)$[/tex] and [tex]$P(5)$[/tex] is true.

   Now, [tex]$P(3)$[/tex] is true.

Again, [tex]$P(3+2)$[/tex] and [tex]$P(3+3)$[/tex] is true or [tex]$P(5)$[/tex] and [tex]$P(6)$[/tex] is true.

Thus,

[tex]$P(n)$[/tex] is true for all the non- negative integers except 1 : [tex]$\{0, 2,3,4,5,6,...\}$[/tex].

Answer: [tex]\$ 70[/tex]

Step-by-step explanation:

Given

Hester get a fixed amount and an additional $15 for an extended warranty

Suppose x is the amount of fixed amount

for 15 television sale, the price is $1275

Thus, we can write

[tex]\Rightarrow 15(x+15)=1275\\\Rightarrow x+15=85\\\Rightarrow x=\$70[/tex]

Therefore, the fixed amount of television is [tex]\$70[/tex]

Answer:

x = length of sitcoms = 21 minutes

y = length of dramas = 42 minutes

Step-by-step explanation:

Let

x = length of sitcoms

y = length of dramas

6x + 6y = 372 (1)

2x + 6y = 288 (2)

Subtract (2) from (1) to eliminate y

6x - 2x = 372 - 288

4x = 84

x = 84/4

x = 21

Substitute x = 21 into (1)

6x + 6y = 372

6(21) + 6y = 372

126 + 6y = 372

6y = 372 - 126

6y = 246

y = 246/6

y = 41

x = length of sitcoms = 21 minutes

y = length of dramas = 42 minutes
