Step-by-step explanation:

This will sound stupid search up identifying corresponding angles calculator it should help i use one all the time.

Answer:

Hi i think its 4 :)

Step-by-step explanation:

Answer: 3 is 39, 4 and 2 are 141.

Step-by-step explanation: since 3 is directly opposite to angle 1, they are equal. same goes for 3 and 4. Also, 3 and 2 create a straight line meaning they ALWAYS will add up to 180. subtract 39 from 180 and you get 141. Hope this helps :)

45+30=75=100%

75/10=7.5=10%

7.5*6=45=60%

Step-by-step explanation:

Given parameters:

Amount of discount on goods= 20%

Original price of the good  = 700

Unknown:

Total amount he saved  = ?

Solution:

The total amount he saved will be the value of the discount charged on the original price.

 Amount of discount  = Percentage discount x original price of goods

 Amount of discount = [tex]\frac{20}{100}[/tex] x 700

 Amount of discount  = 140

The amount saved is 140

Solution 1

Inspecting a 7th-degree polynomial of 'n' by taking its derivatives

From the given conditions,

 2n7+n6+2n4+2n3+2n2

=(n+1)7+(n+1)5+(n+1)4+2(n+1)3+(n+1)2+2(n+1)+1.

 2n7+n6+2n4+2n3+2n2

=n7+7n6+21n5+35n4+35n3+21n2+7n+1

 +n5+5n4+10n3+10n2+5n+1

 +n4+4n3+6n2+4n+1

 +2(n3+3n2+3n+1)

 +(n2+2n+1)+2(n+1)+1.

n7-6n6-22n5-39n4-49n3-42n2-26n-9=0 .....[1].

Let A(n)=n7-6n6-22n5-39n4-49n3-42n2-26n-9.

For n>2, A(n)<n7-6n6-22n5.

Since A(n)=0,

0<n7-6n6-22n5.

0<n5(n-3+√31)(n-3-√31).

Since n>2, n>3+√31, which means n≥9 .....[2].

Now, to differentiate A(n),

A'(n)=7n6-36n5-110n4-156n3-147n2-84n-26.

A''(n)=42n5-180n4-440n3-468n2-294n-84.

A'''(n)=210n4-720n3-1320n2-936n-294.

A(4)(n)=840n3-2160n2-2640n-936.

 A(5)(n)

=2520n2-4320n-2640

=2520{(n-6/7)2-262/147}.

If A(5)(n)=0, n=6/7±√(262/147).

Therefore, A(5)(n)>0 for n≥3.

Although n≥9 according to [2], I try inspecting A(n) for n≥10.

When n≥10, A(4)(n) increases monotonously.

A(4)(10)=840000-216000-26400-936>0.

Therefore, A(4)(n)>0 for n≥10.

And when n≥10, A'''(n) increases monotonously.

A'''(10)=2100000-720000-132000-9360-294>0.

Therefore, A'''(n)>0 for n≥10.

And when n≥10, A''(n) increases monotonously.

A''(10)=4200000-1800000-440000-46800-2940-84>0.

Therefore, A''(n)>0 for n≥10.

And when n≥10, A'(n) increases monotonously.

 A'(10)

=7000000-3600000-1100000-156000-14700-840-26>0.

Therefore, A'(n)>0 for n≥10.

And when n≥10, A(n) increases monotonously.

 A(10)

=107-6000000-2200000-390000-49000-4200-260-9>0.

Therefore, A(n)>0 for n≥10 .....[3].

From [2] and [3], A(n)=0 only when 9≤n<10.

In consequence, n=9.

Answer:

250 people

Step-by-step explanation:

Since it is mentioned in the question that the number of people who attend the music concert is 250 people

And, the attendance in a basketball game is 30% of concert attendance

Now based on the above information

The people who attended the concert is 250 people as it is already given in the question that 250 people attended the music concert

Answer:

32%

Step-by-step explanation:

For example, 32% is equal to 32÷100. As a decimal, this number is 0.32

Answer:

A)  2f / hour

B) 10 f

Step-by-step explanation:

outside temperature decreases by ; 7 F in 3 1/2 hours

a ) represent temperature change as a unit rate

To do this you will need to represent the temperature change per hour

7 f / 3.5 hours

= 7 f / 3.5 = 2 therefore the temperature change as a unit rate = 2f / hour

b) Temperature change after 5 hours

Δ temperature  in 5 hours = temperature change per hour * 5

                             = 2 F * 5 =  10 F

Answer:

its 7

Step-by-step explanation:

Answer:

The answer is A) 2.

Step-by-step explanation:

9 = -2x + 5

4 = -2x (subtracted 5 from both sides.)

2 (add -2 to both sides.)

Answer:172 days

Step-by-step explanation:

Answer:

The answer is m = 5

Answer:

m = 5

Step-by-step explanation:

5m - 3= 7m - 13

-2m-3=-13   ........ subtract 7m from both sides

-2m = -10    ......... add 3 to both sides

m = 5          ........ divide both sides by 2 and you get 5

Slope-Intercept Form: [tex]y=\frac{3}{2}x+6[/tex]

Slope:  [tex]\frac{3}{2}[/tex]

Y-Intercept: [tex](0,6)[/tex]

Step-by-step explanation:

STEP 1: Add 3x to both sides of the equation.

[tex]2y=12+3x[/tex]

STEP 2: Divide each term by 2 and simplify.

[tex]y=\frac{3x}{2} +6[/tex]

STEP 3: Reorder terms.

[tex]y=\frac{3}{2}x+6[/tex]

Answer:

9 days

Step-by-step explanation:

Given that:

Days whereby there was either corn or carrot = 12 days

There are 6 more days of corn than carrot.

How many days did we have corn?

Let Number of days we had carrot = x

Hence,

Number of days we had corn = x + 6

Total number of days we had either of the two = 12

Hence,

x + (x + 6) = 12

2x + 6 = 12

2x = 12 - 6

2x = 6

x = 6/2

x = 3

Number of days we had corn = x + 6 ;

Hence,

3 + 6 = 9
