Answer:
d. 242..................
Answer:
d
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 5, thus
[tex]S_{11}[/tex] = [tex]\frac{11}{2}[/tex] [ (2 × - 3) + (10 × 5) ]
= 5.5(- 6 + 50)
= 5.5 × 44
= 242 → d

what describes an equation that has a solution set of "all real numbers"
Answer:
Any value you choose for x will make the equation a TRUE statement. This type of equation is called an identity, and the solution set is all real numbers.
An identity is an equation that, regardless of the values used, is always true.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
An identity is an equation that, regardless of the values used, is always true.
For the linear equation y = mx + c, all the values of the variable x are real numbers because the quadratic function is defined.
For the quadratic equation y = (x - h)² + k, all the values of the variable x are real numbers because the quadratic function is defined.

Answer:
The third one x+49+28=180
Step-by-step explanation:
We can say that the angle between the 29° angle and the 49° angle is equal to x, since they are vertically opposite angles.
The sum of 28+49+x is equal to a supplement angle which is a straight line essentially
We can then say x+28+49=180
:)
If you want to calculate x,
x=180-28-49

Karim is driving his car at a constant speed. At 11:00 A.M., the mileage reader is 66,750 miles. At 3:00 P.M., the mileage reader is 67,015 miles.
What is his speed in miles per
hour? Explain.
Answer:
His speed is 66.25 miles/hour
Step-by-step explanation:
The rule of the constant speed is:
Speed = Distance ÷ Time
∵ Karim starts his journey at 11:00 a.m. and finishes at 3:00 p.m.
→ Count the hours from 11: 00 a.m. to 3:00 p.m.
∴ He takes 4 hours ⇒ (3 + 12 - 11)
∴ T = 4 hours
∵ The mileage reader is 66,750 miles at 11:00 a.m.
∵ The mileage reader is 67,015 miles at 3:00 p.m.
→ The distance that Karim is driving = the difference between them
∴ The distance that karim is driving = 67,015 - 66,750
∴ D = 265 miles
→ Substitute the values of D and T in the rule above
∵ S = 265 ÷ 4
∴ S = 66.25 miles/hour
∴ His speed is 66.25 miles/hour

John and kim shared $2400 dollars in the ratio 2:6.What is kim's share ?
Answer:
$1800
Step-by-step explanation:
John's portion can be represented as 2x and Kim's portion can be represented as 6x as this will still be in a ratio of 2:6. The total of 2x and 6x equals 2400 so 8x = 2400 so divide both sides by 8 to find that x = 300. Kim's portion is 6x so 6(300) equals 1800.

Step-by-step explanation:
Question 7
Total amount of juice = 1 4/6 + 2 + 2 + 2 + 2 2/6 + 2 5/6 + 2 5/6 + 3 = 56/3
Number of children = 8
If the juice was shared equally: 56/3 ÷ 8 = 7/3 = 2 1/3 each
Therefore, each child will get 2 1/3 quarts of juice each

4m – 3(m + 1) – 4 < 0
Answer:1m-7<0
Step-by-step explanation:
4m-3m-3-4
1m-7<0
The solution to the inequality 4m - 3(m + 1) - 4 < 0 is m < 7.
We have,
To solve the inequality 4m - 3(m + 1) - 4 < 0, we can follow these steps:
Simplify the expression inside the parentheses:
4m - 3(m + 1) - 4 = 4m - 3m - 3 - 4 = m - 7.
Rewrite the inequality:
m - 7 < 0.
Add 7 to both sides of the inequality to isolate the variable:
m - 7 + 7 < 0 + 7,
m < 7.
Therefore,
The solution to the inequality 4m - 3(m + 1) - 4 < 0 is m < 7.

What is 145.4 - 140.02 ?
Answer:
5.38
Step-by-step explanation:
145.4 - 140.02 = 5.38In a tropical rain forest, the temperature ranges from 22 degrees Celsius to 30 degrees Celsius. Write and solve a compound inequality that represents the possible temperatures (in degrees Fahrenheit) of a tropical rain forest.
Answer: 71.6°< F< 86°
Step-by-step explanation:
Let C= temperature in tropical rain forest (in Celsius)
Given: In a tropical rain forest, the temperature ranges from 22° C to 30° C.
The compound inequality that represents the possible temperatures of a tropical rain forest.
22° < C < 30°
Since, [tex]\dfrac95C=F-32\Rightarrow\ F=\dfrac95C+32[/tex]
Also, At C= 22 , [tex]F= \dfrac95(22)+32=71.6[/tex]
At C= 30 , [tex]F= \dfrac95(30)+32=86[/tex]
Hence, the compound inequality that represents the possible temperatures (in degrees Fahrenheit) of a tropical rain forest.
71.6°< F< 86°
Answer:
71.6 <= T =<86
Step-by-step explanation:
celsius= 22 a.k.a Fahrenheit= 71.6
celsius= 30 a.k.a Fahrenheit= 86
so the degree ranges from 71.6 or more to 86 or less so
Use T for tempature this is an and problem so you write it like this
71.6 <= T =<86
in english this is saying that T ( tempature ) is more or equal to 71.6 and is less or equal to 86.
