Answer:
B, D = yes; others = no
Step-by-step explanation:
Recognize that "at most" means "less than or equal to." Sarah's spending must satisfy ...
3.50 + a ≤ 9.00
Subtracting 3.50 from both sides gives ...
a ≤ 5.50 . . . . . . . . . matches the second inequality shown
__
The graph of this will be shaded to the left, where 'a' values are less than the limit. The graph will have a solid dot at 5.50, where a = 5.50 is an allowed solution. This description matches the first number line shown.
_____
Point of clarification
We have used a red X to indicate that the corresponding inequality or graph is not an appropriate choice. It does not mean that the "NO" answer is incorrect. Rather, it means the answer is "NO."
3. There are 25 students in the debate
club. Of those students, 15 are girls.
What percent of the students in the
debate club are girls?
ANSWER Quick PLEASE
Answer:
60%
Step-by-step explanation:
To make a percent, it needs to be out of 100. So, the fraction would be 15/25. To make it 100, multiply each by 4 to get 100 since 25 times 4 equals 100. 15 times 4 is 60, so its 60 percent.
Answer:
In the debate club, 60% of the students are girls.
Step-by-step explanation:
(15) girls divide by total students(25)
15/25 = .6
.6*100 = 60%

Step-by-step explanation:
Find the final hourly wage if a $10.50 starting wage is increased by 6% each year for 7 years.
Answer:
In seven years the hourly rate will be $15.79.
Step-by-step explanation:
Giving the following information:
Hourly rate= $10.5
Number of periods= 7 years
Increase rate (i)= 6%
To calculate the hourly rate in 7 years, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 10.5*(1.06^7)
FV= $15.79
In seven years the hourly rate will be $15.79.

Step a: Distribute 4 through the parentheses.
[tex]y=2+4(x)+4(-3)[/tex]
[tex]y=2+4x-12[/tex]
Step b: Simplify by combining like terms.
[tex]y=4x+(2-12)[/tex]
[tex]y=4x-10[/tex]
Step c: Is the equation in the form [tex]y = mx + b[/tex]? If not, rewrite it.
The equation [tex]y=4x-10[/tex] in the form of [tex]y = mx + b[/tex].
Therefore, the slope intercept form of the given equation is [tex]y=4x-10[/tex].

The sum of-3 and four times a number is no more than -11." Whats the inequality
Answer:
-3+4x<=-11
No more than is <=
The inequality for the sum of-3 and four times a number is no more than -11 is -3 + 4x ≤ -1.
The relationship between two expressions or values which are not equal is called inequality. It shows how many times one expression is less than or equal, or greater than another expression.
Let the unknown variable is [tex]x[/tex].
According to the question,
The sum of -3 and four times of number be [tex]4x - 3\\[/tex] is less than -11.
So, the equation will be,
[tex]- 3 + 4 x < -11[/tex].
Thus, the inequality will be [tex]- 3 + 4 x < -11[/tex] .

What is the initial value of the linear function through
can you figure out the missing number in this sequence?
2, 5, 9, 14, 27
Answer:
The missing number in the sequence is 20
Step-by-step explanation:
The difference between the numbers are as follows: 3,4,5,6,7
The missing number of the given sequence is 13.
The given sequence is,
2, 5, 9, 14, 27
We can see that the difference between each consecutive number is increasing.
The difference between 2 and 5 is 3,
The difference between 5 and 9 is 4,
The difference between 9 and 14 is 5,
And the difference between 14 and 27 is 13.
Therefore, it's possible that the next number in the sequence could have a difference of 14 or more.
So,
To determine the missing number,
We can look at the pattern of the differences between the numbers in the sequence.
Since the difference between 14 and 27 is 13,
We can assume that the difference between the missing number and 27 is at least 14.
Therefore, we can subtract 14 from 27 to get our missing number, which is 13.

a3 = 18 and a6 = -486
Find a10
Answer:
The value of a₁₀ is -1158
Step-by-step explanation:
a₃ = 18
a₆ = - 486
Now,
a₃ = 18 can be written as
a + 2d = 18 ...(1) and
a₆ = - 486 can be written as
a + 5d = - 486 ...(2)
Now, from equation (2) we get,
a + 5d = - 486
a + 2d + 3d = - 486
18 + 3d = - 486 (.°. a + 2d = 18)
3d = - 486 - 18
3d = - 504
d = - 504 ÷ 3
d = - 168
Now, for the value of a put the value of d = -168 in equation (1)
a + 2d = 18
a + 2(-168) = 18
a - 336 = 18
a = 18 + 336
a = 354
Now, For a₁₀
a₁₀ = a + 9d
a₁₀ = 354 + 9(-168)
a₁₀ = 354 - 1512
a₁₀ = -1158
Thus, The value of a₁₀ is -1158

PLEASE HELP WILL MAKE BRAINLIEST
Answer:
The inside angle b is 50
Step-by-step explanation:
Since the angles of a triangel must = 180 degrees we subtrace 75 from 180 to get 180-75=105 and from there we know that angle a must be equal to angle c so 75+50-125 and then 180-125 = 55 so the inside angle of A must be 55 we get 105 back and subtract 55 from that to get 50 so b is equal to 50
Answer:
That would be 55 degrees my good sir ( or ma'am )
the 50 and 75 degree angles add up to 125 but since all straight lines are 180 you would subtract 125 from 180 degrees getting 55 degrees on angle BCN which is the same as angle ABC
Therefore its 55 degrees.

What is the result when 2x + 9 is taken away from -7x + 2
Answer:
-9x - 7
Step-by-step explanation:
When we say "taken away", we normally mean subtraction. Thus, we are subtracting 2x + 9 from -7x + 2. We are trying to find:
(-7x + 2) - (2x + 9)
Lets find the result:
(-7x + 2) - (2x + 9) = -7x + 2 - 2x - 9
= -7x - 2x + 2 - 9
= (-7 - 2)x + (2 - 9)
= -9x - 7
So subtracting 2x + 9 from -7x + 2 results in -9x - 7.

Find the areas of the sectors formed by ∠DFE. Round your answers to the nearest hundredth.
Answer:
Area of sector DFE = 177.79cm²
Area of sector DGE = 437.65cm²
Step-by-step explanation:
Find the diagram attached;
Area of the sector is expressed according to the formula;
Area of the sector = theta/360 * πr²
theta is the central angle = 360 - 256
theta = 104°
r is the radius = 14cm
Substitute into the formula as shown;
Area of the sector = theta/360 * πr²
Area of the sector DFE = 104/360 * 3.14(14)²
Area of the sector DFE = 0.289 * 615.44
Area of the sector DFE = 177.79cm²
Hence the area of the sector <DFE to the nearest hundredth is 177.79cm²
For sector DGE:
Area of the sector DGE = 256/360 * 3.14(14)²
Area of the sector DGE = 0.7111 * 615.44
Area of the sector DGE = 437.65cm²
Hence the area of the sector <DGE to the nearest hundredth is 437.65cm²
