Answer:
8.0 billion
Step-by-step explanation:
1.2÷100=0.012
0.012×6.5=0.078
2017-2001=16
0.078×16=1.248
6.5+1.248=7.748

At the beginning of last year,there were 368 students at the elementary school.By the beginning of this year,72 of those students have moved to other school districts and 64 new students arrived. about how many students started the school year this year
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.

If x is greater than 0, what is the difference of 6x√14x - 5√56x^3 in simplest radical form?
Answer:
6x√14x - 5√56x^3 = -4√14x√x
I hope this helps at least. :)
Simply put, expressing a radical in its lowest extreme form implies simplifying it and that there are no more squared roots, cube roots, 4th roots, and so on to find. This also entails eliminating any radical from a fraction's base, and further calculation can be defined as follows:
Given:
[tex]\to \bold{6x\sqrt{14x} - 5\sqrt{56x^3}}[/tex]
To find:
simplest radical form=?
Solution:
[tex]\to \bold{6x\sqrt{14x} - 5\sqrt{56x^3}}[/tex]
[tex]\to \bold{6x\sqrt{14x} - 5 \sqrt{4 \times 14 \times x \times x \times x}}\\\\\to \bold{6x\sqrt{14x} - 5 \times 2x \sqrt{ 14 x}}\\\\\to \bold{6x\sqrt{14x} -10x \sqrt{ 14 x}}\\\\\to \bold{\sqrt{14x} (6x-10x)}\\\\\to \bold{\sqrt{14x} (-4x)}\\\\\to \bold{-4x\sqrt{14x} }\\\\[/tex]

- 3x - 10 = 32
X = 14
X = -14
X = -10
x =10
Answer: -14
Step-by-step explanation:
-3x-10=32
Since the 10 is negative you have to add 10 on the right side of the equal sign. you add 10 to the negative 10 and it cancels out and becomes zero. Then you have to add 10 to the 32 and it becomes 42. Divide the 42 by negative 3 and you get -14.

Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
y=-3x + 3
y=-3x - 6
y = 3x - 3
y = 3x - 1
Answer:
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.
Step-by-step explanation:
We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
The equation will be of slope-intercept form: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept
We are given slope m =-3, we need to find y-intercept b
Finding y-intercept
using slope m=-3 and point (-1, 6)
[tex]y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3[/tex]
So, y-intercept b is 3
Now the equation of line having slope m= -3 and y-intercept b = 3 is
[tex]y=mx+b\\y=-3x+3[/tex]
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500.If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is
Answer:
20x + 45y = 9500 is the linear equation for given scenario
Step-by-step explanation:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Therefore, the linear equation for given scenario is found
Answer:
20x + 45y = 9500
yes/no: no
Solution:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
If eve raises exactly $9,500, it is NOT possible for there to be 220 participants in the 5K race.

Answer:
The answer is D. and E.
Step-by-step explanation:
The answer is D and E because 10 multiplied by 2 is 20 and 20 is bigger then 12 and 10 times 3 is 30 which is also bigger than 12.

From the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
10p - 8 >12
10p > 12 + 8
10p > 20
p > 2
p ∈ (2, ∞)
Thus, from the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.

1. If the diameter of a circular object is 10 feet. Find the radius and the circumference. Use 3.14 for π.
2. Find the perimeter of the window. R = 4ft
Answer:
1.
[tex]Radius = 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
2.
[tex]Perimeter = 25.12\ ft[/tex]
Step-by-step explanation:
Solving (1):
Given
[tex]Diameter = 10ft[/tex]
Required
Determine the radius and circumference
Radius is calculated as follows:
[tex]Radius = \frac{1}{2} * Diameter[/tex]
[tex]Radius = \frac{1}{2} * 10ft[/tex]
[tex]Radius = 5ft[/tex]
The circumference is calculated using:
[tex]Circumference = 2 * \pi * Radius[/tex]
[tex]Circumference = 2 * 3.14 * 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
Solving (2):
Given
[tex]R = 4ft[/tex]
Assume that the window is circular, the perimeter is calculated as follows:
[tex]Perimeter = 2 * \pi * R[/tex]
[tex]Perimeter = 2 * 3.14 * 4ft[/tex]
[tex]Perimeter = 25.12\ ft[/tex]

find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if necessary.
Answer:
y=1 3/5x+-5
Step-by-step explanation:
So the y intercept is where your slope meets the middle, basically the y. So it hit the y on -5. And the rise and run 8/5 rise is 8 and run is 5. 8/5= 1 3/5. in equation it is y=1 3/5x+-5.

Step-by-step explanation:
given cot A= 40/9 and that angle A is in quadrant 1 find the exact value of sec A in the simplest radical form using a rational denominator
Answer:
41/40Step-by-step explanation:
Given cotA = 40/9
1/tanA = 40/9
tanA = 9/40
According to SOH, CAH, TOA
tan A = 9/40 = opposite/adjacent
Get the hypotenuse
hyp² = opp²+adj²
hyp² = 9²+40²
hyp² = 81+1600
hyp² = 1681
hyp = √1681
hyp = 41
Het sec A
sec A = 1/cosA
Since cos A = adjacent/hypotenuse
cos A = 40/41
secA = 1/(40/41)
SecA = 41/40
Hence the exact value of secA is 41/40
