Answer:
572.3
Step-by-step explanation:
Diameter = 27m
Radius = d / 2 = 27 / 2 = 13.5m
Area = pi x r²
= 3.14 x (13.5)²
= 3.14 × 182.25
= 572.3

Answer:
the correct option is 75
Step-by-step explanation:
The standard notation for how to write tables is in the next way.
[tex]\left[\begin{array}{ccc}inpt&outpt\\x_1&y_1\\x_2&x_2\end{array}\right][/tex]
Where the input values are represented in the x-axis (the horizontal one) and the output values are on the y-axis (the vertical one).
In this case, we want to find the number of (x-value) for the height of 250.
Then we need to look at the vertical axis and find the value y = 250.
Now let's move to the right until you meet with the point.
Once you reach the point, move down to the axis, the value at which you intersect the axis is the x-value.
We can see that the point is on the middle of the x-values:
x = 70 and x = 80
Then the x-value of the point is x = 75
This means that the correct option is 75

Answer:
(c) x ≥ 0(d) reals ≥ 2Step-by-step explanation:
The square root is only defined for arguments that are greater than or equal to zero.
√x . . . . defined for x ≥ 0
It will only have non-negative values.
√x . . . . has values ≥ 0
Using these facts, we can answer the questions.
__
1. The domain is the set of values x may have. The square root function limits the domain to x ≥ 0.
__
2. The range is the set of values y may have. The square root function is never negative, so the range must be 2 or greater.
y ≥ 2

is x = -3 a solution for the following equation: 6x - 19 = 3x - 10? Be sure to show work.
Answer:
x=-3 is not a solution
Step-by-step explanation:
well, lets plug it and and see!
6(-3)-19=3(-3)-10
-18-19=-9-10
-37=-19
-37 DOES NOT equal -19.
so x=-3 is not a solution

The American Water Works Association reports that the per capita water use in a single-family home is 76 gallons per day. Legacy Ranch is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Twenty-seven owners responded, and the sample mean water use per day was 71 gallons with a standard deviation of 9.5 gallons per day. At the 0.01 level of significance, is that enough evidence to conclude that residents of Legacy Ranch use less water on average
Answer:
Yes, that is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average
Step-by-step explanation:
The data given by the American Water Works Association are;
The per capita water use in a single-family home, μ = 76 gallons per day
The number of responders in the sample, n = 27
The sample mean water used by the sample, [tex]\overline x[/tex] = 71 gallons
The standard deviation, s = 9.5 gallons per day
The level of significance, α = 0.01
The test statistics is given as follows;
The null hypothesis, H₀; μ ≥ 76 gallons
The alternative hypothesis, Hₐ; μ < 76 gallons
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
Therefore, we have;
[tex]t=\dfrac{71-76 }{\dfrac{9.5}{\sqrt{27}}} \approx -2.734817[/tex]
At n - 1 = 27 - 1 = 26 degrees of freedom, the critical-t = 2.5
From the test statistic, of t ≈ -2.734817, the p-value < 0.01, and from a graphing calculator, the p-value is given as Prob = 0.005544418
Therefore, given that the p-value is less the significant level, and less than 0.01, is therefore statistically significant, and therefore, there is sufficient statistical evidence against the null hypothesis, therefore we reject the null hypothesis, and there is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average.

Answer:
(-4,5)
Step-by-step explanation:
use elimination method to solve
x+2y=6
3x+4y=32
make the x coefficient to be equal by multiplying the x by 3
3x+6y=18
-3x+4y=32
since the signs for the z coefficient are different than you add 3x+-3x=0
6y+4y=10y
18+32=50
10y=50
y=5
if y is equal to 5 then substitute
x+(2*5)=6
x+10=6
x=-4

Answer:
The answer is (3, -3)
Step-by-step explanation:
Translating it down means subtracting from the second value, or the y value. 0 - 3 = -3. You keep the x value the same.
Answer:
C(3, -3).
Step-by-step explanation:
When it is translated down, the y-coordinate changes.
Subtract 3 from the y-coordinate.
C(3, 0) becomes C(3, -3).

If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?
Answer:
r = 6 inch
Step-by-step explanation:
Given that,
The height of a cone, h =8 inches
The slant height of the cone, l = 10 inches
We need to find the radius of the base. The relation between height, radius and the slant height of the cone is given by :
[tex]r=\sqrt{l^2-h^2} \\\\r=\sqrt{10^2+8^2} \\\\r=6\ inch[/tex]
So, the radius of its base is equal to 6 inches.
Which equation represents a line that passes through the points (4, 5) and (6, 9)? A. y = 2x-3 B. y - 3x-7 C. y= x + 3 D. y- + x + 7
Answer:
A) y=2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-5)/(6-4)
m=4/2
m=2
y-y1=m(x-x1)
y-5=2(x-4)
y=2x-8+5
y=2x-3
The polygons in each pair are similar. Find the scale factor of the smaller figure to the
larger figure.
A.2:3
B.5:7
C.1:5
D.6:7
Answer:
1 : 5
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, smaller to larger, then
3 : 15 = 1 : 5
which is greater -111 or -1111
Jason divides his first 1/2 mile of the trail into 3 sections. He puts a sign at the end of each section. If the signs are an equal distance apart, what is the distance between the second and third signs?
Answer:
1/6 mile
Step-by-step explanation:
Distance divided = 1/2 miles
No of sections = 3
Each division must equal = 1/2/3
= 1/2*1/3 = 1/6 mile.
The distance between each of the signs i.e between the first and second , second and third is 1/6 of the mile.
This can be done in decimals as well
1/2 mile= 0.5 mile.
When we divide 0.5 mile by 3 we get 0.167 which is equal to 1/6 in fractions.

Solve for x. 3.8 + 4.5x - 1.4 = 8.25
Answer:
x = 1.3
Step-by-step explanation:
Eliminate fractions first. Multiply all four terms by 100. The result will be:
380 + 450x - 140 = 825
Combine like terms:
240 + 450x = 825, or
585 = 450x, or:
x = 1.3

Given:
i) 3, -5, -2, 1
ii) -1, -8, -7, -2
iii) -2, -4, 0, 2
To find:
increasing order of the given numbers.
Solution:
Increasing order: We need to start from the smallest number, then write larger number and end with the largest number.
We know that all negative numbers are less than the positive numbers and larger negative value is always the smaller one.
For example: -3 is less than -1.
i) We have,
3, -5, -2, 1
So, the increasing order of these number is -5, -3, -2, 1.
ii) We have,
-1, -8, -7, -2
So, the increasing order of these number is -8, -7, -2, -1.
iii) We have,
-2, -4, 0, 2
So, the increasing order of these number is -4, -2, 0, 2.
