Answer:
We do not have the image, so we can answer in a general way.
We know that the boundary line is y = -2*x - 5
We can have 4 cases:
1) a dashed line and the shaded part is above the line.
y > -2*x - 5
2) a dashed line and the shaded part is below the line
y < -2*x - 5
Here we have dashed lines because the values of the line are not solutions for the inequality.
3) a solid line and the shaded part is above the line.
y ≥ -2*x - 5
4) a solid line and the shaded part is below the line.
y ≤ -2*x - 5
Here we have solid lines because the values in the line itself are solutions.
Answer:
Step-by-step explanation:
The graph shows the inequality y≥−2x−5.
The line y=−2x−5 is the boundary line. On one side of the line are the points with y>−2x−5, and on the other side of the line are the points with y<−2x−5.
Let's test the point (0,0), which is inside of the shaded region, and determine which inequality describes the side of the boundary line that contains the test point.
At (0,0), which inequality is true?
The shaded region contains the point (0,0); therefore, the inequality that contains (0,0), y>−2x−5 has the correct shaded side.
Notice that since the boundary line is graphed with a solid line, the inequality includes the equal sign.

Answer:
12. median: AD; altitude: CE; midsegment: none
13. x = 2
Step-by-step explanation:
12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.
An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.
A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.
Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.

13. The base segment is twice the length of the midsegment:
2(5x -3) = x +12

consider a sphere which area (in square meters) equal to its volume (in cubic meters) what is the radius (in meters) of this sphere
Answer:
3 meters
Step-by-step explanation:
A sphere is a three-dimensional geometrical object.
Let r denotes radius of a sphere.
Area of a sphere = [tex]4 \pi r^2[/tex]
Volume of a sphere = [tex]\frac{4}{3}\pi r^3[/tex]
As a sphere which area (in square meters) is equal to its volume (in cubic meters) ,
[tex]4\pi r^2=\frac{4}{3}\pi r^3\\\\ r^2=\frac{r^3}{3}\\\\\frac{r^3}{r^2}=3\\\\[/tex]
r = 3 meters

Find the length of x
Answer:
7
Step-by-step explanation:
First, this triangle is a 30-60-90 triangle, this means that the hypotenuse is 2x, the "bottom" is x, and the other side is [tex]x\sqrt{3}[/tex].
For our purposes, we need to use the hypotenuse and the "bottom".
Since the hypotenuse is two times x, we can divide the hypotenuse to get x.
14/2 = 7
Therefore, x is equal to 7.

The union representing the Bottle Blowers of America (BBA) is considering a proposal to merge with the Teamsters Union. According to BBA union bylaws, at least three-fourths of the union membership must approve any merger. A random sample of 2,000 current BBA members reveals 1,600 plan to vote for the merger proposal. What is the estimate of the population proportion
Answer:
The answer is "(0.782, 0.818)".
Step-by-step explanation:
computing the sample proportion:
[tex]p=\frac{x}{n}= \frac{1,600}{2000}=0.80 \\\\[/tex]
[tex]\text{Computing the} \ 95\% \ \ C.I \\\\[/tex]
[tex]C.I= p \pm Z_{\frac{\alpha}{2}}\sqrt{\frac{P(1-p)}{n}}[/tex]
[tex]= 0.80 \pm 1.96 \sqrt{\frac{0.80(1-0.80)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.80(0.20)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.16}{2000}} \\\\ = 0.80 \pm 1.96 \sqrt{0.00008} \\\\=0.80 \pm 0.18 \\\\= (0.782, 0.818)[/tex]
conclusion:
Since the interval calculation contains higher values than 75 percent of its union membership, the merger proposal is likely to pass.

Answer:
12.9 square yards
Step-by-step explanation:
The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...
A = 1/2bh
A = 1/2(3 yd)(2 yd) = 3 yd²
The base area is computed using the same formula and the given height:
A = 1/2(3 yd)(2.6 yd) = 3.9 yd²
Then the total surface area is that of the base and the three faces:
SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area
If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?
Answer:
32 minutes
Step-by-step explanation:
There are 60 seconds in a minute
That means we will need to know how many feet he walks in a minute
So we would do 3 x 60 which equals 180 so he walks 180 ft per miute
Now we need to figure out how many minutes it took for him to walk 5760 ft.
So we would do 5760 ÷ 180 which equals 32
So the aswer is 32 minutes for him to walk 5760 ft.
Hope this helps
What additional piece of information is needed to show that DEF = PQR by ASA?
Answer:
The sigle line between E and D shows that it is tje same as Q AND P. SO angle D and E is the same as angle Q and P
The triangles ΔDEF and ΔPQR are congruent with each other by ASA postulates because ∠F = ∠R. Then the correct option is A.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
In triangles ΔDEF and ΔPQR,
∠DEF = ∠PRQ (Given)
DE = PQ (Given)
∠F = ∠R (Opposite sides are equal)

You do 1256÷4=314
Then you take 314 which is the cost of the dryer and you do 314*3=942 which is the cost of the washer
Answer:

The length of a rectangle is 5 inches longer than it is wide. If the perimeter is 38 inches, what are the dimensions of the rectangle?
The width, or shorter side is ______
inches.
The length, or longer side is _____
inches.
Answer:
shorter side = 7 in
longer side = 12 in
Step-by-step explanation:
Let w = width
then w + 5 = length
The perimeter of the rectangle = 2 widths + 2 lengths.
So, w + w + w + 5 + w + 5 = 38 or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.
Now 4w + 10 = 38
4w = 28
w = 7
w + 5 = 7 + 5 = 12
shorter side = 7 in
longer side = 12 in
Check: 7 + 7 + 12 + 12 = 38 = perimeter
