Answers

Answer 1

Answer:

D

Step-by-step explanation:

Answer 2

Answer:

A

Step-by-step explanation:

First we need to find the perimiter of a parallelogram

Side A is the slanted line,

Side B is the 2 horizontal lines.

The equation for this is 2(a+b)

Let's plug in the measurements:

2(18+27) =

2(45) =

90

So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18

90 + 18 = 108

Hope this helps :)

what is 7 (x-2) simplified

Answers

Answer:

7x-14

Step-by-step explanation:

you must use the distributive property. to do this, you must multiply the value outside the parentheses (7) by the first term in the parentheses (x) and add that to the multiplication of 7 and the second term (-2). 7 multiplied by x is 7x, and 7 multiplied by -2 is -14. when you add these two values, you get 7x-14.

Find the area of the trapezoid 2 2 2 2 4

Answers

Answer:

It is 10.

Step-by-step explanation:

If we just find the area for each section and add them all up it would equal 10. The first triangle, 2x2=4 then divide that by 2 will equal you 2. Then the square is just 2x2 =4. Then the last triangle, 2x4=8 then divide that by 2 = 4. 2+4+4=10.

Answer:

Correct answer is (10)

Step-by-step explanation:

since 2 triangles come together to form a square\rectangle

length * width = Area

we can find both areas of the triangles:

left triangle: 2*2 = 4 --> 4 devided in half = 2

square area = 4

right side triangle: 2*4 = 8 ---> devided in half = 4

______________________________________

next add up all the measurements for each piece:

left triangle + middle square + right side triangle = area

(2+4+4 = 10)

Plz help! Giving brainliest to a complete and correct answer. Absurd answers will be reported.

Answers

Answer:

Use absolute difference

Step-by-step explanation:

Given

The given parameters can be represented as:

[tex]Expense > Income[/tex]

[tex]Income - Expense< 0[/tex]

Required

Eliminate negative difference

To eliminate negative difference, Sara has to  make use of absolute difference when calculating the difference between her income and expense.

Take for instance:

[tex]Income = 10[/tex]

[tex]Expense = 12[/tex]

The difference between both is:

[tex]Income - Expense = 10 - 12[/tex]

[tex]Income - Expense = -2[/tex]

But if she uses absolute difference, the result will be:

[tex]|Income - Expense| = |10 - 12|[/tex]

[tex]|Income - Expense| = |-2|[/tex]

[tex]|Income - Expense| = 2[/tex]

The radius and the diameter of the circle are 11 cm and 22 cm respectively.

Step-by-step explanation:

The radius of a circle is a line segment extending from the center of a circle or sphere to the circumference or bounding surface, while the diameter of a circle is a straight line passing from side to side through the center of a body or figure, commonly a circle or sphere. Since the diameter goes entirely across the circle while passing through the midpoint - or center - of a circle and the radius only goes from the edge to the midpoint, that means the diameter is twice as big as the radius. In this example, the radius is already given to you, which is 11 cm, based on the image. Using this, you can figure out the diameter of that circle would be [tex]11 * 2[/tex] or 22 cm. So the radius of the circle is 11 cm, while the diameter of the circle is 22 cm.

It’s 11 r and 22 c sooooooo yeah

how many vertices AND faces does this shape have?

Answers

Answer:

this is irregular shape it has four vertix and two faces

The number of vertices and faces this shape have is 4 and 4.

What are vertices, faces and edges?

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

We are given that;

The figure

Now,

Number of vertices= 3+1

=4

Number of faces= 3+1

=4

Therefore, by vertices the answer will be 4 and 4.

Dennis notices that if he reflects A ABC across the y-axis and then translates it down 4 units, the result is A DEF.
Eduardo says that he can first translate A ABC down 4 units and then reflect it across the y-axis in order to get A DEF.
Is Eduardo correct? Explain your answer and tell whether A ABC and A DEF are congruent.

Answer:

Step-by-step explanation:

The translation of the 4 units right then a reflection across the x-axis will map triangle ABC onto triangle DEF.

What are the translation and reflections of an image?

Translation of an image indicates the horizontal or vertical movement of that image. The reflection of an image indicates the mirror image of the given image along with a fixed-line.

Here, when we translate the triangle ABC to the right by 3 units, then point A will be at (2, 6), point B will be at (2, 3), and point C will be at (4, 3.).

Hence, after reflecting the triangle ABC, we get the triangle DEF.

Answers

Answer:

let's say x1 = y2. for instance, that would mean that for every X, y would go up by 2. That would mean -1x = Y-2 because to get to -1 you have to subtract 1 by 2 because there is still 0 to account for.

so the table would look like this

-1=-2

1=2

Answer:

y=-4/5x+2

Step-by-step explanation:

Slope-intercept form, or y=mx+b, is the linear format of a line. Y is the y-coordinate, m is the slope, x is the x-coordinate, and b is your y-intercept. Your y-intercept is the coordinate in which your y-coordinate is a number on the graph and the x-coordinate is 0. If you count the units between one plotted point and another on the graph, you can see that the graph goes down 4 units and right 5 units. This means that the slope is 4/5, but because it's a negative slope, it's -4/5. The y-intercept on your graph is (0,2), so b=2. Therefore, the equation of the line is y=-4/5x+2.

Answer:

b. 14,400 seconds (check note)

Step-by-step explanation:

a.

y=-4x

y=-35814 (negative because this is underwater)

-35814=-4x

8953.5

The model suggests it would take 8,953.5 seconds for DeepSea Challenger to reach the bottom (2.487083333 hours, or about 2 hours and 30 minutes).

b.

y=4x

x=3600 (positive because the vessel is rising)

4(3600)

14400

It took 14,400 seconds for the DeepSea Challenger to ascend to the surface.

[also note: I'm not sure if the second question is asking for how many seconds it takes to ascend to the surface with reference to the 4 seconds in the previous question (which is how I answered part b) or if it's asking how many seconds 1 hour is, and in that case. the answer is 3,600 seconds.
