Write all the names of the quadrilateral shown.
Answer:
see explanations
Step-by-step explanation:
The given figure has four equal sides, and all adjacent sides are perpendicular to each other.
Quadrilateral is a any figure with four sides.
Particular quadrilaterals have specific names.
A square is a quadrilateral with equal sides, each perpendicular to the adjacent side, as shown in the figure.
A rectangle is a quadrilateral of which all sides are perpendicular to the adjacents. Therefore opposite sides are equal. Adjacent sides MAY or MAY NOT be equal. Therefore a square is also a rectangle.
A rhombus is a quadrilateral of which all four sides are equal, but adjacent sides MAY or MAY NOT be perpendicular. Therefore a square is also a rhombus.
A trapezoid (or trapezium, depending on which side of the atlantic you live) is a quadrilateral with AT LEAST one pair of parallel sides. The other pair may or may not be equal, may or may not be parallel. Therefore a square is also a trapezoid (trapezium).
A quadrilateral is any plane figure with four sides, which may or may not be parallel, may or may not be equal, and adjacent sides may or may not be perpendicular. Therefore a square is also a quadrilateral.
So the given figure could be given all six possible names indicated in bold. However, the name square is most specific.

Pls answer 17 and 18 I will give brainist
Answers:
17. B18. BStep-by-step explanation:
17. We need to understand what an indirect proof is. In an indirect proof, you prove a statement by showing that the negation of the statement is false.
The "then" part of the conditional is the "to prove" statement.
In an indirect proof, we assume the opposite of what we want to prove, this is also called proof by contradiction.
So if we need to prove angle A is not an obtuse angle, we will assume it is and then use the proof format to show that angle A cannot be obtuse.
The answer is B: Assume angle A is an obtuse angle18. This question is asking us to use an indirect proof again. The "then" part of the statement is "KL > JK" and is the "to prove" statement.
We need the opposite of this, which would be assuming that KL < JK.

Answer:
The cross-section of the rectangular prism is a:
rectangleStep-by-step explanation:
When you take a cross-section of a rectangular prism, regularly you will obtain a rectangle because this was the base or the two-dimension figure that was used to form the three-dimension figure, in this case, the rectangular prism, the form of obtaining other figure is using how reference the square face, in that case, the cross-section would be a square, this happens because the cross-section is bind with the reference face. Possibly you think the cross-section in the figure doesn´t appear a rectangle, this happens by the perspective because we are looking at the rectangular prism with an inclination of 45°, but if the inclination was 90°, you would see a blue rectangle.

Carmen, Reuben, and Jim sent a total of 156 text messages over their cell phones during the weekend. Jim sent 6 fewer messages than Carmen. Reuben sent 4
times as many messages as Jim. How many messages did they each send?
Answer:
Step-by-step explanation:
1) determine what we know. We know that...
a) 156 total messages were sent
b) Jim sent 6 less that carmen
c) reuben sent 4 times as many as jim
2) create an equation with the information we know
(J= amount of messages jim sent, R= amount of messages reuben sent and C= amount of messages carmen sent)
(jim) (reuben) (carmen) (total)
C - 6 + J(4) + C = 156
Now, isolate "C" on one side of the "="
3) add 6 to both sides of the equation:
C - 6 + J(4) + C =156
-6 -6
C + J(4) + C = 150
4) Combine like terms. In this case, combine the two Cs into Cx2:
C(2) +J(4) = 150
5) subtract "J(4)" from both sides of the "="
C(2) + J(4) = 150
-J(4) -J(4)
C(2) = 150 - J(4)
6) to isolate just 1 C, divide everything by 2
{C(2) = 150 - J(4)} ÷ 2
C = 75 - J(2)
7) Go back to our original equation (in bold) and replace "C" with "75 - J(2)"
(75-J(2)-6) + J(4) + (75-J(2)) = 156
Now solve for J.
Thats as far as I got.

Answer:
[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]
Step-by-step explanation:
Given
[tex]h(x) = 3(x+2)^2[/tex]
[tex]h(x) = (fog)(x)[/tex]
Required
Find possible expressions for f(x) and g(x)
[tex]h(x) = (fog)(x)[/tex]
This can be rewritten as:
[tex]h(x) = f(g(x))[/tex]
Recall that [tex]h(x) = 3(x+2)^2[/tex]
So;
[tex]h(x) = f(g(x)) = 3(x+2)^2[/tex]
[tex]f(g(x)) = 3(x+2)^2[/tex]
By comparison, the expression in bracket represents g(x);
Hence;
[tex]g(x) = x + 2[/tex]
Replace g(x) with x
[tex]f(x) = 3(x)^2[/tex]
[tex]f(x) = 3x^2[/tex]
Hence, the possible expressions of f(x) and g(x) are:
[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]

The sum of 4 and three times a number is 19
Answer:
5
Step-by-step explanation:
Let x be that number.
4 + 3 × x = 19
4 + 3x = 19
Add -4 on both sides.
4 + 3x - 4 = 19 - 4
3x = 15
Divide both sides by 3.
(3x)/3 = 15/3
x = 5
Answer:
4+3x=19 so, x=5
19-4= 15, 15/3=5 or 5*3=15, 19-15=4.

John cut a paper square with a perimeter of 18 inches into two rectangles. The perimeter of one of the rectangles is 10 inches. What is the perimeter of the second rectangle?
Answer:
17 inches
Step-by-step explanation:
The original square had sides of 4.5 (18/4)
To get a perimeter of 10, we know that two sides would already equal 9 (4.5+4.5). That means we only have 1 inch for the other two sides, so they are each 1/2 inch.
That leaves the second rectangle with a length and width of 4.5 and 4.

To determine the surface area and volume of a cone, the three values you need are the slant height, altitude, and Question 3 options: A) arc length. B) circumference. C) radius. D) diameter.
Answer:
radius is the other quantity needed, which appears listed as option C in the list of possible answers.
Step-by-step explanation:
Recall that the volume of a cone is given by the formula:
[tex]Vol=\frac{1}{3} B\,*\, H[/tex]
where B is the area of the base:
[tex]B=\pi\,R^2[/tex]
with R being the cone's radius at the base, and H the cone's height.
The formula for the surface area of the cone also needs the size of the radius.
Therefore, the radius is the other needed quantity.
Answer:
C) Radius.
Step-by-step explanation:
When looking at a shape like this is is crucial to know the circumference because Area is L*W*H In order to determine your width you will need the Radius.
Determine the slope of the lines parallel and perpendicular to -4x+3y=11
Answer:
parallel = 4/3
perpendicular =-3/4
Step-by-step explanation:
Solve for y
-4x+3y=11
Add 4x to each side
3y = 4x+11
Divide by 3
y = 4/3 x +11/3
This is in the form y = mx+b where m is the slope
m =4/3
The parallel line has the same slope
parallel slope is 4/3
The perpendicular line has a negative reciprocal slope
m = -(1 /4/3) = - 3/4
Answer:
[tex]\frac{4}{3}[/tex] and - [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 11 ( add 4x to both sides )
3y = 4x + 11 ( divide all terms by 3 )
y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{11}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes, thus
slope of parallel line = [tex]\frac{4}{3}[/tex]
Give a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{3} }[/tex] = - [tex]\frac{3}{4}[/tex]

PLZ HELP!!! Find the measure of BAC
Answer:
<BAC = 20°
Step-by-step explanation:
It is given in the question that all 9 triangle which are formed are congruent, which means that in all triangles, the angle which is formed at point A is same.
Which means 9 angles collectively can be written as 9 · <BAC
If we consider all the 9 triangles, we can see in the figure that it forms a semicircle.
A semicircle has a total sum of angles equal to 180°
So we can write that:
9 · <BAC = 180°
Simplify for <BAC
<BAC = 20°

30 dividido pra 2 dá 15.Which distribution is positively skewed?
Answer:
D
Step-by-step explanation:
not positive but i think it would be D
Option C is the distributions are positively skewed.
Since, A distribution that is positively skewed would have the following highlights:
More points on the left, if represented on a dot plot
Tall bars on the left, if represented on a histogram
Whisker on the left, if represented on a box plot
The above means that none of the distributions are positively skewed.
This is so because:
A is negatively skewed because the whisker is at the right
B and C are symmetrical because there are tall bars at the middle
D is positively skewed because the whisker is at the left.
Hence, Option D is the distributions are positively skewed.

△MNO ~△DEF. Identify the perimeter and area of △MNO to the nearest tenth. PLEASE HELP!!!
Answer:
Option A: P ≈ 38.7 in, A ≈ 63.7 in²
Step-by-step explanation:
We are told that △MNO ~△DEF. This means that they are similar triangles.
We can solve for this using scale factor.
a) Perimeter of △MNO
The scale factor of two similar triangles is equal to the ratio of the perimeter of the triangles
Scale factor(k) = ratio of the sides of the triangles
In the diagram we are given
Side of △MNO = 6.7in
Side of △DEF = 9in
Perimeter of △MNO = X
Perimeter of △DEF = 52in
Scale factor (k) = 6.7/9
Hence,
6.7/ 9 = X/52
Cross Multiply
9X = 6.7 × 52
X = 6.7 × 52/9
X = 38.711111111 inches
To the nearest tenth, Perimeter of △MNO = 38.7 inches
b) Area of △MNO
The square of the scale factor of two similar triangles is equal to the ratio of area of the triangles
Scale factor(k) = ratio of the sides of the triangles
In the diagram we are given
Side of △MNO = 6.7in
Side of △DEF = 9in
Area of △MNO = Y
Area of △DEF = 115in²
Scale factor (k) = 6.7/9
Hence,
(6.7/ 9)² = Y/115
6.7²/9² = Y / 115
Cross Multiply
9² × Y = 6.7² × 115
Y = 6.7²× 115 /9²
Y = 63.732716049 square inches
To the nearest tenth, Area of △MNO = 63.7 in²
