A quadrilateral is shown. One pair of opposite sides have lengths of 10 inches and (x + 2) inches. The other pair of opposite sides have lengths (x + 5) inches and (2 x minus 3) inches. Based on the measures shown, could the figure be a parallelogram? Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 13 in. Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 8 in. No, there are three different values for x when each expression is set equal to 10. No, the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.

find the surface area of each figure. round to the hundredths place
Given:
In the given cone,
Radius of the cone = 7.2 m
Slant height of the cone = 17 m
To find:
The surface area of the cone.
Solution:
The surface area of a cone is:
[tex]A=\pi rl+\pi r^2[/tex]
Where, r is the radius of the cone and l is the slant height of the cone.
Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get
[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]
[tex]A=384.336+162.7776[/tex]
[tex]A=547.1136[/tex]
[tex]A\approx 547.11[/tex]
Therefore, the surface area of the given cone is 547.11 square m.

What is the measure of angle 7?
Answer:
82 degrees is the answer
Step-by-step explanation:
angle 6 and 7 are adjacent angles and adjacent angles add up to 180 deg. thus
angle 7 = 180 - 98 = 82 deg
The measure of ∠6 and ∠7 are on a straight line. This means there sum is equals to 180 degrees. Therefore, the measure of ∠7 is 82 degrees.
What is the sum of angle on a straight line?The sum of angle on a straight line is 180 degrees. This simply means the total angle on a straight line is 180 degrees.
∠6 = 98 degrees
Therefore,
∠6 + ∠7 = 180°(angles on a straight line)
∠6 = 98 degrees
Hence,
98 + ∠7 = 180
subtract 98 from both sides
98 - 98 + ∠7 = 180 - 98
∠7 = 82 degrees.

A bag contains five blue marbles, five red marbles, five white marbles, and five black marbles. You draw a marble from the bag, and then draw another marble from the bag.
Do you have a greater probability of drawing two blue marbles if you replace the first marble after you draw it or if you don't replace the marble?
Your answer should include both the mathematical proof and a written statement.
Answer:
If you replace the first marble, you have a higher chance of picking two blue marbles. Mathematical proof and written statement is shown below.
Step-by-step explanation:
Mathematical Proof :
For proof, we should test it out.
To find the total amount of marbles, we add up all the different colors in the bag.
5 + 5 + 5 + 5 = 20
Drawing 2 blue marbles while replacing the first probability :
The probability of drawing a blue marble at first is 5/20. If you then replace this marble, the probability doesn't change, it's still 5/20. To get the probability of getting two blue marbles and not replacing we multiply :
5/20 * 5/20 = 25/400 = 1/16
Drawing 2 blue marbles while NOT replacing the first probability :
The probability of first choosing a blue marble is 5/20, but you don't replace it, so now the probability of choosing a blue marble is 4/19, since one blue marble was taken. To find the probability of drawing two blue marbles but not replacing the first one we are going to have to multiply 5/20 * 4/19. That's 1/19.
So the probability of getting two blue marbles and replacing the first is 1/16, and the probability of getting two blue marbles and not replacing the first is 1/19. Well, which is greater? 1/16 is greater. If you replace the first marble, you have a higher chance of picking two blue marbles.
Written Statement :
If you replace the first marble you have a higher chance of getting two blue because you are increasing the number of blue marbles in the 20 total marbles. Now there is a greater number of blue marbles there is a greater chance you will pick blue.

Step-by-step explanation:
Explain the difference between solving a system by graphing and solving a
system algebraically.
Answer:
If you were going to solve 2 linear equations graphically, you would graph each equation, and the point where they intersect would be the solution.
One advantage is that you can see what
the curves look like. One disadvantage
is that graphing is not as accurate as
an algebraic solution. When graphing,
a point might fall between lines and
you will have to estimate thelocation.
Elimanation and substitution are the
two methods normally used for solving
a system of 2 equations. One method is
not always better than the other,It
depends on the user and the complexity
of the equations.

every parallelogram is a square?
every rectangle with four congruent sides is a square?
every rectangle is a quadrilateral?
every quadrilateral is a rectangle?
Answer:
every parallelogram is a square? False
every rectangle with four congruent sides is a square? True
every rectangle is a quadrilateral? True
every quadrilateral is a rectangle? False
Step-by-step explanation:
every parallelogram is a square?
A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.
every rectangle with four congruent sides is a square?
Square require 4 congruent sides and 4 right angles. Rectangles already have 4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.
every rectangle is a quadrilateral?
A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.
every quadrilateral is a rectangle?
A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.

Bradley wants to build a shop in his backyard. He knows the shop will be a rectangular shaped building. He wants the length of the shop to be the expression of 3x + 23 and the width to be 2x + 17. Write a trinomial that would represent the area of the shop. Show your work
Answer:
A = 6x² + 97x + 391
Step-by-step explanation:
Given that,
The length of the shop, l = (3x+23)
The width of the shop, b = (2x+17)
The expression for the area of the shop is given by :
A = lb
Put all the values,
A = (3x+23) × (2x+17)
= 6x² +51x+46x +391
= 6x² + 97x + 391
Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.
