can someone help me understand this question?
Answers
This is finding the point where these two lines intersect.
The key to solving these algebraically is finding one part in terms of another part and substituting.
We can solve this system by Gaussian elimination, first by multiplying the second equation in its entirety by 2, so that the x-terms will cancel.
We have
[tex]16x-10y=10[/tex]
and
[tex]2(-8x-6y=6)[/tex].
The last equation is rewritten as [tex]-16x-12y=12[/tex].
Now, we cancel the x-terms.
[tex]16x-10y=10[/tex]
[tex]-16x-12y=12[/tex]
[tex]-22y=22 \\ y = -1[/tex]
We have our value for y, so we just plug this back into any of the original equations to get x.
[tex]16x-10(-1)=10\\16x=0\\x=0[/tex]
Thus, the solution to the system of equations is the point [tex](0,-1)[/tex].

What is 4,321,109,432 rounded to the nearest ten million?
A. 4,000,000,000
B. 4,320,000,000
C. 4,321,000,000
D. 4,322,000,000
Answers
Final answer:
The number 4,321,109,432 rounded to the nearest ten million is 4,320,000,000,hence the correct option is B.
Explanation:
To round the number 4,321,109,432 to the nearest ten million, we need to look at the digit in the ten million's place and the digit to the right of it, which are 3 and 1, respectively. The rule for rounding is that if the digit to the right is 5 or greater, we round up.
In this case, the digit is 1, so we do not round up and the ten million's place remains unchanged.
Therefore, the answer is 4,320,000,000 (Option B), as every digit after the ten million's place is replaced with zero.

The price of oil recently went from $7.80 to$10.40 per case of quarts. Find the ratio of the increase in price to the original price.
Answers
When you are looking for a ratio, it is simply a fraction.
In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.
This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).
I hope this helps, Good luck!

what formulas could be used to determine the surface area of a cylinder sandwiched between one cone and half of a sphere?
Answers
To find the surface area of a cylinder sandwiched between one cone and half of a sphere, use the sum of the cylinder's lateral surface area, the cone's lateral surface area, and half the sphere's surface area. The formula is 2πrh + πrl + 2πr², excluding the base areas where the shapes intersect.
To determine the surface area of a cylinder sandwiched between one cone and half of a sphere, you should first consider the formulas for the surface area of these individual shapes. The shapes consist of simple geometrical forms: a cylinder, a cone, and a sphere. The surface area of these shapes can be described with established formulas within the geometry:
Cylinder: The surface area of a cylinder (excluding the ends) is calculated by multiplying the perimeter of the base circle (which is 2πr, where r is the radius) by the height h of the cylinder plus the area of the two circles (2πr²). This gives: 2πrh + 2πr².Cone: The surface area of a cone is the sum of the area of its base (πr²) and the lateral surface area, which is πr times the slant height. However, if the cone is placed on one end of the cylinder and they share a base, you do not need to calculate the area of the base since it is covered by the cylinder. You would just need the lateral surface area of the cone (πrl, where l is the slant height).Sphere: Half of the surface area of a sphere is 2πr² since the full surface area is 4πr².Therefore, the final formula to calculate the total surface area of the described complex shape is the sum of the surface area of the lateral side of the cylinder, the lateral surface area of the cone, and half of the surface area of the sphere. This could be written as:
Total Surface Area = 2πrh + πrl + 2πr².
Note that you would omit the area of the circle that is common between the cylinder and the cone, as well as the area that is common between the cylinder and the half-sphere, since they are internall and not part of the external surface area.
name each angle in four ways. then classify each angle as acute, right, obtuse, or straight.
Answers
∠ABC

∠B
∠1
Acute: 4, 5
Right: 1
Obtuse: 2, 6
Straight: 3
_____
Note that only angle 1 is known to be a right angle, because it is marked as such. The others appear to have a particular measure, but since they don't have any specific indication of their measure, the appearance cannot be taken at face value. (We suspect you're supposed to use the appearance to answer this question, but don't get in that habit.)
In this geometric scenario, angles are named and classified. Angle 1 is a right angle, angle 3 is a straight angle, angles 2 and 6 are obtuse, while angles 4 and 5 are acute.
Let's name each angle in four ways and classify them:
Angle ABC (B is 90 degrees):
1 (as labeled)
∠ABC (using the vertex B)
∠CBA (using the vertex C)
∠1 (angle 1)
Classification: Right angle
Angle DEF (E is also labeled as 2):
2 (as labeled)
∠DEF (using the vertex E)
∠FED (using the vertex F)
∠2 (angle 2)
Classification: Obtuse angle
On line LN with point M (labeled as 3):
3 (as labeled)
∠LNM (using the vertex N)
∠MNL (using the vertex M)
∠3 (angle 3)
Classification: Straight angle
Angle XYZ (Y is also labeled as 4):
4 (as labeled)
∠XYZ (using the vertex Y)
∠ZYX (using the vertex Z)
∠4 (angle 4)
Classification: Acute angle
Angle KLM (L is also labeled as 5):
5 (as labeled)
∠KLM (using the vertex L)
∠MLK (using the vertex M)
∠5 (angle 5)
Classification: Acute angle
Angle RSP (S is also labeled as 6):
6 (as labeled)
∠RSP (using the vertex S)
∠PSR (using the vertex P)
∠6 (angle 6)
Classification: Obtuse angle
So, to summarize:
Right angle: 1
Obtuse angles: 2, 6
Straight angle: 3
Acute angles: 4, 5

Two rectangles are similar. If the height of the first rectangle is 3 inches, and the height of the second rectangle is 9 inches, how much longer is the second rectangle's perimeter? 3 times as long 6 times as long 9 times as long 6 inches longer
Answers
Answer:
Option a.
Step-by-step explanation:
Two rectangles are similar. Height of one rectangle is 3 inches and height of second rectangle is 9 inches.
Let width of rectangles are x inches and y inches.
Then width of the second rectangle will be in the same ratio as of their heights.
[tex]\frac{x}{y} =\frac{3}{9}[/tex]
[tex]\frac{x}{y} =\frac{1}{3}[/tex] ⇒ x = [tex]\frac{y}{3}[/tex]
Now perimeter of first rectangle P₁ = 3 + 3 + x + x = 2x + 6
Perimeter of second rectangle P₂ = 9 + 9 + y + y = 18 + 2y
Ratio of P₁ and P₂ = [tex]\frac{2x+6}{18+2y}[/tex]
= [tex]\frac{2(\frac{y}{3})+6}{18+2y}[/tex] [as [tex]x=\frac{y}{3}[/tex]]
= [tex]\frac{\frac{(2y+18)}{3} }{(18+2y)}[/tex]
= [tex]\frac{2y+18}{3(18+2y)}[/tex]
Ratio of P₁ and P₂ = ([tex]\frac{1}{3}[/tex]) ⇒ P₂ = 3P₁
Therefore, Option a is the answer.

rectangle abcd is similar to rectangle pqrs. given ab=14 cm, BC=8cm and pq=21cm, calculate the length of QR
Answers
The length of QR in rectangle PQRS is 12 cm, found by setting up the proportional relationship 14/21 = 8/QR, where 14 cm and 8 cm are the lengths of sides AB and BC of rectangle ABCD, respectively, and 21 cm is the length of side PQ of rectangle PQRS.
Since rectangle ABCD is similar to rectangle PQRS, their corresponding sides are proportional. To find the length of QR, we will set up a proportion using the given lengths:
AB/PQ = BC/QR
Substituting the given lengths:
14/21 = 8/QR
Now, solve for QR:
QR = (21 * 8) / 14
QR = 168 / 14
QR = 12 cm
So, the length of QR in rectangle PQRS is 12 cm.

Answers
First, to be a perfect square the last term must be a perfect square number. Only 169, 49 and 16 are perfect squares. Second, the middle term must be twice the square root of the last term.
You can check this by using foil on the following expression:
(x + 13)(x + 13) You will get x^2 + 26x + 169 which is one of the perfect square trinomials.
For the difference of squares, you must be using subtraction and have two perfect squares.

A student solved this problem by working backward. Janice went shopping with her mom and at the end of the day she had $59.50 left over. She spent $13.65 on a T-shirt, $22.99 on some new sandals, and $40.75 on a new skirt. How much money did Janice have at the beginning? Student's solution - Janice had $59.50 left. Add up all the amounts she spent ($13.65 + $22.99 + $40.75) and add to the amount she has left over ($77.39 + $59.50). So Janice had $136.89 to begin with. Solve this problem.

What are the second and third terms of this geometric sequence?
Answers
tₙ = t₁ · (r)ⁿ⁻¹
t₁ = -2
t₄ = 128 (4th term)
formula for 4th term:
t₄ = -2 · (r)⁴⁻¹ = -2· (r)³
since t₄ = 128
128 = -2(r)³
(r)³ = -64
r = ∛-64
r = -4
so second term is
t₂ = -2· (-4)²⁻¹ = 8
third term is
t₃ = -2 · (-4)³⁻¹ = -32
