Which of the following must be true in order for SAND to be in a rhombus? Select all that apply
a) Consecutive sides must be congruent, for SAND to be in a rhombus
For the word "SAND" to form a rhombus, certain conditions must be met based on the properties of a rhombus:
a) Consecutive sides must be congruent: True. In a rhombus, all sides are congruent, so consecutive sides must also be congruent.
b) Diagonals do not bisect the angles: False. In a rhombus, the diagonals bisect the angles. This is a property of rhombuses.
c) All interior angles add up to 360: False. In a rhombus, all interior angles are equal, but their sum is not necessarily 360 degrees. However, the sum of all interior angles in any quadrilateral (including a rhombus) is indeed 360 degrees.
Therefore, the correct statement is:
a) Consecutive sides must be congruent
Pirate Jack has an equal number of gold and silver coins. If Pirate Jack splits all of his coins into 7 equal piles for his parrots, he has 4 coins left. Or, if he splits all of his coins into 11 equal piles for his shipmates, he has 4 coins left. Assuming every pile has at least 1 coin, what is the least possible number of coins Pirate Jack has?
The least possible number of coins Pirate Jack has, is 81 coins.
Step-by-step explanation:
Given,
When the coins are divided into 7 equal piles, 4 coins are left.
When the coins are divided into 11 equal piles, 4 coins are left.
We will take LCM of both 7 and 11.
7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, ....
11 = 11, 22, 33, 44, 55, 66, 77, 88, ...
The least common multiple of 7 and 11 is 77.
As 4 coins are left, therefore, we will add those coins.
Total possible coins = 77+4 = 81
The least possible number of coins Pirate Jack has, is 81 coins.

An image point of a transformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(6, -12), what was the transformation and scale factor?
reflection with scale factor 3
reflection with scale factor 1/3
dilation with scale factor 3
dilation with scale factor 1/3
Answer:
Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3
Step-by-step explanation:
i) the pre-image co-ordinates is Y(6, -12)
ii) the coordinates of the image is Y' (2, -4)
iii) therefore we can clearly see that if we divide the coordinates of the pre-image (6,-12) by 3 then we get the coordinates of the image(2,4).
Therefore this is a dilation with scale factor of 1/3.
Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3
Final answer:
The transformation from the pre-image point Y(6, -12) to the image point Y'(2, -4) is a dilation with a scale factor of 1/3.
Explanation:
Given an image point Y'(2, -4) of a transformation and the pre-image point Y(6, -12), we can determine the type of transformation and the scale factor. The transformation is a type of change that affects the position, size, or shape of a figure. To find out the type of transformation and the scale factor, we compare coordinates.
Since the x-coordinate changed from 6 to 2, it has been reduced by a factor of 3 (6 divided by 3 equals 2). The y-coordinate changed from -12 to -4, which also has been reduced by a factor of 3 (-12 divided by 3 equals -4). This consistent reduction indicates that the transformation is a dilation. The objects are shrunk uniformly in both dimensions by the scale factor.
The correct answer is therefore dilation with scale factor 1/3.

a + b = 10
a - b = 2
Solve the system of equations.
A) a = 5, b = 5
B) a = 2, b = 8
C) a = 6, b = 4
D) a = 3, b = 7
E) a = 12, b = -2
Answer:
C) a = 6, b = 4
Step-by-step explanation:
6 + 4 = 10
6 - 4 = 2
To solve the system, we first add both equations to find 'a = 6'. Then, substitute 'a' in one of the original equations to get 'b = 4'. The solution is 'a = 6' and 'b = 4', corresponding to answer choice C).
Explanation:To solve the system of equations:
a + b = 10a - b = 2We can add the two equations to eliminate the variable b. By adding them, we get:
2a = 12
Divide both sides of the equation by 2:
a = 6
With the value of a known, substitute a = 6 into either of the original equations. For example, substituting it into the first equation:
a + b = 10
6 + b = 10
b = 10 - 6
b = 4
Therefore, the solution to the system of equations is a = 6 and b = 4, which corresponds to answer choice C).
if 4x + 2 equals 4 what is the value of 2x + 1
To find the value of 2x + 1, we first solved for x in the equation 4x + 2 = 4, which yielded x = 1/2. Substituting this value into 2x + 1, the final answer is 2.
Explanation:The question seeks a solution for the value of 2x + 1 given that 4x + 2 = 4. We start by solving for x in the initial equation. Subtract 2 from both sides to get 4x = 4 - 2, which simplifies to 4x = 2. Dividing both sides by 4 yields x = 2 / 4, which simplifies to x = 1/2. Now that we have the value of x, we substitute it into the expression 2x + 1. So, 2(1/2) + 1 equals 1 + 1, which equals 2.
To find the value of 2x + 1, we need to determine the value of x first. Given that 4x + 2 = 4, we can start by subtracting 2 from both sides to isolate the 4x term. This gives us 4x = 2. Next, we divide both sides by 4 to solve for x. So x = 2/4 = 1/2.
Now that we know the value of x, we can substitute it into the expression 2x + 1. Plugging in x = 1/2, we get 2(1/2) + 1 = 1 + 1 = 2.
Therefore, the value of 2x + 1 is 2.

The value of x is [tex]\frac{3a}{4b}[/tex] and [tex]-\frac{2b}{3a}[/tex]
Explanation:
The expression is [tex]12abx^{2} -(9a^{2} -8b^{2} )x-6ab=0[/tex]
Multiplying the term x withing the bracket, we get,
[tex]12abx^{2} -9a^{2} x+8b^{2} x-6ab=0[/tex]
Grouping the terms, we have,
[tex](12abx^{2} -9a^{2} x)+(8b^{2} x-6ab)=0[/tex]
Taking out the common terms in each bracket, we get,
[tex]3ax(4bx -3a)+2b(4bx-3a)=0[/tex]
Simplifying, we get,
[tex](3ax+2b)(4bx -3a)=0[/tex]
Equating each term to zero, we get,
[tex]\begin{aligned}3 a x+2 b &=0 \\3 a x &=-2 b \\x &=-\frac{2 b}{3 a}\end{aligned}[/tex] and [tex]\begin{aligned}4 b x-3 a &=0 \\4 b x &=3 a \\x &=\frac{3 a}{4 b}\end{aligned}[/tex]

12 years ago left it was twice as old as Hester Lester is 21 years older than Hester what would be the sun in 5
Answer:
The sum of their ages in 5 years will be 97 years
Step-by-step explanation:
The correct question is
Twelve years ago, Lester was twice as old as Hester. Lester is 21 years older than Hester. What will the sum of their ages be in 5 years?
Let
x ----> Lester's age
y ----> Hester's age
we know that
Twelve years ago, Lester was twice as old as Hester
so
[tex]x-12=2(y-12)[/tex]
[tex]x-12=2y-24[/tex]
[tex]x-2y=-12[/tex] ----> equation A
Lester is 21 years older than Hester
so
[tex]x=y+21[/tex] ----> equation B
substitute equation B in equation A
[tex]y+21-2y=-12[/tex]
solve for y
[tex]-y=-12-21\\-y=-33\\y=33[/tex]
Find the value of x
[tex]x=33+21=54[/tex]
therefore
Lester's age is 54 years and Hester's age is 33 years
The sum of their ages in 5 years will be
[tex](54+5)+(33+5)=97\ years[/tex]
How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?
Answer:
The number of 1/5 liter glasses that Lin can fill is [tex]7\frac{1}{2}[/tex]
Step-by-step explanation:
we know that
To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5
so
[tex]1\frac{1}{2} :\frac{1}{5}[/tex]
Convert mixed number to an improper fraction
[tex]1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}[/tex]
substitute
[tex]\frac{3}{2} :\frac{1}{5}[/tex]
Multiply in cross
[tex]\frac{5*3}{2*1}=\frac{15}{2}=7.5[/tex]
Convert to mixed number
[tex]7.5=7+\frac{1}{2}=7\frac{1}{2}[/tex]
Lin can fill 7.5 glasses of water from a 1 1/2 liter bottle. However, if only full glasses are counted, Lin can fill 7 full glasses.
Explanation:The question asks how many 1/5 liter glasses can be filled with a 1 1/2 liter bottle of water. To answer this, we need to perform a division of the total volume of the water by the volume of each glass.
First, express both quantities in the same units, in liters. The bottle has 1 1/2 liters, which is the same as 1.5 liters. Now, divide the total volume of the water by the volume of one glass:
1.5 liters / (1/5 liter per glass) = 1.5 * 5 = 7.5 glasses.
Therefore, Lin can fill 7.5 glasses of water from a 1 1/2 liter bottle, if we consider that partial glasses can be filled. If only full glasses can be filled, Lin can fill 7 full glasses.

Ben bowled 121 and 184 in his first two games. What must he bowl in his third game to have an average of at least 170?
Answer:
205
Step-by-step explanation:
Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.
For Ben to have an average of at least 170 in his third game, he must bowl a score of 205.
Explanation:To find out what Ben must bowl in his third game to have an average of at least 170, we can use the formula for average: average = total score/number of games.
In this case, Ben has played two games and wants to have an average of 170. So we can set up the equation: 170 = (121 + 184 + x) / 3, where x represents his score in the third game.
To solve for x, we can multiply both sides of the equation by 3 to get rid of the fraction: 510 = 121 + 184 + x.
Then, we can combine the numbers on the right side: 510 = 305 + x.
Finally, subtracting 305 from both sides gives us: 205 = x.
Therefore, Ben must bowl a score of 205 in his third game to have an average of at least 170.
