Jan's age = [tex] 4\frac{5}{6}[/tex] years
Sister's age =[tex] 9\frac{2}{3} \: years[/tex]
Step-by-step explanation:
Jan's age = x years
Sister's age = 2x years
Brother's age = 3x years
According to the given condition:
x + 2x + 3x = 29
6x = 29
x = 29/6
x = [tex] 4\frac{5}{6}[/tex] years
2x = [tex] 2\times \frac{29}{6}= \frac{29}{3}=9\frac{2}{3} \: years[/tex]
Therefore,
Jan's age = [tex] 4\frac{5}{6}[/tex] years
Sister's age =[tex] 9\frac{2}{3} \: years[/tex]

The population of Tel Aviv, Israel was 413,000 in 2003. What is 413,000 rounded to ther nearest hundred-thousand?
Answer:
400,000
Step-by-step explanation:
Tel Aviv Population (2013) - 413,000
413,000 rounded to nearest hundred-thousand = 400,000
Final sum= 400,000. Hope this helps!
Answer: 400,000
The population of Tel Aviv in 013 was 413,000.
We have to round this number to the nearest 100,000.
We get 400,000, so it is the answer.
How many coins are in one pouch? Post the strategies you used to find the other number of coins in one pouch.
Answer:
6
Step-by-step explanation:
First, make an equation out of this diagram. Replace the coin pouches with the variable of x, and replace the number of coins with numerical values. You get the equation 2x + 21 = 5x + 3. Subtract 3 from both sides to get 2x + 18 = 5x. Then, subtract 2x from both sides to get 3x = 18. Divide both sides by 3 to get 6 coins per pouch.

Which description is true about pre-image ABC and image A′B′C′ ?
A.) The image is a rotation of the pre-image clockwise at 90°.
B.) The image is a reflection of the pre-image across the y-axis.
C.) The image is a dilation of the pre-image with a scale factor or 3.
D.) The image is a translation of the pre-image by moving up 2 units and to the right 2 units.
Answer:
Option (C)
Step-by-step explanation:
From the graph attached,
In ΔABC and ΔA'B'C',
∠A ≅ ∠A'
∠B ≅ ∠B'
Therefore, ΔABC ~ ΔA'B'C'
Corresponding sides of these triangles will be proportional.
[tex]\frac{\text{AB}}{\text{A'B'}}=\frac{\text{BC}}{\text{B'C'}}=\frac{\text{AC}}{\text{A'C'}}=\frac{2}{6}[/tex]
Therefore, ratio of the sides, AC : A'C' = 1 : 3 shows that image triangle A'B'C' is a dilated form of pre-image ABC with a scale factor of 3.
Option (C) will be the correct option.

I don’t get it! It says “Match each division expression to it’s quotient.” So can anyone help with 1/12 / 1/6 ? Please!
We have two fractions being divided. When we divide two fractions, we flip the second fraction and multiply
1/12 divided by 1/6 = 1/12 * 6/1
-------
From here we multiply straight across.
The numerators multiply to get 1*6 = 6
The denominators multiply to 12*1 = 12
We end up with 6/12 which reduces to 1/2 when you divide both parts by the GCF 6
Final Answer: 1/2
A triangle has sides with lengths of 5x-7,

the triangle
A 10x-17
B 6x-17
C 4x-9
D -7x
Answer:
A. 10x -17
Step-by-step explanation:
5x-7, 3x-4, and 2x-6.
combine like terms
5x-7 + 3x-4 + 2x-6
5x + 3x + 2x - 7 -4 - 6
10x -17
therefore the answer is A. 10x -17

the larger of two numbers is 4 more than the smaller the sum of the two numbers is 74
Answer:
y = 35 x = 39
Step-by-step explanation:
Let large no = x and small no = y
According to the question,
x = 4 + y ------ (1)
x + y = 74 -------- (2)
Substituting (1) in (2)
( 4 + y ) + y = 74
4 + 2y= 74
2y = 74 -4
y = 70 / 2 = 35
x = 4 + y
= 4 + ( 35 )
= 39

A dish containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10−16 kilometer. How many times larger is the diameter of the dish than the diameter of the bacterium?
Answer:
100000000000 times
Step-by-step explanation:
Given
Diameter of Dish = 0.00001 km
Diameter of Bacterium = 10⁻¹⁶ km
Required
Determine the number of times the diameter of dish is bigger than that of the bacterium
To solve this, we simply divide the diameter of dish by the diameter of the bacterium as follows
[tex]Ratio = \frac{Dish}{Bacterium}[/tex]
[tex]Ratio = \frac{0.00001}{10^{-16}}[/tex]
[tex]Ratio = 100000000000[/tex]
Hence, the diameter of the dish is 100000000000 times larger than the diameter of the bacterium

Plot A(−3,−1), B(−3,2), C(6,9), and D(3,9) in a coordinate plane. Are AB¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯ congruent? Yes No
Answer:
Yes
Step-by-step explanation:
The given points are A(−3,−1), B(−3,2), C(6,9), and D(3,9).
Plot these points on a coordinate plane as shown in the below graph.
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using this formula, we get
[tex]AB=\sqrt{(-3-(-3))^2+(2-(-1))^2}[/tex]
[tex]AB=\sqrt{(0)^2+(3)^2}[/tex]
[tex]AB=3[/tex]
[tex]CD=\sqrt{(3-6)^2+(9-9)^2}[/tex]
[tex]CD=\sqrt{(-3)^2+(0)^2}[/tex]
[tex]CD=3[/tex]
Since AB=CD, therefore the required answer is yes, AB and CD are congruent.
59. What happens to the graph of y = |x| when the equation changes to y = |x + 4? A The graph shifts up 4 units. The graph shifts left 4 units. B с The graph shifts right 4 units. D The graph shifts down 4 units.
Answer: Graph shifts 4 units to the left
Explanation:
I'm assuming you meant to say y = |x+4|
If so, then the graph shifts 4 units to the left. Replacing x with x+4 moves the xy axis 4 units to the right if we held the V shape in place (since each x is now 4 units larger). This gives the illusion the V shape is moving 4 units to the left.
Or you could look at the vertex point to see how it moves. On y = |x|, the vertex is at (0,0). It then moves to (-4,0) when we go to y = |x+4|
Mary has 60 candy pieces and 45 chocolates. She wants to distribute the candy to her little sister's friends at her birthday party so that each friend gets an equal number of candies and an equal number of chocolates.What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over
Answer:
5 friends
Step-by-step explanation:
Candy pieces = 60
Chocolate = 45
What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over?
To calculate this, find the lowest factor of 60 and 45
60:
Factors = 2, 4, 5, 6,
45:
Factors= 3, 5, 9
The lowest common factor of 60 and 45 is 5
The smallest number of her sister's friend so each person get an equal number of candy pieces and chocolate so there won't be any leftover is 5
That is
If there are 5 friends at the birthday party
60 candy pieces among 5 friends
= 60/5
= 12 pieces each
45 chocolate among 5 friends
= 45/5
= 9 each
