Joaquin is four more than half Marjorie’s age. Marjorie is also 32 less than three times Joaquin’s age.
How old is Marjorie?
Answers
Answer:
She is 40 years of age
Step-by-step explanation:
Let Joaquin age be j
Let Marjorie age be m
From the first part of the question;
j = 4 + m/2
Secondly;
m =3j - 32
Multiply equation i through by 2
2j = 8 + m
m = 2j-8
Equate both m
2j-8 = 3j-32
3j-2j = 32 -8
j = 24
m = 2j-8
m = 2(24)-8
m = 48-8
m = 40

Step-by-step explanation:
Identify the two factors that were multiplied together to form the array of tiles. Then identify the product of the two factors. Use the variable x in your expressions.
Answers
Answer:
[tex]Terms: 3\ and\ x + 2[/tex]
[tex]Product = 3x + 6[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, there are 3 columns and 3 rows
The 3 columns represent the first factor
To get the second factor, we have to analyze the 3 rows in the attachment.
Notice that the first row is bigger than the other two rows.
This big row will be represented with variable x
Notice that the boxes in second row are smaller than the first row and the + sign is written on each of the boxes.
This is represented with + 1
Also, notice that the boxes in third row are smaller than the first row and the + sign is written on each of the boxes.
This is also represented with + 1
Hence, the expression for the rows is x + 1 + 1 = x + 2
The product is then calculated as:
[tex]Product = 3 * (x + 2)[/tex]
[tex]Product = 3 * x + 3*2[/tex]
[tex]Product = 3x + 6[/tex]
The height of a pebble dropped from a cliff 20,00 feet heigh is described by formula h(t)=20,000 + 5t^2. How long will the pebble take to reach a height of 32,500 feet?
Answers
Answer:
It will take 50 seconds for the pebble to reach the height
Step-by-step explanation:
To calculate the time, simple substitute h(t) for 32,500
So we have
32,500 = 20,000 + 5t^2
5t^2 = 32,500-20,000
5t^2 = 12500
t^2 = 12500/5
t^2 = 2500
t = square root of 2500
t = 50 seconds

Triangles DEF and GHI are shown. Which sequence of rotations, reflections, and/or translations would map triangle DEF onto triangle GHI?
Does mapping triangle DEF onto triangle GHI prove the two triangles are congruent? Explain your reasoning.
Answers
Answer:
Part A:
The sequence of transformation that maps triangle DEF to triangle GHI are;
1) A reflection across the y-axis (x, y) →(-x, y) and
2) A translation 6 units down, (-x, y - 6)
Part B:
1) Yes
2) The points of the triangle GHI obtained from the mapping of triangle DEF using the given transformation are corresponding therefore, the mapping proves that the two triangles are congruent
Step-by-step explanation:
Part A:
The given coordinates of the vertices of triangle DEF are;
F(-1, 5), D(-5, 2), and E(-3, 1)
The given coordinates of the vertices of triangle IHG are;
I(1, -1), H(3, -5), and G(5, -4)
Therefore, the transformation that maps ΔDEF to ΔGHI are
1) A reflection across the y-axis (x, y) →(-x, y) and
2) A translation 6 units down, (-x, y - 6)
Reflection of point F(-1, 5) across the y-axis gives → (1, 5)
Followed by a translation 6 units down gives;
(1, 5) →T(y - 6) → I(1, -1)
Reflection of point D(-5, 2) across the y-axis gives → (5, 2)
Followed by a translation 6 units down gives;
(5, 2) →T(y - 6) → G(5, -4)
Reflection of point E(-3, 1) across the y-axis gives → (3, 1)
Followed by a translation 6 units down gives;
(3, 1) →T(y - 6) → H(3, -5)
Part B:
1) Yes mapping triangle DEF onto triangle GHI proves that the two triangles are congruent
2) The points of the triangle GHI obtained from the mapping of triangle DEF are the same, therefore, the mapping proves that the two triangles are congruent

Sabeena’s pen measures 144 millimeters long. Her pencil measures 18 centimeters long. How many centimeters longer is Sabeena’s pencil than her pen?
Enter the correct answer in the box.
Answers
Answer:
3.6 cm or 36mm
Step-by-step explanation:
So we know that there are 10 millimetres in a centimetre. So we can convert the 18cm into millimetres to make it easy to subtract
18cm*10=180mm
now take the pencil length subtracted by the length of the pen.
180mm-144mm=36mm
now if you want the answer in cm, convert it by dividing the answer by 10
36/10=3.6cm
Hope This Helps :)
Answer:3.6 cm
