How much surface area would be lost if you glued three 4-cm cubes together to make a rod that is three cubes long and one cube wide?
Answers
Answer:
Part 3) [tex]SA=288\ cm^2[/tex]
Part 4) [tex]64\ cm^2[/tex]
Step-by-step explanation:
Part 3) Calculate the total surface area of three 4 cm cubes
we know that
The surface area of a cube is equal to the area of its six square faces
[tex]SA=6b^2[/tex]
so
The surface area of three cubes is equal to the area of its 18 square faces
[tex]SA=18b^2[/tex]
where
b is the length side of the square face
In this problem
[tex]b=4\ cm[/tex]
so
The surface area of three cubes is
[tex]SA=18b^2[/tex]
substitute the given value
[tex]SA=18(4)^2[/tex]
[tex]SA=288\ cm^2[/tex]
Part 4) How much surface area would be lost if you glued three 4-cm cubes together to make a rod that is three cubes long and one cube wide?
In this case the total surface area of the three glued 4-cm cubes is equal to the area of its 14 square faces
so
The surface area lost is equal to
[tex]18b^2-14b^2=4b^2[/tex]
substitute
[tex]4(4)^2=64\ cm^2[/tex]
Gluing three 4-cm cubes together to form a rod results in a loss of 64 cm²of surface area because the areas of the glued faces are no longer exposed.
Each individual cube has 6 faces, so the surface area of one cube is 6 times the area of one face. With a side length of 4 cm, the area of one face is 4 cm imes 4 cm = 16 cm². Thus, the total surface area for one cube is 6 imes 16 cm²= 96 cm². For three separate cubes, this would be 3 imes 96 cm² = 288 cm².
When the three cubes are glued together side by side to form a rod, they share faces. Each glue contact removes two faces worth of area (one from each cube). As there are two glue contacts, a total of 4 faces are lost. Therefore, the lost surface area is 4 imes 16 cm2 = 64 cm².
The original total surface area was 288 cm², so the new surface area after gluing is 288 cm² - 64 cm² = 224 cm². Hence, gluing the cubes together results in a loss of 64 cm² of surface area.

The isosceles trapezoid is part of an
isosceles triangle with a 46° vertex angle.
Enter the measure of an acute base angle of
the trapezoid.
Answers
Final answer:
Using the properties of isosceles triangles, the acute base angle of the isosceles trapezoid, which is part of an isosceles triangle with a 46° vertex angle, is found to be 67°.
Explanation:
To find the measure of an acute base angle of the isosceles trapezoid that is part of an isosceles triangle with a 46° vertex angle, we can apply the properties of isosceles triangles. By the Isosceles Triangle Theorem, we know that the angles opposite the equal sides are equal.
Since the given triangle is isosceles, the two base angles must also be equal. Additionally, we know that the sum of all angles in any triangle is 180°.
Let's call each of the base angles B. Then, the sum of all angles in the triangle is:
46° + B + B = 180°
Now we solve for B:
2B = 180° - 46° = 134°
B = 134° / 2 = 67°
Thus, each base angle of the isosceles triangle is 67°. Next, considering the isosceles trapezoid, we know the adjacent angles must be supplementary because they are on the same line. This means that one base angle of the isosceles trapezoid equals:
180° - 67° = 113°
However, since the student is looking for the measure of an acute base angle of the trapezoid and 113° is an obtuse angle, the acute base angle is the original 67° angle that we found. This is because the acute and obtuse angles in the trapezoid are adjacent angles around the same vertex, and the acute angle is the angle that's interior to the triangle.
Therefore, the measure of an acute base angle of the trapezoid is 67°.

At the start of the month, Jodie had sold 885 copies of her new book. At the end of the month, she had sold 1,364 copies of her book. If each book profits $13.97, approximately how much did the book profit in the entire month?
Answers
Approximately $ 31419 profit is earned from selling books in entire month
Solution:
Given that Jodie had sold 885 copies of her new book
At the end of the month, she had sold 1,364 copies of her book
We have to determine the profit earned in the entire month
From given information,
Start of month sale = 885 copies
End of month sale = 1364 copies
Total copies of books sold = Start of month sold + end of month sold
Total copies of books sold = 885 + 1364 = 2249
Also given that each book profit is $ 13.97
Profit of 1 book = $ 13.97
Therefore for 2249 books, profit earned is given as:
Profit of 2249 books = $ 13.97 x 2249 = 31418.53
Therefore approximately $ 31419 profit is earned from selling books in entire month
Abby bought two slices of pizza and two bottles of water for $7.25 Cameron bought four slices of pizza and one bottle of water for $8.25 what is the solutionm
Answers
The solution is price of 1 slice of pizza is $ 1.542 and price of 1 bottle of water is $ 2.083
Solution:
Let "p" be the price of 1 slice of pizza
Let "b" be the price of 1 bottle of water
Given that Abby bought two slices of pizza and two bottles of water for $7.25
So we can frame a equation as:
two slices of pizza x price of 1 slice of pizza + two bottles of water x price of 1 bottle of water = $ 7.25
[tex]2 \times p + 2 \times b = 7.25[/tex]
2p + 2b = 7.25 ---- eqn 1
Also given that Cameron bought four slices of pizza and one bottle of water for $8.25
So we can frame a equation as:
four slices of pizza x price of 1 slice of pizza + one bottles of water x price of 1 bottle of water = $ 8.25
[tex]4 \times p + 1 \times b = 8.25[/tex]
4p + b = 8.25 ---- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "p" and "b"
Multiply eqn 2 by 2
8p + 2b = 16.5 --- eqn 3
Subtract eqn 1 from eqn 3
8p + 2b = 16.5
2p + 2b = 7.25
(-) ----------------------
6p = 9.25
p = 1.542From eqn 1,
2p + 2b = 7.25
2(1.542) + 2b = 7.25
2b = 4.166
b = 2.083Thus price of 1 slice of pizza is $ 1.542 and price of 1 bottle of water is $ 2.083

Answer:
is it 8 apples to her mother or 10 since I had this exact problem?
Step-by-step explanation:
Ashe started with 32 apples in the basket initially.
How to find half of something ?To find the half of something just multiply 1/2 with the given value.
According to the given question Linda picked a basket of apples.
Assuming she had x apples initially.
She gave half of the apples to the neighbour,Therefore she now has (x - 1/2x) apples which is = 1/2x apples.
Then she gave 10 to her mother,So the remaining apples she has now is
= ( 1/2x - 10 ) apples
= (x - 20)/2.
Then she gave half of the apples to her best friend so the no. of apples she has now is (x - 20)/2×1/2 which is = (x - 20)/4 and she kept the remaining 3.
∴ (x - 20)/4 = 3

The sum of Ava’s and Grace’s age is 35. Ava is one year less than three times Grace’s age. How old is Grace?
Answers
Grace is 9 years old. We found this by setting up a system of equations with the information given and solving for Grace's age.
Explanation:We are given two pieces of information about Ava and Grace's ages:
The sum of Ava’s and Grace’s age is 35.Ava is one year less than three times Grace’s age.To find Grace’s age, we can set up a system of equations based on the information provided:
Let G represent Grace’s age.Let A represent Ava’s age.The first equation can be written as:
A + G = 35
From the second piece of information, we can write:
A = 3G - 1
Now, we can substitute the expression for A into the first equation:
3G - 1 + G = 35
Combine like terms:
4G - 1 = 35
Add 1 to both sides:
4G = 36
Divide by 4:
G = 9
So, Grace is 9 years old.

Let Miguel buy D DVDs. Each costing 10.99, that would make the cost:
10.99D
Shipping cost entire order is 9.99, so this would be added to DVD cost. Total cost:

This total cost can be NO MORE THAN 100, so this expression would be equal to or less than 100, so we can write:
[tex]10.99D + 9.99 \leq 100[/tex]

[tex]10.99D \leq 90.01[/tex]
First choice is correct.
Second choice, clearly, isn't correct.

Answers
The expression √215x should be further simplified for (a) 35 as the value of x
How to determine the value of x
From the question, we have the following parameters that can be used in our computation:
√215x
Taking each value of x from the list of options, we have
√215x = √(215 * 35)
Expanding, we get
√215x = √(5 * 43 * 7 * 5)
This gives
√215x = 5√301
Next, we have
√215x = √(215 * 118)
Expanding, we get
√215x = √(5 * 43 * 2 * 59)
This gives
√215x = √(25370)
Next, we have
√215x = √(215 * 34)
Expanding, we get
√215x = √(5 * 43 * 2 * 17)
This gives
√215x = √7310
Next, we have
√215x = √(215 * 7)
Expanding, we get
√215x = √(5 * 43 * 7)
This gives
√215x = √1505
Hence, the value of x is 35

For x=2, y=-9
substitute in the linear equation
[tex]5(2)-\frac{(-9)}{3}=13[/tex]
[tex]10-(-3)=13[/tex]
[tex]10+3=13[/tex]
[tex]13=13[/tex] ----> is true
so
The ordered pair satisfy the equation
The ordered pair is a solution of the equation
Verify the second ordered pair
Part b) we have (3,-6)
For x=3, y=-6
substitute in the linear equation
[tex]5(3)-\frac{(-6)}{3}=13[/tex]
[tex]15-(-2)=13[/tex]
[tex]15+2=13[/tex]
[tex]17=13[/tex] ----> is not true
so
The ordered pair not satisfy the equation
The ordered pair is not a solution of the equation

Step-by-step explanation:
solve the equation -t = 9(t-10)−t=9(t−10)
Answers
Answer:
Infinitely many solutions.
Step-by-step explanation:
-t=9(t-10)-t=9(t-10)
-t=9t-90-t=9t-90
-t=8t-90=9t-90
8t-(-t)-90=9t-90
8t+t-90=9t-90
9t-90=9t-90
Answer:
If you mean −t=9(t−10), then the answer is 9, if you mean −t=9(t−10)−t=9(t−10) then infinite solutions.
Step-by-step explanation:
Here is the answer if you mean −t=9(t−10):
−t = 9 (t−10)
Simplify the equation.
-t = (9)(t) + (9)(-10)
-t = 9t + -90 (Add the opposite)
-t = 9t - 90
Subtract -9t
-t -9t = 9t - 90 - 9t
-10t = - 90
Divide -10 on both sides to make sure the equation is balanced on both sides. And to isolate t to get the final answer.
-10t = -90
-10t = -10
Therefore,
t = 9Is the final answer.
