Leila bought 3 bananas, which weighed a total of Three-fourths of a pound. If each banana weighed the same amount, what is the weight of each banana? StartFraction 1 Over 12 EndFraction of a pound StartFraction 1 Over 9 EndFraction of a pound One-fourth of a pound One-third of a pound
Answer:
[tex]Each\ Weight = \frac{1}{4}[/tex]lb
Step-by-step explanation:
Given
[tex]Weights = \frac{3}{4}lb[/tex]
[tex]Bananas = 3[/tex]
Required
Determine the weight of each
To do this, we simply divide the total weight by the number of bananas.
[tex]Each\ Weight = \frac{3}{4}/3[/tex]
Convert to multiplication
[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]
[tex]Each\ Weight = \frac{1}{4}[/tex]
Hence, each banana weighs 1/4 of a pound

2(3v-5)=2(v-11)-4 can someone help me out ?
Answer:
v = -4
Step-by-step explanation:
2(3v - 5) = 2(v - 11) - 4
6v - 10 = 2v - 22 - 4
+10 +10
6v = 2v -12 - 4
-2v -2v
4v = -16
divide both sides by 4
v = -4
Hope this helps!!
The value of v = - 4.
We have the following equation -
2(3v - 5) = 2(v - 11) - 4
We have to find out the value of the variable v.
What is the solution of a equation in one variable?The solution of an equation is the value of variable for which the left hand side is equal to right hand side.
We have the following equation -
2(3v - 5) = 2(v - 11) - 4
2 x 3v - 2 x 5 = 2v - 2 x 11 - 4
6v - 10 = 2v - 22 - 4
6v - 10 = 2v - 26
6v - 2v = - 26 + 10
4v = -16
v = - 4
Hence, the value of v = - 4.

According to the National Oceanic and Atmospheric Administration, the blue whale is the largest animal on Earth. Blue whales weigh approximately 3×105 pounds. Narwhals, which are also a type of whale, weigh approximately 2×103 pounds. How many times heavier is the blue whale's weight than the narwhal's weight?
Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.
Step-by-step explanation:
Given: Weight of Blue whale = [tex]3\times10^5\text{ pounds}[/tex]
Weight of Narwhal = [tex]2\times10^3\text{ pounds}[/tex]
Number of times blue whale's weight is heavier than the narwhal's weight = [tex]=\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}[/tex]
[tex]=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150[/tex]
Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

The measure of the exterior angle of the triangle is
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
2x - 2 = 45 + x
2x - x = 45 + 2
x = 47°
Answer:
x = 47
Step-by-step explanation:
Finding the third angle (y) of the triangle:
- Since angles on a straight line add up to 180:
2x -2 + y = 180
y = -2x + 2 + 180
= -2x + 182
Hence, the third angle of the triangle is -2x + 182.
Since all 3 angles of a triangle add up to 180°:
-2x + 182 + x + 45 = 180
-2x + x + 227 = 180
-2x + x = 180 - 227
-x = -47
x = 47
Hence, x = 47

Natalia is writing a recursive formula to represent the sequence.
8, 12, 18, 27, ...
What value should she use as the common ratio in the formula?
1/4, 2/3, 3/2, 4/1
Answer:
The answer to your equation would be 1.5.
Step-by-step explanation:
The common ratio if there exists one can be found by choosing a term and dividing by its previous term
So does 12/8=18/12=27/18? Put each into the calculator. If they are equal fractions then this sequence is geometric and has a common ratio.
Each of the fractions are equal to 1.5.
Therefore the commom ratio is 1.5.

Tim thinks that the following expression will only yield values that are positive. x^2
Is Tim correct? Explain why or why not and provide three examples that prove whether Tim’s statement is correct.
Answer:
We conclude that Tim is correct when he says that the expression x² only yields values that are positive.
Step-by-step explanation:
Given the expression
x²
Plug in and checking x = 1 and x = -1 in the expressionPutting x = 1 in the expression
x²= (1)² = 1
Putting x = -1 in the expression
x²= (-1)² = 1
Thus, the expression yields the same output '1' when we enter x = 1, and x=-1.
Plug in and checking x = 2 and x = -2 in the expression
Putting x = 2 in the expression
x²= (2)² = 4
Putting x = -1 in the expression
x²= (-2)² = 4
Thus, the expression yields the same output '4' when we enter x = 2, and x=-2.
Plug in and checking x = 3 and x = -3 in the expressionPutting x = 3 in the expression
x²= (3)² = 9
Putting x = -1 in the expression
x²= (-3)² = 9
Thus, the expression yields the same output '9' when we enter x = 3, and x=-3.
The reason why the expression x² only yields positive values because the expression is in the square form, and the square of any number will always yield a positive value, no matter whether the input number is negative or positive.
Therefore, we conclude that Tim is correct when he says that the expression x² only yields values that are positive.

In ΔCDE, \text{m}\angle C = (5x+18)^{\circ}m∠C=(5x+18) ∘ , \text{m}\angle D = (3x+2)^{\circ}m∠D=(3x+2) ∘ , and \text{m}\angle E = (x+16)^{\circ}m∠E=(x+16) ∘ . Find \text{m}\angle D.M∠D.
Answer:
Angle D = m∠D= 50°
Step-by-step explanation:
In ΔCDE we are given: 3 angles
m∠C=(5x+18) ∘
m∠D=(3x+2) ∘
m∠E=(x+16) ∘ .
The sum of angles in a triangle = 180°
Hence:
m∠C + m∠D + m∠E = 180°
(5x+18)° + (3x+2)° + (x+16)° = 180°
5x + 18 + 3x + 2 + x + 16 = 180°
5x + 3x + x + 18 + 2 + 16 = 180°
9x +36= 180°
Subtract 36 from both sides
9x + 36 - 36 = 180° - 36°
9x = 144°
x = 144°/9
x = 16
From the above question, we are asked to find:angle D (m∠D )
Hence:
m∠D=(3x+2)°
m∠D=( 3 × 16 + 2)°
m∠D=(48 + 2)°
m∠D= 50°
A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 202020 meters wide by 404040 meter long rectangle. The company already has 100100100 meters of tape. How much more tape does the company need to tape the site?
Answer:
20 meters
Step-by-step explanation:
A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?
We would have to find the perimeter of this rectangle
Perimeter fo a rectangle = 2L + 2W
In the above question,
L = Length = 40 m
W = Width = 20 m
Hence:
Perimeter = 2(40m) + 2(20m)
= 80m + 40m
= 120m
Hence, he would need 120 meters of tape
From the above Question, the company already has 100m
Hence, the amount of tape that the company needs more =
120m - 100m = 20 m

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply
Answer:
When x=2, both expressions have a value of 18.
The expressions have equivalent values for any value of x.
The expressions have equivalent values if x=8
Step-by-step explanation:
James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
7x + 4
= 7(2) + 4
= 14 + 4
= 18
3x + 5 + 4x - 1
3(2) + 5 + 4(2) - 1
6 + 5 + 8 - 1
= 18
The expressions are only equivalent for x = 4 and x = 6.
• This is not true because the expression is also equivalent for x = 2
The expressions are only equivalent when evaluated with even values.
When x = 1
7x + 4
7(1) + 4
= 7 + 4
= 11
3x + 5 + 4x - 1
3(1) + 5 + 4(1) - 1
3 + 5 + 4 - 1
= 11
The expressions have equivalent values for any value of x.
Yes, it has an equivalent value at any value of x
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
7x + 4
7(0) + 4
= 0 + 4
= 4
3x + 5 + 4x - 1
3(0) + 5 + 4(0) - 1
0 + 5 + 0 -1
= 4
The expressions have equivalent values if x = 8.
7x + 4
7(8) + 4
56 + 4
= 60
3x + 5 + 4x - 1
3(8) + 5 + 4(8) - 1
24 + 5 + 32 - 1
= 60

Triangle ACB with coordinates A(0,0), C(2,0), and B(2,4) is similar to triangle BED. If vertex D has coordinates (6,12), what are the coordinates of vertex E?
Answer:
A right triangle is a triangle that has 90 degrees angle in one of its parts. You are given two points that have coordinate:
x1,y1= (-2, 4)
x2,y2= (-1,1)
To make the angle 90 degrees, there is two possible third point coordinate:
1. x1, y2 = (-2,1)
2. x2, y1= (-1,4)
The right triangle would be option C: (-2,1)
Option A and B is not a right triangle
Step-by-step explanation:
Answer:
the coordinates of vertex E is (6,0)
C(2,0),compare this to(2,4)
same x.but y=0
(6,0)comparing to (6,12)
we get it
