Trying to factor by splitting the middle term
3.1 Factoring 9v2-9v-1
The first term is, 9v2 its coefficient is 9 .
The middle term is, -9v its coefficient is -9 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 9 • -1 = -9
Step-2 : Find two factors of -9 whose sum equals the coefficient of the middle term, which is -9 .
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Sydney has 3 3/5 yards of ribbon to make bows. Each bow is made from a piece of ribbon that is 2/5. How many bows can Sydney make?
Answer:
9
Step-by-step explanation:
2/5 x 2 = 4/5
4/5 x 2, or 2/5 x 4 = 1 3/5
1 3/5 x 2, or 2/5 x 8 = 3 1/5
3 1/5 + 2/5, or 2/5 x 9 = 3 3/5
A house has increased in value by 35% since it was purchased. If the current value is $297,000, what was the value when it was purchased?
Answer:
Answer:
$260,000
Step-by-step explanation:
Explanation:
Given the problem above, we solve for original value
Hence, in this case, we are given
percentage (35%) and the New Value ($351,000).
We can substitute this into the formula and solve for X
Let X be the original price, Hence, X = 100%
Therefore, $351000 = 135%
Divide both sides by 135
351000÷ 135 = 135÷135
2600 = 1%
Multiply both sides by 100
2600 * 100 = 1% * 100
$260000 = 100% = X
Hence, final answer is $260000

James has collected 3985 stamps so far. He had 787 stamps from countries other than the United States. What percent of the stamps are from countries other than the United States?
Answer:
divide 787 by 3985 then multiply that by 100
Step-by-step explanation:
if it were 100 stamps total and 50 from non US countries, you could pretty easily tell it was half, or 50% to ge that you need to divide the number in question by the total so 50/100. which gets .5. to get the percent you multiply it by 100
so given the numbers we divide 787 by 3985 then multiply that by 100

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
You leaned the ladder against your house at a 30° angle of elevation.
And, The foot of the ladder is 7 feet from the foot of the house.
Now,
Let the length of ladder = x
Hence, We can formulate;
⇒ cos 30° = 7 / x
⇒ √3 / 2 = 7 / x
⇒ x = 14 / √3 feet
Thus, The length of ladder would be,
⇒ 14/√3 feet

Shaun is 1.88 m tall.
David is 6 cm taller than Shaun.
How tall is David
David is 1.94 meters tall.
Given that,
Shaun is 1.88 meters tall.
David is stated to be 6 centimeters taller than Shaun.
To determine David's height, we need to add the additional height to Shaun's height.
Since there are 100 centimeters in a meter, we can convert the 6 centimeters to meters by dividing it by 100: 6 cm / 100 = 0.06 meters.
Now, we can add this height to Shaun's height to find David's height:
1.88 meters + 0.06 meters = 1.94 meters.
Therefore, David is 1.94 meters tall.

Least the containers from least to greatest capacity; 1.73, 2.061, 1.59, 2.1
Answer:
1.59 < 1.73 < 2.061 < 2.1
Step-by-step explanation:
Hello,
We know that 2 is higher than 1. So to pick the first ones we know it won't be the two numbers starting with a 2. We are left with two numbers : 1.73 and 1.59. In this case we can multiply these two numbers by 100. We are allowed to do this only if we do it to all the numbers we are trying to figure out. In this case, it is 1.73 and 1.59 (we are excluding the 2s). So we end up with : 173 and 159. This might help you. We obviously know that 173 is a larger number than 159.
So, we then proceed to the numbers starting with a 2. In this case we can multiply both by 1,000 considering the fact that the number 2.061 has 3 digits after the dot. This will make it easier for us. When we multiply both by 1,000 we end up with 2,061 and 2,100. We obviously know that 2,061 is smaller than 2,100.

What is the length of a diagonal of a square with a side length of 8?
A. 4
B. 42
C. 43
D. 82
Answer:
D. 8[tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the diagonal of the square, you can use the Pythagorean theorem* to find the hypotenuse since the diagonal cuts the square into two right triangles with legs of 8 units in length:
If in a^2 + b^2 = c^2, a = 8 and b = 8,
8^2 + 8^2 = c^2 (put 8 as both the leg lengths in the equation)
128 = c^2 (calculate 8^2 and then add the two terms together)
c = 8[tex]\sqrt{2}[/tex] (square both sides)
So, the length of the diagonal is 8[tex]\sqrt{2}[/tex] units
*the Pythagorean theorem is a theorem used to find the sides lengths of a right triangle: a^2 + b^2 = c^2. a and b are the legs of the triangle, and c is the hypotenuse.

Find the values of x and y in parallelogram PQRS. PT=y, TR=4x+1, QT=2y, TS=3x+12 In parallelogram PQRS, diagonals PR and QS cross at point T. Q P S R T x=nothing and y=nothing
Here is my answer. I hope this is helpful.
The required values of x and y are x = -2 and y = 7 in parallelogram PQRS.
How to find the values of x and y?To find the values of x and y, we can use the fact that the diagonals of a parallelogram bisect each other. This means that the line segment PT is equal to half of the diagonal PR, and the line segment QT is equal to half of the diagonal QS.
We can set up two equations to represent this information:
PT = 1/2 × PR
QT = 1/2 × QS
Since we are given the lengths of PT and QT, we can substitute those values into the equations:
y = 1/2 × PR
2y = 1/2 × QS
We can then use the fact that the opposite sides of a parallelogram have equal lengths to find the values of PR and QS:
PR = PT + TR = y + (4x + 1)
QS = QT + TS = 2y + (3x + 12)
Substituting these values into the equations above, we get:
y = 1/2 × (y + (4x + 1))
2y = 1/2 × (2y + (3x + 12))
Solving these equations simultaneously will give us the values of x and y.
First, we can solve the second equation for y:
y = (1/2) × (2y + (3x + 12))
y = y + (3x + 12)/2
0 = 3x + 12/2
0 = 3x + 6
-6 = 3x
x = -2
Substituting this value of x into the first equation, we can solve for y:
y = 1/2 * (y + (-2 * 4 + 1))
y = 1/2 * (y - 7)
2y = y - 7
y = 7
Therefore, the values of x and y are x = -2 and y = 7.
