The number 81.54 is 107.99% percentage of 75.5
We have,
To find what percent of 75.5 is 81.54, we can use the following formula:
(81.54 / 75.5) * 100
Step 1: Divide 81.54 by 75.5:
81.54 / 75.5 ≈ 1.0799
Step 2: Multiply the result by 100 to convert it to a percentage:
1.0799 * 100 ≈ 107.99
Therefore, 81.54 is approximately 107.99% of 75.5.
To explain it further, if we consider 75.5 as the whole or 100%, then 81.54 is approximately 107.99% of that whole value.
Thus,
In other words, 81.54 represents about 107.99% of 75.5.

Answer:
x = - 7, x = - 1
Step-by-step explanation:
Given
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = 7 and 7 + 1 = 8 , then
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1
Answer:
Step-by-step explanation:
where a 0 so a = 1 b = 8 c = 7
Quadratic Formula:
Evaluate the exponent and multiply 4ac
Subtract b^2 - 4ac and multiply 2a
Solve for the sqrt root of 35
x = - 8 ± 6/2 =
x = - 8 + 6/2 = -1
x = - 8 - 6/2 = -7
Answer:
| -2 1/5 - 4.35|
Step-by-step explanation:
Take the absolute value of the difference of the two number
| -2 1/5 - 4.35|
A.) Substitute the values into the vertical motion formula h=-16t^2+vt+c. Let h=0
B.) Use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second.
1.)0= -16t^2 + 135t + 76; 0.5 s
2.)0= -16t^2 + 135t + 76; 9 s
Answer:
The answer is 2.)
Step-by-step explanation:
Given initial velocity=135 ft/s
& cliff=76 foot
Given quadratic equation
⇒ (let h=0 it is given)
⇒
⇒
⇒ t=8.96≈9 s (the other root is negative)
Hence, rocket will take 9 s to hit the ground after launched.
A point is a location and a line has many points located on it.
A line and a point cannot lie on the same plane.
A line and a point cannot be collinear.
2. Trisha drew a pair of line segments starting from a vertex.
Which of these statements best compares the pair of line segments with the vertex?
The line segments and the vertex have length as a dimension of measurement and there are three collinear points on each.
Line segments and the vertex have two endpoints each and the distance between the end points is their dimension.
Line segments have two endpoints and a vertex is a common endpoint where two line segments meet.
The line segments and the vertex have their lines extending in one direction only and the lengths of both are infinite.
