A roll of ribbon was 8m long karmila cut 6 pieces pf ribbon each length 2/3 to tie some present then cut the remaining ribbon into some peices each of length 3/4
a) how many peices of ribbon each 3/4 m did karmila have
b) what was the length of ribbon left over
a) Karmila have 5 pieces of ribbon each 3/4 m long
b) the length of ribbon left over = 1 m
A roll of ribbon was 8m long.
Karmila cut 6 pieces of ribbon each length 2/3
Total length of 6 pieces of ribbon having length 2/3 would be,
6 * (2/3) = 4 m
This means, after cutting 6 pieces of ribbon, the length of the remaining ribbon = 4 m
Then we need to cut the remaining ribbon into some pieces each of length 3/4
Let t be the number of pieces.
So, we get an equation
(3/4) * t = 4
t = 4 * (4/3)
t = 16/3
t = 5 1/3
t ≈ 5
This means, Karmila have 5 pieces of ribbon each 3/4 m long and the length of ribbon left over = 1m
Therefore, a) Karmila have 5 pieces of ribbon each 3/4 m long
b) the length of ribbon left over = 1 m

An object is dropped from the top of a tower with a height of 1190 feet. Neglecting air resistance, the height of the object at time t seconds is given by the polynomial "-16t^2+1190." Find the height of the object at t=1 second
The height of the object at the time t = 1 second is given by 1174 feet.
Given the height of tower is 1190 feet.
The height of the object at time t seconds is given by,
h(t) = [tex]-16t^2[/tex] + 1190
So the height of the object after time t = 1 second is given by,
h(1) = [tex]-16\times 1^2+1190[/tex] = -16 + 1190 = 1174 feet
Hence the height of the object at the time t = 1 second is 1174 feet.

A ratio is a comparison of two quantities. For example, the ratio of cows to pigs on a farm could be 1 to 3. For every 1 cow, there are 3 pigs. The ratio of chocolate chips to raisins in a cookie could be 5 to 9. For every 5 chocolate chips in the cookie, there are 9 raisins. Do you notice a repeating phrase in these examples? “For every” is key ratio language. It tells you how much of one quantity exists in comparison to the other quantity. A ratio consists of just the numbers, not the units. If someone asked the ratio of chocolate chips to raisins in the cookie example, you’d say 5 to 9.

After 4 hour, the volunteer still has to knit 3 feet, which means
time taken by volunteer to knit 2 feet scarf = 4 hours
So , the time taken by volunteer to knit 1 feet scarf = 4/2 = 2 hours .
hence , the the time taken by volunteer to knit the 5 feet scarf is calculated by using the formula
= 5 × (time taken to knit 1 feet)
= 5 × (2)
= 10 hours .
Therefore , The time taken to knit the scarf form start to finish is 10 hours .

The slope of the line is 1/5 and it means the each headband uses 1/5 yards of fabrics
First choose two points
The first point = (3, 3/5)
The second point = (5, 1)
The slope of the line is the change in y coordinate with respect to the change in x coordinate of the line
The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where [tex](x_1,y_1)[/tex] is the coordinates of the first point
[tex](x_2,y_2)[/tex] is the coordinates of the second point

The volume of the largest right cylinder that fits in a sphere of radius 4 units is 143 m².
Let the diameter of the cylinder be “d" and the height of the cylinder be “h".
Given radius of the sphere = r = 4m
Diameter of the sphere = d = 2r = 2×4 = 08 m

Rama had used 0.10 as an approximation for the length of each bead, the row would have been too short and would have dropped outside of the allowed length range.
Rama is stringing beads whose lengths are each 0.19 inches.
A bead's length is 0.19 inches, which is approximately 0.2 inches. If the row has 9 beads, we must double the length of each bead by the number of beads. Therefore
Because the beads are approximately 0.20 inches in length, the length of a row of 9 beads is

A rectangular box has a square base. The combined length of a side of the square

a. Write a polynomial function in factored form modeling the volume V of the box.
b. What is the maximum possible volume of the box?
c. Explain how you found the maximum possible volume.
A) A polynomial function in factored form modeling the volume V of the box is; V(x) = x²(20 - x)
B) The maximum possible volume of the box is; 1185.19 in³
C) The way the maximum possible volume is found is by finding the derivative and equation to zero. Thereafter, we substitute the value into the first equation.
How to Maximize Volume?The formula for volume of a rectangular box is;
V =L * W * Height
Where;
L is length
W is width
H is height
We are given;
Height; h
Square base and so;
L = W = x
Thus, the volume is;
V = (x)(x)(h)
The combined length of a side of the square base and the height is 20 in. Thus; x + h = 20
h = 20 - x
Thus, volume is;
V(x) = x²(20 - x)
2) The expanded form of the volume is; V(x) = 20x² - x³
dV/dx = 40x - 3x²
The function has maxima and minima when dV/dx = 0. Thus;
40x - 3x² = 0
Solving for x gives;
x = 0 or 40/3
Maximum possible volume is;
V(40/3) = 20(40/3)² - (40/3)³
V(40/3) = 1185.19 in³
c) The way the maximum possible volume is found is by finding the derivative and equation to zero. Thereafter, we substitute the value into the first equation.

What is the height of a trapezoid with an area of 24 square inches if the two bases measure 4 inches and 6 inches?.
4.8 inches is the height of a trapezoid with an area of 24 square inches if the two bases measure 4 inches and 6 inches.
Using the formula for the area of a trapezoid, which is:
Area = (1/2)(b1 + b2)h
In this formula, b1 and b2 are the lengths of the two bases of the trapezoid, and h is the height of the trapezoid. In our problem, we know that the area is 24 square inches, and the lengths of the two bases are 4 inches and 6 inches. We want to solve for h, the height of the trapezoid.
Plugging in the known values, we get:
24 = (1/2)(4 + 6)h
24 = (1/2)(10)h
24 = 5h
4.8 = h

1) What is the equation of the line perpendicular to y = (1/2)x - 2 that
contains the point (2, 5)?
y-5= -2(x - 2)
y-5=-1/2(x - 2)
y-2=-2(x - 5)
y- 5 = 1/2(x - 2)
Answer:
(a) y -5= -2(x -2)
Step-by-step explanation:
You want the equation of the line perpendicular to y = (1/2)x - 2 that contains the point (2, 5).
Perpendicular linesPerpendicular lines have slopes that are opposite reciprocals of one another. The slope of the given line is the x-coefficient: 1/2. Its opposite reciprocal is ...
-1/(1/2) = -2
Point-slope equationThe point-slope equation of a line is ...
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
You want a line with slope -2 through point (2, 5), so its equation is ...
y -5 = -2(x -2)
