The length is
cm.
Given :-
The area of a rectangle is 357 cm².It's breadth is 17cm .To Find :-
The length of the rectangle.Solution :-
Here the area of the rectangle is 357cm² . As we know that the area of rectangle is ,
→ Area = length * breadth
On substituting the respective values ,
→ 357 cm² = 17cm * length
→ length = 357cm²/17cm
→ length = 21cm
Hence the length of the rectangle is 21cm.

A rock is thrown upward with an initial velocity of 16ft/sec from an initial height 5ft. How much time does it take for the rock to hit the ground?
A. -0.25sec
B. 0.5sec
C. 1.25sec
D. 1.5sec
Answer: C
The amount of time it would take for the rock to hit the ground is 1.25 seconds.
Given the following data:
Initial velocity = 16 ft/secHeight = 5 ft.Scientific data:
Acceleration due to gravity (g) = 9.8 [tex]m/s^2[/tex]To determine the amount of time it would take for the rock to hit the ground, we would apply the parabolic function:
How to calculate the time.Mathematically, the parabolic function is given by this formula:
[tex]h(t) = -16t^2 +ut+h_0[/tex]
Where:
U is the initial velocity.a is the acceleration.[tex]h_0[/tex] is the height.t is the time.Substituting the given parameters into the formula, we have;
[tex]0 = -16t^2 +16t+5\\\\16t^2-16t-5=0\\\\(4t+1)(4t-5)=0[/tex]
Taking the positive value of t, we have:
[tex]4t-5-0\\\\4t=5\\\\t=\frac{5}{4}[/tex]
t = 1.25 seconds.

Answer:
first make them improper fractions
2 2/5 = 12/5
2 1/10 = 21/10
now set them up
12/5 divided by 21/10
make 21/10 a reciprocal(flip the fraction upside down) and multiply across
12/5 x 10/21 = 1.14 or 1 1/7
Hunter and Christopher were analyzing the graph shown . Both students identified the function to be represented by the, d=13h-75, where d is the amount of money in a checking account and h is the number of hours worked. Hunter explained the equation represented an original amount of $75 that decreased $13 for every hour. Christopher disagreed. He interpreted the equation as a person who was in debt $75 earned $13 every hour.
Using linear function concepts, it is found that Christopher is correct.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can be interpreted as the initial value.In this problem, the function is:
[tex]d = 13h - 75[/tex]
Considering the description of the output d as the amount of money in a checking account and of the input h as the number of hours worked, we have that:
For each hour worked, the person earns $13.Considering taxes, the person starts at a debt of $75.Hence, Christopher is correct.

what does a(b-c) = to?
Solution:
The expression "a(b-c)" is an example of distributive property. To simplify it, simply multiply a by the terms inside the bracket.
Simplifying the distributive property.
=> a(b - c)=> (a x b) + (a x -c)=> ab - acHence, the simplified expression is ab - ac.
We can use the distributive law to simplify it or factor it but more

y=6x
54=6x
Divide both sides by 6
x=9
Answer:
x = 9
Step-by-step explanation:
Since y = 54
54 = 6x
Divide both sides of the equation by the same term

B + C - A = x² + 8x - 3 + (- 5x² - 3x + 2) - (3x² - 7x + 8) = x² + 8x - 3 - 5x² - 3x + 2 - 3x² + 7x - 8 =(1 - 5 - 3)x² + (8 - 3 + 7)x + (-3 + 2 - 8) = - 7x² + 12x - 9A = [tex]3x² - 7x + 8[/tex]

What is the length of the altitude drawn to the hypotenuse? The figure is not drawn to scale. * 12 3 X W3 x 12 Z Y Your answer
Answer:
What is the length of the altitude drawn to the hypotenuse?, Corollary: The length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.
Furthermore, When an altitude is drawn to the hypotenuse of a given right triangle the new figure comprises two similar right triangles?, Theorem 62: The altitude drawn to the hypotenuse of a right triangle creates two similar right triangles, each similar to the original right triangle and similar to each other. Figure 2 shows the three right triangles created in Figure . They have been drawn in such a way that corresponding parts are easily recognized.
Finally, When the altitude is drawn to the hypotenuse of a right triangle three similar triangles are formed?, The Inscribed Similar Triangles Theorem states that if an altitude is drawn from the right angle of any right triangle, then the two triangles formed are similar to the original triangle and all three triangles are similar to each other. Perpendicular lines are lines that intersect at a 90^{circ} angle.

A restaurant owner washed 87 kilograms of vegetables, some spinach and some carrots. The spinach came in 5-kilogram bags and the carrots came in 7-kilogram bags. The owner washed 15 bags of vegetables in all. How many bags of each kind did he wash?
Answer:
9 bags pf spinach, 6 bags of carrots
Step-by-step explanation:
x bags of spinach, y bags of carrots,
x + y = 15 (1)
weight of spinach = 5 * x, weight of carrots = 7 * x
5x + 7y = 87 (2)
From (1) y = 15 - x
Sub it into (2):
5x + 7(15 - x) = 87
5x + 105 - 7x = 87
2x = 105 - 87 = 18
x = 9
y = 15 - x = 15 - 9 = 6
So 9 bags pf spinach, 6 bags of carrots.

[tex]\red{ m\angle B= 121\degree}\\\\\purple{AD=23\: units}[/tex]
Step-by-step explanation:
Quadrilateral ABCD is a parallelogram.
opposite angles of a parallelogram are equal in measure.
[tex]\implies (10x-19)\degree=(9x-5)\degree[/tex]
[tex]\implies 10x-19=9x-5[/tex]
[tex]\implies 10x-9x=19-5[/tex]
[tex]\implies x=14[/tex]
[tex]m\angle B= (9x-5)\degree[/tex]
[tex]\implies m\angle B= (9*14-5)\degree[/tex]
[tex]\implies m\angle B= (126-5)\degree[/tex]
[tex]\huge\implies m\angle B= 121\degree[/tex]
Opposite sides of a parallelogram are equal.
3y - 1 = y + 15
3y - y = 15 + 1
2y = 16
y = 16/2
y = 8
AD = 3y - 1 = 3*8 - 1 = 24 - 1
AD = 23
