Answer:
8mStep-by-step explanation:
Step one:
given data
length of rectangle= 24.5m
let the width be x
width of square= 14m
let the length be x
Step two:
we know that the area of a rectangle is
Ar= Length * width
Ar=24.5*x-----------1
Also, the area of the square is
As= Length * width
for square L=W
As= 14*14-----------------2
As=196m^2
equating 1 and 2 we have
14*14=24.5x
196=24.5x
divide both sides by 24.5
x=196/24.5
x=8m
The Breadth/width of the rectangular park is 8m

Solve the simultaneous equations:
3a-2b=14
4a+3b=13
Answer:
Step-by-step explanation:
3a-2b=14 multiply by 3
9a - 6b = 42 (1)
4a+3b=13 multiply by 2
8a +6b = 26 (2)
sum up (1) and (2)
17a = 68
a =4
b=-1
Answer:
a = 4 b = -1
Step-by-step explanation:
13 = 4a - 3b (1)
14 = 3a + 2b (2)
(1) x 2
(2) x 3
26 = 8a - 6b (3)
42 = 9a + 6b (4)
(3) + (4)
68 = 17a
68/17 = 17a/17
a = 4
Substitute back in to original equation
14 = 3(4) - 2b
14 = 12 - 2b
14 - 12 = 12 -12 - 2b
2 = -2b
Divide by -2 both sides
b = -1
Check
3(4) - 2(-1)
12 + 2 = 14
An unused roll of paper towels is shown. What is the volume of the unused role
Answer:
1310.4
Step-by-step explanation:
26 x 12= 312 x 4.2= 1310.4
The volume of the unused role is 821.34π cm³
What is the volume?Volume is defined as the space occupied within the boundaries of any three-dimensional solid.
Given that is a figure of unused roll of paper towels, we need to find the volume of the unused role,
The volume of a cylinder with radius r and height h is V = π·radius²·height
To find the same we will subtract the volume of the inner cylinder from the outer,
Volume = 6²π(26) - (2.1)²π(26)
= 26(36π - 4.41π)
= 26(31.59π)
= 821.34π cm³
Hence, the volume of the unused role is 821.34π cm³

Writing proportional equations Problem The Green Goober, a wildly unpopular superhero, mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume. Write an equation that relates yyy, the amount of yellow paint in liters, and bbb, the amount of blue paint in liters, needed to make the Green Goober's special green paint.
Answer:
The equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters [tex]5y-3b=0[/tex].
Step-by-step explanation:
Given that The Green Goober mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume.
So,
The amount of yellow paint: the amount of blue paint [tex]= 333: 555[/tex]
If the amount of yellow paint is y and the amount of blue paint is b, then, from the above relation
[tex]y: b = 333: 555\Rightarrow \frac y b = \frac {333}{555} \\\\\Rightarrow \frac y b = \frac {3}{5} \\\\\Rightarrow 5y=3b \\\\\Rightarrow 5y-3b=0.[/tex]
Hence, the equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters [tex]5y-3b=0[/tex].
Answer:
5y-3b=0

Solve 2x + 6 > 20.

O B. x>7
O c. x< 13
O D. x<7
Answer:
the answer is x>7
Step-by-step explanation:
The solution of the inequality 2x + 6 > 20 is x<7.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
We have the inequality 2x + 6 > 20.
Now, Subtract 6 from both side we get
2x+ 6 - 6< 20 - 6
2x < 14
Divide both side by 2 we get
2x/2 < 14/2
x< 7

18
Step-by-step explanation:
If a polynomial f(x) is divided by (x + h) then the remainder is equal to f(- h)
Given
f(x) = x³ + 4x² - 7x - 10 and divided by (x + 4), then the remainder is
f(- 4) = (- 4)³ +4(- 4)² - 7(- 4) - 10 = - 64 + 64 + 28 - 10 = 18

Answer:
D: 2/3x - 13/12 = -5/12x
Step-by-step explanation:
2/3x - 5/6 = -5/12x + 1/4
To simplify, the denominator must be the same. So,
5/6 = 10/12
and 1/4 = 3/12
Then, you move the values to the same side via addition or subtraction.
2/3x (- 10/12 - 3/12) = -5/12x
2/3x - 13/12 = -5/12x

Will give brainliest! TYSM! <3

Answer:
B. The graph flips over the x-axis
Step-by-step explanation:
When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.
The graph flips over the x-axis.

There are 2300 ways by which we can select 3 students out of 25 students.
What is Combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.
Here total number of Students = 25
Number of selection = 3
Now,
Total number of ways by which we can select 3 out of 25 = ²⁵C₃
= 25!/3!.22!
= 25 X 24 X 23 X 22! / 3X2X1 X 22!
= 13800 / 6

1. What will happen to the current if the voltage is decreased by one half while the
resistance is held constant? State the relationship of voltage and current based
on your answer.
Answer: Current will reduce by half
Step-by-step explanation:
The formula for Current is;
Current = Voltage/ Resistance
Say for instance that Voltage is 5 volts and Resistance is 2 ohms. Current will be;
= 5/2
= 2.5 amps
If Voltage is decreased by one half to 2.5 while resistance is held constant, current becomes;
= 2.5/2
= 1.25 amps
Current went from 2.5 to 1.25 amps.
This shows that current will reduce by half if the voltage is decreased by one half while the resistance is held constant.
