Answer:
A = 71.3 square inches
Step-by-step explanation:
31/4 · 46/5 = 713/10 or 71.3
as decimals you can multiply 7.75 x 9.2, which is 71.3
The product of a number and 9 falls short of 78 by 6, what is the number? Show working.
Answer:
8
Step-by-step explanation:
78 - 6 = 72 (Since the number falls short by six)
72 ÷ 9 = 8 (Number times 9 that equals 72)
slope and y-intercept of the graph of 25x -20y =100
Step-by-step explanation:
First, we need to put this standard form into slope-intercept form
To do this you need to move the "y" to all by itself
-25x+25x-20y=100-25x
-20y=100-25x
y=5/4x-5
Answer:
y=5/4x-5
The slope is-5/4 and the -intercept is (0,5)
How to find the slop?
Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.
25x−20y=100
20y = 100 + 25x
20y=100+25x
y = [tex]5 + \frac{5}{4}[/tex]
She concluded that the slope is [tex]\frac{5}{4}[/tex]
and the y-intercept is (0,5).
y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.
The slope is-5/4 and the -intercept is (0,5)
Finding the value of y at x=0 will allow you to locate the y-intercept on a graph. The graph's intersection with the y-axis occurs here.To learn more about slop refer to:

y = -63 y = 8x + 6
Use Substitution to solve
9514 1404 393
Answer:
(x, y) = (-8.625, -63)
Step-by-step explanation:
Substitute for y.
-63 = 8x +6
-69 = 8x . . . . . subtract 6
-69/8 = x = -8.625
The solution is (x, y) = (-8.625, -63).

y=4x+3
2x-3y=21
SHOW YOUR WORK
Step-by-step explanation:
y = 4x+3
2x-3y = 21
2x -3(4x+3) = 21
2x -12x -9 = 21
-10x = 21 + 9
-10x = 30
x = -3

A fence is to be enclosed around a square park of side 15m. Atleast how many metres of fencing are needed?
Answer: 60 m
Step-by-step explanation:
The park is said to be square which means that all of its sides are equal.
If the fence is supposed to be put around the park, it is an indirect question asking for the perimeter of the square.
Perimeter of a square:
= 4 * length
= 4 * 15
= 60 m

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio
Answer:
6:2
Step-by-step explanation:
X share from old ratio is 1/2
Y share from old ratio is 1/3
Z share from old ratio is 1/6
Now, we are told Y retires and that X and Z purchase his shares.
Thus;
Amount X took from Y = 1/2 × 1/3 = 1/6
Amount Z took from Y = 1/6 × 1/3 = 1/18
Thus, new share of X is now; 1/6 + 1/2 = 2/3
New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9
Ratio is now X:Z = 2/3 : 2/9 = 6:2

Answer:
14. She deposited $15.50 into her bank.
15. The width would be 900.
Step-by-step explanation:
14. 245.60 + x = 261.10
x = 15.50
245.60 + 15.50 = 261.10.
She deposited $15.50 into her bank and resulted in her new bank balance appearing as $261.10.
15. Width is 900 cm
Length is 12 cm.
A = L X W = 108
A = L * 3/4L
108 = 3/4L2
Divide both sides by 3/4: multiply both sides by the inverse of 3/4 or 4/3.
(4/3)*108 = L2
144 = L2
√144 = L
12 = L
W = 3/4*12
W = 9
Before we finish:
A = 108 = 9 x 12 = 108
W/L = 3/4 = 9/12 = 3/4
The width of the rectangle would be 3/4.

Solve the equation: 12(x + 8) = 11x - 5 What is the solution?
Answer:
We conclude that the solution is:
[tex]x = -101[/tex]Step-by-step explanation:
Given the equation
[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]
Expand 12(x + 8): 12x + 96
[tex]12x+96=11x-5[/tex]
Subtract 96 from both sides
[tex]12x+96-96=11x-5-96[/tex]
Simplify
[tex]12x=11x-101[/tex]
Subtract 11x from both sides
[tex]12x-11x=11x-101-11x[/tex]
Simplify
[tex]x=-101[/tex]
Therefore, we conclude that the solution is:
[tex]x = -101[/tex]Solve each equation. Leave the answer as an improper fraction. 16x^2 = 49

a metal pipe is 77 cm long the inner diameter of the cross section is 4 cm and the outer diameter is 4.8 cm find the (i) inner curved surface area (ii) outer curved surface area (iii) total surface area
Answer with full step by step explaination
Answer:
Step-by-step explanation:
outer area=
first need to find the circumference of outer diameter
= π×4.8
= 15.079644.... cm
to find the outer curved area you would then do
= 77×15.079644
(ii) =1161.13264 cm²
inner curve area
circumference= π×4
=12.5663706.... cm
77×12.5663706
(i) =967.610537 cm²
total surface area=
as the outer and inner curved areas are already found only the top and bottom surfaces need to be
= area of larger circle
=π×4.8²
=72.382294.... cm²
smaller circle
=π×4²
=50.2654824.... cm²
72.382...-50.265
=22.1168116 x 2
=44.2336232 cm²
total surface area
(iii)= 2172.9768 cm²
(round this to however many decimals you need)
