Find the area of the shaded region.
Answer:
SOLUTION,
HERE,
Area of whole fig= l×b
=5×15
=75 sq.in
Area of unshaaded part=l×b
=3×8
=24 sq.in
Area of shaded part=(Area of whole fig)-(Area of unshaded part)
=75-24
=51 sq.in

Substitute this simultaneous linear equation
[tex]2x + 2y = 14 \\ 5x - 2y = 14[/tex]
Answer:
[tex]2x + 2y = 14 \: .....(1) \\ \\ 5x - 2y = 14 \: .....(2) [/tex]
From equation (1) ;
[tex]2x + 2y = 14 \\ \\ 2y = 14 - 2x \\ \\ y = \frac{14 - 2x}{2} \\ \\ y = 7 - x[/tex]
Substitute in equation (2)
[tex]5x - 2y = 14 \\ \\ 5x - 2(7 - x) = 14 \\ \\ 5x - 14 + 2x = 14 \\ \\ 7x = 14 + 14 \\ 7x = 28 \\ \\ x = \frac{28}{7} \\ \\ x = 4[/tex]
[tex]y = 7 - x \\ y = 7 - 4 \\ \\ y = 3[/tex]

MODELING WITH MATHEMATICS The Uniform
Federal Accessibility Standards specify that a
wheelchair ramp may not have an incline greater
than 4.76°. You want to build a ramp with a vertical
rise of 8 inches. You want to minimize the horizontal
distance taken up by the ramp. Draw a diagram
showing the approximate dimensions of your ramp.
The length of the ramp is 96.5
SOH CAH TOA identityGiven the following parameters from the question
The vertical rise of the ramp = 8 inches
The angle of elevation = 4.76°.
Required
length of the ramp
Using the SOH CAH TOA identity;
tan theta = opp/hyp
sin4.76 = 8/H
H = 8/sin4.76
H = 8/0.0829
H = 96.5
Hence the length of the ramp is 96.5

If the circumference of a circle is 43.4 cm,
then what is the diameter? Use 3.1 for n.
Answer:
the diameter is 14cm
Step-by-step explanation:
to get the circumference of a circle you would need to times the diameter (d) by pi or in this case n which is 3.1
this result is 43.4cm
now to figure out the diameter we would have to reverse this so the equation would be
d=43.4/n
which is the same as d= 43.4/3.1
the result of this is d= 14
so the diameter is 14cm.

Mandy and Joshua work together on Market Day at their school. They split the profit according to the ratio 2 : 3 respectively. They make a profit of R825.Calculate the amount Mandy will receive.
Answer:
R330
Step-by-step explanation:
2 + 3 = 5
5x = 825
2x = 825 x 2/5
825 x 2 = 1650
1650/5 = 330
Mandy makes R330.
Mandy's share from the profit is R495
Data;
Profit = R825ratio = 2:3RatiosThis is the portion shared between two or more entities in a definite proportion.
To find Mandy's share, let's add 2 and 3 and then take the fraction of 3/5 and multiply it by the profit made.

T minutes ,N people with the formula = t= 5n^2 +15
a)When there is four people what's the minutes
b) when the time is 2hours 20mins how many people
Answer:
a) n = 4 , t = ?
[tex]t = 5 {n}^{2} + 15 \\ \\ t = 5 {(4)}^{2} + 15 \\ \\ t = 5(16) + 15 \\ \\ t = 80 + 15 \\ \\ t = 95 \: min[/tex]
__o__o__
b) n = ? ,
t = 2hours 20mins ––> t = (2× 60) mins + 20 mins
t = 120 + 20 = 140 mins
so; time in the mins = 140 mins
[tex]t = 5 {n}^{2} + 15 \\ \\ 140 = 5 {n}^{2} + 15 \\ \\ 5 {n}^{2} = 140 - 15 \\ \\ 5 {n}^{2} = 125 \\ \\ {n}^{2} = \frac{125}{5} \\ \\ {n}^{2} = 25 \\ \\ n = 5[/tex]
so ; five people in 2hours 20mins

Enter your answer as a mixed number in simplest form in the box.
x =
Answer:
x= 21/4
Step-by-step explanation:
1- Convert the expressions
5 ( x - 3 3/4 ) = 7 1/2
2- Remove the parentheses
5 ( x - 15/4 ) = 15/2
3- Move the constant to the right
5x - 75/4 = 15/2
4- Calculate the sum
5x = 15/2 + 75/4
5- Divide both sides
5x = 15/2 + 75/4

Answer:
-3
Step-by-step explanation:
Lets convert 4 2/3 to an improper fraction
-(4 * 3/3 + 2/3)/1 5/9
Combine 4 and 3/3
-(4 * 3/3 + 2/3)/1 5/9
Combine numerator over denom
-4 * 3 + 2/3/1 5/9
Simplify numerator
-12 + 2/3/1 5/9
Add 12 and 2
-14/3/1 5/9
Now we convert 1 5/9 to an improper.
-14/3/(9/9) + (5/9)
Combine
-14/3/(9 + 5)/9
Add 9 and 5
-14/3/(14/9)
Multiply yhe numerator by the reciprocal of the denom
-14/3 * 9/14
14(-1)/3 * 9/14
-1/3 * 9
Cancel the common factor of 3
-1/3 * (3(3))
-1 * 3 = -3
S.p=208rs, profit percentage=4%. Find c.p
Given :
Selling price is Rs 208 .Profit percentage is 4% .To Find :
The cost price .Solution :
Let us suppose ,
→ CP = Rs x
Therefore the profit will be ,
→ Profit = SP - CP
→ Profit = 208 - x
Now we know that ,
→ Profit% = profit/CP * 100
Substituting the respective values ,
→ 4 = (208-x)/x * 100
→ 4 * x = (208- x)*100
→ 4x = 20800 - 100x
→ 100x + 4x = 20800
→ 104x = 20800
→ x = 20800/104
→ x = 200
Hence the cost price is Rs 200.

What is the factorization of the polynomial below ? 16x2 -9
Answer:
(4x + 3)(4x - 3)
Step-by-step explanation:
I am going to assume by 16x2 -9 you mean 16x² - 9
The factorization means the factors are "broken" up. If you multiply them together, we will reach 16x² - 9 again.
First, we can look at factors of 9. This gives us 1, 3, and 9. We will use 3. Since the nine is negative, one will be + 3 and one will be - 3 since a negative times a positive is a negative.
( + 3)( - 3)
Last we can factor the 16x² portion. I know that 4 times 4 is 16, and 4x times 4x is 16x².
(4x + 3)(4x - 3)

chanda wants to put 150 square metres of garden at her backyard. This is the maximum area of garden she can have. She wants to have a rectangular area of garden with length one metre less than 3 times with the width. Find the length and width to the nearest tenth of a metre
Answer:
length: 20.7 mwidth: 7.2 mStep-by-step explanation:
Let x represent the width of the garden. Then its length is 3x-1 and its area is ...
A = LW . . . . . . . . . . . . area of a rectangle is length times width
A = (3x -1)(x) = 150
3x^2 -x = 150
x^2 -1/3x +1/36 = 50 +1/36 . . . . divide by 3 and complete the square
x -1/6 = √(50+1/36) . . . . . . . . . take the square root
x = (1 +√1801)/6 ≈ 7.2397 . . . width of Chanda's garden
The length will be ...
3x -1 = 3(1 +√1801)/6 -1 = (1 +√1801)/2 -1 = (-1 +√1801)/2 ≈ 20.7191
To the nearest tenth meter, the garden is 20.7 m long and 7.2 m wide.

A sociologist sat married couples down in her office and asked some survey questions for her statistical study on marriage. The first married couple was Bonnie and Clyde. Bonnie sat down next to her husband while the sociologist sat across the table from them both. The sociologist asked each the question, if you could return to the past, would you marry your spouse all over again?" This was continued for several other married couples. This is not a good way to conduct this survey and most likely will not give representative results of all married couples. Why not?
