Find the area if the composite shape
Answer:
111 m²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angle) with two pairs of parallel sides. Opposite sides of a rectangle are equal to each other. Also all the angles of a rectangle are 90° each.
The area of a rectangle = length * width
For rectangle 1, length = 12 m, width = 3 m
Therefore area of rectangle 1 = length * width = 12 m * 3 m = 36 m²
For rectangle 2, length =(12 m - 3 m - 3 m) = 6 m, width =(15 m - 10 m) =5 m
Therefore area of rectangle 2 = length * width = 6 m * 5 m = 30 m²
For rectangle 3, length = 15 m, width = 3 m
Therefore area of rectangle 3 = length * width = 15 m * 3 m = 45 m²
Area of composite shape = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Area of composite shape = 36 m² + 30 m² + 45 m² = 111 m²
Solve for w.
6w+18-9w = -12
Simplify your answer as much as possible.
W=
Answer:
w = 10
Step-by-step explanation:
6w+18-9w = -12
Combine like terms
-3w + 18 = -12
Subtract 18 from each side
-3w +18- 18 = -12 -18
-3w = -30
Divide each side by -3
-3w/-3 = -30/3
w = 10
Answer:
w = 10
Step-by-step explanation:
6 w + 18 - 9 w = - 12
combine like terms
6 w - 9 w + 18 = - 12
- 3 w + 18 = - 12
subtract each side by 18
- 3 w + 18 - 18 = - 12 -18
- 3 w = - 30
Divide each side by - 3
- 3 w / - 3 = - 30 / - 3
w = 10

Answer:
below
Step-by-step explanation:
you can find the distance between the y values for each x value and if it comes out to be an even increase/decrease you know it is linear
Answer:
It does not form a linear equation.
Step-by-step explanation:
For this question, you should check that they all have the same gradient.
To work out the gradient, use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].
Using the top 2 rows, this gives [tex]\frac{-1--3}{-2--6}[/tex], or [tex]\frac{2}{4}[/tex], simplified to [tex]\frac{1}{2}[/tex]. This means for every increase in x by 1, y increases by [tex]\frac{1}{2}[/tex].
Between the first 2 rows, x increases by 4 and y by 2 (half of 4), so it is true.
Between the second and third rows, x increases by 2 and y by 2 (which isn't half of 2). This is false, meaning this does not form a linear equation.
**This question involves solving linear equations using gradients, which you may want to revise. I'm always happy to help!

Step-by-step explanation:
8 friends go out for dinner and the bill for food and drink comes to £120. The friends decide to add a 20% tip on top of this total. If they divide the expense equally between them, how much does each friend pay?
Answer:
$18
Step-by-step explanation:
Given the following data;
Number of friends = 8
Total expense = $120
Tip = 20%
To find how much each friend would pay?
First of all, we would determine the amount of tip.
Tip = 20/100 * 120
Tip = 2400/100
Tip = $24
New balance = total expense + tip
New balance = 120 + 24
New balance = $144
Next, we find how much each friend would pay using the mathematical expression;
Each paid = 144/8
Each paid = $18
f (x) = (3x - 2). find f^-1f (10)
f-¹f(10)=10
Answer:
Solution given:
f(x)=3x-2
let
y=3x-2
interchanging role of x and y
x=3y-2
y=[tex]\frac{x+2}{3}[/tex]
so
f-¹(x)=[tex]\frac{x+2}{3}[/tex]
now
f(10)=3*10-2=28
now
f-¹f(10)=f-¹(28)=[tex]\frac{28+2}{3}[/tex]=10
Find the measure of the exterior angle.
The measure of the exterior angle of the triangle is
Answer:
X = 132
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle therefore
x = 46 + 86
x = 132
Answer:
The measures of exterior angle is 132° .
Step-by-step explanation:
We know that the sum of interior angle is equal to the sum of exterior angle of triangle.
interior angle = exterior angle86° + 46 ° = x
combine like terms
132° = x

Please help!!! Thanks!
Answer:
x=16
Step-by-step explanation:
angle TVQ = angle VWS (if they are parallel they can be said as corresponding angles)
5x-22 = 3x+10
5x-3x = 10+22
2x = 32
x = 32/2
x = 16
Answer:
B
Step-by-step explanation:
If PQ and RS are to be parallel, then
∠ TVQ = ∠ VWS ( corresponding angles ) , that is
5x - 22 = 3x + 10 ( subtract 3x from both sides )
2x - 22 = 10 ( add 22 to both sides )
2x = 32 ( divide both sides by 2 )
x = 16
For PQ and RS to be parallel then x = 16
What is the equation of a circle with center (2, -5) and
radius 4?
Answer:
(x-2)^2 +(y+5)^2=4^2
Step-by-step explanation:
x minus 2 squared + y plus 5 squared = radius squared
Answer:
(x-2) ^2 + ( y+5)^2 = 16
Step-by-step explanation:
The equation for a circle is given by
(x-h) ^2 + ( y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-2) ^2 + ( y- -5)^2 = 4^2
(x-2) ^2 + ( y+5)^2 = 16
Finding angles June 23,2022
Answer:
61 degrees
Step-by-step explanation:
Considering angle <GJI and <IKD, these two angles are corresponding angles. Recall that corresponding angles are equal hence,
m<GJI = m<IKD = 119 degrees
Again
m<GJI and m<AJG are on a straight line at a point. Recall that the sum of angles on a straight line is 180 degrees. Hence
m<GJI + m<AJG = 180
119 + m<AJG = 180
m<AJG = 180 - 119
= 61 degrees

x + 2/3 = 8/9 x=__ ..........................................
Answer:
x = -6
Step-by-step explanation:
[tex]x+\frac{2}{3}=\frac{8}{9}x\\\\x = \frac{8}{9}x - \frac{2}{3}\\\\x - \frac{8}{9}x= -\frac{2}{3}\\\\\frac{9}{9}x-\frac{8}{9}x=\frac{2}{3}\\\\\frac{1}{9}x=-\frac{2}{3}\\\\x=-\frac{2}{3}*\frac{9}{1}\\\\x=(-2)*3\\\\x = -6[/tex]
Answer:
x = [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
Given
x + [tex]\frac{2}{3}[/tex] = [tex]\frac{8}{9}[/tex] ( multiply through by 9 to clear the fractions )
9x + 6 = 8 ( subtract 6 from both sides )
9x = 2 ( divide both sides by 9 )
x = [tex]\frac{2}{9}[/tex]

I thought of a number, multiplied it by 2 ½ , divided the result by 1 1/5 , subtracted 7/18 from it, and got 1 ⅚ . What was my number?
Answer:
1.06 or 1 1/15
Step-by-step explanation:
So, basically what we need to do is reverse the steps.
So now it goes like this:
We start with 1 5/6(1.83)
Then we add 7/18(0.389)
Then we multiply by 1 1/5(1.2)
Then finally, we divide by 2 1/2(2.5)
This will get us our answer. So:
1.83+0.389 = 2.219
2.219*1.2 = 2.6628
2.6628/2.5 = 1.06
This is 1.06 in decimal form, or 1 1/15 in fraction form
Hope this helps!
This can also be double checked, if you plug it into the orginal equation:
1.06, then you multiply by 2.5: 1.06*2.5= 2.6628
2.6628, then you divide by 1.2: 2.6628/1.2= 2.219
Then finally, 2.219 and subtract 7/18: 2.219-0.389= 1.83
So we have double checked, and our answer is still 1.06.

What is the value of x?
45°
m
(2x-5)
n
Answer:
x = 70
Step-by-step explanation:
The two angles are same side interior angles and same side interior angles add to 180
45+ (2x-5) = 180
Combine like terms
2x +40 = 180
Subtract 40 from each side
2x+40-40 =180-40
2x =140
Divide by 2
2x/2 = 140/2
x = 70
Answer:
x=70

What is the radius of a sphere with a volume of 996 cm 3 , 996 cm 3 , to the nearest tenth of a centimeter?
Answer: [tex]6.2\ cm[/tex]
Step-by-step explanation:
Given
The volume of the sphere is [tex]V=996\ cm^3[/tex]
Volume of sphere is given by [tex]V=\dfrac{4}{3}\pi r^3[/tex]
Insert the values
[tex]\Rightarrow 996=\dfrac{4}{3}\times \dfrac{22}{7}r^3\\\\\Rightarrow r^3=\dfrac{996\times 21}{88}\\\\\Rightarrow r=6.2\ cm[/tex]
Thus, the radius of the sphere is [tex]6.2\ cm[/tex]

Help pls pls pls pls
Answer:
C
Step-by-step explanation:
Answer:
option c is correct
Step-by-step explanation:
y = 2x +5
5 = 2*0 +5
5 = 0 +5
5=5
y = 2x +5
9 = 2*2 + 5
=9 = 4 +5
9=9
y = 2x +5
13 = 2*4 +5
13 = 8 + 5
13 = 13
therefore option c is correct because it satisfies all the elements of x and y of the given function when we substitute the values.

Answer: B) 0.50x+15=25
Step-by-step explanation:
So we know she earns 15 dollars each week and she wants to get 25 dollars.
So far our equation is ?+15=25
For every customer on her paper route she gets $0.50. For 1 customer she'd get $0.50. For 2 she'd get $1. As you can see the customers she gets is multiplied by 0.50 to see how much money she makes. So, for x customers she'd get 0.50x dollars.
So now we can add that to our equation
0.50x+15=25

If f(x) = 3x2 + 1 and g(x) = 1 – x, what is the value of (f – g)(2)?
12
14
36
38
Answer:
14
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² + 1 - (1 - x)
= 3x² + 1 - 1 + x
= 3x² + x
Then
(f- g)(- 2)
= 3(- 2)² + 2
= 3(4) + 2
= 12 + 2
= 14
The cost of a computer processor is directly proportional to its speed.
A 4GHz processor costs £400.
Find the cost of a 6GHz processor
Answer:
Step-by-step explanation:
If cost is directly proportional to speed, then the equation for this is
£ = ks, where k is the constant of proportionality. We need to solve for this first.
400 = k4 so
100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:
£ = (100)(6) so
£ = 600
