thus that means 0 + 1 = 1
Answer:
(x+3)²=(√x+3)²
x²+6x+9=x+3
x²+5x+6=0
3×2=6
3+2=5

Please help! Find the area of the shaded region.
Answers
Answer:
≈ 7.73
Step-by-step explanation:
Area of a circle = π [tex]r^{2}[/tex]
Area of a rectangle = width x height
Circle:
π [tex]3^{2}[/tex] = π 9 ≈ 28.27 area of each circle
1/2 28.27 + 1/2 28.27 = 28.27 = area of the white region
Square:
6 x 6 = 36 = area of the square (green and white combined)
36 - 28.27 ≈ 7.73 (the whole square, minus the white area)

I need help please, thank you.
I need explanation
Answers
Answer:
∠V = 102°
Step-by-step explanation:
So angle T and angle W are supplementary angles which means they sum up to 180°. With that said we can say that:
∠T + ∠W = 180
=> 78 + ∠W = 180
=> ∠W = 180 - 78
=> ∠W = 102
We know that in a parallelograms the base angles are congruent so we can say that: ∠W ≅ ∠V,
Therefore if ∠W = 102, then
∠V would also be 102°

A 70 cm long stick is cut into two parts in such a way that the longer part is 20 cm longer than the shorter part. How long is each part?
Answers
Answer:
Long part= 45
Short part= 25
Step-by-step explanation:
Let the short part of the stick be x
Let the long part be x+20
The total length of the stick is 70cm
x + (x+20)= 70
x+x+20= 70
2x+20= 70
2x= 70-20
2x= 50
x= 50/2
= 25
Longer part length= 20+25
= 45
The short part is 25
what is the surface area 1ft 1ft 1ft?
Answers
Answer:
6 ft^2
Step-by-step explanation:
If the object in question is a cube, then we could say the length is 1, the depth is 1 and the height is 1, in which case each side of the cube has an area of 1 ft^2.
There are 6 such sides, so the total surface area is 6 ft^2.
Next time please be explicit in naming the shape, either verbally or with a diagram.

the coffee does she need is [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
Given that
Mx Duncan used three fourth of the cup of coffee
And, she realized that she only required half of the three-fourth of coffee
We need to find out the how much of the coffee does she need
So,
[tex]= \frac{3}{4} \times \frac{1}{2} \\\\= \frac{3}{8}[/tex]
Hence, the coffee does she need is [tex]\frac{3}{8}[/tex]

Craig earns the same amount of money each month. His telephone bill is 1/20 of his monthly earnings, and he pays a total of $720 each year for his telephone service. How much does Craig earn each month, in dollars?
Question 3 options:
$1,200
$1,600
$60
$120
Answers
Answer:
Hello! answer: 1,200
Step-by-step explanation:
We know he pays 720 in a year so i divide that by 12 so... 720 ÷ 12 = 60 so he pays 60 each month for his telephone service since thats only 1/20 of his earning what I do is 60 × 20 and we get 1200 so craig makes 1200 a month hope that helps!
$1200, Craig earns each month.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Let's assume Craig earns $x per month.
The telephone bill is 1/20 of his monthly earnings, which is (1/20)x.
He pays a total of $720 each year for his telephone service.
Since there are 12 months in a year,
he pays (1/12) * 720 = $60 per month for his telephone service.
Therefore,
(1/20)x + $60 = x,
as he earns the same amount each month.
Simplifying the equation,
we get x/20 = $60
Multiplying both sides by 20,
we get x = $1,200
Therefore, Craig earns $1,200 per month.

Regular quadrilateral pyramid with base edge b=55mm and lateral edge l=7 cm. Find the sum of all edges
Answers
Answer:
50cm or 500 mm
Step-by-step explanation:
A quadrilateral is a four sided figure. So, the base of the quadrilateral pyramid has four sides. It also has 4 edges and 4 bases
sum of edges = sum of base edges + sum of lateral edges
1cm = 10mm
55mm = 5.5cm
sum of base edges : 5.5 x 4 = 22cm
sum of lateral edges : 7 x 4 = 28 cm
22 + 28 = 50 cm or 500mm

Answer:
x = 129
Step-by-step explanation:
Mathematically, the sum of interior angles of a polygon can be calculated using the formula;
(n-2)180
from the question given , n = 7 since the polygon has 7 sides
thus, we have it that
(7-2)180 = 5 * 180 = 900
Mathematically, by adding all the given interior angles, we can get the value of the total
We have this as;
900 = x + 131 + 119 + 125 + 133 + 125+ 138
900 = x + 771
x = 900-771
x = 129
Two points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6cn long, find the scale used to draw the plan.
Answers
Answer:
The scale is 1:200
Step-by-step explanation:
On the plan we have the drawing as 6 cm
In real representation, we have the distance as 12 m
Firstly we have to convert to same unit
In this case, we use the cm for convenience
Mathematically, 100 cm is 1 m
Thus, 12 m
will be 12 * 100 = 1,200 cm
So, we have the ratio as;
6 cm : 1,200 cm
and that is 1:200 (since 6/1200 = 1/200 and in ratio form, we have that as 1:200)

A team of construction workers worked together to build 3 sheds in 10 days. How much of a shed did they construct?
Answers
Answer:
3/7
Step-by-step explanation:
A team of 7 construction workers worked together to build 3 sheds in 10 days. How much of a shed did each of them build?
Number of workers = 7
Number of sheds = 3
7 workers built 3 sheds
let
x = number of shed each worker built
Number of sheds = Number of workers × number of shed each worker built
3 = 7 * x
3 = 7x
Divide both sides by 7
3 / 7 = 7x / 7
3/7 = x
x = 3/7
x = number of shed each worker built = 3/7
