One side of a square became twice as big and the other twice as small, the newly created rectangles area is 28cm2 smaller then the square it used to be.
What is the perimeter of the rectangle?
Answer: Simple way: If the perimeter is 22, the sum of length and breadth is 11 Cm. Now the Area is 28. Factorizing 28, Possible combinations are (1,28),(2,14),(4,7).

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Step-by-step explanation:
a = \(\sqrt{12^2 -9^2} = \sqrt{144-81} = \sqrt{63}\)
We use the minus because we are searching a leg.
A leg is always shorter than the hypotenuse
Answer:
a = 7.9 or a = √63
Step-by-step explanation:
a² + b² = c²
(The two shorter sides of a triangle are always a and b while the longer side will always be c)
So, here the longer side of this triangle is 12 and the shorter sides are 9 and a (unknown).
The equation is: a² + 9² = 12²
But to find the value of a, the formula will be 12² - 9² = a²
12² - 9² = a²
144 - 81 = a²
63 = a²
the square root of 63 = 7.9 so that means a = 7.9

Answer:
Strawberry= 3
Watermelon=3
Coconut=9
Orange=5
Step-by-step explanation:
Quite easy, you can use substitution
First look at the simplest row that can be solved by itself
row 2:
2strawberries +4 = 10
2 strawberries= 6
1 strawberry = 3
Row 3: Strawberry(3)+ orange=8
1 orange= 5
Rpw 4: 14= 1coconut +orange(5)
1 coconut= 9
Row 1: Coconut(9)+ watermelon+ coconut(9)= 21
2 coconut(18)= 21
1 watermelon = 3
Ok so, A mother has 5 children, the first child is 27 (late twenties), the Second is 22 (early twenties), the middle child is 21 years old, the fourth is 12, and the youngest is 11. The first has a child that is 1 year younger then the youngest child. How is that possible? Explain how you got your answer. (Not really a question from school, so answer whenever you want, I'll give the brainiest to who can also guess the years they were born in and what age the first child was at the moment she had the child ig)
Answer:
The first child has a child who is 10 years old. Since the first child is is 27, that means she gave birth when she about 17 years old, depending on when their birthday's are.
Step-by-step explanation:
This doesn't seem impossible, so I'm wondering if I'm missing something? You also didn't mention if they were male or female, but again, it's not impossible to give birth or father a child at age 17.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

Step-by-step explanation:
Let’s mark the Triangle Points as Point A, Point B, Point C.
Point A = 1x°
Point B = 2x°
Point C = 3x°
We know that the Angle Sum of a Triangle is equal to 180°.
So, Point A + Point B +Point C = 180°
= 1x° + 2x° + 3x° = 180°
= (1 + 2 + 3)x° = 180°
= 6x° = 180°
= x° = (180/6)°
= x° = 30°

First Picture: 2032*93 = 188976, 425/25 = 17
Second Picture: the machine is dividing the number by 6
Third picture: 85
Step-by-step explanation:
Second Picture: 36/6 = 6 and 54/9 = 6 therefore the machine is dividing by six
Third Picture: a multiple of 7 is 84 (7*12 = 84). 85 is one more than a multiple of 7. Therefore 85 is the answer. A formula can be 7x + 1 = (then try out different numbers in the grid)
7x+1 = 85
7x = 84
x = 84/7
x = 12

I need in form of y=mx+b Thank you!
Answer:
y = -2x + 3
Step-by-step explanation:
Let equation of the line be y = mx + b
Since the line is perpendicular to y = 1/2x - 10,
product of the gradient of both lines = -1
therefore,
1/2 x m = -1
m = -2
since it passes through (4, -5),
sub (4, -5):
-5 = -2(4) + b
b = 3
therefore, equation of the line is y = -2x + 3

Tyrell is traveling to Chicago, Illinois. He takes a cab service from the airport to his hotel. The table shows the linear relationship between the number of miles the cab travels, x, and the total fee, y.
Cab Fare
Number of Miles Total Fee
2 $13.00
5 $17.50
7 $21.50
10 $25.00
15 $32.50
What does the y-intercept mean in this situation?
For every additional mile the cab travels, the total fee increases by $10.00.
For every additional mile the cab travels, the total fee increases by $1.50.
When the cab travels 0 miles, the total fee will be $1.50.
When the cab travels 0 miles, the total fee will be $10.00.
The meaning of the y-intercept in this situation is that: D. when the cab travels 0 miles, the total fee will be $10.00.
How to calculate the slope of a line?
Mathematically, the slope of a straight line can be calculated by using this formula;
From the table, we have the following parameters:
Points (x, y) = (2, 5) and (13.00, 17.50)
Next, we would calculate the slope as follows:
Slope = (17.50 - 5)/(13.00 - 2)
Slope = 12.50/11.
Slope = 1.14.
Mathematically, the standard form of the equation of a straight line is given by;
y - y₁ = m(x - x₁)
Where:
x and y represents the points.
m represents the slope.
b represents the y-intercept.
Substituting the given parameters into the standard equation, we have;
y - 13.00 = 1.14(x - 2)
y - 13.00 = 1.14x - 2.28
y = 1.14x - 2.28 + 13.00
y = 1.14x + 10.72
Answer: D When the cab travels 0 miles, the total fee will be $10.00.
