Answers
Answer:1:2
Step-by-step explanation:
it is this answer because you have 2 circles for 4 triangles, you can simplify that by dividing each number by 2 and you get 1 and 2
Answer:
1:2
Step-by-step explanation:
it would originally be 2:4 But both are divisible by 2 so they simplify down to 1:2........2÷2=1 and 4÷2=2 since the ratio has to be circles to triangle the 1 goes first then the 2

x=43/2
Answer:
x= -43/2
Step-by-step explanation:
\(\frac{1}{5}x +\frac{3}{10} =-4\)
To add or subtract fractions, we need to have the same denominator. We can do that by cross multiplying : \(\frac{1}{5}x\) + \(\frac{3}{10}\) for the numerator, and multiply both denominators together to find our common denominator.
\(\frac{10x+15}{50}=-4\)
Now, cross multiply to solve for x.
\(10x+15=-200\)
\(10x=-215\)
\(x=-\frac{43}2}\)

sophie's favorite number is a two-digit number. if she reverses the digits, the result is $45$ less than her favorite number. the sum of the digits in her favorite number is $11$. what is sophie's favorite number?
Answers
Sophie's favorite number is 83
We have that;
A two-digit number is Sophie's preferred number. Her favorite number is 45 less when the digits are in reverse. Her favorite number has digits that add out to 11 in total.
To get Sophie's favorite number, we need to assume the case as;
Let,
⇒10x + y = 10y + x + 45
x + y = 11
y = 11-x
⇒10x + 11 - x = 10(11 - x) + x + 45
10x + 11 - x = 110 - 10x + x + 45
9x + 11 = 155 - 9x
18x + 11 = 155
18x = 144
x = 8
Therefore, y = 11 - 8
y = 3
Sum = x + y = 8 + 3 = 11
Hence, the given condition is satisfied.
Sophie's favorite number is 83.

what is the answer to 5x-4y=3
Answers
Answer: we need to get the values of x and y
x=(4y+3)/5
y=(5x-3)/4
Step-by-step explanation:
let us consider the quation 5x-4y=3
then on adding 4y on both sides it becomes:
5x=3+4y
this equation is in standard form
divide by 5 on both sides
it becomes
x=(3+4y)/5
in the similar way subtract 5x on both sides
then we get -4y=3-5x
it becomes: 4y=5x-3
y=(5x-3)/4
Step by step
We can solve x and y in standard form by substituting zero (0) for x to solve for y and (0) for y to solve x
5(0) -4y = 3
Simplify
-4y = 3
Divide both sides by -4 to solve for y
-4/-4 y = 3/-4
Simplify
y = -3/4
5x -4(0) = 3
Simplify
5x = 3
Divide both sides by 5 to solve for x
5/5 x = 3/5
Simplify
x = 3/5

A line has the equation y= 1/3x-5 find the equation of a parallel line passing through (3,2)
Answers
Answer:
y = (1/3)x + 1
Step-by-step explanation:
A parallel line has the same slope as the reference line. This means the new equation would have a slope of (1/3). The y-intercept, -5, needs to be different. But since the line needs to pass through point (3,2), we need a value of b that will cause that to happen.
We can start with y = (1/3)x + b. As long as b is not -5, the line will be different and parallel. To force it through point (3,2), just enter those values and solve for b:
y = (1/3)x + b
2= (1/3)*3 + b
2 = 1 + b
b = 1
The equation becomes y = (1/3)x + 1.

(a)A line through (2,1) meets the curve x²-2x-y=3at A (-2,5)and at B. Find the coordinates of B
(b) A(3,1) lies on the curve (x-1)(y+1)=4. A line through A perpendicular to x+2y=7 meets the curve again at B. Find the coordinates of B.
Answers
The slope of the line passing through these two points is:
m = (y2 - y1) / (x2 - x1) = (1 - 5) / (2 - (-2)) = -4/4 = -1
Using the point-slope form of the equation of a line, the equation of the line passing through A and (2,1) is:
y - 5 = -1(x + 2)
y - 5 = -x - 2
y = -x + 3
To find the coordinates of point B, we need to solve the system of equations formed by the equation of the line and the equation of the curve:
x² - 2x - y = 3
y = -x + 3
Substituting the second equation into the first, we get:
x² - 2x - (-x + 3) = 3
x² - x - 6 = 0
Solving for x using the quadratic formula, we get:
x = (1 ± √(1 + 24)) / 2 = 3 or -2
When x = 3, y = -x + 3 = 0, which means that point B is (3,0).
When x = -2, y = -x + 3 = 5, which means that point B is (-2,5).
Therefore, the coordinates of point B are (3,0) and (-2,5).
(b) We know that point A (3,1) lies on the curve (x-1)(y+1)=4.
Substituting x=3 and y=1 into this equation, we get:
(3-1)(1+1) = 4
4 = 4
Therefore, point A satisfies the equation of the curve.
We need to find the equation of the line passing through point A that is perpendicular to the line x+2y=7.
The slope of the line x+2y=7 is:
m = -1/2
The slope of a line perpendicular to this line is the negative reciprocal, which is:
m' = 2
Using the point-slope form of the equation of a line, the equation of the line passing through A(3,1) with slope 2 is:
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5
To find the coordinates of point B, we need to solve the system of equations formed by the equation of the line and the equation of the curve:
(x-1)(y+1) = 4
y = 2x - 5
Substituting the second equation into the first, we get:
(x-1)(2x-4) = 4
2x³ - 6x² + 4x - 5 = 0
We can use numerical methods to solve this cubic equation to get the value of x, and then substitute it back into the equation y = 2x - 5 to get the value of y. One possible solution is:
x ≈ 2.632
y ≈ -0.736
Therefore, the coordinates of point B are approximately (2.632, -0.736).
Erin buys 3 packs of potatoes costing £2 each, 4 packs of carrots for £2 per pack, and 4 turnips costing 90p each. If she pays with a £20 note, how much change would she get in pounds, £?
Answers
Answer: £2.4
Step-by-step explanation:
From the question, Erin buys 3 packs of potatoes costing £2 each, 4 packs of carrots for £2 per pack, and 4 turnips costing 90p each.
Total cost of potatoes = 3 × £2 = £6
Total cost of carrots = 4 × £2 = £8
Total cost of turnips = 4 × 90p = £360p = £3.6
The total cost of things bought by Erin will now be:
= £6 + £8 + £3.6
= £17.6
If she pays with a £20 note, she will collect a change of:
= £20 - £17.6
= £2.4
= 2 pounds, 40 pennies.
The digits in the product of 0.48 and a decimal number between 350 and 400 are 182136. explain how to correctly place the decimal point without knowing the other factor. then place the decimal point in the product
Answers
The right way to write digit 182136 without knowing the other factor is by; moving the decimal points 3 places to the left.
What is the explanation for the above?It is given that the digits in the product of 0.48 and a decimal number between 350 and 400 are 182136. Note that 0.48 is simply 48/100.
Hence, consider the decimal number between 350 and 400. The number will include one decimal place, so if it's 350.1, we may express it as 3501/10.
When we multiply 48/100 by 3501/10, the denominator is 1000, which is three decimal points to the left of the result.
As a result, the right method to express the answer supplied to us is 182.136, which was accomplished by shifting the decimal point three spaces to the left.

Submit
Answers
The perimeter of the triangle is 170 inches.
How to calculate the valueTo solve for the perimeter, we first need to find the length of the perpendicular height. We can do this using the sine function:
sin(35°) = 46/x
x = 46/sin(35°) = 65 inches
Now that we know the length of the perpendicular height, we can find the length of the base of the triangle using the cosine function:
cos(35°) = 65/x
x = 65/cos(35°) = 75 inches
The perimeter of the triangle is the sum of the lengths of the three sides, so the perimeter is:
P = 65 + 75 + 30

This means that the sheets of metal are parallel to each other and that their relationship is one of parallelism. This parallelism is necessary so that the roof can maintain its structure and be waterproof.
The relationship between sheets of metal on a roof is one of parallelism. This is because each sheet must be perpendicular to the top line of the roof in order to maintain the structure and be waterproof. In order for the roof to remain secure and waterproof, the sheets must be parallel to each other. This parallelism is necessary in order for the roof to form one complete structure and for the sheets to remain secure. Without the parallelism of the sheets, the roof would be unable to maintain its structure and could easily be damaged by wind and rain.
