Answer:
1.21
Step-by-step explanation:
5.26 - 3.64 = 1.62
1.62 ÷ 2 because the difference between 3 and 5 is two, the mass of one apple is 0.81 because 1.62 ÷ 2 = 0.81
so now we know one apple weights 0.81
if we multiply that 0.81 x 3 it will equal 2.43, so now the three apples alone wiegh 2.43...so now we look at the total weight of the whole basket with three apples, which is 3.64,
3.64 - the weigth of the apples (2.43)
3.64 - 2.43 = 1.21
the basket alone wieghts 1.21

Suppose that the annual rainfall in Ferndale, California, is known to be normally distributed, with a mean of 35.5 inches and a standard deviation of 2.5 inches. About 2.4% of the years, the annual rainfall will exceed how many inches? (Round your answer to one decimal place.)
The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.
What is the average annual rainfall?Generally, the equation for the probability is mathematically given as
[tex]P( X < x) = p( Z < x - \mu / \sigma)[/tex]
Therefore
[tex]P( X > x) = 0.021[/tex]
[tex]P( X < x ) = 1 - 0.021\\\\\p( X < x) = 0.979[/tex]
[tex]P( Z < x - \mu / \sigma) = 0.979[/tex]
The z score for the probability of 0.979 is 2.034, according to the table of z values.
[tex]x - \mu / \sigma \\\\x= 2.034[/tex]
In the given equation, replace the values of mu and sigma with their respective values, and then solve for x.

two vertices are 3x+10 and x+60 find x
The value of x such that the vertices 3x + 10 and x + 60 are equal is 25
What are vertices?Vertices are the endpoints or corners of a shape (such as triangle, square, rectangle and related shapes)
How to determine the value of x?The two vertices are given as:
3x + 10 and x + 60
The condition on the two vertices are not given.
So, we assume that the vertices are equal (as in the base angles of an isosceles triangle)
So, we have the following equation
3x + 10 = x + 60
Subtract x from both sides of the equation
2x + 10 = 60
Subtract 10 from both sides of the equation
2x = 50

Step-by-step explanation:
The formula of the volume of a cone: [tex]V = \pi r^2\frac{h}{3}[/tex]
--> V = Volume, r = Radius, h = Height
In other words, the volume of the cone is the area of the circle x height x 1/3 x pi.

Given the graph of g(x), describes the transformation of the parent function f(x)=2^x.
If the parent function is transformed by:
Shifting 1 unit to the right, the image function is given by g(x) = (x - 1)²Shifting 1 unit to the left, the image function is given by g(x) = (x + 1)².Shifting 1 unit downward, the image function is given by g(x) = x² - 1.Transformation of the parent function.The graph of the parent function is a parabolic curve which opens in the y-axis direction and with its vertex at the origin on a cartesian coordinate.
By critically observing the graph of this parent function [f(x) = x²], we can infer and logically deduce that the transformed curve is a downward opening parabola which has a vertex at (-5, -2).

1. How much percent more than the cost price should a shopkeeper mark his goods so that after allowing a discount of 25% on the marked price, he gains 20% ?
2. When a bicycle is sold at marked price, a profit of 20% is earned by the seller. If a discount of 5% is allowed, the profit is only Rs. 180 earned by the seller. How much did the seller pay for the bicycle?
Answer:
1. 60%
2. He paid Rs. 1285.71
Step-by-step explanation:
1.
He buys an item for x.
He sells the item with a 25% of the marked price, and he still makes a 20% profit over his cost x.
He must sell for x + 20% of x which is the same as 1.2x.
Let the markup be y%.
Since he gives a 25% discount over the marked price, he sells for 75% of the marked price.
0.75(x + y% of x) = 1.2x
0.75(x + xy/100) = 1.2x
x + xy/100 = 1.6x
Divide both sides by x.
1 + y/100 = 1.6
Multiply both sides by 100.
100 + y = 160
y = 60
Remember that y is in percent, so the markup must be 60%.
Check:
He buys an item for $10.
He applies a markup of 60%. 1.6 × $10 = $16.
He has a price of $16 for this item.
Now he gives a 25% discount. That means the discounted price is 75% of the marked price.
75% of $16 = $12
He sells at a 25% discount for $12.
Compare the actual selling price after the 25% discount with this cost.
$12 compared to $10.
$12/$10 = 1.2 = 120%
Since he sells for 120% of the original price, the markup is 20% which is what he wanted.
2.
The cost to the seller is x.
If he sells it at a 20% profit, then he sells it for 1.2x
Now he gives a discount of 5%, so the final selling price after discount is
0.95(1.2x)
The profit is the difference between what he sold it for, 0.95(1.2x), and what he bought is for, x, and it is Rs. 180.
0.95(1.2x) - x = 180
1.14x - x = 180
0.14x = 180
x = 1285.71
Answer: He paid Rs. 1285.71

A rectangle has corners E, F, G, D, starting from top left and going clockwise. Point H is halfway between E and F. 2 lines are inscribed in the rectangle. One line goes from D to H and another goes from H to G. Angle E D H is (5 x) degrees and angle H D G is (4 x) degrees. Angles E D G and F G D are right angles. What is the measure of Angle EDH? 10° 40° 50° 90°
The measure of Angle EDH = 50°.
How to estimate the measure of Angle EDH?The angle EDH exists given as 5x° and the angle HDG exists given as 4x°. The angles EDG and FGD exist at right angles. That signifies both angles exist equivalent to 90°.
Angle EDH = 5x°
Angle HDG = 4x°
Angle EDG = 90°
5x + 4x = 90
9x = 90
Divide both sides by 9
x = 90/9
x = 10°
Angle EDH = 5x = 5 × 10 = 50°
The measure of Angle EDH = 50°.

⇒ 6x - 4 + 112 = 180
⇒ 6x + 108 = 180
⇒ 6x + 108 - 108 = 180 - 108
⇒ 6x = 72
⇒ 6x ÷ 6 = 72 ÷ 6
⇒ x = 12
