All books in a store are being discounted by 40%. let x represent the regular price of any book in the store which expression describes the sale price of a book ?

Answers

Answer 1

To find the sale price we can set up a proportion. 25/100 = x/48. We keep the 100 and 48 both on the bottom of the fraction since they represent the "whole". x represents the discount off the full price of the dress. To solve this proportion, we cross multiply, yielding 48 * 25 = 100x. Alternatively, if you notice that 25/100 ...

Abigail flipped a coin 20 times, and it landed with heads facing up 13 times. What percent of the coin flips landed with heads facing up.

Answers

65% of the coins flipped landed with heads facing up because 13 were faced up out of 20.

Divide:
13/20=0.65=65%

Hope this helped☺☺

Final answer:

The percentage of times Abigail's coin landed on heads is 65%, which is found by dividing the number of successful outcomes (head flips) by the total number of trials (total flips) and then multiplying by 100.

Explanation:

The calculation you're asking for is one of percentage, which is a basic concept in mathematics often related to probability and statistics. We determine the percentage of times the coin landed on heads by dividing the number of successful outcomes (the coin landing on heads) by the total number of trials (the total coin flips), and then multiplying that result by 100 to convert the decimal to a percentage.

Here's a step-by-step way to do it:

Firstly, count the number of times the coin landed on heads, which is 13. Next, count the total number of coin flips, which is 20. Divide the number of successful outcomes (head flips) by the total trials (total flips). In this case, 13 ÷ 20 = 0.65. Finally, to convert this decimal to a percentage, multiply by 100. So, 0.65 × 100 = 65%.

So, 65% of Abigail's coin flips landed with heads facing up.

Laura bought a square canvas to paint a picture of her cat one side measured 22 centimeters what is tha area of the canvas

Answers

Hi there!

To start, squares are a shape in which all of its sides are congruent to one another. Knowing the length of one side would mean that you would know the length of all the other sides.

Because you know that one side measures 22 cm, you can conclude that all the other sides of the square are also at a length/width of 22 cm.

Next, you will find the area of the square.

Because the area formula is Area=Length * Width, you can easily find the area of the square by multiplying 22*22 since the length and width of any square is the same.

When you simplify 22*22, you should get 484.

Therefore, the area of the square canvas would be 484 cm squared.

The tank shown is made of steel. It does not have a cover. Find the area of steel sheet used to make the tank.

Answers

The perimeter of the top is
.. 2*(6.5 ft +28 ft) = 69 ft
so the lateral area of the tank is
.. 69 ft * 13 ft = 897 ft^2

The area of the bottom is
.. 6.5 ft * 28 ft = 182 ft^2

The total area is 897 ft^2 +182 ft^2 = 1079 ft^2.

the area has to be found step by step for this one since it doesn't really have a top part. so you say 6.5*28= 182 ft squared
then 6.5 * 13 * 2= 169 ft squared
and then find the last two sides which are
28 * 13= 364 ft squared
Finally you have to add all the above areas so, 182+169+364= 717 ft squared

What is circumference of circle?

"It is the length of the boundary of the circle."

Formula for the circumference of circle:

[tex]c = 2\times \pi \times r[/tex]

What is rate?

"It is the distance covered per unit times."

For given question,

A circular garden has a circumference of 44 yards.

⇒ C = 44

⇒ 2 × π × r = 44

⇒ 2 × r = 14.01 yards

We know, the diameter of the circle is d = 2 × r

This means, the diameter of the circular ground is 14.01 yards.

here, the rate (s) = 7 yards per hour

Using the formula of rate,

[tex]\Rightarrow s=\frac{d}{t}\\\\\Rightarrow 7=\frac{14.01}{t}\\\\ \Rightarrow t= 2.001\\\\ \Rightarrow t\approx 2~~hours[/tex]

Therefore, it will take him almost 2 hours to dig across the garden.

The points (10, 6) and (7, u) fall on a line with a slope of -4/3. what is the value of u?

u=

Answers

Answer:
u = 10

Explanation:
The slope of the lone can be calculated as follows:
slope = (y2-y1) / (x2-x1)

We are given:
slope = -4/3
point (10,6) representing (x1,y1)
point (7,u) representing (x2,y2)

Substitute with the givens in the above equation and solve for u as follows:
slope = (y2-y1) / (x2-x1)
-4/3 = (u-6) / (7-10)
-4/3 = (u-6) / -3
4/3 = (u-6) / 3
3*4 = 3*(u-6)
4 = u-6
u = 4+6
u = 10
