A baker had 3 1/4 pounds of apples. she used 3/4 to make an apple pie. How many pounds of apples does she have left
Answer:
2 1/2
Step-by-step explanation:
3 1/4 - 3/4 =2.5 which simplify's to 2 1/2
The number of pounds of apples that she has left will be 13/16 pounds.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
A baker had 3 ¹/₄ pounds of apples. she used 3/4 to make an apple pie.
Convert the mixed fraction number into a fraction number. Then we have
3 ¹/₄ = 13/4
The number of pounds of apples that she has left will be given as,
⇒ 13/4 - (13/4)(3/4)
⇒ 13/4 - (39/16)
⇒ (52/16) - (39/16)
⇒ (52 - 39) / 16
⇒ 13/16 pounds
The number of pounds of apples that she has left will be 13/16 pounds.

A city map is placed on a coordinate grid. The post office is located
at the point A(3, 8), the library is located at the point B(15,9), and
the fire station is located at the point C(21, 9.5) What is the ratio of
the length of AC to the length of BC?
The length of a segment is the number of units on the segment.
The ratio of line segment AC to line segment BC is 3 : 1
The coordinate points are given as:
[tex]\mathbf{A = (3,8)}[/tex]
[tex]\mathbf{B = (15,9)}[/tex]
[tex]\mathbf{C = (21,9.5)}[/tex]
The length of each segment will be calculated using the following distance formula
[tex]\mathbf{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]
So, we have:
[tex]\mathbf{AC = \sqrt{(3 - 21)^2 + (8 - 9.5)^2}}[/tex]
[tex]\mathbf{AC = \sqrt{326.25}}[/tex]
Also, we have:
[tex]\mathbf{BC = \sqrt{(15 - 21)^2 + (9 - 9.5)^2}}[/tex]
[tex]\mathbf{BC = \sqrt{36.25}}[/tex]
The ratio of AC to BC is represented as:
[tex]\mathbf{AC : BC = \sqrt{326.25}:\sqrt{36.25}}[/tex]
Divide through by [tex]\sqrt{36.25[/tex]
[tex]\mathbf{AC : BC = \sqrt{9} : \sqrt{1}}[/tex]
Evaluate square roots
[tex]\mathbf{AC : BC = 3 : 1}[/tex]
Hence, the ratio is 3 to 1

Consider the line 4 x + 9 y = 8 . What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
Answer:
Parallel line: -4/9 Perpendicular line: 9/4
Step-by-step explanation:
This linear equation is written in standard form: Ax + By = C. First, we isolate the y variable to get the equation: y = -4/9x + 8/9. Now we notice that the slope of this line is -4/9. Parallel lines have the same slope, so the slope of the line parallel to this one is also -4/9. The slope of a perpendicular line is the negative reciprocal of the slope of this line, so the slope of a perpendicular line is 9/4.
a right triangle has 13 and 8 feet long each find the length of the hypotenuse
Answer:
15.26
Step-by-step explanation:
By using a^2+b^2=c^2, we can plot the numbers into the equation, 8^2+13^2=c^2. Then answering the exponents, it will equal 64+169=c^2. Add that together to get 233=c. Lastly, we have to square-root 233, which equals 15.26. Hope this helped!

Triangle A and Triangle B are right triangles.
Triangle A has a height of 8 meters and a base of 6 meters.
Triangle B has a height that is one unit greater than triangle A and a base that is one unit less.
What is the measure of the hypotenuse of triangle A? Show your work.
Determine if the hypotenuse of triangle B has the same hypotenuse as triangle A. Justify your solution.
I. The measure of the hypotenuse of triangle A is equal to 10 meters.
II. The measure of the hypotenuse of triangle B is equal to 10.30 meters.
Given the following data:
Height A = 8 metersBase A = 6 metersTo determine the measure of the hypotenuse of triangle A, we would apply Pythagorean's theorem since the is a right triangle:
Mathematically, Pythagorean's theorem is given by the formula:
[tex]C^2 = A^2 + B^2\\\\C^2 = 6^2 + 8^2\\\\C^2=36+64\\\\C^2 = 64+36\\\\C^2=100\\\\C=\sqrt{100}[/tex]
Hypotenuse, C = 10 meters.
For Triangle B:
Triangle B has a height that is one (1) unit greater than triangle A:
Height B = 8 + 1 = 9 meters
Triangle B has a base that is one (1) unit less than triangle A:
Base B = 6 - 1 = 5 meters
To find the hypotenuse B:
[tex]C^2 = A^2 + B^2\\\\C^2 = 5^2 + 9^2\\\\C^2=25+81\\\\C^2=106\\\\C=\sqrt{106}[/tex]
Hypotenuse, C = 10.30 meters
From the above calculations , we can deduce that the measure of the hypotenuse of both Triangle A and Triangle B are different.
