Answer:
the cake that was left is 1 by 15
Step-by-step explanation:
The computation is shown below:
= sale - gave away
[tex]= \frac{2}{5} - \frac{1}{3}\\\\= \frac{6 - 5}{15} \\\\= \frac{1}{15}[/tex]
Hence, the cake that was left is 1 by 15
So the same is relevant and considered too
A group of friends wants to go to the amusement park. They have no more than $245 to spend on parking and admission. Parking is $9.25, and tickets cost $25.75 per person, including tax. Which inequality can be used to determine pp, the maximum number of people who can go to the amusement park?
Answer:
25.75x+9.25
Step-by-step explanation:
9.25 is the constant. You multiply the ticket by the amount of people to get ticket cost. Then you add ticket cost 9.25 to get final answer.
Inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We have been given that the group of friends has no more than $245 to spend on parking and admission.
And the parking is $9.25, and tickets cost $25.75 per person, including tax.
Let the number of people would be p who can go to the amusement park,
So the inequality that expresses the relationship is
⇒ 9.25 + 25.75 × p ≤ 245
Therefore, inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

How do I do Angle Measures of Parallel Lines
Answer:
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.

Step-by-step explanation:
Turn this fraction into a decimal. Show your work. 13/16.
Answer:
0.8125
Step-by-step explanation:
First , we all know that fraction is like division.
So I divided 13 by 16
Then I got my answer
Answer:
.812
Step-by-step explanation:
13/16 = .812
The fraction sign also means to divide, so all you do is 13/16 = .812
Work:
First, multiply 13 by 10^1 to get 130, then you can divide.
[tex]\sqrt[16]{130} \\[/tex] = 8.12. Finally, you take the 10^1 you did from 130 and divide 8.12 to get .812

In ΔHIJ, the measure of ∠J=90°, the measure of ∠I=72°, and JH = 1.2 feet. Find the length of HI to the nearest tenth of a foot.
Answer:
1.3
Step-by-step explanation:
Looking at the triangle, the first thing we can notice is that it is a right triangle, so we can use trigonometric ratios to solve for missing sides.
The side the problem is asking us to find is leg HI, which happens to be the hypotenuse of triangle HIJ.
We also know one side length: HJ= 1.2 ft, and one angle measure: ∠I=72°.
In these types of problems, there are two trigonometric ratios we can look to:
Sine or sin(x)= opposite/hypotenuseCosecant or csc(x)= hypotenuse/oppositeYou can actually use either of these to solve your problem, but for convenience let's use cosecant.
Cosecant of 72° will be equal to HI (the hypotenuse length) divided by HJ (the length of the opposite leg of angle I) Cosecant of 72° will be equal to HI divided by 1.2 (substitute the given length for HJ)1.05146222424 (plug csc(72°) into a calculator)=HI/1.2 1.05146222424*1.2=HI (multiply each side of the equation by 1.2) HI=1.26175466909 (simplify) HI≈1.3 (round the simplified number to the nearest tenth, as the problem requests)disclaimer: i'm not at all qualified to be teaching trigonometry haha (but i hope this helps you!!)
please please please let me know if i made any mistakes
I don’t understand it’s really confusing. This was due an hour ago please help I’m struggling!
Step-by-step explanation:
What you are dealing with is what we call special right triangles. There are two types of right triangles.
30-60-90 triangle- A special
right triangle with side length ratio as
[tex](a)(a \sqrt{3} )(2a)[/tex]
, where a is any positve number
45-45-90- a special right triangle which side length ratios are
[tex](a)(a)(a \sqrt{2)} [/tex]
where a is any positve number.
45 45 90 triangles is indicated by two congruent side measures( if the legs are congruent and it has a right angle, it is a 45-45-90.
30-60-90 triangles is indicated by a having at least two of the following angles given (30,60, and 90).
Shortcuts:
For a 45 45 triangle,
the legs are equal while the hypotenuse is the sqr root of 2 times than the legs.
Example, look at 1. The legs side length is 12 so our hypotenuse side length will be
[tex]12 \sqrt{2} [/tex]
For a 30-60-90 triangle, the side that is adjacent to the 30 and 90 degree measure sqr root of 3 times more than the horizontal leg.
the slanted side or the side which is adjacent to the 30 and 60 degree angle is twice the length of the horizontal leg or the side that is adjacent to the 60 and 90 degree.
Example, look at 3. We need to find x but we are given the horizontal side so just multiply sqr root of 3 to 12.
[tex]x = 12 \sqrt{3} [/tex]
[tex]1.12 \sqrt{2} [/tex]
2.Both equal
[tex]2.8 \sqrt{2} [/tex]
[tex]3.12 \sqrt{3} [/tex]
4. a=13
[tex]4.13 \sqrt{3} [/tex]
[tex]5.9 \sqrt{4} [/tex]

What is the perimeter of the square below?
Answer:
the perimeter is 44 inches
Step-by-step explanation:
because 4 × 11 is 44 and all the sides are equal
Answer:
44inches
Step-by-step explanation:
Since all of the sides are equal, you just need to multiply 11 with 4.
11x4=44
or
there are 4 sides and each side equals 11 so-
11+11+11+11=44

explain how the following diagram demonstrates the pythagorean theorem?
Answer:
the largest block represents the hypotenuse which would be c² the smallest can either be a or b and the block thats left over will be the letter you didn't use for the small block so in terms the blocks represents a²+b²=c²
[tex]\bold{a^2+b^2=c^2}[/tex] is indeed the Pythagorean theorem. It implies that adding the hypotenuse square as well as the two sides of a right triangle equals the hypotenuse square.
Calculating value by using the Pythagorean theorem:The smallest side of the triangle in this instance contains 36 squares, which equals [tex]\bold{6^2}[/tex]. The triangle's bigger side has 64 (or [tex]\bold{8^2}[/tex]) squares. You get 100 by multiplying 36 and 64, which is the same as [tex]\bold{10^2}[/tex]. Using the formula [tex]\bold{a^2+b^2=c^2}[/tex], you should arrive at [tex]\bold{6^2+8^2=10^2}[/tex].Find out more information about the Pythagorean theorem here:

Which ordered pair is the best estimate for the solution of the system of equations?
y=−34x−2y=x+6
a (−4.5,1.75)
b(−4.25,1.5)
c(−4.5,1.5)
d(−4.75,1.75)
Use the second equation. Replace x with the answer choices and if it equals the y value than that is the answer:
Y = x + 6
-4.5 + 6 = 1.5
The answer would be C. (-4.5,1.5)

If AB=4 feet & AD=10 feet & m
What is DC?
What is BD?
What is m
What is m
Answer:
1. DC = AB = 4 ft
2. BD = 10.80 ft
3. m<CED = [tex]90^{0}[/tex]
4. m<EBC = [tex]65^{o}[/tex]
Step-by-step explanation:
From the given quadrilateral,
Given: AB = 4 ft, AD = 10 ft and m<BAE = 65.
1. DC = AB = 4 ft (opposite sides of a parallelogram are equal)
2. Applying the Pythagoras theorem to ΔABD, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]BD^{2}[/tex] = [tex]4^{2}[/tex] + [tex]10^{2}[/tex]
= 16 + 100
= 116
BD = [tex]\sqrt{116}[/tex]
= 10.7703
BD = 10.80 ft
3. m<CED = [tex]90^{0}[/tex] (the diagonals bisects each other at right angle)
4. m<ABC + m<BAC + m<ACB = 180
90 + 65 + m<ACB = 180
m<ACB = 180 - 155
m<ACB = [tex]25^{0}[/tex]
So that,
m<BEC + m<EBC + m<ECB = 180
90 + m<EBC + 25 = 180
m<EBC = 180 - 115
m<EBC = [tex]65^{o}[/tex]
