As a block of ice melts, its weight changes from 1 3/4 lb to 1/4 lb. This change takes 1/4 h. The ice melts at a constant rate. At what rate does the weight of the ice change?
Answer:-You should have these values backwards like:-
=> 1/34 lb is less than 1/4 lb.
Next:-
We're gonna find a specific common denominator,
Then we get: (17/68 - 2/68)/(1/4) = 60/68 = 15/17 lb/hour

which expression represents the difference of (5x-3y) and (8x+8y)?
Answers
Given:
The expressions are:
[tex](5x-3y)[/tex] and [tex](8x+8y)[/tex]
To find:
The difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex].
Solution:
Difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is written as:
[tex]Difference=(5x-3y)-(8x+8y)[/tex]
On simplification, we get
[tex]Difference=5x-3y-8x-8y[/tex]
[tex]Difference=(5x-8x)+(-3y-8y)[/tex]
[tex]Difference=-3x-11y[/tex]
Therefore, the difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is [tex]-3x-11y[/tex].
One of the flights was 350 miles and its residual was -
105.00. What was the fare for this flight?
Based on data taken from airline fares and distances
flown, it is determined that the equation of the least-
squares regression line is ý = 102.50 +0.65x, where
ý is the predicted fare and x is the distance, in miles.
O $102.50
O $435.00
O $225.00
O $330.00
Answers
Answer:
O $225.00
Step-by-step explanation:
Given that
The one of the flight was 350 miles
And, its residual is 105
The regression line is y = 102.50 + 0.65x
where
y denotes the expected fare
And, x denotes the distance
We need to find out the fair of the flight
So,
y = 102.50 + 0.65 (350)
= 330.00
Now the fare is
= 330 - 105
= 225
Answer:
(C) 225 Is correct.
Predicted cost - residual = answer
y= 102.50 + .65(35)
330 - 105 = 225

C. y+7=−611(x−7)
D. y−7=−611(x+7)
Answers
Answer:
D) y-7=-6/11(x+7)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-7)/(4-(-7))
m=-6/(4+7)
m=-6/11
y-y1=m(x-x1)
y-7=-6/11(x-(-7))
y-7=-6/11(x+7)
y=-6/11x-42/11+7
y=-6/11x-42/11+77/11
y=-6/11x+35/11

Quantity of flour needed to make 20 pancakes =
Then , number of pancakes that can be made from 1 cup of floor :-
.
Therefore , 12 pancakes can be made from 1 cup of floor .
Solution (b) :-
Number of pancakes that can be made with 1 cup of flour = 12 pancakes
Number of pancakes that can be made with 9 cups of flour :-
= 9 × 12
= 108 pancakes
Therefore , I can make 108 pancakes with 9 cups of flour .
Solution (c) :-
Yes , I have enough flour to make 100 pancakes . I say this because :-
With one cup of flour I can make = 12 pancakes
With 9 cups of flour I can make =
= 9 × 12
= 108 pancakes
As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .

Callie wrote this number to show the change in volume of a water cooler after practice. -9/10
What’s equivalent to what Callie wrote
Answers
ONLY one value must have the negative sign, otherwise it will be a positive value
The correct option is option B that is [tex]\frac{-9}{10}[/tex] is the same number as Callie has written to show the change in volume.
What is a fraction ?
A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.
It is given that Callie wrote a number to show the change in volume of a water cooler after practice which is :
= [tex]\frac{-9}{10}[/tex]
Let's check from the given options which is the correct one.
A)
- [tex]\frac{9}{-10}[/tex]
if we multiply and divide by -1 then we find that the given fraction is equal to :
= [tex]\frac{9}{10}[/tex]
This is not equal to what Callie has written.
B)
[tex]\frac{-9}{10}[/tex] is the same number as Callie has written to show the change in volume. So , this is a correct option.
C)
[tex]\frac{-9}{-10}[/tex] will be equal to [tex]\frac{9}{10}[/tex]. This is because there is negative sign in both numerator and denominator of the fraction , and they will get cancelled. So, this option is not correct.
D)
[tex]\frac{9}{10}[/tex] is not equal to [tex]\frac{-9}{10}[/tex]. To equal both we need to multiply [tex]\frac{9}{10}[/tex] by -1. Thus this option is also not correct.
Therefore , the correct option is option B that is [tex]\frac{-9}{10}[/tex] is the same number as Callie has written to show the change in volume.

This question is incomplete, the complete question is;
A screening examination was performed on 250 persons for factor X, which is found in disease Y. A definitive diagnosis for disease Y among the 250 persons had been obtained previously. The results are charted here:

Positive for Factor X 40 60
Negative for Factor X 10 140
a) Based on the information provided, The sensitivity of this test is expressed as: A. 30%. B. 80%. C. 56%. D. 70%. E. 7%.
b) Based on the information provided, The specificity of this test is expressed as: A. 30%. B. 80%. C. 56%. D. 70%. E. 7%.
Answer:
a)
The sensitivity of this test is expressed as 80%
Option B) 80% is the correct answer.
b)
The specificity of this test is expressed as 70%
Option D) 70% is the correct answer.
Step-by-step explanation:
Given the data in the question;
Test Results Disease Present Disease Absent
Positive for Factor X 40 60
Negative for Factor X 10 140
Number of persons affected by disease with positive factor of X = 40
Number of persons with negative factor of X without the disease = 140
Total number of persons affected by the disease = 40 + 10 = 50
Total number of persons not affected by the disease = 60 + 140 = 200
a) Sensitivity of the Test;
Sensitivity = [( Number of persons affected by disease with positive factor of X ) / ( Total number of persons affected by the disease )] × 100
we substitute
Sensitivity = [ 40 / 50 ] × 100
Sensitivity = 0.8 × 100
Sensitivity = 80%
Therefore, The sensitivity of this test is expressed as 80%
Option B) 80% is the correct answer.
b) The specificity of the test;
Specificity = [ ( Number of persons with negative factor of X without the disease) / ( Total number of persons not affected by the disease ) ] × 100
we substitute
Specificity = [ 140 / 200 ] × 100
Specificity = 0.7 × 100
Specificity = 70%
Therefore, The specificity of this test is expressed as 70%
Option D) 70% is the correct answer.

Step-by-step explanation:

Cylinders are described with dimensions as
Diameter and Height
Say the diameter is
D= 10m
and Height is
H=20
Hence the radius is
R= D/2= 10/2= 5 m
Therefore the volume is gotten as
V= πr^2h
V= π*5^2* 20
V= π*25*20
V= 500π m^3
Hence the volume is 500π m^3

a triangle has side lengths 10, 16, and 11. is the triangle actue, obtuse, or right?
Answers
Answer:
Obtuse
Step-by-step explanation:
a^2 + b^2 = c^2
10^2 + 11^2 = 16^2
100 + 121 = 256
221 = 256
221 < 256
A triangle has side lengths 10, 16, and 11. is the triangle is obtuse.
Name three types of triangles based on angles?Triangles can be classified into three types with respect to their interior angles which are:
1. Acute-angled
2. Obtuse-angled
3. Right-angled
Acute Triangle
An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.
Obtuse Triangle
Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.
Right Triangle
A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse.
Three given sides are 10, 11, 16
Let a = 10, b = 11, c = 16
then, [tex]a^{2} +b^{2} = 10^{2} +11^{2}[/tex]
= 100 + 121
= 221
and [tex]c^{2} = 16^{2} =256[/tex]
Since, [tex]a^{2} +b^{2} < c^{2}[/tex]
Thus, given triangle is obtuse.

What is the equation of the line that passes through (4, 3) and (-4,-1)?
Answers
Answer:
[tex]\implies y = \dfrac{1}{2}x + 1 [/tex]
Step-by-step explanation:
Given :-
Two points (4,3) and (-4,-1)And we need to find out the equation of the line passing through the given two points .So here we can use the two point form of the line as ,
[tex]\implies (y - y_1) = \dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]
Let us take that ,
[tex](x_1,y_1)=(4,3) [/tex][tex](x_2,y_2)=(-4,-1)[/tex]Now substitute the respective values ,
[tex]\implies (y -3) =\dfrac{3+1}{4+4}(x-4) \\\\\implies y - 3 =\dfrac{4}{8}(x-4) \\\\\implies y -3=\dfrac{1}{2}(x-4) \\\\\implies y -3=\dfrac{1}{2}x - 2 \\\\\implies y = \dfrac{1}{2}x +3-2\\\\\implies y = \dfrac{1}{2}x + 1 [/tex]
Hence the correct option is (2) .
