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

A sphere has a radius of 12 inches. A second sphere has a radius of 9 inches. What is the difference of the volumes of the spheres?
The volume of the larger sphere is π
cubic inches greater than the volume of the smaller sphere.
Answer:
Solution given;
for sphere
radius [r]:12inches
another
radius [R]:9inches
Now
difference in volume of sphere:
volume of sphere of having radius [r-R]
=[tex] \frac{4}{3} πr³[/tex]-[tex] \frac{4}{3} πR³[/tex]
=[tex] \frac{4}{3} π[/tex](12³-9³)
= 1332π cubic inches
The volume of the larger sphere is ___1332__π cubic inches greater than the volume of the smaller sphere.
Is the function below linear or non linear? y = 5 + 3(x-4)
Answer:
Linear
Step-by-step explanation:
The rule is that linear equations must have exponents of 1 (a sloped line) or 0 A verticle or horizontal line). This function can be simplified to
y = 3x - 12 + 5 = 3x - 7 which is the standard form of a linear equation
y - mx + b where m is the slope and m is the y intercept.

Problem:
The Winter fest Race will be held in December. A course was planned that
required runners to run 20 kilometers (km.) The race organizers planned the
race in 3 parts. Part 1 of the course is 4,000 meters (m). Part 2 of the race
is 6,000 meters (m.) Tommy said that there is no need for the Part 3 and that
Part 1 and 2 are 20 km. He is incorrect. How many meters will be required
for Part 3
Answer:
10,000m
Step-by-step explanation:
1 kilometer is equivalent to 1,000 meters. Therefore, we can find out why Tommy was incorrect and how many meters will be required for part 3 by converting the meters in this question to kilometers.
4,000m = 4km
6,000m = 6km
4km plus 6km is equal to 10km, which is nowhere near 20km. To find out how many kilometers we need for part 3, we need to subtract the number of kilometers we already have (10km) from the total number we need for the whole race (20km).
20km – 10km = 10km
Since the question is asking us to give the answer in meters, we need to multiply 10km by 1,000.
10km = 10,000m
The answer is 10,000m.82.8 cm measured to the nearest tenth of a cm.
Answer:
80.0 cm

Miguel has a toolbox that measures 18 1/2 inches by 12 1/2 inches by 4 inches. Fill in the formula to find the volume of the toolbox
Answer:
925 cubic inches
Step-by-step explanation:
Miguel has a toolbox that measures 18 1/2 inches by 12 1/2 inches by 4 inches. Fill in the formula to find the volume of the toolbox
The toolbox is shaped as a Rectangular prism
The volume of a rectangular prism = Length × Width × Height
Hence,
Length = 18 1/2 inches
Width = 12 1/2 inches
Height = 4 inches
Volume of the toolbox =
18 1/2 inches × 12 1/2 inches × 4 inches
= 925 cubic inches

What is the equation in slope-intercept form
of the line that passes through the points
(-3, 10) and (3, 14)?
Answer:
C) y=2/3x+12
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(14-10)/(3-(-3))
m=4/(3+3)
m=4/6
simplify
m=2/3
y-y1=m(x-x1)
y-10=2/3(x-(-3))
y-10=2/3(x+3)
y=2/3x+6/3+10
y=2/3x+2+10
y=2/3x+12
How would you find the missing value? 15/4=5/x
15(4) = 5x
15(x) = 5(4)
15 14 =5+x
Using the intersecting chord theorem you multiply the two lengths of one line together to equal the multiplication of the two dimensions on the second line.
The answer would be 15(4) = 5x

"-3x" + 5 < "-10" Inequality 2: 7x + x - 4 > 28 Which of the following values makes BOTH inequalities TRUE? Select all that apply! 12 "-5" −152 "-8.25" 23 48 325
Answer:
12, 23, 48, 325
Step-by-step explanation:
So, when given two inequalities and asked to find the values that make both true, it is considered a system of equations. To solve a system of equation, you have to graph the inequalities and find where they intersect.
Inequality 1:
(-3x) + 5 < (-10)
Inequality 2:
7x + x - 4 > 28
simplifies to: 8x - 4 > 28
When graphed, the inequalities don't intersect, but rather have a similar shaded area overlapping from the point of 5 and greater.
Answers that apply from given list would be:
12, 23, 48, 325
Noah says, "If I try to write 100 expanded, it should have zero factors that are 10, so it must be equal to 0." Do you agree? Why or why not?
Answer:
Disagree
Step-by-step explanation:
10^0
According to the laws of indices, anything raised to the power of 0 will equate to 1. Therefore, based on this established mathematical principle, Noah's assertion about 10^0 being equal to 0 is false.
Hence, I disagree.

A lenght of wire is bent to make a square of side 3.2 cm a: what is the length of wire in the square B: if the wire is silver costing 50 naira per centimetre what is the cost of the square C: 20 of the squares are linked together to make a necklace what does it cost to make the necklace
Answer:
12.8cm
640 naira
12,800 naira
Step-by-step explanation:
length of the wire is equal to the perimeter of a square
perimeter of a square = 4 x length
4 x 3.2 = 12.8 inches
cost of the square = length of the wire x 50
12,8 x 50 = 640
20 x 640 = 12800

Solve the equations for x:
x^2+nx-mx-nm=0
Answer:
x = [(m - n +/-√ (n^2 + m^2 + 2nm)]/2.
Step-by-step explanation:
x^2+nx-mx-nm=0
x^2 + (n - m)x - nm = 0
Using the quadratic formula:
x = [-(n - m) +/- √((n - m)^2 - 4*-nm)) / 2
= [(m - n +/- √ (n^2 + m^2 - 2nm + 4nm)]/2
= [(m - n +/-√ (n^2 + m^2 + 2nm)]/2

Answer:linear
Step-by-step explanation:
it is a straight line
The best-fitting regression model for the scatterplot is linear. Thus, the correct answer is an option (A).
As per the given figure, the data points on a scatterplot, with the dependent variable (y-axis) plotted against the independent variable (x-axis).
Looking at the general pattern of the data points on the scatterplot.
Here, they follow a roughly linear trend.
This means that the data points roughly form a straight line or a curve that looks like a straight line.
Thus, the best-fitting regression model for the scatterplot is linear.
