Answer:
D - T-H is negative
Step-by-step explanation:
So lets go through what we know:
M is on the left side of 0, so M is negative.
A is also one the left side of 0, so A is negative.
T is on the right side of 0, so T is postive
H is also on the right side of 0, so H is postive
Lets go through each answer and see if it is accurate or not:
The sum of M and H is postive.
With what we know, M is negative and H is postive.
Looking at the graph, we can see that M is farther to the left than H is to the right.
So this means that M is a larger negative than H is postive, meaning when we add them together, the answer will be negative, not postive.
Next we have the answer to A divided by H is negative
We know A is negative, and M also negative
Remember, a negative divided or multiplied by a negative is postive.
This is not what our answer states, as it says it should be negative.
So next off, we have the product of H and A is postive.
Product means multipication.
A is negative and H is postive
Since it is multipication, and we know a negative and postive make another negative, this would make it incorrect
The answer states it must be postive, but this is negative.
Finally we have the answer as T-H is negative.
We see that T is postive, and H is postive.
T is less than H is, so when you subtract H from T, you would get a negative.
So D is the answer
Hope this helps!

Kevin drew a diagonal inside a quadrilateral. He realizes the it always make 2 congruent isosceles triangleso. What kind of quadrilateral did Kevin use to draw the triangles ?
Answers
Answer:
The square is the quadrilateral.
Step-by-step explanation:
A quadrilateral is a 2 dimensional geometric shape. It has four sides which may be or may not be equal.
If a quadrilateral is a square and we make its diagonal so that we get two triangles.
These two triangles are isosceles triangle as the two sides are equal and the square has four equal sides and the triangles are congruent to each other.
here, the triangles ABC and ADC are congruent and isosceles.

So we multiply (3x - 4y) by (-2x + 5y - 6)
So the solution will be
3x(-2x + 5y - 6) - 4y(-2x + 5y - 6)
Note: don't forget that there are positive signs and negative signs in the equation
-6x² + 15xy - 18x + 8xy - 20y² - 24y

The Park Protectors is a group of elementary students and teachers from 3232 schools who pick up trash at local parks. The line plot shows the tons of trash they picked up this year.
Answers
Answer:
[tex]Each = \frac{15}{128}[/tex]
Step-by-step explanation:
Given
See attachment for line plot
Required
Determine the total trash picked
The data on the line plot can be represented as:
[tex]Trash \to Schools[/tex]
[tex]\frac{1}{8} \to 6[/tex]
[tex]\frac{1}{4} \to 8[/tex]
[tex]\frac{1}{2} \to 2[/tex]
[tex]1 \to 0[/tex]
The total trash picked is:
[tex]Total = \frac{1}{8} * 6 + \frac{1}{4} * 8 + \frac{1}{2} * 2 + 1 * 0[/tex]
[tex]Total = \frac{3}{4} + \frac{8}{4} + 1+0[/tex]
Take LCM
[tex]Total = \frac{3+8+4+0}{4}[/tex]
[tex]Total = \frac{15}{4}[/tex]
The total picked by each school is:
[tex]Each = \frac{Total}{32}[/tex]
[tex]Each = \frac{15/4}{32}[/tex]
Rewrite as:
[tex]Each = \frac{15}{4*32}[/tex]
[tex]Each = \frac{15}{128}[/tex]

Given the inequality, select all the values of x that make that inequality true 3(2k-1)<9 0 1 2 3 4
Answers
Answer:
We have the inequality:
3*(2*x - 1) < 9
Where the given options are:
0, 1, 2, 3, 4
(you wrote k instead of x, but before you wrote "select all the values of x that make that inequality true", then I assume that the variable is x instead of k).
Again, let's start with the inequality:
3*(2*x - 1) < 9
and let's isolate the variable x.
(2*x - 1) < 9/3 = 3
(2*x - 1) < 3
2*x < 3 + 1 = 4
2*x < 4
x < 4/2
x < 2
Then all the values of x that are strictly smaller than 2 make the inequality true.
From the given options (0, 1, 2, 3, 4) the two that make the inequality true are:
x = 0
and
x = 1.

Answers
Answer:
65 seats
Step-by-step explanation:
1. Approach
To answer this question, one has to find the rate at which seats are added to each row. Then one must find the number of seats in the first row. Using this information, one can form an equation to find out how many seats are in any given row when given the row number. Finally, one can substitute (20) into the equation to find out how many seats are in the row (20).
2.Find the rate at which seats are added
One is given the row number and the corresponding number of seats in the row. This information is presented in the formate ([tex]x,y[/tex]), as the following is,
(3, 31), (6, 37)
Where (x) is the row number and (y) is the number of seats.
To find the rate at which seats are added, one must solve for the rate of change. This can be done using the following formula,
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute in the given information and solve for the rate of change,
[tex]\frac{37-31}{6-3}[/tex]
Simplify,
[tex]\frac{37-31}{6-3}\\=\frac{6}{3}\\=2[/tex]
Seats are added at a rate of (2) seats per row.
3. Find the equation
The easiest way to write the equation of this situation is to use the equation of a line is in the slope-intercept form. This form is as follows,
[tex]y=mx+b[/tex]
Where (m) is the slope of the line and (b) is the (y-intercept). As one found in (step (2)) the slope of the line is (2). Substitute this into the equation,
[tex]y=2x+b[/tex]
One is given that (3, 31) is a part of this scenario, substitute this point into the equation and solve for the unknown,
[tex](31)=2(3)+b[/tex]
Simplify,
[tex]31 = 6+b[/tex]
Inverse operations,
[tex]31=6+b\\25=b[/tex]
Substitute this into the equation to complete the equation,
[tex]y=2x+25[/tex]
4.Find how many seats are in the row (20)
Now that one has the equation to find the number of seats where (x) represents the row number and (y) represents the number of seats. Substitute in the row number (20) to solve to find the number of seats in the row.
[tex]y=2x+25[/tex]
[tex]y=2(20)+25[/tex]
Simplify,
[tex]y=2(20)+25\\y=40+25\\y=65[/tex]

Darcy harvests 8.3/4 acres of corn every 5/6 end fraction of an hour. Darcy harvests corn at a constant rate. How many acres does she harvest per hour?
Answers
Given:
Darcy harvests [tex]8\dfrac{3}{4}[/tex] acres of corn every [tex]\dfrac{5}{6}[/tex] of an hour.
Darcy harvests corn at a constant rate.
To find:
How many acres does she harvest per hour?
Solution:
We have,
Acres harvest in [tex]\dfrac{5}{6}[/tex] of an hours = [tex]8\dfrac{3}{4}[/tex]
Acres harvest in 1 hour = [tex]8\dfrac{3}{4}\times \dfrac{6}{5}[/tex]
= [tex]\dfrac{32+3}{4}\times \dfrac{6}{5}[/tex]
= [tex]\dfrac{35}{4}\times \dfrac{6}{5}[/tex]
Cancel out the common factors, we get
Acres harvest in 1 hour = [tex]\dfrac{7}{2}\times \dfrac{3}{1}[/tex]
= [tex]\dfrac{21}{2}[/tex]
= [tex]10\dfrac{1}{2}[/tex]
Therefore, she can harvest [tex]10\dfrac{1}{2}[/tex] acres of corn per hour.

You borrow $3,897 for a loan for college expenses with a 2.5% interest rate. How much interest is charged on the loan
Answers
Answer:
Amount of interest pay per year = $97.5 (Approx.)
Step-by-step explanation:
Given:
Amount borrow for college expenses = $3,897
Rate of interest = 2.5%
Find:
Amount of interest pay per year
Computation:
Using Simple interest formula;
Simple interest = Amount borrow x Rate of interest x number of year
Amount of interest pay per year = 3,897 x 2.5% x 1
Amount of interest pay per year = 3,897 x 0.025
Amount of interest pay per year = 97.425
Amount of interest pay per year = $97.5 (Approx.)

Answers
Answer:
x = 51, y = 17
Step-by-step explanation:
Consecutive angles sum to 180° , so
x + 129 = 180 ( subtract 129 from both sides )
x = 51
-------------------------------------
Opposite angles are congruent, so
3y = x = 51 ( divide both sides by 3 )
y = 17
Step-by-step explanation:
x + 129° = 180°
x = 180°- 129°
x = 51°
3y + 129° = 180°
3y = 180° - 129°
3y = 51°
y = 51°/3
y = 17°

How much of a radioactive kind of xenon will be left after 15 days if the half-life is 5 days and
you start with 96 grams
Answers
Answer:
12 grams
Step-by-step explanation:
15/5 = 3 half lives
(1/2)³ = 1/8 of the original amount will remain
96 * 1/8 = 12 grams
Answer:
Step-by-step explanation:
Radioactive decay problems are very similar to compound interest formulas, except the rate is subtracted from one, instead of adding to one.
I.e.
mass at time t, m(t) = M (1 - r)^(t/h)
where
M = initial mass (grams)
m (t) mass left at time t (grams)
h = half-life in number of days
r = 0.5 from "half-life"
t = time lapse in number of days
Here
M = 96
h = 5
t = 15
m(15) = 96(1-0.5)^(15/5)
= 96 (1/2)^3
= 12 grams
