How many tons are equal to 36,000 pounds?
Question 5 options:
1,800 tons
180 tons
18 tons
8 tons
Answer:
[tex]\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: Solution :- \: 18 \: tons}}}}}}}}[/tex]
Step-by-step explanation:
We know that,
1 pound = 0.0005 ton.To convert pound to tons, we need to divide the value of the mass by 2000. So,
36,000 pounds in tons = 36,000/2000= 18 tons (3rd option)________

Ashanti averaged 9 points per game. Write the two rates (ratios) implied by this statement. How many point
would she score if she played 14 games and maintained this average?
Answer:
Step-by-step explanation:
I can't think of many ratios, but here are two:
Ashanti sored:
(9 points)/(1 game), and
(1 game)/(9 points)
If she maintains an average of (9 points)/(1 game), after 14 games we would predict:
(9 points)/(1 game)*(14 games) = 126 points total

What is the value of x, y, and z?
Answer: x = 34º, y = 146º, z = 146º
Step-by-step explanation:
Adding the angles inside a triangle gives you 180º. So
85 + 61 + x = 180
146 + x = 180
x = 34º
x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.
y and z are equal (vertical angles), so z = 146º.

Answer choices:
30 degrees
124 degrees
94 degrees
35 degrees
Answer:
A. 94 degrees
Step-by-step explanation:
Both the angles are similar and can be called parallel angles.
They are equal to each other so:
m∠2 = m∠3
4x - 26 = 3x + 4
4x - 3x = 4 + 26
x = 30°
m∠2 = 4x - 26
= 4(30) - 26
= 94°
Answer:
∠ 2 = 94°
Step-by-step explanation:
∠ 2 and ∠ 3 are vertically opposite angles and are congruent, so
4x - 26 = 3x + 4 ( subtract 3x from both sides )
x - 26 = 4 ( add 26 to both sides )
x = 30
Then
∠ 2 = 4x - 26 = 4(30) - 26 = 120 - 26 = 94°

Is it a better buy to get the 10-ounce box for $1.86 or the 14-ounce box for $2.61?
It really depends on what you need. In terms of cents per ounce, the 14-ounce box is the cheaper option per ounce. However if you only need a little, it does not make sense to pay more just for the sake of sale. Just buy the 10 ounce box. However if you need bulk, it makes more sense to buy the 14 ounce boxes because, in the end, it will end up being cheaper.
I hope this helps and it wasnt confusing
Answer:
$1.86 for 10 oz is a better buy by a very small amount.
Step-by-step explanation:
To answer the question, we find the unit rates of both boxes.
$1.86 for 10 oz:
unit rate = $1.86 / 10 oz = $0.186/oz
$2.61 for 14 oz:
unit rate = $2.61 / 14 oz = $0.18642857142.../oz
$1.86 for 10 oz is a better buy by a very small amount.
What is the inverse of this function
Answer:
D
Step-by-step explanation:
How to find the inverse of a function.
- Replace f(x) with y
- Swap x and y places. (sign doesn't matter here.)
- solve for y.
f(x) = 8√x
y = 8√x
x = 8√y
x^2 = (8√y)^2
x^2 = 64y
y = x^2 / 64
= (1/64) x^2

a humer four-door costs the dealer $57,915 the deaer has a 12.3% makeup
Answer:
65038.55
Step-by-step explanation:
First, Let's turn 12.3% into a decimal which is 0.123
Then Multiply 57,915 by 0.123
57,915 × 0.123= 7123.545 Round; 7,123.55
Then Add [Mark up = Add] 57,915 with 7,123.55
57,915 + 7,123.55= 65038.55
Hence, the Answer is 65038.55

What is the value of S in the equation?
24 - S = 6 x 3
42
15
6
9
Answer:
6
Step-by-step explanation:
to answer this we do the following:
24 - s = 6 x 3 (which is 18)
24 - s = 18
now the equation literally says '24- s has to equal 18'
so we work out s by: 24-18= 6
so s has to equal 6

If f(x) = startfraction 7 over x endfraction, then what is the slope of f(x) at x = 5? round your answer to 3 decimal places.
The slope of the function to 3 dp is 0.280
Slope of a functionSlope is also known as the gradient of a function
Given the function [tex]f(x) =\frac{7}{x}[/tex]
Taking the derivative of the function will give:
[tex]f'(x)=-\frac{7}{x^2}[/tex]
Substitute x = 5 into the equation to have:
[tex]f'(x)=-\frac{7}{5^2}[/tex]
[tex]f'(x) = -\frac{7}{25}[/tex]
Hence the slope of the function to 3 dp is 0.280

8x -(-5) = 29 To make the equation true, what is the value of x?
Answer:
3
Step-by-step explanation:
Because you just have to replace and what would it give = 8(3) -(-5) = 29
Answer:
x = 3
Step-by-step explanation:
In order to solve this equation, first we need to make the equation easier to read.
So instead of:
8x - (-5) = 29
We will do:
8x + 5 = 29
(Note that we have a plus sign now, because subtracting a negative number is the same as adding a positive number.)
Next we move the 5 to the other side of the equal sign, by subtracting it.
Now we have:
8x = 24
Finally we isolate the x variable, by dividing by 8 on both sides.
(24 ÷ 8 = 3)
Our answer is 3, therefore x = 3.

Find the x- and y-intercepts of the graph of 10x+2y=20 State each answer as an integer or an improper fraction in simplest form.
Answer:
Slope: [tex]\frac{10.000}{2.000} = -5.000[/tex]x - intercept: [tex]\frac{10}{5} = 2[/tex].y intercept: [tex]\frac{10}{1} = 10.00000[/tex].Step-by-step explanation:
Simplify:
Simplify the equation by subtracting what is to the right of the equal sign from both sides of the equation:10*x+2*y-(20)=0.Step 1:
Pull out like factors:10x + 2y - 20 = 2 * (5x + y - 10)Step 2:
Equations which are never true:Solve:2 = 0This can't be solved.A non-zero constant never equals 0.Equation of a straight line:Solve: 5x+y-10 = 0"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.In this formula:y tells us how far up the line goesx tells us how far alongm is the Slope or Gradient i.e. how steep the line isb is the Y-intercept i.e. where the line crosses the Y axisThe X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5x+y-10 = 0 and calculate its propertiesCalculate the y-intercept:Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000 y-intercept = 10/1 = 10.00000 Calculate the x-intercept:Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is -0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -0.000 - 10.000 = -10.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN) Slope = -10.000/2.000 = -5.000Answers:
Slope = -10.000/2.000 = -5.000 x-intercept = 10/5 = 2 y-intercept = 10/1 = 10.000006th grade mathematics

Which equation shows the vertex form of a quadratic equation with vertex (2, 5)?
A: f(x) = a(x – 2)^2 + 5
B: f(x) = a(x + 2) ^2+ 5
C: f(x) = a(x – 2)^2 – 5
D: f(x) = a(x + 2) ^2– 5
Answer:
Option A f(x) = a(x - 2)^2 + 5
Step-by-step explanation:
Vertex Form : y = a(x-h)^2 + k
In this case, we don't need the a-term because we are only looking for the vertex.
The h-term is how this parabola moved horizontally.
Since the x value is 2, that means that the graph moved 2 spaces towards the right. We plug it in to get:
y = (x - 2)^2
Now we need to find the k value. We see that the vertex is (2,5), and the y-value is 5. That means that the graph moved up to 5 units. Now we plug 5 into the k-value, and this is what we get:
y = (x - 2)^2 + 5
Walah! We're done with the equation, and as we can see, the answer is option A!

OX > 2
Hey there mate :)
As per question,
[tex]10x + 18 < - 2 \\ = > 10x < - 2 - 18 \\ = > 10x < - (2 + 18) \\ = > 10x < - 20 \\ = > x < - \frac{20}{10} \\ = > x < - 2[/tex]
Therefore, the option X < -2 is correct.
