Answer:
- 9
Step-by-step explanation:
Substitute x = - 3 into the expression
(- 3)² - 2(- 3) - 24
= 9 + 6 - 24
= 15 - 24
= - 9

Step-by-step explanation:
Which expression has a value that is less than the base of that expression? A. 2^3 B. (5/6)^2 C. 3^1 D. 4^4
Answer:
B. (5/6)^2
Step-by-step explanation:
A. 2^3
= 2 × 2 × 2
= 8
The base is 2
Therefore, the expression is greater than the base
B. (5/6)^2
= 5/6 × 5/6
= 5*5 / 6*6
= 25/36
Base = 5/6 = 0.833
Expression =25/36 = 0.694
Therefore, the expression is less than the base
C. 3^1
= 3
The base is 3
Therefore, the expression is equal to the base
D. 4^4
= 4 * 4 * 4 * 4
= 256
The base is 4
Therefore, the expression is greater than the base
The correct answer is B. (5/6)^2

If we look at basic translation rules we would know that when something moves to the left it becomes a +, we can also see that because the graph moved horizontally the answer must be in a parenthese.
Answer:
c
Step-by-step explanation:
b and d both have +3 in the equation, so no.
a only moves the equation down, when we're trying to move it to the left, so C would be the only one left.
Rey paid $91 for a watch that was on sale for 30% off. Grace and Curtis were debating how much the original price was. Grace said it would be $118.30 but Curtis said the original price should be $130.
Which person do you agree with? Why?
grace or curtis ?
Answer:
Grace is right
Step-by-step explanation:
91 x 0.30 = 27.3
91 plus 27.3 equals to 118.3
Answer:
Curtis - The original price is $130.
Step-by-step explanation:
30% off means Rey paid 70% of the original price.
0.70x=91
x=91/0.70
x=130

The area of a triangle is 169 square meters. The base of the triangle is twice the height. Find the base and height.
I would like the answer and how to get it (show work).
Thanks!
Answer:
The base of the triangle has a length of 26 meters, and the height of the triangle has a length of 13 meters.
Step-by-step explanation:
Equation to find the height: [tex]\frac{2x*x}{2} = 169[/tex] ⇒ [tex]x^2=169[/tex] ⇒ [tex]x=13[/tex] meters.
If the height of the parallelogram shown is increased by 1 cm and the base is increased by 2 cm, what is the area of the new parallelogram?
A parallelogram with a base of 9 centimeters and a height of 4 centimeters.
28 cm2
39 cm2
55 cm2
60 cm2
My main problem: The base isn't at the top, so therefore I am confused. It should be on top of the shape but it is not. If it was I could figure it out.
So sorry I messed it up I let you down :(
Answer:
55 cm²
Step-by-step explanation:
In a parallelogram, the top base is equal to the bottom base (and the sides are equal to each other too!)
So the top and bottom base are both 9, and the left and right sides are both 5.
So, to solve, we need to use the equation:
(4 + 1) * (9 + 2) = 5 * 11 = 55 cm²

Find the area of the triangle. Enter your answer in the box. An obtuse triangle. The base of the triangle is fourteen millimeters. The long side of the triangle is twenty-seven millimeters. The height of the triangle is twelve millimeters.
Answer: [tex]84\ mm^2[/tex]
Step-by-step explanation:
Given
The long side of a triangle is 27 mm
The length of the base is 14 mm
height of the triangle is 12 mm
The area of a triangle is given by
[tex]\Rightarrow \dfrac{1}{2}\times \text{base}\times \text{height}[/tex]
Insert the values
[tex]\Rightarrow \dfrac{1}{2}\times 14\times 12\\\\\Rightarrow 84\ mm^2[/tex]
Thus, the area of the triangle is [tex]84\ mm^2[/tex]

B
The tree is 3 feet tall.
C
The roots are 3 feet below the ground.
D
It was 3 degrees below zero.

Please help!! ASAP
the number 3.5 is...
============================================================
Explanation:
In your studies so far, every number you encounter is a real number. This changes when your teacher will introduce complex and imaginary numbers later on down the road. So 3.5 is a real number. A real number is essentially any number we can express as a decimal value (whether the decimal terminates, or goes on forever).
The number 3.5 is also rational because we can express it as a ratio of two integers, aka a fraction of two integers. Specifically, we can say 3.5 = 35/10 = 7/2.
The number 3.5 being rational would automatically rule out "irrational", since "irrational" means "not rational". The number 3.5 isn't an integer either. It would need to be either a positive whole number, negative whole number, or zero for it to be an integer. We rule out "natural number" for similar reasoning that we ruled out "integer".
Quantity demanded is 200 units when the unit price is set at $90. The quantity demanded is 1200 units when the unit price is $40. Find the demand equation
Answer:
[tex]Q_n=(2000)-(20)P_n[/tex]
Step-by-step explanation:
From the question we are told that:
Initial Quantity demanded Q_1= 200 units
Initial demand price [tex]P_1=\$90[/tex]
Final Quantity demanded [tex]Q_2= 1200 units[/tex]
Final demand price [tex]P_2=\$40[/tex]
Generally the Demand Equation is mathematically given by
[tex]Q_n=a-bP_n[/tex]
Where
a=Other factors affecting price
b=Slope of the demand curve
Therefore
[tex]Q_1=a-bP_1[/tex]
[tex]200=a-b(90)[/tex]
[tex]Q_2=a-bP_2[/tex]
[tex]1200=a-b(40)[/tex]
Comparing both above equations
[tex]a=2000[/tex]
[tex]b=20[/tex]
Therefore the Demand Equation is mathematically given by
[tex]Q_n=(2000)-(20)P_n[/tex]

Find x.
Round to the nearest tenth.
7cm 7cm 10cm x
x = [? ]cm
Answer:
4.9 cm
Step-by-step explanation:
To solve this problem you would use the power of a point formula where two chords intersect in the interior of a circle. We get the equation:
7 * 7 = 10 *x
49 = 10x
x = 4.9 cm
Answer:
x = 4
Step-by-step explanation:
the first line (7cm and 7 cm) are the diameter. You add both numbers to get the diameter which would be 14. Then then next line (10 cm and x) would be the diameter as well. You can create an equation for this (10 + x = 14).
Subtract 14-10 and you get 4. Therefore x = 4
Please help me work this out
Answer:
14400 boxes
Step-by-step explanation:
After looking at this question you would first see that it is looking for how many cuboids can fit into the container. That would mean that the final equation should be the volume of container divided by the volume of the cuboid.
First, we can find the volume of the container. Keep in mind that the volume of a rectangular prism is V=Bh (which means area of the base times the height)
For the base we would do (600)(200) which is 120000
Next, the height is 300, so we would times that by 120000 (which is 36000000)
Moving on to the cuboid!
We would do the same process, but with smaller units.
(same equation) V=Bh
B= (50)(20)
=100
(100)(25)=2500
Lastly, like mentioned in the beginning, take the volume of the container and divide by the volume of the cuboid.
36000000/2500=14400
Therefore, 14400 boxes can fit into this container!
Hope this helps! :)
Answer:
Step-by-step explanation:
so they made the boxes fit perfectly into the container.. as they are.
notice that each of the dimensions of the box fit perfectly into the dimensions of the container.
length container of 600 / length of box 50=12
width of container of 200 / width of box 20 = 10
height of container of 300 / heigth of box 25 = 12
now just multiply those 3 answers
12 * 10 * 12 = 1440 boxes :)
BTW ( by the way ) I can see by what you have erased you did do the
300 ÷25 =12 correctly , (300/25), and the
200÷20 = 10 correctly, (200/20) but the
600÷50 = 20 was not correct. You can check this in your head really quickly by just multiplying 50*20 = 1000 , now you know that's not right, so then do 50*10=500 , that's close, hun, now just add 2 more 50s for a total of 600 and 12 , 50s :) see??
In the figure, AB || DC and AD || BC. To prove that AB = CD, one must first show that
AABC-ACDA.
Which theorem or postulate can be used to justify AABC - ACDA?
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral, obtuse, acute and right angled triangles.
Two triangles are said to be congruent if all the corresponding sides and angles of both triangles are equal. Congruent triangles have the same size and shape.
Given that AB || DC and AD || BC, therefore:
∠DCA = ∠BAC (alternate angles are equal)
∠DAC = ∠BCA (alternate angles are equal)
AC ≈ AC
Therefore from triangle ABC and triangle CDA, since ∠DCA = ∠BAC, ∠DAC = ∠BCA and AC ≈ AC, hence both triangles are congruent by Ange-side-angle congruence theorem.
Therefore AB = CD
Answer:
the answer is AB is equal to CD
