Answer: 9n-18
Step-by-step explanation:
1. We distribute the 9 to the n and -2
2. 9n-2(9)
3.9n-18 is our answer.
Answer: 9n-18 would be equivalent to to 9(n-2)
Step-by-step explanation: First multiply 9 times n. Then multiply 9 and 2 and you get -18.
In the standard (x,y) coordinate plane a right triangle has vertices at (-3,4)(3,4)(3,-4) what is the length in coordinates units of the hypotenuse of this triangle
Given:
The vertices of a right triangle are:
[tex](-3,4),(3,4),(3,-4)[/tex]
To find:
The length of the hypotenuse of the given right triangle.
Solution:
Let the vertices of the right triangle are [tex]A(-3,4),B(3,4),C(3,-4)[/tex].
The distance formula is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, we get
[tex]AB=\sqrt{(3-(-3))^2+(4-4)^2}[/tex]
[tex]AB=\sqrt{(3+3)^2+(0)^2}[/tex]
[tex]AB=\sqrt{(6)^2+0}[/tex]
[tex]AB=\sqrt{36}[/tex]
[tex]AB=6[/tex]
Similarly,
[tex]BC=\sqrt{(3-3)^2+(-4-4)^2}[/tex]
[tex]BC=\sqrt{(0)^2+(-8)^2}[/tex]
[tex]BC=\sqrt{64}[/tex]
[tex]BC=8[/tex]
And,
[tex]AC=\sqrt{(3-(-3))^2+(-4-4)^2}[/tex]
[tex]AC=\sqrt{(6)^2+(-8)^2}[/tex]
[tex]AC=\sqrt{36+64}[/tex]
[tex]AC=\sqrt{100}[/tex]
[tex]AC=10[/tex]
Now, taking sum of squares of two smaller sides, we get
[tex]AB^2+BC^2=6^2+8^2[/tex]
[tex]AB^2+BC^2=36+64[/tex]
[tex]AB^2+BC^2=100[/tex]
[tex]AB^2+BC^2=AC^2[/tex]
By the definition of the Pythagoras theorem, AC is the hypotenuse of the given triangle.
Therefore, the length of the hypotenuse is 10 units.

Answer: It will be set: a), e), g)
Step-by-step explanation:
In order to form a triangle then the sum of its angles has to be equal to 180 degrees. In order to find out if it’s possible to form a triangle from a specific set of angles, then you have to add them up and see if they are equal to 180 degrees. If they are then it’s a triangle if they less than or greater than 180 then a triangle cannot he formed.
Ariane feeds her kitten kkk grams of food 222 times in the morning and 222 times in the evening. She feeds her dog ddd grams of food 111 time in the morning and 111 time in the evening.
Which expressions can we use to describe how many grams of food Ariane feeds her animals per day?
Choose 2 answers:
Answer:
The required expression is,
4k + 2d
Step-by-step explanation:
Given,
She feeds her kitten k gram of food,
She feeds 2 times in the morning,
⇒ Food fed in morning = 2k,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = 2k,
So, the total food she gives to her kitten = 2k + 2k = 4k,
Now, She feeds her dog d gram of food,
She feeds 1 times in the morning,
⇒ Food fed in morning = d,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = d,
So, the total food she gives to her dog = d + d = 2d,
Hence, the total food she feeds to her animal in a day = 4 k + 2 d

340 you were right
Step-by-step explanation:
Answer:
340
Step-by-step explanation:
first you have to find one side
i will go with 10 and 8
10*8=80
there are two of them
160 save this number in your bank
8*5=40 for the base
there are two of these too
80 save this number in your mental bank
for the last side 10 and 5
10*5=50 there are two of them
100
now add them all up
100+80+160=340
hope this helps!
Identify the slope and y-intercept of the following equation:
3x - 2y = -10
Answer:
m=3/2,y-int=5
Step-by-step explanation:
y=mx+b is the slope equation. since -10 is at the end of the equation and it does not have a variable next to it yk it is the y-intercept. if you want you draw this on a graph and you can see that you go up 3 and over 2

T-shirt Sale
Any 3 T-shirts for $14.50
$3.99
$6.99
$5.99
A) Tom bought these three T-shirts at the sale price of $14.50. How much money did he save compared
to the original total price of the T-shirts?
Answer:
add 3.99 + 6.99 + 5.99 = 16.97 divide 14.50 by 16.97 you will get .854 multiply by 100 it is %85.4 that is the percentage he paid then he saves 100 - 85.4 = %14.6
A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2.
Answer:
16√3 cm³
Step-by-step explanation:
The volume of a triangular prism is given as:
V = (1/3)B*h
Where B is the area of the base and h is the height of the prism.
Given that B = 12√3. The height fro the diagram is BC.
Since ∠BAC = 30° and ∠BCA = 90°, we can find BC using trigonometric identity.
tan(30) = BC / AC
but AC = 4√3, hence:
tan(30) = BC / (4√3)
BC = 4√3(tan 30)
BC = 4
V = (1/3)B*h = (1/3)B* BC = (1/3) * 12√3 * 4 = 16√3 cm³
Answer:
its b

Tom spent half of his allowance going to the movies. He washed the family car and earned 7 dollars. What is his weekly allowance if he ended with 15 dollars?
Answer:
Tom's weekly allowance is $16.
Step-by-step explanation:
With the information provided, first you have to subtract the amount he earned washing the family car from the total amount he had to determine the amount he had left from his allowance after going to the movies:
$15-$7=$8
Now, since the statement indicates that tom spent half of his allowance going to the movies, this means that the $8 represents the amount left after going to the movies and it is half of his allowance. So, you have to multiply this amount by 2 to find his weekly allowance:
$8*2=$16
According to this,the answer is that Tom's weekly allowance is $16.

01/25
1/30
O 1/18
O 3/4
Plz help me
Answer:
1/25
Step-by-step explanation:
You have to add all of the supplies.
5 pencils + 6 pens + 3 glue sticks + 1 marker = 15 supplies
Put 3 over 15, since fractions are part over whole.
Now you have to simplify 3/15, which is 1/5.
Then you multiply 1/5 by 1/5 since he is trying twice, and this will give you 1/25.
find geometric probability
Answer: 67%
Step-by-step explanation:
Since we're not solving for area I would just divide this circle into 6 equal parts. 3 on both sides of the diameter. The orange parts take up about 120/180 on one sides of the circle. So 2/3 of half the circle are covered in orange which means 2/6 of the whole circle is covered in orange. Which leaves us with 4/6 blank or white area. 4/6 as a decimal is 0.6666667 or 67%
Answer:
66.67 % (Rounded to the nearest hundreth)
66.666..% or 66 2/3 %
Step-by-step explanation:
The area of the whole circle with radius 4 is 50.27
The white area is 4/6 = 2/3 of the total area = 33.51333333
The geometric probability is the favorable area divided by the total area
33. 513333 / 50.27 = 0.6666666 = 66.666666%
