how much food can this container hold if its 3 on the top and 9 on the side
Please help What is the distance between points (5, 2) and(-3,-4) on the coordinate
plane? *
Answer:
10 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (5, 2) and (x₂, y₂ ) = (- 3, - 4)
d = [tex]\sqrt{(-3-5)^2+(-4-2)^2}[/tex]
= [tex]\sqrt{(-8)^2+(-6)^2}[/tex]
= [tex]\sqrt{64+36}[/tex]
= [tex]\sqrt{100}[/tex]
= 10

Answer:
x = 25
Step-by-step explanation:
If JK and MN are parallel lines, then ∠JKL = ∠LMN = 61°
By the opposite angle rule, ∠JLK = 39°
In a triangle three angles sum up to 180°
so, ∠JLK + ∠JKL +LJK = 180°
39° + 61° + 3x+ 5 = 180°
3x = 75
x = 25
Step-by-step explanation:
[tex]61 + 39 + 3x + 5 = 180 \\ \\ 105 + 3x = 180 \\ \\ 3x = 180 - 105 \\ \\ 3x = 75 \\ \\ x = 75 \div 3 \\ \\ x = 25 \\ [/tex]
An easel with sides of equal length opened and placed on a desk. What type of triangle is formed by the easel and the desk by sides and by angles?
Answer:

Step-by-step explanation:
In this question it is given that the two sides of easel are same.
A triangle formed has three sides - two of easel and one of the table itself.
The angle formed in 90 degrees (right angle)
Hence the triangle is a isosceles right triangle

Liam had 75% more magnets than John at first. Liam gave away 200% as many magnets as John. John was left with 25% of the magnets he had at first. What fraction of Liam's magnets did he have in the end?
Answer: 6/4x
Then John ended up with v/4 magnets and gave away (3/4)x
Liam gave away 2 ( 3/4)x = 6/4x magnets and was left with x/4 magnets
Notice that they have the same number now so John has 100% of Liam's magnets

- neither law can be used
- law of sines
- law of cosines
- both laws can be used
Answer:
Law of sines
Step-by-step explanation:
i took the test
The law of sines can be used to calculate the side h. Hence, option B is correct.
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.
Hence, Hence, option B is correct.

Taylor bought some jeans on sale. The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans. Find the amount of money Taylor spent,
Answer:
30
Step-by-step explanation:
Let the amount of money Taylor spent = x
The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans.
Hence
1/5 × x = 6 jeans
x/5 = 6 jeans
Cross Multiply
x = 5 × 6 jeans
x = 30
The amount of money Taylor spent = 30

Stephen spent $12.35 at a food truck. He bought 3 burgers for $1.25 each and 4 corndogs.
How much did Stephen pay for each corndog?
$2.86
$8.60
$2.77
$2.15
Answer:
The 3rd one 2.15
Step-by-step explanation:
12.35 in whole
1.25 x 3 = 3.75
12.35-3.75= 8.60
[tex]\sqrt[4]{8.60}[/tex] = 2.15
pls give brainlist <33
Answer:
$2.15
Step-by-step explanation:
Start off by multiplying $1.25 by 3 to find out how much the burgers are all together. This would be $3.75 for all three of the burgers. Then subtract $3.75 from the total amount spent ($12.35). This would give you $8.60. To find how much he spend on each corndog, you do $8.60 divided by 4. This would give you the answer of $2.15.

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?
(x – 9)2 + (y + 4)2 = 25
(x + 4)2 + (y – 9)2 = 25
(x – 9)2 + (y + 4)2 = 100
(x + 4)2 + (y – 9)2 = 100
Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
Data
h = -4k = 9r = diameter/2 = 10/2 = 5Equation of CircleThe equation of circle is given by
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our values and get our equation
[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]
we substituted the values of h and k and made sure it's in the standard form of equation of a circle.
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
This looks exactly like
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

After how many years since leaving the band can Jake expect to have 1,000 members left in his fan club? Input your answer to the nearest tenth of a year. Then click done.
Answer:
9.4 years
Step-by-step explanation:
It is given that Jake left the band.
We are required to find after how many years the band would have 1000 members left since Jake left the band.
The graph is provided where the x-axis represents the number of years since Jake left the band and y-axis which shows the number of fan club members.
It also represents the equation which is [tex]$y=-2,129.75x+21,028.35$[/tex]
According to the question, when we substitute y i.e. number of members in the fan clubs as 1000 in the above equation ,we get :
[tex]$y=-2,129.75x+21,028.35$[/tex]
⇒ [tex]$1000=-2,129.75x+21,028.35$[/tex]
⇒ [tex]$-21,028.35+1000=-2,129.75x$[/tex]
⇒ [tex]$-20,028.35=-2,129.75x$[/tex]
⇒ [tex]$x=\frac{-20,028.35}{-2,129.75}$[/tex]
[tex]$x=9.40$[/tex]
