In a half-kilo jar of legumes there are 2.5g of fat. In another 400g can of legumes B there is 2.1g of fat. Are these data in proportion? If the data is not in proportion, in which of the two cans is there more fat proportionally?
Answer:
no400 g canStep-by-step explanation:
A half-kilo jar is 500 grams, so a 400 g can would be 4/5 the weight. 4/5 of 2.5 g of fat would be 2.0 g of fat. The 400 g can has 2.1 g, so has more fat, proportionally, than its weight would suggest.
The fat is not proportional to the can sized. The 400 g can has more fat, proportionally.

Answer:
I think the answer is C. 324 but i'm not sure. lemme know if i'm wrong and what the correct answer is
Step-by-step explanation:
The area of the given Circle C is; 324π
What is the area of the circle?
From the attached diagram, we see that;
WX is the radius of circle X and is equal to 8 units
Similarly, ZY is radius of circle Y and is equal to 10 units.
Thus, diameter of circle X = 8 * 2 = 16 units
Diameter of circle Y = 10 * 2 = 20 units
Thus;
Diameter of circle C = 20 + 16 = 36 units
Area of Circle C = π * 36²/4
Area of Circle C = 324π

Answer:
x = 50
Step-by-step explanation:
You are correct.
x + m<PQS + m<PSQ = 180
m<PQS = m<QRT = 70
m<QST + m<PSQ = 180
120 + m<PSQ = 180
m<PSQ = 60
x + 70 + 60 = 180
x + 130 = 180
x = 50

Step-by-step explanation:
If the point (a,3) lies on the graph of the equation 5x+y=8, then a=
Answer:
a = 1
Step-by-step explanation:
The given equation is:
=> 5x+y = 8
Also,
Point = (x,y) = (a,3)
So, x = a , y = 3
Putting this in the above equation
=> 5(a)+3 = 8
=> 5a = 8-3
=> 5a = 5
Dividing both sides by 5
=> a = 1

Answer:
x = 3/2 x = -5/2
Step-by-step explanation:
(2x+3) ^2 - 4(2x+3) - 12 = 0
Let m = 2x+3
m^2 - 4m - 12 = 0
Factor
(m-6) (m+2) = 0
Using the zero product property
m-6 = 0 m+2 =0
m = 6 m = -2
Substitute m = 2x+3 back into the equation
2x+3 = 6 2x+3 = -2
2x = 3 2x = -5
x = 3/2 x = -5/2

How many diagonals can be drawn from each vertex of a 15-gon?
11
18
12
8
None of these answers are correct.
Answer:
Correct option: third one -> 12
Step-by-step explanation:
In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.
If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.
Correct option: third one
Complete the factorization of 3x ^ 2 - 10x + 8 3x^ 2 -10x+8=(x- Box x-4)
Answer:
[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]
Step-by-step explanation:
The general form of a quadratic polynomial is given by:
[tex]ax^2+bx+c[/tex] (1)
You have the following polynomial:
[tex]3x^2-10x+8[/tex] (2)
In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:
[tex]x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex] (3)
By comparing the equation (1) with the equation (2) you obtain:
a = 3
b = -10
c = 8
Then, you replace these values in the equation (3):
[tex]x_{1,2}=\frac{-(-10)\pm \sqrt{(-10)^2-4(3)(8)}}{2(3)}\\\\x_{1,2}=\frac{10\pm2}{6}\\\\x_1=2\\\\x_2=\frac{4}{3}[/tex]
Then, the factorization of the polynomial is:
[tex]3x^2-10x+8=(x-x_1)(x-x_2)=(x-2)(x-\frac{4}{3})[/tex]

Substitute with One Solution
2x -y=-11
6x + y = 3
Answer:
x=1, y = -3
Step-by-step explanation:
2x -y=-11
6x + y = 3
Add the two equations together
2x -y=-11
6x + y = 3
--------------------
8x = 8
Divide by 8
8x/8 = 8/8
x= 1
Now find y
6x+y = 3
6(1) +y = 3
6+y =3
Subtract 6 from each side
6+y-6 = 3-6
y = -3
Suppose students are independent from one another. 63% of students are using Mr. Martin's new social media app, Mar-tin-stagram. 2 students are randomly selected. What is the probability that both of them use it?

Probability that both of them use it = 0.3945
Step-by-step explanation:
Given:
Student use app = 63%
Number of chosen student = 2
Computation:
Assume total number of student = 100%
So, probability that both of them use it.
⁶³C₂ / ¹⁰⁰C₂

Answer: 35 / 66
Step-by-step explanation:
Given the data bekow:
Outcome : - - - 1 - - - 2 - - - 3 - - - 4 - - - 5 - - - 6
Frequency : - 12 - - - 9 - - - 11 - - 8 - - - 12 - - - 14
What is the experimental probability of spinning an odd
P(spinning an odd) = (number of occurrence of an event / number of trials)
Odd outcomes = 1, 3, 5
Frequency of 1 = 12
Frequency of 3 = 11
Frequency of 5 = 12
Number of occurrences of odd = (12 + 11 + 12) = 35
Number of trials = 66
Therefore,
P(spinning an odd) = 35 / 66

Answer:
3pi/4 =x and 5pi/4 =x
Step-by-step explanation:
cos x + sqrt(2) = - cos x
subtract cos x from each side
cos x - cosx + sqrt(2) = - cos x - cos x
sqrt(2) = -2 cos x
Divide each side by -2
-sqrt(2) / 2 =-2 cos (x) /-2
-sqrt(2) /2 =cos (x)
Take the inverse cos of each side
cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))
3pi/4 =x and 5pi/4 =x
Answer:
Here's your answer:
3pi/4 =x and 5pi/4 =x
cos x + sqrt(2) = - cos x
subtract cos x from each side
cos x - cosx + sqrt(2) = - cos x - cos x
sqrt(2) = -2 cos x
Divide each side by -2
-sqrt(2) / 2 =-2 cos (x) /-2
-sqrt(2) /2 =cos (x)
Take the inverse cos of each side
cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))
3pi/4 =x and 5pi/4 =x

If £31 = 500 rubles, how many £ are in 992 rubles? Give your answer to 2 dp.
Answer:
There are £61.50 in 992 rubles
Step-by-step explanation:
Here, we shall be doing some currency conversions.
Now,
£31 = 500 rubles
Then;
£x = 992 rubles
To get c, what we do is simply cross multiply
£x * 500 rubles = £31 * 992 rubles
£x = (£31 * 992 rubles)/500 rubles
£x = £61.504
which is £61.50 to two decimal places

Franco made a dozen muffins for his party. Upon taking them out of the oven,
he noticed that 2 of the muffins were badly burned. Franco served of the remaining muffins.
10
Which equation shows the fraction of the non-burned muffins that remains?
Answer:
Option B.
Step-by-step explanation:
This question is incomplete; find the complete question with the attachment.
Franco made number of muffins = a dozen
A dozen muffins = 12 muffins
Number of muffins were burned = 2
Remaining muffins = 12 - 2 = 10
Franco served 7 of the remaining non-burned muffins,
Fraction of muffins served = [tex]\frac{7}{10}[/tex]
Remaining muffins = 3
Fraction of remaining muffins = [tex]\frac{3}{10}[/tex]
Fraction of remaining non-burned muffins we can get from,
[tex]\frac{10}{10}-\frac{7}{10}=\frac{3}{10}[/tex]
Option B is the correct equation.
