Answer:
1.62 pounds
Step-by-step explanation:
Let x be the pounds of Arabica
Take the number of pounds times the cost of each of the coffees individually
This must be equal to the number of pounds times the cost together
x * 28 + 8.75 *3 = ( x+3) 15.50
28x+26.25=(x+3)15.50
Distribute
28x+ 26.25 = 15.50x + 46.50
Subtract 15.50x from each side
28x-15.50x +26.25 = 15.50x +46.50-15.50x
12.50x + 26.25 = 46.50
Subtract 26.25 from each side
12.50x +26.25-26.25 = 46.50-26.25
12.50x = 20.25
Divide each side by 12.5
12.5x/12.5 = 20.25/12.5
x =1.62
Answer:
I think its 1.62 pounds

Explanation: If something (a number or pattern) in a decimal is repeating, then you can put it in fraction form like this. the pattern is 8 .
Hope this helps!-xoxo
Answer:
[tex]\frac{8}{9}[/tex]
Step-by-step explanation:
We have to create 2 fractions with the repeating number placed after the decimal point.
let x = 0.88.... → (1) ( multiply both sides by 10 )
10x = 8.88.... → (2)
Subtract (1) from (2), eliminating the repeating decimal
9x = 8 ( divide both sides by 9 )
x = [tex]\frac{8}{9}[/tex]
Thus 0.888..... = [tex]\frac{8}{9}[/tex]

Select all the true statements given the figure.
A. m∠4 = m∠2
B. m∠4 = m∠1 + m∠2
C. m∠4 = 180 − m∠3
D. m∠4 = m∠1 + m∠2 + m∠3
E. m∠4 = m∠3 + m∠1
The true statement about the given triangle figure is B and C.
What are the properties outer angle of a triangle?The triangle has the following characteristics: All triangles, regardless of kind, have an angle total of 180 degrees. The length of a triangle's two longest sides added together is longer than the third side. Similarly to this, the length of the third side of a triangle third side is shorter than the difference between its two sides.
Given a triangle, where m∠4 is an outer angle. from the properties of the outer angle of the triangle, Each Exterior angle = 180° - Interior angle. This formula can be used if the corresponding interior angle is given. Exterior angle = Sum of Interior opposite angles. The sum of all the exterior angles of a triangle is 360°.
Therefore, only option B and C which is m∠4 = m∠1 + m∠2 and m∠4 = 180 − m∠3 respectively are true statements about the given triangle.

I if the no of Girates at congtin were reduced by 63% what would be the approximate ratio of giraffes to animals in other category be?
Answer:
[tex]Giraffe:Others = 3:7[/tex]
Step-by-step explanation:
See Attachment for complete question
For this question, we only need the data at the Congtin column.
So, we have:
[tex]Giraffes = 124[/tex]
[tex]Other = 108[/tex]
First, we need to reduce Giraffe by 63%.
This gives:
[tex]New\ Giraffe = Giraffe - 63\% * Giraffe[/tex]
[tex]New\ Giraffe = 124 - 63\% * 124[/tex]
[tex]New\ Giraffe = 124 - 78.12[/tex]
[tex]New\ Giraffe = 45.88[/tex]
Represent this as a ratio:
[tex]Giraffe:Others = 45.88:108[/tex]
The closest to this ratio is 3:7.
This is shown by dividing the ratio by 15
i.e.
[tex]Giraffe:Others = 45.88/15:108/15[/tex]
[tex]Giraffe:Others = 3.0589:7.2[/tex]
Approximate:
[tex]Giraffe:Others = 3:7[/tex]

A line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5. What is the value of n?
(4,6),(5,3),(7,2),(9,3)
The value of n is 4 if the line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
A line passes through points A(n,4) and B(6,8) and is parallel to y=2x-5.
The slope of the line which passes through points A(n,4) and B(6,8)
[tex]\rm m =\dfrac{8-4}{6-n}[/tex]
m = 4/(6 - n)
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The slope of the line y = 2x - 5
M = 2
The lines are parallel which means the slope of the lines will be equal
m = M
4/(6 - n) = 2
2 = 6 - n
n = 4
Thus, the value of n is 4 if the line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5.

The perimeter of an isosceles triangle is 21 cm. The length of each equal side is triple
the length of the base. Find the side lengths of the triangle.
Let the length of the base of this isosceles triangle be = x
One of its equal sides = 3x
Another one of its equal sides = 3x
Their perimeter = x + 3x + 3x = 21 cm
To find the value of each side let us first solve this equation .
= x + 3x + 3x = 21 cm
= 7x = 21 cm
= x = 21 ÷ 7 ( transposing ×7 from LHS to RHS changes ×7 to ÷7 )
= x = 3
Then length of base = 3 cm
Length of one equal side = 3 × 3 = 9 cm
Length of another equal side = 3 × 3 = 9 cm
Therefore , the the three sides of this triangle = 3 cm , 9 cm and 9cm .

It costs $60 to join the Alpha Fitness Club, plus an additional $5 per month. It costs $20 to join the Omega Fitness Club, plus an additional $10 per month. After how many months of membership would it cost the same to belong to either fitness club? What is that cost?
10a) After _____ months,
10b) the cost to belong to either fitness club would be __________.
Well, we know that it costs $60 plus 5 per month for Alpha Fitness Club.
We also know that it costs $20 plus 10 per month for Omega Fitness Club.
In order to find out which one would cost the most, we must add the additional costs to the original join cost.
(NEVER add the join cost, just do the join cost at the beginning or else the clubs will never become the same cost.)
Club M1 M2 M3 M4 M5 M6 M7 M8 M9
Alpha: 60 65 70 75 80 85 90 95 100
Omega:20 30 40 50 60 70 80 90 100
If you look above, you realize that there is a time when they both cost the same.
Summary sentence:
After 9 months, the cost to belong to either fitness club would be $100.

Pavan is on his high school bowling team and scores an average number of 135 pins per game. During the course of a match, he bowls 146 in the first game and 135 in the second game. In his third game, he bowled 8 less pins than in his forth game.
a.) Let p be the score Pavan scored in his forth game. Set up an equation that models this equation.
b.) What were Pavan's score in the third and forth game?
9514 1404 393, H76, 5668 8637 469
Answer:
a) (146 +135 +(p-8) +p)/4 = 135
b) 3rd game: 125.5; 4th game: 133.5
Step-by-step explanation:
The average score is the sum of scores divided by the number of games.
We are told the 4th game score is p, and the third game score is p-8. So, the scores in the four games are ...
146, 135, p-8, p
__
a) Their average is 135, so we have ...
(146 +135 +(p-8) +p)/4 = 135 . . game average
__
b) Solving the equation, we get ...
273 +2p = 540 . . . . . . . . . . . . . multiply by 4, collect terms
2p = 267 . . . . . . . . . . . . . . . . . . subtract 273
p = 133.5 . . . . . . divide by 2
Then the third game score is p-8 = 133.5-8 = 125.5, and the fourth game score is 133.5
Pavan's scores in the 3rd and 4th games were 125.5 and 133.5, respectively.
