A store is having a sale on jellybeans in trail mix. For 2 pounds of jellybeans and 12 pounds of trail mix, the total cost is $23. For 5 pounds of jellybeans and 3 pounds of trail mix, the total cost $17 find the cost for each pound of jellybeans in each pound of trail mix
Answer:
The jelly beans cost $2.25 / pound
The trail mix costs $1.25 / pound
Step-by-step explanation:
Let +a+ = cost/pound of jelly beans
Let +b+ = cost/pound of trail mix
(1) 6a + 2b =16
(2) 3a + 5b =13
Multiply both sides by 2
and subtract (1) from (2)
(2) 6a -2b = -16
(1) -6a -2b = -16
8b=10
b=1.25
and
(1) 6a+2b=16
(1) +3a+b=8
(1) 3a+1.25=8
(1) +3a=6.75
(1) a=2.25
if csc θ = -5/4 on the interval (270°, 360°), find tan θ.
Value of tan θ on the interval (270°, 360°) = -4/3
What is Pythagoras theorem?Pythagoras theorem states that in a right angled triangle, square of length of hypotenuse is equal to the sum of squares of lengths of other two sides, i.e. Perpendicular and base.
Given,
cosec θ = -5/4 on the interval (270°, 360°)
Given interval is on fourth quadrant.
Sine and cosecant are negative in fourth quadrant
cosec θ = -5/4
cosec θ = Hypotenuse/perpendicular
Comparing
Hypotenuse = 5
Perpendicular = 4
By Pythagoras theorem,
Base² = Hypotenuse² - Perpendicular²
Base² = (5)² - (4)²
Base² = 25 - 16
Base² = 9
Base = ±3
In fourth quadrant tangent is negative
tan θ = -4/3
Hence, -4/3 is the value of tan θ on the interval (270°, 360°).

If m angle RTS = 8x + 18, find x so that line TR is perpendicular to line TS
Answer:
Point T is the right angle of the triangle, so RTS = 90 degrees
8x + 18 = 90 (degrees)
8x = 72
x = 9 degrees
Step-by-step explanation:
If [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then [tex]x[/tex] will be [tex]9^0[/tex].
What is perpendicular ?A line is said to be perpendicular to another line if the two lines intersect at a right angle i.e. make [tex]90^0[/tex] angle with that line.
We have,
[tex]\triangle RTS[/tex] in which,
[tex]\angle RTS=8x+18[/tex]
Also it is mentioned that [tex]TR \perp TS[/tex] i.e.
[tex]\angle RTS=90^0[/tex]
So, compare values of [tex]\angle RTS[/tex],
We get,
[tex]8x+18=90[/tex]
[tex]8x=72[/tex]
[tex]x=9^0[/tex]
Hence, we can say that If [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then [tex]x[/tex] will be [tex]9^0[/tex].

Madge leaves her home at 8:05 to go to school. The drive takes hour each way. If she is at school for 7 hours, what time does she arrive home? Help fast please.
Answer:
5:05 pm
Step-by-step explanation:
According to the Question,
Given, Madge leaves her home at 8:05 am to go to school. The drive takes an hour each way. Thus, He Reached School at 8:05 am + 1 Hour(going to school) = 9:05am. Now, If he is at school for 7 hours, Thus The School is Over at 9:05 am + 7 hours = 4:05 pm.And, Time Taken by him to Arrive at home from school is 1 hour. Thus, the time does he arrive at home is 4:05 pm + 1 hour = 5:05 pm.A certain pet store sells only dogs and cats. In
March, the store sold twice as many dogs as cats.
In April, the store sold twice the number of dogs
that it sold in March, and three times the number
of cats that it sold in March. If the total number of
pets the store sold in March and April combined
was 500, how many dogs did the store sell in
March?
The number of cats and dogs will be 200 and 300, respectively.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A certain pet store sells only dogs and cats. In March, the store sold twice as many dogs as cats. In April, the store sold twice the number of dogs that it sold in March and three times the number of cats that it sold in March.
Let the number of cats sold in march be x and the number of dogs sold in march be y. Then the equations will be
y = 2x
Then the number of cats sold in April will be 3x and the number of dogs sold in April will be 2y.
If the total number of pets the store sold in March and April combined was 500. Then we have
x + y + 3x + 2y = 500
x + 2x + 3x + 4x = 500
10x = 500
x = 50
Then the value of y will be
y = 2 (50)
y = 100
Then the number of cats sold will be
⇒ 50 + 3 × 50
⇒ 50 + 150
⇒ 200 cats
Then the number of dogs will be
⇒ 100 + 2 × 100
⇒ 100 + 200
⇒ 300
Thus, the number of cats and dogs will be 200 and 300, respectively.

solve for x! show work please < 3
Answer:
x=10
Step-by-step explanation:
First off those are not triangles, tell someone that if you can and it hasn't been said already. Since 6 and 9 correspond we know the big triangle is 1.5 times the size of the small one. Because of this, we can set 1.5(2x-10) or 3x -15 = 15. x = 10. You can also just take 15/1.5 to get 10 but the stuff above is the work.
Answer:
x = 10
Step-by-step explanation:
since the two shapes are similar , setting them up in proportion can help to find x, like this ;
2x - 10 / 15 = 6 / 9......cross multiply
9 × ( 2x - 10 ) = 6 × 15
18x - 90 = 90
18x = 90 + 90
18x = 180
x = 10

Translate the sentence into an inequality.
Twice the difference of a number and 5 is at most 27.
Use the variable b for the unknown number.
Answer:
2b-10≤27
Step-by-step explanation:
In this problem, we use b to represent the unkown number. Please be careful of order of operations when writing the inequality. (The difference of a number and 5) multiplied by 2 is at most 27. Also, note that the both sides of the inequality can be 27, but no more than 27.
[tex]2(b-5)\leq 27\\2b-10\leq 27\\[/tex]
If you wish to solve for b from here, simply isolate the term containing b and solve from there.
I hope this helps! Let me know if you have any questions :)
Answer:
2(x - 5) < 27
Step-by-step explanation:
Equation
2(b - 5)<27
Explanation
Break this down
difference means subtract.
The number is b
and finally for now, the difference between a number and 5 is
x - 5
Twice that difference is
2(x - 5)
And the keyword less (than) 27. Always make sure you know what less than means. It means that it is never equal to 27, but it can be pretty close.
26.999999999999 < 27
So the final result is
2(x - 5) < 27
