The answer is 30
Step-by-step explanation:
Suppose the price per pack of tea is x and the price of coffee per pack is y
Then

If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.
Answer:
The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!
A store manager combines 2 lb of trail mix that contains some cashew nuts with 30 lb
of trail mix that is 20% cashews. The result is a trail mix that is 25% cashews. What is the concentration of cashews in the first mixture?
Answer:
100%
Step-by-step explanation:
Let p = percent of cashews in first mix
2p = lb. of cashews in first mix
30(.20) = 6 = lb. of cashews in second mix
32(.25) = 8 = lb. of cashews in the combined mix
So,
lb. of cashews in first mix + lb. of cashews in second mix = lb. of cashews in the combined mix
2p + 6 = 8
2p = 2
p = 1 = 100%
Answer:
100%

Event X: The letter selected comes before "E".
Event Y: The letter selected is found in the word "FACE".
Give the outcomes for each of the following events.
If there is more than one element in the set, separate them with commas.
Answer:
Step-by-step explanation:
U= {A,B,C,D,E,F,G}
X = {A, B, C, D}
Y = {A, C, E, F}
a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}
B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}
c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}
Element in the given sets will be [tex]\left \{ A,B,C,D \right \}[/tex] and [tex]\left \{ A,C,E,F \right \}[/tex]
Given information,
A tile is selected from seven tiles, each labeled with a different letter from the first seven letters of the alphabet.
X: The letter selected comes before "E".
Y: The letter selected is found in the word "FACE".
The outcomes in favour of X will be:
[tex]X=[/tex] [tex]\left \{ A,B,C,D \right \}[/tex]
The outcomes in favour of Y will be:
[tex]Y=\left \{ A,C,E,F \right \}[/tex]

Actually Welcome to the Concept of the Similar Triangles.
Since here we can see that, similar triangles different by size of the side by 0.5 ration,
hence,the value of x = 0.5 times of MN
hence, x = 5/2
so the mixed fraction representation is given as,
[tex]2 \times \frac{1}{2} [/tex]
mixed fraction ration is 2(1/2)
===> hence option is B.)

Sum of interior angles is 540°
x = 90°
m∠B = 90°
m∠E = 100°
Step-by-step explanation:
to find the sum of the interior angles you take the number of sides, deduct two, and multiply by 180
a 5-sided figure would be (n - 2)·180° = 3(180) = 540°
add together all five angle measures and set equal to 540; combine like terms and solve for 'x'
220 + 130 + 130 + x + x + 10 = 540
350 + 2x + 10 = 540
2x + 360 = 540
2x = 180
x = 90

Step-by-step explanation:
A class of 195 students went on a field trip. They took 19 vehicles, some cars and some buses. If each car
holds 5 students and each bus hold 25 students, how many buses did they take?
Answer:
Number of cars = 14
Number of buses = 5
Step-by-step explanation:
Let
x = number of cars
y = number of buses
x + y = 19 (1)
5x + 25y = 195 (2)
From (1)
x = 19 - y
Substitute x = 19 - y into (2)
5x + 25y = 195
5(19 - y) + 25y = 195
95 - 5y + 25y = 195
- 5y + 25y = 195 - 95
20y = 100
y = 100/20
y = 5
Substitute y = 5 into (1)
x + y = 19
x + 5 = 19
x = 19 - 5
x = 14
Number of cars = 14
Number of buses = 5
Based on the number of vehicles and the number that each vehicle can take, the number of buses required is 4 buses.
There are 19 vehicles which take 5 students each. This means that the number of kids entering buses will be:
= 19 x 5
= 95 students
The students entering buses will be:
= Total number of students - Kids in vehicles
= 195 - 95
= 100 students
If each bus takes 25 students, the number of buses required is:
= 100 students / 25
= 4 buses
In conclusion, 4 buses were taken.

HELP ASAP WILL GIVE 30 points. A toy box measures 4 ft by 3 ft by 2 ft. Explain whether increasing
the height by four times, from 2 ft to 8 ft, would increase the volume
by four times.
Answer:
yes, the volume would be increased by 4
Step-by-step explanation:
the volume for a box is l x w x h
lets say l = 4, w = 3, and h = 2
this would give us a volume of 24
now calculate the new volume: l x w x 4h
4 x 3 x (4 x 2) = 96 which is 4 times bigger than 24
