1. Bill wants to buy coffee for his class at the LePhooPhoo Coffee Shop. He needs to buy 30 cups of coffee. The large coffees cost $4 and the medium coffees cost $3. If he spends $102 on coffee, how many of each size coffee did he buy?
Answer:
large = 12
medium = 18
Step-by-step explanation:
L + M = 30 => L = 30-M
4L+3M =102
substitute : L with M
=> 4(30-M)+3M =102
120-4M+3M = 102
- M = 102-120
-M = -18
=========> M = 18, L = 12

Answer:
allen= y=3/2+2 billy= y= 3/2+4
Step-by-step explanation:
ok both of the equation are (almost) the same except for the y intercepts.
y=mx+b... you are learning about that hopefully!
so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.
if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.
as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross because billy's line is higher then allens, billy's tree will always be higher

Find the height of a cylinder when the surface area is 1004.80 cm squared and the radius is 10 cm.
Step-by-step explanation:
[tex]volume =\pi {r}^{2}h[/tex]
[tex]area = \pi {r}^{2} [/tex]
CALCULATIONremember
[tex]\pi = 22 \div 7[/tex]
So, we will just place the area and equate it to the unknown volume including the height
1004.80 = 22/7 × 10× 10 × h
1004.80 = 314.26h
h = 3.197

what is the value of x? i need the work for it as well thank you so much!
Answer:
x=19
Step-by-step explanation:
okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.
6x+4=118
subtract 4 from both sides
6x=114
divide by 6 on both sides
x=19
Hope this helps!

Answer:
The 4 packe is better value.
Answer:
The 4 pack has better value.
Step-by-step explanation:
To find the toilet roll price, divide by the number of rolls.
2.04 ÷ 4 = 0.51
4.68 ÷ 9 = 0.52
0.52 > 0.51
So, the 4 pack has better value.
Have a wonderful day! :)

the diagram shows an isosceles triangle. all measurements are in cm.
3x-5 19-x
2x
work out the perimeter of the triangle
Answer: 38
Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6
Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12
Two equal sides are 13 and base 12
Perimeter is 13 + 13 + 12 = 38 units
Answer is: 38
The perimeter of the given isosceles triangle is 38 cm.
What is the perimeter of an isosceles triangle?The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;
We can say that the perimeter of an isosceles triangle is:
P = 2a + b
where;
a = sides of the base anglesb = third side3x - 5 = 19 - x
3x + x = 19 + 5
4x = 24
x = 24/4
x = 6
The perimeter of the isosceles triangle is:
= 3x - 5 + 19 - x + 2x
= 3(6) - 5 + 19 - 6 + 2(6)
= 18 + 8 + 12
= 38 cm

2. A(an) ______________of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Answer:
A(an) altitude of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)
Step-by-step explanation:
AN ALTITUDE - An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.
Hence , the answer is an altitude .

What is the formula for prism
Answer:
The formula for the volume of a triangular prism is:
V=(l)(w)(h)
Where l is the length of the triangle, w is the width of the triangle, and h is the height of the prism
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.
