Mike buys three cans of pop per week. This is one more than two fifths the number of cans of juice Mike buys per week. Determine the number of cans of juice Mike buys per week.
Answer:
5
Step-by-step explanation:
Mike buys 3 cans of pop per week and this is one more than 2/5 of the number of cans of juice that he buys.
Let the number of cans of juice be j and let the number of cans of pop be buys be p.
This means that:
p = 1 +2j/5
Make j subject of formula:
p - 1 = 2j/5
=> 2j = 5p - 5
j = ½(5p - 5)
p = 3 (from the question)
Therefore:
j = ½(5 * 3 - 5) = ½(15 - 5)
j = ½ * 10 = 5
Mike buys 5 cans of juice per week.
A box measures 4 units by 2 and 1/2 units, by 1 and 1/2 units. What is the greatest number of cubes with a side length of 1/2 unit that can be packed inside the box?
Answer:
120 cubes
Step-by-step explanation:
First we need to find the volume of the box and the volume of the cube.
Volume of box = 4 * 2.5 * 1.5 = 15 cubic units
Volume of cube = 0.5 * 0.5 * 0.5 = 0.125 cubic units
Now, to find how many cubes can be packed inside the box, we just need to divide the volume of the box by the volume of the cube:
number of cubes = volume of box / volume of cube
number of cubes = 15 / 0.125 = 120 cubes

Answer:
x = -27
Step-by-step explanation:
Apply the Distributive Property to 5(x - 4): 5x - 20.
Then we have 5x - 20 + 3x - 9x + 7.
Combining like terms, we get -x = 7 + 20 = 27, so that x = -27.
Ashton read 12 pages on Friday. He read 3 times as many pages on Saturday, and 14 more pages on Sunday.How many more pages did Ashton read over the three days?
Answer:
Ashton read 62 pages over the three days
Step-by-step explanation:
Given;
Ashton read 12 pages on Friday
He read 3 times as many pages on Saturday = 3 x 12 pages = 36 pages
He read 14 more pages on Sunday
The total number of pages read Ashton over the three days can be calculated as follows;
Total pages read by Ashton = 12 pages + 36 pages + 14 pages
Total pages read by Ashton = 62 pages
Therefore, Ashton read 62 pages over the three days

If a loan option had been available for your food truck for the $50,000 at 4% interest for 6 years instead of 4 would you have taken that option instead? Why or why not?
Answer:
It depends.
Step-by-step explanation:
For 6 years:
[tex]50000*(1.04)^6=\$63266[/tex]
On average, you would have to be profiting:
[tex]\frac{63266}{6}=\$10544[/tex] per year
For 4 years:
[tex]50000*(1.04)^4=\$58492[/tex]
On average, you would have to be profiting:
[tex]\frac{58492}{4} = \$14623[/tex] per year.
It would be better to have the longer term option - although you will be paying off more in total, you would be paying off a smaller portion of your earnings.
However, you may want to pay off the loan faster as you would no longer have to worry about it, and it would be cheaper to pay off over the shorter period.

A Cepheid star is a type of variable star, which means its brightness is not constant. The relationship between the brightness of a

brightness of the star, and Pis the number of days required for the star to complete one cycle. What is the absolute magnitude of

What is the magnitude of a star?magnitude, in astronomy, measures the brightness of a star or other celestial body. The brighter the object, the lower the number assigned as a magnitude. In ancient times, stars were ranked into six magnitude classes, the first magnitude class containing the brightest stars.
How do you find the magnitude of a star?Mv = m - 2.5 log[ (d/10)2 ]. Stars farther than 10 pc have Mv more negative than m, that is why there is a minus sign in the formula. If you use this formula, make sure you put the star's distance d in parsecs (1 pc = 3.26 ly = 206265 AU).

In triangle MNP, medians NQ and PR intersect at S. If PS = 8 and QS = 3 then which of the following is the value of NQ + PR
(1) 21
(2) 22
(3) 26
(4) 30
Answer:
(2) 22
Step-by-step explanation:
In the given triangle MNP, the medians are straight lines drawn from the angle to opposite side so as to divide the side into equal parts.
PS = 8 and QS = 3, thus;
PS = NS = 8 (congruent property of ΔRSN and ΔQSP)
QS = SP = 3 (congruence property)
So that,
NQ = NS + SQ
= 8 + 3
= 11
PR = PS + SR
= 8 + 3
= 11
Thus;
NQ + PR = 11 + 11
= 22
Therefore, NQ + PR = 22

we know that
applying the Pythagoras Theorem
c²=a²+b²
where
c=14 ft
a=8 ft
b=12 ft
case a)
if
c²=a²+b² C is a right angle
case b)
if
c²< (a²+b²) C is an acute angle

if
c² > (a²+b²) C is an obtuse angle
c²=14² 196
(a²+b²)=8²+12² 208
196 < 208
c² < (a²+b²) C is an acute angle
