Jackie purchases 100 bracelets from a wholesaler at $10 each and the cost totals $1,000. If
Jackie does a markup of 40%, what will the markup amount be? What will the price of each
bracelet be?
Using proportions, it is found that:
The markup amount is of $400.The price of each bracelet is of $14.What is a proportion?A proportion is a fraction of a total amount.
In this problem, the markup is of 40% over an amount of $1000, hence:
0.4 x $1000 = $400.
Considering the markup, 100 bracelets will be sold for $1,400, hence, the price of each bracelet will be given by:
$1,400/100 = $14.

Jackson said that he made a triangle that had side lengths of 6 units, 6 units and 14 units. Is this a possible triangle?
Answer:
The triangle will not be possible.
this is because two side lengths can't expand 14 units.
in order for the triangle to work, the sum of the two short side lengths must be greater than the longer side.
however, 6+6 does not equal 14 it equals 12 this means that the triangle is not possible

Combine like terms then solve for d. i will give brainliest please explain so i can know how to do it
Answer:
7d=30
d=18.5714
Step-by-step explanation:
Answer:
d=20
Step-by-step explanation:
4d & 3d are like terms because they both have a variable.
20 & 5 are alike because they both don't have a variable.
First you would add 4d and 3d together, and you will get 7d.
4d+20+3d-5=155
7d+20-5=155
Next you can subtract 5 from 20.
7d+15=155
Then you subtract 15 from both sides of the equation.
7d=140
Then you divide by 7 on both sides.
And you are left with d=20

Answer:
x = 28
Step-by-step explanation:
From the figure attached,
In ΔABC and ΔADC,
AB ≅ AD [Given]
BC ≅ CD [Given]
AC ≅ AC [Reflexive property]
ΔABC ≅ ΔADC [SSS property of congruence]
Therefore, ∠ABC ≅ ∠ADC [CPCTC]
(4x + 13)° = (5x - 15)°
15 + 13 = 5x - 4x

explain why 2^0 is equal to 1.
Answer and Step-by-step explanation:
Anything that is to the power of 0 is equal to 1. This is why 2 to the power of 0 is equal to 0.
0 is the only number such that for any number x, x + 0 = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
#teamtrees #PAW (Plant And Water)
Answer:
Step-by-step explanation:
multiply by 2^x
[tex]2^0 \times 2^x=2^{0+x}=2^x\\[/tex]
when you multiply any number by 1 ,you get the same number.
here when you multiply 2^x by 2^0 ,you get 2^x
Hence 2^0=1

Car A went 60km in 5/6hours while car B when 54km in 2/3hours which car was faster? How many times Faster?
Answer:
Car B is 1.125 times faster than Car A.
Step-by-step explanation:
Speed = Distance / Time
Car A speed = Car A distance / Car A time
= 60 / (5/6) = 72km / hr
Car B speed = Car B distance / Car B time
= 54 / (2/3) = 81 km /hr
Car B is 81 / 72 ie = 1.125 times faster than Car A.
