Luz borrowed
money from her bank for home repairs, the principal was $25,000, the rate
was 15% the time was 6 years. How
much interest will she pay and what is the total amount she will have to
pay back? (Principal and interest).
The total amount accrued, principal plus interest, from simple interest on a principal of $25,000.00 at a rate of 15% per year for 6 years is $47,500.00.
Answer:
I = $22,500.00
A = $47,500.00
Simple interestGiven Data
Principal = $25000
Rate = 15%
Time = 6 years
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 15%/100 = 0.15 per year.
Solving our equation:
A = 25000(1 + (0.15 × 6)) = 47500
A = $47,500.00
I = A - P = $22,500.00

Charles sells each pen for 70p but he only manages to sell
2
3
of the pens.
How much profit did he make?
Answer:
£122
Step-by-step explanation:
Total no. of pens :- 60× 14= 840
Cost of all pens :- £270
Total no. of pens sold :- 560
Cost of those pens :- £392
Profit = £122Charles made a profit of £122, By selling (2/3)rd of his pens.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Charles buys 60 packs of pens and there are 14 pens in each pack.
If each pack costs £4.50.
So, The Total cost is,
= £(60×4.50).
= £270.
The total number of pens is,
= (14×60).
= 840, And he manages to sell (2/3) of it which is,
= (2/3)×840.
= 560.
Now, The total money made by him is,
= 540×0.7.
= £392.
Therefore, The profit he made is £(392 - 270) = £122.

Please answer ASAP! I am very confused. Please explain steps if possible.
Answer:
943 exponent 14
Step-by-step explanation:
The question deals with indices(exponents). Therefore,all laws of indices related to the question must be applied to clearly solve and understand the question.
so,(943 exponent 78 · 943 exponent 1)/943 exponent 65
· means multiplication so simply,(943 exponent 78 × 943 exponent 1)/943 exponent 65
The laws of indices clearly state that, when two indices of the same base are multiplying, you add their exponents and when dividing,you subtract their exponents.
As all the indices have the same base which is "943", we can quickly add & subtract the exponents.
(Leaving base out of calculation now to make it easier to directly deal with exponents)
(78+1)-65(From the rules)
79-65=14,which means 943 exponent 14
∴The answer is 943 exponent 14
Mike is building storage boxes. Each box will have a length of 5 feet, a width of 412 feet, and a height of 312 feet. A pint of paint covers 50 square feet.
How many pints of paint does Mike need to buy in order to paint 4 boxes?
9 pints
7 pints
6 pints
5 pints
Answer:
Step-by-step explanation:
The question contains typos as I believe the boxes should be 5x4.2x3.2 in dimensions instead.
Assuming that and all 6 faces of each storage boxes will be painted, the surface area of each box is:
= (5*4.2*2) + (4.2*3.2*2) + (3.2*5*2)
= 100.88 square feet
4 boxes will have a total surface area of
100.88*4
= 403.52 square feet
Each pint of paint covers 50 square feet so a total of
403.52/50 = 8.07 or
9 pints is needed.

What are trigonometric identities?
Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
we need to first know the signs of the trigonometric functions in each of the 4 quadrants going in an anti-clockwise direction.
In the first quadrant, the cot, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sine is positive.
In the third quadrant going anti-clockwise, only tangent is positive.
In the fourth quadrant going anti-clockwise, only cosine is positive.
We are told that the
sinθ < 0 and cos θ > 0.
This means that sine is negative and cosine is positive.
Looking at the rule, it is clear that the angle is in the fourth quadrant.

After measuring the heights of 7 people, they have an average height of 156cm. after
measuring the heights of 8 people they have an average height of 158cm. how tall is
the 8th person?
Answer:
8th Person = 172 cm tall
Step-by-step explanation:
( a + b + c + d + e + f + g )/7 = 156
a + b + c + d + e + f + g = 1092 total size
----------------------------------------------------------
now they measured 8 people (a + b... g) + h, but we know the total size of the other 7 = 1092
a + b + c + d + e + f + g + h
( 1092 + h )/8 = 158
1092 + h = 158*8
h = 1264 - 1092
h = 172
-----------------------------------
the 8th person is 172 cm tall
