Answer:
2 plain folders and 7 folders with cartoons
Step-by-step explanation:
Given data
Let the number of plain folders be x
and the number of folders with cartoons be y
x+y=7------------1
x+2y=12----------2
from 1
x= 7-y
put this in 2
7-y+2y=12
7+y= 12
y= 12-7
y=5
Put y=5 in 1
x+5= 7
x= 7-5
x= 2
Hence Ayin bought 2 plain folders and 7 folders with cartoons

Karl invests $35,000 for 8 years in an account paying 7% compounded daily. Find
the annual percentage yield (APY) to the nearest hundredth of a percent. *
a.9.38%
b.12.72%
c.10.14%
d.11.36%
Answer:
principal (p)=$35000
time(t)=8years
rate ( r)=7%
Step-by-step explanation:
compounded amount(c.a)=p((1+r/100)^t )=$35000((1+7/100)^8)=$60136.5compound interest gain=$60136.5-$35000=$25136.5Karl gain interest in 1 year=$35000((1+7/100)-1)=$2450gain % in 1 year=$2450/$25136.5×100%=9.74%Write the equation of the line in fully simplified slope-intercept form.

What is the value of x in the figure below?
70°
xo
115°
A 45°
B. 550
C. 57.59
D. 22.50
Answer:
A. 45°
Step-by-step explanation:
By exterior angle theorem:
x + 70° = 115°
x = 115° - 70°
x = 45°
Answer:
x= 45°
Step-by-step explanation:
triangles degrees all together are always 180°
x≠180°
a straight line is also 180°
180°-115°= 65°
70°+65°= 135°
180°-135°= 45°

Solve: -36 = 9w w = _____
Answer:
w = -4
Step-by-step explanation:
You have to do -36 and divide it by 9 and you get -4 = w
2. Solve: 2p+4= - 50
2p + 4= -50

What is least amount of surface area possible on a rectangular prism with a volume of 64 cubic inches? What are the dimensions of this rectangular prism?
Answer: 64=s3
Step-by-step explanation: V=s3
64=s3
find the cubic root of each side
3√ 64=s4=s
so the side of the cube is 4 cu in.
The surface area of a cube is
SA=nA
where SA
is surface area, n
is the number of faces, and A
is the area of one face.
Te area of one face (A) is s2 so

In order to help her save money for college, Latasha's grandparents deposited $10,000 into a savings account five years ago. Latasha has not made any withdrawals or deposits since then. The interest rate on the savings account is 3.75% each year.
Using simple interest, how much interest has accrued in Latasha's savings account?
What is the total amount in Latasha's savings account?
Answer:
$11,875
Step-by-step explanation:
3.75×5 = 18.75%
[tex]\frac{18.75}{100}[/tex]×10000 = 18.75 × 100 = 1875 (we cut the zeros so that it will be easier to solve the equation)
10,000 + 1875 = $11,875 after 5 years
$1875 has accrued in Latasha's savings account
$11,875 is the total amount in Latasha's savings account after 5 years
A rectangular plaque at a historical museum is 5/6 and 2/3 yard wide how much is the plaque longer than it is wide
Answer:
1/6 yard
Step-by-step explanation:
A rectangular plaque at a historical museum is 5/6 and 2/3 yard wide how
Given data
Length of plaque= 5/6 yard
Width of plaque= 2/3 yard
The difference between the Length and the width is
=5/6-2/3
=5-4/6
=1/6 yard
Hence the Lenght is 1/6 yard longer than the width

If x = 8, what is the value of 4x + 6?
I NEED HELP! I’m on a test!!
Answer:
=38
Step-by-step explanation:
Use substitution :3
4(8)+6=38
substitute x to 8 then calculate!
There you'll get your answer.
the required value of expression 4x + 6 is 38 when x = 8.
If x = 8, what is the value of 4x + 6 to be determine.
In mathematics, it deals with numbers of operations according to the statements.
The equation is the relationship between variables and is represented as y = 4x +8 is an example of a polynomial equation.
Here, the expression is given as,
y = 4x + 8
now we have x = 8, put this x in y
y = 4(8) + 6
Solving the equation using the PEMDAS rule of mathematics
1St open the parenthesis of 8 then multiply this 8 by 4.
y = 4*8 +6
y = 32 + 6
Now adding 32 and 6 will give 38
y = 38
Thus, the required value of expression 4x + 6 is 38 when x = 8.
