Answer:
244^2-156^2 hi this is in the form p^2-q^2=(p+q)(p-q) now, (244+156)(244-156) =(400)(88)=35,200answer.
Asli has a number of coins in a box. There are thirty-four 25 cent coins,
a
eighty-five 10 cent coins, seventy-two 5 cent coins and nine 1 cent coins.
As a percentage, write down the ratio of:
a) 25 cent coins to the total
b) 10 cent coins to 25 cent coins
c) 1 cent coins to 5 cent coins
d) the total number of coins to 1 cent coins.
Answer:
Step-by-step explanation:
No. of 25 cent coins = 34
No. of 10 cent coins = 85
No. of 5 cent coins= 72
No. of 1 cent coins = 9
Total sum of coins = 200
Percentage of 25 cent coins = (34/200)*100
= 17 %

A retailer obtains a bank loan of € 83,300, with an interest rate 4.5%, to be repaid after 150 days.
> Calculate the interest due on expiry of the loan.
Answer:
Step-by-step explanation:
Calculation
Divide your interest rate by the number of payments you'll make that year. ...
Multiply that number by your remaining loan balance to find out how much you'll pay in interest that month. ...
Subtract that interest from your fixed monthly payment to see how much in principal you will pay in the first month.
Triangle E B C is shown with its exterior angles. Line E C extends through point F. Line C B extends through point A. Line B E extends through point D. Which statements regarding the diagram of ΔEBC are true? Select three options. ∠BEC is an exterior angle. ∠DEC is an exterior angle. ∠ABE and ∠EBC are supplementary angles. ∠BCF and ∠DEC are supplementary angles. ∠BEC is a remote interior angle to exterior ∠BCF.
Answer:
2, 3, 5 are true statements
Step-by-step explanation:
A diagram of the geometry is helpful. Our understanding of your description is shown in the first attachment. The second attachment shows how the various angles relate to each other. An exterior angle and its adjacent interior angle are a linear pair, so are supplementary.
__
1. BEC is an exterior angle -- False, it is an interior angle
2. DEC is an exterior angle -- True
3. ABE and EBC are supplementary -- True, they are a linear pair
4. BCF and DEC are supplementary -- False, they are unrelated exterior angles
5. BEC is a remote interior angle to BCF -- True

There are 9 students in a service club. The club is making gift baskets for children in a hospital. Each club member donated 4 children’s books for the baskets. Each club member also donated an equal number of toys. A total of 63 items were collected for the baskets. Which linear equation can you use to find how many toys each club member donated?
Answer:
9x + 36 = 63
Step-by-step explanation:
Let x represent the number of toys that each club member donated.
There are 9 students in a service club.
If each club member donated 4 children's books for the baskets, it means that the total number of books donated by the club members would be
9 × 4 = 36
If each club member also donated an equal number of toys. It means that the total number of toys donated by the club members would be
9 × x = 9x
A total of 63 items were collected for the baskets. Therefore, the linear equation that you can use to find how many toys each club member donated would be
9x + 36 = 63

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{19\sqrt{3} }[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )

y = 19

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{19\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
[tex]\sqrt{3}[/tex] × x = 38[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

A set of pens sells for $3. 75 and costs $1. 50 to make. Thirty percent of the profit (the difference between the purchase price and the amount it costs to make) from each set of pencils goes to a school. If 600 sets are sold, what is the amount of money that will go to the school?
Answer:
$405
Step-by-step explanation:
3.75-1.50=2.25
2.25 x 600 = 1350
30 % of 1350 is 405 so it would equal $405

What two numbers multiply to -42 but also add up to -11
Answer:
3 and -14
Step-by-step explanation:
Find the factors of -42 and add them to see what they give:
1 × -42 = 42, -41
2 × -21 = 42, -19
3 × -14 = 42, -11
6 × -7 = 42, -1
The second to last is right so the numbers are 3 and -14

I don't really get alot of help but help me on this one Find the volume pls
Answer:
C. 112 cubic inches
Step-by-step explanation:
Two solve this weird-looking house problem, first let's see what it is made of.
Split the area into two volumes.
V = 1/3lwh is the volume for a triangular prism and V = lwh is the volume for a rectangular prism.
Let's now solve for the triangular prism.
The length and width are the same as that of the cube. The cube's length and width is 4 in.
V = 1/3(4)(4)(6) = 32 cubic inches
Now Solve for the cube.
V = lwh = 4(4)(5) = 80 cubic inches
Total Volume = 80 + 32 = 112 cubic inches

the sum of ages of Jamal and his father is 40 years.After 4 years,the age of the father will be triple the age of his son.Find the age of Kamal and his father
Answer:
The age of Jamal is 8 years.
And the age of his father is 32 years.
Step-by-step explanation:
=> let the age of Jamal be x and his father's age be y
=> so , A.T.Q ,
x+y = 40....i)
Find the value of y from here , that's y = 40-x .....
Now, After 4 years ,
=> 3(x+4) = (y+4)
=> 3x+12 = y+4
=> 3x+8 = y ...ii)
putting the value of y in equation ii)
=> 3x+8 = 40-x
=> 3x+x = 40-8
=> 4x = 32
=> x = 8
now ,
=> y = 40-x
=> y = 40-8
=> 32
The intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. Suppose intensity is 8000 units at a distance of 2 miles. What will the intensity be at a distance of 12 miles? Round your answer to the nearest unit. A. 205 units b. 222 units c. 248 units d. 186 units.
The intensity of soundwave at a distance of 12 miles is 222.22 miles.
What is Directly proportional and inversely proportional?
The link between two variables whose ratio is equal to a constant number is known as a direct proportional, while the multiplication of two variables whose ratio is equal to a constant number is known as an inversely proportional.
It is given that the intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. therefore, the relation between the intensity of the radio wave(I) and distance(r) can be written as,
[tex]I\propto \dfrac{1}{r^2}\\\\\\I=k \dfrac{1}{r^2}[/tex]
Now, it is stated that the intensity of the radio wave at a distance of 2 miles is 8000 units, therefore, substituting the value in the above equation to get the value of the constant,
[tex]I=k\dfrac{1}{r^2}\\\\8000=k\dfrac{1}{2^2}\\\\8000=k\dfrac{1}{4}\\\\k = 8000 \times 4 = 32,000\rm\ units[/tex]
Thus, the value of the constant k is 32,000 units, and the equation of the intensity of the radio signal can be written as,
[tex]I=\dfrac{32,000 }{r^2}[/tex]
Further, the intensity of soundwave at a distance of 12 miles will be equal to,
[tex]I=\dfrac{32,000 }{r^2}\\\\I=\dfrac{32,000 }{12^2}\\\\I=\dfrac{32,000 }{144}\\\\I = 222.22\rm\ units[/tex]
Hence, the intensity of soundwave at a distance of 12 miles is 222.22 miles.

Answer:
Slope is 3/4
Step-by-step explanation:
Each point given is an x and a y, like this (x, y)
For the top number (numerator) of your answer, subtract the y's from both points.
On top: 9 - 3
On the bottom (denominator) subtract the x's.
Below: 5 - -3
So slope is:
9-3 / 5 - -3
6/8
Simplify
