Answer:
5/14Step-by-step explanation:
5/6×3/7 =5/2×1/7=5/14There are 28 Year 8 students going on the ski trip, out of the 45 students going. Write this proportion as a percentage. Give your answer correct to 1 decimal place.
Answer:
62.2%
Step-by-step explanation:
We are told in the question that:
The total number of students going = 45 students
The number of year 8 students going for the ski trip = 28 students
The proportion is :
28/45
Converting this proportion to a percentage.
28/45 × 100
= 0.6222222222222222 × 100
62.222222222%
Approximately to 1 decimal place is
62.2%
Investors buy a studio apartment for $240,000. Of this amount, they have a down payment of $60,000.
a. Their down payment is what percent of the purchase price?
b. What percent of the purchase price would a $12,000 down payment be?
Answer:
A) 4%
B) 20%
Step-by-step explanation:
As, A) we will take 60,000/240000 x 100% so that we can find the percentage.
So the answer = 4%
B) for $12,000, 12, 000/240000 x 100%
Answer = 20%
A) The percentage is 4%
B) The percentage is 20%
Given that,
Investors buy a studio apartment for $240,000. Of this amount, they have a down payment of $60,000.calculation:(a)
[tex]= 60,000\div 240000[/tex]

- If the exterior angle of the triangle measure 133°, and its remote interior
angles measure x° and (2x-5)°, what is the value of x?
a. x = 61.7°
b. x = 133°
c. x = 47°
d. x = 46°
Answer:
D
Step-by-step explanation:
Mathematically;
the exterior angle is the sum of the two remote interior angles
Thus;
x + 2x-5 = 133
3x-5 = 133
3x = 133 + 5
3x = 138
x = 138/3
x = 46

A savings bond currently made Jamar $2,112.64 worth of interest in 7 years. If the investment gained 5.5% annual simple interest each year, approximately how much was the bond originally bought for?
A.$1381.81
B.$2673.21
c.$4903.23
D.$5487.36
Answer:
D; it was bought for $5,487.36
Step-by-step explanation:
Let the investment amount be $x
We use the formula for simple interest to get the interest
(2112.64-x) = (x * 5.5 * 7)/100
211264-100x = 38.5x
138.5x = 211264
x = 211264/138.5
x = 5,847.36

The price of pears can be determined by the equation P=0.54n, where P is the price and n is the number of pears. What is the constant of proportionality (unit rate)?
PLEASE NEED THIS ASAP!!!!!!!!!!
Answer:
The constant of proportionality is 0.54
Step-by-step explanation:
Given:
P = 0.54n
Where,
P = price of pears
n = number of pears
What is the constant of proportionality (unit rate)?
The constant of proportionality is 0.54
This means a unit of pears cost $0.54
If the number of pears bought, n = 50
Then,
P = 0.54n
When n = 50
P = 0.54(50)
= 27
P = 27 when n = 50
The correct answer is:
The constant of proportionality is 0.54

Carlo and Helen spend the same amount of money on art supplies. Carlo buys 4 glue
sticks and spends $3 on glitter. Helen buys 2 glue sticks, and she spends $3.75 on tape
and $2.75 on paint. What is the cost, x, of each glue stick?
Since we don't have a total cost we will write an equation that will allow us to find the cost of x. The equation is 4x= 2x + $3 + $3.75 + $2.75. Now that we have our equation we are going to start by adding 3, 3.75, and 2.75. When added together, they come out with a total of 9.5. Now the equation becomes 4x= 2x + $9.50. Since we have our new equation we are going to subtract 2x from both sides of the equation. We now have the equation 2x= $9.50. Finally, you will divide both sides by 2. This leaves us with the final outcome x= $4.75. This means that one glues stick cost $4.75. Let's check by substituting $4.75 as the value of x in the expressions 4x is Carlo's total and 2x + $3 + $3.75 + $2.75 is Helen's total. First we do 4x, 4 multiplied by 4.75 equals 19, so Carlo spent $19 on art supplies. Now we do 2x + $3 + $3.75 + $2.75, which is 9.5 added to 9.5 and equals 19. So Helen spent $19 on art supplies. This proves that the cost of one glue stick, x, is equal $4.75.

A swimming pool is 30 feet wide and 50 feet long. If it is surrounded by square tiles, each of which is 1 foot by 1 foot, how many tiles are there surrounding the pool?
Answer:
164 tiles
Step-by-step explanation:
Per the above details, we will require tiles along all the sides of the swimming pool ,hence the circumference of the pool is denoted as;
= 2(wide + long)
Wide = 30 feet
Long = 50 feet
Circumference = 2(30 + 50)
Circumference = 2(80)
Circumference = 160.
It means that minimum of 160 tiles of 1 ft length is required, however, we will also require tile on each of the corners(4), total equals
= 160 + 4
= 164 tiles
A total of 164 tiles are there surrounding the pool.
what's the equivalent expression of 2(4x+1)
Answer:
Step-by-step explanation:
Are there any choices?
2(4x+1)
8x+2
The expression equivalent of 2(4x+1) would be; 8x+2
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need to find the expression into an equivalent.
Therefore, given expression is
2(4x+1)
This expression could also be given by;
2(4x+1) = 2(4x ) + 2
Now, we know that:
2(4x+1) = 8x+2
Hence, the expression equivalent of 2(4x+1) would be; 8x+2

What is the image of (-3, -3) after a dilation by a scale factor of 1/3 centered at the
origin?
The image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin is (-1, -1).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, the image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin will be,
= (-3/3, -3/3).
= (-1, -1).
It has been shrinked by a factor of three the image became smaller.

How many moles are in the 500.0g lump of coal (which is made of carbon) that you received in your Christmas stocking last year?
How many carbon atoms are in this 500.0g lump of coal?
Answer:
Number of moles = 41.67 (Approx)
Number of carbon atom = 250.97 x 10²³ (Approx)
Step-by-step explanation:
Given:
Amount of carbon = 500 g
Find:
Number of moles
Number of carbon atom
Computation:
Number of moles = 500 / Atomic number of weight
Number of moles = 500 / 12
Number of moles = 41.67 (Approx)
Number of carbon atom = Number of moles x Avogadro number
Number of carbon atom = 41.67 x 6.023 x 10²³
Number of carbon atom = 250.97 x 10²³ (Approx)

Step-by-step explanation:
On the left, we have 3 positive x bars and 8 1s.
Hence, the left can be represented by the following expression:
[tex]3x+8[/tex]
On the right, we have 4 positive x bars and 6 1s.
Hence, the right can be represented by the following expression:

The two are equivalent. Therefore:
[tex]3x+8=4x+6[/tex]
Solve for x. Subtract 6 from both sides:
