When solving: 1,175 ÷ 5, using partial quotients, how would you decide which power of 10, when multiplied by 5, should be subtracted first?
I need a step by step example please
Using partial quotient, the place value while subtracting is determined by the dividend.
The place value should never be more than the dividend not up to a tens place value less than the dividend's place valueHow to perform division using partial quotientsdivisor dividend quotient multiplication subtraction new dividend
5 1175 200 200 * 5 = 1000 1175 - 1000 = 175
5 175 30 30 * 5 = 150 175 - 150 = 25
5 25 5 5 * 5 = 25 25 - 25 = 0
The quotient is then added as
= 200 + 30 + 5
= 235
Assuming the quotient was written 2. While subtracting, the dividend for the first value (1175) is in thousands. placing the the 2 in thousands makes it more than the dividend hence the 2 should be in hundreds
1175 - 2000 incorrect
1175 - 200 correct

which point is on the line 4y-2x=0
Answer:
(2,1)
Step-by-step explanation:
The line 4y - 2x = 0 can be written in slope-intercept form as y = 1/2x.
So any point that satisfies this equation will lie on the line. For example, the point (2,1) satisfies the equation:
4(1) - 2(2) = 0
So the point (2,1) is on the line.
If we use 10 g of corn starch in a 15 cm mold- How much corn starch do we use in a 24 cm mold?
16g corn starch would be used in a 24 cm mold
Explanation:10g of corn starch = 15 cm
let the number of corn starch in 24cm mold = y
10g = 15cm
y = 24cm
cross multiply:
10g(24cm) = y(15cm)
240g = 15y
divide both sides by 15:
240g/15 = 15y/15
y = 16
Hence, 16g corn starch would be used in a 24 cm mold
Drew is driving out of state to go to a theme park. The total distance he is driving is 500.34 miles. He has driven 0.45 of the
distance so far, Drew calculated that he has driven 250.17 miles.
Is Drew's calculation reasonable or not? Explain your answer. If his calculation is not reasonable, determine the number of miles
Drew has actually driven.
The calculation is not reasonable, because 0.45 is less tha 1/2 ( 0.50) and what he has for an answer is half the distance ( 250.17 is 1/2 of 500.34).
To find actual mileage, multiply by 0.45:
500.34 x 0.45 = 225.153 miles.
Round the answer as needed.
John drove from here to San Antonio which is 180 miles away in 3 hours. Which rate is equivalent to
the rate at which John drove to San Antonio?
The rate that is equivalent to the rate at which John drove to San Antonio is 60 miles per hour
Which rate is equivalent to the rate at which John drove to San Antonio?From the question, we have the following parameters that can be used in our computation:
John drove from here to San Antonio which is 180 miles away in 3 hours.
This means that
Distance = 180 miles
Time = 3 hours
Using the above as a guide, we have the following:
Speed = Distance/Time
Substitute the known values in the above equation, so, we have the following representation
Speed = 180/3
Evaluate
Speed = 60
Hence. the rate that is equivalent to the rate at which John drove to San Antonio is 60 miles per hour

a jewllery shop is having a sale
The original price of the bracelet was £1400.
What do you mean by Percentage ?Percentage is a way of expressing a proportion or a fraction as a part of 100. It is denoted using the symbol "%". For example, 50% means 50 out of 100, or half, while 25% means 25 out of 100, or one-quarter.
We can start by using the information given to set up an equation that relates the original price of the bracelet with the sale price and the percentage reduction:
original price x (100% - 70%) = sale price
Simplifying the percentage reduction:
original price x 30% = sale price
Substituting the given sale price (£420):
original price x 30% = £420
To solve for the original price, we need to isolate it on one side of the equation. We can do this by dividing both sides by 30% (which is the same as multiplying by 100/30 or 10/3):
original price = sale price / 30% = £420 / 30% = £1400
Therefore, the original price of the bracelet was £1400.

Answer:
1.5
Step-by-step explanation:
5/8 + 7/8= 1.5 or 1 1/2
Answer:
Read below.
Step-by-step explanation:
First fridge: \(\frac{8}{8} -\frac{5}{8} =\frac{3}{8}\)
Second fridge: \(\frac{8}{8} -\frac{1}{8} =\frac{7}{8}\)

At the local Theatre of the Arts, tickets cost $4 for children and $5 for adults. In the opening Saturday night of a play, the theater made $540. The second day was a matinee and the prices were lower for children at $3 and the same price as Saturday for adults. They made $440 at the matinee.
A) Write a system of equations in standard form that represents the prices at the Theatre on Saturday and the second day.
B) Rewrite the system of equations in slope-intercept form. What are the y-intercepts of both equations?
A. The system of equations in standard form is: 4x + 5y = 540 and 3x + 5y = 440.
B. The y-intercept of the equation representing the prices on Saturday night is 108, and the y-intercept of the equation representing the prices at the matinee on the second day is 88.
A) Let's define the variables:
Let x represent the number of children attending.
Let y represent the number of adults attending.
On Saturday night:
The equation for the revenue generated on Saturday night is:
4x + 5y = 540 (since children's tickets cost $4 and adults' tickets cost $5, and the total revenue is $540).
Matinee on the second day:
The equation for the revenue generated at the matinee is:
3x + 5y = 440 (since children's tickets cost $3 and adults' tickets still cost $5, and the total revenue is $440).
Therefore, the system of equations in standard form is:
4x + 5y = 540
3x + 5y = 440
B) Let's rewrite the system of equations in slope-intercept form:
On Saturday night:
4x + 5y = 540
Rearranging the equation, we get:
5y = -4x + 540
Dividing both sides by 5, we get:
y = (-4/5)x + 108
The y-intercept of this equation is 108.
Matinee on the second day:
3x + 5y = 440
Rearranging the equation, we get:
5y = -3x + 440
Dividing both sides by 5, we get:
y = (-3/5)x + 88
The y-intercept of this equation is 88.

Answer:
A(3) = 13
A(4) = 18
A(10) = 48
Step-by-step explanation:
This seems like a plug and play.
Starting with A(3). Everywhere you see an n, you'll replace it with a 3, as follows;
3 + (3-1)(5) = ?
We'll solve it step by step. First is 3-1. That's 2, bringing it to

a car uses an average of 6 litres of fuel per 100kilometres if the car uses 9 litres of fuel what is the distance covered?
Answer:
150 kilometres
Step-by-step explanation:
Imagine it as a ratio 6 : 100
If they have given you the first side which is 9 you need to figure out the other side (9 : ?)
To do this you simply need to figure out how you get from 6 to 9 which is times by 1.5
Then to find the other side you do the same as they are proportional to each other
So 100 times by 1.5 which is 150
This gives you the answer that you can travel 150 kilometres with 9 litres of fuel
Determine the largest power of 10 that is a factor of the following numbers (equivalently, the number of terminal 0's, using ordinary base 10 representation):(a) 50!.
(b) 1000!.
The largest power of 10 that is a factor of 1000! is 5^249, or 10^249.
(a) To find the largest power of 10 that is a factor of 50!, we need to count the number of factors of 5 in 50! since each factor of 5 contributes at least one factor of 10.
There are 10 multiples of 5 in 50!, namely 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50. Each of these contributes one factor of 5. There are also 2 multiples of 25 (25 and 50), each of which contributes an additional factor of 5. Therefore, the total number of factors of 5 in 50! is 10 + 2 = 12.
Since each factor of 10 contains one factor of 5 and one factor of 2, we also need to count the number of factors of 2. It is clear that there are more factors of 2 than factors of 5, so we only need to count the factors of 5. Therefore, the largest power of 10 that is a factor of 50! is 5^12, or 10^12.
(b) To find the largest power of 10 that is a factor of 1000!, we follow the same reasoning as in part (a). The number of factors of 5 in 1000! is:
⌊1000/5⌋ + ⌊1000/25⌋ + ⌊1000/125⌋ + ⌊1000/625⌋ = 200 + 40 + 8 + 1 = 249

The area of the composite figure whose vertices have the (2,-2), (2,1), (4,2), (6,2), (4,-1) coordinates is 6 square units
We first need to plot all the given points A (2,-2), B (2,1), C (4,2), D (6,2)and E (4,-1) which is coordinate geometry
After joining the Points which is a pentagon and it can be divided in two shapes one is triangle CDE and a quadrilateral ABCE
Using the distance formula
BC = \(\sqrt{(y2-y1)^{2}+(x2-x1)^{2} }\) = \(\sqrt{(2-1)^{2} + (4-2^{2} }\) = √5
Since BC = AE and BC ll AE , we can say ABCE is a parallelogram
area of a parallelogram = base × Altitude
= 2 × 2= 4
Area of triangle CDE where CD is perpendicular and CE is the base
= 1/2 ( 2×2)
= 1/2 (4)
= 2 square units
So the area of ABCDE = Area of ABCE + area of CDE
= 4 square units + 2 square units
= 6 square units
