the ratio of black bags to blue bags is 5 to 3 if there are a total of 10 black bags then how many blue bags are there
Answer:
6
Step-by-step explanation:
3 times 2
Is 6 and 5 times 2 is 10
Final answer:
To find the number of blue bags, we calculate based on the 5 to 3 ratio with 10 black bags. Each part corresponds to 2 bags, hence there are 6 blue bags.
Explanation:
The question concerns the calculation of the quantity of blue bags based on a given ratio to the quantity of black bags. If the ratio of black bags to blue bags is 5 to 3, and there are a total of 10 black bags, then we can set up a proportion to find the number of blue bags.
To solve this, we assume the number of black bags (5 parts) equals 10, which means each part corresponds to 10 / 5 = 2 bags. Since there are 3 parts of blue bags in the ratio, we then multiply the number of bags per part by 3 (the number of blue parts), which gives us 3 * 2 = 6 blue bags.

Write a word problem using 7 groups. Solve your problem?
A real-world problem using 7 groups can be illustrated like a builder constructing 7 buildings each requiring 15 bricks per day. Multiplying these, 7 times 15 gives us 105, which is the total number of bricks needed each day.
Explanation:Consider a scenario where a builder is constructing 7 buildings. Each building needs 15 bricks per day for construction. We can therefore write a multiplication problem to find out how many total bricks are needed each day.
So, 7 (groups of buildings) multiplied by 15 (bricks per building) equals a total daily brick requirement. To solve this, you simply multiply 7 by 15 which equals 105 bricks needed each day.
This is a simple real-world problem to help understand the concept of multiplication as repeated addition. Here, you're adding 15 bricks 7 times since there are 7 buildings.

Two times a number, plus five, equals the number, minus five.
Find the number and type it in the box.
Answer:
Answer:
x= -5
Step-by-step explanation:
let the number be x.
2x+5= -5 ====> equation
2x= -5-5. (shifted the +5 to the other side)
2x= -10
x= -10/2 ( shifted 2 on the other side as it was multiplying with x)
x= -5
Final answer:
To solve the equation 'two times a number, plus five, equals the number, minus five,' we set up and simplify the algebraic equation 2x + 5 = x - 5, which ultimately gives us the number x = -10.
Explanation:
The problem states that two times a number, plus five, equals the number, minus five. To find the number, we can set up the equation 2x + 5 = x - 5, where x represents the number we're trying to find.
Step 1: Start by subtracting x from both sides of the equation to get all the x terms on one side and the constant terms on the other side. The equation then becomes: 2x - x + 5 = x - x - 5, simplifying to x + 5 = -5.Step 2: Next, we subtract 5 from both sides of the equation to solve for x: x + 5 - 5 = -5 - 5, which simplifies to x = -10.Therefore, the number we were trying to find is -10.

on dividing $200 between A and B such that twice of A's share is less than 3 times than B's share by $20
Answer:
Share of A is $116 and Share of B is $84.
Step-by-step explanation:
Let the share of A be [tex]x[/tex]
Let the share of B be [tex]y[/tex]
Given:
$200 is shared between A and B
So, [tex]x+y =\$200\ \ \ \ equation \ 1[/tex]
Also given;
twice of A's share is less than 3 times than B's share by $20
[tex]2x= 3y -20\\2x-3y = -20 \ \ \ \ equation \ 2[/tex]
Solution:
Now multiplying equation 1 by 3 we get,
[tex]3x+3y=600 \ \ \ \ equation \ 3[/tex]
Now Adding equation 2 and equation 3 we get
[tex](2x-3y = -20)+ (3x+3y=600)\\5x=580\\\\x=\frac{580}{5}=\$116[/tex]
Now Substituting the value of x in equation 1 we get,
[tex]x+y=200\\116+y=200\\y=200-116 = \$84[/tex]
Hence, Share of A is $116 and Share of B is $84.

The community hall needs re-decorating
with new paint for the walls and ceiling,
and new tiles on the floor.
15 m
40 m
A 10 litre tin of paint covers
1 m2 floor tiles cost £3 each.
Work out the total cost of
to re-decorate the community hall.
Answer:
The total cost of to re-decorate the community hall is £2172.
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m wide and 3m high.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Are of Walls and Ceiling = [tex]2(l+b)h+lb=2(40+15)3+(40\times15)= 6\times55+600= 330+600 =930m^2[/tex]
Therefore, the area of walls and ceiling is 930 square meters.
Given: Cost for 10 litre of paint is £10 and 10 litre paint covers 25 square meter. Therefore,
Total Painting cost = [tex]10 \times \frac{930}{25} = \£372[/tex]
Therefore, the total painting cost of wall is £372.
Tiles will be required for floor. Let us find the area of floor.
Area of floor = [tex]l \times b = 40\times15 =600m^2[/tex]
Given: 1m squared floor tiles costs £3. So,
Total Cost for tiles = [tex]3\times600= \£1800[/tex]
Therefore, the total cost for tiles is £1800.
Now let us find total cost of to re-decorate the community hall;
Total Cost = the total painting cost of wall + the total cost for tiles = [tex]\£1800+\£372= \£2172[/tex]
Hence, the total cost of to re-decorate the community hall £2172.
To redecorate the community hall, the cost for tiling the floor will be £4500, and the cost for painting will depend on the price per tin, with a total of 93 tins needed to cover 930m².
Explanation:To calculate the total cost of re-decorating the community hall, we need to find the areas that need painting and tiling. Since the hall is a cuboid, the paintable area includes the four walls and the ceiling. The floor requires tiling.
The combined area of the four walls can be found by calculating the perimeter of the base, which is the sum of all sides ((2 × length) + (2 × width)), and then multiplying by the height. The ceiling is simply the length multiplied by the width.
Here is how to calculate the areas and costs:
Therefore, the cost for tiling the floor will be £4500, and the cost for painting will be 93 tins (if each tin is assumed to cost a certain amount, which is not specified in the question).
