The diagram shows a solid metal cuboid.
The areas of three of the faces are marked on
the diagram.
The lengths, in cm, of the edges of the cuboid
are whole numbers.
The metal cuboid is melted and made into cubes.
Each of the cubes has sides of length 2.5 cm.
Work out the greatest number of these cubes that can be made.
You must show your working.
Answer:
6 cubes
Step-by-step explanation:
Considering the given cuboid, it can be deduced that;
length of the cuboid = 7 cm
width of the cuboid = 3 cm
height of the cuboid = 5 cm
Thus,
volume of the cuboid = length x width x height
= 7 x 3 x 5
= 105 cubic centimetres
The cubes has sides of length 2.5 cm.
volume of each cube = length x width x height
= 2.5 x 2.5 x 2.5
= 15.625 cubic centimetres
The greatest number of cubes that can be made = [tex]\frac{105}{15.625}[/tex]
= 6.72
The greatest number of cubes that can be made from the cuboid is 6.

Answer:
The second option is correct.
Step-by-step explanation:
If x = 5, then this happens.
1(5) - 2 < 3
5 - 2 < 3
3 < 3
That is incorrect because 3 = 3.
The second option is correct, because:
4 - 2 < 3
2 < 3
This work so the second option is correct

The picture shows the letter H that is on a store sign.
3 in.
9 in.
3 in.
3 in.
3 in.
3 in.
What is the area of this letter H? Enter the answer in the box.
square inches
Answer:
[tex]63in^2[/tex]
Step-by-step explanation:
To find the area of the larger, complex figure, divide the shape up into smaller figures, solve for the area of each smaller part and then add up the answers to find the total area. The figure can be divided into two rectangles and a square.
The two rectangles are congruent, their dimensions are the following,
9in x 3in
The area of the square is the following,
3in x 3in
To find the area of both of these figures, one uses the formula,
[tex](length)(width)[/tex]
Substitute in each dimension and solve for the total area by adding up the results,
[tex]((9)(3))+((9)(3))+((3)(3))\\\\=(27)+(27)+(9)\\\\= 63[/tex]

question
(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!
Answer:
(60-5.8) ÷ 5 - 3² = 1.84 (approx)
Step-by-step explanation:
(60-5.8) ÷ 5 - 3²
First simplify the numbers inside the bracket.
(60-5.8) = 54.2
Now, the equation is in the form of,
54.2 ÷ 5 - 9
Put 54.2 ÷ 5 in a bracket for easy calculation.
(54.2 ÷ 5) - 9
Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84
Subtract 9 from 10.84
10.84 - 9
You will now get the answer as,
1.84 (approx)

Rewrite and simplify. 64-3/4
Answer:
64 - .75
64 - .75 = 63.25
have a good day/night
Answer: 63.25 (Decimal) or 63 1/4 (fraction)
Step-by-step explanation: 64 - 3/4. 3/4 is 0.75 in decimal form, so subtracting it would be 63.25 which would be 63 1/4 in fraction form. I don’t think you can simplify it since 1/4 is already at it’s smallest form.
A perfect square is the product of any positive whole number used as a factor exactly two times. [Example: 49 is a perfect square because 7 × 7 = 49] The positive whole number N, when multiplied by 150, is a perfect square. What is the least possible positive whole number value for the number N?
Jasmine invests £250 in a building society. After the first year her account
contains £262.50. After the second year it contains £280.88. Calculate the
percentage increase of the amount in her account:
(a) during the first year.
(b) during the second year.
(c) over the two years.
Give your ansivers correct to 2 decimal places
Answer:
(a) 5.00%
(b) 7.00%
(c) 12.35%
Step-by-step explanation:
(a) Find the difference, in £, between the value after the first year and the original value. Divide that by the original value and multiply by 100:
[tex]262.50-250=12.50\\\\\frac{12.5}{250}*100= \frac{125}{25}=5.00\%[/tex]
(b) Find the difference, in £, between the value after the second year and the value after the first year. Divide that by the value after the first year and multiply by 100:
[tex]280.88-262.50=18.38\\\\\frac{18.38}{262.50}*100= 7.0019\%=7.00\%[/tex]
(c) Find the difference, in £, between the value after the second year and the original value. Divide that by the original and multiply by 100:
[tex]280.88-250=30.88\\\\\frac{30.88}{250}*100= 12.352\%=12.35\%[/tex]
