There are 2 rectangles. One was 1.2 cm by 3.4 cm. The other was measured 2.1 cm by 1.7 cm. How much is the perimeter?
Answer: See explanation
Step-by-step explanation:
Perimeter of a rectangle is given as:
= 2(length + breadth)
First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:
= 2(1.2+ 3.4)
= 2(4.6)
= 2 × 4.6
= 9.2cm
Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:
= 2(2.1 + 1.7)
= 2 × 3.8
= 7.6cm
Total perimeter = 9.2cm + 7.6cm = 16.8cm
7,650÷_________=7.65
Answer:
The answer is 58,522.5
Step-by-step explanation:
You multiply 7.65 by 7,650 and get 58,522.5. And when you plug it back in it’s correct.

Answer:
-4.65< -4 and 2/5
Step-by-step explanation:
To solve, this we can convert the fraction -4 and 2/5 into a decimal so that the values can be more easily compared. When we do this, we get the result that -4 and 2/5 equals -4.4. Now we can clearly see which value is greater because they are written in the same form:
-4.65<-4.4
-4.65<-4 2/5
Answer:
<
Step-by-step explanation:
You have to convert the mixed number by multiplying the whole number by the denominator, adding the numerator, and dividing the sum by the denominator.
4x5=20
20+2=22
22÷5=4.4
-4.65 < -4.40

Step-by-step explanation:
The price of a washing machine is reduced by 20% for a sale.
Afterwards, the sale price is increased by 30%.
Joachim says
The washing machine is now 10% more expensive than before the sale.
Explain Joachim’s error and work out the correct percentage change in the price of the washing machine from before the sale to after the sale
Answer:
1) Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The correct percentage change in price is 4%
Step-by-step explanation:
The price of the washing machine has the following parameters;
The percentage reduction of the price of the washing machine for a sale = 20%
The percentage by which the price is increased afterwards = 30%
Let 'x' represent the initial selling price of the washing machine before the price decrease, and let 'P' represent the sale price after the price increase, we have;
The price after the 20% reduction = x - 20% × x = x - (20/100) × x = 0.8·x
The price after the 30% increase after the sale = 0.8·x + 30% × 0.8·x = 0.8·x + 30/100 × 0.8×x = 0.8·x + 0.3 × 0.8·x = 1.04·x = x + 0.04·x = x + (4/100) × x = x + 4% × x
Therefore, Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The percentage change in the price after the sale is given as follows;
Price of the washing machine after the sale, P = 1.04·x = (104/100) × x = 104% × x
∴ P = 100%x + 4%x = (100/100)·x + 4%x = x + 4%
The percentage change in price = P - x = x + 4% - x = 4%
The correct percentage change in price = 4%

A triangle has side lengths of 21 cm and 17 cm. What is the range of values possible for the 3rd side?
Answer:
[tex]4 < x < 38[/tex]
Step-by-step explanation:
[tex]21 - 17 = 4[/tex]
[tex]21 + 17 = 38[/tex]
The range of 3rd side is in between 4 to 38.
[tex]4 < side 3 < 38[/tex]
A triangle has side lengths of 21 cm and 17 cm
side 1 = 21 cm
side 2 = 17 cm
What is the relation between side of triangle?
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore,
length of side 3
[tex]21-17 < side 3 < 21+17[/tex]
[tex]4 < side 3 < 38[/tex]
Therefore the range of 3rd side is in between 4 to 38.

After 14 years, I shall be three times as old as I was 4 years ago. What is my present age?
Answer:
Present age = 13 years
Step-by-step explanation:
Let the present age be x years.
14 years after age = (x + 14) years
4 years ago age = (x - 4)
According to the given information:
14 years after age = 3 times 4 years ago age
x + 14 = 3(x - 4)
x + 14 = 3x - 12
14 + 12 = 3x - x
26 = 2x
x = 26/2
x = 13 years
Thus, the present age is 13 years

Find the area of a trapezoidal tabletop, if its parallel sides are 2 m and 3 m long and the perpendicular distance
between them is l m.
Answer:
The area of the trapezoidal table top is 2.5 m²
Step-by-step explanation:
The area, A, of a trapezoid is given as half times the sum of the parallel side multiplied by the perpendicular distance between them
Therefore, we have;
[tex]A = \dfrac{a + b}{2} \times h[/tex]
The given parameters of the trapezoidal table top are;
The length of the parallel sides = 2 m and 3 m
The length of the perpendicular distance between the parallel sides = 1 m
Where, for the rectangular table top, we have;
'a', and 'b' = The lengths of the parallel sides = 2 m and 3 m respectively
h = The perpendicular distance between the parallel sides = 1 m
By substituting in the values, we have;
[tex]A = \dfrac{2 \ m + 3 \ m}{2} \times 1 \ m = 2.5 \ m^2[/tex]
The area of the trapezoidal table top, A = 2.5 m².
