Answer:
SA = 5645cm²Step-by-step explanation:
We have three pairs of congruent rectangles
9cm × 4m; 9cm × 5cm and 4m × 5cm
We know 1m = 100cm, therefore 4m = 400cm
The formula of an area of a rectangle l × w:
A = l · w
Substitute:
A₁ = 9cm · 4m = 9cm · 400cm = 3600cm²
A₂ = 9cm · 5cm = 45cm²
A₃ = 4m · 5cm = 400cm · 5cm = 2000cm²
Calculate the surface area:
SA = A₁ + A₂ + A₃
SA = 3600cm² + 45cm² + 2000cm² = 5645cm²
Answer:
202cm²
Step-by-step explanation:
2×(5×9)+2(4×5)+2(9×4)
90+40+72=202cm²

[tex](x + 20) + 3x + 60 = 180[/tex]
[tex]4x + 80 = 180[/tex]
Subtract sides 80
[tex]4x + 80 - 80 = 180 - 80[/tex]
[tex]4x = 100[/tex]

A- 17
B- 19
C-21
D-15
Answers
Answer:
Step-by-step explanation:
Step one:
give data
time= 8hours
distance=385mile
speed=?
Step two:
let us solve for the speed
Speed= distance/time
Speed=385/8
speed=48.125miles per hour
Step three:
let's find the time taken to cover 1000mile at the speed of 48.125 mi per hour
speed=distance/time
time=distance/speed
time=1000/48.125
time=20.779hours
approximately 21 hours

650 divided by 3/2 (With the full explanation)
Answers
Answer:
Multiply the numerator by the reciprocal of the denominator to get 650 x 2 divided by 3. Then, multiple 650 and 2 which is 1300, then it is 1300 over 3, or 433.3, and it is repeating.
Step-by-step explanation:
By the concept of division by a fraction, 650 divided by 3/2 will result in [tex]433 \frac{1}{3}[/tex].
We have to solve 650 divided by 3/2.
Mathematically, it can be expressed as:
650 ÷ [tex]\frac{3}{2}[/tex] -----(1)
To solve the above expression, at first we can apply the concept of dividing by a fraction. Which say that:
dividing by a fraction = multiplying by the reciprocal of the fraction
And the reciprocal of any fraction is simply the ratio of denominator and numerator.
So, the reciprocal of [tex]\frac{3}{2}[/tex] is [tex]\frac{2}{3}[/tex] .
Then, expression (1) will be equivalent to
[tex]650 \div \frac{3}{2} = 650 \times \frac{2}{3}[/tex] ------(2)
That means we have to multiply 650 and fraction 2/3.
To get the multiplication of two fractions, we multiply the numerators together and the denominators together.
[tex]650 \times \frac{2}{3} = \frac{650\times 2}{3}[/tex]
[tex]650 \times \frac{2}{3} = \frac{1300}{3}[/tex]
[tex]650 \times \frac{2}{3} = \frac{1300}{3}[/tex]
[tex]650 \times \frac{2}{3} = 433 \frac{1}{3}[/tex]
Thus, from equation (2)
[tex]650 \div \frac{3}{2} = 433 \frac{1}{3}[/tex]
Hence, 650 divided by 3/2 is:
[tex]650 \div \frac{3}{2} = 433 \frac{1}{3}[/tex]
