For this question, we must use BIDMAS
Brackets
Indices
Division
Multiplication
Addition
Subtraction
26.6 x 24.4 / 5.67 x 4.02
First, round all the values to their first significant figure
30 x 20 / 6 x 4
The first occurring operation in BIDMAS is Division
20/6 = 3 1/3
Now do the multiplication
30 x 3 1/3 x 4 = 400
Or you can round to the nearest whole number (although it can be more difficult if doing sums in your head)
27 x 24 / 6 x 4
27 x 4 x 4
27 x 16 = 432
The more accurately you round, the closer the estimation is to the actual answer (≈460)
1 Sig Fig = 400
Whole number = 432
Answer:
Wouldn't it be 2 because of 14÷7?
Ok so basically L=5+w
w=w
P=38
and A=?
well we know that P=all the four sides added so
38=2(5+w)+2w
38=10+2w+2w
38=10+4w
28=4w
w=7
so if L=w+5 then L=7+5 so L=12
A=LxW so A=12x7 A=84
Answer:
<u> The distance between opposite corners of the windowpane is 8.5 inches (rounding to the nearest tenth).</u>
Step-by-step explanation:
1. Let's use the Pythagorean Theorem to find the distance between opposite corners of the windowpane:
With the information given, we have a right triangle with the distance between opposite corners of the windowpane as the hypotenuse and its sides of 6 inches as the width and length of the windowpane and as sides of the right triangle.
Distance between opposite corners of the windowpane ² = Width of the windowpane ² + Length of the windowpane ²
Replacing with the real values:
Distance between opposite corners of the windowpane ² = 6² + 6²
Distance between opposite corners of the windowpane ² = 36 + 36
Distance between opposite corners of the windowpane ² = 72
√ Distance between opposite corners of the windowpane² = √72
<u> Distance between opposite corners of the windowpane = 8.5 inches (rounding to the nearest tenth)</u>
Answer:
x = 71°
Step-by-step explanation:
Segments of tangents from the same external point are congruent, that is
AT = BT
Then Δ ABT is isosceles with base angles congruent , so
x = 
= 
= 71°
