1 answer:

Answer:

8 × 10¹

Step-by-step explanation:

don't panic. just breathe deeply and then think logically.

0.002 ... what is that ? 2 10ths ? 2 hundredths ? 2 thousandths ? 2 tenthousandths ?

the 3rd position after the decimal point is for 1/1000.

and that means 10^-3. in the same way as 1000 is 10³.

so, it is 2 × 10^-3.

the other rounded number is then 4 × 10⁴.

now, we are multiplying both numbers

2×10^-3 × 4×10⁴

what do we do ?

we combine the same types of factors, like the basic constants : 2×4 = 8

and 10^-3 × 10⁴.

what hairball when we multiply the same base number with exponents ? we add the exponents :

10^-3 × 10⁴ = 10¹ = 10

because -3 + 4 = 1

and so, the result is

8 × 10¹

WZ and XR are diameters what is thr measure of ZWX?
castortr0y [4]

Answer:

mZWX = 214°

Step-by-step explanation:

In a circle C, XR and WZ are two diameters.

∠ XCW = 34° and ∠ YCZ = 86°

We have to find the measure of arc ZWX

Since ∠XCW + ∠XCY + ∠YCZ = 180° [ angles on a straight line ]

34° + ∠XCY + 86° = 180°

120° + ∠XCY = 180°

∠XCY = 180 - 120 = 60°

Now arc ZWX = 360° - (∠XCY + ∠ YCZ)

                       = 360° - (60° + 86°)

                       = 360° - 146°

                       = 214°

Therefore answer is arc ZWX = 214°

How do you calculate the area and the perimeter of a parallelogram and a triangle?
Mnenie [13.5K]

for parallelograms:

area = b(h)

so basically, the length times the height. just like how you would find the area of a square.

perimeter: just add all of the sides together.

for triangles:

area = 1/2(b) x h

so half the length multiplied by the height. for example, if the length was 4, you have to use half of that. so that means 2 times whatever the height is.

perimeter: again, just add all three sides together
