Step-by-step explanation:

6.212 x 10^8 = 621,200,000

4.73  x 10^9 = 4,730,000,000

Answer:

m<H = 62°

Step-by-step explanation:

If FG is congruent to HF, it means their opposite angles are also congruent to each other. This implies that, <H = <G. Thus, ∆FGH is an isosceles triangle with base angles <F and <G.

Given that m<F = 56°, therefore:

56° + 2(m<H) = 180° (sum of triangle)

2(m<H) = 180° - 56°

2(m<H) = 124°

m<H = 124/2

m<H = 62°

Answer:

x = 128

Step-by-step explanation:

Right angles are 90 degrees.  90 + 90 + 52 = 232. 360 (angles in a quadrilateral) - 232 = 128.

Answer:

ans is 128

Step-by-step explanation:

90+90+52+x=360(all sides of triangle is 360)

180+52+x=360

232+x=360

x=360_232

x=128

Answer:

LQ: 7.5

UQ: 21

Step-by-step explanation:

After identifying the median, remove it and split the data into two halves.

The upper quartile is the median is the top set of data and the lower quartile is the median is the bottom set of data.

If you have two numbers in the middle, you add them and divide by two to find the median/ quartile

so

[tex]\frac{7+8}{2} =7.5[/tex]

[tex]\frac{21+21}{2} =21[/tex]

Answer:

310 in²

Step-by-step explanation:

Area of the figure = area of the larger rectangle + area of the medium rectangle + area of smaller rectangle

✔️Area of the larger rectangle = L*W

L = 20 in

W = 7 in

Area = 20*7 = 140 in²

✔️Area of the medium rectangle = L*W

L = 20 - 2 = 18 in

W = 22 - (10 + 7) = 5 in

Area = 18*5 = 90 in²

✔️Area of the smaller rectangle = L*W

L = 8 in

W = 10 in

Area = 8*10 = 80 in²

✅Area of the figure = 140 + 90 + 80 = 310 in²

Answer:

The number is 4

Step-by-step explanation:

Let the number  = 'x'

Reciprocal of 'x' = 1/x

Reciprocal of 2 = 1/2

8 times the reciprocal of 'x' = [tex]8*\frac{1}{x}\\[/tex]

[tex]8*\frac{1}{x}= 4* \frac{1}{2}\\\\8*\frac{1}{x}= 2\\[/tex]

Now multiply both sides by x

[tex]8*\frac{1}{x}*x = 2*x\\\\8 = 2x[/tex]

Now divide both sides by 2

[tex]\frac{8}{2}=\frac{2x}{2}\\\\4 = x[/tex]

x = 4

Answer:

4/12

Step-by-step explanation:

1/3=x/12

using the butterfly method you see that

12=3x

and when solved you get

x=4

giving you

4/12

Also multiply 1/3 by 4 on each side

One third is equivalent to 4 over 12.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Let the unknown number be x.

Here, 1/3 = x/12

Multiply both the numerator and denominator of 1/3 by 4, we get

4/12

So, 4/12 = x/12

x=12

Therefore, the unknown number is 12.
