Answer:

0.28

Step-by-step explanation:

Because it is over 100 and there is two place values for the numerator just count two places to the left and add a decimal

Answer:

Step-by-step explanation:

use pythageran theorem

c=square root of a2+b2

but we are solving angle b

so

b2=c2-a2

b2=225-196

b2=29

b approximately = 5.39 Rounded up

Answer:

5.4

Step-by-step explanation:

c² = a² + b²

15² = 14² + b²

225 = 196 + b²

b² = 225 - 196

b² = 29

b = 5.4

Answer:

yes

Step-by-step explanation:

Use Pythagorean Theorem:

10² + 49.5² = 50.5² ??

100 + 2450.25 = 2550.25

2550.25 = 2500.25

Answer:

Step-by-step explanation:

answer is -3 because tan^2 theta-sec^2 theta means -1 and when u multiply -1 and 3 u will get -3.

A trigonometric expression is given to us and we need to simplify it and find out the value.

Given Expression :-

[tex]\sf\implies 3(tan^2\theta - sec^2\theta )[/tex]

Using Identity :-

[tex]\sf\implies sec^2\theta - tan^2\theta =1[/tex]

So that ,

[tex]\sf\implies tan^2\theta -sec^2\theta = -1[/tex]

Substitute the value :-

[tex]\sf\implies 3(tan^2\theta - sec^2\theta ) \\\\\sf\implies 3 *(-1) =\boxed{\red{\sf -3}}[/tex]

Hence the required answer is -3 .

Step-by-step explanation:

Step-by-step explanation:

Distance covered = speed × time.

Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.

This means distance covered while running would be

3.8 × 1/2 = 1.9 meters

Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be

1.6 × 1/2 = 0.8 meters

Total distance that Sasha covered while running and walking in 60 minutes would be

1.9 + 0.8 = 2.7 meters

Answer:

7/8 x 4/1

make 1/4 a reciprocal (basically just turning the fraction upside down)

then turn the division sign into a multiplication sign and multiply across:

7/8 x 4/1 = 28/8 = 3 4/8 = 3 1/2

From now on, remember that the smallest side in a triangle is always facing the smallest angle of the triangle.

_________________________________

The question told us that the shorter leg has a measure of 14 in which it is tha smallest side of the triangle thus 14 is the facing side to the 30 degrees angle .

As we know, in a right-angled triangle, the facing side to the angle of 30 degrees has half measure of hypotenuse. So :

1/2 × hypotenuse = 14

Multiply both sides by 2

hypotenuse = 28

Step-by-step explanation:

no parallelogram shown?

Answer:

2x - 4 + 2x

Step-by-step explanation:

4 ( x - 1 )

= 4 ( x ) - 4 ( 1 )

= 4x - 4

= 2x + 2x - 4

= 2x - 4 + 2x

Answer:

78.3 and 22

Step-by-step explanation:

Step-by-step explanation:

area of first triangle =1/2×112×202×sin30°

area of second circle=1/2×202×197×sin60.5°

Total area of estates=area of first triangle +area of second triangle

hope it helps.

Answer:

I think the answer is 244

Step-by-step explanation:

because I have learned that the total area is 360° so 360 - 116=244

Answer:

x ≈ 32°

Step-by-step explanation:

Using the Sine rule in the triangle

[tex]\frac{17}{sin116}[/tex] = [tex]\frac{10}{sinx}[/tex] ( cross- multiply )

17 × sinx° = 10 × sin116° ( divide both sides by 17 )

sinx° = [tex]\frac{10sin116}{17}[/tex] , then

x = [tex]sin^{-1}[/tex] ( [tex]\frac{10sin116}{17}[/tex] ) ≈ 32° ( to the nearest degree )

Answer:

Total wrapping paper need = 960.84 inch²

Step-by-step explanation:

Given:

Height of cylinder box = 8 inch

Radius of cylinder box = 9 inch

Find:

Total wrapping paper need

Computation:

Total wrapping paper need = Total surface area of cylinder

Total surface area of cylinder = 2πr(h + r)

Total wrapping paper need = 2[3.14][9][8+9]

Total wrapping paper need = 2[3.14][9][17]

Total wrapping paper need = [6.28][9][17]

Total wrapping paper need = [56.52][17]

Total wrapping paper need = 960.84 inch²

Answer:

B. h(x) = -3x + 4.

Step-by-step explanation:

I am assuming that the vertical shift is upwards,

A refection in the x axis gives -3x

Vertical shift upwards of 4 gives -3x + 4.

Answer:

n=12

Step-by-step explanation:

lol we meet again

just use the permutation formula for this one.

n!/(n-3)!=1320

[n×(n-1)×(n-2)×(n-3)!]/(n-3)!=1320

n(n-1)(n-2)=1320

(n²-n)(n-2)=1320

n³-3n²+2n-1320=0

n=12

Answer:

The area of the regular polygon is 17.5.

Step-by-step explanation:

To find the area of the regular polygon with a perimeter of 14 and radius of 2.5, the following calculation must be performed, knowing that the area of a regular polygon arises from multiplying the perimeter by the apothem divided by two:

(14 x 2.5) / 2 = X

35/2 = X

17.5 = X

Therefore, the area of the regular polygon is 17.5.

Step-by-step explanation:

BD = BC + CD = (7 + 17x)

BE = BA + AE = (8 + 13x)

By intersecting secants theorem:

[tex] BC\times BD = BA\times BE[/tex]

[tex] 7(7+17x) = 8(8+13x)[/tex]

[tex] 49+119x = 64+104x[/tex]

[tex]119x -104x = 64-49[/tex]

[tex]15x = 15[/tex]

[tex]x = \frac{15}{15}[/tex]

[tex]x =1[/tex]

Answer: Volume is 64 m³

Step-by-step explanation: In cubical box all sides have equal length.

Lets mark length of side a. So base is a square which area is a² = 16 m²2² and

lenght of a = √(16 m²) = 4 m . Volume of cube is a³

Answer:

150 of Grant`s coins are quarters. i hope this helped

Answer:

I believe it's C

Step-by-step explanation:

The surface area of the bottom is 64 because it's 8 times 8.

All of the sides are 8 times 12.

8 times 12 is 96.

96 times 4 (for all four sides) is 384.

So the sides (384) plus the bottom (64) is 448, or C
