I need to find the value of x. Help please

Answer:

RS = 2[tex]\sqrt{7}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

RS² + RT² = TS² , that is

RS² + 6² = 8²

RS² + 36 = 64 ( subtract 36 from both sides )

RS² = 28 ( take the square root of both sides )

RS = [tex]\sqrt{28}[/tex] = [tex]\sqrt{4(7)}[/tex] = 2[tex]\sqrt{7}[/tex] ≈ 5.3 ( to 1 dec. place )

Answer:

(x - 10)(x + 10)

Step-by-step explanation:

x² - 100 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - 100

= x² - 10²

= (x - 10)(x + 10)

Answer:

326.56 square feet

Step-by-step explanation:

Surface area of a cylinder = 2πrh + 2πr²

Radius = Diameter/2

= 8 ft/2

= 4 ft

Height = 9 ft

Surface area of a cylinder = 2πrh + 2πr²

= (2 * 3.14 * 4 * 9) + (2 * 3.14 * 4²)

= 226.08 + 100.48

= 326.56 square feet

Surface area of a cylinder = 326.56 square feet

Answer:

Multiply the second equation by 3. The solution is x = 12, y = 10.

Step-by-step explanation:

The given equations are :

x+3y= 42 ....(1)

2x - y = 14 ...(2)

For elimination method,

Multiply the second equation by 3.

6x-3y=42 .....(3)

Adding equations (1) and (3).

x+3y+6x-3y=42+42

7x = 84

x = 12

Put the value of x in equation (1).

12+3y= 42

3y = 30

y = 10

So, x = 12 and y = 10. Hence, the correct option is (d).

Answer:

The total amount paid is $ 27.5.

Step-by-step explanation:

MAGALI BUY 15 CHOCOLATES AT $ 0.75 EACH ONE, AND 13 PACKAGES OF COOKIES AT $ 1.25 EACH, HOW MUCH SHOULD I PAY?

Number of chocolates = 15

Cost of a chocolate = $ 0.75

Packet of cookies = 13

cost of one packet of cookie = $ 1.25

The total amount paid is

= 15 x $ 0.75 + 13 x $ 1.25

= $ 11.25 + $ 16.25

= $ 27.5

Answer:

perimeter: 29 cm

Area: 49.5 cm^2

Step-by-step explanation:

perimeter is 9.5 + 6 + 7 + 6.5 = 29

Area: 7 * 6 = 42

9.5 - 7 = 2.5

2.5 * 6 = 15

15/2 = 7.5

42 + 7.5 = 49.5

Answer:

C: tan 60 = √3

Step-by-step explanation:

Let the adjacent part of the triangle be x and let the opposite side be y.

Thus, from trigonometric ratios;

x/10 = cos 60

We are given cos 60 = ½

Thus;

x/10 = ½

x = ½ × 10

x = 5

Similarly;

y/10 = sin 60

Now,from trigonometric relationship we know that; sin 60 = cos 30. Thus;

y/10 = cos 30

We are given cos 30 = (√3)/2

Thus;

y/10 = (√3)/2

y = 10 × (√3)/2

y = 5√3

Since it is a right angle triangle with one angle being 60°, it means the other one is 30° since sum of angles in a triangle is 180°.

Thus;

5/(5√3) = tan 30°

1/√3 = tan 30

Similarly;

5/10 = sin 60°

sin 60° = ½

Also;

tan 60 = (5√3)/5

tan 60 = √3

Also;

sin 30 = 5/10

sin 30 = ½

Looking at the options, the only correct one is Option C

Answer:

[tex]a_{n}[/tex] = 5n

Step-by-step explanation:

There is a common difference d between consecutive terms

d = 10 - 5 = 15 - 10 = 20 - 15 = 25 - 20 = 30 - 25 = 5

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 5 and d = 5 , then

[tex]a_{n}[/tex] = 5 + 5(n - 1) = 5 + 5n - 5 = 5n

Answer:

the graph of f(x) is {5 - (-2)) units, or 7 units, higher than that of g(x)

Step-by-step explanation:

The vertex form of a quadratic equation is y = a(x - h)^2 + k.  (h, k) represents the vertex.

Comparing the given f(x) = -3(x-1)^2 to the above general form, we see that h = 1 and k = 2.

Comparing the given g(x) = -3(x-1)^2 to the above general form, we see that h = 1 and k = -5.  

Thus, the x-coordinates of the vertex in both cases are the same:  1.  The y-coordinates differ:  for f(x), k = 2. and for g(x), k = -5.

Changing the k value translates the graph up or down.

In this case we see that the graph of f(x) is {5 - (-2)) units, or 7 units, higher than that of g(x).

L = 9

W = 4

H = 3

Formula

SA = 2*L*w + 2*L*H + 2 * H * W

Solution

SA = 2 * 9*4 + 2*9*3 + 2*3 * 4

SA = 72 + 54 + 24

SA = 150 in^2

Answer:

Angle 1: 145 degrees

Angle 2: 35 degrees

Angle 3: 145 degrees

Angle 4: 35 degrees

Angle 5: 145 degrees

Angle 6: 35 degrees

Angle 7: 145 degrees

Angle 8: 35 degrees

Step-by-step explanation:

1) See above.

2) Angles 4 and 2 are equal, because they are vertical angles (share a vertex) where two parallel lines are cut by a transversal (line c?)

Angles 1 and 2 equal 180 degrees when added together, so 180 - 35 = 145, which is the measure of angle 1.

Angles 1 and 3 are also vertical, and therefore equal.

When two or more lines are cut by a transversal, the angles that are in the same relative position are corresponding angles.

When the lines are parallel, the corresponding angles are congruent.

Congruent angles are equal. So Angle 1 = Angle 5 and Angle 2 = Angle 6. Then the rules for vertical angles apply again, giving you the measures for angles 7 and 8.

3) 1 and 3 are vertical, 2 and 4 are vertical, 5 and 7 are vertical, 6 and 8 are vertical.

1 and 5 are corresponding, 2 and 6 are corresponding, 3 and 7 are corresponding, 4 and 8 are corresponding.

4) 1 and 2, 3 and 4, 5 and 6, 7 and 8 are all supplementary pairs.

1 and 4, 2 and 3, 5 and 8, and 6 and 7 are supplementary pairs.

1 and 3, 2 and 4, 5 and 7, 6 and 8 are equal pairs because they are vertical.

1 and 5, 2 and 6, 3 and 7, 4 and 8 are equal pairs because they are corresponding.

Hopefully this covers all they wanted.

A drinking glass holds 0.3 litres correct to the nearest 0.1 litres

This means that, with 2 decimal places, the drinking glass holds between 0.25 litres and 0.34 litres.

-------------------------------------

Calculate the lower bound for the number of glasses of water which can be filled from the bottle

For the lower bound, we consider that 1 glass holds 0.25 litres, and want to find how many glasses are needed for 25 litres. So

1 glass - 0.25 litres

x glasses  - 25 litres

Applying cross multiplication:

[tex]0.25x = 25[/tex]

[tex]x = \frac{25}{0.25} = 100[/tex]

Thus, the lower bound for the number of glasses of water which can be filled from the bottle is 100.

Answer:

pulling force

Step-by-step explanation:

There is no special name for that.

Physics is usually just concerned with "forces", and doesn't specify whether the force pushes or pulls.

If you want to be more specific, you can just call it a "pulling force".

I hoped this was satisfying!
