Answer:

The height of water in the cylindrical vase is 6.2 cm.

Step-by-step explanation:

Volume of water in the measuring jug = 310 [tex]cm^{3}[/tex].

The radius of the cylindrical vase = 4 cm

volume of cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

But,

volume of water in the jug = volume of water in the vase = 310 [tex]cm^{3}[/tex]

So that,

310 = [tex]\frac{22}{7}[/tex] x [tex](4)^{2}[/tex] x h

     = [tex]\frac{22}{7}[/tex] x 16 x h

310 x 7 = 22 x 16 h

2170 = 352h

h = [tex]\frac{2170}{352}[/tex]

  = 6.163

h = 6.2 cm

The height of water in the cylindrical vase is 6.2 cm.

The height of water of the jug in cm is; 6.2 cm

We are given radius(r) = 4cm

V = πr²h

Thus;

310 = π × 4² × h

h = 310/(16π)

h = 6.167 cm

Approximating, we have; h = 6.2 cm

The angle A using the sum of the angles in a right-angle triangle formula,

is = 44.5°

According to the definition of a right triangle, if one of the triangle's angles is a right angle (90 degrees), the triangle is referred to as a right-angled triangle or just a right triangle.

A right triangle's initial characteristic is that one of its angles is 90 degrees. The biggest angle in a right triangle, the 90° angle is a right angle. The other two angles are either sharp or less than 90 degrees.

Now in the given question,

AB = 7

AC = 5

∠C = 90°

Using the formula Sin ∠B = 5/7

Simplifying it:

(Sin ∠B) = 5/7

⇒ [tex]Sin^{-1}[/tex] (Sin∠A) = [tex]Sin^{-1}[/tex] 5/7

⇒ ∠B ≈ 45.5°

Now we know ∠A + ∠B + ∠C = 180°

⇒ ∠A = 180° - 90° -45.5°

⇒ ∠A = 44.5°

Therefore, angle A in the triangle = 44.5°

Answer: 0.796 meters

Step-by-step explanation:

Circumference of circle = [tex]2\pi r[/tex] , where r=radius

Here, Circumference of loop = 2.5 meters

i.e. [tex]2\pi r=2.5[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\pi}[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m[/tex]

Diameter = 2r = 2(0.398) = 0.796 meters

Hence, The diameter of Taiga's exercise hoop = 0.796 meters

Step-by-step explanation:

Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.

For instance;

880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;

Answer:

Area is 50 meters squared

Step-by-step explanation:

So you know that length = 10 meters and width is half of the length.

You need to make an equation to solve for width, 'W', using length, 'L'

W = L / 2

Now just plug in length

W = 10 /2 = 5

Since you know length and width now, you can solve for area

Area = W * L

Area = 5 * 10

Area = 50

Answer:

56.25 pound of the coffee that costs $5 per pound is needed

18.75 pound of the coffee that costs $9 per pound is needed

Step-by-step explanation:

Let the number of pounds be x and y respectively

The total pounds is 75;

So;

x + y. = 75 •••••••(i)

Total cost of first type

9 * x = $9x

Total cost of second type;

5 * y= $5y

75 pound at $6 per pound; total cost of this is;

6 * 75 = $450

Thus;

9x + 5y = 450 ••••••••(ii)

From i, x = 75-y

Put this into ii

9(75-y) + 5y = 450

675 -9y + 5y = 450

4y = 675-450

4y = 225

y = 225/4

y = 56.25

x = 75 - y from i

x = 75-56.25

x = $18.75
