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 ;

8.8 * 10^23 km

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:

60 miles

Step-by-step explanation:

Distance apart = 100

Rate of travel. :

Anthony = 12 mph

Cleopafda = 8 mph

Using the relation :

Speed = distance / time

Distance = speed * time

If they leave at the same time, travel time Can be represented as x

Anthony's distance + Cleopafda distance = total distance

12x +. 8x = 100

20x = 100

x = 5

Hence, they both traveled for 5 hours before meeting.

Distance covered by Anthony :

Speed * time

12 mph * 5h = 60 miles

Anthony must travel. For 60 miles.

Step-by-step explanation:

3.5 + 2.75 = 6.25

6.25/4.23 = 1.42 L

Approximately 1.48  liters of punch does this recipe make.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Missy makes punch for a party. She uses 3 1/2 cups of water, 2 3/4 cups of frozen pineapple juice.

∴ The total volume of the punch is ([tex]3\frac{1}{2} + 2\frac{3}{4}[/tex]) = 7/2 + 11/4 = (14 + 11)/4 = 25/4

cups of punch.

Now, 1 liter is 4.23 cups.

∴ 25/4 or 6.25 cups is (6.25/4.23) = 1.48 liters.

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

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:

To solve the equivalent fraction to 2/6, you divide or multiply the numerator and the denominator by thesame set for numbers. For example

2/6 = (2 × 3) / (6 × 3) = 6/18

2/6 = (2 ÷ 2) / (6 ÷ 2) = 1/3

The above fractions are both equivalent fractions of 2/6
