The length of the observable universe is.
880,000,000,000,000,000,000,000 kilometers across.
Imagine you work at NASA and must use this number in
calculations. Why might this befchallenging?
Answer:
Kindly check explanation
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 vendor of a coffee cart mixes coffee beans that cost $9 per pound with coffee beans that cost $5 per pound. How many pounds of each should be used to make a 75-pound blend that sells for $6.00 per pound
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
find the area of a rectangle flower garden that is 10 meters long and has a width that is half of its length.
show work pls
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
A box of cereal states that there are 72 calories in a 3/4 cup serving. What is the unit rate for calories per cup? How many calories are there in 3 cups of the cereal?
Answer: The unit rate for calories per cup = 96 calories
There are 288 calories in cups of the cereal.
Step-by-step explanation:
Given: Calories in [tex]\dfrac34[/tex]of cup = 72
Unit rate of calories per cup = [tex]\dfrac{72}{\dfrac34}=\dfrac{72\times4}{3}[/tex]
= 96
The unit rate for calories per cup = 96
Calories in 3 cups = 3 x (unit rate for calories)
= 3 x (96)
= 288 calories
Hence, there are 288 calories in cups of the cereal.

The owner of a small store buys coats for $55.00 each. Answer parts a and b. a. She sells the coats for $99.00 each. What percent of the purchase price is the sale price? b. The owner increases the sale price by the same percent that you found in part a when she buys jackets for $45 and sells them. How many jackets must the owner buy for the total jacket sales to be at least $390? Explain your answer.
Answer:
180% ; 5
Step-by-step explanation:
Purchase price per coat = 55
Sales price per coat = 99
% of purchase price is sales price :
X% * 55 = 99
(x / 100) * 55 = 99
0.01x * 55 = 99
0.55x = 99
x = 99 / 0.55
x = 180
180% of purchase price
B.)
180% * 45 = 81 per jacket
Number of jackets to sell to make atleast $390 in sales
$390 / $81 = 4.8
Hence, 5 jackets

Taiga wants to make a circular loop that she can twirl around her body for exercise. He will use a tube that is 2.5 meters long. Estimate the diameter of Taiga's exercise hoop? Round your answer to the nearest thousandth of a meter.
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
Angle= A Round your answer to the nearest hundredth.
The angle A using the sum of the angles in a right-angle triangle formula,
is = 44.5°
What is a right-angled triangle?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°
