Answer:
5 and 3Step-by-step explanation:
Let the numbers be x and y.
The equations are:
x - y = 22x + y = 13Add up the equations to eliminate y and solve for x:
x - y + 2x + y = 2 + 133x = 15x = 15/3x = 5Now find the value of y:
y = x - 2 y = 5 - 2 y = 3Let the numbers be a and b
a-b=2--(1)2a+b=13---(2)Adding both
[tex]\\ \sf\longmapsto 3a=15[/tex]
[tex]\\ \sf\longmapsto a=5[/tex]
Putting in eq(1)
[tex]\\ \sf\longmapsto 5-b=2[/tex]
[tex]\\ \sf\longmapsto b=5-2[/tex]
[tex]\\ \sf\longmapsto b=3[/tex]
58,300 meters to kilometers. Round to the appropriate number of significant digits.
Answer:
58.3km
Step-by-step explanation:
58300 ÷ 1000 = 58.3km
Given:-
58,300 metres
Converting to kilometers, let's do by:-
[tex] \frac{58300 \: m}{1} \times \frac{1}{1000} km[/tex]
[tex] \frac{58300}{1000} [/tex]
[tex] => 58.3 \: km[/tex]
Therefore, in kilometers, 58300 m = 58.3 km.

a scale drawing of Lafayette square is 8 inches long and 4 inches wide. The actual park is 160 feet wide. What is the actual area of the park, in square yards?
Answer:
Lafayette Square is about 5688.89 square yards
Step-by-step explanation:
The scale factor( ratio between the two sides) is 8 inches long to 4 inches wide or 2 to 1; 2 inches to one 1
Given the actual park is 160 feet wide ( need this measurement in inches).
so the actual part is 160 · 12 = 1920 inches wide.
Using the ratio long/ wide = long/ wide 2/1 = ?/1920. The part is 3840 inches long.
Answer need to be in yards: divide by 36 because 36 inches = 1 yard.
Long = 3840/36 = 320/3 yards
wide = 1920/36 = 160/3 yards
Actual area = L · W
= (320/3)·(160/3)
= 51200/9
= 5688.89 square yards

Answer:
I think the answer is 25
Step-by-step explanation:
You've poured some 8% (by mass) alcohol solution and some 12% alcohol solution into a large glass mixing container. Now you have 760
grams of 10% alcohol solution. How many grams of 8% solution and how many grams of 12% solution did you pour into the mixing container?
Step-by-step explanation:
you mixed an 8% and a 12% solution together.
so, you get (8%×mass1 + 12%×mass2)/((mass1 + mass2)/2) as resulting % of the combined solution.
since the result is 10%, which is precisely the arithmetic middle
(8 + 12)/2
we see that mass1 = mass2.
in other words : the same quantity (mass) of the 8% solution and the 12% solution was mixed together.
so, 760g = 2×mass
=>
mass = 380g
380g of the 8% solution and 380g of the 12% solution were mixed together.

Distributive PropertiesWe want to solve;
1568 × 184 - 1568 × 84
Now, to solve this, we need to understand distributive property which is;
a(b + c) = ab + ac
Thus, applying distributive property to our question, we will have;
1568(184 - 84)
>> 1568(100)
>> 156800

Answer:
20 inches
Step-by-step explanation:
When the instructions say a triangle is similar, it basically means they are exactly the same unless otherwise specified.
With this, we just need to find the ratio.
We can see that DE is 6 inches while AB is 18 inches.
This means that the ratio between DEC and ABC is 1:3, respectively.
So if AC is 30, that means DC should be 10.
All we have to do now is subtract DC from AC to find AD
30 - 10 = 20
So AD is 20 inches
I'm pretty sure there is a more mathematical approach to this but this is good enough to solve any problem like this.
Answer:
20 inches
Step-by-step explanation:
Set up a proportion
BA/AC = ED/DC
You are given that BA = 18, AC = 30, ED = 6
18/30=6/
18/6 = 3
30/3 = 10 = DC
Sense DC = 10
AC-DC
30-10=20

A scuba diver descends in the water at a rate of 20 1/2 feet per minute for 2.8 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 25 feet per minute for 2 minutes. What is the scuba diver's position relative to sea level after the 4.8 minutes?
Answer:
7.4 feet below sea levelStep-by-step explanation:
Assumed the starting point is the sea level 0.
After 2.8 min the diver is at position:
20 1/2 * 2.8 = 20.5 * 2.8 = 57.4 feet below sea levelThe position change after next 2 minutes:
25*2 = 50 feetThe position of the diver after 4.8 min:
57.4 - 50 = 7.4 feet below sea levelAnswer:
