10. Insert three numbers between 24 and 44 to give five numbers in an arithmetic progression. Consider: a = 24 and 44 as the last term. Calculate the difference (d) to insert the three numbers.
Answer:
29,34,39
Step-by-step explanation:
t1=24
tn=t1+(n-1)d
t5=24+(5-1)d
t5=44
44-24=20
(5-1)*d=20
d=5
t5=24+5(5-1)=44
so sub it for 2,3,4
t2=24+5(2-1)=29
t3=24+5(3-1)=34
t4=24+5(4-1)=39

An ingot of metal shaped like the triangular prism below has a total mass of
25.6 kilograms. What is its density in grams per cubic centimeter.
Answer:
453
Step-by-step explanation:
9514 1404 393
Answer:
20 g/cm³
Step-by-step explanation:
The volume of the prism is the product of the area of its triangular base and its height. The triangle area is ...
A = 1/2bh
A = 1/2(16 cm)(8 cm) = 64 cm²
The height of the prism is 20 cm, so its volume is ...
V = Bh = (64 cm²)(20 cm) = 1280 cm³
The density of the ingot is the ratio of its mass to its volume.
ρ = M/V = (25,600 g)/(1280 cm³) = 20 g/cm³
The density of the ingot is 20 g/cm³.

write the equation of a line parallel to the line 2x-3y=6 that passes through (-4,-1)
Answer:
2x+3y=6 is -2/3
A line passing through 0,4 does have the same slope Because they are both parallel. Which is from a slope-intercept form. This is needed in an equation of a line.

The solution to 1568 × 184 - 1568 × 84 using suitable properties is; 156800
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
In conclusion, the solution is 156800

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.
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:

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

I purchased a piece of meat from the supermarket and the instructions on the
packaging said I should cook the meat for 20 minutes for each 550grams of weight.
The meat weight written on the outside of the packaging was 0.733kg. How long will
it take to cook the meat if I follow the instructions?
The time it would take to cook the meat if I follow the instruction is 26.65 minutes.
How long would it take to cook the meat?
The first step is to determine how long it would take to cook 1 gram of meat.
20 / 550 = 0.0364 minutes
Now convert kg to gram
0.733 x 1000 - 733 grams
Multiply, the answer gotten in the first step by 733
0.0364 x 733 = 26.65 grams
