days? [Ans. $560]
7
Answer:
Firstly need to understand the questions.
If 15 men working 10 days, They earn 500.
If 12 men working 14 days, how much they will earn?
Step-by-step explanation:
560
Solution:
15 men working for 10 days =500
1 man working for 1 day = 500/(10*15) =10/3
Now 12 men working for 14 days = 12*14*10/3 =560.
I am pretty sure that answer is right.

The quantity r varies jointly with t and u and inversely with s when t= -12, u= -7, and s= -4, r= -126. Find r when t= -8, u= 8, and s= -6.
Write your answer in exact form.
Answer:
r = 64
Step-by-step explanation:
r = (k*t*u)/s
Where,
k = constant of proportionality
t = -12,
u= -7,
s= -4,
r= -126.
r = (k*t*u)/s
-126 = (k*-12*-7)/-4
-126 * -4 = 84k
504 = 84k
k = 504/84
k = 6
Find r when t= -8, u= 8, and s= -6.
r = (k*t*u)/s
= (6*-8*8) / -6
= -384 / -6
= 64
r = 64

Using scientific notation, what is the solution to (5.4 * 105) - (1.2 * 103)?
5.412 * 105
5.388 * 102
5.388 * 103
5.388 * 105
Answer:
[tex]5.4*10^{5}-1.2*10^{3}=5.388*10^{5}[/tex]
Step-by-step explanation:
We can rewrite [tex]1.2*10^{3}[/tex] as [tex]0.012*10^{5}[/tex].
Now, let's subtract each term:
[tex]5.4*10^{5}-0.012*10^{5}[/tex]
we can take a common factor.
[tex](5.4-0.012)*10^{5}=5.388*10^{5}[/tex]
Therefore the answer is [tex]5.388*10^{5}[/tex].

A drop of oil makes a circular ring in a water puddle. The radius of the oil ring expands at 1.5 cm per second. If r(t)=1.5t and a(r)=лr^2, what composition of function describes the area of the oil ring in terms of time?
Answer:
[tex]a(t) =n(0.25t^2)[/tex]
Step-by-step explanation:
Given
[tex]r(t) = 0.5t[/tex]
[tex]a(r) = nr^2[/tex]
Required
Determine the area in terms of time
From the question, we have:
[tex]r(t) = 0.5t[/tex] -> radius per time
and
[tex]a(r) = nr^2[/tex] --> area from radius
The interpretation of the question is to find the composite function: a(t)
If [tex]a(r) = nr^2[/tex], and [tex]r(t) = 0.5t[/tex], the
Substitute 0.5t for r
[tex]a(t) =n(0.5t)^2[/tex]
[tex]a(t) =n*0.25t^2[/tex]
[tex]a(t) =n(0.25t^2)[/tex]

Jim is older then Kelsey.The sun of their ages is 88 and the difference of their ages is 30. Write a system of equations to represent this situation.how old is Jim? How old is Kelsey?
Answer: System of equations •y+x=88 •y-x=30
Step-by-step explanation: Let x represent Jim and y represent Kelsey.
1. The problem says the sum of their ages is 88 in order to get 88 you would have to add x (Jim) and y (Kelsey) together. By doing this you would get y+x=88
2. The problem says that the difference of their ages is 30. In order to get 30 you would subtract x (Jim) from y (Kelsey) By doing this you would get y-x=30

The pair of triangles that are congruent by the ASA criterion is
The pair of triangles that are congruent by the SAS criterion is
___________________________________________________________
Answer:
The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ.
The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.
___________________________________________________________
___________________________________________________________
Step-by-step explanation:
Two triangles are congruent by ASA property if any two angles and their included side are equal in both triangles .In triangles Δ ABC and Δ XYZ the equal side 5 is between the two equal angles. So these triangles are congruent by ASA criterion.
Two triangles are congruent by SAS if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle .In triangles Δ BAC and ΔRQP. the included angles A and Q are equal and hence the triangles are congruent by SAS criterion.
___________________________________________________________
The solution is:
The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ.
The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
Two triangles are congruent by ASA property if any two angles and their included side are equal in both triangles .In triangles Δ ABC and Δ XYZ the equal side 5 is between the two equal angles. So these triangles are congruent by ASA criterion.
so, we have,
Two triangles are congruent by SAS if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle .In triangles Δ BAC and ΔRQP. the included angles A and Q are equal and hence the triangles are congruent by SAS criterion.
Hence, The solution is:
The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ.
The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.

Brainliest pls
Answer:
7
Step-by-step explanation:
5.1g = 35.7
g is being multiplied by 5.1. The opposite operation to multiplication is division. To get rid of the 5.1 multiplying g, we need to divide 5.1g by 5.1 since 5.1/5.1 = 1. The rule of equations is that you must do the same operation to both sides of the equation. Since we need to divide the left side by 5.1, we divide both sides by 5.1.
5.1g/5.1 = 35.7/5.1
g = 7

(4+5=)9
divide 18 by the denominator 9 and get
-9x-2
/1
since anything pretty much divided by 1 remains the same this is simplified to
-9x-2 and since you dont know x's variable this is its simplifed form
Answer:
-9x-2
Step-by-step explanation:
[tex]9x(-1)-18/(4+5)[/tex]
Multiply 9x and -1
[tex]-9x-18/(4+5)[/tex]
Add 4 and 5
[tex]-9x-18/9[/tex]
Divide 18 and 9
