Answer:
-9.1r + 3.9
Step-by-step explanation:
-6.2r - 4.6 -2.9r + 8.5
-6.2r and -2.9r are alike, so we combine.
-6.2r + -2.9r = -9.1r
-4.6 and 8.5 are alike, so we combine.
-4.6 + 8.5 = 3.9
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

Answer:
53 remainder 23
= 53 23/38
Step-by-step explanation:
Answer:
52 with 9 remaining
Step-by-step explanation:
When dividing this, we find that our whole number we are going to multiply with is 52, and if it was 53 it would be over 2,037. So, we multiply 39 by 52 and get 2,028, which is an extra of 9 remaining.

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]

A local theater charges $8 for adult tickets and $6 for children's tickets to a play. If a group of 24
goes to the theater and pays $164, how many of each ticket type did the group purchase?
Answer:
The theater was attended by 10 adults and 14 children.
Step-by-step explanation:
As the theater charges adults $ 8 and children $ 6 for each ticket, there is a surcharge of $ 2 for each adult. Thus, given that a group of 24 people attended the theater, as a minimum (that is, if they were all children) the establishment should charge $ 144 (6 x 24). Now, since it charges $ 164, there is a difference of $ 20 (164 - 144), attributable to the surcharge paid by adults for each ticket. Thus, since this surcharge is $ 2, dividing 20 by 2 we obtain 10, which is the number of adults who attended the theater.
This is verified by the following calculation:
10 x 8 = 80
14 x 6 = 84
80 + 84 = 164
Therefore, the theater was attended by 10 adults and 14 children.
9. If 15 men working 10 days earn $500. How much will 12 men earn working 14,
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.

20 POINTS PEOPLE!!!
it was estimated that 200 people would attend game night, but 196 people actually attended what is the percent error, to the nearest percent, of the estimate?
Subtract the two numbers to find the difference:
200-196 =4
Divide the difference by the estimated number:
4/200 = 0.02
Multiply by 100 to change to percent:
0.02 x 100 = 2%
The answer is 2%

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]

4 - 4(√3 - 4)iStep-by-step explanation:
Given
z₁ = 4 - 4√3iz₂ = -16iTo find
z₁ - z₂Solution
z₁ - z₂ =4 - 4√3i - (-16i) =4 - 4√3i + 16i =4 - 4(√3i - 4i) =4 - 4(√3 - 4)iCorrect option is C
Answer:
[tex]z1 = 4 - 4 \sqrt{3} i \\ z2 = - 16i \\ z1 - z2 = (4 - 4 \sqrt{3} i) - ( - 16i) \\ = 4 - 4 \sqrt{3} i + 16i \\ = \boxed{4 - 4( \sqrt{3} - 4)i}[/tex]

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.
