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:

Step-by-step explanation:

The solution to the inequalities is (-11/15. 38/15)

Given the systen of inequalities expressed as:

In order to get the graph that shows the solution and the coordinate of the solution, equate the inequalities to havee:

(5-x)/5 = 2x + 4

5 - x = 10x + 20

20 - 5 = -11x

15 = -11x

x = -11/15

Given that y = 2x + 4

y = -22/15 + 4

y = 38/15

The solution to the inequalities is (-11/15. 38/15)

Answer:

  x = 21

Step-by-step explanation:

The parallel lines divide the segments proportionally.

  x/27 = 28/36

  x = 27(28/36) . . . . multiply by 27 (in your head: (3·9)(4·7)/(4·9) = 3·7)

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].

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]

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.

Thank you :)

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.

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.

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.

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:

a. How many employees accumulated less than 3,000 miles?

The number of employees accumulated less than 3,000 miles= 5

So the number of employees accumulated less than 3,000 miles is 5.

d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?

8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.

Step-by-step explanation:

The given frequency distribution representing the number of frequent flier miles accumulated by the employees in a company.                        

Frequent Flier Miles (000) Frequency

0                     up to 3 5

3                      up to 6 12

6                      up to 9 23

9                     up to 12 8

12                   up to 15 2

Total                       50

a. How many employees accumulated less than 3,000 miles?

The number of employees accumulated less than 3,000 miles= 5

So the number of employees accumulated less than 3,000 miles is 5.

b. Convert the frequency distribution to a cumulative frequency distribution.

We make the cumulative frequency distribution from the frequency distribution by adding up a frequency and all other frequencies below it.                

Frequent Flier Miles Frequency Cumulative frequency

0 up to 3                                5 5

3 up to 6                                      12 17

6 up to 9                                      23 40

9 up to 12                               8 48

12 up to 15                               2 50

Total 50

d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?

8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.

Answer:

−7r^(2)+12r+10x−18

Step-by-step explanation:

Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r

For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r

Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)

Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18
