Given data:

QP = PT and RP = SP

Let us first prove ΔQPR and ΔSPT are congruent.

In ΔQPR and ΔSPT,

QP ≅ TP (Given side)

∠QPR ≅ ∠ SPT (Vertically opposite angles are congruent)

RP ≅ SP (Given side)

Therefore, ΔQPR ≅ ΔSPT (by SAS congruence rule)

By corresponding parts of congruence triangles are congruence,

⇒ ∠Q ≅ ∠T

Hence ∠Q ≅ ∠T.

4z-3=9

4z=9+3

4z=12

z=12/4

Answer:

4z+2(square)2z=2(square)6

Step-by-step explanation:

4((z+3(z-1)))=36

4(z^2-z+3((z-3)))=36

4(z^2-z+3z-3)=36

4((z^2+(-z+3z)-3))=36

4(z^2+2z-3)=36

4z^2+8z-12=36

4z^2+8z=24

((4(square)z^2))+(square)8z=(square)24

Answer: The speed of the current is 1.5 km/h .

Step-by-step explanation:

Let x = speed of current and y = speed of canoe.

Since  , [tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]

As per given , we have

[tex]x+y=\dfrac{12}{2}\\\\ x+y=6......................(1)[/tex]

[tex]y-x=\dfrac{12}{4}\\ y-x=3...............(2)[/tex]

Adding (1) and (2) , we get

[tex]2y=9\\\Rightarrow\ y=\dfrac{9}{2}=4.5[/tex]

Put value of y in (1) , we get

[tex]x+4.5=6\\\Rightarrow\ x=1.5[/tex]

Hence, the speed of the current is 1.5 km/h .

To find the speed of the current, we can use the concept of relative velocity and set up equations for the downstream and upstream journeys.

In order to find the speed of the current, we can use the concept of relative velocity. Let's assume the speed of the canoeist in still water is 'v' km/h and the speed of the current is 'c' km/h.

Downstream journey: The effective speed of the canoeist is 'v + c' km/h. Given that the canoeist took 2 hours to travel 12 km downstream, we can set up the equation:

(v + c) * 2 = 12

Upstream journey: The effective speed of the canoeist is 'v - c' km/h. Given that the canoeist took 4 hours to travel 12 km upstream, we can set up the equation:

(v - c) * 4 = 12

Solving these two equations simultaneously will give us the values of 'v' and 'c', and the value of 'c' will represent the speed of the current.

"What is ..." is a pretty open question with lots of different answers that won't be helpful. If you're seeking a specific answer, it would be nice to see the question say what answer you seek.

Answer:

Step-by-step explanation:

as the temp t increases the number of cricket chirps also increases.

1: The complete table is according to the given function :

t  :    40   50   60   70   80   90   100

c :     10   50   90  130  170  210  250

2: It means when the temperature is 60 Fahrenheit then the number of cricket chirps is 90 per minute.

The given function is,

c = 4t - 180

Here t represents the temperature

c represents the cricket chirps per minutes

Now plug in each temperature value and solve for c:

When t = 40:

c = 4(40) - 150

c = 160 - 150

c = 10

When t = 50:

c = 4(50) - 150

c = 200 - 150

c = 50

When t = 60:

c = 4(60) - 150

c = 240 - 150

c = 90

When t = 70:

c = 4(70) - 150

c = 280 - 150

c = 130

When t = 80:

c = 4(80) - 150

c = 320 - 150

c = 170

When t = 90:

c = 4(90) - 150

c = 360 - 150

c = 210

When t = 100:

c = 4(100) - 150

c = 400 - 150

c = 250

Therefore, the complete table is:

t  :    40   50   60   70   80   90   100

c :     10   50   90  130  170  210  250

When the value of t is 60, the value of c is 90.

It means when the temperature is 60 Fahrenheit then the number of cricket chirps is 90 per minute.

The investment will be worth $4686.62 after 5 years.

Step-by-step explanation:

Principal, P = 3700

Rate, r = 4.75% = 0.0475

Number of years, t = 5 years

Number of times compounded, n = 5 times

Amount = P(1 + r/n)^nt

⇒ 3700 (1 + 0.0475/5)^25

⇒ 3700 (5.0475/5)^25

⇒ 3700 (1.0095)^25

⇒ 4686.62

Total cost of the chicken wings is $12.71

Step-by-step explanation:

⇒ Total Cost = 3.91 × 3.25

⇒ Total cost = $12.71

Final answer:

To find the total cost of chicken wings, add the weights of both packages (1.28 pounds + 2.63 pounds = 3.91 pounds) and multiply by the price per pound ($3.25), yielding a total cost of $12.71.

Explanation:

The problem provided describes a scenario where Raman buys two packages of chicken wings weighing 1.28 pounds and 2.63 pounds. To calculate the total cost of the chicken wings at a price of $3.25 per pound, first, we need to determine the total weight of the chicken wings by adding the weight of both packages together. Next, we multiply the combined weight by the price per pound.

Here is the step-by-step calculation:

Add the weights of the two packages: 1.28 pounds + 2.63 pounds = 3.91 pounds.

Multiply the total weight by the price per pound: 3.91 pounds *$3.25 per pound.

Calculate the overall cost: 3.91 * $3.25 = $12.71.

Therefore, the total cost of the chicken wings is $12.71.

To find the number of each type of shot, we can create a system of equations based on the given information and solve it. The equations are x + y = 56 and x + 2y = 95.

To solve this problem, we can create a system of equations based on the given information. Let's assume that the team made x 1-point shots and y 2-point shots. We know that the team made 56 successful shots in total, so the first equation is x + y = 56. We also know that the team scored 95 points in total, and since each 1-point shot contributes 1 point and each 2-point shot contributes 2 points, the second equation is x + 2y = 95.

Now we can solve this system of equations:

x + y = 56

x + 2y = 95

By solving these equations, we can find the values of x and y, which represent the number of 1-point and 2-point shots respectively.

#SPJ12

Team made 17 1-point shots and 39 2-point shots.

Let's define variables to set up the system of equations:

x: the number of 1-point shots

y: the number of 2-point shots

We know from the problem statement that:

The total number of shots is 56.

The total points scored is 95.

We can represent these conditions with the following system of equations:

Equation 1: x + y = 56

Equation 2: x + 2y = 95

Now, let's solve this system step-by-step:

Step 1: Solve Equation 1 for x:

x = 56 - y

Step 2: Substitute this expression into Equation 2:

56 - y + 2y = 95

Step 3: Simplify and solve for y:

56 + y = 95

y = 39

Step 4: Substitute y back into Equation 1 to find x:

x + 39 = 56

x = 17

Thus, the team made 17 1-point shots and 39 2-point shots.

I have bought 4 shirts and 6 pants.

Step-by-step explanation:

Let I have bought x number of shirts and y number of pants.

So, the two equation that we can write from the given conditions are

x + y = 10 ............. (1) and

24x + 32y = 288 ...... (2)

Now, solving equations (1) and (2) we get

24x + 32(10 - x) = 288

⇒ 8x = 320 - 288 = 32

⇒ x = 4

And y = (10 - 4) = 6

Therefore, I have bought 4 shirts and 6 pants. (Answer)

The number 77.31 x 10^4 in scientific notation is 7.731 x 10 ^ 5. To achieve this, the decimal place was moved to the left and the power of 10 increased accordingly.

To express the number 77.31 x 10^4 in scientific notation, we need to adjust it to fit the format 'a x 10^n', where 1 ≤ |a| < 10 and n is an integer. So, the main step is to transfer the decimal place in '77.31' to after the first digit, followed by multiplying by an appropriate power of 10.

Firstly, rewrite 77.31 as 7.731 by moving the decimal place one place to the left. Now, since our original number was multiplied by 10^4, this needs to be amended by 1 place for the movement of the decimal point. This results in 10^5, since you are now multiplying by 10 one more time than before.

Combining these, the given number is represented in scientific notation as 7.731 x 10 ^ 5.
