Answer:

P of rectangle = 2(L + W)

21 units = 2(n units + W)

21 units = 2nunits + 2W

21 = 2n + 2W

2W = 21 - 2n

W = 21 - 2n units.

Step-1 : Multiply the coefficient of the first term by the constant   1 • 7 = 7  

Step-2 : Find two factors of  7  whose sum equals the coefficient of the middle term, which is   -8 .

     -7    +    -1    =    -8    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  -1

Jerry deposited 20,000 on an investment that will give 1,750 for every year that his money stays in the account. How much money will he have in his account by the end of the year 8? with solutions​

Answers

Answer:

$34,000

Step-by-step explanation:

Jerry will get $1,750 for every year that his money stays in the account thus for 8 years he will get:

8*1,750 = $14,000

Together with the deposited money:

$20,000 + $14,000 = $34,000

By the end of year 8 there will be $34,000 of Jerry's account.

Answer:

∠ C ≈ 22.6°

Step-by-step explanation:

Since Δ ABC is right at B

Using the sine ratio in the right triangle

sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{5}{13}[/tex] , then

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)

Answers

Answer:

x = + 14.88 km

Step-by-step explanation:

Let's solve for x using the Pythagorean Theorem.  

The length of the hypotenuse is 15.8 km; that of the shorter leg is 5.3 km.

Since a² + b² = c², we get:

(5.3 km)² + x² = (15.8 km)²

Solving for x², we obtain (15.8 km)² - (5.3 km)² = 249.64 km² - 28.09 km²

The last expression returns the value 221.55 km² for x²

Taking the square root of both sides, we get x = + 14.88 km

>> Answer

___________

[tex] \: [/tex]

[tex]\boxed{ \rm{answer \: by \: { \boxed{ \rm{☆HayabusaBrainly}}}}}[/tex]

Step by step :

x² = (15,8)² - (5,3)²

x² = 249,64 - 28,09

x² = 221,55

x = 14,88km

Multiply 6 and 4 to get 24.

−102+7k+24−14−464−14k

Answers

The correct statements about the scenario are;

The function is an arithmetic sequenceThe number 2 is the number of tables added when t increases by 1.The number 4 represents the number of people that can be seated at an event if only 1 table is available.

According to the function given;

p(t)=4+2(t−1)

Evidently, the function, p(t) represents the number of people that can sit when t tables are available.

T(n) = a + d(n -1)

In essence, the function resembles that of a general arithmetic progression with first term, a = 4.

The common difference, d = 2.

The statements which are correct are therefore as listed above.

What is the iterative rule for the following sequence?

A.) an=4•(1/5)^n-1
B.) an=4•(1/5)^n
C.) an=1/5•4^n-1
D.) an=1/5•4^n

Answers

Answer:

A.) 4 * (1/5)^(n-1)

Step-by-step explanation:

a1 = 4 * (1/5)^(1-1) = 4* (1/5)^0 = 4*1 = 4

a2 = 4 * (1/5)^(2-1) = 4 * (1/5)^1 = 4 * 1/5 = 4/5

a3 = 4 * (1/5)^(3-1) = 4 * (1/5)^2 = 4 * 1/25 = 4/25

a4 = 4 * (1/5)^(4-1) = 4 * (1/5)^3 = 4 * 1/125 = 4/125

a5 = 4 * (1/5)^(5-1) = 4 * (1/5)^4 = 4 * 1/625 = 4/625

Answers

For the expression 7 - i ohms, the conjugate will be 7 + i ohms (the sign was changed from negative to positive)

The impedance of the circuit is written in form of a complex number.

The standard representation of a complex number is expressed as a + ib where:

a is the real part

ib is the imaginary part

The conjugate of the complex number a + ib will be a - ib. Note that the signs of the expression were changed from addition to subtraction.

Mateo jogs for 3 3/4 miles on Saturday and 4 2/5 miles on Sunday. What is the total distance, in miles, that Mateo jogged in the past 2 days?

Answers

Answer:

Mateo jogged 8 3/20 miles in the past 2 days.

Step-by-step explanation:

Given:-

Distance on Saturday = 3 3/4

Distance on Sunday = 4 2/5

Total distance = 3 3/4 + 4 2/5

                       = 15/4 + 22/5

                       = LCM of deniminators (20)

                       = 75/20 + 88/20

                       = (75 + 88)/20

                      =  163/20

                      = 8 3/20

Answer:8+ (3/20)

Step-by-step explanation: We will assume that "today" is a Monday.
