Answer: P = 19,571.42857142857

Step-by-step explanation:

Plug in the variables.

5480 = x(.04)(7)

.04*7=.28

5480=.28x

.28x/.28=x

5480/.28=19,571.42857142857

19,571.42857142857(.04)(7)=5480

P = 19,571.42857142857

Answer:

19571.43

Step-by-step explanation:

We are asked to solve for P using formula $I=Prt$ , when $I=5480; r=0.04\text{ and }t=7$ .

Upon substituting our given values in simple interest formula, we will get:

$5480=P*0.04*7$

$5480=P*0.28$

Switch sides:

$P*0.28=5480$

Now, we will divide both sides of our given equation by 0.28 as:

$\frac{P*0.28}{0.28}=\frac{5480}{0.28}$

$P=19571.42857$

$P\approx 19571.43$

Therefore, the principal amount (P) is approximately 19571.43.

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.

Margaret [11]

Answer:

The correct option is 3.

Step-by-step explanation:

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.

J = 90°, J' = 90°

K = 65°, K' = 65°

L = 25°, L' = 25°

In a rigid transformation the image and pre-image are congruent. Reflection, translation and rotation are rigid transformation.

In a non rigid transformation the image and pre-image are similar. Dilation is a non rigid transformation.

In a rigid or a nonrigid transformation, the corresponding angles are same. If the corresponding sides are same, then it is a rigid transformation and if the corresponding sides are proportional, then it is a non rigid transformation.

It can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures.

Therefore option 3 is correct.

Our new training room can seat 150 employees. If 6 tables consisting of 6 chairs are now taken, what percentage of our new facil

Anvisha [2.4K]

Step 1

Find out how many chairs are already taken. Multiply the tables by the chairs

$6*6=36$

Step 2

By using proportion find the percentage

$\frac{150}{100} =\frac{36}{x} \\ \\ 150*x=36*100\\\\ x= \frac{3600}{150} \\ \\ x=24$

therefore

the answer is

$24$ %

Solve the radical equation. square root 6n-11= n – 3 Which solution is extraneous? A.)2

Anvisha [2.4K]

ANSWER

D) 10

EXPLANATION

We want to solve the radical equation,

$\sqrt{6n - 11} = n - 3$

Square both sides,

$6n - 11 = (n - 3) ^{2}$

Expand brackets on right hand side,

$6n - 11 = {n}^{2} - 6n + 9$

Rewrite in general quadratic equation form,

${n}^{2} - 12n + 20 = 0$

Factor to obtain,

$(n - 2)(n - 10) = 0$

Apply the zero product principle to get,

$n = 2 \: or \: n = 10$

We put n=2 into the equation to get,

$\sqrt{6(2) - 11} = 2 - 3$

$1 = - 1$

This statement is false, hence 2 is an extraneous solution

We put n=10, to get

$\sqrt{6(10) - 11} = 10 - 3$

$\sqrt{49} = 7$

$7 = 7$

This is true, hence the only solution is
$n = 10$
