All angles are 90 degrees, which cancels out a kite and a rhombus, leaving you with two options (rectangle or square). Using Pythagoras' theorem, you can work out that all sides are also of equal length, which means this shape is a square :)

A large rectangular room needs to be carpeted and has dimensions 18.75 ft by 28 ft.
vichka [17]

Answer:

$13912.50

Step-by-step explanation:

First you find how much carpet you need by finding the area of the room.

18.75*28= 525ft^2

Then multiply the amount of carpet needed by 26.50 to find the total cost.

525*26.50= 13912.50

Hope this helps!

Write the phrase as an expression. Then evaluate when x=5. The sum of a number x and 4, all divided by 3
frozen [14]
Sum of a number, x and 4 all divided by 3

sum of x and 4 means x+4
all divided by 3
\frac{x+4}{3}
evaluate for x=5

\frac{5+4}{3}=
\frac{9}{3}=
3

Gina invests $1,677 in an account paying 8.61% simple interest annually. How much interest has Gina gained after six years? a. $
enot [183]

Answer:

Option (c) is correct.

The interest gained by Gini in 6 years is $ 866.34

Step-by-step explanation:

Given: Gina invests $1,677 in an account paying 8.61% simple interest annually for 6 years.

We have to calculate the interest gained by Gina in 6 years.

Using formula for simple interest

S.I.=\frac{P\times I\times T}{100}

Where,

S.I = simple interest

P is principal

R is interest rate

T is time  

Given : P = $ 1677

R = 8.61%

T = 6 years

Substitute, we get,

S.I.=\frac{1677\times 8.61\times 6}{100}

Simplify, we get,

S.I. = $ 866.3382

Rounding off to nearest hundred  we get, Interest is $866.34

Thus, the interest gained by Gini in 6 years is $ 866.34

Prove that if the set of vectors {u1, u2, u3} is linearly dependent and u4 is any vector, then the set {u1, u2, u3, u4} is linea
Lesechka [4]

Answer with Step-by-step explanation:

We are given that the set of vectors{u_1,u_2,u_3} is lineraly dependent set .

We have to prove that the set {u_1,u_2,u_3,u_4} is linearly dependent .

Linearly dependent vectors : If the vectors u_1,u_2.u_3,u_4

are linearly  dependent therefore the linear combination

a_1u_1+a_2u_2+a_3u_3+a_4u_4=0

Then ,there exit a scalar which is not equal to zero .

Let a_1\neq0 then the vector u_1 will be zero and remaining  other vectors are not zero.

Proof:

When u_1,u_2,u_3 are linearly dependent vectors therefore, linear combination of vectors of given set

a_1u_1+a_2u_2+a_3u_3=0

By definition of linearly dependent vector

There exist a scalar which is not equal to zero.

Suppose a_1\neq 0 then  u_1=0

The linear combination of the set {u_1,u_2,u_3,u_4}

a_1u_1+a_2u_2+a_3u_3+a_4u_4=0

When a_1\neq0\; and\; u_1=0

Therefore,the set {u_1,u_2,u_3,u_4} is linearly dependent because it contain a vector which is zero.

Hence, proved .
