What is the length of EF?
Diano4ka-milaya [45]

The length of EF is 3.8

<h3>How to solve for EF?</h3>

To do this, we make use of the following law of sines

EF/sin(D)= DE/sin(F)

So, we have:

EF/sin(75)= 3/sin(50)

This gives

EF = sin(75) * 3/sin(50)

Evaluate the product

EF = 3.8

Hence, the length of EF is 3.8

3x=4(c-d)/d make d the subject
MissTica

Answer:

d =  \frac{4c}{3x + 4}

Step-by-step explanation:

3x =  \frac{4(c - d)}{d}

Multiply both sides by d:

3xd = 4(c  - d)

Expand:

3xd = 4c \:  - 4d

+4d on both sides:

3xd + 4d = 4c

Factorise d out of the left-hand side:

d(3x + 4) = 4c

Divide both sides by (3x +4):

d =  \frac{4c}{3x + 4}

Bonnie deposits $70.00 into a new savings account. The account earns 45 % simple interest per year , s added or removed from the
nordsb [41]

Answer:

\$164.5

Step-by-step explanation:

Bonnie deposits $70.00 into a new savings account.

The account earns 45% simple interest per year.

She neither added or removed from the savings account for 3 years.

We know that,

i=\dfrac{P\cdot r\cdot r}{100}

here,

i = interest,

P = principal = $70,

r = rate of interest = 45%,

t = time = 3 years,

Putting the values,

i=\dfrac{70\cdot 45\cdot 3}{100}=\$94.5

So the total amount will be,

=\text{Principal}+\text{Interest}

=70+94.5

=\$164.5
