t = 14.9 years

Solution:

Given data:

I = $688.38, P = $550, r = 8.4%, t = ____ years

Simple interest formula:

$I=\frac{Prt}{100}

$688.38=\frac{550 \times 8.4  \times t}{100}

Switch the sides.

$\frac{550 \times 8.4  \times t}{100}=688.38

Multiply by 100 on both sides.

$\frac{100 \times 550 \times 8.4 t}{100}=688.38  \times 100

$550 \times 8.4 t=68838

4620 t=68838

Divide by 4620 on both sides.

$\frac{4620 t}{4620}=\frac{68838}{4620}

$t=\frac{149}{10}

t = 14.9

Hence t = 14.9 years.

Plz help, I don't understand this.
Oksanka [162]

Answer:

see explanation

Step-by-step explanation:

consecutive even integers have a difference of 2 between them

for example 2, 4, 6 are 3 consecutive even integers

In general if we let the first integer be k then the next 2 integers are

k + 2 and k + 4

the sum of these equals 4 times the first integer, that is 4k, hence

k + k + 2 + k + 4 = 4k

3k + 6 = 4k ( subtract 3k from both sides )

6 = k

the 3 consecutive integers are

k = 6

k + 2 = 6 + 2 = 8

k + 4 = 6 + 4 = 10

that is 6, 8 and 10

note that sum = 6 + 8 + 10 = 24

and 4 × 6 = 24

confirming the sum of the 3 integers equals 4 times the first integer

Help!! This doesn't make any sense to me. Can anyone help me solve for the value of x?

<em>Exterior angle of the triangle is equal to the sum of the opposite angles.</em>

9x = 5x + 9 + x

<em>Combine like terms:</em>
9x = 6x + 9

<em>Take away 6x from both sides:</em>
3x = 9

<em>Divide by 3 on both sides:</em>
x = 3

Answer: x = 3

Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.
BigorU [14]

Answer:

5 5/8 miles per hour

Step-by-step explanation:

Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.

We are asked to write the unit rate , this means we are to find out how many miles he can run per hour

Hence,

2/3 hour = 3 3/4 miles

1 hour = x

Cross Multiply

2/3 hour × x = 3 3/4 miles × 1 hour

x = 3 3/4 miles × 1 hour/ 2/3 hour

x = 3 3/4 ÷ 2/3

x = 15/4 ÷ 2/3

x = 15/4 × 3/2

x = 45/8

x = 5 5/8 miles per hour
