Hello!

The answer is (−4)(7)

To get this answer you must add -2+9 and get 7. -4 stays the same. so your answer will be (-4)(7).

Your answer will be 28.

Answer:

8:02 AM

Step-by-step explanation:

Find out how many minutes it takes to travel one mile:

60 divided by 45= 1.333334 minutes

It takes 1.333334 minutes to travel 1 mile, how long will it take to travel 100 miles:

1.333 times 100 = 133.3334

133.3334 rounds to 133 minutes

Add 15 minutes because you want to arrive early

133+15=148

Divide it by 60

148 divided by 60 = 2.466667

or do

148-120 (2 hours) = 28 minutes

It will take 2 hours and 28 minutes to get there

10:30-2:28= 8:02

If Tammy takes out a discounted loan for $850 at a simple interest rate of 12%, but only receives $800 into her bank account, wh

Vikki [24]

Answer : The duration of the loan is, 6 months

Step-by-step explanation :

First we have to determine the discounted money.

Discounted money = $850 - $800 = $50

Thus, interest = $50

Now we have to determine the time of loan.

Formula used :

$S.I=\frac{PRT}{100}$

where,

P = principle

R = interest rate

T = time

S.I = simple interest

Now put all the given values in the above formula, we get:

For 1 year : $\$50=\frac{(\$850)\times (12)\times T}{100}$

For 12 months : $\$50\times 12=\frac{(\$850)\times (12)\times T}{100}$

$T=5.88month\approx 6month$

Thus, the duration of the loan is, 6 months

A scuba diver returning to the surface swims to move up quickly, then waits a few meters below the surface to avoid pressure iss

Juliette [100K]

Given:

The function f represents the diver's distance from sea level over time, in seconds.

$f(x)=\begin{cases}3x+1 & \text{ if } -9$

To find:

The correct statement for the domain.

Solution:

Domain is the set of input values for which the function is defined.

Here, x values are the input values and they represent time intervals on which the function is defined

Here, the possible intervals for x are $-9$ .

$Domain=(-9,-2]\cup (-2,1]\cup (1,7)$

$Domain=(-9,7)$

Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.
