The Johnson family is going on a family trip to New York,270 miles away.They drive for 3 hours, then stop for lunch, then drive

Dmitrij [34]

Answer:

60 mph

Step-by-step explanation:

Their average speed while driving is ...

speed = distance / time

= (270 mi)/((3 + 1.5) h) = 60 mi/h

The Johnson family averaged 60 mph while driving.

Their average speed for the trip is unknown, because we don't know how long the lunch stop was.

Pls help with trig i would rlly appreciate !

Answer:

6root 85 /85 is ans..

Step-by-step explanation:

given,

a=7 and b=6

as it is a Right angled triangle

h^2=p^2+b^2

$h = \sqrt{p {}^{2} + b {}^{2} }$

so,

$\sqrt{6 {}^{2} + 7 {}^{2} }$

$\sqrt{85}$

now, sin thita=p/h

so sin thita=

$6 \div \sqrt{85}$

$=6 \sqrt{85} \div 85$

ans...

hope its helpful....

I need help with this if you get it right I will mark you brainlest

laiz [17]

The correct answer is A!

A. 1/2 is equal to .5 so multiply 2,000 by .5 and you’ll get $1000. She spends $900 on rent. Since $900 is less than $1000 she is not spending more than half of her income on rent. There for this statement is False

B. If you do 2,000 multipled by .15 (which equals 15%) then you’ll get $300 and that’s how much she spends on savings. So this statement is true.

C. 1/4 = .25 so if you do 2,000 multiplied by .25 you’ll end up with $500. The total cost of utilities, cable and groceries ( 120 + 80 + 320 ) = $520 and since $500 is less than $520 then she is spending more than 1/4 of her income on those expenses. Which makes this statement true.

D. 14% is = .14 so if you do 2,000 multiplied by .14 you’ll get $280. The total of cell phone and other expenses ( 100 + 180 ) = $280 so that is true.

Let's analyze Hannah's work, step-by-step, to see if she made any mistakes.

In Step 1, Hannah wrote $\dfrac{d}{dx} (-3+8x)$ as the sum of two separate derivatives $\dfrac{d}{dx}(-3)+ \dfrac{d}{dx} (8x)$ using the sum rule.

This step is perfectly fine.

In Step 2, $\dfrac{d}{dx}(8x)$ was kept as it is, and $\dfrac{d}{dx}(-3)$ was rewritten as $0$ using the constant rule.Indeed, according to the constant rule, the derivative of a constant number is equal to zero.

This step is perfectly fine.

In Step 3, $\dfrac{d}{dx} (8x)$ was rewritten as $\dfrac{d}{dx}(8) \dfrac{d}{dx}(x)$ supposedly using the constant multiple rule.

The problem is that according to the constant multiple rule, $\dfrac{d}{dx}(8x)
$ should be rewritten as $8 \dfrac{d}{dx}(x)$ and not as $\dfrac{d}{dx}(8)\dfrac{d}{dx}(x)$ .

Therefore, Hannah made a mistake in this step.

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if

swat32

The break even point is when C and R are equal....so set them equal

36x + 200 = 76x
200 = 76x - 36x
200 = 40x
200/40 = x
5 = x

C = 36(5) + 200 R = 76(5)
C = 180 + 200 R = 380
C = 380

so the break even point is 380
