Answer:

The temperature range is $95^o$ , going from $-45^0$ to $40^o$

Step-by-step explanation:

The temperature range is the difference between the maximum and the minimum temperature:

$40^o-(-45^o)=40^o+45^o=95^o$

The temperature range is $95^o$ , going from $-45^0$ to $40^o$

Answer:

1) b and m

2) m∠8=m∠6

3) 160°

4)x=60°

Step-by-step explanation:

1) all straight lines sum to 180°

subtract the angles given from 180°

the other angle for b is 25°, while the other angle for m is 155°

so we can see that the angles for both lines are the same, hence they are parallel.

2) ∠8 should be the same as ∠6, ∠10 should be the same as ∠3, ∠7 same as ∠5 and ∠9 same as ∠4

in the options we are only given '∠8 should be the same as ∠6' as the correct answer, so we take that.

3) from the image we can see that both horizontal lines are parallel to each other, so both angles on the lines should be same, so ∠CET would be (2x-16)°

(2x-16)°+(7x+20)°=180°

we get x=20(nearest whole number)

∠CED=7x+20=7(20)+20=160°

4) since we need to show that they are parallel,

(2x+30)°=(4x-90)°

2x-4x=-90-30

-2x=-120

x=60

we then plug the x value into the two equations, in which we get 150° for both the angles [2(60)+30=4(60)-90] ⇒ (150=150)

I hope u understand it the way I put it.

Which is equal to log base 2n=4

o-na [289]

To solve this problem you must apply the proccedure shown below:

1. You have the following logarithm:

<span>log(2)n=4

2. Therefore, you con rewrite it as below:

loga(b)=logb/loa
</span>
3. Therefore, you have:

log(2)n=4⇒log(n)/log(2)=4

4. Then, you obtain:

log(n)=4log(2)

5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:

log(n)=4log(2)

Help me please explain do not need work just explain THANK YOU I NEED HELP

Mnenie [13.5K]

Alright,

you will need to solve for each variable to find if they got the equation correctly or not..

Let's start with h
isolate h
(1/2)h = A/(b1+b2)
Now we need to get rid of 1/2 we may do so by multiplying both sides by 2

h = 2(A/(b1+b2))

And that's not how they did it for h so Option D doesn't apply

Let's see C
Also doesn't apply since they multiplied 2 only by A rather than A/h

Let's see B
Also not correct they made the same mistake as with option C

Let's see A
again same mistake
when multiplying both sides by 2
the 2 should be as following
$2\frac{A}{h}$

I believe you should contact your instructor and explain that non of the options is right.
