Paula sets off from home at 13:20 and drives to Taunton for km at a speed of km/h. After 40 minutes, she drives back home on the
Veronika [31]

Answer:

Paula will arrive at her house at 15:20.

Step-by-step explanation:

Since Paula sets off from home at 13:20 and drives to Taunton for km at a speed of km / h, and after 40 minutes, she drives back home on the same route, but drives twice as slowly, to determine at what time Paula will arrive back home, the following calculation must be performed:

13:20 + 00:40 + (00:40 x 2) = X

14:00 + 1:20 = X

15:20 = X

So, Paula will arrive at her house at 15:20.

For what value of x does mz1 = 90° ?<br> 100°<br> x + 10)
sp2606 [1]

Answer:

You can solve this with common sense, but I'll do it for you and read my explanation before you demand an answer.

Step-by-step explanation:

When you look at a right angle, one forms 90°

A square has 4 sides, each should measure 90°.

That is how we know that point C measures 90°.

Now let's solve for x.

100+(x+10)+90°=90°

Solve the equation:

100+x+10+90=90

Step 1 : Solve for both sides.

100+x+10+90=90

(x)+(100+10+90)=90 ADD LIKE TERMS!

x+200=90

Step 2: Subtract 200 from both sides so you can make them equal.

x+200−200=90−200

x=−110

So, we get that <em>x=-110</em>. So <em>the blank side</em> should measure <em>90 degrees</em>.

Please help me ???? i don't remember if i should round up or down
Tpy6a [65]

Here is a saying 5 and above give it a shove (round up) 4 and below go down low (round down). In your case you would leave it the same, because when rounding you would round to the nearest 10th.

Example:

54 would round down to 50 and 55 would be rounded up to 60.

14&gt;-2(2z+3)<br>please help me!!
Veseljchak [2.6K]

Answer:

14 > -2 (2z + 3)

First you need to distribute the -2 inside the parentheses.

14 > -2(2z) + -2(3)

14 > -4z - 6              -Add 6 to both sides of the equation

14 + 6 > -4z - 6 + 6

20 > -4z              -Now divide by -4 on both sides

20 / -4 > -4z / -4

-5 > z

However, when you divide by a negative number, you MUST flip the sign.

So, the answer is:

-5 < z

Hope this helps!
