Answer:

  (a) 25

  (b) (5+4)*2 +6 -2*2 -1

  (c) see below

Step-by-step explanation:

(a) evaluating exponents:

  6*7 -9*9 +64

Evaluating products:

  42 -81 +64

Evaluating sums:

  -39 +64

  25

__

(b) The last three terms of the expression sum to +1, and it is fairly easy to modify the first two terms to make one term that has a value of 18. Then the expression evaluates as 18+1 = 19.

  (5+4)*2 +6 -2*2 -1

__

(c) Evaluating parentheses:

  = 9*2 +6 -2*2 -1

Evaluating products:

  = 18 +6 -4 -1

Evaluating sums (left to right):

  = 24 -4 -1

  = 20 -1

  = 19

Pls help i always was the worst at this
Maurinko [17]

Answer:

11cm

Step-by-step explanation:

Hi, I can help.

Now to find this it is just simple subtraction but you need to know what to look for.

Let us first imagine that the top rectangle sticking out doesn't exist. Lets focus on the bottom rectangle who has the dimensions of 6 and 18cm. We need to find the ? on the top of the rectangle.

Now lets add the top rectangle. Something important to remember is that the 5cm top lines up with the ? even though it is above it.

Also, the top and bottom of a rectangle is always to going to match up / be equal.

So the 5cm + ? is going to be equal to 16cm.

So how can we use this info to find the answer? We can actually look at the 16cm and 5cm. Since the 16cm and the 5 + ? are equal we can take the 16cm at the bottom and actually take away 5cm away from it to find the ?.

So :

16cm - 5cm = 11cm

So literally that is it.

11cm is your ?

I feel like I didn't do a great job explaining this so if you have any questions AT ALL please comment or message me and I will help you anywhere its needed. :)

Pamela ran 7/10 mile on Tuesday and 3/8 mile on Thursday. How much fatter did she run on Tuesday ?
Len [333]

Answer:

Difference = \frac{13}{40}

Step-by-step explanation:

Given

Thursday = \frac{3}{8}\ mile

Tuesday = \frac{7}{10}\ mile

Required

How much farther is she on Tuesday

To do this, we simply calculate the difference between distance covered on both days.

Difference = Tuesday-Thursday

Difference = \frac{7}{10} -  \frac{3}{8}

Take LCM

Difference = \frac{28- 15}{40}

Difference = \frac{13}{40}

<em>Hence, she ran 13/40 mile farther on Tuesday</em>

Meant to be viewed in the round, the production switches form when seen from various corners. Therefore, it is clear that Pablo Picasso’s "Head of a Women" was a sculpture in the round.
