Answer:

1. 52

2. 75

Step-by-step explanation:

PEMDAS! I love PEMDAS problems!

1. (63 - 3) / 6 + 42

(P means parenthesis first - after you do this step the parenthesis goes away)

60 / 6 + 42

(We have no exponets so we move on to doing division and multiplication from left to right)

10 + 42

(Now we add!)

2. (8*4+5^2) + 8

(Now we have to do PEMDAS inside the parenthesis - So we have to do exponents first)

(8*4 + 25) + 8

(Now you do multiplication from left to right)

(32 + 25) +8

(Now that we only have one sign in our parenthesis we can solve it to get rid of it.)

67 + 8

(now add!)

3. (13 + 5)^2 + 8 / 2

(We have to do parenthesis first because of the P)

18^2 + 8/2

(now we do exponents)

324 + 8 / 2

(Now we divide and multiply from left to right)

324 + 4

(now add!)

328

Please help me plsssssss! asappp. I'll mark brainlest and give points

Nookie1986 [14]

Answer:

Step-by-step explanation:

1)a) Abscissa of O 0

Abscissa of A 4

Abscissa of B -3 {opposite of 3}

Abscissa of C 3 {3 is the only positive integer like A}

Abscissa of D -4.5

Abscissa of E -6

Abscissa of F -1 {Midpoint of AE = (6+4)/2 = 10/2 = 5th number from -6 or 4}

b) OB = 3 units

DA = 8.5 {4.5 +4 = 8.5}

Find two positive numbers satisfying the given requirements.

Umnica [9.8K]

Answer:

8 and 19

Step-by-step explanation:

To some this, let's first list all the factors of 152. They are;

1, 2, 4, 8, 19, 38, 76, 152.

Now, let's arrange them to reflect being multiplied to get 152.

Thus;

1 × 152 = 152

2 × 76 = 152

4 × 38 = 152

8 × 19 = 152

Also, let's do the same for their sum;

1 + 152 = 153

2 + 76 = 78

4 + 38 = 42

8 + 19 = 27

Looking at the figures above, the ones that their product is 152 but have the least sum are 8 and 19

Consider rolling two fair dice and observing the number of spots on the resulting upward face of each one. Letting A be the even

Allushta [10]

Answer:

$P(E|A)= \frac{10}{11}$

Step-by-step explanation:

Given

Two rolls of die

$E \to$ one of the outcomes is 6

$A \to$ atleast one is 6

Required

P(E|A)

First, list out the outcome of each

$E = \{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)\}$

$A = \{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)\}$

So:

$P(E|A)= \frac{n(E\ n\ A)}{n(A)}$

Where:

$E\ n\ A = \{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)\}$

$n(E\ n\ A) = 10$

$n(A) = 11$

So:

$P(E|A)= \frac{10}{11}$

Two digit-

igor_vitrenko [27]

Let the number = 10x+y

x+y = 9

y-x = 1

(x+y)+(y-x) = 9+1

2y = 10

y = 10/2

x+y = 9

9-y = x

x = 9 - 5

<h2>So, your number is <u>45</u></h2>

... Hope this will help...
