Answer:
A. 2^11
Step-by-step explanation:
(They are basically asking what's 2^4 × 2^7, but with more words.)
I usually do each exponent individually:
2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)
2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128
Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.
BUT, you can also:
(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)
2^4 × 2^7
4 + 7 = 11
2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).
Hope this helps friend :)

Answer:
m∠XYW = 32°, m∠WYZ= 85°
Step-by-step explanation:
6x+44-10x+65=117
-4x+109=117
-4x=117-109
=8
x=-8÷4
=-2
Hence, ∠XYW = (6x+44)°
= [6(-2)+44]°
= (-12+44)°
= 32°
Hence, ∠WYZ = 117° - 32°
= 85°

Callie got 37 pieces of Halloween candy. Her brother got 42 pieces. She wants to estimate to find about how many pieces of candy they have together. What should her first step be?
Answers
Answer:
Callie needs to hide both her and her brother's candy from him so that none is eaten/stolen. Then count each stash separately. Put the candies in groups of 10 to quickly establish that over 70 pieces were collected. Callie should steal a stack from her brother's pile while he's not looking. Just calmly shift one stack of ten candies to her side. She should announce she got 47 pieces and her brother only 32.

Answer:
A. Only A
Step-by-step explanation:
Lets take a look at Sequence A first. By translating triangle MNO along line segment NB, MNO's top left corner is now on point B, but the shape and orientation have not changed. Then, when we reflect MNO over the vertical line that goes through B, we "flip" MNO onto ABC exactly.
So Sequence A DOES map MNO onto ABC
Now let's take a look at Sequence B to see if it works too. First, we reflect, or "flip" triangle MNO over the vertical line that passes through points M and O. Now MNO and ABC have the same orientation or shape, but aren't in the same location. Next, Sequence B tells us to translate MNO along line segment MB. This puts point M on point B, resulting in the two triangles next to each other and in the same orientation, touching at point B, but not mapped onto one another.
So the answer is choice A: Only A maps MNO onto ABC

Answers
The system of equations:
5x + 10y = 30
4x + 8y = 36
Has no solutions, the correct option is C.
How to solve the system of equations?Here we have the system of equations:
5x + 10y = 30
4x + 8y = 36
We want to use the substitution method, then we need to isolate one of the variables. Let's work with the second equation:
4x + 8y = 36
Divide by 4:
x + 2y = 9
x = 9 - 2y
Now replace that in the other equation to get:
5*(9 - 2y) + 10y = 30
45 - 10y + 10y = 30
45 = 30
This is a false equation, thus, the system has no solutions.

Can someone please help how I could find the square root for 121? Please explain step by step to get marked as brainliest!
Answers
Answer:
+ or - 11
Step-by-step explanation:
To find the square root of 121, think of a number that multiplied by itself would get to 121. This number is 11. However, do remember that the number could also be negative 11 bencause a negative times a negative becomes positive. I would advise you to try memorizing the squares of 0 to 15 to help you with this. Otherwise, you can just use a calculator.

What type of variable is N?
Binomial, geometric or neither?
Answers
Since the number of trials is not fixed, N is neither a binomial or a geometric variable, it is an inverse binomial variable.
The sample is chosen at random, hence, the trials are independent, that is, each person has the same probability of answering it, hence N is not a geometric variable.
For it to be a binomial distribution, there needs to be a fixed number of trials, which there is not, hence, N is also not a binomial variable.
The distribution that counts the number of trials until x successes in the inverse binomial distribution, which means that N is an inverse binomial variable.A similar problem is given at https://brainly.com/question/25644451

-72
12° C
Step-by-step explanation:
The magnitude of a single number is the positive version of that number.
We write it mathematically like this:
|−218|=218
|-12|=12
The magnitude of a number is also known as the absolute value, and literally means the 'size' of the number, not worrying if it is positive or negative.
For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.

Athlete J runs 2/3 of a mile in 8 minutes. Athlete H runs 2 3/4 miles in 1/2 hour.
1: If Athlete J continues at that speed, how long will it take to run one mile?
2: How long will it take Athlete J to run 5 miles at that same speed?
3: Who runs faster, J or H? Why?
Answers
The number of minutes it would take Athlete J to run one mile is 12 minutes.
The number of hours it would take Athlete h to run 5 miles is 10/11 hour.
Athlete h runs faster because his average speed is greater than that of Athlete J.
In order to determine the time it would take Athlete J to run one mile, the average speed has to be determined.
Average speed = total distance / time
2/3 ÷ 8
2/3 x 1/8 = 1/12 mile / minute
Time it would take Athlete J to run one mile = distance / speed
1 ÷ 1/12 = 12 minutes
Average speed of Athlete H = 2 3/4 ÷ 1/2
11/4 x 2 = 5 1/2 miles / hour
Time it would take Athlete H to run 5 miles = distance / speed
5 ÷ 11/2
5 x 2/11 = 10/11 hours

How many different four-digit numbers can be formed with the numbers 7; 4; 5; 1; 2; 9; and 8?
Answers
One is with the repetition of digits.
The other is without repetition of digits.
ANSWER 1: With Repetition
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360
