Solve for n.
–18.4 = 3.2(n + 3) + 0.8
please help!!
Answer: n= -9
Step-by-step explanation:
-18.4 = 3.2(n + 3) + 0.8
-18.4 = 3.2n + 9.6 + 0.8
-18.4 = 3.2n + 10.4
-28.8 = 3.2n
-9 = n
Which angles are supplementary to <5?
Explain your reasoning.
Answer:
Both <6 and 7 would be supplementary to <5
Step-by-step explanation:
Supplementary means two angles that add up to 180 degrees, and 180 degrees is a straight line. Taking that into account adding <6 and 5 add up to 180 together. Same with <8 and 5.
Rita had a roll of film developed for $7.38. Her flash wasn't working so only 9 pictures turned out. How much did each picture cost her?
A.
$16.38
B.
$1.64
C.
$0.82
D.
$66.42
Answer:
D. $66.42
Step-by-step explanation:
If I'm correct (which I highly doubt...)
You multiply 7.38 and 9
That should give $66.42
Sorry if I'm wrong...
And if I'm wrong, my second option would be C. $0.82
The ages of two groups of karate students are shown in the following dot plots:
picture shown below:
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
Group A has greater variability in the data.
Group A has less variability in the data.
Group B has a lower range.
Group B has a lower mean
Answer:
Group A has less variability in the data.
Step-by-step explanation:
Since the range of group a is 10 (14 - 4), while group B has a range value of 19 (26 - 7) therefore group A has less variability in the data.
Multiply One and three-fourths × Four-fifths.
One and three-fourths written as an improper fraction is
7/4
.
The product written as an improper fraction in lowest terms is
.
The answer written as a mixed number is
.
Multiply One and three-fourths and Four-fifths...
1 3/4 x 4/5 = ?
To multiply, you have to change 1 3/4 to 7/4.
7/4 x 4/5 = ?
7 x 4 = 28
4 x 5 = 20
The product written as an improper fraction in lowest terms is...
20/28 can be lower. 20 divided by 4 = 5. 28 divided by 4 = 7.
So, the lowest term written as an improper fraction is 5/7.
The answer written as a mixed number is...

Fatimah is driving at 1.5 km in 2 min. What is distance she covered in 2 1/4 h?
Answer:
101.25 km
Step-by-step explanation:
To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.
1.5 km = 2 minutes
divide both sides by 2.
1 minute = 0.75 km
2.25 hours = 2.25 * 60 = 135 minutes
Multiply the speed by the time to find distance.
135 * 0.75 = 101.25 km
Thus, she covered 101.25 km in 2 1/4 hours.

Pls help, 20 points! A number cube is rolled d360 times, and the results are recorded as follows: 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes. What is the experimental probability of rolling a 2 or a 3?
It would help if you could put the answer in decimal form but you don't have to :D
Answer:
The experimental probability of rolling a 2 or a 3 is 2/9 or 0.222222 (go as long as you like :D)
Step-by-step explanation:
Total number of times cube roller = T = 360,
we have 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes
The probability of rolling a 2 is,
since we get 31 twos out of 360 rolls,
P(2) = 31/360
The probability of rolling a 3 is,
since we get 49 threes out of 360 rolls,
P(3) = 49/360
the experimental probability of rolling a 2 or a 3 is the sum of these two,
so,
P(2 or 3) = P(2) + P(3) = 31/360 + 49/360 = 80/360 = 2/9
P(2 or 3) = 2/9
In decimal form, P(2 or 3) = 0.2222222
The experimental probability of rolling a 2 or a 3 is 2/9 or (0.2222) .
The number of times a 2 or a 3 was rolled is the sum of the occurrences of twos and threes,
P(2) = 31
P(3) = 49
P(2) + P(3) = 31 + 49 = 80.
The total number of rolls is given as 360.
Now, calculate the experimental probability:
Experimental probability of rolling a 2 or a 3 = Number of times a 2 or a 3 was rolled / Total number of rolls
P(2 or 3) = 80 / 360
After simplifying the fraction:
Experimental probability of rolling a 2 or a 3 = 2/9
Therefore, the experimental probability of rolling a 2 or a 3 is 2/9.

Which expression has the same value as 20 − 4 ⋅ 3
a. 20 − (4 ⋅ 3)
b. (20 − 4) ⋅ 3
c. 20 + 4 − 3
d. 20 ⋅ 4 − 3
Answer:
a. 20 - (4 ⋅ 3)
Step-by-step explanation:
PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Please note that multiplication 4 ⋅ 3 will happen before the subtraction -
If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!
This means that answer a. must be correct.
We verify:
20 − 4 ⋅ 3 = 20 - 12 = 8
a. 20 − (4 ⋅ 3) = 20 - 12 = 8
b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48
c. 20 + 4 − 3 = 21
d. 20 ⋅ 4 − 3 = 80 - 3 = 77
Answer: A: 20 - (4 x 3)
Step-by-step explanation:
In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.
________________________________________________
Kenzie has $7.25. What is the maximum number of scrunchies she can buy?
______________________________
Answer:
48
Step-by-step explanation:
20 scrunchies=3 dollars
7.25 dollars = ?
1 dollar=6.66666666
0.25 dollar=1.666666666666
7*6.66666666=46.666666
:)
Answer:
Kenzie can buy 48 Scrunchies
Step-by-step explanation:
You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

What is the solution to the equation below? log 20xrise 3-2logx=4
Answer:
\(x = 500\)
Step-by-step explanation:
Given
\(log20x^3 - 2logx = 4\)
Required
Solve for x
\(log20x^3 - 2logx = 4\)
Using law of logarithm which says;
\(nlogx = logx^n\)
The expression becomes
\(log20x^3 - logx^2 = 4\)
Also, using laws of logarithm which says:
\(loga - logb = log\frac{a}{b}\)
The expression becomes
\(log(\frac{20x^3}{x^2}) = 4\)
\(log(20x) = 4\)
Also, using laws of logarithm which says
\(If\ loga = b\\then\ a = 10^b\)
The expression becomes
\(20x = 10^4\)
\(20x = 10000\)
Divide through by 20
\(\frac{20x}{20} = \frac{10000}{20}\)
\(x = \frac{10000}{20}\)
\(x = 500\)
