Arianna has $0.90 worth of nickels and dimes. She has 4 times as many nickels as
dimes. By following the steps below, determine the number of nickels, x, and the
number of dimes, y, that Arianna has.
Answer:
X=3
Step-by-step explanation:
0.05(4x) + 0.1x = 0.90
0.2x + 0.1x = 0.90
0.3x = 0.90
x = 3
Use the greatest common factor and the distributive property to write equivalent expressions in factored form.
13ab + 15ab =
Given:
The expression is
[tex]13ab+15ab[/tex]
To find:
The equivalent expressions in factored form.
Solution:
We have,
[tex]13ab+15ab[/tex]
In the given terms 13ab and 15ab, then common factors are only a and b because 13 is a prime number. So, the greatest common factor is ab.
Distributive property of multiplication over addition:
[tex]a(b+c)=ab+ac[/tex]
By using greatest common factor and the distributive property, we get
[tex]13ab+15ab=ab(13+15)[/tex]
[tex]13ab+15ab=ab(28)[/tex]
[tex]13ab+15ab=28ab[/tex]
Therefore, the required equivalent expression is [tex]28ab[/tex].

Scenario:
Charlie the Chocolatier mixed chocolate chips and pretzels to create 36 pounds of his holiday blend that sells for $6.00 per pound. The chocolate chips cost $7.00 per pound and the pretzels cost $4.00 per pound. How many pounds of each did he use?
Answer:
x + y = 36 (1)
7x + 4y = 216 (2)
Step-by-step explanation:
Quanrity of Holiday blend = 36 pounds
Cost per pound of the blend = $6.00
Cost of chocolate chips = $7.00 per pound
Cost of pretzels = $4.00 per pound
Let
Pounds of chocolate chips = x
Pounds of pretzels = y
x + y = 36 (1)
7x + 4y = 36 × $6.00
7x + 4y = 216 (2)
The system of equation is
x + y = 36 (1)
7x + 4y = 216 (2)

2/x= 10/15 BRAINLY it says find the unknown number in the proportion. Round the answer to the nearest hundredth when necessary
Answer:
x=3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
For this, we cross multiply and divide
so it becomes:
2 x 15 = 10x
30 = 10x
Then divide both sides by 10 to isolate x
x = 3

Cynthia invests some money in a bank which pays
5% compound interest per year.
She wants it to be worth over £8000 at the end of 3
years.
What is the smallest amount, to the nearest pound, she can invest?
Answer:
£6911 is the smallest amount Cynthia should invest to get £8000 after three years
Step-by-step explanation:
lets Assume that amount needs to invested for three years = £ x Rate of Interest = R = 5% per year Duration in years = n = 3 year
Amount expected after three years when compounded annually = A = £8000 Formula for Amount of compound interest annually is a follows A = P( 1 + R/100)^n In our case Principal P = x , Amount A = 8000 , R = 5% and n = 3( since compounded annually). On substituting these values in above formula we get 8000 = x ( 1 + 5/100)^3 ⇒8000 = x ( 105/100)^3 ⇒8000 = x ( 21/20 )^3 ⇒(8000 × 20 × 20 × 20)/(21×21×21) = x ⇒x = 6910.70≈6911
Hence £6911 is the smallest amount Cynthia should invest to get £8000 after three years

Answer:
10.68 miles
Step-by-step explanation:
17 mile radius = 34 mile diameter
34 mile diameter x 3.14 = circumference = 106.82 miles
Pi/5 radians = 36 degrees
36(106.82)/360 = 10.68 miles
Basil has five numbered cards.
Two of the numbers are hidden. 4 9 9 ? ? 8
The mode of the five numbers is 8.
The mean of the five numbers is 6
c) Work out the two hidden numbers.
Answer:
The two hidden numbers are 8 and 1.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is given by the sum of all its values divided by the number of values.
Mode of a data-set:
The mode of a data-set is the value that appears the most.
In this question:
4, 9, x, y, 8
Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:
4, 9, 8, y, 8
The mean of the five numbers is 6
This means that:
[tex]\frac{4+9+8+y+8}{5} = 6[/tex]
[tex]29+y = 30[/tex]
[tex]y = 30 - 29[/tex]
[tex]y = 1[/tex]
The two hidden numbers are 8 and 1.

Answer:
1. 25
Step-by-step explanation:
First, you need to place the numbers in ascending order, meaning from smallest to largest.
You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25
Mean (average), just add the numbers up and divide by how many numbers you have
III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer
Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem
Mode, which number appears the most times repeated
Answer:
i. 25 (range = the difference between the highest and lowest number)
ii. 30.41 (mean = sum of all numbers divided by the how many numbers there are)
iii. 6
iv. 35
v. 35

Terra wants wall-to-wall carpeting in her bedroom, which measures 10’ x 12’6”. Carpeting is on sale for $24.99 per sq. yd. What is the cost? (Remember to round your dimensions before calculating the area)
Answer:
$347.08
Step-by-step explanation:
10' x 12'6" = 125 ft^2
one yd^2 = 9 ft^2
125/9 = 13.89 yd^2
13.89 x $24.99 = $347.08
Which represents the series in sigma notation?
-5+(-1)+3+7+11
Answer:
The third answer is correct
when you plug 1 into the equation
4(1)-9= -5
4(2)-9 = -1
4(3)-9= 3
Step-by-step explanation:
The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The given series is -5+(-1)+3+7+11
The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex]
Now let us check by plugging j values from 1 to 5
When j =1,
4(1)-9= -5
When j =2
4(2)-9 = -1
when j=3
4(3)-9= 3
Hence, the sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.
