Answer:
90
Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted
The number of units the 10% sales decline represents is 90
what is percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Given here projected sales = 900 but the actual sales is 10% less than this amount , thus actual sales = 900 - 10% of 900
= 900 -( 10/100 )×900
= 900 - 90
= 810
Hence, the number of units the 10% sales decline represents is 900-810 =90

Are the ratios 5:3 and 6:4 equivalent?
yes
no
Answer:
nope
Step-by-step explanation:
The given ratios 5:3 and 6:4 are not equivalent.
What are Equivalent ratios?Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.
Two or more ratios can be compared with each other to check whether they are equivalent or not.
The given two ratios are 5:3 and 6:4
We can write them as 5/3 and 6/4
Let us apply subtraction, if we get 0 then these are equivalent.
6/4-5/3

How would u solve this??
Answer:
n=1, m=3, and p=-4
Step-by-step explanation:
Take the fourth root of both sides
so x^n*y^m*z^p=x*y^3*z^-4;
notice z has a negative exponent because it was in the denominator
therefore, n=1, m=3, and p=-4

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster. Which graph represents the set of heights that satisfy this requirement?
A number line going from 50 to 58. An open circle is at 53. Everything to the right of the circle is shaded.
A number line going from 50 to 58. An open circle is at 54. Everything to the right of the circle is shaded.
A number line going from 50 to 58. A closed circle is at 54. Everything to the right of the circle is shaded.
A number line going from 50 to 58. A closed circle is at 55. Everything to the right of the circle is shaded.
Given:
Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.
To find:
The graph that represents the set of heights that satisfy this requirement.
Solution:
Let x be the height required for the ride.
Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.
[tex]x\geq 54[/tex]
So, 54 and all values above 54 are in the solution set.
Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.
Therefore, the correct option is C.

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2 + 34 = 10x
Answer:
So the intermediate step in question is (x - 10)² = 66
Step-by-step explanation:
Let's find out:
x² + 34 = 10x
x² - 10x = -34
x² - 20x + 100 = 66
(x - 10)² = 66
x - 10 = ± √66
x = 10 ± √66

James is purchasing a new pair of AirPods for $199.99. If the tax rate is 9%, how much will he spend?
Given:
Price of new AirPods = $199.99
Tax rate = 9%
To find:
How much will he spend?
Solution:
We have,
Price of new AirPods = $199.99
Tax rate = 9%
Tax value = 9% of $199.99
= [tex]\dfrac{9}{100}\times 199.99[/tex]
= [tex]17.9991[/tex]
Now,
Total money spend = Price of AirPods + Tax
= [tex]199.99+17.9991[/tex]
= [tex]217.9891[/tex]
[tex]\approx 217.99[/tex]
Therefore, the total money spend by James is $217.99.

Given:
32 and 28 are the two numbers.
To find:
(a) The GCF of 32 and 28.
(b) Using the GCF, find the factor of (32-28).
Solution:
(a)
The factor forms of the given numbers are:
[tex]32=2\times 2\times 2\times 2\times 2[/tex]
[tex]28=2\times 2\times 7[/tex]
It is clear that, 2 and 2 are the common factors in both.
[tex]GCF(32,28)=2\times 2[/tex]
[tex]GCF(32,28)=4[/tex]
Hence, the GCF of 32 and 28 is 4.
(b)
Using the GCF we need to find the factor of (32-28).
[tex]32-28=4\times 8-4\times 7[/tex]
Taking out the GCF, we get
[tex]32-28=4\times (8-7)[/tex]
Hence, [tex]32-28=4\times (8-7)[/tex].

Which pair of numbers has a sum of 0?
Group of answer choices
0, 7
-7, 7
7, 14
-7, 14
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7

Answer:
(3, - 2 )
Step-by-step explanation:
Given the 2 equations
4x - 2y = 16 → (1)
y = - 5x + 13 → (2)
Substitute y = - 5x + 13 into (1)
4x - 2(- 5x + 13) = 16 ← distribute and simplify left side
4x + 10x - 26 = 16
14x - 26 = 16 ( add 26 to both sides )
14x = 42 ( divide both sides by 14 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 5(3) + 13 = - 15 + 13 = - 2
solution is (3, - 2 )

What is the answer to this problem? Abby had $6.00 to spend on a treat with his 3 friends. If he spends the same amount on his 3 friends, what is his maximum amount of money he can spend on each person?
Answer:
$2.00
Step-by-step explanation:
Abby had $6.00 to spend on a treat with his 3 friends.
We are told in the question that: If he spends the same amount on his 3 friends
Hence: the maximum amount of money he can spend on each person is calculated as:
$6.00/3 friends
= $2.00
Therefore, the maximum amount of money that he can spend on each friend is $2.00
