Answer: Hello!
-2-(-5) can also be written as -2 + 5.
When subtracting a negative, you're essentially adding, because you are subtracting a negative value. So we would add 5 to -2.

Alan buys 5.3 ounces of sour patch kids candy. After sharing with his friends he returns to buy an additional 6.75 ounces. How many ounces did he buy in all?
Answer:
Alan buys 12.05 ounces of sour patch kids candy in all.
Step-by-step explanation:
We are given that Alan buys 5.3 ounces of sour patch kids candy. After sharing with his friends he returns to buy an additional 6.75 ounces.
And we have to find the total ounces he buys in all.
As we know that for finding the total quantity or amount, we will use addition for calculating it.
Firstly, Alan buys = 5.3 ounces of sour patch kids candy
Additional ounces of sour patch kids candy Alan buys = 6.75
So, the total ounces of sour patch kids candy he buys in all = 5.3 + 6.75
= 12.05 ounces
Hence, he buys 12.05 ounces in all.
Which are the coordinates of the x-intercept in the equation −4x+5y=20 ?
Answer: (-5,0)
Step-by-step explanation:
-4x + 5y = 20 the x intercept is when y is zero so input zero into the equation and solve for x.
-4x + 5(0) = 20
-4x = 20
x = -5

Answer:
To convert binary into decimal, multiply each binary digit with a power of 2 corresponding to its position.
So for example 1010 would be 1·2³ + 0·2² + 1·2¹ + 0·2⁰ = 8+2 = 10 in decimal.
now you can calculate the answers yourself!
To convert decimal into binary, you can use the following approach:
Write down the answer from right to left
A. if your number is odd, write down a 1, if it is even, write a 0
B. divide the number by 2 and round down, ie. discard any decimals (e.g., 7 / 2 = 3)
C. repeat step A until your number is 0.
example:
18 -> write down 0
18/2 = 9 -> write down 1
9/2 = 4 -> write down 0
4/2 = 2 -> write down 0
2/2 = 1 -> write down 1
1/2 = 0 finished
The result is 10010.

If two parallel lines are cut by a transversal,
then alternate interior angles are congruent.
Since one alternate interior angle measures 60 degrees,
the other alternate interior angle must also measure 60 degrees.

A cubic polynomial can have atmost
---zeros
Answer:
3Step-by-step explanation:
Any polynomial can only have as many zeros as is the highest exponent at x.
A cubic polynomial it's: ax³+bx²+cx+d. The highest exponent at x is 3 so it is the largest number of its zeros.
Kyle lives in a state that has 6% sales tax. If c represents the cost of an item and t represents the sales tax on the item, which equation expresses the relationship between these two variables
Answer:
t = 0.06c
Step-by-step explanation:
Given the following :
Percentage sales tax on items = 6%
Cost of item = c
Amount of sales tax on item = t
Amount of sales tax is the product of the sales tax percentage and the cost of item purchased
Hence, Amount of sales tax;
t = 6% × cost of item (c)
t = 0.06 × c
t = 0.06c

Step-by-step explanation:
Factor:
2x^2+9x+9
=(2x+3)(x+3)
Answer:
(x + 3)(2x + 3)
Step-by-step explanation:
Sum = 9
Product = 2*9 = 18
Factors = 6 ,3
2x² + 9x + 9 = 2x² + 6x + 3x + 3 * 3
= 2x ( x + 3) + 3( x + 3)
= (x +3)(2x + 3)

Kristen has an area of 70 square feel for a flower garden she plants 5 varieties of flowers equally in her garden which ratio shows the square feel per flower type
Answer:
Each flower type area ratio = 14 ft²
Step-by-step explanation:
Given:
Total area = 70 ft²
Total equal varieties = 5
Find:
Each flower type area ratio
Computation:
There is 5 equal part of land
So,
Ratio = 1:1:1:1:1
Assume each part cover = x
So
Total area = 5x
5x = 70 ft²
x = 14 ft²
Each flower type area ratio = 14 ft²

Domain is [tex]0 \le x \le 12[/tex]
Range is [tex]0 \le y \le 900[/tex]
============================
Explanation:
The smallest x can be is x = 0. The largest x can be is x = 12. This is shown as the left-most and right-most values of the graph. We could have x be anything between 0 and 12, including both endpoints, so we say the domain is [tex]0 \le x \le 12[/tex]. Recall the domain is the set of all allowed x inputs of a function.
---------------------
The range is the set of all possible y outputs. The smallest y output possible is y = 0, and the largest is y = 900. The range is therefore [tex]0 \le y \le 900[/tex] meaning y is between 0 and 900, including both endpoints.
Both domain and range endpoints happen to be at the x and y intercepts. This won't always be the case.
A sample of 100 consumers shows that the average amount spent annually on a debit card is $8000. And assume that the population standard deviation of debit card expenditure is $500. Construct a 95% confidence interval of the population mean amount spent annually on a debit card.
Answer:
The confidence interval is ($7902, $8098)
Step-by-step explanation:
The formula for confidence interval of a normal distribution is given as:
Confidence Interval = μ ± z × σ/√n
Where:
μ is the mean amount spent annually = $8,000
σ is the standard deviation = 500
n is the number of samples = 100 customers
z = 95% confidence interval = 1.96
Confidence Interval = $8000 ± 1.96 ×500√100
= $8000 ± 1.96 × 500/10
Confidence Interval = $8000 ± 1.96 × 50
= $8000 ± 98
= $8000 - 98 = $7902
= $8,000 + 98 = $8098
Therefore, the 95% confidence interval of the population mean amount spent annually on a debit card = ($7902, $8098)
Given that point A is the midpoint of line segment ED, where E( -1,9) and A(4,5), what is the location of point D?
Answer:
D(9, 1)
Step-by-step explanation:
A being the midpoint means its coordinates satisfy ...
A = (E + D)/2
Solving for D, we find ...
D = 2A -E
= 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)
D = (9, 1)
Estimate the median number of texts sent per day by this group of middle school students.
Answer:
33 i think
Step-by-step explanation:
Answer:
49.5 texts
Step-by-step explanation:
The total number of students is
11+21+33+23+12 = 100
The middle is 50
150 is in the middle group
The median will be between 40 -59
The best estimate for the median is to add the 40+59 and divide by 2
(40+59)/2 = 99/2 = 49.5 texts

convert 2.16161616 to a rational number in the form of a/b
Answer:
[tex]\frac{214}{99}[/tex]
Step-by-step explanation:
We require to create 2 equations with the repeating digits after the decimal point. Then by subtracting them we eliminate the repeating part.
let x = 2.1616.... → (1)) ← multiply both sides by 100
100x = 216.1616..... → (2)
Subtract (1) from (2)
99x = 214 ( divide both sides by 99 )
x = [tex]\frac{214}{99}[/tex]
Hi pls help if you’re good at trigonometrytysm
Answer:
a = 80
b = 310
c = 96
Step-by-step explanation:
1)
20 + a + a = 180
2a + 20 = 180
2a = 160
a = 80
2)
180 - 65 - 65 + b = 360
b + 50 = 360
b = 310
3)
52 + c + 32 = 180
c + 84 = 180
c = 96
