syeda has finished 20% of her math assignment. The assignment includes 50 problems how many problems has syeda completed?
Answer:
10 problems
Step-by-step explanation:
This is the answer because:
1) We have to solve for what 20% of 50 is since she finished 20% of her test:
20% of 50 = 10
[tex]\frac{2}{10}[/tex] × [tex]\frac{50}{1}[/tex] = [tex]\frac{100}{10}[/tex] = 10
Therefore, the answer is 10 problems.

ASAP!! (12y + 8) (5y + 2) 2x st (sy
Answer:
y = 10
x = 64
Step-by-step explanation:
the equations containing y are adjacent angles in a parallelogram, meaning that they are supplementary, so we can create an equation:
5y + 2 + 12y + 8 = 180
solve this to get y = 10
the equation for x would be 2x + 5y + 8 = 180 because these angles are also supplementary
solve this to get x = 64
Through : (-2,-1), slope =3

Answer:
y = 3x +5
Step-by-step explanation:
Maybe you want the equation of the line with slope 3 through point (-2, -1).
The point-slope form of the equation of a line is useful for this:
y -k = m(x -h) . . . . line with slope m through point (h, k)
y +1 = 3(x +2) . . . . the equation with your point and slope
y = 3x +5 . . . . . . . rearranged to slope-intercept form

The temperature is 2 degrees and drops to -15 degrees overnight. Write and then evaluate a subtraction expression to determine the change in temperature.
Answer:
-17 degrees
Step-by-step explanation:
Given that:
Initial temperature = 2 degrees
Final temperature = -15 degrees
To Determine:
The change in temperature.
Solution:
First of all, let us have a look at the method for calculating the change in any quantity.
Let the initial quantity = [tex]a[/tex]
Let the final quantity = [tex]b[/tex]
Change in quantity = Final quantity - Initial quantity = [tex]b - a[/tex]
Here, we are given the quantity as temperature.
where [tex]a = 2[/tex] degrees and
[tex]b = -15[/tex] degrees
Therefore, the change in temperature = -15 - 2 = [tex]\bold{-17}[/tex] degrees
which of the following depicts a graph of a polynomial with a positive leading coefficient?
Answer:
c
Step-by-step explanation:
Graph B is the graph of a polynomial with a positive leading coefficient.
What are coefficients?
A coefficient is a multiplicative factor in some term of a polynomial, a series, or an expression.
If the leading coefficient is positive, the function will extend to + ∞.
Hence, Graph B is the graph of a polynomial with a positive leading coefficient.

Answer: y=2x+4
Step-by-step explanation:
the line hits at 4 on the y axis and I did 2 rise, 1 run.
Answer: y = 2x+4
Step-by-step explanation:
The b-value (y-intercept; the value of y when x = 0) is 4.
The slope is rise over run, or the change in y over the change in x. The "rise" between two distinct points is 2 for every one change in space for the x-value. Thus, the slope (m) is 2.
Plug these values into the sample equation y = mx + b, and you should have your solution.

Which number is both a factor of 60 and a multiple of 3?
Answer:
15 because 3x5=15 and 60/4=15
The required number is a factor of 60 and a multiple of 3 are 12, 15, and 30.
Given that,
To determine the number is both a factor of 60 and a multiple of 3.
The factor is defined as the number that can divide another number and gives a perfect real number.
Here,
The factor of 60 are,
2 × 30 = 60
3 × 20 = 60
4 × 15 = 60
5 × 12 = 60
6 × 10 = 60
And also the number which is divisible by 3 are 12, 15, and 30.
Now the number which is a factor of 60 and divisible by 3 are 12, 15, and 30.
Thus, the required number is a factor of 60 and a multiple of 3 are 12, 15, and 30.

what is 25% of 30= 7.5
Answer:
you have it right..25 percent of 30 is 7.5
Question: What is 25 percent of 30?
Percentage solution with steps:
Step 1: Our output value is 30.
Step 2: We represent the unknown value with [tex]x[/tex].
Step 3: From step 1 above, [tex]30 = 100%[/tex]%.
Step 4: Similarly, [tex]x = 25[/tex]%.
Step 5: This results in a pair of simple equations:
[tex]30 = 100[/tex]% [tex](1)[/tex].
[tex]x = 25[/tex]% [tex](2)[/tex].
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
[tex]\frac{30}{x} = \frac{100percent}{25percent}[/tex]
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{30} = \frac{25}{100}[/tex]
Therefore, [tex]25[/tex]% of [tex]30[/tex] is [tex]7.5[/tex]
Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804
Complete Question:
Yanay gets a lot of spam calls. An area code is defined to be a three digit number from 200-999 inclusive. In reality, many of these area codes are not in use, but for this question we'll simplify things and assume they all are.
Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804?
Answer:
1/6400 or 0.0000015625
Step-by-step explanation:
Given
Area Codes = 200 to 999 (inclusive)
Required
Determine the probability that back to back calls have area code 804
[First, we need to calculate the totality of area codes]
Total Area Codes = 999 - 200 + 1
Total Area Codes = 800
The probability of each code is 1/800
So, the probability of having back to back code of 804 is:
Probability = 1/800 * 1/800
Probability = (1/800)²
Probability = 1/640000
Hence, the required probability is 1/640000 or 0.0000015625
