A school assembly had 95 students in attendance, and 80% of them were first-graders. How many first-graders were at the assembly?
Answer:
76
Step-by-step explanation:
If you multiply 95 by 0.8 (the percentage as a decimal), you get 76.
Finding a Percent of a Number A 2-column table with 4 rows titled What after school activity do you participate in question mark. Column 1 has entries sport, club, extra help, none. Column 2 has entries 40 percent, 35 percent, 15 percent, 10 percent. The table shows the results of a survey about after-school activities. If 210 students participated in the survey, how many of those students do not participate in any after-school activities? students
Answer:
21 percent
Step-by-step explanation:
First, you have to divide 210 by 10 to get 21 percent. Plus I got it correct. Please mark me brainlest.
Answer: I'm Pretty Sure Its 21
Step-by-step explanation:

Kiara made the table below to show the IQ scores and grade point averages (GPAs) of students in her class. She made another table to show the standardized test scores and IQ scores.
IQ, GPA, and SAT Scores
IQ
GPA
IQ
Standardized Test Score
120
3.7

1540
85
2.3

She graphs the data in each table and writes the rounded values as shown for the regression line y = a x + b.
I Q and G P A. a = 0.04. b = negative 0.9. I Q and Standardized Scores. A = 20. b = negative 924.
Next, Kiara uses the steps below to predict a student’s standardized test score based on the student’s GPA of 4.0.
Step 1 Write the equation of the trend line for IQ and GPA.
y = 0.04 x minus 0.9
Step 2 Write the equation of the trend line for IQ and standardized test score.
y = 20 x minus 924
Step 3 Find the IQ that is expected from a GPA of 4.0.
y = 0.04 x minus 0.9. 4 = 0.04 x minus 0.9. 4.9 = 0.04 x. 122.5 = x.
The IQ is about 122.5.
Step 4 Find the corresponding standardized test score for an IQ of 122.5.
122.5 = 20 x minus 924. 122.5 = 20 x minus 924. y = 523.
The standardized test score is 523.

An Airplane covers 1020km in an hour. How much
distance will it cover in 25/6 hours?
Answer:
4250 km
Step-by-step explanation:
Henry runs up 10 flights of stairs.
Then, he runs down 10 flights of stairs.
Does this situation represent additive
Inverses? Explain.
Answer:
Yes, it does
Step-by-step explanation:
When we add a number to its additive inverse, the resulting value is zero
The first case is running up 10 flights which we consider positive
then he runs down 10 flights of stairs; this we can consider as - 10
So adding this together, we have -10 + 10 to give zero
What this mean is that we have added a number to its additive inverse

Answer:
The value of x will be:
[tex]x=-5[/tex]Step-by-step explanation:
Given the equation
[tex]4-2(x+7)=3(x+5)[/tex]
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
[tex]4-2x-14=3x+15[/tex]
simplifying the equation by subtracting 14 from the L.H.S
[tex]-10-2x=3x+15[/tex]
Subtracting 15 from both sides
[tex]-10-2x-15=3x+15-15[/tex]
[tex]-25-2x=3x[/tex]
combining the like terms
[tex]-25=3x+2x[/tex]
[tex]-25=5x[/tex]
dividing both sides of the equation by 5
[tex]\frac{-25}{5}\:=\:\frac{5x}{5}[/tex]
[tex]-5=x[/tex]
Therefore, the value of x will be:
[tex]x=-5[/tex]Consider the sequence.

Write the equation of a line through (2,4) and (-6, 8) in any form.
Answer:
Step-by-step explanation:
y=mx+c.... first find m(gradient/slope)
m=Y2-Y1/X2-X1
m=8-4/-6-2
m=4/-8
m=-1/2
Then find c
Take any point and fix in x and y
4=-1/2(2) +c
4=-1 +c
c=4+1=5
Therefore y=-1/2x+5
y+1/2x-5=0

what is the parallel slope intercept form pls help?
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.
[tex]-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b[/tex]
Now that we have the y-intercept, we can create the equation.
[tex]y = 4x - 17[/tex]
We can prove this by graphing both lines, like so.
Determine the slope of the line that passes through these points (3,9) and (-7,11)
Answer:
-5
Step-by-step explanation:
To calculate the gradient of the slope, we have to calculate the [tex]\frac{rise}{run}[/tex].
[tex]\frac{3-(-7)}{9-11}[/tex] = [tex]\frac{3+7}{-2}[/tex]
[tex]\frac{3+7}{-2}[/tex] = [tex]\frac{10}{-2}[/tex]
[tex]\frac{10}{-2}[/tex] = -5
