Abba grew 1 foot over the past year. He is now 5 feet tall. What was Abba's percent increase in height?
Step one:
given data
We are told that Abba grew 1 foot in the past year, and now he is 5 feet tall, this means that his previous height is 4 feet.
Step two:
We want to find the percent increase
%increase = change in height/ previous height *100
%increase =5-4/4*100
%increase = 1/41*100
%increase =0.25*100
%increase = 25%
Answer:
He grew 1/5 = 20%
he was 4/5 = 80%
now he is 5/5 = 100%
Step-by-step explanation:
a college says it admits only people with sat scores among the top 10%. how high an sat score does it take to be g
Full question:
Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.
If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?
Answer and explanation:
To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students
A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28
We use algebra to find the score to be eligible thus:
1.28=x-500/100
x-500=128
x=128+500
x=628
Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores
Grace plans to visit her friend in another state. The distance to her friend is 1797 miles. If she leaves on Friday and drives 5 hours at a time at 70 mph, when will she get there?

Answer:
Step-by-step explanation:
10+60t≤280
60t≤280-10
60t≤270
6t≤27
2t≤9
t≤9/2
t≤4.5
t=4 hours
first subtract $10 from$280 and you get $270
270 divided by 60 = 4.5
so the answer is four and a half hours

A bag has 5 balls: 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange
(0)
You randomly choose a ball. What is the sample space?
OA. (RG, Y, B, O)
OB. (R,G, Y, B, P)
Oc. (G, )
OD. (R, G, Y, B)
Answer: R,G,Y,B,O
Step-by-step explanation: Sample space is just any and all possible outcomes
The sample space of the given experiment is (R,G, Y, B, O). So option A is the correct one.
What is a Sample Space?A sample space is a set of all the possible outcomes in a random experiment. It is usually denoted by the letter, S.
The subset of the sample space are events.
Given experiment is that you randomly choose a ball from a bag which consists of 5 balls.
Balls are 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange (O).
Each ball is of different color.
When you randomly choose a ball, the chosen ball can be any of the colors given.
So sample space = (R,G, Y, B, O)
Hence the required sample space is (R,G, Y, B, O).

Which ordered pair is a solution of the equation?
y = -2x+ 5
Choose 1 answer:
a.Only (2, -9)
b.Only (-2,9)
c.both (2, -9) and (-2,9)
d.neither
Answer:
Only (-2, 9) is the solution of the equation.
Hence, option 'b' is correct.
Step-by-step explanation:
Given the equation
y = -2x+ 5
Checking the ordered pair (2, -9)
substituting x = 2 and y = -9 in the equation
y = -2x + 5
-9 = -2(2) + 5
-9 = -4 + 5
-9 = 1
FALSE!
L.H.S ≠ R.H.S
Thus, the ordered pair (2, -9) is NOT a solution of the equation.
Checking the ordered pair (-2, 9)
substituting x = -2 and y = 9 in the equation
y = -2x + 5
9 = -2(-2) + 5
9 = 4 + 5
9 = 9
TRUE!
L.H.S = R.H.S
Thus, the ordered pair (-2, 9) is a solution of the equation.
Conclusion:
Only (-2, 9) is the solution of the equation.
Hence, option 'b' is correct.

Answer:
The Area of the sector is: A = 95.4 cm²
Step-by-step explanation:
Given
Central angle Ф = 135°
radius r = 9 cm
To determine
Area of the sector = ?
The Area of the sector can be calculated using the formula
A = Ф/360 × πr²
substitute Ф = 135°, r = 9 and π = 3.14
A = 135/360 × (3.14) (9)²
A = 95.4 cm²
Therefore, the Area of the sector is: A = 95.4 cm²

Answer:
r = -11
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1) = slope
(5-r)/(4-8) = -4
(5-r)/ -4 = -4
5-r = 16
-r = 11
r = -11
im not sure but i beleive this is how you do it.
you find the agreegable slope, and then multiply it by the y value.
