Answer: There are 75 Adults in the supermarket ask me why if you want a full on explanation. The full on reason of why it is 75 is because if you have a ratio of 1:5 and you now the one is for the kids and it is 15. Then you add 15 from 1 until you get to the 5th ratio. Hence, it brings you all the way to 75 adults. I hope this helped you, and anyone else

Find EF and FD on number line
D = -6.1, E = 9, F = 17.7
SHOW YOUR WORK PLEASE!
Answer:
EF: on the same side of origin 17.7 - 9 = 8.7
FD: on the opposite of 0 17.7 + 6.1 = 23.7
Step-by-step explanation:
D = -6.1, E = 9, F = 17.7
EF: on the same side of origin 17.7 - 9 = 8.7
FD: on the opposite of 0 17.7 + 6.1 = 23.7
Can someone please help me with this question.
Answer:
Since FAB and GED are congruent they also create the same angle. The angle is shown with the curved line. AE is a straight line, or 180 degree angle. This means that FAB and ABC must create a 180 degree angle... and if FAB is congruent to GED then GED and EDC are also congruent.

Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.
Answer:
Yes
Explanation: 120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.
15 ⋅ 1.2 = 18.0 = 18
15 hours ⋅ 1.2 = 18.0 hours = 18 hours
This means that Maxine is correct.

Use the figure to find the measures of the numbered angles. ∠5 = ∠6 =
Answer:
∠ 5 = 49°, ∠ 6 = 131°
Step-by-step explanation:
∠ 5 and 49° are corresponding angles and are congruent, then
∠ 5 = 49°
∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is
∠ 6 + ∠ 5 = 180°
∠ 6 + 49° = 180° ( subtract 49° from both sides )
∠ 6 = 131°
Craig measured a length as 0.034 millimeters. What is the margin of error? 0.03 mm to 0.04 mm 0.033 mm to 0.034 mm 0.0335 mm to 0.0345 mm 0.0345 mm to 0.0350 mm
C. 0.0335 mm to 0.0345 mm
Step-by-step explanation:
The least significant digit of Craig's measurement is in the 0.001 mm place. The error in the measurement is presumed to fall within half that value either side of Craig's measurement. So, the actual value is expected to be in the range ...
0.034 - 0.0005 = 0.0335
to
0.034 + 0.0005 = 0.0345
The measurement is presumed to be in the range 0.0335 mm to 0.0345 mm.

C

2 is the right answer.A book costs $ 25.00. You have a coupon for 30 % off. Calculate the final price of the book with a 5% GST. (Begin by finding the discount price and then adding the GST)
Answer:
$18.375 or rounded = $18.38 (brainliest if correct)
Step-by-step explanation:
25.00- 7.5 = $17.5
5% of 17.5 = 0.875
17.5 +0.875 = 18.375

The parabola in the figure below has an equation of the form
y = ax^2 + bx - 4.
Find the equation of the parabola
Answer:
y = - x² + 5x - 4
Step-by-step explanation:
Given that the zeros are x = 1 and x = 4 , then the corresponding factors are
(x - 1) and (x - 4) , then
y = a(x - 1)(x - 4) ← a is a multiplier
= a(x² - 5x + 4)
To find a substitute the coordinates of any other point on the parabola into the equation.
Using (2, 2), then
2 = a(4 - 10 + 4) = - 2a ( divide both sides by - 2 )
a = - 1
Thus
y = - (x² - 5x + 4) = - x² + 5x - 4 ( with a = - 1 and b = 5 )

Find the center and the radius and the center of the circle with the given equations:
Answer:
3. (-1 , 3) , 4
4. (0 , -7), 8
Step-by-step explanation:
circle: (x-h)² + (y-k)² = r²
3. x²+2x+y²-6y-6 =0
(x²+2x+1) + (y²-6y+9) -16 =0
(x+1)² + (y-3)² = 4²
center(-1 , 3) radius: 4
4. x²+y²+14y-15=0
(x+0)² + (y²+14y+7²) - 64 = 0
(x+0)² + (y+7)² = 8²
center: (0 , -7) radius: 8
Answer:
3. Center = (-1,3) Radius = 4
4. Center = (0,-7) Radius = 8
use completion of squares to find the solution, if you do not understand what this means, there is a great video on utube by the channel Prep Expert that explains finding the center of a circle based on an equation.

A salesman needed to sell a used car. He priced it at $4,500 the first day it was on the
market. The second day he reduced the price by 12%. What was the price of the used car after this reduction?
Answer:
$3960
Step-by-step explanation:
12% of $4,500 is 540.
Subtracting the 12% means taking away $540 from $4,500, which gives you $3960

PLZ I NEED HELP AND I DON"T KNOW THE ANSWER!!
Answer:
Step-by-step explanation:
$ 3750 = truck rental; $125 per ton of sugar transported
C is cost; S is number of tons transported
Equation relating C to S would be a linear equation like y = mx + b
C = 125S + $3750
This equation would be graphed in the first quadrant only
you would start with your y-intercept at (0, 3750)
As x increases by 1, your y increases by 125 yielding these points:
(1, 3875) (2, 4000) (3, 4125) etc.
This shows that for each increase by one ton of sugar, the cost goes up $125
1)Cost of 1 ton = $ 2000
Cost of 2 ton = $3500
Cost of 3 ton = $5000
$ 1500 increase for each of ton of sugar being transported.
2) (1 , 2000) ; (2 , 3500)
Slope =
= 1500
