Answer:
The percentage of school time missed by the average student during 2009/2010 school year in Detroit is 23.08%.
Step-by-step explanation:
The percentage of school time missed by the average student during 2009/2010 school year in Detroit can be calculated as follows:
Percentage of school time missed = (Average number weeks of school missed / Total number of weeks in a school year) * 100 ................... (1)
Where;
Average number weeks of school missed = 9
Total number of weeks in a school year = 39
Substituting the values into equation (1), we have:
Percentage of school time missed = (9 / 39) * 100
Percentage of school time missed = 0.230769230769231 * 100
Percentage of school time missed = 23.0769230769231%
Rounding to 2 decimal places, we have:
Percentage of school time missed = 23.08%
Therefore, the percentage of school time missed by the average student during 2009/2010 school year in Detroit is 23.08%.
If a circle has a radius of 8 cm, what is its diameter?
a.
8 cm
c.
4 cm
b.
16 cm
d.
½ cm
Answer:
A = 16cm
B = 32cm
C = 8cm
D = Sorry the time I learned this I didn't learn it for fractions.
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pie you can calculate the circumference.
The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance.
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd.

m_1 =
m22

m3 =
m24 =
52
m25 =
Answer/Step-by-step explanation:
✔️m<1 + 52° = 180° (consecutive angles angle)
m<1 = 180 - 52
m<1 = 128°
✔️m<2 = 52° (alternate interior angles are congruent)
✔️m<3 = 47° (alternate interior angles are always equal)
✔️m<4 + 47° = 180° (consecutive angles)
m<7 = 180 - 47
m<7 = 133°
✔️m<5 = 180 - (52 + 47)
m<5 = 180 - 99
m<5 = 81°
pls can any one solve this
All the angles make a full circle which needs to equal 360 degrees.
Add all the angles together to equal 360:
X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360
Combine like terms:
9x -30 = 360
Add 30 to both sides:
9x = 390
Divide both sides by 9:
X = 390/9
X = 43.3333. ( 43 and 1/3)
Answer:
x = 43 1/3 degrees.
Step-by-step explanation:
All these angles add up to 360 degrees , so we have:
x - 10 + 4x - 20 + 2x - 10 + x + 10 + x = 360
9x - 30 = 360
9x = 390
x = 390/9
= 43 1/3 degrees

What is a quadratic equation? And how do you solve them?
Answer:
A quadratic equation is some thing like
(x+2)^2
or
(x+2)(x+5)
In order to solve them, the most basic method is the FOIL method
F-First
O-Outside
I-Inner
L-Last
So for example
(x+2)^2
Which is basically
(x+2)(x+2)
So the first is the 2 Xs
(x+2)(x+2)
x*x=x^2
The outer is the x and the 2,
(x+2)(x+2)
2*x=2x
Now the Inner which is the 2 and the x
(x+2)(x+2)
2*x=2x
And finally the last which is the 2 and the second 2
(x+2)(x+2)
2*2=4
Now add them all up
X^2+2x+2x+4
Combine like terms
x^2+4x+4
There you have it
Do the same with every other quadratic equation
an electronics warehouse ships televisions and DVD players in certain combinations to retailers throughout the country. The weight of 4 Televisions and 6 DVD players is 70 pounds, and the weight of 2 televisions and 5 DVD players is 37 pounds. Let represent the amount of pounds per TV and represent the amount of pounds per DVD. How much did each television and DVD player weigh?
Answer:
d = 1
t = 16
Step-by-step explanation:
Television = t
DVD = d
4t + 6d = 70
2t + 5d = 37
2t + 5d = 37
2t = 37 - 5d
2t/2 = 37/2 - 5d/2
t = 18.5 - 5/2d
4t + 6d = 70
4(18.5 - 5/2d) + 6d = 70
74 - 10d + 6d = 70
-4d = -74 + 70
-4d = -4
-4d/-4 = -4/-4
d = 1
2t + 5d = 37
2t + 5(1) = 37
2t + 5 = 37
2t = 37 - 5
2t = 32
2t/2 = 32/2
t = 16
Check: d = 1; t = 16
4t + 6d = 70
4(16) + 6(1) = 70
64 + 6 = 70
70 = 70
2t + 5d = 37
2(16) + 5(1) = 37
32 + 5 = 37
37 = 37

A right triangle has vertices at (0,9), (4,9) and (4, 4). What is the equation of the line that includes the hypotenuse? y =
Answer:
y = - 1.25x + 9
Step-by-step explanation:
A(0,9) B(4,9) C(4,4)
AB² = (4-0)² + (9-9)² = 16
AC² = (4-0)² + (4-9)² = 41
BC² = (4-4)² + (4-9)² = 25
AC is hypotenuse with y interception of 9
slope = 5/4 = -1.25
equation: y = - 1.25x + 9

Teal Street is the line 2x - 3y = 9 Write out this equation as y = mx + b
Answer:
[tex]y = \frac{2}{3} x - 3[/tex]
Step-by-step explanation:
For the equation to be written in the form of y=mx+b, ensure that the y term is on one side of the equation and bring the rest to the other side. Then divide the whole equation by the coefficient of y, so that the resulting coefficient of y is 1.
2x -3y= 9
-3y= -2x +9 (-2x on both sides)
Dividing both sides by -3:
[tex]y = \frac{2}{3} x - 3[/tex]
☆ coefficient is the number that comes before a term
In a standard deck of cards, what is the probability of drawing a face card?
Answer (round) to the hundredth place value.
Reasoning:
There are 12 face cards since there are 3 face cards in any suit, and 4 suits. So 3*4 = 12.
There are 52 cards total.
Dividing the values leads to 12/52 = 0.230769 which rounds to 0.23

The factory produced 6,260 gallons of orange juice during the rest of the week. How many gallons of apple juice did they produce during the rest of the week? blank
gallon(s)

the ratio is 1:8
blank gallons of orange juice per 1 gallon of app
le juice is 1/8
8 gallon of apple juice = 1 gallon of orange juice
1 gallon of apple juice = 1/8 gallon of orange juice
1920 gallon of apple juice = 1/8 * 1920 gallon of orange juice
= 1/8 * 1920 = 240 gallon of orange juice
1 gallon of orange = 8 gallon of apple
6260 gallon of orange = 8 * 6260 gallon of apple
= 50080 gallon of apple juice

DE is a Mid-segment of triangle ABC. How long is DE?
Answer:
DE = 14
Step-by-step explanation:
Since, DE is a Mid-segment of triangle ABC.
Therefore,
DE = 1/2 * AC
2 DE = AC
2(5x - 1) = 3x + 19
10x - 2 = 3x + 19
10x - 3x = 19 +2
7x = 21
x = 21/7
x = 3
DE = 5x - 1
DE = 5*3 - 1
DE = 15 - 1
DE = 14
