Answer:
Members that voted yes = 15 Members
Step-by-step explanation:
Members that voted yes : members that voted no = 5 : 1
Total ratio = 5 + 1 = 6
total school board members that voted = 18
how many voted yes for new math books?
Members that voted yes = 5/6 × 18
= 0.8333333333333 × 18
= 15 members
Members that voted yes = 15 Members
members that voted no = 1/6 × 18
= 0.1666666666666 × 18
= 3
members that voted no = 3 members
Ellen has a bag with 3 red marbles and 2 blue marbles in it. She is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. 3 red marbles and 2 blue marbles What is the best prediction for the number of times that Ellen will draw a blue marble?
Answer:
120
Step-by-step explanation:
Blue marbles = 2
Red marbles = 3
Total marbles = 2 + 3 = 5
If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :
P(drawing a blue marble) = number of blue marbles / total number of marbles
= 2 /5 = 0.4
Predicted number of times blue is drawn in 300 selections :
300 * 0.4 = 120
Approximately 120 times
write an equation in slope-intercept for the line that has a slope of 1/2 and goes through the point (4, 7)
Answer:
y = 1/2x + 5
Step-by-step explanation:
The formula for an equation is y = mx + b
m is the slope. It is given
y = 1/2x + b
b is the y-intercept
In this case, we must substitute to find the y-intercept
We are given coordinate pair (4,7)
Plug our pair in and we get => 7 = 1/2(4) + b
=> 7 = 2 + b
easily, we find b = 5
We get our equation: y = 1/2x + 5

The circumference of a circle is approximately 131.88 centimeters What is the area of the shaded region (6/10 of a circle)
Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2
can someone pls help i’ll mark you brainliest pls pls pls it’s due in 10 min
Answer:
Step-by-step explanation:
1) r = 5mm; d = 10 mm
2) r = 6 cm; d = 12 cm
3) r = 9 m; d = 18 m
4) r = 8 km; d = 16 km
5) r = 11 m; d = 22 m
6) r = 15 mm; d = 30 mm
7) r = 13 km; d = 26 km
8) r = 7 cm; 14 cm

Each car on a computer train holds 20 people. On a particular morning, 5 cars were 90% full and 3 cars were 65% full. If the people were rearranged to fill as many cars as possible, how many cars would be filled?
Answer:
7 cars
Step-by-step explanation:
The computation of the number of cars to be filled is shown below:
A car that is 90% full and the total people is 20 so 90% would be
= (.90)(20)
= 18
A car that is 65% full and the total people is 20 so 65% would be
= (.65)(20)
= 13
Now
Total number of people = (5)(18) + (3)(13).
= 129
Now the number of cars to be filled is
= 129 ÷ 20
= 6.45
= 7 cars
b. If C(a) is the cost in dollars to plant a acres of soybeans, what does C-1(35,000) represent?
9514 1404 393
Answer:
the number of acres planted for a cost of $35,000
Step-by-step explanation:
If the function C gives the dollar cost of planting a certain acreage, then the inverse function C^-1 gives the acreage planted for a given dollar cost.
C^-1(35000) gives the acreage planted for a cost of $35,000
find the distance between the points (-4,-2) and (3,3)
Answer:
8.6
Step-by-step explanation:
Use the distance formula to find the distance between the two points.
√[(x₂ - x₁)² + (y₂ - y₁)²]
√[(3 - -4)² + (3 - -2)²]
√[(7)² + (5)²]
√[(49) + (25)]
√74

Answer:
[tex]x=\sqrt{41}[/tex]
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2}+ b^{2}=c^{2}[/tex]
Answer:
Option B
Step-by-step explanation:
Pythagorean Theron is:
[tex]a^2+b^2=c^2\\\\\text{a and b - legs}\\\text{c - hypotenuse}[/tex]
We would be solving for 'c', or the hypotenuse.
[tex]4^2+5^2=c^2\\\\16+25=c^2\\\\41=c^2\\\\\boxed{\sqrt{41}, -\sqrt{41} =c}[/tex]
The correct answer should be option B.

Answer:
-1 and 4/3
Step-by-step explanation:
Given the quadratic equation;
f(x) = 3x^2-x-4
To get all potential roots, we will equate f(x) = 0
3x^2-x-4 = 0
3x^2-4x+3x-4 = 0
x(3x-4)+1(3x-4) = 0
(x+1)(3x-4) = 0
x+1= 0 and 3x-4 = 0
x = -1 and 3x = 4
x = -1 and x= 4/3
Hence the potential roots are -1 and 4/3

In a class, there are twice more boys than girls. Six boys leave the class and six girls arrive ;
therefore, there are twice more girls than boys .
How many boys and girls were there at first ?
please show calculations steps plus this should be solved as a system
Answer:
Boys= 12
Girls= 6
Step-by-step explanation:
Let no: of girls be 'x'
No: of boys= 2x
boys after= 2x-6
girls after = x+6
according to the question,
2(2x-6)=x+6
4x-12=x+6
3x=18
x=6
No: of girls at first= 6
No: of boys at first=2*6=12
