Eric and pam are paid $48.75 for their work. Eric worked 2.5 hours, and pam worked 4 hours. They split the money according to the amount of time each of them worked. How much is erics's share of the money? Explain.
Answer:
$18.75
Step-by-step explanation:
Determine the total hours worked by both individuals = 2.5 + 4 = 6.5 hours
Determine the fraction of hours that Eric worked = 2.5/6.5 = 0.384615
Multiply this fraction by the total amount earned = 0.384615 x $48.75 = $18.75
On a multiple-choice test, a student has four possible choices for each question. The student receives 1 point for a correct answer and loses ¼ point for an incorrect answer. If the student has no idea of the correct answer for a particular question and merely guesses, what is the student's expected gain or loss on the question? Suppose you were using an
Answer:
1 / 16
Step-by-step explanation:
Number of options = 4
Number of correct answers = 1
Number points gained for a correct answer = 1
Number of points lost for an incorrect answer = 1/4 = 0.25
Probability of choosing a correct option = 1/4
Probability of choosing an incorrect option = 3/4
x ____ 1 ______ - 1/4
P(x) __ 1/4 ______ 3/4
Expected gain or loss :
E(x) = Σx*p(x)
E(x) = (1 * 1/4) + (-1/4 * 3/4)
E(x) = 1/4 - 3/16
E(x) = (4 - 3) / 16
E(x) = 1 /16
A gain of 1/16

100 91
First:
you make them into fractions (hint: 100 is ALWAYS the denominator of your percent)
Second:
You multiply 10 and 91 which gives you 910
Third:
910

Sia sells large candles for $3 each and small candles for $2 each. She sold 17 candles for $46.00. How many of each size candle did she sell? 4 small and 13 large candles 5 small and 12 large candles 12 small and 5 large candles 13 small and 4 large candles
Answer:
The number of large size candles sells are 12 and the number of small size candles are 5 .
Step-by-step explanation:
As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y. Equation becomes
x + y = 17
3x + 2y = 46
Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .
3x - 3x + 2y - 3y = 46 - 51
-y = - 5
y = 5
Put in the equation x + y = 17 .
x + 5 = 17
x = 17 - 5
x = 12
Therefore the number of large size candles sells are 12 and the number of small size candles are 5
Each quadrilateral below is a parallelogram . find the missing measures .
Answer:
AD = 8
DC = 15
m∠A = 112°
m∠B = 68°
m∠C = °
Step-by-step explanation:
If we're working with parallelograms, we can assume that each line and it's opposite are perfectly parallel.
To find AD, all you need to do is look to the opposite line, BC. Since This is a parallelogram, AD = BC, so AD is 8.
To find DC, you do the exact same. Find the opposite line that it is parallel to, in this case that's AB, and since AB = DC, you know that DC = 15.
To find m∠A, let's look at m∠D. Since m∠D = is 68°, We can use that knowledge to find m∠A. Since the two angles are right beside each other on the same line, together they would equal 180° if you added them up. But since you don't know what m∠A is, you just have to subtract 68 from 180.
180 - 68 = 112.
To find m∠B, We simply look back to m∠D. Since m∠B is directly opposite to m∠D, That means they have the same value, 68°.
And finally, to find m∠C, we do the same thing we did to find m∠B. m∠C is directly across from m∠A - we have already found m∠A, and we know that it is 112°. Therefore, m∠C is 112° as well.

On parallelogram ABCD, if A(3,-4) B(10,-2) C(8,-9) and D(1,-11), what are the coordinates of E?
Answer:
(5.5 , - 6.5)
Step-by-step explanation:
Diagonals of a parallelogram bisect each other.
E (x , y) : midpoint of segment AC or segment BD
x = (3 + 8) / 2 = 11/2 = 5.5
y = (-4 + -9) /2 = -13/2 = - 6.5
Answer:
E(5.5,-6.5)
Step-by-step explanation:
We simply draw the parallelogram in coordinate system and read the coordinates of E.
A running track design is composed of two half circles connected by two straight-line segments. Garrett is jogging on the inner lane (with radius r) while Devin is jogging on the outer (with radius R). If r= 30 meters and R= 33 meters, how much longer does Devin have to run to complete one lap?
Answer:
18.86 m
Step-by-step explanation:
From the given question, both covers the same distance of the straight line segment.
For the inner lane,
length of arc of its semicircle = [tex]\pi[/tex]r
= 30 x [tex]\frac{22}{7}[/tex]
= 94.2857
So that,
the total length for the two halves of the inner lane = 2 x 94.2857
= 188.5714 m
For the outer lane,
length of arc of its semicircle = [tex]\pi[/tex]r
= 33 x [tex]\frac{22}{7}[/tex]
= 103.7143
The total length for the two halves of the outer lane = 2 x 103.7143
= 207.4286 m
The difference between the two = 207.4286 - 188.5714
= 18.8572 m
Therefore, Devin would run 18.86 m more to complete one lap.

the circumference of a circle is about 48.042 yards. the circle's diameter is ___ yards.
use 3.14 for pi.
Step-by-step explanation:
Given
Circumference of circle = 48.042 yards
diameter (d) = ?
we know
Circumference = πd
or, 48.042 = 3.14 * d
or, d = 48.042 / 3.14
Therefore d = 15.3 yards
The circle's diameter is 15.3 yards.

A board game uses a fair six-sided die and a spinner with five equal-sized sections colored dark blue, green, light blue, red, and yellow. Players roll the die and then spin the spinner. Match each probability statement to its correct value. the probability of getting a 6 and any color except a shade of blue the probability of getting a 5 and a shade of blue the probability of getting an even number and a shade of blue the probability of getting at least 3 and any color except a shade of blue the probability of a getting at most 4 and yellow
The probability of getting a 6 and any color except a shade of blue is 2/15.
The probability of getting a 5 and a shade of blue is 1/30.
The probability of getting an even number and a shade of blue is 1/10.
The probability of getting at least 3 and any color except a shade of blue is 4/15.
The probability of getting at most 4 and yellow is 2/15.
We have,
The probability of getting a 6 and any color except a shade of blue:
This probability involves rolling a 6 on the die and getting any color except a shade of blue on the spinner.
Since the die has six equally likely outcomes and the spinner has four colors that are not shades of blue, the probability is (1/6) x (4/5) = 2/15.
The probability of getting a 5 and a shade of blue:
This probability involves rolling a 5 on the die and getting a shade of blue on the spinner.
Since the die has six equally likely outcomes and the spinner has one shade of blue section, the probability is (1/6) x (1/5) = 1/30.
The probability of getting an even number and a shade of blue:
This probability involves rolling an even number (2, 4, or 6) on the die and getting a shade of blue on the spinner.
Since the die has three even numbers and six equally likely outcomes, and the spinner has one shade of blue section, the probability is (3/6) x (1/5) = 1/10.
The probability of getting at least 3 and any color except a shade of blue:
This probability involves rolling a number greater than or equal to 3 on the die and getting any color except a shade of blue on the spinner.
Since the die has four outcomes (3, 4, 5, or 6) that satisfy this condition, and the spinner has four colors that are not shades of blue, the probability is (4/6) x (4/5) = 4/15.
The probability of getting at most 4 and yellow:
This probability involves rolling a number less than or equal to 4 on the die and getting yellow on the spinner.
Since the die has four outcomes (1, 2, 3, or 4) that satisfy this condition, and the spinner has one yellow section, the probability is (4/6) x (1/5) = 2/15.
Thus,
The probability of getting a 6 and any color except a shade of blue is 2/15.
The probability of getting a 5 and a shade of blue is 1/30.
The probability of getting an even number and a shade of blue is 1/10.
The probability of getting at least 3 and any color except a shade of blue is 4/15.
The probability of getting at most 4 and yellow is 2/15.
