If y varies directly with x and y=95 when x=5, find x when y=38.
Answer:
X is 2
Step-by-step explanation:
the equation is Y = 19X
when X=5, Y=95
when Y=38, X = 38/19 = 2
Callie surveyed 40 students at her school to see how many have dogs and/or cats. She found that 40% of students who have dogs, don't have cats.
Complete the table below.
Answer:
60 students don't have dogs
Step-by-step explanation:
Given data
number of students survayed= 40 students
40% of students have dogs
We can further find the number of students who have and don't have dogs
40/100*x= 40
0.4*x=40
x=40/0.4
x= 100 students
This means 60 students dont's have dogs
Craig washed 4/5 of the windows on a building, and
Martha washed 1/5 of them. How much greater was
Craig's fraction of the windows than Martha's?
Answer:
B
Step-by-step explanation:
Since the denominator is the same for both fractions you can just subtract 1/5 from 4/5.
(4/5) - (1/5) = (3/5)
Which of the following is impossible to draw?
-A triangle with with three 120° exterior angles
-A triangle with three acute interior angles
-None of the answers listed here are correct
-A quadrilateral with four interior acute angles
Answer: A quadrilateral with four interior acute angles
Step-by-step explanation:
If you add four angles for quadrilateral = 360 & acute angle is less than 90 degrees so it isn't possible.
the mid point of the sides of a triangle are (1,5,-1),(0,4,-2),(2,3,4) find the vertices

Find the length of AB.
6 in
130°
AB = [ 2 ]in
Answer:
Length arc AB = 3.14 in
Step-by-step explanation:
Length of arc AB = central angle/360 * 2πr
Central angle = 30°
Radius (r) = 6 in.
Substitute
Length of arc AB = 30/360 * 2*π*6
Length arc AB = 3.14 in. (Nearest tenth)

All three functions have the same minimum
Answer:
g(x)
Step-by-step explanation:
I compared the value
The function that has the smallest minimum is g(x)
Calculations and Parameters:Comparing each function individually:
The function f(x) has a minimum value of
2 * (-1)+2 = 0
The function g(x) has a minimum value of g(3) = -2
The function h(x) has a minimum value of h(1) = 3

Jenna is a 6th grader at CMS. Jenna was told her mean score on social studies quizzes was 94. She remembered getting scores of 97, 88, 90, and 95, but she knew she had taken 5 quizzes. What was her fifth quiz score?
Answer: 100
Step-by-step explanation:
Since she had a mean score of 94 in her 5 tests, then the total score will be:
= 94 × 5
= 470
Since she She remembered getting scores of 97, 88, 90, and 95, for 4 quizzes out of 5 quizzes, the total of the four quizzes will be:
= 97 + 88 + 90 + 95
= 370
Then, her 5th quiz will be:
= 470 - 370
= 100

A six sided die has the colors: red, green, green, blue, pink and yellow. The die is rolled twice. What is the probability of two rolls with at least one red outcome?
Answer:
1/6
Step-by-step explanation:
The six sided die has a total of 6 possible outcomes with red being only one of them. Therefore, this means that in a single dice roll the probability of it being red would be 1/6. Since, the question asks the probability of at least one red outcome, the second roll can be anything. Therefore, the probability of the second roll would be 6/6 or 1 and if we multiply this by the probability of the first roll it would stay the same. Meaning that the probability of getting atleast one red outcome in two rolls would be 1/6
the diameter of a circle is 20 meters . What is the area ?
Answer:
40m
Step-by-step explanation:
if 20 it the diameter then the daius is 10 which is multiplied by 4
Answer:
100pi m or approximately 314 m^2
Step-by-step explanation:
We need to find the radius to find the area
r = d/2 = 20/2 = 10
The area of a circle is
A = pi r^2
A = pi (10)^2
A = 100 pi m^2
If we approximate pi by 3.14
A = 100*3.14
A = 314 m^2

What is the solution of -17 = -2y + 13 – 8y?
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
y = 3
Alan has 3 quarters and 7 dimes in his pocket. If he takes out a coin, puts it back in his pocket, and then takes out a coin again, what is the probability that both coins are dimes?
Answer:
Probability of picking a dime both times = (7/10)^2 = 49/100, or 0.49
Step-by-step explanation:
Picking with replacement, twice from 3 quarters and 7 dimes.
Probability of picking a dime each time = 7/10.
Probability of picking a dime both times = (7/10)^2 = 49/100, or 0.49
