Hii! I need help with this question! The question is "You have 8 hours to get ready and 5 1/2 of those hours have already passed. How much time do you have left?" Someone help ASAP!
Answer:
2 1/2 hours
Step-by-step explanation:
Answer:
3 1/2 hours left
Step-by-step explanation:
Write an equation for this:
8 - 5 1/2 = how much time you have left
(8 is the total hours, you subtract since the hours passed, and 5 1/2 is the amount of hours passed)
Solve equation:
8 - 5 = 3, add the 1/2
So, 8 - 5 1/2 = 3 1/2 or 3.5
match the value with the appropriate ratio

Josie wants to build a slide that is 15 feet long. If the angle of elevation for the side will be 30 degree, how high in feet will the top of the slide be ?
Answer: 7.5
Step-by-step explanation: draw a right triangle to represent the slide. the slide is 15 feet long, so the hypotenuse of the right triangle would be 15 feet. The angle from the bottom is 30 degrees according to the question. You want to find the angle opposite from the 30 degree angle so use sin(30). Sin=opposite/hypotenuse so sin(30)=x/15 sin(30) is 1/2 so 1/2=x/15. You multiply by 15 on both sides to get x by itself. 1/2*15=7.5

Answer:
72 meters
Step-by-step explanation:
12 times 9 is 72
Answer:
243 m²
Step-by-step explanation:
Given the scale is 4 : 6 = 2 : 3 , then
scale of areas = 2² : 3² = 4 : 9
area of scale drawing = 12 × 9 = 108 cm²
let x be the actual area then using proportion
[tex]\frac{4}{108}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )
4x = 972 ( divide both sides by 4 )
x = 243
Actual area = 243 m²

Solve the equation. x6−9=7 x = ___ (type only an integer - no words, variables, or equal signs)
Answer:
We want to solve the equation:
x*6 - 9 = 7
To solve this we need to isolate x in one side of the equation.
First, we need to add 9 in both sides of the equation to get:
(x*6 - 9) + 9 = 7 + 9
x*6 - 9 + 9 = 16
x*6 = 16
Now we can divide both sides by 6, to get:
x*6/6 = 16/6
x = 16/6 = 2.66
This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.
If the equation was something like:
x/6 - 9 = 7
Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:
x/6 = 7 + 9 = 16
x/6 = 16
x = 16*6 = 96
x = 96
Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"

Step-by-step explanation:
Jana, a high school principal, hosted a movie event at her school. Jana's assistant kept track of the number of students in each grade who attended the event. The distribution shown in the table
represents the number of students in each grade that were present.
Grade Level
Sophomore-56
Senior-70
Freshman-52
Junior-60
Jana knows that the grade levels are equally distributed across the school of 1,200 students. She would like to use a chi-square test to see if the proportion of individuals in each class at the
movie are also equally distributed. How many seniors would be expected at the event?
Answer:
59.5 Seniors expected
Step-by-step explanation:
"Equally distributed" means that it is expected that each grade has equal number of students for 1200 schools. This means 1200/4 = 300 students expected in each grade for 1200 students. The proportion would be 300/1200 = .25
The actual total of the school shown is (56+70+52+60) = 238
Therefore 238 * .25 = 59.5 expected students in each grade for this school
The proportion for each grade can also be found by just knowing that each grade has the same proportion.There are 4 grades so 1/4 = .25

The box and whisker plots represent the number of minutes spent by users on two different social media groups. Which THREE statements are correct when comparing the plots?
A) The median time for users of Group B is 40 minutes.
B) Group B has greater median value than Group A.
C) The data for Group B varies slightly more than Group A.
D) The spread of the data for Group A is 25 minutes.
E) The spread of the data for Group A is 40 minutes.
Answer: I feel the answer is C
Step-by-step explanation:
The three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.
What is a box and Whisker plot?A box and whisker plot displays the minimum value, lower quartile (Q1), median, upper quartile (Q3), and maximum values of a data set.
Let's analyze each of the given statements given the box and whisker plots for both groups:
Statement A is TRUE:
Median time for Group B = 40.
Statement B is FALSE:
Median value for Group A is between 45 and 50
Median value for Group A is 40.
Therefore, Group B does NOT have median value greater than Group A.
Statement C is TRUE:
The interquartile range (IQR) for Group A and Group are similar, therefore, data for Group B varies slightly more than Group A.
Statement D is TRUE while E is FALSE:
Spread for Group A (IQR) = 55 - 30 = 25 minutes
Therefore, the three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

A cylinder has height of 7 inches and a base with a diameter of 9 inches.
whats the volume ? Round to the nearest tenths if needed.
Will mark b if correct!!:)
Answer:
527.6 cubic inches
Step-by-step explanation:
The volume of a cylinder is represented by the formula [tex]V = \pi r^{2} h[/tex], where r represents the radius of the base and h represents the height.
In this question, the diameter is given as 9 inches. Since the radius is half the diameter, the radius will be 4.5 inches.
Substituting in the values and solving, we get:
[tex]V =9 \pi (4.5)^{2}\\V = 9\pi(20.25)\\V = 182.25\pi\\V = 572.6[/tex]
The Volume will be 527.6 cubic inches
