68 is 17% of what number?
Enter
Answer:
400
Step-by-step explanation:
Is means equals and of means multiply
68 = 17% * what number
Change to decimal form
68 = .17 * what number
Divide each side by .17
68/.17 = .17/.17 what number
400 = what number
The number is 400
68 is approximately 17 percent of 400.
To find out what number 68 is 17% of, we can use the following formula:
(17 / 100) x = 68
Let's solve for x:
(17 / 100) x = 68
To isolate x, we can multiply both sides of the equation by (100 / 17):
x = (68 × 100) / 17
x ≈ 400
Therefore, 68 is approximately 17% of 400.
To understand this calculation, think of the percentage as a proportion or ratio. In this case, we are trying to find the ratio of 68 to the unknown number. The result, 0.17, represents how much of the unknown number 68 comprises. By multiplying this ratio by the unknown number, we obtain the value of x, which is approximately 400. Thus, 68 is roughly 17% of 400, indicating that 68 represents 17% of the value 400.

Question 2 - Brianna spends 7 3/5 hours in school each day. Her lunch period is 30
minutes long, and she spends a total of 42 minutes switching rooms between classes.
The rest of her day is spent in 6 classes that are all the same length. How long is each
class?
Answer:
64 minutes
Step-by-step explanation:
7⅗ hours = 7⅗ × 60 min
= 38/5 × 60
= 456 minutes
456 - 30 - 42 = 384 minutes for 6 classes
384/6 = 64 minutes per class
what is -5x+-33x x= what
Answer: -38x
Step-by-step explanation: We will be solving for x.
Since both values in the equation have a variable of x, simply add -5x to -33x.
x is already simplified so we can not technically solve for it.
-5x + (-33x) = -38x (We could add the two values since they are equivalent, but we can not solve for x.)

Point R was rotated about the origin (0,0) by 90° clockwise.
Which figure is the image of R?
The mapping rule for a 90° clockwise rotation is (x, y) → (–y, –x), so R ( 2, -5) becomes (-5, -2).
Answer:Point C is the image of R.
The point C is the image of R.
Here,
Point R was rotated about the origin (0,0) by 90° clockwise.
We have to find the image of R.
What is 90 degree Clockwise rotation?
To rotate the figure 90 degrees clockwise about a point, every point (x,y) will rotate to (y, -x).
Now,
By figure;
Point R is ( 2, -5 )
Now, Point R was rotated about the origin (0,0) by 90° clockwise.
The image of point (x, y) = (y, -x)
Hence, the image of R = (-5, -2 ) = Point C
So, by graph;
Point C is image of Point R.

Answer:
52 m
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 39^2 = 65^2
a^2 + 1521 = 4225
4225 - 1521 = 2704
Square root of 2704 = 52
Answer:
52m
Step-by-step explanation:
as this is a right angled triangle (has a 90° angle), you can use the Pythagoras theorem to work out the missing side.
Pythagoras theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
side A squared (labeled on diagram below)
+ side B squared
= side C squared
for this example though, we don't know the length of side B so we need to swap around the formula.
[tex]c^{2} - a^{2} = b^{2}[/tex]
replace the letters for their numbers,
[tex]65^{2} - 39^{2} = b^{2}[/tex] (calculate)
[tex]65^{2} - 39^{2} = 2704[/tex]
2704 = b² but we want b by itself so we will square root b² (2704)
[tex]\sqrt{2704} = 52[/tex]
∴ side B = 52m (remember we were calculating in meters)

2. How many congruent angles does an isosceles right triangle have?
What are the measures of the three angles?
Final answer:
An isosceles right triangle has two congruent angles, which are both 45 degrees. The right angle measures 90 degrees.
Explanation:
An isosceles right triangle has two congruent angles. In this type of triangle, the two legs that form the right angle are of equal length. Let's call that length 'x'. The hypotenuse, which is the side opposite the right angle, is equal to 'x' times the square root of 2. The congruent angles in an isosceles right triangle are both 45 degrees, and the right angle measures 90 degrees.

A water bottle rocket is shot upward with an initial velocity of vi = 40 ft/s from the roof of a school, which is at hi = 70 ft above the ground. The equation h = −
1
2
at2 + vit + hi models the rocket's height as a function of time. The acceleration due to gravity a is 32 ft/s2.
We are to find how long will it take to return to the ground?
Answer:
t = 0.48 sec
Step-by-step explanation:
We are given;
initial velocity; vi = 40 ft/s
hi = 70 ft
acceleration due to gravity; a = 32 ft/s²
Now, we are given that the rocket's height as a function of time is;
h = -12at² + vit + hi
At ground, h = 0
Plugging in the relevant values to obtain ;
0 = -12(32)t² + 40t + 70
-384t² + 40t + 70 = 0
The roots of the equation gives; t = 0.48 sec
The scores of a dart game are 46, 25, 33, 56, 31, 46, 49, 55, a, b, and c. If 33 is the only mode, 46 is the median, and a>c, what is the possible range of values for a?
The possible range of values for 'a' in the dart game score sequence, considering 46 as the median and 33 as the mode, is from 47 to 55.
Explanation:In the list of dart game scores 46, 25, 33, 56, 31, 46, 49, 55, a, b, and c, with the information that 33 is the mode, 46 is the median, and a > c, we can deduce the following:
As 46 is the median in a list of 11 scores, it is the 6th score when the list is ordered. Thus, there must be four scores greater than 46 which are 49, 55, a, and b assuming that b also must be greater than or equal to 46 as a > c and a and b are both greater than c.
Since 46 is not a mode, there cannot be a third instance of it among the scores a, b, or c. This implies a and b cannot be 46. Therefore, a has to be at least 47.
Now, we also know that a is greater than c, but we do not have any other scores to compare c with. Given that we don't know if c is greater than 46, 46 could potentially be c that would make a at least 47, thus the range of possible values for a starts from 47 to any number greater than that but not 56 as the next score after 55 is 56 which is not a as a > c. Therefore, a could technically be any score above 47 that is less than 56, so the range for a is 47 to 55.
What is the volume of this container
Answer:
1,875 cm^3
Step-by-step explanation:
To find the volume of the big square you would multiply 20x5x20= 2,000
to find the volume of the little square you would multiply 5x5x5= 125
Then to find the Volume of the square with the hole in it you would subtract 2,000 and 125 which = 1,875 cm^3

The histogram displays the tree growth in one year for a sample of trees measured at Shady Farms.
How many trees measured grew 10 or more inches over the year?
How many trees are represented in the histogram?
Answer:
1.48 2.100
Step-by-step explanation:
To find out how many trees grew 10 or more inches, you should look at the '10 or more inches' section of the histogram and check the frequency, which represents the tree count. To find the total number of trees represented, you should add up the frequencies of all growth rate sections.
Explanation:To determine how many trees measured grew 10 or more inches over the year, you need to look at the histogram for the section that represents 10 or more inches. The y-axis of a histogram indicates frequency, which in this case, means the number of trees. Count the number of instances within the section for 10 or more inches. The total number of trees represented in the histogram can be found by adding the frequency (tree counts) for each section which corresponds to tree growth rates.
For example, if the '10 or more inches' section shows a frequency of 20, it means 20 trees grew 10 or more inches over the year. If the frequencies corresponding to all growth rates total up to 50, it means the histogram represents 50 trees.
