Answer:
9/10.
Step-by-step explanation:
To determine what expression means the same as 9 divided by 10, the following logical reasoning must be carried out:
Since 9 integers are distributed among 10 dividends, this implies that these 10 will obtain a portion of those 9 integers, that is: 9/10, which gives a total of 0.90.

May 18, 11:05:10 PM When Jace runs the 400 meter dash, his finishing times are normally distributed with a mean of 81 seconds and a standard deviation of 1.5 seconds. Using the empirical rule, what percentage of races will his finishing time be between 79.5 and 82.5 seconds?
Answer:
68% of races will his finishing time be between 79.5 and 82.5 seconds
Step-by-step explanation:
Mean time = 81 seconds
Standard deviation = 1.5 seconds
According to the empirical rule : 68%, 95%, 99% lies within 1, 2, and 3 standard deviations of the mean respectively.
Hence, for a finishing time between : 79.5 and 82.5
79.5 = 81 - 1.5 (1 standard deviation to the left of the mean)
82.5 = 81 + 1.5 (1 standard deviation to the right of the mean)
Hence,
79.5 and 82.5 lies within 1 standard deviation from the mean and it is Hence has a percentage of 68%
Find the value of x.
Assuming the dark gray area is a straight line, the whole thing should add up to 180*. If we have our 180*, minus 79*, you'll have 101*. BUT, we also have to divide that by two to get our x answer, so the value of x would be 50.5*.

=-2.843028803ₓ₁₀¹⁹
9514 1404 393
Answer:
2
Step-by-step explanation:
i^4 = 1, so powers of i^4 are 1
2i^28 = 2
-3i^25 = -3(i^24)(i) = -3i
The number simplifies to 2 -3i. The real part is 2.

im lost again is getting harder for me ahhh im only in 7th grade
Answer: 72
Step-by-step explanation:
The formula for the area of a triangle is l * w / 2. In this case, the area of one triangle is 12, because 3*8=24/2=12. There are two triangles, so the combined area = 24. The area of the square is 48 because 6 * 8 = 48. Add it up, it makes 72.

20 points ! what is the area of the surface of the desk in square feet?
9514 1404 393
Answer:
B. 8.625 ft²
Step-by-step explanation:
The total area is the sum of the areas of the two rectangular sections and the area of the triangular section. The area formulas are ...
A = LW . . . rectangle
A = 1/2bh . . . triangle
Here, the dimensions are such that we can simplify the problem a bit
total area = (1.5)(2.5) +1/2(1.5)(1.5) + (1.5)(2.5)
= (1.5)(2.5 + 1.5/2 + 2.5)
= (1.5)(5.75) = 8.625 . . . . . ft²
The total surface area of the desk is 8.625 square feet.

Determine whether each pair of triangles is similar. Justify your answer.
Answer:
Your answer is C
Step-by-step explanation:
The definition of similarity is when one shape can become another after a resize, flip, slide or turn.
If you multiply AD, which is 6, by 1.5 you get 9. Which is the length AC.
If you multiply AE, which is 10, by 1.5 you get 15. Which is the length of AB.
Both triangles share angle A, so that leaves you with SAS Similarity.
Solve y=f(x) for x. Then find the input when the output is – 3.
f(x) = 1/2x-3
x=
The input is
when the output is -3.
Given:
[tex]y=f(x)[/tex]
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
To find:
The input when the output is – 3.
Solution:
We have,
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
Substituting [tex]f(x)=y[/tex], we get
[tex]y=\dfrac{1}{2}x-3[/tex] ...(i)
We need to find the input when the output is – 3. It means, we have to find the value of x when [tex]y=-3[/tex].
Putting [tex]y=-3[/tex] in (i), we get
[tex]-3=\dfrac{1}{2}x-3[/tex]
[tex]-3+3=\dfrac{1}{2}x[/tex]
[tex]0=\dfrac{1}{2}x[/tex]
Multiply both sides by 2.
[tex]0=x[/tex]
Therefore, the input is 0 when the output is -3.
What is the area of the figure?
Answer:
b. 366 square inches
Step-by-step explanation:
The area of a triangle is 1/2×Base×Height. There are 2 pairs of identical triangles so you multiply each equation by 2.
2×(1/2×10×12) = 120 in²
2×(1/2×18×12) = 216 in²
120 in² + 216 in² = 336 in²
Answer:
336 square units
Step-by-step explanation:
Generally, to find the area of the given quadrilateral (which is presumably a kite), one uses the following formula,
[tex]\frac{(base)*(hieght)}{2}[/tex]
In this picture, one can see that the diagonals (dotted lines that connect opposite corners) are given, but their measurements are split up as per the segments they are divided into. In order to find the lengths of each diagonal, add up the two parts. To find the area of the figure, substitute the results into the given formula to find the area,
[tex]12+12=24\\\\10 + 18 = 28[/tex]
Substitute,
[tex]\frac{24*28}{2}\\\\=\frac{672}{2}\\\\=336[/tex]
The shoes you want are $95. They are on sale for 40% off . What is the sale price for the shoe ?
Answer:
57
Step-by-step explanation:
90 - 40% = 57
Answer:
The shoes would be $57
Step-by-step explanation:
To calculate percentage you use the equation:
P% x N = A
Before we use it we convert the number 40 into the tenths place of a decimal, 0.40.
Now we use it!
.40 x 95 = 38
38 would be 40%, so we remove it from the last total aka 95
95 - 38 = 57
Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80. What is the new mode
Answer:
83 is still the mode
Step-by-step explanation:
The maximum possible value for the new mode is 83.
What is mode?The data value that is repeated the most in the data set is called the mode of the given data set.
Given is that Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80.
Initially, the mode of the class of 18 students is 83. This means that most of the students scored the 83 marks in the test. After four students took the test, the maximum probability that the mode will remain 83 is the highest. Also, one of the four numbers scored 83 itself.
Therefore, the maximum possible value for the new mode is 83.

What is the measure of angle of 1?
Answer:
m<1 = 118
Step-by-step explanation:
The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that
(28) + (90) = m<1
Remember, a box around an angle signifies that its measure is (90) degrees.
Solve this problem by performing the operation,
118 = m<1
