Evaulate 9÷3[(20-7) -2to the power of 2]
Answer:
27
Step-by-step explanation:
Evaulate 9÷3[(20-7) -2to the power of 2]
9÷3[(20-7) - 2²]
9 ÷ 3 = 3
[(20-7) - 2²] = (13 - 4) = 9
Hence ;
9÷3[(20-7) - 2²]
3(9)
= 27

4 cups=1 quart
Capacity: 5x4+2=22 cups
Right now 1x4+3=7
22-7=15 cups
12/4 +3
3 quarts and 3 cups more
Rewrite the given parametric equations in Cartesian from x(t) = 2t– 1 y(t) = 5t
Hi there!
[tex]\large\boxed{(-\frac{5}{3},-\frac{5}{3})}[/tex]
We can begin by setting the two expressions equal to solve for t:
2t - 1 = 5t
Subtract 2t from both sides:
-1 = 3t
Divide both sides by 3:
t = -1/3
Plug in this value of t into x(t) and y(t):
x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3
y(-1/3) = 5(-1/3) = -5/3
Thus:
(-5/3, -5/3) are the corresponding coordinates.

What is the real part of this complex number :
2i^28 - 3i^25
Answer:
(2*1)²⁸-(3*2*1)²⁵
=-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.
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%
The lateral area of a cone is 558 pi cm^2. The radius is 18 cm. Find the slant height to the nearest tenth
Answer:
31.
Step-by-step explanation:
π(18)l = 558π
l = 558/18 = 31
Therefore the answer is 31.
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

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
Is there a unique triangle with angle measures
of 30°, 60°, and 90°?
In the diagram belowthe length of segment AB is 10, the length of segment AD is 25, and the length of segment AEis 20. What is the length of segment AC? A. 6 B. 10 C. 5 D. 8
The image of the triangle is missing, so i have attached it.
Answer:
Option D: 8
Step-by-step explanation:
We are given;
AB = 10
AD = 25
AE = 20
We want to find length of AC.
By proportion, we can find length of AC. Thus;
AB/AD = AC/AE
Plugging in the relevant values, we have;
10/25 = AC/20
AC = (10 × 20)/25
AC = 8
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.

Step-by-step explanation:
The sum of the angles of a triangle is 180
Let the unknown angle be x
94+45+x = 180
Combine like terms
139 +x = 180
Subtract 139 from each side
139+x-139= 180-139
x =41
calculate the area of the following composite figure.
Answer:
85 cm²
Step-by-step explanation:
Solve the area of the Rectangle:
A = bh
10 × 6 = 60 cm²
Solve the area of the Triangle:
A = bh × 1/2

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.

If A is a 2x2 matrix and B is a 2x1 matrix, what is the dimension of AB?
Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix
