Step-by-step explanation:
We have to list the elements present in each set.
A = {multiples of 3 between 20 and 32}
A = {21, 24, 27, 30}
B = {odd numbers between 20 and 32}
B = {21, 23, 25, 27, 29}
C = {even numbers between 20 and 32}
C = {20, 22, 24, 26, 28, 30, 32}
a) list the members of A ∪ B
This means to select the elements of sets A and B
A ∪ B = {21, 23, 24, 25, 27, 29, 30}
b) list the members of A ∩ C
This means to only pick the elements that are present in both A and B
A ∩ C = {24, 30}
The length of a rectangle is 5 yd less than twice the width, and the area of the rectangle is 33 yd?. Find the dimensions of the rectangle.
Answer:
Step-by-step explanation:
L=2W-5
A=LW, using L from above gives you
A=(2W-5)W
A=2W^2-5W
2W^2-5W-A=0, since A=33yd^2
2W^2-5W-33=0
2W^2+6W-11W-33=0
2W(W+3)-11(W+3)=0
(2W-11)(W+3)=0, since W>0
W=11/2
W=5.5yd, since L=2W-5
L=6yd
So the dimensions are W by L, 5.5yd by 6yd
Elizabeth bought 8 chicken wings for $10.40. How much does each wing cost?
Answer:
$1.30
Step-by-step explanation:
If 8 chicken wings is $10.40, to find the amount per chicken wing $10.40 gets divided by 8.

Step-by-step explanation:
if you you have x2 and 10 subtract
x2-10 this is because 2 x 5 is 10
very sorry if wrong
Answer:
b. x²-10
Step-by-step explanation:
Area of the whole square: x² because x*x = x²
area of unshaded area: 5*2 = 10
so shaded area: area of whole square - area of unshaded area
x² - 10
Christina Fox took out a simple interest loan at 5 percent for 12 months. Her previous balance is $200. What is the interest for the next payment?
a. $0.83
b. $0.99
c. $0.59
d. $1.37
Answer:
a. $0.83
Step-by-step explanation:
Calculation for the interest for the next payment
Using this formula
Next payment Interest=Previous balance*Simple interest loan percentage/Numbers of months
Let plug in the formula
Next payment Interest=$200*0.05/12
Next payment Interest=0.83
Therefore the interest for the next payment will be 0.83
Answer:
the answer is "A. $0.83........9x + 3y = 6 and 3x + 9y = 6

Find the volume of the cone.
13 cm
n = 9 cm
Answer:
V = 1102.7 cm^3
Step-by-step explanation:
1. Volume of Cone Formula
[tex]V=\frac{1}{3}*h*\pi *r^{2}[/tex]
2. Variables: h = 13 cm r = 9 cm
3. Plug in numbers
[tex]V=\frac{1}{3}*13*\pi *9^{2}[/tex]
V ≈ 1102.69 cm^3

Answer:
2) 3 : 15 = 1 : 5
3) 22 : 38 = 11 : 19
4) 2 : 5 = 26 : 65
Step-by-step explanation:
2) 5, 3, 1, 15
3 : 15 = 1 : 5
If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.
3) 19, 22, 11, 38
22 : 38 = 11 : 19
If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.
4) 65, 2, 26, 5
2 : 5 = 26 : 65
If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.
Hope this helps and stay safe, happy, and healthy, thank you :) !!
Consider the glven solids with the dimensions shown. Which solids are similar?
A. only figure 1 and figure 2
B. only figure 1 and figure 3
C. only figure 2 and figure 3
D. all three figures
Answer:
A) only figure 1 and figure 2
Step-by-step explanation:
Answer: Choice A) only figure 1 and figure 2
===========================================================
Explanation:
Let's assume that figure 2 is similar to figure 3.
If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.
Figures 2 and 3 cannot be similar for that reason.
Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.
We eliminate answers B, C and D. The only thing left is choice A.
-------------------
To verify choice A is true, we divide each corresponding piece like so
Horizontal: 15/10 = 1.5Vertical: 24/16 = 1.5Slanted: 12/8 = 1.5Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.

Answer:
[tex]y=-2\\[/tex]
Step-by-step explanation:
Use the values of the unit circle to get the (x,y) when Θ=[tex]\frac{11\pi}{6}[/tex], which is [tex](\frac{\sqrt{3}}{2}, -\frac{1}{2})[/tex].
The cosecant (csc) function is the reciprocal of the sine function, so we take the y value and take the reciprocal of it, which is -2.

[tex](x - 7)(x - 5) = 3[/tex]
Answer:
x = 4, x = 8
Step-by-step explanation:
Given
(x - 7)(x - 5) = 3 ← expand factors using FOIL
x² - 12x + 35 = 3 ( subtract 3 from both sides )
x² - 12x + 32 = 0 ← in standard form
(x - 4)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 8 = 0 ⇒ x = 8
Graph the inequality on a number line z<1 1/4
Answer:
Step-by-step explanation:
The inequality can be seen graphed in the number line that I have created in the attached picture below. As you can see the open circle represents the value 1 1/4 and is an open circle because it is not included in the inequality. This is because the variable z is less than but NOT equal to 1 1/4. Also since z is any number less than 1 1/4 then the number line goes towards negative infinity.

Sandeep uses 1/5 of a cup of vinegar in his salad dressing recipe. How much vinegar would Sandeep use to make 4/5 of a recipe?
Answer:
4 /25
Step-by-step explanation:
Given that :
Cup of vinegar used per recipe = 1/5 cup
Amount of vinegar to be used for 4/5 of a recipe ;
1 cup recipe = 1/5 cup vinegar
4/5 cup recipe = x
Cross multiply :
x = 1/5 * 4/5
x = 4/25 cup
Hence, Sandeep will use 4/25 cup of vinegar
