These triangles are congruent by _____.
A. ASA
B. AAS
C. SSS
D. Not enough information
E. None of these
Answer:
A. ASA
Step-by-step explanation:
The point in which they are connected is equal on both sides, it is an even 90-degree angle. The two lines indicate that the side is equal on both triangles and the red curve indicates that the angle is equal on both triangles. So it is congruent by ASA.
Jonathan draws a ticket from a box to select the door prize winners at a party. The tickets are numbered from 1 to 25. What is the expected value that the tickets drawn will have numbers less than 5 if he draws tickets 40 tickets
Answer:
6
Step-by-step explanation:
Given that there are tickets in the draw which are numbered from 1 to 25.
Probability of an event E is given by the formula:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Probability of each number can be found out as:
Number of favorable cases for each number is 1 and total number of cases here is equal to the total number of tickets i.e. 25.
[tex]P(Each\ Number) = \dfrac{1}{25}[/tex]
Now, the numbers less than 5 mean 1, 2, 3 and 4.
Therefore, 4 number of favorable cases.
[tex]P(1, 2, 3\ or\ 4) = \dfrac{4}{25}[/tex]
Now, it is given that 40 tickets are drawn.
Number of times, the numbers less than 5 are expected:
[tex]\dfrac{4}{25}\times 40 \approx 6[/tex]

Which one is the answer to it
Answer:
- 6 and - 4
Step-by-step explanation:
Given
- [tex]\frac{1}{2}[/tex] x + 4 ≥ 6 ( subtract 4 from both sides )
- [tex]\frac{1}{2}[/tex] x ≥ 2
Multiply both sides by - 2 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.
x ≤ - 4
The only values from the set which satisfy the inequality are
- 4 and - 6
The radius of the puddle is zero when time is zero but expands at a rate of one-quarter unit per second instead of one-half unit per second. By what factor does the denominator of the resultant composite function A(r(t)) change from that in the opening scenario?
Given that the radius of the puddle expands, originally, at a rate of 1/4 unit/second instead of 1/2 unit/second.
The current rate of expension of the radius,
\frac {r(t)}{t}=frac 1 4 unit/second ...(i)
The resultant composite function is area, A(r(t)).
The area of a circular region having radius r is,
[tex]A(r)=\pi r^2[/tex]
If the radius is the function of time, then the composite function is
[tex]A(r(t))=\pi \(r(t))^2[/tex]
To determine the rate of change of area with respect to time, differentiate the composite function A(r(t)) once with respect to time, we have
[tex]\frac {d\{A(r(t))\}}{dt}=\pi \left(2\frac {d\{r(t)\}}{dt}\right)[/tex]
So, the composite function is changing twice of the rate of change of the radius.
By using equation (i), if r(i) is changing with R= 1/4 unit / second.
Then, A(r(t)) will change 2 x 1/4 = 1/2 square unit/second.

Amanda buys some back-to-school clothes. She buys three T-shirts at $9.00 each, two pairs of jeans at $20.00 each, and five pairs of socks at $3.50 each. What is the total cost of her purchases?
Answer:
the correct answer is 84.5$
Step-by-step explanation:
The way how i got this because 3*9 for the t shirts
2*20 for the jeans
and 5*3.50 for the socks
Answer:
$84.50
Step-by-step explanation:
So we know she buys 3 nine dollar shirts
$9.00 times 3 shirts is $27.00
She also buys two pairs of jeans
$20.00 times 2 is $40.00
Finally she buys 5 pairs of socks
$3.50 times 5 is 17.50
so lets add it all up
27.00
40.00
17.50
=84.50

Lily sold 5 purses in her first week of business and 15 purses in her second week of business.If p represents the profit she makes from selling one purse, how could lily write and simplify a variable expression that represents her current profit after two weeks in business?
Answer:
20p = x
Step-by-step explanation:
Since Lily sold 5 purses in week one and 15 purses in week two that adds up to be a total of 20 purses sold in two weeks. Since p represents the profit for each purse she can use the expression below which simply multiplies the profit per purse (p) by the total amount of purses sold in the two weeks which would give her the total amount of profit (x) that she made from all of her sales.
20p = x
8 + 2r = −10 what is r?
Answer:
r = -9
Step-by-step explanation:
Subtract 8 from both sides to get 2r = -18. Divide by 2 on both sides to get r = -9.
Answer:
r=-9
Step-by-step explanation:
Step 1:- Simplify both sides of the equation.
2r+8 = -10
Step 2:- For isolating the variable, subtract 8 from both sides.
2r+8-8 = -10-8
2r = -18
Step 3:- For isolating the variable, divide by 2 from both sides.
2r/2 =-18/2
r= -9

Darius is building a square launch pad for a rocket project. If the area of the pad is 121 square centimeters, what is it's sides length? Use the area formula, A=s^2, and show your work.
Answer:
11 cm
Step-by-step explanation:
A = [tex]s^{2}[/tex]
Known that A = 121 [tex]cm^{2}[/tex],
121 [tex]cm^{2}[/tex] = [tex]s^{2}[/tex]
s = [tex]\sqrt{121}[/tex] cm = 11 cm
Done :)
The side length of a square launch pad is 11 centimeter.
Here,
Darius is building a square launch pad for a rocket project.
The area of the pad is 121 square centimeters.
We have to find, it's side length.
What is Area of square?
The area of a square = side x side
Since each side of a square is the same, it can simply be the length of one side squared.
Now,
The area of the pad is 121 square centimeters.
We use the area formula,
⇒[tex]A = s^{2}[/tex]
⇒ [tex]s^{2} = 121[/tex]
⇒[tex]s = \sqrt{121}[/tex]
⇒ [tex]s = 11[/tex]
Hence, The side length of a square launch pad is 11 centimeter.

Given the function f(x) = 2 x + 61 – 4, for what values of x is f(x) = 6?
Answer:
x = -51/2
Step-by-step explanation:
f(x) = 2x + 61 - 4
Since we are looking for the values where f(x) = 6, replace f(x) with 6 in the equation:
6 = 2x + 61 -4
Next combine like terms:
6 = 2x + 57
Then move subtract 57 from both sides to isolate the variable:
-51 = 2x
Finally, divide both sides by two to get x by itself:
x =-51/2
Answer:
69
Step-by-step explanation:
Replace x with 6.
2(6) =12 +61= 73-4=69

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.
If a point X(x, y) is reflected about the y = x line, the new location is X'(y, x)

Answer:
-10, 10
Step-by-step explanation:
To do that, we can set up an equation:
[tex]8x^2-800=0[/tex]
We can divide both sides by 8 to make it easier to solve:
[tex]x^2-100=0[/tex]
Now, isolate the x and take the square root of both sides:
