Find all values of x that make the triangles congruent. Explain.
When x=___, AB=CD=___ and AC=BD= ___, which means that AB≅CD and AC≅BD, BC≅BC by the Reflexive Property of Congruence. So, the triangles are congruent by the SSS Congruence Theorem.
I got x=5, but I'm confused about the AB=CD=___ and AC=BD=___. Could someone explain?
Answer:
Yes, you were correct with x=5. AB=CD=25 and AC=BD=23
Step-by-step explanation:
You already have x=5.
The first question is AB=CD=__ so you can just look at AB and you see it says 5x. You just substitute in the 5 for the x because you already got that. 5 times 5 = 25 and there is your first answer.
AC=BD=__ is your next question and you just look at AC and see "5x-2" and substitute in the x again. So you'll have 5(5)-2 which is 25-2 and your answer will be 23.
Yes, it is correct with x=5.It comes AB=CD = 25 and AC = BD=23.
Given that,
X = 5.We need to find out the AB = CD, And AC = BD.Based on the above information, the calculation is as follows:
AB = CD
Here AB = 5x
= 5(5)
= 25
So AB = CD = 25
Now
AC = BD
Here
AC = 5x - 2
= 5(5) - 2
= 25 - 2
=23
So AC = BD = 23
Therefore we can conclude that Yes, it is correct with x=5.It comes AB=CD = 25 and AC = BD=23.

What is the area of shape B?
Answer:
my answer is incorrect
Step-by-step explanation:
Since the two shapes are similar, you can answer this question with a proportion.
[tex]\frac{12}{200} = \frac{15}{area} \\12area = 200*15\\area = \frac{200*15}{12} = 250[/tex]
Another way you could solve it is to find the percentage growth of the height of the area.
[tex]\frac{15-12}{12} = \frac{3}{12} = 25[/tex] percent growth.
We can multiply the area of A by 1.25 to find the area of B
[tex]200*1.25 = 250[/tex]

Suppose a stage for the Lunar New Year festival has a length of 24 feet and a width of 4x + 4 feet. If the area of the stage is 384 square feet, what is the value of x?
Answer:
The value of x is 3
Step-by-step explanation:
The stage is rectangular in shape.
The formula for area of a rectangle is:
Length × Width
Length = 24 feet
Width = 4x + 4 feet
Hence:
384 = (4x + 4) × (24)
384 = 96x + 96
Collect like terms
384 - 96 = 96x
288 = 96x
x = 288/96
x = 3
The value of x is 3

(2) The sum of angles in a quad is always 360.
Take line RST and you get the value of angle RSP as 180 - 110 which is 70. This is due to them being linear pairs. Angles formed by a straight line is always 180 degrees!
110 + x = 180
x = 70
Now for y
Since we found values for all the 3 angles, which are 140, 110, 70, the 4th one is gonna be the sum of all the 3 angles subtracted from 360
140 + 110 + 70 + y = 360
y = 360 - (140 + 70 + 110)
y = 50 <- That's the answer.
(2) 2 of the angles are already given. If you look, angle U is 90 degrees. That's what the sign represents.
Angle Q (In the quad) is going to be 180 - 110 (Linear pairs) = 70
Since we found 3 angles the 4th one (angle R) is going to be 360 - (90 + 50 + 70) which is 360 - 210 which is 150.
Since angle R in the quad is 150, due to linear pair property, 3x = 180 - 150
3x = 30
x = 30/3 = 10
x = 10 <- That's the answer :D
Carly has 20 coins of pennies and dimes. The value totals $0.92.How many of each coin is there?
Pennies: ____________________ Dimes: _______________________
9514 1404 393
Answer:
Pennies: 12Dimes: 8Step-by-step explanation:
The number of pennies will be 2 more than a multiple of 10. 2 pennies and 9 dimes is not enough coins. 12 pennies and 8 dimes is exactly enough.
__
This one is easy to figure by "trial and error," as there is only one trial that makes any sense.
If you want to figure it using an equation, it usually works well to let a variable represent the quantity of the higher-value coin. If d is the number of dimes, then 20-d is the number of pennies. The total number of cents is ...
10d +(20-d) = 92
9d = 72 . . . . . . . . . subtract 20
d = 8
20-d = 12
There are 8 dimes and 12 pennies.
Which of the following transformations has the same result as a rotation of 90º CW?
a. dilation of scale factor of 9
b. rotation of 270º CCW
c. reflection about a horizontal line
d. translation down and to the right

Answer:
with ur head dummy <3....
Answer:
x = 13
y = 12
Step-by-step explanation:
4x and 52 have to be equal because they are opposites on the same line. So because of this we can make a simple equation to find x.
4x = 52
divide both sides by 4 and you have x
x = 13
to find y on the other equation, since we know two of the angles, we can add up all three angles and make them equal to 180 (the sum of all angles on a triangle)
90 + 52 + (3y +2) = 180
first subtract 90 and 52 from both sides to leave the equation alone
3y + 2 = 38
second substract 2 to isolate the variable
3y = 36
lastly divide both sides by three
y = 12
The level of water in a draining pool can be modeled with the function d(t)=12(.72)^t, where d is the depth of water, measured in feet, and t is the amount of time it's been draining, measured in days. Inayah claims that the pool is draining at a rate of 1.36%per hour. Is she correct? Explain
Answer:
She is not correct, the claim is wrong
Step-by-step explanation:
Here, we want to check if a claim
made is correct
We can represent the exponential function as;
y = I( 1 - r)^t
So in this case;
1 - r = 0.72
r = 1 - 0.72
r = 0.28
This is same as 28%
So what this mean is that we expect a decrease of 28% per day
There are 24 hours on a day
So the decrease per hour will be 28%/24 = 1.167%
So as we can see the claim is wrong
The model of the level of water in a draining pool is an illustration of an exponential function.
Inayah's claim is incorrect, because the water drains at 28% per hour
The function is given as:
[tex]\mathbf{y = 12(.72)^t}[/tex]
An exponential function is represented as:
[tex]\mathbf{y = a(1 - r)^t}[/tex]
Where r represents the rate.
So, by comparison
[tex]\mathbf{1 - r = 0.72}[/tex]
Collect like terms
[tex]\mathbf{- r = 0.72 - 1}[/tex]
[tex]\mathbf{- r = -0.28}[/tex]
Multiply both sides by -1
[tex]\mathbf{r = 0.28}[/tex]
Express as percentage
[tex]\mathbf{r = 28\%}[/tex]
This means that, the water drains at 28% per hour
Hence, Inayah's claim is incorrect

A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 3700 seats. The students filled 52% of the seats in the theater. How many 6th graders went on the trip?
Answer: 1924
Step-by-step explanation:
Number if seats in the theater = 3700
Percentage of seats filled by students in the theater = 52%
The number of 6th graders that went on the trip will be gotten by multiplying 52% by 3700. This will be:
= 52% × 3700
= 52/100 × 3700
= 0.52 × 3700
= 1924
1924 students went on the trip
