See belowStep-by-step explanation:
#14Given:
m∠QPT = 42° and PR is its angle bisectorAngles QPR and TPR both are:
42/2 = 21°Verify if the remaining angles are same.
m∠PQR = 180° - 21° - 58° = 101°This is not same as ∠PTS:
101° ≠ 102°This makes ∠PST ≠ ∠PRQ
Since corresponding angles are different, the triangles are not similar
#16Given two right triangles.
Verify the corresponding sides have same ratio.
Find the ratio of longer legs:
LN/MN = 15/27 = 5/9Find JN:
JN = √(JM² - MN²) = √(30.6² - 27²) = √207.36 = 14.4Find the ratio of shorter legs:
LN/JN = 8/14.4 = 80/144 = 5/9The triangles are similar by SAS since we have two sides similar and included angle is same (right angle)

measure of angle ECD
Answer:
∠ECD = 82°
Step-by-step explanation:
Alternate Interior Angles Theorem : when two parallel lines are cut by a transversal, the alternate interior angles are congruent. Alternate angles form a Z shape and are sometimes called "Z angles".
Therefore,
∠CDF = ∠GBC = 45°
∠CEF = ∠GAC = 53°
The sum of the interior angles of a triangle is 180°
⇒ ∠ECD + ∠CDF + ∠CEF = 180
⇒ ∠ECD + 45 + 53 = 180
⇒ ∠ECD = 180 - 45 - 53 = 82°
In ∆ABC
m<C be x[tex]\\ \tt\longrightarrow x+53+45=180[/tex]
[tex]\\ \tt\longrightarrow x+98=180[/tex]
[tex]\\ \tt\longrightarrow x=180-98[/tex]

Now
m<ECD and m<ACB are opposite hence equal

help me with solving for x please
Hey there!
8x - 3 + 4x + 3 = 180°
COMBINE the LIKE TERMS
(8x + 4x) - (3 + 3) = 180°
8x + 4x - 3 + 3 = 180°
12x + 0 = 180°
12x = 180°
DIVIDE 12 to BOTH SIDES
12x/12 = 180/12
CANCEL out: 12/12 because that gives you 1
KEEP: 180/12 because it helps solve for the x-value
NEW EQUATION: x = 180/12
SIMPLIFY IT!
x = 15
Therefore, your overall answer is: x = 15
The answer to your given question is:
12x + 0 = 180
Good luck on your assignment & enjoy your day!

Adjust the equations to create three different parabolas that pass through the points.
Answer:
Make all of the +/-2 values into -3,+4
Step-by-step explanation:
This is because the x intercept values for a parabola are where the equation equals zero, by making the equations -3 and +4, the equations will give zero values at -4 and plus 3 when they are set equal to zero, I can specify further if need be.

By using the equivalence of the formed angles, the solution is x = 41.
How to get X?
Note that the angle that is at the right of the equation with x, is equivalent to the bottom right angle, which measures 60°.
Then we will have that:
(3x - 3)° + 60° = 180°
Now we can solve that for x:
(3x - 3)° = 180° - 60° = 120°
3x = 120 + 3
x = 123/3 = 41
The solution is x = 41

Hector used 438 cups of wheat flour and some corn starch to replace cake flour in a recipe that required 5 cups of cake flour. How much wheat flour is used to replace each cup of cake flour?.
Answer:
438/5 and some corn starch = 1 cup
so 87.6 of wheat flour cups for one cake flour cup
Step-by-step explanation:
1 cake flour=x
x=438/5
x=87.6 and some corn starch but it's not mentioned how much so we can just say 87.6 wheat flour cups for 1 cake flour.

Answer:
15m
Step-by-step explanation:
to answer this question, we need to use pythagorean theorem. this theory says:
a² + b² = c²
so, let’s work out b.
a² + b² = c²
20² + b² = 25²
20 x 20 = 400. 25 x 25 = 625.
400 + b² = 625.
we want to solve for b, which means to get b in it’s own, so we are going to get rid of the 400 on both sides, leaving just b² on the one side.
625-400=225.
b² = 225
b = √225
b = 15 :)

What is the percent of change from 60 to 87?
Answer:
45% increase
Step-by-step explanation:
The new number (87) is bigger than the original number (60), so this is a percent increase.
To find the percent of change, which in this case is a percent increase, take the change amount and divide by the original, then convert to a percent.
Subtract to find the change.
87 - 60 is 27.
27 is the amount of change.
change/original
= 27/60
= .45
Times by 100 to change to a percent.
.45 × 100
= 45%
The function f(x) = 1/x-3 is defined for all real numbers except when x equals

4) 3
lol
Answer:
except when x = 3
Step-by-step explanation:
f(x) = [tex]\frac{1}{x-3}[/tex]
the denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be.
x - 3 = 0 ⇒ x = 3 ← excluded value
f(x) is defined for all real numbers except when x = 3

Tom is throwing darts at a target. In his last 30 throws, Tom has hit the target 20 times. You want to know the estimated probability that exactly one out of the next three throws does not hit the target.
Categorize the simulations as correct or incorrect simulations of Tom’s scenario.
Each scenario can be used to simulate probability, and there are 3 correct scenarios and 2 incorrect scenarios in the list of options
How to categorize the simulations?From the question, we have the following parameters:
Number of throws = 30Number of hits = 20This means that the probability of hit is:
P(Hit) = 20/30
Simplify
P(Hit) = 2/3
Using the complement rule,
P(Miss) = 1/3
The above means that the simulation that represents the situation must have the following parameters:
P(Success) = 2/3P(Failure) = 1/3Number of experiments = 3Using the above highlights, the correct scenarios are:
Rolling a die three times with numbers 1 to 4 representing a hitSpinner a spinner of 3 equal sections three times with two sections representing hitSpinner a spinner of 6 equal sections three times with four sections representing hitRead more about probability at:

A student calculated the mean of a set of 15 numbers and gets a result of 41.6. In calculating the mean, he inadvertently entered 117 for one of the numbers into his calculator instead of 17. What is the true mean of the data
Answer:
35.93
Step-by-step explanation:
If the mean of 15 numbers is 41.6, the sum of these numbers must be (15)*(41.6) = 624
We n=know one of these numbers is the 117 that was entered by mistake. Subtract that out and replace it with the correct number, 17. In essence we are modifying the number by (-117+17) or -100.
524 is the corrected value. Divide that by 15 to find the ciorrect mean:

How many positive integers x satisfy the inequality x^2 + x < 100?
Answer:

Highest value of x is 9.
9^2 + 9 = 90.
Not sure if zero counts, but if it does, it'll be 10 numbers instead.

There are 9 positive integers x satisfy the inequality x² + x < 100.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the inequality
x² + x < 100.
First take x= 1 then
1² + 1 = 2 < 100
Take x= 2
2² + 2 = 6 <100
Take x= 3
3² + 3 = 12 < 100
Take x = 4
4² + 4 = 20 < 100
Take x= 5
5² + 5 = 30 < 100
Take x =6, 7, 8, 9, 10 and 11
6² + 6<100
7² + 7<100
8² + 8<100
9² + 9 <100
10² + 10 > 100

Answer:
2 mm: 1 m
Step-by-step explanation:
The scale drawing has the length of the soccer field as 232 millimetres.The actual field is 116 meters long.That is, the same soccer field has different lengths in actual and in a map.
These scale and actual lengths must be related, and they are related to each other by what we call the scale ratio.
Scale ratio = dimensions in a drawing : actual dimensions
= 232mm : 116m
(we divide this by 116 to get 2)
= 2mm : 1m
