Answer:
x=19
Step-by-step explanation:
●Alternate angles are equal
therefore, angle WYZ= angle YWX
2x= angle YWX
●Angles within a triangle sum up to 180 degrees
=3x-5+2x+90=180
▪︎group like terms
=3x+2x+90-5=180
=5x+85=180
▪︎send all x terms to one side of the equation
=5x=180-85
=5x=95
▪︎divide both side by the coefficient of x ; 5
=x=19
Zoe is doing a survey to find the time her classmates spend playing video games. She asks the following question:
Which student spends the most time playing video games?
Describe the data you would expect her to collect from this question. (5 points)
Answer:
Step-by-step explanation:
I would expect her to find out how long each classmate spends playing video games. Then, I'd expect her to use this information and put it into a bar chart so that she can compare the numbers and find the biggest one, or who spends the most time playing video games.
Here's a random example:
Let's say she has 4 classmates, Zoe, Robert, John, and Taylor.
Zoe: 2 hours on video games
Robert: 6 hours on video games
John: 1 hour on video games
Taylor: 4 hours on video games
Then, i'd put this information into a bar chart. The screenshot is a random reference of what a bar chart looks like.
Answer: just find how much time each one spent , put it on a chart and yh

A music shop sold twenty five $50.00 radios at a profit of 8% and six $30.00 radios at a loss of 15%. How much was the profit or loss on the combined transaction?
Answer:
Step-by-step explanation:
the original price would be $80.00
50.00*0.08 = 4 50.00-4 = 46.00
46.00 for 25 radios with 4 cash back
30.00*0.15= 4.5 30.00- 4.5 = 25.50

Work Shown:
C = circumference = 40 inches
d = diameter
[tex]C = \pi*d\\\\C \approx 3.14*d\\\\40 \approx 3.14*d\\\\\frac{40}{3.14} \approx d\\\\d \approx \frac{40}{3.14}\\\\d \approx 12.73885\\\\d \approx 13\\\\[/tex]
Be careful. Technically 12 inches is the largest diameter Tanya can use since 3.14*12 = 37.68 is under 40; while 3.14*13 = 40.82 is slightly over 40
So if I was the teacher, I would have said "round down to the nearest inch".

Answer:
[tex]\sf a. \quad \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]
Step-by-step explanation:
Formula for calculating speed:
[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]
Therefore:
[tex]\boxed{\sf Time=\dfrac{Distance}{Speed}}[/tex]
Given values:
x = the current (in mph)Speed = 10 mphDistance = 21 milesTotal time = 5 hoursIf the boat is traveling downstream, the current (x mph) will be pushing the boat faster, and so the boat's speed will increase by x mph.
Therefore, the expression for the time it takes for the boat to travel downstream is:
[tex]\sf Time\:(downstream)=\dfrac{21}{10+x}[/tex]
If the boat is traveling upstream, the current (x mph) will be pushing against the boat and so the boat's speed will decrease by x mph.
Therefore, the expression for the time it takes for the boat to travel upstream is:
[tex]\sf Time\:(upstream)=\dfrac{21}{10-x}[/tex]
Therefore, if the total time it takes to travel downstream and upstream is 5 hours:
[tex]\implies \sf \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]
To solve for x:
[tex]\implies \sf \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]
[tex]\implies \sf \dfrac{21(10-x)}{(10+x)(10-x)}+\dfrac{21(10+x)}{(10-x)(10+x)}=5[/tex]
[tex]\implies \sf \dfrac{21(10-x)+21(10+x)}{(10+x)(10-x)}=5[/tex]
[tex]\implies \sf21(10-x)+21(10+x)=5(10+x)(10-x)[/tex]
[tex]\implies \sf 210-21x+210+21x=5(100-10x+10x-x^2)[/tex]
[tex]\implies \sf 420=500-5x^2[/tex]
[tex]\implies \sf 5x^2=80[/tex]
[tex]\implies \sf x^2=16[/tex]
[tex]\implies \sf x=\pm4[/tex]
Therefore, the rate of the current is 4 mph.

Answer:

Step-by-step explanation:
Definitions
Integer: a whole number that can be positive, negative or zero.The sum of three consecutive even integers
Let x be the first even integer.
As there is a difference of 2 between consecutive even integers, the next even integer after x will be (x + 2).
Therefore, the next even integer after (x + 2) will be (x + 2) + 2 = (x + 4).
So "the sum of three consecutive even integers is twenty-six" is:
x + (x + 2) + (x + 4) = 26
To solve
⇒ x + (x + 2) + (x + 4) = 26
⇒ x + x + 2 + x + 4 = 26
⇒ 3x + 6 = 26
(Please note that there are no three consecutive even integers that sum to 26, so the problem cannot be solved).
List three solutions for the inequality x ≤ 3 and give three

Not:

1921131
Step-by-step explanation:
x needs to be equal or less than 3. It doesn't say that x cannot be negative so any number 3 and below is fine.
Not solutions would be any number above 3 in value
The three solutions for the inequality are 1, 2, and 3.
And, the three numbers that are not solutions are 4, 5, and 6.
Used the concept of inequality that states,
A relation by which we can compare two or more mathematical expressions is called an inequality.
Given that,
The inequality is,
x ≤ 3
Now from the given inequality x ≤ 3,
The solution of the inequality is a number that is less or equal to 3.
Hence the possible three solutions for the inequality are,
x = 1, 2, 3
And, the three numbers that are not solutions are,
4, 5, and 6.

A batch of cookies is 24 cookies. It cost Courtney 134 dollars and 40 cents to make 10 batches of cookies.
How much does it cost Courtney to make 1 batch of cookies? Round to tenths places if necessary.
How much does it cost her to make 1 cookie? Round to the tenth place if necessary.
Answer:
13 dollars and 44 cents, 56 cents.
Step-by-step explanation:
134 dollars are 40 cents = 134.4 dollars.
10b = 134.4
b = 13.44
13 dollars and 44 cents
There are 24 cookies to a batch
24c = 13.44
c = 0.56.
so each cookie costs 56 cents
Answer:
13.44 to make 1 batch. 0.56 to make 1 cookie.
Step-by-step explanation:
If it cost 134.40 to make 10 batches, then you would divide that by 10 for how much it cost for 1 batch.
Then, 1 batch of 24 costs 13.44, you would divide it by 24 for the cost of 1 cookie.

Using it's concept, there is a 0.6667 = 66.67% probability of getting a total of 13 or more.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
From the tree diagram, there are 9 outcomes, of which 6 result in a total(first node + second node) of 13 or more, hence the probability is:

Answer:
38 degrees
Step-by-step explanation:
Since angles KLO and OLM are supplementary, they add up to 180 degrees
So, angle OLM is 180-134=46 degrees
Similarly, angles OMN and OML are supplementary, so they also add up to 180 degrees
So, angle OML is 180-84=96 degrees
You also know that the angles of a triangle sum up to 180 degrees
So, 46+96+x=180
180-142=38
x=38 degrees

We have proven that ΔACO ≅ ΔBDO using the SAS (Side-angle-side) theorem
Congruent trianglesFrom the question, we are to prove that ΔACO ≅ ΔBDO
From one of the congruent triangles theorem, we have that
If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
This is the SAS (Side-angle-side) theorem.
From the given information,
AB and CD intersect at point O
Thus, AO = BO
Also,
∠ACO ≅ ∠BDO
In the diagram, we can as well observe that CO ≅ DO
Thus, we can conclude that AC ≅ BD
Since sides AC, CO and the included angle ACO are congruent to sides BD, DO and the included angle BDO, we can conclude that ΔACO ≅ ΔBDO using the SAS theorem.
Hence, we have proven that ΔACO ≅ ΔBDO

Answer: Both C and D are correct
Step-by-step explanation:
To remove the exponent from the v you need to square root both sides,
the exponent on the v is then canceled out giving you:
[tex]v=\sqrt{25/81}[/tex] or [tex]v=-\sqrt{25/81}[/tex]
Answer:
Both C & D are correct
Step-by-step explanation:
[tex]v^{2} =\frac{25}{81}[/tex]
Root both sides of the equation to remove the square.
[tex]v=\±\sqrt{\frac{25}{81} }[/tex]
[tex]v = \±\sqrt{\frac{5*5}{9*9} } \\v=\±\frac{5}{9}[/tex]
Therefore,
[tex]v=\sqrt{\frac{25}{81} } =-\sqrt{\frac{25}{81} }[/tex]
