given: y is the midpoint of XZ
prove: XY 1/2XZ
Given:
Y is the midpoint of XZ.
To prove:
[tex]XY=\dfrac{1}{2}XZ[/tex]
Proof:
It is given that Y is the midpoint of XZ. It means Y divides the line segment XZ in two equal parts XY and YZ.
[tex]XY=YZ[/tex] ...(i)
Point Y lines on the segment XZ, so by segment addition theorem, we get
[tex]XY+YZ=XZ[/tex]
[tex]XY+XY=XZ[/tex] [tex][Using (i)][/tex]
[tex]2XY=XZ[/tex]
Divide both sides by 2.
[tex]XY=\dfrac{1}{2}XZ[/tex]
Hence proved.
Greg drove 300 miles at a constant speed in 5. The speed limit was 70 miles per hour. Was his rate greater than the speed limit?
The average speed of Greg will be 60 miles per hour.
To answer this question, we need to calculate Greg's average speed during the trip.
We can use the formula:
Average Speed = Total Distance / Total Time
In this case, Greg drove 300 miles in 5 hours, so:
Average Speed = 300 miles / 5 hours = 60 miles per hour
Since Greg's average speed was 60 miles per hour, which is less than the speed limit of 70 miles per hour, his rate was not greater than the speed limit.

Jack and Jill went to Taco Bell. Jack bought three tacos and two burritos
and paid $5.40. Jill bought two tacos and one burrito and paid $3.10.
What is the individual cost of a taco? How much does a burrito cost?
(How do I write my two equations for this?? Pls and thank you!)
answer:
x = 0.80
y = 1.50
step-by-step explanation:
x = cost of tacos
y = cost of burritos
both equations:
3x + 2y = 5.40
2x + 1y = 3.10
^
turn this | into this |
v
y = 3.10 - 2x
then add it to the equation :
3x + 2 [ 3.10 - 2x ] = 5.40
3x + 6.2 - 4x = 5.40
-1x = - 0.8
x= 0.80
then add x = 0.80 to the equations to get :
3 [ 0.80 ] + 2y = 5.40
2.4 + 2y = 5.40
2y = 3
y = 1.5

4-5)?
Answer:
12
Step-by-step explanation:
you would need to use BODMAS to work this out
as a result you would work out the value in the brackets which would equal to -1 so the question would look like this: 10-2(-1)
next you would do the multiplication due to the fact it comes next in the order
so you would end up with 10+2 which would equal to 12
Hope this helps
Answer:
12
Step-by-step explanation:
First we do 4-5 because of Order of Operations. So we get -1
Then we do multiplication because of Order of Operations and we get -2*-1=2
So now we do 10+2 and we get 12.
You may be asking why I did -2*-1.
It honestly doesn't matter.
Let's say I did 2*-1. We get -2.
Then we do 10-(-2) and If you subtract a negative, it's just adding basically. So we can put it as 10+2 and we get 12.

Henry predicted whether he got answers right or wrong in his 50 question exam. He identified the 36 questions he thought he got right. It turns out that Henry got 5 questions wrong that he thought he got correct and he only got 11 of the questions wrong he had predicted. What is the percentage accuracy he had with predicting his scores?
Answer:
84%
Step-by-step explanation:
Henry completed a total of 50 questions. From these 50 he predicted 36 were right and this means he also predicted that 14 were wrong (50-36 = 14). From these predictions 5 out of 36 from the ones that he predicted were right were actually wrong and 3 of the 14 questions (14-11 = 3) he predicted were wrong were actually right. Meaning in total he wrongly predicted 8 questions which means he predicted 42 correctly ...
42 / 50 = 0.84 = 84%
Therefore, Henry's prediction accuracy is 84%

After school one night, I had to stop at the local office supply store and pick up a few items. I bought 2 packages of page dividers. They each cost $3.79. I bought one package of Post-It Tabs that cost $6.79. Finally, I bought a large binder for $11.99. Sales tax was 7.5% and I paid with a 50 dollar bill. How much change did I receive?
Answer:
$21.66
Step-by-step explanation:
Add up all of the costs
3.79 + 3.79 + 6.79 + 11.99 = 26.36
Then multiply by the sales tax
26.36 x 7.5% = 1.98
Add the total cost and the tax
26.36 + 1.98 = 28.34
Subtract 28.34 from 50
50 - 28.34 = 21.66
That is how much change you recieve after your purchase.
Solve for x.
Зxy = W
Answer:
[tex]\huge\boxed{x=\frac{W}{3y}}[/tex]
Step-by-step explanation:
If we have the equation [tex]3xy=W[/tex] and we want to solve for x, our goal is to isolate x one one side of the equation.
The question we have to ask ourself is ”What’s stopping x from being isolated?”
That would be the 3 and the y.
Since we’re multiplying x by the 3 and the y, we can divide both sides by the 3 and the y to get x isolated.
[tex]3xy \div 3y = w \div 3y[/tex]
[tex]x = \frac{W}{3y}[/tex]
Hope this helped!

A recipe for orange water says, "Mix 3 teaspoons yellow water with 1 teaspoon red water." For this recipe, we might say: "The ratio of teaspoons of yellow water to teaspoons of red water is 3:1 ." Write a ratio for 2 batches of this recipe and explain how you know it is equivalent to 3:1.
Answer:
The ratio of 2 batches of recipe is 6:2. Which is equivalent to 3:1 because if we multiply the ratio with same number it would give us equivalent ratio.
Step-by-step explanation:
When mix 3 teaspoon of Yellow water with 1 teaspoon of red water, we get ratio as 3:1
If we use 2 batches of recipe, the ratio is multiplied twice.
That's ratio of yellow water to red water is 3*2 :1*2 , which gives 6:2
But, if we simplify the ratio, by dividing both by common factor, we would get 3:1
That's [tex]\frac{6}{2} :\frac{2}{2}[/tex] simplified to 3:1
Which equation represents f(x)? f(x) = RootIndex 3 StartRoot x + 6 EndRoot + 1 f(x) = RootIndex 3 StartRoot x minus 6 EndRoot + 1 f(x) = RootIndex 3 StartRoot x + 6 EndRoot minus 1 f(x) = RootIndex 3 StartRoot x minus 6 EndRoot minus 1
Answer:
A.
Step-by-step explanation:
The equation that represents function f(x) is (a) [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
The original function is given as:
[tex]y = \sqrt[3]{x}[/tex]
First, the function is translated 6 units left.
The rule of this translation is:
[tex](x,y) \to (x +6,y)[/tex]
So, we have:
[tex]y = \sqrt[3]{x + 6}[/tex]
Next, the function is translated 1 unit up.
The rule of this translation is:
[tex](x,y) \to (x,y+1)[/tex]
So, we have:
[tex]y = \sqrt[3]{x + 6} + 1[/tex]
Express y as a function of x
[tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
Hence, the equation that represents f(x) is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
