Helpppp ASAPS i need your help i give brainlist to the correct answer​​ only the question 2 and 3​

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.

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

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.

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.

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!

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]

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

[1/7 x - 1/5][(1/49 x²)+(1/35 x)+(1/25)]

(0.1b - 2)[0.01b²+0.2b+4]

Step-by-step explanation:

a³-b³=(a-b)(a²+ab+b²)

So

1/343 x³ - 1/125

[(1/7)x]³ - [1/5]³

[1/7 x - 1/5][(1/7 x)²+(1/7 x)(1/5)+(1/5)²]

[1/7 x - 1/5][(1/49 x²)+(1/35 x)+(1/25)]

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%

Answer:

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.
