I need help solving the value for x and y​

Answer:

4) [tex]3\sqrt{3}[/tex] 5) [tex]10\sqrt{18}[/tex]

Step-by-step explanation:

[tex]27[/tex] can be broken down into [tex]3[/tex] and [tex]9[/tex]

[tex]\sqrt{27}=[/tex][tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]

However, [tex]\sqrt{9} =3[/tex], so its really just:

[tex]3\sqrt{3}[/tex]

[tex]1800[/tex] can be broken down into [tex]100[/tex] and [tex]18[/tex]

[tex]\sqrt{1800} =[/tex][tex]\sqrt{100}[/tex] × [tex]\sqrt{18}[/tex]

However, [tex]\sqrt{100} =10[/tex], so it is really:

[tex]10\sqrt{18}[/tex]

Answer:

No.

Step-by-step explanation:

If she is riding 15 miles per hour (the rate), and she has six hours (the time), then in order to find out the distance, we multiply the rate*the time.

15*6 = 90

90<96

So, no, she will not make it.

Answer:

8,107,424

Step-by-step explanation:

We have an expanded form of a number and are asked to convert it into standard form.

We always have to look at the place value when it comes to expanded form.

So follow the place values :

Million , Hundred Thousand, Ten Thousand, Thousand, Hundred, Tens, Ones.

1,000,000, 100,000, 10,000, 1,000, 100, 10, 1

Look at the values given and replace it

8,000,000, 100,000, 0, 7,000, 400, 20, 4

Now add them all :

8,107,424

Answer:

60%

Step-by-step explanation:

If 20 quarts of 15% garlic is mixed with 45 quarts 80% garlic, what percent garlic is the new mixture?

Let us represent:

15% garlic = x

80% garlic = y

Total quarts of the new mixture =

20 + 45 = 65 quarts

Hence:

15% × 20 + 80% × 45 quarts = 65quarts(x%)

3 + 36 = 65 × x%

39 = 65 × x%

x % = 39/65

x% = 0.6

Converting to decimal

= 0.6 × 100

= 60%

The Percent of the new garlic mixture = 60%

Answer:

Let andre score be x points.

then Diego's score will be (x-9) points.

Noah's points=2(x-9) points

the equation is 2(x-9) = 10

dividing both sides by 2,

2(x-9)/2 =. 10/2

x-9= 5

adding 9 both sides,

x-9+9= 5+9

x=14.

Step-by-step explanation:

Answer:

Andre score 14 points

Step-by-step explanation:

noah = 2*diego

diego = andre - 9

given noah = 10

noah = 2*Diego

10 = 2*Diego

Diego = 5

diego = andre - 9

5 = andre - 9

andre = 9 + 5

Andre = 14

Answer:

C.

Step-by-step explanation:

This is correct because the triangles are similar. Angle S is similar to Angle Y, and Angle R is similar to Angle X.

None of the others can be correct either.

Answer:

look at the explanation

Step-by-step explanation:

hey hey. i’ll help you. sorry if this is long. :)

okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.

now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.

18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5

okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!

$3160.20 + $553.50 = $3713.70

so in a week, she makes $3713.70

i hope this helped you! good luck!

Step-by-step explanation:

i did it on the question thing comments. And I’m super positive it’s right.

Given:

The table of values for Fallon's earnings in terms of Donald's earnings.

To find:

The equation that best represents Fallon's earnings in terms of Donald's earnings.

Solution:

In the given table the x-values are increasing by 5 units and  y values increasing by 5 units. It means the rate of change of y with respect to x is constant and the table represents a linear function.

If the graph of a linear function passes through two points, then the equation of linear function is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Consider any two points from the table. Let the two points are (38,45) and (43, 50). Then, the equation is

[tex]y-45=\dfrac{50-45}{43-38}(x-38)[/tex]

[tex]y-45=\dfrac{5}{5}(x-38)[/tex]

[tex]y-45=1(x-38)[/tex]

[tex]y-45=x-38[/tex]

Adding 45 on both sides, we get

[tex]y=x-38+45[/tex]

[tex]y=x+7[/tex]

Therefore, the correct option is A.

Answer:

If the scale factor of corresponding sides is 1:2 then the hypotenuse if 50 units.

Step-by-step explanation:

The length of the hypotenuse of the larger triangle is 50 units.

Scale factor is a mathematical term, which we use to scale 2-dimensional and 3-dimensional shapes.

For example, Two spheres look similar but could have different radii.

Let's denote the length of the hypotenuse of the smaller triangle as c, and the length of the hypotenuse of the larger triangle as C. Then we can write:

C/c = 2/1

Multiplying both sides by c, we get:

C = 2c

We can use the Pythagorean theorem to find the length of the hypotenuse c of the smaller triangle:

c² = 15² + 20²

c² = 225 + 400

c² = 625

c = 25

Substituting c = 25 in the equation above, we get:

C = 2(25)

C = 50

Therefore, the length of the hypotenuse of the larger triangle is 50 units.

Step-by-step explanation:

Your welcomeee

Answer:

1. a

2. c

3. a

4. b

Step-by-step explanation:

1. Factor 15x + 35 using the GCF

The GCF (Greatest common factor) between these two numbers is 5. In other words, both 15x and 35 can be divided by 5. So if you divide both by 5 and then multiply it by 5, you will get 5(3x + 7), or "a".

2. Which expression is equivalent to -5(x + 10)?

Multiply the x and 10 by -5. You will get -5x - 50, or "c"

3. Subtract (8x + 6) - (x + 4)

Multiply the second parentheses by -1 (because there is a subtraction sign in front of it. This is the same as + (-1)), and then open the parentheses.

8x + 6 - x - 4

7x + 2, or "a"

4. Add (11x + 2) + (9x - 4)

Open the parentheses

11x + 2 + 9x -4

20x -2, or "b"

Hope this helps! Feel free to ask any questions! :)
