Step-by-step explanation:

x + 4y = 30

x – 2y=0

x= 2y

2y + 4y = 30

6y = 30

y = 5

x = 10

Answer:

[tex]\sqrt{30}[/tex]

Step-by-step explanation:

i assume this is the question you asked me to look at.

Well, angle 116° and y are supplementary angles

therefore,116°+y=180°

y=180°-116°=64°

Now to find x

x+y+125+72=360°

x+64+125+72=360

x+261=360

x=360-261=99°

The measure of x° is  99° and the measure of y° is 64°.

What is quadrilateral?

A quadrilateral is a polygon with four sides four angles and four vertices. Whenever we name a quadrilateral, we need to keep in mind the order of the vertices.

From the given figure,

116°+y°=180° (Sum of adjacent angles is 180°)

y°=180°-116°

y°=64°

Sum of interior angles of quadrilateral is 360°.

Here, x°+y°+72°+125°=360°

x°+64°+72°+125°=360°

x°+261°=360°

x°=99°

Therefore, the measure of x° is  99° and the measure of y° is 64°.

Answer:

Cassie bought 0.375 pounds of peanuts and 0.250 pounds of cashews, that is, she bought 50% more peanuts than cashews.

Step-by-step explanation:

Since Cassie bought 3/8 of a pound of peanuts and 1/4 of a pound of cashews, to determine the comparison between both nuts the following calculation must be performed:

3/8 = pounds of peanuts

0.375 = pounds of peanuts

1/4 = pounds of cashews

0.250 = pounds of cashews

Therefore, Cassie bought 0.375 pounds of peanuts and 0.250 pounds of cashews, that is, she bought 50% more peanuts than cashews.

Answer:

(a) [tex]x^4 * (-y)^4 = (xy)^4[/tex]

Step-by-step explanation:

Given

[tex]x^4 * (-y)^4[/tex]

Required

Select and equivalent expression

[tex]A.\ (xy)^4[/tex]     [tex]B.\ (-xy)^4[/tex]   [tex]C.\ -(xy)^4[/tex]    [tex]D.\ (x-y)^4[/tex]

[tex]x^4 * (-y)^4[/tex]

Apply law of indices:

[tex]x^4 * (-y)^4 =x^4 * (-y) * (-y) * (-y) * (-y)[/tex]

This gives:

[tex]x^4 * (-y)^4 = x^4 * (y) * (y) * (y) * (y)[/tex]

[tex]x^4 * (-y)^4 =x^4 * y^4[/tex]

x and y have the same exponent; So, they can be expressed as:

[tex]x^4 * (-y)^4 = (x*y)^4[/tex]

[tex]x^4 * (-y)^4 = (xy)^4[/tex]

Step-by-step explanation:

8^2 +12^2 = hyp ^2

64 +144 = hyp^2

208 =hyp ^2

Hyp = 4 root 13

x = sqaureroot of ( 18^2 + (4 root 13)^3)

x = sqaureroot of (324 +208)

x = sqaureroot of 532

x = 2 root 133

x = 23.065

x = 23

Answer:

x = 7

Step-by-step explanation:

[tex]\frac{10}{8} = \frac{3x-6}{12}[/tex] --> Triangle Similarity Theorem

120 = 8(3x - 6) --> Cross Multiplying

120 = 24x - 48 --> Distributing the 8

24x - 48 + 48 = 120 + 48 --> Adding 48 on both sides

24x = 168 --> Simplifying

24x/24 = 168/24 --> Divide 24 on both sides

x = 7 --> Simplifying

Answer:

25 bottles

Step-by-step explanation:

2 litres=2000 milliliters

2000/80=25 (or) 80x25=2000

The amount of containers it will take to fill the 2-liter bottle is 25 containers.

Given the following data:

To determine the amount of containers it will take to fill the 2-liter bottle:

In this exercise, you're required to determine the amount of 80-milliliter containers that would be required to fill the 2-liter bottle.

First of all, we would convert the volume in liters to milliliter.

Conversion:

1 Liter = 1000 millimeters

2 Liter = 2000 millimeters

Now, we can find the amount of containers by using the formula:

[tex]Number\;of\;containers = \frac{Volume \;of\;bottle}{Volume \;of\;containers}[/tex]

Substituting the parameters into the formula, we have;

[tex]Number\;of\;containers = \frac{2000}{80}[/tex]

Number of containers = 25 containers
