Step-by-step explanation:

If you have anything else that has to do with donuts it goes straight to me.

Answer:

102 more donuts

Step-by-step explanation

when dealing with how much percent increase you multiply the amount by the percent in decimal form . So 850x0.12 is 102.

Answer:

y = 1/4x

Step-by-step explanation:

Answer:

25.2 in.

Step-by-step explanation:

Given:

RQ = 7 in.

QL = 24 in.

LK = 3 in.

Required:

Length of diagonal RK

Solution:

Apply the extension of the Pythagorean theorem which is:

d² = x² + y² + z²

Where,

d = RK

x = RQ = 7 in.

y = QL = 24 in.

z = LK = 3 in.

Plug in the values

d² = 7² + 24² + 3²

d² = 634

d = √634

d = 25.1793566 ≈ 25.2 in. (nearest tenth)

Answer:

[tex]x=100\\y=60[/tex]

Step-by-step explanation:

The shape of the figure is quadrilateral, that means overall it will be 360 degrees.....

Angle of straight line to find x:

[tex]x+80=180[/tex]

[tex]x=180-80[/tex]

[tex]x=100[/tex]

Now, both the values of x will be 100

Find the value of y:

[tex]y+100+120+80=360[/tex]

[tex]y+300=360[/tex]

[tex]y=360-300[/tex]

[tex]y=60[/tex]

Therefore, [tex]x=100[/tex] and [tex]y=60[/tex]

hope this helps, have a good day.....

Answer:

The rate at which the distance between them is changing at 2:00 p.m. is approximately 1.92 km/h

Step-by-step explanation:

At noon the location of Lan = 300 km north of Makenna

Lan's direction = South

Lan's speed = 60 km/h

Makenna's direction and speed = West at 75 km/h

The distance  Lan has traveled at 2:00 PM = 2 h × 60 km/h = 120 km

The distance north between Lan and Makenna at 2:00 p.m = 300 km - 120 km = 180 km

The distance West Makenna has traveled at 2:00 p.m. = 2 h × 75 km/h = 150 km

Let 's' represent the distance between them, let 'y' represent the Lan's position north of Makenna at 2:00 p.m., and let 'x' represent Makenna's position west from Lan at 2:00 p.m.

By Pythagoras' theorem, we have;

s² = x² + y²

The distance between them at 2:00 p.m. s = √(180² + 150²) = 30·√61

ds²/dt = dx²/dt + dy²/dt

2·s·ds/dt = 2·x·dx/dt + 2·y·dy/dt

2×30·√61 × ds/dt = 2×150×75 + 2×180×(-60) = 900

ds/dt = 900/(2×30·√61) ≈ 1.92

The rate at which the distance between them is changing at 2:00 p.m. ds/dt ≈ 1.92 km/h

Answer:

2(13x – 7)

Step-by-step explanation:

Let G be some point on the diagonal line away from point E.

Angle DEG represents angle 1.

We're given that angle DEF is a right angle which means it's 90 degrees. Angle DEG is some angle smaller than 90 degrees. By definition, that must mean angle 1 is acute. Any acute angle is smaller than 90 degrees. There's not much else to say other than this is just a definition problem.

----------------

Extra side notes:

If angle 1 was a right angle, then that would mean angle GEF would have to be 0 degrees; however the diagram shows this isn't the case.

If angle 1 was obtuse, then there's no way we'd be able to fit it into angle DEF. In other words, there's no way to have an angle larger than 90 fit in a 90 degree angle.

Answer:

general formula is

r² = (x - x-center)² + (y - y-center)²

Answer:

6^10

Step-by-step explanation:

6^2 * 6^11

-----------------

6^3

First simplify the numerator.  We know a^b*a^c = a^(b+c)

6^(2+11)

-----------------

6^3

6^(13)

-----------------

6^3

Then a^b / a^c = a^(b-c)

6^(13-3) = 6^10

Answer:

6^10

Step-by-step explanation:

To solve this you need to remember 2 things.

First off, multipication is addition with exponents.

And secondly, division is subtraction with expoinents.

So on the top we have 6^2*6^11

So this is really 6^11+2

=

6^13

Now we need to divide by 6^3:

6^13/6^3

And this would tecnically be:

6^13-3

=

6^10

So the expression 6^10 is your answer.

Hope this helps!

Answer:

40

Step-by-step explanation:

the line in the middle shows the median

Answer:

20

Step-by-step explanation:

320 = 16x

Our objective here is to isolate the variable (x) using inverse operations

First we want to get rid of 16

16x is the same as 16 times x( which is multiplication)

The inverse of multiplication is division so to get rid of the 16 we divide by 16 ( but note: whatever you do to one side you must do to the other ) so we divide both sides by 16

320/16=20

16x/16 = x

We would be left with x = 20

This meaning that they would need 20 first grade classes

Answer:

The school will need 20 first grade classes

Step-by-step explanation:

So think about it. There are 320 first grade students and each class can have 16 students which represents the equation 16x=320

All you need to do is solve the equation 16x=320

The equation is multplication. To undo multiplication you need to do division

So, x=320/16

x=20

So overall, your awnser is 20.

Answer:

25

Step-by-step explanation:

Answer:

x = 25

Step-by-step explanation:

Okay so as you can see there is an x shape and whenever you have that it means they are verticle angles. So we can conclude that 25 is verticle to x and so x is equal to 25.

Answer:

40,608,000 km or 4.0608×[tex]10^{7}[/tex] km

Step-by-step explanation:

Speed(km/h) = Distance(km)/Time(Hours)

Distance = Speed × Time

6 days = 24 × 6 = 144 hours

282,000 km/h × 144 hours =  40,608,000 km

Answer:

x = 19

Step-by-step explanation:

These angles are supplementary meaning they add up to 180°.

7x - 1 + 3x - 9 = 180

10x - 10 = 180

10x = 190

x = 19

Answer:

C.) 48 degrees

Step-by-step explanation:

First you need to find x. We already know that is a straight line or 180 degrees, so you will make an equation to solve which is: (7x-1)+(3x-9)=180

To solve this equations you have to take away parenthesis and group like terms:

7x+3x-1-9=180 turns into 10x-10=180

Then you have to add ten to both sides then divide by ten and the answer is x=19

then you just have to find the angle of ABC by solving 3x-9, substituting 19 for x

Then the answer to that is 48 degrees

Answer:

2

Step-by-step explanation:

take any point

i am taking F

coordinate of F is (5 , 3)

F' is (10,6)

so use formula

(x , y) = (kx , ky)

(5 , 3) = (5k , 3k) = (10 , 6)

compare corresponding elements

5k = 10

k = 10/5

k = 2

3k = 6

k = 6/3

k = 2

note here k means scale factor

Answer:

Step-by-step explanation:

y = (x + 5)(x - 5)

  = x² - 5²

 = x² - 25

Degree of this polynomial is 2.

Highest power of the variable x will be the degree of the polynomial.

Answer:

a + b + c = 12

Step-by-step explanation:

The given information are;

a² + b² + c² = 138

a·b + b·c + c·a = 3

The required data = a + b + c

Using an online tool, we have;

(a + b + c)² = (a + b + c) × (a + b + c) = 2·a·b + 2·b·c + 2·c·a + a² + b² + c²

∴ (a + b + c)² = 2·(a·b + b·c + c·a) + (a² + b² + c²)

Where;

a·b + b·c + c·a = 3, and a² + b² + c² = 138, we have;

(a + b + c)² = 2 × 3 + 138 = 144

(a + b + c)² = 144

(a + b + c) = √144 = 12

a + b + c = 12.

Answer:

[tex]\frac{1}{18}[/tex]

Step-by-step explanation:

As the six-sided number cube had six sides, there are six events which could occur. There is only one interger less than 2 (1), therefore the probability of rolling a number less than 2 is [tex]\frac{1}{6}[/tex].

There are two events which could occur when flipping a coin. This means the probability of flipping heads is [tex]\frac{1}{2}[/tex].

To find the probability of both of these happening, you must multiply the fractions together by multiplying together both the denominators and numerators, therefore:

[tex]\frac{1}{6}[/tex] ×  [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{18}[/tex]

Answer:

1/12

Step-by-step explanation:

There is only one number less than two, which is 1, so you have 1/6 chance of getting a number less than two

Since a coin has two sides, you have 1/2, or 50% chance of landing on heads

If you multiply both of them, which is 1/6 times 1/2, you will get 1/12, since 1 times 1 is still 1, and 6 times 2 is 12.
